Coal Mine Tunnel Large Gas Drainage Crawler Drilling Rig

Abstract

The invention discloses a large mining height gas extracting caterpillar drill for a coal mine gallery. The large mining height gas extracting caterpillar drill at least comprises a body and a shift drilling device, wherein the body comprises a caterpillar body; two sides of the lower end of the caterpillar body are respectively provided with a caterpillar assembly; the shift drilling device is arranged at the front end of the caterpillar body and comprises a vehicle body connecting plate, a tail end connecting plate, a telescopic amplitude changing device, an orientation adjusting device, a dip angle adjusting device and a feeding device; one end of the telescopic amplitude changing device is connected to the vehicle body connecting plate, and the other end of the telescopic amplitude changing device is connected to the tail end connecting plate; the telescopic amplitude changing device ensures that the tail end connecting plate integrally parallelly moves in a plane relative to the vehicle body connecting plate; therefore, the large mining height gas extracting caterpillar drill is wide in drilling height range, and has the characteristic of wide range for adjusting the height of a center hole of the drill; in crossheading construction for a working face in tunneling, a construction range is wide, the whole working face can be involved, and the drill has obvious advantages in large mining height gas extraction drilling.

Description

technical field [0001] The invention belongs to the technical field of large mining height and multi-layer gas drainage drilling in underground coal mines, and in particular relates to a large mining height gas drainage crawler drill capable of quickly adjusting azimuth angle and inclination angle in coal mine tunnels. Background technique [0002] In the thick coal seam and large mining height mining technology, the maximum mining height is 5.5 meters. At the same time, the same working face often has the problem of solving both high hole gas drainage and low gas drainage. Therefore, Under such a special mining condition, the bedding gas drainage in the mining face and the gas drainage of the front exploration hole put forward new requirements for the development of the drilling rig. [0003] When the current existing drilling rigs are used for mining in this environment, due to the small height adjustment range, a drilling rig support frame is required for high-level drill...

AI Technical Summary

Problems solved by technology

[0003] When the current existing drilling rigs are used for mining in this environment, due to the small height adjustment range, a drilling rig support frame is required for high-level drilling, which is difficult to fully meet the construction requirements of high and low multi-layer holes. Low, narrow scope of application, and large dimensions, small azimuth and inclination adjustment range
