Abstract

The invention relates to a remote-controlled pulley-type shielding bracket under a coal mine, structurally comprising a base, a hydraulic control mechanism, a top beam, a lateral protection plate, a shielding beam, an upright post cylinder, a front connecting rod, a rear connecting rod, a lever shaft, a drawing pulley, a drawing ring remote-controlled receiving controller and an emitter. Aiming at the retracement and removal of original equipment and bracket after gob underground, transition is supported; the lifting supporting design of a two-column upright post cylinder is adopted, lateral shielding plates are respectively arranged at both sides of the top beam, a drawing seat and the drawing pulley are arranged at the front of the top beam, and the whole power is hydraulically controlled, and remote control is adopted for emission and receiving operations. The bracket has the advantages of advanced and reasonable design, compact structure, safety, stability, reliability and convenience of operation use and is an ideal remote-controlled pulley-type shielding bracket for retracement.

Description

technical field [0001] The invention relates to an underground remote control pulley type shield support in coal mine, which belongs to the technical field of underground support equipment in coal mine. Background technique [0002] The relocation of fully-mechanized mining face equipment is an important step to maintain mine production. When mining back to the stop line, equipment such as coal shearers, scraper machines, and fully-mechanized mining hydraulic supports need to be relocated from one working face to the next to be mined face. Installation, the traditional relocation uses single hydraulic props, I-beams and wooden piles to maintain the roof. This support method is time-consuming and labor-intensive, labor-intensive, wastes wood, and supports height, support speed, degree of automation, operability, and safety. They cannot adapt to the requirements of rapid relocation of high-yield and high-efficiency fully mechanized mining face. [0003] In the process of with...
