Technical Field
[0001] This utility model relates to the field of equipment technology for the exploration and development of mineral resources, and in particular to a special pipe-laying device for roof gas drilling. Background Technology
[0002] The ZYW-3200 fully hydraulic tunnel drilling rig is a drilling equipment used in underground coal mines and other similar scenarios. It is mainly used for drilling gas drainage holes, grouting fire prevention and extinguishing holes, coal seam water injection holes, etc. It is mainly composed of components such as oil tank, operating platform, electric motor assembly, power head, frame, tracked vehicle, anchor support and tilt adjustment system, clamp, cooler assembly, pipe lowering device and drilling tools. The front of the drilling rig has a large-stroke clamp that can effectively hold the PVC sealing pipe. However, in field practice, due to the large drilling angle of the PVC sealing pipe, the hydraulic chuck of the drilling rig could not clamp the φ73mm drill rod tightly because the outer diameter radius of the φ63mm PVC sealing pipe differed by 5mm. This posed a risk of the sealing pipe slipping down and injuring people, and manual pipe lowering was inefficient.
[0003] Therefore, this utility model proposes a special pipe-laying device for roof gas drilling to solve the problems existing in the prior art. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a special pipe-lowering device for roof gas drilling to solve the problems in existing technologies where, during field practice, the large drilling angle of the lowered PVC sealing pipe makes it impossible to clamp the sealing pipe, posing a risk of the sealing pipe sliding down and injuring people, and the low efficiency of manual pipe lowering.
[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a special pipe-laying device for roof gas drilling, including a main gasket, a conical gasket fixedly installed on the front side of the main gasket, an installation frame fixedly installed on the side wall of the main gasket, a first bolt passing through the inner side of the installation frame and threadedly connected thereto, a clamping assembly provided on the inner side of the main gasket for clamping the sealing pipe, and a sliding limiting assembly on the inner side of the installation frame for increasing the stability of the device.
[0006] Further improvements include: the tapered gasket adopts a wedge-shaped design at the front, with a wedge portion of approximately 30mm; and the main gasket, tapered gasket, and mounting bracket are integrated into a single unit.
[0007] A further improvement is that the clamping assembly includes a mounting block, a clamping member is fixedly mounted on the side of the mounting block away from the mounting frame, a clamping groove is provided on the side of the clamping member away from the mounting block, and a first mounting port and a second mounting port adapted to the mounting block and the clamping member are provided on the inner side of the main gasket.
[0008] A further improvement is that multiple locking blocks are fixedly installed on the surface of the mounting block and at the top and bottom of the clamping member, and a slot adapted to the locking blocks is opened on the inner side of the main pad.
[0009] A further improvement is that the limiting component includes a connecting frame, the inner side of the mounting frame is provided with a connecting groove for the connecting frame to slide left and right, the inner side of the connecting frame is provided with a plurality of threaded holes adapted to the first bolt, and the connecting frame is provided with a second bolt through it and threadedly connected to it.
[0010] A further improvement is that a protective block is fixedly installed on the inner side wall of the connecting frame, the front side of the protective block is at the same level as the front side of the mounting frame, and a connecting hole is provided on the inner side of the connecting frame for the second bolt to pass through.
[0011] The beneficial effects of this utility model are as follows: 1. The independent clamping components specifically address the radius difference issue between the φ73mm drill rod and the φ63mm sealing pipe. Combined with the double locking of the clamping block and the slot, as well as the anti-slip design of the wedge structure, the clamping force of the sealing pipe is effectively improved, eliminating the risk of downward slippage and injury. The clamping components are easy to assemble and disassemble, facilitating installation and replacement by workers and ensuring the clamping effect of the device. The sliding adaptation design of the connecting frame is compatible with different drilling rig chucks, increasing the practicality of the device. Attached Figure Description

Detailed Implementation
[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0018] according to Figure 1-4 As shown, this embodiment proposes a solution: a special pipe-laying device for roof gas drilling, including a main gasket 1, a conical gasket 2 fixedly installed on the front side of the main gasket 1, a mounting bracket 3 fixedly installed on the side wall of the main gasket 1, a first bolt 4 passing through the inner side of the mounting bracket 3 and threadedly connected thereto, a clamping assembly provided on the inner side of the main gasket 1 for clamping the sealing pipe, and a sliding limiting assembly on the inner side of the mounting bracket 3 for increasing the stability of the device.
[0019] In this implementation case, during use, the conical shim 2 and the main shim 1 are inserted into the through hole of the hydraulic chuck of the drilling rig. The device is symmetrically fixed to the front end cover of the drilling rig chuck 17 by the first bolt 4. After the chuck moves the device and clamps the sealing pipe, the sealing pipe is lowered into the hole by the drilling rig. Through the setting of the independent clamping component, the φ63mm sealing pipe 16 is effectively clamped, eliminating the risk of the sealing pipe falling down and injuring people. The clamping component is easy to install and disassemble, making it convenient for workers to install and replace it, increasing the clamping effect of the device. Through the function of the connecting component, the device is more stably installed on the chuck surface. At the same time, the device is adapted to chucks of different sizes, increasing the practicality of the device.
[0020] The tapered gasket 2 features a wedge-shaped design at the front, with a wedge portion of approximately 30mm. The main gasket 1, tapered gasket 2, and mounting bracket 3 are integrated into one unit. This integrated structure reduces the gap between components, enhances overall strength, and reduces the risk of device deformation when drilling at large angles. The 30mm wedge design enhances compatibility with drilling and sealing pipes, effectively counteracting the downward force generated by the sealing pipe due to the angle.
[0021] The clamping assembly includes a mounting block 6. A clamping component 7 is fixedly installed on the side of the mounting block 6 away from the mounting frame 3. A clamping groove is formed on the side of the clamping component 7 away from the mounting block 6. A first mounting port 8 and a second mounting port 9 are formed on the inner side of the main gasket 1, which are adapted to the mounting block 6 and the clamping component 7. The mounting block 6 is embedded into the first mounting port 8 of the main gasket 1, and the clamping component 7 corresponds to the second mounting port 9. When the main gasket 1 is fixedly installed with the chuck, the mounting block 6 is effectively prevented from falling off. The PVC sealing tube is clamped into the clamping groove, and the sealing tube is clamped by friction and structural locking force. The independent clamping assembly can effectively clamp the φ63mm sealing tube 16, eliminate the risk of the sealing tube falling down and injuring people, and the clamping assembly is easy to install and disassemble, making it convenient for workers to install and replace it, and ensuring the clamping effect of the device.
[0022] Multiple locking blocks 10 are fixedly installed on the surface of the mounting block 6 and at the top and bottom of the clamping component 7. The inner side of the main gasket 1 is provided with a slot 11 that matches the locking block 10. The locking block 10 and the slot 11 are locked together to increase the stability of the clamping component installation.
[0023] The limiting component includes a connecting frame 12. The inner side of the mounting frame 3 has a connecting groove 13 for the connecting frame 12 to slide left and right. The inner side of the connecting frame 12 has multiple threaded holes 14 that are compatible with the first bolt 4. The connecting frame 12 is provided with a second bolt 5 through it and is threadedly connected to it. The connecting frame 12 slides left and right along the connecting groove 13 of the mounting frame 3, so that the device can be adapted to chucks of different sizes. The second bolt 5 passes through the connecting hole and locks into the threaded hole 14 to fix the position of the connecting frame 12. It is also fixedly connected to the chuck through the first bolt 4 and the second bolt 5, which effectively offsets the off-center load impact of the pipe at a large angle and indirectly ensures the safety and efficiency of manual pipe lowering.
[0024] A protective block 15 is fixedly installed on the inner wall of the connecting frame 12. The front side of the protective block 15 is at the same level as the front side of the mounting frame 3. A connecting hole is opened on the inner side of the connecting frame 12 so that the second bolt 5 can pass through. The connection stability between the connecting frame 12 and the chuck is increased by the action of the protective block 15.
[0025] The above embodiment discloses a special pipe-lowering device for roof gas drilling. During use, the connecting frame 12 slides left and right along the connecting groove 13 of the mounting frame 3, thereby adapting the device to chucks of different sizes. The second bolt 5 passes through the connecting hole and locks into the threaded hole 14 to fix the position of the connecting frame 12. It is fixed to the chuck by the first bolt 4 and the second bolt 5, effectively offsetting the eccentric load impact of pipe lowering at a large angle, indirectly ensuring the safety and efficiency of manual pipe lowering. The mounting block 6 is embedded in the first mounting port 8 of the main gasket 1, and the clamping part 7 corresponds to the second mounting port 9. During use, the conical gasket 2 and the main gasket 1 are inserted into the through hole of the hydraulic chuck of the drilling rig. The device is symmetrically fixed on the front end cover of the drilling rig chuck 17 by the first bolt 4 and the second thread 5. The chuck drives the device to move and clamp the sealing pipe. Then, the drilling rig lowers the sealing pipe into the hole to achieve effective clamping of the φ63mm sealing pipe 16, eliminating the risk of the sealing pipe falling and injuring people. The clamping components are easy to install and disassemble, making it convenient for workers to install and replace.
