Embodiment Construction
[0020] As shown in the figure, a drilling, punching and fracturing integrated operation machine for coal mines includes a crawler chassis 1 driven by a power system, a rotating disc 2 arranged on the crawler chassis 1, and a power part 3 that drives a drill pipe 7. The part 3 is slidably arranged on the guide rail 4 through a sliding seat, and the sliding seat is driven to move on the guide rail 4 by the propulsion oil cylinder. The lower part of the guide rail is connected with the fixed slideway 402. 402 moves, and the two ends of the guide rail 4 are respectively provided with cylinder-driven supporting mechanisms 6, which are used to fasten the guide rail 4 in the roadway, and the lower part of the fixed slideway 402 is hinged with the support 8 fixed on the rotating disk 2. The disc 2 is hinged with the lower part of the fixed slideway 402 to be provided with an angle adjustment oil cylinder 5, and the piston rod of the angle adjustment oil cylinder 5 is hinged on the fixe...

The invention discloses a drilling, punching and fracturing all-in-one operation machine for coal mines. A power part is arranged on a guide rail in a sliding mode through a sliding base, the sliding base is driven by a pushing oil cylinder to move on the guide rail, the two ends of the guide rail are respectively provided with a supporting mechanism, the supporting mechanisms are used for tightening and fixing the guide rail in a roadway, the lower portion of the guide rail is hinged to a supporting base fixed to a rotating disk, an angle adjusting oil cylinder is hinged to the position, different from the supporting base, of the rotating disk, and a piston rod of the angle adjusting oil cylinder is hinged to the guide rail so that the guide rail can be pushed to rotate around the supporting base; a drill stem is sleeved with a clamping ring so that pressure borne by the drill stem can be transferred to a front end plate of the guide rail. Due to the fact that hole drilling, hole punching and fracturing are designed to be performed through the all-in-one operation machine, not only is working efficiency greatly improved, but also the drilling range is wide, the rotating disk can rotate within the range of + / - 180 degrees, the angle of the guide rail can be adjusted within the range of 0 degree to 180 degrees so that spherical surface hole distribution can be achieved, and the drilling requirement can be met when the roadway is low.
Description
technical field [0001] The invention relates to equipment used in the field of coal mining, in particular to a drilling, punching and fracturing integrated operation machine for coal mines. Background technique [0002] Because the coal seam often contains gas, in order to ensure production safety, the gas needs to be extracted before mining the coal seam. Generally, a drilling rig is used to drill holes in the coal seam, and then the gas can be extracted before the coal seam can be exploited. However, relying solely on the automatic release of gas is inefficient and difficult to meet production needs. In order to improve the efficiency of gas release, high-pressure water is passed into the drilled hole to fracture the coal seam so that the gas can be released faster. The existing operation process is relatively cumbersome, mostly drilling, punching, and then penetrating the casing and injecting cement slurry to seal the hole, and then injecting high-pressure water for frac...
