[0002] In my country, underground space is gradually being developed and utilized. Urban water supply, sewage, rainwater pipes, etc. are all buried underground, forming a complex underground pipe network. With the increase of service life and uneven settlement of the foundation, the spliced ​​pipes will inevitably be misaligned, causing the internal water resources to seep outward, wasting my country's precious water resources; in addition, the permeability formed by the migration of seepage water in the soil foundation will also scour the soil foundation, weaken the bearing strength of the soil foundation, and cause the bottom of the pipe to be hollow.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Specific examples are given below.

[0029] See also Figure 1-Figure 8The present invention provides a pipeline dislocation repair device, comprising a central fixed block 1: connecting sleeves 4 are fixed at both ends of the central fixed block 1; a connecting block 5 is fixed at one end of the connecting sleeve 4 away from the central fixed block 1; a plurality of fixing rods 2 are fixed on both sides of the lower end of the central fixed block 1; a moving wheel 3 is fixed at the lower end of the fixing rod 2; a hub motor is arranged inside the moving wheel 3; a plurality of telescopic rods 16 are evenly fixed on the outer side of the connecting block 5; a support plate 6 is arranged at the telescopic end of the telescopic rod 16; the telescopic rod 16 is connected to the support plate 6 through a connecting assembly; two support plates 6 on the same side are fixedly connected by a support rod 7; a positioning assembly is arranged between two support plates 6 adjacent to the same end; a transmission shaft 8 is rotatably connected to the inner side of the central fixed block 1; a transmission screw 12 is fixed at both ends of the transmission shaft 8; one end of the transmission screw 12 away from the transmission shaft 8 is rotatably connected to the connecting block 5; a driving assembly is arranged at the inner side of the central fixed block 1 and at a position corresponding to the transmission shaft 8; the transmission screw 12 is connected to the telescopic rod 16 through a transmission assembly. When working, first lower the device into the pipeline through the inspection well, then drive the device to the position between the two pipelines that need to be repaired through the moving wheel 3, and then start the driving assembly to drive the transmission shaft 8 and the transmission screw 12 to rotate. When the transmission screw 12 rotates, the telescopic end of the telescopic rod 16 is driven to retract through the transmission assembly. When the telescopic end of the telescopic rod 16 moves, the support plate 6 is driven to move away from the connecting block 5 through the connecting assembly, and then the multiple support plates 6 at both ends of the central fixed block 1 are simultaneously expanded outward, so that the two misaligned pipelines are repaired to the same axis with the central fixed block 1 as the center. When the support plates 6 are opened, the multiple adjacent support plates 6 at the same end are positioned through the positioning assembly, so as to avoid The support plate 6 is retracted to the center position. After the two pipes are aligned, the transmission screw 12 is driven to rotate in the opposite direction through the driving assembly, so that the telescopic end of the telescopic rod 16 is retracted. When the telescopic rod 16 is retracted, the connection with the support plate 6 is cancelled through the connecting assembly, and then the device can be moved out of the pipeline through the moving wheel 3. At this time, the support plate 6 and the support rod 7 will remain at the connection position of the two pipes to ensure the stability of the pipeline. This step is achieved through the coordinated structural design of the driving assembly, the transmission assembly, the connecting assembly and the positioning assembly, so that the device can be placed inside the pipeline to reset and repair the misaligned pipeline, which effectively improves the work efficiency of pipeline repair and reduces the cost of repair. At the same time, it improves the support for the pipeline after repair and improves the stability of the pipeline.

[0030] Further, such as Figure 2As shown, the driving assembly includes a driving motor 11; the driving motor 11 is fixed on the inner side of the central fixed block 1; a driving gear 10 is fixed on the output end of the driving motor 11; a transmission gear 9 is fixed at the position of the transmission shaft 8 corresponding to the driving gear 10; and the transmission gear 9 is meshed and connected with the driving gear 10. When working, firstly, the driving motor 11 is started, so that the driving motor 11 drives the driving gear 10 to rotate, and when the driving gear 10 rotates, the transmission shaft 8 is driven to rotate through the transmission gear 9 meshed with it, and when the transmission shaft 8 rotates, the transmission screw 12 fixed thereto is driven to rotate at the same time. This step can be achieved through the matching structure design of the driving gear 10, the transmission gear 9 and the transmission shaft 8, so that when the driving motor 11 is started, the transmission shaft 8 can be driven to rotate through the driving gear 10 and the transmission gear 9, thereby driving the transmission screw 12 to rotate.

[0031] Further, such as Figure 2 and Figure 3 As shown, the transmission assembly includes a moving seat 13; the moving seat 13 is arranged on the outside of the transmission screw 12; the moving seat 13 is threadedly connected to the transmission screw 12; a plurality of connecting protrusions 14 are evenly fixed on the outside of the moving seat 13; the connecting protrusions 14 are slidingly connected to the connecting sleeve 4; the end of the connecting protrusion 14 away from the transmission screw 12 is rotatably connected to the connecting rod 15; the end of the connecting rod 15 away from the connecting protrusion 14 is rotatably connected to the fixed base 19; the fixed base 19 is fixedly connected to the telescopic end of the telescopic rod 16. During operation, when the transmission screw 12 rotates, it drives the moving seat 13 threadably connected to it to move along the axial direction of the transmission screw 12. When the moving seat 13 moves, the connecting protrusion 14 fixed thereto drives the connecting rod 15 and the end connected to the connecting protrusion 14 to move simultaneously, thereby driving the other end of the connecting rod 15 to drive the fixed base 19 to move along the axial direction of the telescopic rod 16, thereby driving the telescopic end of the telescopic rod 16 to extend, and then the support plate 6 is unfolded through the connecting assembly. This step is achieved through the matching structural design of the moving seat 13, the connecting protrusion 14 and the connecting rod 15, so that the telescopic end of the telescopic rod 16 can be extended when the transmission screw 12 rotates, thereby moving the support plate 6 away from the connecting block 5 through the connecting assembly, and then the pipeline is repaired by the movement of the support plate 6.

[0032] like Figure 4As shown, the connecting assembly includes a fixed shaft 20; the fixed shaft 20 is fixed at one end of the fixed base 19 away from the telescopic rod 16; a fixed flat-top cone block 22 is fixed to the top of the fixed shaft 20; a sliding flat-top cone block 21 is slidably connected to the outer side of one end of the fixed shaft 20 close to the fixed flat-top cone block 22; a connecting groove 25 is opened at a position of the support plate 6 corresponding to the fixed shaft 20; the fixed flat-top cone block 22 and the sliding flat-top cone block 21 are plug-connected with the connecting base 18 through the connecting groove 25; a disassembly assembly is provided on the inner side of the connecting base 18 and between the fixed flat-top cone block 22 and the sliding flat-top cone block 21. During operation, when the telescopic rod 16 is extended, the fixed shaft 20 will be driven to move through the fixed base 19. When the fixed shaft 20 moves, it will drive the sliding flat-top cone block 21 and the fixed flat-top cone block 22 to move at the same time. When the fixed flat-top cone block 22 moves to the inside of the connecting groove 25 and contacts the support plate 6, the disassembly component cancels the limit on the fixed flat-top cone block 22, so that the fixed flat-top cone block 22 can be moved out from the inside of the connecting base 18 when the telescopic rod 16 is retracted. This step is achieved through the coordinated structural design of the sliding flat-top cone block 21, the fixed flat-top cone block 22 and the disassembly component, so that the fixed shaft 20 can be separated from the connecting base 18 after the support plate 6 is opened, thereby retaining the support plate 6 at the connecting position of the pipeline, continuously supporting the pipeline, and improving the stability of the pipeline.

[0033] like Figure 5As shown, the disassembly assembly includes a plurality of plug-in blocks 23; the plurality of plug-in blocks 23 are evenly arranged on the inner side of the connecting base 18 and at positions corresponding to the fixed flat-top cone block 22 and the sliding flat-top cone block 21; the plug-in blocks 23 are slidably connected to the connecting base 18; the lower end of the plug-in block 23 on the side close to the fixed shaft 20 is set as an inclined surface; a plug-in spring 24 is fixed to one end of the plug-in block 23 away from the fixed shaft 20; and the end of the plug-in spring 24 away from the plug-in block 23 is fixedly connected to the connecting base 18. When working, when the telescopic end of the telescopic rod 16 is extended, it drives the fixed base 19 and the fixed shaft 20 to move at the same time. When the fixed shaft 20 moves, it drives the fixed flat-top cone block 22 to move at the same time. When the fixed flat-top cone block 22 moves to the inside of the connecting groove 25, it squeezes the plug-in block 23, so that the plug-in block 23 moves in the direction away from the fixed flat-top cone block 22. When the fixed flat-top cone block 22 moves to be separated from the plug-in block 23, the plug-in block 23 moves to the position between the fixed flat-top cone block 22 and the sliding flat-top cone block 21 under the elastic action of the plug-in spring 24. When the fixed flat-top cone block 22 continues to move, the sliding flat-top cone block 21 squeezes the plug-in block 23. When the sliding flat-top cone block 21 moves to the position above the plug-in block 23, the plug-in block 23 cancels the limit on the fixed flat-top cone block 22. When the telescopic rod 16 is retracted, The sliding flat-top cone block 21 will squeeze the plug-in block 23, causing the plug-in block 23 to move in the direction close to the plug-in spring 24. When the fixed shaft 20 moves downward, the sliding flat-top cone block 21 will slide along the axial direction of the fixed shaft 20 under the action of the plug-in block 23. When the sliding flat-top cone block 21 moves to fit with the fixed flat-top cone block 22, the fixed flat-top cone block 22 and the sliding flat-top cone block 21 can be moved out from the inside of the connecting groove 25, thereby enabling the support plate 6 to be separated from the telescopic rod 16. This step is achieved through the coordinated structural design of the fixed flat-top cone block 22, the sliding flat-top cone block 21, the plug-in block 23 and the plug-in spring 24, so that the fixed shaft 20 can be separated from the connecting base 18 after the support plate 6 is opened, thereby retaining the support plate 6 at the connection position of the pipeline, continuously supporting the pipeline, and improving the stability of the pipeline.

[0034] like Figure 7As shown, the positioning assembly includes a limiting plate 27; the limiting plate 27 is fixed at the inner position of both ends of the support plate 6; two positioning rods 17 are arranged at the position between two adjacent limiting plates 27; the two positioning rods 17 are evenly connected to the two limiting plates 27 in a sliding manner; a plurality of limiting grooves 26 are evenly opened on the side where the two positioning rods 17 are close to each other; and a plug-in assembly is arranged at the inner side of the positioning rod 17 and at a position corresponding to the limiting groove 26. During operation, when multiple support plates 6 are unfolded, the limiting plate 27 and the positioning rod 17 will slide, and when the limiting plate 27 moves, the positioning rod 17 will be limited by the plug-in assembly, so that the two ends of the positioning rod 17 cannot move in the direction close to the support plate 6. This step is designed by the matching structure of the plug-in assembly, the positioning rod 17 and the limiting plate 27, so that when the support plate 6 is unfolded, the two adjacent support plates 6 can be fixed, thereby preventing the multiple support plates 6 from shrinking to the center position, and improving the stability of the support plate 6.

[0035] like Figure 8 As shown, the plug-in assembly includes a limit block 29; the limit block 29 is arranged on the inner side of the limit plate 27; the limit block 29 is slidably connected with the limit plate 27; the limit block 29 is plugged and connected with the positioning rod 17 through the limit groove 26; the limit spring 30 is fixed to the end of the limit block 29 away from the positioning rod 17; and the end of the limit spring 30 away from the limit block 29 is fixedly connected with the limit plate 27. During operation, when the limit plate 27 moves, the limit block 29 will be driven to move at the same time. When the limit block 29 moves to a position corresponding to the limit groove 26, the limit block 29 is pushed to the inner side of the limit groove 26 under the elastic action of the limit spring 30, thereby completing the limiting of the positioning rod 17. This step enables the positioning rod 17 to be limited by the matching structure design of the limit block 29 and the limit spring 30, thereby improving the stability of the support plate 6 through the positioning rod 17.

[0036] like Figure 7 As shown, anti-slip plates 28 are fixed to both ends of the positioning rod 17; the diameter of the anti-slip plates 28 is larger than the diameter of the positioning rod 17. This step effectively prevents the positioning rod 17 from slipping out from the inner side of the limiting plate 27.

[0037] Working principle: When working, first lower the device into the pipeline through the inspection well, then drive the device to the position between the two pipelines that need to be repaired through the moving wheel 3, and then start the driving motor 11, so that the driving motor 11 drives the driving gear 10 to rotate. When the driving gear 10 rotates, it drives the transmission shaft 8 to rotate through the transmission gear 9 meshing with it. When the transmission shaft 8 rotates, it drives the transmission screw 12 fixed thereto to rotate at the same time; when the transmission screw 12 rotates, it drives the moving seat 13 threadedly connected thereto to move along the axial direction of the transmission screw 12. When the moving seat 13 moves, it drives the connecting rod 15 and the end connected to the connecting protrusion 14 to move simultaneously through the connecting protrusion 14 fixed thereto. Thereby, the other end of the connecting rod 15 drives the fixed base 19 to move along the axial direction of the telescopic rod 16, thereby driving the telescopic end of the telescopic rod 16 to extend, and then the support plate 6 is unfolded through the connecting component; when the telescopic rod 16 extends, it drives the fixed shaft 20 to move through the fixed base 19, and when the fixed shaft 20 moves, it drives the sliding flat-top cone block 21 and the fixed flat-top cone block 22 to move at the same time, and when the fixed flat-top cone block 22 moves to the inside of the connecting groove 25 and contacts with the support plate 6, the disassembly component cancels the limit of the fixed flat-top cone block 22, so that the fixed flat-top cone block 22 can be moved out from the inside of the connecting base 18 when the telescopic rod 16 contracts; when the telescopic end of the telescopic rod 16 extends, it drives the fixed base 19 and the fixed The fixed shaft 20 moves at the same time. When the fixed shaft 20 moves, it drives the fixed flat-top cone block 22 to move at the same time. When the fixed flat-top cone block 22 moves to the inside of the connecting groove 25, it squeezes the plug-in block 23, so that the plug-in block 23 moves in the direction away from the fixed flat-top cone block 22. When the fixed flat-top cone block 22 moves to be separated from the plug-in block 23, the plug-in block 23 moves to the position between the fixed flat-top cone block 22 and the sliding flat-top cone block 21 under the elastic action of the plug-in spring 24. When the fixed flat-top cone block 22 continues to move, the sliding flat-top cone block 21 squeezes the plug-in block 23. When the sliding flat-top cone block 21 moves to a position above the plug-in block 23, the plug-in block 23 cancels the limit on the fixed flat-top cone block 22. When the telescopic rod 16 is retracted When the fixed shaft 20 is retracted, the sliding flat-top cone block 21 will squeeze the plug-in block 23, so that the plug-in block 23 moves in the direction close to the plug-in spring 24. When the fixed shaft 20 moves downward, the sliding flat-top cone block 21 will slide along the axial direction of the fixed shaft 20 under the action of the plug-in block 23. When the sliding flat-top cone block 21 moves to fit with the fixed flat-top cone block 22, the fixed flat-top cone block 22 and the sliding flat-top cone block 21 can be moved out from the inner side of the connecting groove 25, so that the support plate 6 and the telescopic rod 16 can be separated; when multiple support plates 6 are unfolded, the limiting plate 27 and the positioning rod 17 will slide. When the limiting plate 27 moves, the positioning rod 17 will be limited by the plug-in assembly, so that the two ends of the positioning rod 17 cannot move in the direction close to the support plate 6;When the limiting plate 27 moves, the limiting block 29 will be driven to move at the same time. When the limiting block 29 moves to the position corresponding to the limiting groove 26, the limiting block 29 is pushed to the inner side of the limiting groove 26 under the elastic action of the limiting spring 30, thereby completing the limiting of the positioning rod 17.
