Skid-mounted positioning drilling machine underground coal mine

Abstract

The invention discloses a skid-mounted positioning drilling machine underground a coal mine, which comprises a runway, a power head, a runway mounting component, a mounting bracket hydraulic system and a control device, wherein the power head is fixed on the runway; the runway is arranged on the runway mounting component; the runway mounting component is arranged on a mounting bracket, and comprises a bottom board which is fixed on a transverse beam of the mounting bracket, and arranged horizontally; the bottom board is provided with a turnplate which is connected with the runway, and can rotate horizontally; angle scale marks and scale values are arranged on the upper plane of the bottom board; the turnplate is provided with an angle pointer; a runway rotating device used for allowing the runway to rotate in a vertical direction is arranged on the turnplate; a slide rail pair is arranged between the runway rotating device and the runway; and a hydraulic cylinder is connected between the runway and the runway rotating device. Preferably, an inverted-V-shaped auxiliary support for fixing the drilling machine is arranged at the tail end of the runway. The skid-mounted positioning drilling machine has the benefits that angular separation of a drilling hole is accurate in positioning, and the skid-mounted positioning drilling machine is small in size, light in weight, convenient to move and mount, and firm and reliable to mount.

Description

technical field [0001] The invention relates to an underground drilling rig, in particular to an underground skid-mounted positioning drilling rig for coal mines, which is used for accurately constructing roadway moraine head drilling and drill field drilling. Background technique [0002] Coal accounts for 67% of my country's primary energy consumption, and currently 95% of coal mines are underground mining. Among the nearly 600 key mines in China, high-gas mines account for about 50%, making it the country with the most serious coal mine gas in the world. In recent years, with the increase of coal production and the extension of mines to the deep, the number of high-gas and coal and gas outburst mines is increasing, and the amount of coal seam gas emission is increasing. most important factor in production. Establishing a mine gas monitoring and monitoring system, improving the mine ventilation system, and establishing a mine outburst early warning system are all effectiv...
