Chain fast-insertion conveyor cable groove for cable dragging of coal mining machine

Abstract

The invention relates to the technical field of fully-mechanized coal face exploitation and transmission under an underground coal mine, in particular to a conveyor cable groove for a cable dragging device of a coal mining machine. By the conveyor cable groove, rapid disassembly and assembly of a chain can be achieved. The cable groove comprises a cable groove body, a baffle plate, a left chain cover, a right chain cover and a press plate, wherein the press plate is inserted onto a bottom plate of the cable groove body, the left chain cover is pressed by a front end surface of the press plate, a boss is clamped at a lower edge of a vertical plate, the press plate and the right chain cover are fixed on an outer side plate of the cable groove body by bolts to form a closed chain (P) and an open chain (Q), so that a left sliding way (H) and a right sliding way (J) are arranged at the same horizontal position. By the cable groove, the usage ratio of a fixed piece can be reduced, the labor intensity of a worker is reduced, the operation time of a worker in a working surface dangerous environment is reduced, and the installation and maintenance efficiency of equipment and the safety of coal mine exploitation are improved.

Description

Technical field: [0001] The invention relates to the technical field of mining and transportation of fully mechanized mining working faces in underground coal mines, in particular to a chainway quick-insert conveyor cable trough used for cable dragging of a coal mining machine. Background technique: [0002] In the prior art, there is a shearer cable linkage device used for conveyors in fully mechanized mining faces. When it works, it relies on the reciprocating movement of the tow cable frame in the cable trough to tension the cable, and the power of the tow cable frame is driven by the chain. transfer. The cable trough used in this device is provided with a chain channel, which is a welded structure or a bolt-fixed structure. It is difficult for the welded chain channel to pass through the chain during the installation of the towing cable device, and the daily maintenance is difficult. When the chain channel is excessively worn and needs to be replaced, it must be replaced...

AI Technical Summary

Problems solved by technology

The cable trough used in this device is provided with a chain channel, which is a welded structure or a bolt-fixed structure. It is difficult for the welded chain channel to pass through the chain during the installation of the towing cable device, and the daily maintenance is difficult. When the chain channel is excessively worn and needs to be replaced, it must be replaced. Replacing the cable trough as a whole brings unnecessary waste; the existing bolt-fixed structure chains are two chains fixed separately, and the amount of bolts used is large, which is not conducive to reducing labor intensity and improving work efficiency. Operating hours in hazardous environments, detrimental to safe mine construction
