[0002] Transport pipelines are very important material transportation channels in the industrialization process. With the development of society, municipal engineering has also made rapid progress, and the number of underground pipe networks for sewage discharge is also increasing continuously. In the case of long-term use of underground pipe networks, local leakage points or cracks may occur, affecting the drainage of the pipeline. With the corrosion and aging of the pipeline, the application of pipeline lining repair technology can greatly solve the leakage problem caused by pipeline corrosion and aging, and at the same time reduce the construction difficulty and cost.

[0003] Existing pipeline lining repair methods include excavation repair methods and trenchless repair methods. Among them, excavation repair has problems such as large project volume, high labor and material consumption. In contrast, trenchless repair has the advantages of small project volume, saving labor and materials, and little impact on the surrounding environment.

[0004] When the existing trenchless pipeline repair method is under construction, a repair lining coated with a curing agent is sleeved on a rubber airbag. Through external air supply, the rubber airbag expands, and the expanded rubber airbag will fit the repair lining with the pipeline to be repaired to repair the pipeline. However, there are still some problems. If the repair lining and the pipeline wall to be repaired are not properly treated after they are fitted, there will be a certain gap, which may cause the curing agent to leak from these gaps, thus affecting the pipeline repair effect.

The drawings described in the present invention are only schematic diagrams.

[0024] A pipeline lining repairer for preventing premature curing provided by the present invention, as Figures 1 to 3As shown in the figure, it includes a horizontally arranged support pipe 1. The support pipe 1 is a hollow pipe. A rubber airbag 2 is fixedly sleeved on the support pipe 1. A repair bushing 3 coated with a curing agent is sleeved outside the rubber airbag 2. A pressing assembly 4 is arranged between the rubber airbag 2 and the support rod, which includes a first support rod 41, a second support rod 42 and a pressure plate 43. A number of first support rods 41 are provided. The number of first support rods 41 is arranged in an array along the axis of the support pipe 1. One end of each of the number of first support rods 41 penetrates through and is fixedly connected to the support pipe 1. A second support rod 42 is slidably arranged in each of the number of first support rods 41. Pressure plates 43 are fixedly arranged at the ends of the second support rods 42. The first support rod 41, the second support rod 42 and the pressure plate 43 are used to extrude the rubber airbag 2 when the rubber airbag 2 expands and fits the repair bushing 3 with the inner wall of the pipeline to be repaired. A control member 5 is arranged in the support pipe 1. The control member 5 is used to control the second support rod 42 to slide out of the first support rod 41. The slid-out second support rod 42 drives the pressure plate 43 to press on the rubber airbag 2.

[0025] After the rubber airbag 2 on the support pipe 1 and the repair bushing 3 are located at the inner wall of the pipeline to be repaired, at this time, the rubber airbag 2 expands to initially make the repair bushing 3 coated with the curing agent fit with the inner wall of the pipeline. At this time, the controller 17 will push the set second support rod 42 to slide in the first support rod 41, so as to make the pressure plate 43 fit with the rubber airbag 2 and press on the rubber airbag 2, further making the repair bushing 3 coated with the curing agent fit with the inner wall of the pipeline and preventing the leakage of the curing agent from affecting the repair effect.

[0026] Preferably, as Figures 1 to 3 shown, the control member 5 includes a cylinder 51, a moving rod 52 and a number of first hinge rods 53. The cylinder 51 is horizontally and fixedly arranged in the support pipe 1. The output end of the cylinder 51 is fixedly connected to the moving rod 52. The number of first hinge rods 53 is arranged corresponding to the number of second support rods 42 one by one. Each of the number of second support rods 42 is hinged to the moving rod 52 through the number of first hinge rods 53. Each of the number of pressure plates 43 is set to be arc-shaped, and the arc of the pressure plate 43 is the same as the radian of the pipeline to be repaired.

[0027] After the rubber airbag 2 expands and squeezes the repair bushing 3 coated with the curing agent to fit with the inner wall of the pipeline, at this time, the cylinder 51 is opened to push the set moving rod 52. The moving moving rod 52 will make the set second support rod 42 slide in the first support rod 41 through the set first hinge rod 53, providing power for the second support rod 42 to squeeze the pressure plate 43 on the rubber airbag 2. In order to make the pressure plate 43 better squeeze the repair bushing 3, the present invention sets the pressure plate 43 to be arc-shaped, so that each part of the repair bushing 3 is evenly stressed and better fits on the inner wall of the pipeline.

[0028] Preferably, Figures 1 to 3 As shown, one end of the support tube 1 is connected to a traction member 6, and the traction member 6 includes a moving tube 61, a support block 62, a second hinge rod 63 and a first roller 64. One end of the moving tube 61 is rotatably connected to the support tube 1, and a plurality of second hinge rods 63 are arranged. A plurality of support blocks 62 are fixedly arranged on the outer peripheral side of the moving tube 61, and the plurality of support blocks 62 are arranged in an array along the axis of the moving tube 61. The side of the support block 62 away from the moving tube 61 is connected to the first roller 64 through the second hinge rod 63. A cleaning ring 7 and a scraping ring 8 are sleeved on the moving tube 61, and the distance between the scraping ring 8 and the support tube 1 is greater than the distance between the cleaning ring 7 and the support tube 1.

[0029] The drive provided in the movable tube 61 is turned on, so that the movable tube 61 moves in the pipeline with the assistance of the second hinged rod 63 and the first roller 64, and the plurality of second hinged rods 63 and the first roller 64 are arranged in an array along the axis of the movable tube 61 to increase the stability of the movable tube 61. The present invention also provides a scraping ring 8 and a cleaning ring on the traction member 6. Since the traction member 6 is placed at the front end of the support tube 1, when the traction member 6 passes through the place in the pipeline that needs to be repaired, the scraping ring 8 is used to scrape away the debris damaged in the pipeline, and the cleaning ring is used to further clean the scraped position to prevent the debris in the place where the pipeline needs to be repaired from affecting the repair sleeve 3 coated with a curing agent when it is attached to the inner wall of the pipeline.

[0030] Preferably, Figures 1 to 4 As shown, a support ring 9 is provided at one end of the support tube 1 away from the moving tube 61, and a plurality of third hinged rods 10 are hingedly connected in an array around the support ring 9, and a second roller 11 is hingedly connected at one end of the plurality of third hinged rods 10 away from the support ring 9, a support frame 12 is fixedly provided inside the support ring 9, and a motor 13 is fixedly provided on the support frame 12, and one end of the motor 13 is fixedly connected to the support tube 1, and the axis of the motor 13 coincides with the axis of the support tube 1.

[0031] When the traction member 6 is pulling, the support tube 1 and the support ring 9 move in the pipeline. The support ring 9 moves in the pipeline with the assistance of the third hinge rod and the second roller 11, and a motor 13 is arranged in the support ring 9 through the support frame 12. The motor 13 drives the entire support tube 1 to rotate, so that the several pressure plates rotate together to form a closed loop to squeeze the repair bushing 3 at various places, so as to better fit the repair bushing 3 to the inner wall of the pipeline.

[0032] Preferably, Figures 1 to 4As shown in the figure, a camera 14 is provided on one side of the support pipe 1 close to the moving pipe 61. An air charging pipe 15 is provided on one side of the rubber airbag 2. The air inlet end of the air charging pipe 15 is connected to an air pump 16. The air pump 16 is limited on the support pipe 1. A controller 17 is provided on the support ring 9. The controller 17 is electrically connected to the camera 14, the controller 17 is electrically connected to the air pump 16, the controller 17 is connected to the motor 13, and the controller 17 is electrically connected to the air cylinder 51.

[0033] In the present invention, the position of the inner wall of the pipe to be repaired is determined by the camera 14, and the information is fed back to the controller 17. The controller 17 controls the air pump 16 to work, and the gas is introduced into the rubber airbag 2 through the air charging pipe 15 to expand the rubber airbag 2, and controls the air cylinder 51 to extend and the motor 13 to rotate.

[0034] Preferably, as Figures 1 to 3 shown, a moving unit is built in the moving pipe 61 and is controlled by an external controller 17. A rotating pipe 18 is rotatably connected to one side of the moving pipe 61 close to the support pipe 1. A magnetic adsorption plate 19 is provided at the end of the rotating pipe 18. An electromagnet 20 is provided on one side of the support pipe 1 close to the rotating pipe 18. A traction rope 21 is fixedly connected to one end of the support ring 9 away from the moving pipe 61.

[0035] In the present invention, the support pipe 1 and the moving pipe 61 are connected by the electromagnet 20 and the magnetic adsorption plate 19 and are assisted by the rotating pipe 18. The rotating pipe 18 ensures that the support pipe 1 can rotate normally. When the repair work is completed, the electromagnet 20 and the magnetic adsorption plate 19 are separated, and part of the traction member 6 is removed from one end of the pipe, and the remaining part is pulled out by the staff through the traction rope 21.

[0036] The usage method of the pipeline inner lining repairer for preventing premature curing of the present invention is as follows:

[0037] Place the moving pipe 61 in the pipeline. Through external control, the moving pipe 61 moves in the pipeline with the assistance of the first roller 64. When the camera 14 determines the position of the inner wall of the pipeline to be repaired, the information will be transmitted to the controller 17. At this time, the controller 17 will control the air pump 16 to work, and the gas will be introduced into the rubber airbag 2 through the air charging pipe 15 to expand the rubber airbag 2, so that the repair bushing 3 coated with the curing agent fits the inner wall of the pipeline.

[0038] At the same time, the cylinder 51 and the motor 13 are driven, and the cylinder 51 pushes the movable rod 52. The moving movable rod 52 causes the second support rod 42 to slide inside the first support rod 41 through the first hinged rod 53, providing power for the second support rod 42 so that it squeezes the pressure plate 43 onto the rubber airbag 2. The motor 13 drives the entire support tube 1 to rotate, so that the several pressure plates rotate together to form a closed loop to squeeze the repair bushing 3 at various locations, so as to better fit the repair bushing 3 to the inner wall of the pipe.

[0039] When the repair work is completed, the electromagnet 20 is separated from the magnetic adsorption plate 19, and part of the traction member 6 is moved out from one end of the pipeline, while the remaining part is pulled out by the staff through the traction rope 21.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
