Improved single-track pneumatic drill carriage device

Abstract

The invention discloses an improved single-track pneumatic drill carriage device. The improved single-track pneumatic drill carriage device comprises a drill carriage chassis. A drilling actuating mechanism is arranged on the drill carriage chassis. The drill carriage chassis comprises a frame, a track frame is arranged on the frame and sleeved with the track, and thrust wheels are arranged on the inner side of the track; the drilling actuating mechanism comprises a guide rail, a rotary mechanism is arranged on the guide rail, the guide rail is fixed to a boosting air cylinder, and a silencer is arranged at the exhaust end of the rotary mechanism. The defects in the prior art can be overcome, and the improved single-track pneumatic drill carriage device is suitable for operation in a narrow roadway.

Description

technical field [0001] The invention relates to a drilling device for roadway development, in particular to an improved single-track pneumatic drilling device. Background technique [0002] Gas explosions occur frequently in my country's coal mines, resulting in a large number of deaths. Gas accidents are the biggest threat to coal mine production. Mining coalbed methane before mining coal is beneficial to fundamentally prevent coal mine gas accidents. At present, most of the drilling rigs or drilling rigs used in my country's coal mines for water exploration and gas exploration, drainage and gas drainage use electric motors as power sources, and are equipped with power supplies, cables, comprehensive protection devices and other series of power supply systems that may cause grounding, short circuits, and arcing. Such as electromechanical accidents, thus affecting the normal work of electric drilling rigs or hydraulic drilling rigs, and affecting safe production. In additio...

AI Technical Summary

Problems solved by technology

At present, most of the drilling rigs or drilling rigs used in my country's coal mines for water exploration and gas exploration, drainage and gas drainage use electric motors as power sources, and are equipped with power supplies, cables, comprehensive protection devices and other series of power supply systems that may cause grounding, short circuits, and arcing. Electromechanical accidents, which affect the normal work of electric drilling rigs or hydraulic drilling rigs, and affect production safety

In addition, when using electric or hydraulic drilling rigs, due to the repeated dragging of the power supply cable on the tunneling head of the working face, it may cause detonation phenomena such as wire nozzle movement and cable breaches. For high-gas mines, a major hidden danger is virtually buried

Secondly, the environment under the mine is complex and harsh. In many cases, due to the limitation of the width of the roadway, the double-crawler drilling rig cannot pass smoothly, and other measures must be taken to complete the drilling operation, which reduces work efficiency.
