Problems solved by technology

[0003] The existing self-moving hydraulic support structure is a front-to-back frame type with long dimensions. It is only used for coal mine roadway support and cannot be used for temporary support after the hydraulic support is withdrawn when the fully mechanized mining face is moved and reversed.

Abstract

The invention relates to a self-moving hydraulic support, which is used for supporting in time while assisting in a work surface support to retreat and move after the underground coal mine fully mechanized coal mining face finishes coal mining, and belongs to the field of coal mine machinery. The self-moving hydraulic support comprises an external frame top beam and an external frame base in a form with gaps at the middle and rear parts; an internal frame is nested in the gaps of the external frame top beam and the external frame base; and an internal frame base is connected with the external frame base through pushing a jack. The self-moving hydraulic support is used for supporting an empty roof in time when the work surface support retreats, so that the mechanization is realized, the risk of artificially maintaining the roof plate is solved, the labor intensity of workers is reduced, the production efficiency is improved, and a safe operation environment is provided for the workers. The self-moving hydraulic support is used for replacing pointed pillars or timber cribs, and the production cost is reduced.

Description

technical field [0001] The invention relates to a self-moving hydraulic support, which is used for timely support when the support of the auxiliary working face is moved and reversed after the coal mining in the fully mechanized mining working face of the coal mine is completed, and belongs to the field of coal mine machinery. Background technique [0002] The withdrawal of fully mechanized mining face equipment is a labor-intensive and time-consuming task. When the hydraulic support is withdrawn, one side of the support is a goaf, and the roof above the support has been affected by coal mining, and its stability has been greatly damaged, so the withdrawal of the support is more complicated. The original method of withdrawal is: after the support is withdrawn, the roof should be maintained in time with point columns or laying wooden piles. With the withdrawal of the support, the maintenance points or wooden piles cannot be fully recovered, so the cost is very large, and the ...
