Although the majority of users use the scraper winch, although they know how to operate, but the specific operation steps and routine maintenance of the scraper winch may not know very clearly, I will explain in detail the "Scraper Winch Operation".
Step / Method
1
Check before work or open an empty test drive, pay attention to the lubrication condition is good, do not use dirty, non-standard lubricants when adding lubricant. And always pay attention to whether the temperature rise is normal, when the scraper winch has a faulty problem, it is not allowed to continue to work. The leader should be informed and the maintenance master should be assisted to eliminate the fault.
2
When the motor is started, the transmission gear starts to run. At this time, the brake band on the reel is clamped, and the shank on the large gear should be loosened, so that the reel does not rotate, and only the large internal gear rotates.
3
To start the reel, the brake band on the roll must be completely loosened and the brake band on the large internal gear must be tightened. At this time, the reel is rotated and wound up to work.
4
During the working process of the scraper winch, if the scraper winch is temporarily stopped, the brake band of the upper wheel should be loosened and the brake band on the reel should be tightened.
5
When the position of the towed load is scheduled by the micro-range, it is only necessary to alternately lift or press the left and right brake levers to stop the revolving between the reels. When operating the brake lever, attention should be paid to the protection of the shoulder pin, the joint bolt and the pad.
6
If the parking time is long, you should hold the brakes and turn off the motor.
7
The opening and stopping of the reel must be rapid to reduce the wear of the brake band, but it is not allowed to drive and stop in a hurry to prevent damage to the transmission.
8
When there is often a counter-torque effect on the scraper winch reel, both brakes must be in good contact and secure.
9
When the motor is running, the two brakes cannot be braked at the same time to prevent the motor from being burnt.
Always pay attention to the working condition of the brakes. If the brakes are not working, they must be adjusted. The grease and dirt that falls on them must be cleaned.
The temperature of the drum brake belt and bearing of the scraper winch shall not exceed 70 °C. If the temperature rises drastically, it must be stopped for inspection.
The seal must be intact to prevent dust ingress and oil spillage.
Check whether the rope head is secure, whether there is damage or biting inside the transmission mechanism, and whether the internal parts are excessively worn. Only after checking and confirming that it is correct can you drive.
The temperature of the motor should not exceed the specifications of the machine.
The scraper winch must not exceed the rated load for work.
Each team must carefully maintain the various parts of the scraper winch every day, remove dirt when leaving work, and there should be no dust on the motor.
Employees in charge of maintenance must check the use of the scraper winch frequently, assist in the handling of temporary failures, conduct regular inspections of the scraper winch, prevent malfunctions and accidents, and make maintenance records.
If the scraper winch is left unused for a long time, appropriate measures should be taken to protect it from rust or damage.
For the specific repair of the scraper winch, please refer to the eight methods of common fault handling of the scraper winch.
Precautions
1.When the motor is running, the two brakes cannot be braked at the same time to prevent the motor from being burnt.
2.The temperature of the drum brake belt and bearing of the scraper winch shall not exceed 70 °C. If the temperature rises drastically, it must be stopped for inspection.
3.The scraper winch must not exceed the rated load for work.
4.Check before starting work or drive an empty car.
5.If the scraper winch is left unused for a long time, appropriate measures should be taken to protect it from rust or damage.
