Coal mine roadway rapid tunneling auxiliary device

Abstract

The invention belongs to the technical field of coal mine excavation, and particularly relates to a coal mine roadway rapid tunneling auxiliary device. Aiming at solving the technical problems that atunneling machine is small in excavation crushing area and slow in progress during coal mine excavation, the following scheme is put forward currently, the coal mine roadway rapid tunneling auxiliarydevice comprises a base plate, a base is fixed to the outer wall of the top of the base plate, a third telescopic rod is fixed to the inner wall of the rear side of the base, and a toothed plate is fixed to the top end of the third telescopic rod. According to the coal mine roadway rapid tunneling auxiliary device, through arrangement of the third telescopic rod, the toothed plate, a rotating rodand a toothed disc, the third telescopic rod extends and retracts, the toothed plate moves forwards and backwards, thus the toothed disc and the rotating rod are made to rotate leftwards and rightwards, and therefore the transverse direction of drill bit excavation is controlled; and through arrangement of a second connecting rod, a first connecting rod, a second telescopic rod and a first telescopic rod, the second telescopic rod and the first telescopic rod are telescopically matched to enable the drill bit to move up and down, so that the longitudinal excavation direction of the drill bit is controlled, through cooperation, coal mine excavation work of the coal mine roadway rapid tunneling auxiliary device is facilitated, and the coal mine excavation work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coal mine excavation, in particular to an auxiliary device for rapid excavation of coal mine roadways. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines include large areas above and below ground and associated facilities. A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal, usual...

[0003] The Chinese invention patent with the application number of 201910296749.8 discloses a coal mine roadway rapid driving auxiliary device, including a moving seat, a coal mining mechanism, a coal collection mechanism and a control room. The moving seat has a vertical cylindrical support block for coal mining. The mechanism is installed on the upper end of the cylindrical support block, the coal collection mechanism is rotatably installed on the upper cylindrical support block, and the control room is installed on the coal mining mechanism. The coal mining mechanism includes a base fixed on the upper end of the cylindrical support block, and the base The left end of the seat is provided with a placement groove, and the top surfaces of the left and right ends of the base are respectively fixed with two left fixed blocks and two right fixed blocks, and the left sides of the two right fixed blocks are fixed with horizontal main hydraulic cylinders. A connection plate is fixedly connected between the piston rods of the two main hydraulic cylinders, the left end of the connection plate penetrates into the placement groove and is embedded with a coal mining motor, and the output shaft of the coal mining motor is connected with a fixed shaft , and the fixed shaft is fixed with a coal scraper along the circumferential direction. The above-mentioned device drills and crushes the coal seam through the drill bit, but the device can only work in a straight line, and cannot quickly excavate a large area, and the work efficiency is low
