Abstract

The invention discloses a circularly self-moving forepoling hydraulic support, which comprises a rail assembly, a supporting beam assembly, a supporting beam assembly moving device and a supporting beam assembly contracting and releasing device, wherein the supporting beam assembly comprises supporting beams, connecting beams, telescopic jacks and upright columns; both ends of the telescopic jacks are respectively hinged on the connecting beams and the supporting beams; the rail assembly is arranged between two upright columns of the supporting beam assembly; the supporting beam assembly moving device comprises a drive, a driving device and a connecting device; the rail assembly comprises rails and rail moving devices arranged on the rails; connecting ends of the connecting devices and the supporting beam assembly are provided with a revolute pair; and the supporting beam assembly contracting and releasing device is arranged on the rails. The circularly self-moving forepoling hydraulic support can support a tunnel roof during coal mining, can further be automatically moved and lifted, and is high in support moving speed.

Description

technical field [0001] The invention relates to comprehensive mechanized coal mining roadway support equipment in underground coal mines, in particular to a circulating self-moving advance support hydraulic support. 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. This also puts forward higher requirements for the movement of the support of the roadway. For example, it is required that the support can be automatically Move the frame to speed up the moving speed and effectively support the roadway. The previous support measures can no longer adapt to the current mining speed, and the safety performance is unstable. In 2009, the applicant applied for a Chinese utility model patent "Self-moving trough advance support bracket" (application date July 13, 2009, authorization ...
