Description

Technical Field

[0001] This utility model relates to the field of underground construction technology in coal mines, and more specifically, to a mobile gas release hole drilling rig. Background Technology

[0002] With increasing coal mining depth and scale, high-gas-outburst mines are becoming more common. Traditional gas control methods are insufficient to meet the dual demands of efficient mining and safety assurance. Gas release hole technology is an indispensable tool in fully mechanized mining faces. One or more rows of deep holes are drilled into the coal face to release gas from the pre-cut coal seam in advance, reducing gas pressure and content, and preventing sudden large-scale gas outbursts during mining that could lead to coal and gas outbursts.

[0003] Currently, most gas release hole equipment consists of manually operated handheld pneumatic drills. These drills are heavy and cannot be operated by one person alone. Furthermore, the drilling depth is generally around 12 meters, requiring the extension of drill rods, thus necessitating at least three people working together. The operator must also stand inside the scraper conveyor chute to complete the drilling. This manual labor is extremely strenuous and inefficient. Drilling at high points in the coal face is difficult, and serious safety hazards such as coal face collapse and abnormal scraper conveyor startup may occur during construction, potentially causing injury. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a mobile gas release hole drilling rig. This drilling rig reduces manual labor intensity, improves production efficiency, enhances the adaptability of the drilling rig, and eliminates potential safety hazards.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A mobile gas release hole drilling rig includes a traveling assembly, a rotating assembly, a guide rail assembly, a traveling motor, a motor traveling base, and a drilling motor. The rotating assembly is rotatably mounted on the traveling assembly, and its top is connected to the guide rail assembly. The motor traveling base is slidably mounted on the guide rail assembly. The traveling motor is mounted on the motor traveling base and is used to control the movement of the motor traveling base on the guide rail assembly. The drilling motor is horizontally mounted on the motor traveling base and is connected to a coupling.

[0007] The walking assembly includes a walking base plate, outer wheels, inner wheels, and a clamping assembly. The outer wheels and inner wheels are respectively disposed on both sides of the bottom of the walking base plate, and the clamping assembly is disposed on both sides of the bottom of the walking base plate.

[0008] The clamping assembly includes a fixed plate, a clamping plate, a clamping block, a lead screw, and a guide rod. The fixed plate is disposed at the bottom of the traveling base plate. The lead screw is rotatably disposed at the bottom of the traveling base plate. The guide rod is disposed on both sides of the lead screw. One end of the lead screw and the guide rod are both connected to the fixed plate. The lead screw passes through the clamping block and is threadedly connected to the clamping block. One end of the lead screw extending out of the clamping block is connected to a clamping crank. The clamping block has a movable hole corresponding to the guide rod. The clamping plate is fixedly disposed on the side of the clamping block near the fixed plate.

[0009] The outer wheel is a grooved wheel with an arc shape, and the inner wheel is a cylindrical pulley.

[0010] The rotating assembly includes a rotating cylinder, which is rotatably mounted on the walking base plate. The rotating cylinder has multiple positioning holes near its bottom, and the walking base plate is provided with positioning pins that correspond to the positioning holes on the rotating cylinder.

[0011] The guide rail assembly includes a guide rail base plate, guide steel pipes, and a toothed rail. The bottom of the guide rail base plate is hinged to the rotating cylinder. Two sets of guide steel pipes are arranged parallel to each other on the guide rail base plate. The toothed rail is arranged on the guide rail base plate between the two guide steel pipes. The motor travel seat is slidably arranged on the guide steel pipes. A drive gear is provided at the bottom of the travel motor, and the drive gear meshes with the toothed rail.

[0012] The motor travel base is provided with a positioning threaded hole, and a positioning bolt is provided on the positioning threaded hole. The end of the positioning bolt abuts against the guide steel pipe to achieve positioning of the motor travel base.

[0013] The rotating cylinder is provided with an angle adjustment component on its side wall, and the other end of the angle adjustment component is connected to the bottom of the guide rail base plate.

[0014] The angle adjustment assembly includes a telescopic cylinder, a telescopic adjustment rod, and a positioning plug. One end of the telescopic cylinder is hinged to the side wall of the rotating cylinder, one end of the telescopic adjustment rod is inserted into the telescopic cylinder, and the other end of the telescopic adjustment rod is connected to the bottom of the guide rail base plate. Positioning slots are correspondingly provided on the telescopic cylinder and the telescopic adjustment rod. The positioning plug is inserted into the positioning slots on the telescopic cylinder and the telescopic adjustment rod to control the extension amount of the telescopic adjustment rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The drilling rig uses a combination of arc-grooved wheels and cylindrical pulleys to slide directly along the cable trench in the coal mine roadway, eliminating the need for additional track laying or large equipment transportation. This significantly reduces the transfer time between different drilling locations. The clamping assembly design ensures the drilling rig is firmly clamped onto the cable trench during drilling operations, effectively resisting drilling reaction forces, ensuring machine stability and drilling accuracy, and preventing borehole deviation caused by displacement. The travel motor drives the gears to mesh with the toothed rails, driving the motor travel base and drilling motor to automatically and smoothly advance or retreat along the guide steel pipe, achieving automatic feed and withdrawal of the drill rod. This device integrates travel, rotation, clamping, angle adjustment, and automated propulsion designs, combining efficient movement, rapid positioning, stable clamping, flexible angle adjustment, automatic drilling, and rod connection into one drilling rig unit. It significantly improves the efficiency, accuracy, and safety of gas release hole construction while reducing labor intensity, exhibiting strong downhole practicality and adaptability.
