Coal mine underground remote control triangle protective shield

Abstract

The invention relates to a coal mine underground remote control triangle protective shield, which mainly comprises a base, a pushing seat, a hydraulic control mechanism, a front connecting rod, a rear connecting rod, a protective beam, a top beam, a tail beam, side turning beams, an upright post oil cylinder, a connecting shaft, a side turning oil cylinder, a tail beam oil cylinder, a shield adjusting oil cylinder, an anti-falling oil cylinder, a remote control receiving controller and a transmitter. The coal mine underground remote control triangle protective shield remotely controls the oil cylinders to operate so as to complete various functions by taking hydraulic pressure as power. The upright post oil cylinder does the motion of upward supporting inclination. The top beam, the tail beam, a primary side turning beam and a secondary side turning beam are unfolded to form a similar triangle. The coal mine underground remote control triangle protective shield can support a roadway at the end, on the tail part, at the corner and on the edge of the coal mine underground roadway, has an advanced and reasonable design and a compact structure. The top beam can be lifted, unfolded and retracted. The coal mine underground remote control triangle protective shield is suitable for various roadway environments, is accurate and rapid to remotely operate and is safe, stable and reliable.

Description

technical field [0001] The invention relates to a coal mine underground remote-controlled triangular area shielding bracket, which belongs to the technical field of coal mine underground support equipment. Background technique [0002] The relocation of fully-mechanized mining face equipment is an important step to maintain mine production. When the mining is stopped at the stop line, equipment such as coal mining machine, scraper machine and fully-mechanized mining hydraulic support will be withdrawn. When part of the fully-mechanized mining hydraulic support is relocated, The exposed roof between the cover support at the end of the retraction roadway and the fully mechanized mining hydraulic support is called a triangle area, which has become a dead corner and weak area for the support of the underground retraction roadway, burying a safety hazard for the underground retraction equipment.

Problems solved by technology

[0002] The relocation of fully-mechanized mining face equipment is an important step to maintain mine production. When the mining is stopped at the stop line, equipment such as coal mining machine, scraper machine and fully-mechanized mining hydraulic support will be withdrawn. When part of the fully-mechanized mining hydraulic support is relocated, The exposed roof between the cover support at the end of the retracted roadway and the fully mechanized mining hydraulic support is called a triangle area, which becomes a dead corner and weak area for the support of the underground retracted roadway, burying a safety hazard for the underground retracted equipment

[0003] The existing technology uses single hydraulic props and wooden piles to maintain the roof, which wastes a lot of wood and damages the environment. The labor intensity of the workers is high, the safety is poor, the support effect is not ideal, and it cannot meet the requirements of rapid relocation of high-yield and high-efficiency fully mechanized mining faces.

[0004] The triangular area at the end, tail, corner, corner, and edge of the underground roadway has become a dead corner and weak area of ​​the underground roadway, burying safety hazards for the retraction equipment
