Drilling device for mine tunnel and with function of conveniently adjusting position and angle

Abstract

The invention discloses a drilling device for a mine tunnel and with the function of conveniently adjusting the position and the angle. The drilling device comprises a base. Track wheels are fixedly mounted on the lower surface of the base through brackets. A first motor is fixedly mounted in an inner cavity of a motor box, an output shaft of the first motor penetrates through the motor box and then is fixedly connected with the cylinder bottom of a first hydraulic cylinder, and a supporting plate is arranged on the upper side of the first hydraulic cylinder. A supporting rod is fixedly weldedto the lower surface of the supporting plate, and a mounting plate is arranged at the right end of the upper surface of the supporting plate. A second motor is arranged on the upper surface of the supporting plate through a second sliding mechanism, and a drilling bit is fixedly mounted at the output end of the second motor. An angle adjusting mechanism comprises a servo electric cylinder, a connecting rod, a first hinging lug and a second hinging lug. According to the drilling device, the position and the orienting angle of a drilling bit are conveniently adjusted, drilling work of multipleposition and multiple stations can be rapidly conducted, the drilling device can move on a rail in the mine tunnel conveniently, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for coal mines, and in particular relates to a drilling device for mine tunnels which is convenient for adjusting the position and angle. 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 dig underground to mine coal, 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. [0003] The vast majority of coal mines in my country belong to underground coal mines. It is necessary to dig mine roads to mine coal. It is necessary to install lamps or brackets and other related equipment on the mine roads, so i...
