Wheel type truck-mounted drilling rig

Abstract

The invention discloses a wheel type truck-mounted drilling rig which is characterized in that a movable frame with a drilling device is disposed on a body, the body comprises a mining flatbed truck and a hydraulic winch, a support seat is disposed on the mining flatbed truck, a support beam which is used for allowing the movable frame to be horizontal is disposed on the support seat, a guide rail clamp is further disposed on the mining flatbed truck, the movable frame comprises a #-shaped frame, two ends of the two crossbeams of the #-shaped frame are fixedly connected with main support oil cylinders, two longitudinal beams of the #-shaped frame forms two parallel guide rails which are in slide fit with a movable support, the movable support is hinged to the outer end of the support beam, a vertical oil cylinder which is used for allowing the movable frame to be vertical is connected between the movable support and the support seat, an n-shaped frame is fixedly connected between cylinder bodies the two main support oil cylinders, and a drilling rig turn plate is disposed between the n-shaped frame and the drilling device. The wheel type truck-mounted drilling rig has the advantages that the wheel type truck-mounted drilling rig can be moved in a tunnel without damaging sleepers, the drilling rig is good in rigidity, and drilling hole positions can be adjusted conveniently.

Description

technical field [0001] The invention relates to a drilling rig for underground drilling, in particular to a drilling rig for drilling through layers of special gas roadways and drilling along layers of coal roadways in roadways with rails. 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 mine gas monitoring and monitoring systems, improving mine ventilation systems, and establishing mine outburst early warning systems are all powerful measures for mine gas con...

Problems solved by technology

However, due to the large size and heavy weight of the crawler drilling rig, the sleeper of the track in the tunnel will be crushed during the moving process in the tunnel. At the same time, when used in a gas tunnel with a large inclination angle, its self-stability will be affected by the sliding component of gravity. Therefore, it is not suitable for use in gas lanes with large inclination angles
