Advance support bracket set special for conveyor gateway on fully-mechanized coal mining working surface

Abstract

The invention relates to the field of advance support equipment, in particular to an advance support bracket set special for a conveyor gateway on a fully-mechanized coal mining working surface. The bracket set is at least composed of two hydraulic bracket units. Lower parts between the hydraulic bracket units are connected through a push-pull jack. Upper parts between the hydraulic bracket units are connected through a drawer sliding beam mechanism. Bottoms of hydraulic upright posts of the hydraulic bracket units are hinged with a base. Tops of the hydraulic upright posts are hinged with a top beam. The bottom of the top beam is hinged with a shield beam. The lower part of the shield beam is hinged with the base through a front connecting rod and a rear connecting rod. A lateral protective beam unit is also hinged with the side surface of the top beam. An edge protection plate is hinged with the front end of the lateral protective beam unit. According to the invention, the problems that the advance support bracket set special for the conveyor gateway on the fully-mechanized coal mining working surface is difficult to arrange, is even interfered with equipment in the conveyor gateway, and the like because of the factors of concentrated equipment in the conveyor gateway, narrow space, high reciprocating movement quantity of the head of a scraper machine and an elevating conveyor along a coal flow direction of the working surface and so on can be solved effectively. The mechanized support is realized.

Description

technical field [0001] The invention relates to the field of advanced support equipment for transportation along the trough of fully-mechanized mining working faces in coal mines, in particular to a special advanced support bracket set for transportation along troughs of fully-mechanized mining working faces. Background technique [0002] With the increasing number of mechanized coal mining faces in coal mines, especially the increasing number of high-efficiency, high-yield and high-efficiency working faces, the support management of the fully-mechanized mining face's transportation and trough roof is very important, and has become the key to the production efficiency of the working face. one of the factors. At present, two methods are generally used to support the roof of the fully mechanized mining face: one is a single hydraulic prop, which is fully supported by manpower, and the single hydraulic prop is retracted, resulting in a large number of people in the working face...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a fully mechanized coal mining face transportation and trough special advanced support bracket group with reliable functions, strong adaptability to the space characteristics of the fully mechanized coal mining face transport along the trough, and to solve the problem of the existing fully mechanized mining face The single hydraulic prop in the transportation trough has poor safety, low efficiency, high cost, difficulty in arranging the advance support bracket, and easy interference with other equipment. High yield and high efficiency
