An automatic loading and unloading drill pipe device for a soft coal seam gas drilling rig and its application method

Abstract

The invention discloses a device for automatically loading and unloading drill pipes of a soft coal seam gas drilling rig and a method for using the device. There are hydraulic jacking columns around; the feeding device is provided in the middle of the upper surface of the frame, including guide rails and feeding hydraulic cylinders; the hydraulic power source device is installed at the side and rear of the frame, including motor pumps, oil tanks, and crawler belts at the bottom of the frame device, the auxiliary clamping and positioning device is fixed in the middle of the front power head and the rear power head. The device can automatically connect the next helical drill pipe without stopping the drilling, avoiding the accident of holding (clamping) the drill pipe because the coal powder cannot be continuously discharged and the coal powder is accumulated due to the need to stop the drill for manual connection of the drill pipe.

Description

technical field [0001] The invention relates to an automatic loading and unloading drill pipe device for a soft coal seam gas drilling rig and a use method thereof, belonging to the field of mining machinery. Background technique [0002] At present, gas drilling rigs in soft coal seams have always been a research hotspot in the field of mining machinery in my country. During the drilling process of many domestic drilling rigs, when the next auger drill pipe is connected, the long drill pipe that has been drilled into the coal seam needs to stop rotating, resulting in the drilling. The drill pipe part of the coal seam is frequently started and stopped, and the coal slag in the coal hole cannot be discharged continuously, resulting in the accumulation of coal powder inside the drill hole. The rod is locked and cannot be started. In severe cases, the drill rod will break, the drill rod will be lost, and the drill hole will not be able to be used. Such safety accidents will bring...

[0002] At present, gas drilling rigs in soft coal seams have always been a research hotspot in the field of mining machinery in my country. During the drilling process of many domestic drilling rigs, when the next auger drill pipe is connected, the long drill pipe that has been drilled into the coal seam needs to stop rotating, resulting in the drilling. The drill pipe part of the coal seam is frequently started and stopped, and the coal slag in the coal hole cannot be discharged continuously, resulting in the accumulation of coal powder inside the drill hole. The rod is locked and cannot be started. In severe cases, the drill rod will break, the drill rod will be lost, and the drill hole will not be able to be used and other safety accidents, resulting in huge economic losses.
