Manned device suitable for coal mine thin seam fully mechanized coal mining face

Abstract

The invention provides a manned device suitable for a coal mine thin seam fully mechanized coal mining face. The manned device comprises a guide rail laid along a conveyor cable frame, a driving device, driving pulleys, a manned bin body and an adjustable pulley. The rail surface of the guide rail comprises a left side surface and a right side surface, the rail surface of the guide rail is a groove-shaped rail surface, the driving pulleys comprise a left pulley and a right pulley, the left pulley and the right pulley are clamped on the groove-shaped rail surface of the guide rail in a clamping type rolling manner, and the driving device drives the left pulley and the right pulley to rotate; and the upper end of the back face of the manned bin body is hinged to the driving device, the adjustable pulley comprises a pulley body, a wheel carrier and a telescopic rod, the tail end of the telescopic rod is connected to the lower portion of the back face of the manned bin body, the front end of the telescopic rod is connected with the wheel carrier, the pulley body is installed on the wheel carrier, and the wheel face of the adjustable pulley body faces a frame body of the conveyor cable frame. According to the manned device, maintainers can walk far enough along the guide rail, limitation is greatly reduced, meanwhile, the riding angle can be adjusted, and safety is high.

Description

technical field [0001] The invention relates to the field of coal mines, in particular to a man-carrying device suitable for fully mechanized mining working faces of thin coal seams in coal mines. Background technique [0002] In my country, thin coal seam resources are abundant and widely distributed. Among the proven mining areas, 84% of the mining areas have thin coal seams, with a total reserve of about 62 billion tons, accounting for about 20% of my country's total reserves, while the output only accounts for 7% of the total output. %, which is far lower than the proportion of reserves. In recent years, intelligent mining of thin coal seams has been a research hotspot. [0003] Due to the narrow space, the thin coal seam working face is difficult for personnel to operate and patrol. It is the system with the most equipment, the worst environment and the most complicated work in coal mine production. It has always been a subject of vigorous research by various countries. ...

Problems solved by technology

[0004] At present, there is no good technology and equipment for personnel transportation in the thin coal seam working face. It is very inconvenient for operators, inspectors, and maintenance personnel to walk in the thin coal seam working face. They need to bend over or even crawl forward for a long time. Supports, conveyors, shearers and many other equipment are very laborious to move forward. It is urgent to study related thin coal seam manned devices to provide convenience for underground personnel to move and improve the mining efficiency of the working face.

[0005] Patent 201210275358.6 (a manned warehouse for a thin coal seam shearer) discloses a manned warehouse for a thin coal seam shearer. By installing a connecting rod on the shearer to articulate the manned warehouse, the warehouse body follows the movement of the shearer. It solves the problem of the movement of the shearer driver during mining, but when the personnel need to go to other locations for operation and inspection, or when the working face equipment is shut down for maintenance, the movement of the maintenance personnel cannot be realized, which limits its application in the mine
