Problems solved by technology

[0002] When the bottom surface of coal mine roadway protrudes, it will cause track deformation and affect the operation of electric locomotives. In serious cases, it will cause train derailment and cause accidents. serious injury
Because the bottom plate of the roadway is rock, the hardness is relatively high, the labor intensity of manual undercover is high, time-consuming and laborious, and the productivity is extremely low
The roadway cannot be transported during undercover construction, and a roadway is artificially undercover, which takes a long time, which will seriously affect the normal production of the mine, and even cause partial or complete shutdown of the mine. Mechanized undercover equipment is imperative

Abstract

The invention discloses an underground roadway dinting device, which comprises a walking part and a cutting part hinged with the walking part, wherein the cutting part comprises a rocker arm hinged on an upper support frame of the walking part, the rocker arm realizes the transverse swinging operation through a swinging hydraulic cylinder arranged in the upper support frame, a height regulating hydraulic cylinder is hinged between the middle part of the upper end of the rocker arm and the upper support frame of the walking part, the height regulating hydraulic cylinder drives the rocker arm to realize the longitudinal height regulating operation, the top end of the rocker arm is provided with a cutting rolling tube, the cutting rolling tube is driven through a rolling tube transmission system and a hydraulic motor arranged at one side of the cutting rolling tube, the rotary operation at the top end of the rocker arm is realized, and cutting knives are uniformly distributed on the surface of the cutting rolling tube. The structure of the underground roadway dinting device is compact, the layout is reasonable, the rocker arm with the cutting part can be conveniently regulated in any position, the operation is simple, the application range is wide, and meanwhile, the walking part is designed, so the device has the advantages that the moving is convenient, and the moving along with the work surface can be realized.

Description

technical field [0001] The invention relates to a coal mine roadway trimming machine, in particular to an undercover device for clearing roadblocks and re-laying tracks when the bottom surface of the mine roadway is convex and causes rail deformation. Background technique [0002] When the bottom surface of coal mine roadway protrudes, it will cause track deformation and affect the operation of electric locomotives. In serious cases, it will cause train derailment and cause accidents. serious injury. Because the bottom plate of the roadway is rock, the hardness is relatively high, and the manual undercover work is labor-intensive, time-consuming and labor-intensive, and the productivity is extremely low. The roadway cannot be transported during undercover construction, and a roadway is artificially undercover, which takes a long time, which will seriously affect the normal production of the mine, and even cause partial or complete shutdown of the mine. Therefore, it is nece...
