Description

Splint-free cable trough capable of being disassembled in layered mode

Technical Field

The utility model belongs to the technical field of a colliery working face scraper conveyor and specifically relates to a but splint-free cable duct of layering dismantlement.

Background

the cable trough is one of important parts of a scraper conveyor on a coal mine working face, is generally of an integral structure, the upper part is a guide groove of a reciprocating coal mining dragging cable of a coal mining machine, and the lower part is a laying channel of the scraper conveyor cable, a water liquid pipeline and a control line. The cable groove is connected with the middle groove through a bolt and is arranged on the mining side of the scraper conveyor. Generally, when a coal mining machine is maintained on a mining side, a maintenance worker needs to firstly drain high-pressure liquid in a liquid pipeline, pull out a cable, the liquid pipeline and a control line by enough length, then disassemble and assemble a cable trough at a relevant position, and install and reset the cable trough, various cables, pipelines and the like after maintenance. Therefore, cables, liquid pipelines and control lines can be lost, the labor intensity and unsafe factors of maintenance personnel are increased, the overhauling efficiency is seriously influenced, and the safe, high-yield and efficient mining of a coal mine is not facilitated.

At present, a cable trough with a reversible upper trough body is simple to operate, the upper trough body can rotate relative to the axis of a connecting sleeve of the upper trough body and the lower trough body, and after the upper trough body is reset, a positioning pin is inserted into positioning holes of the upper trough body and the lower trough body for fixing. However, in actual use, the positioning pin is very easy to lose, so that the upper groove body cannot be fixed, and finally the cable groove is damaged.
