Description

Technical Field

[0002] Cables play an important role in providing power to various equipment such as coal mining machines, conveyors, and lighting systems in coal mines. The smooth laying of cables is the premise and guarantee for the normal operation of various equipment and facilities. Currently, various cables in coal mines are mostly laid by manual dragging, which has the following disadvantages:

[0003] First, in the process of laying cables, it is necessary to pass various obstacles (scraper conveyors, belt conveyors and other equipment or on-site material stacking equipment). Personnel should be arranged at both ends of the obstacles that need to be passed to check whether the cable is stuck or damaged by friction during the cable laying process, which increases the labor input.

[0004] Second, the cable is prone to rubbing against the side of the tunnel at the corners: at this time, the cable is very likely to be scratched by friction, and at the same time, the dragging resistance is increased, which indirectly increases the labor intensity of the cable dragging personnel. The personnel may also be squeezed to the coal side, increasing the risk factor of the operation. Utility Model Content
