Abstract

The invention relates to an enhanced hydraulic support which comprises a base, a beam body and stand columns; the beam body is connected with the right end face of the base in a rotating connection mode; the stand columns are symmetrically and fixedly installed on the front side and the rear side of the upper end face of the base; the upper end faces of the stand columns are connected with the beam body in a rotating connection mode; the base comprises a bottom plate, a fixed block, a sliding rail, a material conveying groove, a first magnet, a sliding block and a second magnet; and the beam body comprises a first connecting rod, a second connecting rod, a shield beam, a balance jack, a top beam, a telescopic beam and a side protection plate. According to the enhanced hydraulic support, through the base, gangue produced in coal mining operation is quickly stored, so as to reduce discharge of the gangue so as to improve the efficiency of the hydraulic support in the coal mining operation; and by means of the stand columns in the beam body, when one stand column breaks down, the hydraulic support can still be used, and coal mining operation is prevented from being affected.

Description

technical field [0001] The invention relates to the field of hydraulic supports, in particular to an enhanced hydraulic support. Background technique [0002] The hydraulic support is a structure used to control the mine pressure of the coal mining face. The mine pressure of the mining face acts on the hydraulic support in the form of external load. The resultant force of the support and the resultant force of the external load acting on the hydraulic support by the top plate are exactly in the same line, so the hydraulic support is very suitable for the surrounding rock of the mining face. The hydraulic support is composed of columns, jacks, load-bearing structural parts, pushing devices, control systems and other auxiliary device composition. [0003] In the process of using the hydraulic support, due to the structural limitations of the hydraulic support, the following problems exist in the actual operation process: [0004] (1) During the use of the traditional enhance...
