The support equipment in the mine is often the Infrastructure Roof Support. It has a simple structure, low cost and can be recycled. Although there are many models of the Underground Roof Support, is the architecture of the Under Roof Roof Support the same for each model? Underground Roof Support is subject to high pressure, long support time and easy installation and deformation.
Structural composition of Underground Roof Support
The top beam is arc-shaped, and its number is divided into one section and multiple sections depending on the section size of the roadway, the force of the bracket, and the transportation conditions.
There are three types of legs: one is a circular arc at the top and the straight segment at the lower part; the second is all curved and has only one radius of curvature; the third is all curved, but has two curvatures. radius. A base is welded under the column leg, and the size of the base depends on the hardness of the bottom plate;
The connecting piece is a clamping device between the bracket section and the inter-section, which can be used for the connection between the joints, and can also press the two sections of the connected steel joints to provide a pre-tightening force, so that the U-shaped steel has frictional force, thereby ensuring The arched bracket has working resistance and shrinkage.
The role of the inter-rack tie rod is to enhance the overall relative stability of the bracket, and the brackets are coupled from the longitudinal direction to form a whole.
