Problems solved by technology

[0002] At present, the deep hole drilling rigs used in coal mine roadways mainly use electric or hydraulic oil as the power source. All equipment in coal mine roadways must be explosion-proof, so the equipment must be equipped with explosion-proof motors. Due to its complex structure, it is inconvenient to carry and use.
In addition, most of the drill pipe sleeves of existing drilling rigs are integral, which requires a large space for installation and use, which is time-consuming and labor-intensive

Abstract

A pneumatic post drill is composed of a mainframe, a control console and a muffler through a flexible rubber hose. The pneumatic post drill which is a portable drill has the advantages of safety, explosion protection, high torque, high rotating speed, light weight, small size, high efficiency, simple structure, convenience in maintenance and the like. Therefore, the pneumatic post drill is high in working efficiency, good in support quality, low in labor intensity of workers, less in drilling footage cost and suitable for market promotion; the parts of the drill are connected through the flexible rubber hose, flexible arrangement on different downhole sites is facilitated, and the mainframe can be further disassembled when transportation conditions are poor. The drill is mainly applied to coal mines with coal and gas outburst and explosion risk, and can also be used for geologic structure coal seam exploration, water exploration, gas exploration, coal seam water injection and pressure hole relief as well as drilling of roadway side anchor bolt holes, stirring of anchor bolts and mounting of nuts. The drill can be further used for stirring of rock roadway resin anchor bolts and mounting of bolts, and is one of necessary devices in the coal mining industry.

Description

technical field [0001] The invention relates to a pneumatic column drilling machine. Background technique [0002] At present, the deep hole drilling rigs used in coal mine roadways mainly use electric or hydraulic oil as the power source. All equipment in coal mine roadways must be explosion-proof, so the equipment must be equipped with explosion-proof motors. Due to its complex structure, it is inconvenient to carry and use. In addition, most of the drill pipe sleeves of the existing drilling rigs are integral, which requires a large space for installation and use, which is time-consuming and labor-intensive. Coal roadway bolt support has very prominent advantages in improving the support effect, reducing the support cost, speeding up the speed of roadway formation, reducing auxiliary transportation volume, reducing labor intensity, and improving the utilization rate of the roadway section. Coal-producing countries generally attach importance to it and adopt it competiti...
