Flexible shield-type hydraulic support for coal mine

Abstract

The invention relates to a light flexible shield-type hydraulic support which aims to steep occurrence coal seam and is used to support the working face using the bow pseudo-inclined arrangement mode. The hydraulic support comprises a top beam and a shield beam, a hinging connector which is used to hinge adjacent top beams is arranged at the belly of the top beam, a hydraulic bi-directional column is vertically installed at the bottom surface of the top beam, a yawing hydraulic bi-directional column is installed at the joint part of the top beam and the shield beam. An end supporting seat is hinged at the front end of the top seam, a turnover shield plate with adjustable inclined angle is installed at the lower end of the shield beam, a steel wire rope seat is installed on the shield beam, a steel wire rope which is used to connect adjacent shield beams is arranged in the steel wire rope seat. The invention effectively resolves the problems that the support intensity of the existing support is low, the support is easy to deform and crack owning to inadequate intensity of the support, the injury fault for roof leakage is easy to occur between the supports. The steel wire rope connected with the support is easy to fold and deform to break, the workload of workers is great for the frequent dismounting of the support, the labor intensity is over high, the support is easy to be damaged and is not easy to be replaced, and the collapse gangue is not easy to be controlled and the like.

Description

technical field [0001] The present invention relates to a kind of hydraulic support equipment used in the working face of steeply inclined coal seams for safe underground mining of coal mines, in particular to a kind of hydraulic support equipment suitable for steeply inclined horizontal layering and oblique cutting layered mining, and used for supporting the surrounding rock of the stope. Flexible cover type hydraulic support. Background technique [0002] Coal mine support equipment is an important guarantee for coal miners to mine coal safely. The selection of hydraulic support for coal mining face of coal mine underground workers is a reliable safety support equipment in the production process. At present, there are high-yield and efficient self-moving fully mechanized mining hydraulic supports suitable for simple coal seam conditions, and light sliding supports and suspension supports suitable for small coal seams and small and medium coal mines. Whether it is a fully ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a flexible cover type hydraulic support suitable for safe mining of steeply inclined complex difficult-to-mine coal seams, especially a light flexible cover type hydraulic support for mining working faces arranged in a downward pseudo-inclined manner for steeply inclined coal seams. Hydraulic support, to solve the low support strength of the existing support. Because the support itself is not strong enough, it is easy to deform and crack, and the roof is easy to leak between the supports and hurt people. , the labor intensity is too large, the bracket is easily damaged and difficult to replace, and the collapsed gangue is not easy to control, etc.
