Abstract
Description
Technical Field
[0001] This utility model relates to an angle adjustment device for an anchor drilling and installation machine, specifically an angle adjustment device for an anchor drilling and installation machine used in coal mines, belonging to the technical field of anchor drilling and installation machines. Background Technology
[0002] The anchor bolt drilling machine for coal mines is a key piece of equipment for underground roadway support operations. It is mainly used for drilling and installing anchor bolts. Generally, the drill rod is rotated by a motor, and then the motor is moved by a hydraulic cylinder to perform the drilling.
[0003] However, existing equipment generally suffers from the problem of fixed and non-adjustable drill rod angles. In actual construction, due to the complex and varied rock strata conditions of the roof and sidewalls of underground roadways, it is often necessary to drill anchor bolt holes at different angles according to different support requirements. The fixed angle design makes the equipment unable to adapt to the needs of multi-angle drilling, which seriously affects the flexibility and efficiency of support operations. A large amount of coal and rock dust generated during drilling will quickly spread throughout the entire work area, which not only deteriorates the working environment and affects the health of operators, but also reduces equipment visibility and increases operational risks. Utility Model Content
[0004] The purpose of this utility model is to provide an angle adjustment device for a coal mine anchor drilling machine to solve the above problems. It can not only drill anchor holes at different angles, but also reduce dust during drilling to prevent excessive dust from affecting the working environment.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: an angle adjustment device for a coal mine anchor drill installation machine, comprising a support frame, a drilling structure mounted on the top of the support frame, the drilling structure comprising a rotating frame, a rotating frame rotatably connected to the left side of the top of the support frame, a hydraulic cylinder installed inside the rotating frame, a sliding plate slidably connected to the top of the rotating frame, the output end of the hydraulic cylinder being fixedly connected to the bottom end of the sliding plate, a motor mounted on the top of the sliding plate, a dust suppression structure mounted on the rotating frame, the dust suppression structure comprising a fixed seat, a fixed seat fixedly connected to the left side of the top of the rotating frame, a water inlet groove provided inside the fixed seat, the water inlet groove being connected to an external high-pressure water outlet device, a high-pressure nozzle fixedly connected to the left side of the fixed seat, a slider slidably connected inside the fixed seat, and a plug rod fixedly connected to the left side of the slider.

[0009] Preferably, pulleys are rotatably connected to both sides of the skateboard, and grooves are provided on both sides of the rotating frame, with the pulleys and grooves being slidably connected.
[0010] Preferably, a slide block is fixedly connected to the top right side of the rotating frame, and a slide rod is fixedly connected to the right side of the slide plate, with the slide block and the slide rod being slidably connected.
[0011] Preferably, an abutment rod is fixedly connected to the other side of the slide rod, and the abutment rod abuts against the slide block.

[0024] As a technical optimization of this utility model, a guide rod 306 is fixedly connected to the other side of the slider 304. The guide rod 306 is slidably connected to the fixed seat 301, and the guide rod 306 can guide the slide plate 203.
[0025] As a technical optimization of this utility model, a spring 307 is fixedly connected to the slider 304, and the other end of the spring 307 is fixedly connected to the fixed seat 301. A connecting ring 308 is fixedly connected to the other side of the guide rod 306, and a connecting frame 309 is fixedly connected to the bottom end of the connecting ring 308. A connecting rod 310 is fixedly connected to the connecting frame 309, and a contact plate 311 is fixedly connected to the other end of the connecting rod 310. The spring 307 can drive the slider 304 to reset after the contact plate 311 and the slide plate 203 are separated, so that the insertion rod 305 and the high-pressure nozzle 303 are separated.
[0026] As a technical optimization of this utility model, both sides of the slide plate 203 are rotatably connected with pulleys 205, and both sides of the rotating frame 201 are provided with sliding grooves 206. The pulleys 205 and sliding grooves 206 are slidably connected, so that the slide plate 203 can slide on the rotating frame 201 through the pulleys 205 and sliding grooves 206.
[0027] As a technical optimization of this utility model, a slide block 207 is fixedly connected to the right side of the top of the rotating frame 201, and a slide rod 208 is fixedly connected to the right side of the slide plate 203. The slide block 207 and the slide rod 208 are slidably connected, and the slide plate 203 can be guided by the slide rod 208 and the slide block 207.
[0028] As a technical optimization of this utility model, an abutment rod 209 is fixedly connected to the other side of the slide rod 208. The abutment rod 209 abuts against the slide block 207, and the slide plate 203 can be limited by the abutment rod 209.
[0029] As a technical optimization of this utility model, an adjustment structure 4 is installed on the support frame 1 and the rotating frame 201. The adjustment structure 4 includes a fixed rod 401. The fixed rod 401 is fixedly connected to the bottom right side of the rotating frame 201. The fixed rod 401 has a fixed groove 402 inside. The top right side of the support frame 1 is fixedly connected to a fixed column 403. The fixed column 403 and the fixed groove 402 are slidably connected. The fixed groove 402 is generally arc-shaped. The fixed column 403 is generally cylindrical. A screw 404 is fixedly connected to the fixed column 403. A fixing nut 405 is threadedly connected to the screw 404. The fixing nut 405 and the fixed rod 401 are in contact. When the fixing nut 405 is rotated, and the fixing nut 405 and the fixed rod 401 are no longer in contact, the angle of the rotating frame 201 can be adjusted through the fixing groove 402 and the fixing column 403 inside the fixed rod 401.
[0030] In use, when installing an anchor drill, the support frame 1 is installed at the drilling location. Then, the fixing nut 405 is rotated. Once the fixing nut 405 and the fixing rod 401 are no longer in contact, the angle of the rotating frame 201 can be adjusted via the fixing groove 402 and fixing column 403 within the fixing rod 401. After adjustment, the fixing nut 405 is rotated in the opposite direction, causing the fixing nut 405 and fixing rod 401 to re-engage, thus fixing the adjusted rotating frame 201. The drill rod is then installed at the output end of the motor 204. Starting the motor 204 activates the hydraulic cylinder 202, which drives the sliding plate 203 to slide on the top of the rotating frame 201. This allows the motor 204 to slide for drilling. The pulley 205 and sliding groove 206 facilitate the sliding of the sliding plate 203 on the rotating frame 201. The sliding rod 208 and sliding seat 207 guide the sliding plate 203, while the contact rod 20... 9 can limit the sliding plate 203. When drilling, external water supply enters the water inlet 302 inside the fixed base 301. Therefore, multiple high-pressure nozzles 303 spray water in a ring to reduce the dust generated during drilling. When it is necessary to increase the number of drill rods, the reverse start hydraulic cylinder 202 can drive the sliding plate 203 to slide in the opposite direction. Therefore, when the bottom end of the sliding plate 203 contacts the contact plate 311, the connecting rod 310 and the connecting frame 309 drive the connecting ring 308 to slide on the side of the fixed base 301, thereby driving the insertion rod 305 to slide. When the insertion rod 305 contacts the high-pressure nozzle 303, the water spray can be stopped to facilitate the addition of drill rods. The guide rod 306 can guide the sliding plate 203. The spring 307 can drive the slider 304 to reset after the contact plate 311 and the sliding plate 203 are separated, so that the insertion rod 305 and the high-pressure nozzle 303 can be separated, thereby enabling dust reduction when working again.
