The dispatching winch consists of eleven major parts: shunting and delivery, shunting iron bull, heavy hammer, heavy hammer bracket, pulley part, bracket parts, idler, guide wheel, tight rope device, and electric control part.

1. Dispatching winch - host

Commonly known as reducer, this reducer is a non-standard reducer designed and developed by coal itself. It has its own distinctive features: double output shaft, four-wheel friction, and four wheels rotate at the same speed in the same direction. The reducer shell is welded by steel plate, the first-order rotation adopts the arc-cone rack, and the rest are rotated by the spur gear. Gear material adopts 20CrMoTi, ZG40Cr, 17CrNiMo6, after quenching, carburizing, nitriding process, the normal service life can reach 5-10 years (except for wearing parts)

2. Tuning the car

Our company's iron cattle: cast, welded (track-changing, curved rail); gauges 900 and 1435 correspond to the passing railway and the end of the railway. The hook head configuration is based on C60, which fully considers the docking with the C70 wagon. (orbital track)

3. Heavy hammer

The weight is improved from the original round gray iron piece to a square steel piece, saving 210 USD / ton, and finally improved to welded filler parts, saving another 140 USD / ton.

4. Roller

For the use of tow ropes, the original gray iron parts are changed to nylon parts to save costs, the weight is saved by 60%, the transportation cost is saved accordingly, and the service life is extended by 100%. It is improved from the monolithic to the split type (70) and the hardness is increased by the quenching, but the cost is also increased.

5. Block, bracket, guide wheel:

Rotating parts, but low speed, copper sleeve structure, lubrication problems should be noted. If the lubrication is changed to a bearing structure, the lubrication effect can be improved, but the cost will increase.

6. Electronic control part

It can realize the low speed positive reversal of the winch and the high speed reversal of the empty car (PLC+ inverter + touch screen). The price difference between the two types is large.

1 The fuel system is not normal for many reasons. For example, the pressure of the oil pump is low, the fuel pump is not supplied with oil; the fuel filter is clogged, the spray atomization is poor, and there is air in the pipeline. Exclusion methods can be used to identify specific causes and take targeted measures such as repairing the fuel injection pump, replacing precision parts, cleaning the filter or removing air from the line.

2 Failure of the preheating device The failure of the preheating device will cause difficulty in starting at low temperatures, especially in winter. After finding out the cause, take corresponding measures. For the commonly used glow plug or electric flame preheater, if the resistance wire is damaged, it needs to be replaced with a new one;

If the startup circuit fails, check that the connecting wires are open and that the wires are in good contact with the terminals (screws) or switches.

3 The starting machine is not normal. The reason is mostly that the magnetic switch is in poor contact or the gear is not engaged with the flywheel ring gear. It is difficult to start. The magnetic switch should be repaired or replaced. If it is still difficult to start after replacing the magnetic switch, it may be that the starter motor or the gear is engaged. The starter motor or the gear should be repaired.

4 The starting speed is not enough. It is caused by insufficient battery power and can charge the battery.

5 If the ambient temperature is too low and the ambient temperature is lower than 5 °C, it is often impossible to start. The intake air temperature should be increased or the whole machine should be preheated with a charcoal grill to increase the temperature of the lubricating oil to make it easier to start.

6 If the fuel injection advance angle is too large or too small, it will affect the start. The fuel injection advance angle should be adjusted according to the instructions.

7 cylinder seal is not good, causing air leakage, the cylinder compression pressure is insufficient, or the cylinder inlet and exhaust valve are not tightly closed, which can cause difficulty in starting the diesel engine. In the case of engine cross-flow, the cylinder pressure can be used to check the cylinder pressure per cylinder. The vacuum of the intake manifold can also be used to judge the air leakage fault of the engine. On this basis, the cause of the analysis is analyzed. , to be excluded.

A radiation detector is a device that produces a secondary effect under the action of radiation, and this secondary effect can be detected by an electronic instrument.

When a particle passes through a substance, it absorbs all or part of its energy to produce ionization or excitation.

If the particle is charged, its electromagnetic field interacts directly with the orbital electrons of the atoms in the matter. (Coulomb force)

If it is gamma ray or X ray, first through some intermediate process, photoelectric effect occurs, Compton effect or electron pair is generated, part or all of the energy is transmitted to the orbital electron (secondary electron) of the substance, and then ionization or excitation is generated. .

For uncharged neutral particles, such as neutrons, charged particles are produced by nuclear reactions and then ionized or excited.

Radiation detectors use appropriate detection media as substances acting on the particles, transforming the ionization or excitation generated by the particles in the detection medium into various forms of information that are directly or indirectly acceptable to the senses. Immediately after the incident particle, the corresponding electrical signal is given, and after being amplified and processed by the electronic circuit, recording and analysis can be performed. Therefore, the radiation detector is an energy conversion element and is a basic component of the radiation measuring device.

First. Preparation before going down the well:

1. Check that the outer casing and the connecting part are in good condition and that the joint hose is equipped;

2. Check if the air path is unblocked: Pull the piston in parallel with the three-way switch and the cylinder to check the air inlet, and hang the three-way switch and the cylinder.The straight device pushes the piston to check the air outlet;

3. Check the flexibility of the piston: reciprocally push and pull the piston 3-4 times in parallel with the three-way switch and the cylinder to make it flexible;

4. Check the air tightness: twist the three-way switch to a 45° angle with the cylinder, pull the piston, pull it quickly, and quickly restore or live the piston.The scale on the plug back to no more than 5ml indicates good air tightness.

5. Not less than 30 types of verification tubes;

6. Check the integrity of the verification tube, the maximum value of the verification tube, the prescribed air supply time, the prescribed air supply amount, type, and service life.

Second, the multi gas detector operating procedures:

Arrive at the location to be tested, parallel the device with the three-way switch and the cylinder, take the air from the upper part of the roadway, push and pull the piston 3-4 times to clean the piston.

Pull out slowly the last time, then quickly twist the three-way switch to a 45° angle to the barrel. Take a longer test tube, first observe the specified air supply and air supply time of the identification tube, open both ends of the verification tube, the zero position is facing downward, and the scale is facing itself.

The verification tube is inserted into the joint hose, and then the three-way switch is twisted into a vertical position with the cylinder, and the air is supplied at a constant speed within a predetermined time.

The position where the color changing ring moves. The concentration of carbon monoxide is read according to the actual moving scale on the verification tube.

Three inspections:

1. Constant check: The multi gas detector operation method is the same as above, the specified air supply amount can be sent at a constant speed within the specified time, and the direct reading can be performed on the verification tube.

As a constant, the concentration of carbon monoxide is the value displayed by the verification tube.

2. Micro-inspection: The operation method is the same as above. After the specified air supply volume is delivered at a constant speed within the specified time, the test tube cannot read.

Take the same method to use the same test tube to repeatedly send air to check, the amount of gas is the same every time, the inspection results

The result is divided by the number of aspirations, which is the true content.

Namely: carbon monoxide concentration = reading on the verification tube / number of air supply

3. Concentration check: The operation method is the same as above, and the air is supplied at a constant speed within the specified time. When the specified air supply volume is not reached, the verification tube has reached

To the maximum value, the concentration of carbon monoxide at this time = the maximum value of the test tube × the prescribed air supply amount / the actual air supply amount. High concentration of mono-oxidation

Carbon can be inspected after thinning, and the result is multiplied by a thin multiple, which is the true content.

Precautions

1. In the case of constant check, the test tube is 100ml, and the test tube with air supply time of 100 seconds or 200 seconds needs to be sent out.Gas is the true concentration of the gas to be tested.

2. For traces and concentrations of carbon monoxide, the test tube of the corresponding measurement range should be selected for measurement.

3. When detecting gas, first observe the expiration date and measurement range of the verification tube. Understand the value represented on the verification tube

The concentration is tested according to the verification tube instructions. (Generally carbon monoxide, carbon dioxide, oxygen are 50ml; hydrogen sulfide is 100ml, 100 seconds; nitrogen dioxide is 50ml, 25 seconds)

4. If the gas nozzle is blocked, the valve can be pulled into the vertical position of the cylinder, the gas sample is removed from the air outlet, and then pulled into a 45° rear insert.Verify the tube and pull it into a vertical position to send the gas out.

5. Conversion relationship between percentage and ppm 1% = 10000 times the ppm value

Ultrasonic is a kind of sound wave that is beyond the hearing range of the human ear (greater than 20 kHz). In order to be able to detect such sound waves, we must use a sound wave that can capture the ultrasonic frequency and can convert the sound waves that can be heard by the adult ear. Instrument. The Ultrasonic Leak Detector (SDT270) R&D and manufacturing center is located in Brussels, the capital of Belgium in northwestern Europe. The core business area is the measurement system for high-tech leak detection, air tightness testing and predictive maintenance for industrial maintenance and quality control.

Ultrasonic Leak Detector working principle:

The ultrasonic leak detector is a kind of ultrasonic signal generated by detecting a partial discharge, and frequency conversion is performed, and the ultrasonic signal is converted into a sound that can be heard by the human ear and a displayed value, thereby finding a partial discharge point and eliminating a hidden danger. The characteristics of different types of partial discharge sounds are different, so it is possible to judge which partial discharge failure is caused by the difference in sound. The intensity of the partial discharge can be quantified by the magnitude of the value. Ultrasonic waves have directionality and can be positioned for local discharge points.

Do you really have to repair the road roller? If the maintenance is unreasonable, it will cause a series of malfunctions. The following is a brief introduction to the maintenance and repair of the road roller.

1. New products are not selected

The road roller for replacing the cylinder liner of the roller must check the size group code of the standard cylinder liner and the piston. The cylinder liner and the piston to be installed must have the same size code of the two to ensure the standard matching clearance.

2. Cylinder gap measurement is not allowed

The measurement is based on the clearance in the direction of the long axis of the ellipse, that is, the measurement of the piston skirt perpendicular to the piston pin hole.

3. Open flame heating piston

The open flame directly heats the piston. The parts of the piston are thin and uneven, and the thermal expansion and contraction are different. It is easy to cause deformation. If a certain high temperature is reached, the metal structure will be damaged after natural cooling, and the wear resistance will be reduced, and the service life will be greatly shortened.

4. Abrasive cloth grinding bearing

Many road roller maintenance workers increase the contact surface between the tile and the shaft, and sand cloth is used to polish the bearing bush. Because the sand is hard and the alloy is soft, the sand is easily embedded in the alloy during grinding, and the wear of the bearing pad is accelerated when the engine is working, and the service life of the crankshaft is shortened. .

5. The oil can only be changed.

The used oil has a lot of mechanical impurities, and even if it is exhausted, there are still impurities in the oil pan and oil passage.

6. Grease is messed up with mess

Some road roller repairers prefer to apply a layer of grease on the cylinder head when installing the cylinder head gasket. The cylinder gasket not only requires strict sealing of the high temperature and high pressure gas generated in the cylinder, but also seals the cylinder head and the cylinder with a certain pressure and flow rate. Water and oil, grease is applied to the cylinder head gasket. When the cylinder head bolt is tightened, a part of the grease will be squeezed into the cylinder water channel and the oil passage. When the grease remaining between the cylinder heads is working in the cylinder, the high temperature and high pressure gas is easy to be used. Impact, destroying the cylinder head gasket, causing air leakage. In addition, when the grease is exposed to high temperature for a long time, it will produce carbon deposits, causing the cylinder mat to deteriorate prematurely.

7. The bolt is too tight

The pre-tightening force causes the screws and bolts to break or the thread to slip.

8. Tire pressure is too high

Too high and low tire pressure will affect its service life, and it is also unfavorable for road roller safe driving.

9. The water tank "opens the pot" and adds cold water.

Add cold water, because the temperature difference is too large, it will cause the cylinder head and cylinder to "explode". Therefore, once the water tank is “opened” in use, emergency measures should be taken to ensure that the engine cooling water cools down on its own.

As a protective device on the parking space, the buffer stopper is essential, although its role is to prevent the wheel offside, but also combined with the installation area. It is necessary to consider whether the parking lot is open or underground, and whether the parking space is public or personal.

Taking plastic buffer stopper and aluminum alloy buffer stopper as an example, we must first understand the specifications and materials of the next two car stops.

The rubber used in the rubber buffer stopper is molded by high polymerization and the inside is triangular lacing. According to the physical principle, the internal structure is designed to be triangular and more stable and stable. Two sets are installed, and the three fixed points are triangular. Here, considering the fixed performance, two reflective films are attached on the front sides, and other safety protections are provided. The facilities play a warning role. The price of the rubber buffer stopper is relatively economical. The average price ranges from 15 to 30 yuan, which is also the most common style.

The metal buffer stopper is traditionally available in the metal buffer stopper with both triangular and round tube specifications, which are post-weld and painted. Here I mainly talk about the aluminum alloy buffer stopper, her whole structure is cast in one time, so there will be no solder joint breakage, plus the raw material is aluminum alloy, with anti-corrosion BUG. The surface paint is the same as the paint used in automotive paints, in order to maximize the surface gloss. Another thing worth mentioning is that his appearance is completely different from the existing buffer stopper, and it is soluble in the aesthetic design under the premise of safety and sturdiness. Make it even more atmospheric. Because of this, its scope of use is also clear. Some shopping spaces in the mall, private parking spaces in the community, and large villas within the group.

There are many differences between the two. Here we will analyze the points in combination with the actual points.

Different prices: different positioning, different materials, it also clarifies the price level, rubber buffer stopper as a pro-people, his production materials and processing technology is relatively simple, so the price is low. The raw material and processing technology of the aluminum alloy buffer stopper are strict, and the processing process is cumbersome, and the price will be slightly more expensive.

Different lifespan: The rubber type buffer stopper has a certain elasticity and the hardness is not high. If it is installed outdoors, it will be corroded by external factors such as sunlight, rain and air. The life expectancy will be shorter.

The effect is different: the design of the aluminum alloy buffer stopper is one of its highlights, but also a big buy. The parking lot is matched with it, and the overall style of the parking lot will be different.

Pipe Inspection Crawler Camera Robot

As an important means of material transportation, pipelines have a wide range of applications. During the use of the pipeline, due to various factors, various pipeline blockages and pipeline failures and damages may occur. If the pipeline is not inspected, repaired and cleaned in time, it may cause an accident and cause unnecessary losses. However, the environment in which the pipeline is located is often difficult to directly reach or allow people to directly enter, and it is very difficult to detect and clean. Therefore, one of the most effective methods is to use the pipe inspection crawler camera robot to realize on-line inspection, maintenance and cleaning in the pipeline.

The pipe inspection crawler camera robot is composed of a controller, a crawler, an HD camera, a cable, and the like. At the time of the operation, the controller controls the crawler to carry the detection device into the pipeline for detection. During the inspection process, the pipe inspection crawler camera robot can transmit video images of the internal conditions of the pipeline in real time for professional maintenance personnel to analyze the internal faults of the pipeline.

The advantages of using a pipe inspection crawler camera robot:

1. High security. Use large-scale pipe inspection crawler camera robots to enter the pipeline to find out the internal conditions of the pipeline or eliminate hidden dangers of pipelines. If it is manual operation, there are often large potential safety hazards, and the labor intensity is high, which is not conducive to the health of workers. The intelligent operation of the large pipe inspection crawler camera robot can effectively improve the safety performance of the operation.

2, Saving labor. The pipe inspection crawler camera robot is small and light, and the operation can be completed by one person. The controller can be installed on the vehicle, saving labor and saving space.

3. Improve efficiency and quality. The intelligent engineering of the pipe inspection crawler camera robot is accurate and can display the date and time, the inclination of the crawler (pipe slope), the air pressure, the crawling distance (the number of meters), the laser measurement result, the azimuth (optional), etc. The display state of these messages is set by the function keys; the lens angle of view clock display (pipeline defect orientation).

4, High protection level, camera protection grade IP68, can be used for 5 meters water depth, crawler protection grade IP68, can be used for 10 meters water depth, have airtight protection, material waterproof rust and corrosion, no need to worry about quality problems, because the work only the best pipe inspection crawler camera robot in the country.

5, High-precision cable reel, retractable line does not affect each other, optional length.

With the help of the pipe inspection crawler camera robot, faults and damages in the pipeline can be easily found, which not only saves manpower but also reduces the amount of construction and greatly enhances work efficiency. Pipe inspection crawler camera robots will become the main trend of pipe network inspection in China. The application of pipe inspection crawler camera robots in national pipe network surveys is also an inevitable choice.

Pipe inspection crawler camera robots have changed the traditional pipeline inspection technology, which makes our work easier and easier, and will continue to develop pipe inspection crawler camera robots dedicated to making the best pipeline inspection robots.

Pipe inspection crawler camera robots mainly use closed-circuit television detection technology to detect the internal conditions of pipelines, also known as "CCTV pipe inspection crawler camera robots."

CCTV pipe inspection crawler camera robots have been matured abroad, and have achieved a lot of results in the field of in-pipe operation robots, mainly used in pipeline inspection, maintenance and cleaning of air-conditioning ventilation ducts.

Pipe inspection crawler camera robots have been developed in China in recent years and are developing rapidly. The reason is that there are still many problems in the pipeline inspection pipeline in China, and the pipeline inspection technology in China has not been updated. To this end, we have made market analysis and report on domestic pipe network testing. 91% of China's urban pipe network has more or less problems. This is why many urban drainage systems will appear Series of questions in the rainy season every year.

The urban underground pipe network includes urban water supply, drainage, power supply, gas supply, communication, etc. It is an important part of the urban infrastructure. The underground pipe network is the city's "blood vessels" and nerves, and is also the lifeline of the city. With the rapid development of urban construction, China has increased the development and utilization of underground space in recent years. There are more and more underground pipe networks laid in cities. However, due to the large number of property rights units involved in the underground pipe network, there is a lack of unified standard management. The archives of the underground pipe network are not uniform, which leads to the unclear situation of the underground pipe network. With the concealment of the underground pipe network, the actual location and depth of the pipe network cannot be determined. The damage to the underground pipe network during construction will occur to the city. Construction management and old city transformation have brought hidden dangers.

In order to solve the current situation of urban pipe network inspection and management, the organization team researched and analyzed this project, and developed a CCTV pipe inspection crawler camera robot to specifically deal with urban pipe network detection.

The CCTV pipe inspection crawler camera robot is a set of mechanized and intelligent equipment for recording the internal conditions of the pipeline. It performs real-time impact monitoring, recording, video playback, image capture and video file storage on the internal conditions of the pipeline without personnel entering. The inside of the pipe can be understood inside the pipe.

The CCTV pipe inspection crawler camera robot is suitable for the detection of sewage pipelines, rainwater pipelines, rainwater confluence pipelines, tanks and inspection wells. China has a vast territory, a large span of drainage pipeline construction, various forms of pipelines, and various construction methods. In particular, in recent years, the pipelines used in China's drainage pipelines have emerged in an endless stream, resulting in a wide variety of pipeline conditions.

The excavator is a farmland construction machine for excavating earthwork. It can be used to excavate reservoirs, fish ponds, ditches and clearing channels.

Using an excavator can effectively improve engineering efficiency and save manpower. There are two types of shovel excavators and backhoe excavators according to their configuration on the tractor. On the tractor equipped with the backhoe excavator, and then the front-mounted device, it becomes a backhoe loader, which can be completed.

Digging and loading two jobs.

The excavator consists of a bucket, a bucket column, a swing arm, a foot or support wheel, and a hydraulic system. The bucket is hinged to the bucket column and the bucket column is hinged to the end of the swing arm. The hydraulic system controls the lifting and lowering of the swing arm and the rotation in the horizontal plane through each special cylinder, and the bucket column rotates in the vertical plane.

The movement, the lifting and lowering of the feet, and the digging, lifting and unloading of the buckets enable the bucket to excavate the earth at a height of 3 to 4 meters above and below the ground and discharge the soil to a designated location.

What is the use of the backhoe loader? Here are a few different working devices of the excavator to learn more about the role of the excavator! !

The extension arm belongs to the excavator work unit and is a long arm specially designed to lengthen the effective working range of the excavator. It is called an extension arm. According to the way of operation, it is divided into: demolition and long arm, deep pit and long arm, piling and long arm.

Super hydraulic shear

Hydraulic shears are mainly used for the disposal of scrap metal, the demolition of buildings and the reconstruction of roads and bridges. Can cut a variety of different materials, including construction steel, motorized rail cars, steel plates, steel pipes, steel, steel, round stones, concrete, masonry, wire and cable, tires and wood.

Grab steel machine

Grab the steel machine, as the name suggests is the machine that grabs the steel. The size of the steel grab is commonly called the “grab arm”, which is generally long. The front end is the steel grabber, which is also the gripper, also known as the plum blossom hydraulic grab. The main function of the orange pet grab is to carry out the loading and unloading operations of various materials such as scrap metal, industrial waste, crushed stone, construction waste and domestic garbage.

Ripper

The ripper is a working device that directly contacts the soil of the excavator. Because it is shaped like a hook-shaped bucket device, it is also called a bucket hook; because more working conditions are more complicated, such as harder If the soil is infiltrated with gravel or all of the rock, it is impossible to complete the excavation with the bucket. Therefore, the soil or rock should be loosened by the ripper and then loaded with the bucket. Excavator belt ripper can also replace the trouble of shooting in the case of red earth rock weathering rock. Mainly used for floor cleaning, site preparation, sidewalk and road surface stripping, and high-strength excavation operations.

Wood grab

The wood grabber is one of the excavator work devices and is specially produced for the specific work requirements of the excavator. The main function of the wood grabber is to grab the handling and handling of scrap metal, stone and wood.

What is your understanding of the excavator now?
