Cable clamp dragging device of coal cutter

Abstract

The embodiment of the invention discloses a cable clamp dragging device of a coal cutter. The cable clamp dragging device comprises a driver head, a rotary machine tail, a traction device part and a bracket. The driver head consists of a driver motor and a drive sprocket that are installed on the bracket respectively; and the driver motor drives the drive sprocket to make rotation. The rotary machine tail includes a rotary sprocket wheel installed at the bracket in a rotating manner; and the drive sprocket and the rotary sprocket wheel are connected by a chain. The traction device consists ofa support base and a cable clamp rotary wheel for dragging a cable clamp to move in a cable trench; the cable clamp rotary wheel is installed on the support base in a rotating manner; and the supportbase is fixed on the chain; the drive sprocket drives the chain to rotate and the chain drives the cable clamp rotary wheel to move by the support base, so that the cable clamp is driven to move in the cable trench. Therefore, the cable clamp can be dragged automatically to prevent multi-layer superposition the clamp clamp in the cable trench and avoid separation of the cable clamp from the cabletrench.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of coal shearer towing cables, in particular to a coal shearer cable clamp dragging device. Background technique [0002] In the mechanized fully mechanized mining face of modern coal mines, the power supply cables and water supply pipelines of the shearer are installed in the special cable clamps for the shearer, and the cable clamps are placed in the cable trough of the conveyor, and are dragged by the shearer. When the shearer is repeatedly adjusted to travel, especially when the shearer is cut into the knife and the nose and tail of the machine are cutting the triangular coal, the cable clamp is prone to multi-layer superposition. When the stacking height of the cable clamp is higher than the cable groove, there will be a phenomenon of de-grooving, and the de-grooved cable clamp will fall to the conveyor due to its own weight. [0003] At present, the way to deal with the cable...

Problems solved by technology

[0003] At present, the handling method of the cable clamp falling out of the groove is to be maintained by a special person with the machine to prevent the cable clamp from falling out of the groove, or to manually handle the cable clamp after falling off the groove, such as putting the removed cable clamp back into the cable groove, which is time-consuming and laborious

Moreover, the shearer pulls the cable clamp with great strength. If the cable clamp is not put back into the cable groove in time, the shearer will easily break the cable, causing electrical accidents and affecting production.

In severe cases, an ignition source will be generated, causing gas combustion and explosion accidents, and seriously threatening mine safety
