Description

Technical Field

[0001] This utility model relates to the field of mine backfilling engineering technology, and in particular to a slurry conveying pipe connection assembly for mine backfilling. Background Technology

[0002] In modern mining, paste or high-concentration slurry backfilling technology is widely used to prevent goaf collapse, improve resource recovery rates, and ensure operational safety. This technology efficiently transports backfill material from the surface to the underground goaf through a long-distance, high-pressure pipeline system. Currently, most pipelines use flange connections to ensure the system's sealing and structural stability, adapting to complex working conditions of high pressure and high abrasion.

[0003] However, traditional flange connections are cumbersome to assemble and disassemble, resulting in long processing times and hindering rapid maintenance and replacement. Therefore, improvements are urgently needed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a connection component for a slurry conveying pipe for mine filling, which aims to solve the technical problems of the above-mentioned flange connection being cumbersome to disassemble and assemble, time-consuming, and not conducive to rapid maintenance and replacement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A slurry conveying pipe connection assembly for mine backfilling includes a first conveying pipe, a second conveying pipe, and a connecting conveying pipe, and further includes: Two fixed annular sleeves are provided, one fixed annular sleeve is fixedly installed on the first conveying pipe, and the other fixed annular sleeve is fixedly installed on the second conveying pipe; Two first sealing rings are provided, and the two first sealing rings are sleeved on the fixed annular sleeve and slidably connected to the fixed annular sleeve. Two second sealing rings are provided, and the two second sealing rings are sleeved on the connecting conveying pipe and slidably connected to the connecting conveying pipe. A fixing ring is disposed on the connecting conveying pipe and is fixedly connected to the connecting conveying pipe; Two elastic mechanisms are provided, symmetrically arranged on the fixed ring, for compressing the first sealing ring and the second sealing ring to prevent slurry leakage; A fixing plate is fixedly mounted on the fixing ring; A rotating mechanism, mounted on the fixed plate, is used to compress and stretch the elastic mechanism.

[0006] Preferably, the elastic mechanism includes: Multiple springs are provided, and the multiple springs are disposed on the fixed ring, with one end of each spring being fixedly connected to the fixed ring. Two annular sealing plates are provided. The two annular sealing plates are slidably disposed on the connecting conveying pipe, fixedly connected to the other end of the spring, and slidably connected to the fixed ring. Two movable rings are provided, which are fixedly connected to the annular sealing plate and slidably connected to the connecting conveying pipe.

[0007] Preferably, two isolation grooves are symmetrically formed on the fixing ring to limit the movement trajectory of the annular sealing plate and to isolate the spring.

[0008] Preferably, the rotating mechanism includes: A bidirectional screw is rotatably mounted on the fixed plate; A manual rotating frame is mounted on the bidirectional screw and fixedly connected to one end of the bidirectional screw. Two sliding mechanisms are provided, and the two sliding mechanisms are symmetrically arranged on the bidirectional screw.

[0009] Preferably, the sliding mechanism includes: Two threaded sleeves are provided, symmetrically arranged on the bidirectional screw and threadedly connected to the bidirectional screw. Two connecting plates are provided. The two connecting plates are fixedly mounted on the threaded sleeve, slidably connected to the fixed plate, and fixedly connected to the annular sealing plate.

[0011] Preferably, two annular sliding grooves are symmetrically formed on the connecting conveying pipe to define the sliding trajectory of the second sealing ring and the moving ring.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: By coordinating the fixed annular sleeve, fixed ring, elastic mechanism, fixed plate, and rotating mechanism, rotating the rotating mechanism drives the two elastic mechanisms away from each other. The elastic mechanisms compress the first and second sealing rings and fit them onto the conveying pipe, filling the gap between the first conveying pipe, the second conveying pipe, and the connecting conveying pipe, thus achieving a quick connection between the conveying pipes. By rotating the rotating mechanism, the two elastic mechanisms can be brought closer together, allowing for quick disassembly, reducing maintenance time, and enabling rapid replacement.

[0025] A slurry conveying pipe connection assembly for mine backfilling includes a first conveying pipe 1, a second conveying pipe 2, and a connecting conveying pipe 3, and further includes: Reference Figures 1 to 5 In a preferred embodiment, there are two fixed annular sleeves 4, one fixed annular sleeve 4 is fixedly disposed on the first conveying pipe 1, and the other fixed annular sleeve 4 is fixedly disposed on the second conveying pipe 2. Two first sealing rings 5 ​​are provided, and the two first sealing rings 5 ​​are sleeved on the fixed annular sleeve 4 and slidably connected to the fixed annular sleeve 4. Two second sealing rings 6 are provided, and the two second sealing rings 6 are sleeved on the connecting conveying pipe 3 and slidably connected with the connecting conveying pipe 3. A fixing ring 7 is disposed on the connecting conveying pipe 3 and is fixedly connected to the connecting conveying pipe 3; it is used to isolate and protect the spring 9 and limit the movement trajectory of the annular sealing plate 10. Two elastic mechanisms are provided, symmetrically arranged on the fixed ring 7, for compressing the first sealing ring 5 and the second sealing ring 6 to prevent slurry leakage; the elastic mechanisms include: Multiple springs 9 are provided, and multiple springs 9 are disposed on the fixed ring 7, with one end of each spring 9 being fixedly connected to the fixed ring 7. Two annular sealing plates 10 are provided. The two annular sealing plates 10 are slidably disposed on the connecting conveying pipe 3, fixedly connected to the other end of the spring 9, and slidably connected to the fixed ring 7. Two movable rings 11 are provided. The two movable rings 11 are set on the annular sealing plate 10, fixedly connected to the annular sealing plate 10, and slidably connected to the connecting conveying pipe 3.

[0026] Two isolation grooves 12 are symmetrically provided on the fixed ring 7 to limit the movement trajectory of the annular sealing plate 10, and an isolation spring 9.

[0027] Two annular sliding grooves 18 are symmetrically formed on the connecting conveying pipe 3 to limit the sliding trajectory of the second sealing ring 6 and the moving ring 11.

[0028] During operation, the rotating mechanism drives the two annular sealing plates 10 to move away from each other and fit onto the fixed annular sleeve 4. The annular sealing plates 10 drive the moving ring 11 to move along the annular sliding groove 18. The annular sealing plates 10 compress the first sealing ring 5 on the fixed annular sleeve 4, and the moving ring 11 compresses the second sealing ring 6, thereby achieving the connection and effective sealing of the conveying pipeline. The spring 9 releases elastic potential energy to generate pressure on the annular sealing plates 10, thereby effectively preventing the bidirectional screw 13 from rotating. When the annular sealing plates 10 move closer to each other and expose the annular sliding groove 18, it is convenient to replace the first sealing ring 5 and the second sealing ring 6.

[0029] A fixing plate 8 is fixedly mounted on a fixing ring 7; it is used to define the position of the rotating mechanism. Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 In a preferred embodiment, a rotating mechanism is disposed on the fixed plate 8 and is used to compress and stretch the elastic mechanism. The rotating mechanism includes: The bidirectional screw 13 is rotatably mounted on the fixed plate 8; The manual rotating bracket 14 is mounted on the bidirectional screw 13 and is fixedly connected to one end of the bidirectional screw 13. Two sliding mechanisms are provided, symmetrically arranged on the bidirectional screw 13. The sliding mechanisms include: Two threaded sleeves 15 are provided, and the two threaded sleeves 15 are symmetrically arranged on the bidirectional screw 13 and threadedly connected to the bidirectional screw 13. There are two connecting plates 16. The two connecting plates 16 are fixedly mounted on the threaded sleeve 15, slidably connected to the fixed plate 8, and fixedly connected to the annular sealing plate 10.

[0030] Two limiting grooves 17 are symmetrically provided on the fixed plate 8 to limit the sliding trajectory of the connecting plate 16.

[0031] During operation, the manual rotating frame 14 is manually rotated, which drives the bidirectional screw 13 to rotate. The bidirectional screw 13 drives the two threaded sleeves 15 to move closer or further apart. The threaded sleeves 15 drive the two connecting plates 16 to move. The connecting plates 16 drive the two annular sealing plates 10 to move and fit onto the fixed annular sleeve 4, realizing the quick connection of the pipeline. The connecting plates 16 drive the annular sealing plates 10 to move closer to each other to disconnect, making disassembly simple, reducing maintenance time, and enabling quick replacement.

[0032] Working principle: By manually rotating the manual rotating frame 14, the manual rotating frame 14 drives the bidirectional screw 13 to rotate. The bidirectional screw 13 drives the two threaded sleeves 15 to move closer together. The threaded sleeves 15 drive the two connecting plates 16 to move. The connecting plates 16 drive the annular sealing plates 10 to move closer together and expose the annular sliding groove 18, which facilitates the replacement of the first sealing ring 5 and the second sealing ring 6. By rotating the manual rotating frame 14 in the opposite direction, the connecting plates 16 are moved, thereby driving the two annular sealing plates 10 to move away from each other until they are moved and fitted onto the fixed annular sleeve 4. The annular sealing plates 10 drive the moving ring 11 to move along the annular sliding groove 18. The annular sealing plates 10 compress the first sealing ring 5 on the fixed annular sleeve 4, and the moving ring 11 compresses the second sealing ring 6, thereby realizing the connection and effective sealing of the conveying pipeline. The spring 9 releases elastic potential energy to generate pressure on the annular sealing plate 10, thereby effectively preventing the bidirectional screw 13 from rotating and realizing the rapid connection of the pipeline.
