Four-column suspension swinging beam type gangue filling hydraulic support

Abstract

The invention relates to a four-column suspension swinging beam type gangue filling hydraulic support. The four-column suspension swinging beam type gangue filling hydraulic support comprises a front top beam, an Y-shaped upper connection rod, and a rear top beam, a stand column, a balance jack, a swinging beam, a swinging beam jack, a rear connection rod, a front connection rod, a foundation, a pushing frame, and a pushing jack which are connected with the front top beam; the stand column is supported between the front and rear top beams and the foundation; the upper end of the Y-shaped upper connection rod is connected with a connection point of the front and rear top beams; the Y-shaped upper connection rod, the front connection rod, the rear connection rod, and the foundation are connected two by two to form a four-connection-rod structure; the swinging beam is positioned at the rear end of the foundation, the upper part of the swinging beam is connected with the swinging beam jack which is arranged on the rear top beam, and the swinging beam can swing in a vertical direction under the action of the swinging beam jack; and the upper and lower parts of the swinging beam jack are connected with the rear top beam and the swinging beam respectively, and the swinging beam is adjusted in a vertical direction under the action of the swinging beam jack. The four-column suspension swinging beam type gangue filling hydraulic support can support a top plate during coal mining, can fill a gob, and integrates support and filling.

Description

technical field [0001] The invention relates to support equipment for comprehensive mechanized coal mining working faces in underground coal mines, in particular to a new hydraulic support integrated with support and filling for goaf filling. Background technique [0002] my country is rich in coal resources, fully mechanized mining equipment is mature, and coal mining technology is becoming more and more perfect. With the shortage of energy, the pace of coal mining in my country is accelerating, and more and more mines are facing the problem of resource depletion. The problem is that my country has liberated the "three-down" coal pressing by adopting traditional strip mining, relocating villages, filling mining and other technical measures to improve the coal recovery rate. However, with the increase of mining depth, the increase of village relocation costs and the improvement of filling technology, filling mining technology has become a trend of vigorous development.
