Description

Technical Field

[0002] The power supply of underground electromechanical equipment is an important link in the production process of coal mines and other underground mines. It is responsible for providing electricity to all equipment, machines and miners in the mining area. The mine power supply system is mainly composed of multiple components such as generator sets, substations, transmission lines, distribution devices and transmission shafts. These parts work together to provide stable power to the mine. The routing of the transmission line requires the assistance of cable pay-off devices to unwind the cable and lay it on the planned transmission trough or ground transmission rack.

Stop pressing, insert the power supply cable between the two arc-shaped clamping plates, and then release the push handle. Under the action of the strong spring, the arc-shaped clamping plate clamps the power supply cable, which is convenient for quickly clamping and disassembling the ends of power supply cables of different sizes, thereby improving versatility.

[0036] Next, grasp the support seat 4 and push it with force to make it move in the chute 11 for position adjustment, so that the auxiliary guide wheel 41 and the guide wheel 755 are on the same vertical horizontal plane. Then, the cable passes through the auxiliary guide wheel 41, is guided by the guide wheel 755 and penetrates downward between the multiple second straightening wheels 756 and the multiple first straightening wheels 754. Then, rotate the adjusting screw 7532 to drive the displacement of the first straightening wheel 754 in the adjusting seat 753, so that the cable is squeezed by the multiple second straightening wheels 756 and the multiple first straightening wheels 754;

[0037] The controller 3 synchronously controls the operation of the reduction motor 5 and the driving motor 758.
