Automatic cable traction system and method for fully-mechanized mining face

Abstract

The invention provides an automatic cable traction system and method for a fully-mechanized mining face. The automatic cable traction system comprises a cable, a machine head guiding device, a machine tail guiding device and an automatic cable clamp tractor, wherein the machine head guiding device and the machine tail guiding device are fixed at the machine head and the machine tail of a scraper conveyer respectively; one end of the cable is fixed on a coal mining machine; the other end of the cable bypasses the machine head guiding device and the machine tail guiding device sequentially and is fixedly connected with the automatic cable clamp tractor; the coal mining machine is fixedly connected with one end of a cable clamp; the other end of the cable clamp bypasses the automatic cable clamp tractor under the traction of the coal mining machine, and automatically falls into a cable slot of the scraper conveyer. Through the automatic cable traction system and the automatic cable traction method for the fully-mechanized mining face, provided by the invention, the phenomenon that a flying waste rock (coal) injuries people is avoided, the labor cost is lowered, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a coal mining technology in a fully mechanized mining face, in particular to an automatic cable traction system and method for a fully mechanized mining face. Background technique [0002] At present, the shearer mainly digs coal on the fully mechanized mining face with an average inclination angle of 20° to 25°. The cables and cooling water pipelines that provide power to the shearer are often dragged with cable clamps. When the shearer is pulled downwards, the cable clamp is easy to slide down due to the action of gravity at the bend, and the cable slipping out of the cable trough will fall into the running scraper conveyor, which can easily cause the cable of the shearer to break and people to get an electric shock, etc. Major mechanical and electrical accidents, therefore, how to avoid the sudden drop of the cable during operation is an important problem that needs to be solved urgently in the coal mining process.

Problems solved by technology

[0004] However, although the above-mentioned method of manually protecting cables avoids the potential safety hazards caused by the sliding of the cables to a large extent, this method not only requires full-time personnel to operate before entering the hydraulic support column, but also requires multiple full-time personnel to cooperate with the operation. Therefore, in During the operation of the scraper conveyor, not only the flying gangue (charcoal) will hurt people, but also there will be waste of human resources and low production efficiency.
