Background
When the comprehensive excavator works in a coal mine, the power supply cable is dragged and moved on the ground along with the continuous forward movement of the comprehensive excavator, so that one to two workers are required to drag the cable along with the forward and backward movement of the mobile equipment in order to avoid the damage of the cable, and if mud, water or rolling and other sharp objects exist on the ground, the cable is dragged for a long time to cause the water entering or the puncture and the crush of the cable. The labor intensity of workers is quite high, the cables can be rolled and scratched without worry, cable short circuit or electric leakage accidents often occur, so that the equipment cannot normally operate, the life safety of the workers can be threatened, and unpredictable and serious potential safety hazards can be caused in coal mines in case of gas outburst or flammable and explosive places. And difficulty is added to quality standardization construction management. Some cable dragging devices are dragged by a motor in recent years, and starting motors for underground operation need strict explosion-proof devices, so that the cable dragging devices are complex in structure, high in manufacturing cost and high in maintenance cost, and are difficult to popularize and use.
