Description
Technical Field
[0001] This application relates to the technical field of municipal engineering underground pipeline repair, and specifically relates to a municipal underground pipeline repair device. Background Art
[0002] Municipal underground pipelines are an important part of urban infrastructure. Over time, these pipelines will be damaged for various reasons and need to be repaired in a timely manner. Traditional repair methods usually involve excavating and replacing entire sections of pipelines. This method is not only costly but also has a greater impact on urban traffic and residents' lives.
[0003] Currently, the repair of municipal underground pipelines usually adopts the methods of excavation and replacement or local repair. Although excavation and replacement can fundamentally solve the problem, it is costly and affects urban traffic. Local repair mostly uses materials such as quick-drying cement for filling, but this method has poor durability and is prone to damage again. Summary of the Utility Model
[0004] In view of the deficiencies of the prior art, this application provides a municipal underground pipeline repair device, which has the advantages of reducing the impact on urban traffic, etc., and solves the problems that currently, the repair of municipal underground pipelines usually adopts the methods of excavation and replacement or local repair. Although excavation and replacement can fundamentally solve the problem, it is costly and affects urban traffic. Local repair mostly uses materials such as quick-drying cement for filling, but this method has poor durability and is prone to damage again.
[0005] To achieve the above object, this application provides the following technical solution: A municipal underground pipeline repair device includes a first fixed column and a second fixed column. One side of the first fixed column is fixedly connected to a motor box. Inside the motor box, a motor is fixedly connected. The output end of the motor passes through the motor box and is fixedly connected to a rotating block. Three electric push rods arranged in a circular array are fixedly connected to the outer wall of the rotating block. The telescopic ends of the three electric push rods are all fixedly connected to cleaning brushes. Four support columns arranged in a circular array are fixedly connected to one side of the rotating block. A detection module is fixedly connected to one side of the four support columns. One side of the second fixed column is fixedly connected to a first mounting plate.
[0006] Through the above solution, the rotating block is driven by the motor, enabling the three electric push rods and the cleaning brushes thereon to clean the inner wall of the pipeline in all directions and at multiple angles. This design ensures the comprehensiveness and efficiency of the cleaning work, laying a good foundation for the subsequent repair work. The setting of the detection module enables the device to accurately detect the inside of the pipeline before repair, identifying key information such as the damaged position and crack size, which provides an important basis for formulating a targeted repair plan, improving the accuracy and efficiency of the repair work. The design of the first mounting plate enables the second fixing column and its related components to be conveniently connected or separated from other components or equipment, which helps to quickly deploy and evacuate the device during the repair process, improving the work efficiency.
[0007] Furthermore, one side of the first fixing column away from the motor box is fixedly connected with an airbag module, and one side of the airbag module away from the first fixing column is fixedly connected with a second mounting plate.
[0008] Through the above solution, the airbag module can be inflated and expanded to closely fit the inner wall of the pipeline. The airbag module has a certain elasticity and adjustability, so it can adapt to pipelines of different diameters. By adjusting the inflation volume of the airbag, it can closely fit the inner wall of pipelines of various sizes, increasing the applicable range of the device.
[0009] Furthermore, a self-locking steel ring is slidably connected to the outer wall of the airbag module, and two mirror-image distributed sealing strips are fixedly connected to the outside of the self-locking steel ring.
[0010] Through the above solution, as the airbag expands, the self-locking steel ring is tightly pressed against the inner wall of the pipeline. Due to the self-locking steel ring having a strong structure and a certain elasticity, it can closely fit the contour of the inner wall of the pipeline, forming a sealing barrier. The two mirror-image distributed sealing strips fixed to the outside of the self-locking steel ring further enhance the sealing effect. These sealing strips are usually made of soft and wear-resistant materials and can closely fit the tiny gaps and irregular surfaces of the inner wall of the pipeline. When the self-locking steel ring is pushed towards the inner wall of the pipeline by the expansion force of the airbag, the sealing strips will deform accordingly and fill these gaps, thus ensuring the tightness of the seal.
[0011] Furthermore, four fixing rods arranged in a circular array are fixedly connected to the outer walls of the first fixing column and the second fixing column, and sliding grooves are formed inside multiple fixing rods, and extension rods are slidably connected inside multiple sliding grooves.
[0012] Through the above solution, by means of the extension rods slidably connected inside the sliding grooves, the size of the device can be adjusted according to the actual diameter of the pipeline, enabling the device to be applicable to pipelines of various specifications.
[0013] Furthermore, mounting holes are formed inside multiple ones of the fixing rods, three positioning holes are formed inside multiple ones of the extension rods, fixing bolts are fixedly connected inside multiple ones of the mounting holes, and multiple ones of the fixing bolts are slidably arranged inside the positioning holes.
[0014] Through the above solution, the fixing bolts are fixed inside the fixing rods through the mounting holes and are slidably arranged in the positioning holes of the extension rods. After the extension rods are adjusted to appropriate positions, the fixing bolts can be fastened at certain positions in the positioning holes, thereby locking the positions of the extension rods and preventing them from sliding or shifting during the working process. This design ensures the stability and reliability of the device after adjustment.
[0015] Furthermore, shock absorbers are fixedly connected to one sides of multiple ones of the extension rods away from the fixing rods.
[0016] Through the above solution, during the pipeline repair process, especially when operating on old or severely damaged pipelines, various vibration sources may be encountered, such as water flow impact, machine operation, etc. The shock absorbers can effectively absorb and disperse these vibration energies and reduce their impacts on the device and the pipeline itself. The setting of the shock absorbers enables it to adapt to different working environments and conditions.
[0017] Furthermore, driving wheels are fixedly connected to one ends of multiple ones of the shock absorbers away from the extension rods.
[0018] Through the above solution, the addition of the driving wheels enables the entire device to move autonomously inside the pipeline without external traction or pushing, thereby improving the efficiency of the repair operation.
[0019] Furthermore, one side of the first mounting plate is threadedly connected to the second mounting plate.
[0020] Through the above solution, through the threaded connection between the first mounting plate and the second mounting plate, it is convenient to connect the second fixing column to the airbag module.
[0021] Compared with the prior art, the technical solution of the present application has the following beneficial effects:
[0022] This municipal underground pipeline repair device drives the rotating block through a motor, enabling the three electric push rods and the cleaning brushes thereon to clean the inner wall of the pipeline in all directions and at multiple angles. This design ensures the comprehensiveness and high efficiency of the cleaning work, laying a good foundation for the subsequent repair work. The setting of the detection module enables the device to accurately detect the inside of the pipeline before repair, identify key information such as the damaged position and crack size, which provides an important basis for formulating a targeted repair plan and improves the accuracy and efficiency of the repair work. The design of the first mounting plate enables the second fixing column and its related components to be conveniently connected or separated from other components or equipment, which helps to quickly deploy and evacuate the device during the repair process and improves work efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0030] Please refer to Figure 1 、 Figure 2 and Figure 3, A municipal underground pipeline repair device in this embodiment includes a first fixed column 1 and a second fixed column 2. A motor box 3 is fixedly connected to one side of the first fixed column 1. A motor 4 is fixedly connected inside the motor box 3. The output end of the motor 4 passes through the motor box 3 and is fixedly connected to a rotating block 5. Three electric push rods 6 arranged in an annular array are fixedly connected to the outer wall of the rotating block 5. The telescopic ends of the three electric push rods 6 are all fixedly connected to cleaning brushes 7. Four support columns 8 arranged in an annular array are fixedly connected to one side of the rotating block 5. A detection module 9 is fixedly connected to one side of the four support columns 8. The second fixed column 2 is fixedly connected to a first mounting plate 10 on one side. By driving the rotating block 5 with the motor 4, the three electric push rods 6 and the cleaning brushes 7 thereon can clean the inner wall of the pipeline in all directions and at multiple angles. This design ensures the comprehensiveness and efficiency of the cleaning work, laying a good foundation for the subsequent repair work.
[0031] Please refer to Figure 1 , On the side of the first fixed column 1 away from the motor box 3, an airbag module 11 is fixedly connected. On the side of the airbag module 11 away from the first fixed column 1, a second mounting plate 12 is fixedly connected. The airbag module 11 can be inflated and expanded to closely fit the inner wall of the pipeline. The airbag module 11 has a certain elasticity and adjustability, so it can adapt to pipelines of different diameters. By adjusting the inflation amount of the airbag, it can closely fit the inner wall of various sizes of pipelines, increasing the application range of the device. A self-locking steel ring 13 is slidably connected to the outer wall of the airbag module 11. Two sealing strips 14 distributed in a mirror image are fixedly connected to the outside of the self-locking steel ring 13. As the airbag expands, the self-locking steel ring 13 is tightly pressed against the inner wall of the pipeline. Due to the firm structure and certain elasticity of the self-locking steel ring 13, it can closely fit the contour of the inner wall of the pipeline, forming a sealing barrier. The two sealing strips 14 distributed in a mirror image fixed to the outside of the self-locking steel ring 13 further enhance the sealing effect. These sealing strips 14 are usually made of soft and wear-resistant materials and can closely fit the tiny gaps and irregular surfaces of the inner wall of the pipeline. When the self-locking steel ring 13 is pushed against the inner wall of the pipeline by the expansion force of the airbag, the sealing strips 14 will deform accordingly and fill these gaps, thus ensuring the tightness of the seal.
[0032] Please refer to Figure 1 , Figure 3 and Figure 4, on the outer walls of the first fixing post 1 and the second fixing post 2, four fixing rods 15 arranged in an annular array are fixedly connected. Inside each of the multiple fixing rods 15, a sliding groove 16 is formed. Inside each of the multiple sliding grooves 16, an extension rod 17 is slidably connected. By means of the extension rod 17 slidably connected inside the sliding groove 16, the size of the device can be adjusted according to the actual diameter of the pipeline, enabling the device to be applicable to pipelines of various specifications. Inside each of the multiple fixing rods 15, a mounting hole 18 is formed. Inside each of the multiple extension rods 17, three positioning holes 19 are formed. Inside each of the multiple mounting holes 18, a fixing bolt 20 is fixedly connected. Each of the multiple fixing bolts 20 is slidably arranged inside the positioning hole 19. The fixing bolt 20 is fixed inside the fixing rod 15 through the mounting hole 18 and is slidably arranged in the positioning hole 19 of the extension rod 17. When the extension rod 17 is adjusted to a proper position, the fixing bolt 20 can be fastened at a certain position in the positioning hole 19, thereby locking the position of the extension rod 17 and preventing it from sliding or shifting during the working process. This design ensures the stability and reliability of the device after adjustment. On the side of each of the multiple extension rods 17 away from the fixing rod 15, a shock absorber 21 is fixedly connected. During the pipeline repair process, especially when operating on old or severely damaged pipelines, various vibration sources may be encountered, such as water flow impact, machine operation, etc. The shock absorber 21 can effectively absorb and disperse these vibration energies, reducing their impact on the device and the pipeline itself. The setting of the shock absorber 21 enables it to adapt to different working environments and conditions. At one end of each of the multiple shock absorbers 21 away from the extension rod 17, a driving wheel 22 is fixedly connected. The addition of the driving wheel 22 enables the entire device to move autonomously inside the pipeline without external traction or pushing, thereby improving the efficiency of the repair operation. One side of the first mounting plate 10 is threadedly connected to the second mounting plate 12. Through the threaded connection between the first mounting plate 10 and the second mounting plate 12, it is convenient to connect the second fixing post 2 to the airbag module 11.
[0033] In this embodiment, for this municipal underground pipeline repair device, by driving the rotating block 5 with the motor 4, the three electric push rods 6 and the cleaning brushes 7 thereon can clean the inner wall of the pipeline comprehensively and multi-angularly. This design ensures the comprehensiveness and high efficiency of the cleaning work, laying a good foundation for the subsequent repair work. The setting of the detection module 9 enables the device to accurately detect the inside of the pipeline before repair, identifying key information such as the damaged position and the size of the crack, which provides an important basis for formulating a targeted repair plan and improves the accuracy and efficiency of the repair work. The design of the first mounting plate 10 enables the second fixing post 2 and its related components to be conveniently connected or separated from other components or equipment, which helps to quickly deploy and withdraw the device during the repair process and improves the work efficiency.
[0034] It should be noted that the detection module 9 uses lidar for scanning to precisely detect the interior of the pipeline before repair, identify the damaged positions and crack sizes, and provide important basis for the repair work.
[0035] The working principle of the above embodiment is as follows:
[0036] First, according to the diameter of the pipeline to be repaired, adjust the size of the device. Move the sliding extension rod 17 within the chute 16 of the fixed rod 15 until the appropriate length is reached, and then use the fixing bolt 20 to lock the extension rod 17 in a fixed position. Slip the self-locking steel ring 13 onto the outer wall of the airbag module 11. Subsequently, thread-connect the first mounting plate 10 and the second mounting plate 12, and connect and fix the second fixing column 2 to the airbag module 11. Place the entire device into the municipal underground pipeline to be repaired, start the detection module 9 to perform scanning using lidar, and precisely detect the interior of the pipeline. The lidar scans the inner wall of the pipeline to identify key information such as damaged positions and crack sizes, and transmits this data to the operator or the control system. After confirming the damaged position and condition, start the motor 4. The motor 4 drives the rotating block 5 to rotate, thereby driving the three electric push rods 6 and the cleaning brushes 7 thereon to clean the inner wall of the pipeline in all directions and at multiple angles. This step ensures the cleanliness of the inner wall of the pipeline and lays a foundation for the subsequent repair work. Subsequently, by starting the airbag module 11, the airbag expands and tightly adheres to the inner wall of the pipeline. As the airbag expands, the self-locking steel ring 13 is pushed towards the inner wall of the pipeline, and the gap is filled through the sealing strip 14 to achieve the stable fixation and sealing of the device.
