Abstract

The invention relates to a trestle type drilling machine, comprising a hydraulic motor and a drill pipe arranged at the front end thereof; wherein the tip of the drill pipe is assembled with corresponding drill head, the hydraulic motor is fixed on a guide rail sliding seat, the guide rail sliding seat and a guide rail on a beam column type bracket beam are in sliding fit, the bracket beam is arranged on a telescopic upright, the front end of the bracket beam is provided with a positioning mechanism stretching along the feed direction of drilling, and the rear end of the bracket beam is provided with an advancing mechanism capable of driving the guide rail sliding seat to move forward and backward. The invention can realize that the entire rack is stably positioned by reliably against a roadway in up, down and front directions, supporting of the drilling machine is ensured to be stable and reliable when in operation, as the bracket beam is arranged on the telescopic upright and the telescopic positioning mechanism is arranged in drilling and feed directions, the upright and positioning mechanism all can be telescopic, thus being convenient for carrying and adjusting position, space occupied by the entire equipment is ensured to be small, and the concrete environment of small operation space in the roadway can be met.

Description

technical field [0001] The invention relates to a column drilling rig. Specifically, the emulsion with a certain working pressure is used as the power to push the oil cylinder for drilling feed, drive the hydraulic motor to drive the rotary mechanism, transmit the torque to the drill pipe, and the drill bit rotates and drills and breaks. Rock, water supply in the center of the output shaft, can be used for wet drilling to break rock. Background technique [0002] In the prior art, there is a hydraulic motor powered by an emulsion with a certain working pressure, and the hydraulic motor is used to drive the drill rod to drive the drill bit to perform rotary drilling and rock breaking. The hydraulic motor is usually fixed on a frame, how to fix the frame well and how to adjust the angle of the drill pipe for drilling at different stations are all technical problems that have not been effectively solved at present. Contents of the invention [0003] The object of the present...
