Roadway advanced supporting supports capable of assisting machinery to move

Abstract

The invention provides roadway advanced supporting supports capable of assisting machinery to move. The roadway advanced supporting supports capable of assisting the machinery to move solve the problems that repeated supporting, complex operation and low working efficiency in the prior art for a floppy coal top roadway and a long-distance advanced supporting roadway. The roadway advanced supporting supports capable of assisting the machinery to move comprise advanced supporting supports which are composed of top beams, bases, and hydraulic upright columns which are connected between the top beams and the bases in a hinge joint mode and an auxiliary moving mechanism. The roadway advanced supporting supports capable of assisting the machinery to move are characterized in that the lower portions of the two hydraulic upright columns which are connected on one base in a hinge joint mode are fixed together through a fastening support, the lateral end of each top beam is connected with a top protective plate in a hinge joint mode through a telescope hydraulic cylinder, the two advanced supporting supports are a set in parallel in a transverse mode, a plurality of sets of advanced supporting supports are longitudinally continuously arranged along a roadway, and therefore supporting to a top plate is formed; and moving support mechanical arms are arranged between a set of two advanced supporting supports to be moved, are matched with a transport cart, and move each advanced supporting support along the roadway in a longitudinal sequence. The roadway advanced supporting supports capable of assisting the machinery to move are reasonable in structure and design, stable in supporting, convenient to operate, safe to use, and capable of reducing the effect of advanced supporting operation to working face coal mining production.

Description

technical field [0001] The invention relates to an advanced support device for safe operation of a fully-mechanized working face, in particular to an advanced support device for the advance section of the roadway in the working face while mining operations in the normal working face, and can be used with the working face. The roadway advance support bracket that is advanced and moved forward by the auxiliary machine for face mining. It belongs to the field of mining machinery manufacturing and application. Background technique [0002] The support of the roadway in the fully mechanized mining face mainly adopts U-shaped steel, I-shaped steel metal brackets, anchor rods, anchor nets and other joint support methods. It is necessary to strengthen the support at the leading section of the exit of the working face. In the coal mining operation of modern comprehensive mechanized mining, there are generally situations of high leading pressure. If it cannot be effectively supporte...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a roadway advance support bracket for auxiliary mechanical movement, which solves the problems of repeated support to the roof, slow moving speed, and problems in the prior art for relatively soft coal roof roadways and long-distance advance support roadways. Complicated operation, low working efficiency and other problems, its structural design is reasonable, the support is stable, easy to operate, safe to use, can adapt to the actual use needs of the site, reduce the impact of advanced support operations on the coal mining production of the working face, and is beneficial to coal mining Further improvement of the yield per unit area of ​​the working face
