Problems solved by technology

Restricted by terrain conditions, the drilling angle for construction release is mostly -30° or +30°. During the construction of the discharge hole, it is difficult, requires many personnel, and insufficient propulsion force
Moreover, once the problem of drill sticking is encountered, even if multiple people hold the drill together, they cannot fully control the drill
Therefore, when the drill is stuck, it will cause the drilling machine to collapse and injure the personnel.

Abstract

The invention relates to a runway type pneumatic drilling machine. The runway type pneumatic drilling machine comprises a pneumatic drilling machine body. The pneumatic drilling machine body and a drilling machine runway are connected in a circumferentially fixed and axially sliding mode. The pneumatic drilling machine body is further connected with a pushing cylinder mounted on the drilling machine runway. The drilling machine runway is mounted on a strut. Through the runway type pneumatic drilling machine, the production accidents that rotation of the drilling machine threatens the personal safety can be avoided.

Description

technical field [0001] The invention belongs to the technical field of coal mining, in particular to a track-type pneumatic drilling machine. Background technique [0002] For high-gas mines, the coal seam to be mined has outstanding hazards, and local discharge boreholes need to be constructed during roadway excavation. Pneumatic hand-held drilling rigs are used during partial discharge drilling, and mine pressure air is used as the power source for the drilling rig. Restricted by terrain conditions, the drilling angle for construction release is mostly -30° or +30°. During the construction of the discharge hole, it is difficult and requires many personnel and insufficient propulsion. Moreover, once the problem of drill sticking is encountered, even if multiple people hold the drill together, they cannot fully control the drill. Therefore, when the drill is stuck, the drilling rig will collapse and the personnel will be injured. Contents of the invention [0003] In or...
