Description

Technical Field

[0001] This utility model belongs to the field of pipeline repair technology, and in particular relates to a trenchless partial repair device for sewage pipelines. Background Technology

[0002] Sewage pipes are an important part of urban infrastructure, responsible for collecting and transporting domestic sewage, industrial wastewater and rainwater. However, after long-term use, the inner wall of the pipes will be damaged due to corrosion, at which point the pipes need to be repaired.

[0003] In trenchless partial repair of sewage pipelines, epoxy resin is an efficient and quick method. Epoxy resin is a high-strength, corrosion-resistant polymer material that, when applied or sprayed onto the damaged area of ​​the pipeline, forms a robust protective layer after curing, restoring the structural integrity and sealing of the pipeline. However, this method is less effective when dealing with smaller diameter pipelines where workers or machinery cannot access the interior. In such cases, the ground must be dug up and the damaged pipe replaced, which is labor-intensive, resource-intensive, and damages the ground, affecting the city's appearance. Utility Model Content

[0004] The purpose of this invention is to provide a trenchless partial repair device for sewage pipes. By incorporating a movable component, specifically by extending an electric push rod, the outer wall of a conical block pushes three support columns away from each other, allowing the rollers to make close contact with the inner wall of the pipe. At this point, a mobile vehicle is driven to the damaged location, where resin is used for repair. After repair, the repair vehicle is driven back to the starting point. Subsequently, two electric push rods are retracted, and after the bottom of the support columns loses support, the springs use elasticity to move the three support columns closer together, facilitating storage and transportation. This method can flexibly adjust the distance between the support columns according to different diameter sewage pipes to adapt to different pipe types. It solves the problem that existing repair methods, when dealing with smaller diameter pipes, make it difficult for workers or repair machines to enter the pipe interior, leading to difficult repairs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a non-excavation partial repair device for sewage pipelines, including a repair vehicle. The repair vehicle includes two vehicle bodies, namely, vehicle body one and vehicle body two. A moving component is installed inside vehicle body one, which includes a conical block and three support columns. A repair component is installed inside vehicle body two, which includes an arc-shaped plate.

[0007] An electric push rod is fixedly connected to the inner wall of each of the two vehicle bodies on opposite sides. The output end of the electric push rod is fixedly connected to the inner wall of the conical block. An annular block is fixedly connected to the outer surface of the support column. Two limiting posts are fixedly connected to the bottom of the annular block. The limiting posts slide through the vehicle body and extend into the interior. Limiting blocks are fixedly connected to the left and right sides of the bottom of the annular block. The limiting blocks slide through the vehicle body and extend into the interior. A roller is rotatably connected to the side of the support column away from the vehicle body via a pin. When the conical block moves, it can simultaneously push the three support columns away from each other, so that the rollers simultaneously contact the inner wall of the pipe. This allows the repair vehicle to adapt to pipes of different diameters, expanding the applicable scenarios of the repair vehicle.

[0008] Furthermore, a spring is fitted on the outer surface of the limiting post, the top of the spring is fixedly connected to the bottom of the annular block, the bottom of the spring is fixedly connected to an outer surface of the vehicle body, the outer side of the conical block is set with a conical surface, and the outer conical surface of the conical block contacts the hemispherical surface on the support post; the conical surface setting on the outer side of the conical block and the hemispherical setting on the support post together make the support posts more smooth and stable when they expand with each other.

[0009] Furthermore, a circular block is fixedly connected to each of the two vehicle bodies on their adjacent sides, and the inner wall of the vehicle body is rotatably connected to the outer surface of the circular block. A connecting column is fixedly connected to each of the two circular blocks on their adjacent sides. The two circular blocks are rotatably connected to the inner wall of the vehicle body, allowing the vehicle body and its internal components to rotate together, which facilitates subsequent repair work. At the same time, the two vehicle bodies are fixedly connected to each other through the connecting column.

[0010] Furthermore, several gear teeth are fixedly connected to the inner wall of the vehicle body two. The circular block on the left side is fixedly connected to a motor one by bolts. The output end of the motor one on the right side is fixedly connected to a gear one by bolts. The gear one is meshed with the vehicle body two through the gear teeth. When the motor one drives the gear one to rotate, the several gear teeth fixed to the inner wall of the vehicle body two can simultaneously drive the entire vehicle body two to rotate together, so that repair work can be carried out on damaged positions in different directions.

[0011] Furthermore, a lifting column is fixedly connected to the bottom of the arc-shaped plate, a rack is fixedly connected to the front of the lifting column, a motor is fixedly connected to the top of the inner wall of the second vehicle body, a gear is fixedly connected to the left output end of the motor by bolts, the back of the gear is meshed with the rack, the lifting column slides through the second vehicle body and extends into the interior, a limit tube is slidably connected to the outer surface of the lifting column, and the top of the limit tube is fixedly connected to the top of the inner wall of the second vehicle body; when the motor drives the gear to rotate, the lifting column is driven to rise and fall through the rack on the front of the lifting column, which can repair pipes of different diameters, greatly improving the repair capability, while the limit tube makes the lifting column rise and fall more smoothly and stably.

[0012] Furthermore, the top of the arc-shaped plate has a circular hole, and a discharge pipe is fixedly connected to the inner wall of the circular hole. The discharge pipe passes through the second vehicle body and extends into the interior. A storage tank is fixedly connected to the bottom of the discharge pipe. A water pump is fixedly connected to the front of the storage tank. Several curing lamps are fixedly connected to both the front and back of the arc-shaped plate. The storage tank is fixed to the inner wall of the second vehicle body. The discharge pipe is a flexible hose, so that the discharge pipe can be raised and lowered together when the arc-shaped plate is raised and lowered. The curing lamps can make the resin solidify quickly.

[0013] Furthermore, a camera is bolted to the top of the vehicle body on the left, and an electric push rod is bolted to the bottom of the vehicle body on the left. A moving vehicle is bolted to the bottom output end of the electric push rod. A high-pressure tank is bolted to the right side of the vehicle body on the right, and several nozzles are bolted to the outer surface of the high-pressure tank. The camera can observe the damaged location within the sealed pipeline for precise repair. At the same time, the moving vehicle provides power to the repair vehicle, moving it within the pipeline. Water stored in the high-pressure tank can clean the damaged location through the nozzles, allowing the resin to better repair the damaged area.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model incorporates a movable component. Specifically, by activating an electric push rod to extend, the outer wall of the conical block pushes the three support columns away from each other, causing the rollers to make close contact with the inner wall of the pipe. At this point, a mobile vehicle is activated, driving the repair vehicle into the sewage pipe. Through camera observation, once the damaged location is reached, resin is used for repair. After the repair is completed, the repair vehicle is driven back to the starting point. Subsequently, two electric push rods are activated to retract. After the bottom of the support columns loses support, the springs use elasticity to move the three support columns closer to each other, facilitating subsequent storage and transportation. This method can flexibly adjust the distance of mutual expansion of the support columns according to sewage pipes of different diameters to adapt to different pipe types.

[0016] 2. This utility model, through the setting of a repair component, specifically involves starting motor one to drive gear one to rotate, and gear one driving the vehicle body two to rotate together through gear teeth. When the arc plate rotates to the damaged position, motor one is turned off, and motor two is started to drive gear two to rotate clockwise. Gear two drives the lifting column to move upward. When the arc plate contacts the damaged position, motor two is turned off, and resin in the storage tank is extracted by a water pump and sprayed onto the damaged position through the discharge pipe. At this time, the curing lamp is turned on to irradiate the resin. After the resin solidifies, motor two is started to retract the arc plate to the outer surface of the vehicle body two. This method can repair any position inside the pipeline, and its good flexibility can improve the repair efficiency.

The output end of the electric push rod 21 is fixedly connected to the inner wall of the conical block 22. An annular block 25 is fixedly connected to the outer surface of the support column 24. Two limiting posts 27 are fixedly connected to the bottom of the annular block 25. The limiting posts 27 slide through the car body 11 and extend into the interior. Limiting blocks 26 are fixedly connected to the left and right sides of the bottom of the annular block 25. The limiting blocks 26 slide through the car body 11 and extend into the interior. A roller 23 is rotatably connected to the side of the support column 24 away from the car body 11 via a pin. When the electric push rod 21 is activated, it extends, and the conical block 22... The outer wall pushes the three support columns 24 away from each other, so that the roller 23 is in close contact with the inner wall of the pipe. At this time, the mobile vehicle 292 is started to drive the repair vehicle 1 into the sewage pipe. After the camera 111 observes and reaches the damaged position, resin is used for repair. After the repair is completed, the repair vehicle 1 is driven back to the starting point. Then, the two electric push rods 21 are activated to retract. After the bottom of the support column 24 loses support, the spring 28 uses elasticity to make the three support columns 24 move closer to each other, which is convenient for subsequent storage and transportation. This method can flexibly adjust the distance of mutual expansion of the support columns 24 according to sewage pipes of different diameters to adapt to different pipes.

[0029] A spring 28 is fitted on the outer surface of the limiting post 27. The top of the spring 28 is fixedly connected to the bottom of the annular block 25, and the bottom of the spring 28 is fixedly connected to the outer surface of the vehicle body 11.

The output end of the first motor 31 on the right side is fixedly connected to the first gear 32 by bolts. The first gear 32 is meshed with the second vehicle body 12 through the gear teeth 33.

[0032] A lifting column 36 is fixedly connected to the bottom of the arc-shaped plate 39. A rack 361 is fixedly connected to the front of the lifting column 36. A motor 34 is fixedly connected to the top of the inner wall of the second vehicle body 12. A gear 35 is fixedly connected to the left output end of the motor 34 by bolts. The back of the gear 35 meshes with the rack 361. The lifting column 36 slides through the second vehicle body 12 and extends into the interior. A limit tube 362 is slidably connected to the outer surface of the lifting column 36. The top of the limit tube 362 is fixedly connected to the top of the inner wall of the second vehicle body 12. When the motor 31 is started, it drives the gear 32 to rotate. The gear 32 drives the second vehicle body 12 through the gear teeth 33. 12 rotate together. When the arc plate 39 rotates to the damaged position, motor 1 31 is turned off, and motor 2 34 is started to drive gear 2 35 to rotate clockwise. Gear 2 35 drives the lifting column 36 to move upward. When the arc plate 39 contacts the damaged position, motor 2 34 is turned off. The resin in the storage tank 393 is sprayed onto the damaged position through the discharge pipe 392. At this time, the curing lamp 391 is turned on to irradiate the resin. After the resin solidifies, motor 2 34 is started to retract the arc plate 39 to the outer surface of the vehicle body 2 12. This method can repair any position inside the pipeline. The good flexibility can improve the repair efficiency.

[0033] The top of the arc plate 39 has a round hole, and the inner wall of the round hole is fixedly connected to the discharge pipe 392. The discharge pipe 392 passes through the vehicle body 2 12 and extends into the interior. The bottom of the discharge pipe 392 is fixedly connected to the storage tank 393. The front of the storage tank 393 is fixedly connected to the water pump 394. Several curing lamps 391 are fixedly connected to both the front and back of the arc plate 39.

[0034] A camera 111 is fixedly connected to the top of the vehicle body 11 on the left by bolts. An electric push rod 291 is fixedly connected to the bottom of the vehicle body 11 on the left. A mobile vehicle 292 is fixedly connected to the bottom output end of the electric push rod 291 by bolts. A high-pressure tank 13 is fixedly connected to the right side of the vehicle body 11 on the right. Several nozzles 131 are fixedly connected to the outer surface of the high-pressure tank 13.

[0035] One specific application of this embodiment is as follows: When repairing a pipe, the electric push rods 21 inside the left and right sides of the repair vehicle 1 extend, and the outer wall of the conical block 22 pushes the three support columns 24 away from each other, so that the roller 23 is in close contact with the inner wall of the pipe. The limiting block 26 and the limiting column 27 slide and limit the movement of the support column 24 with the outer surface of the vehicle body 11, so that the movement of the support column 24 is more stable and smooth. At this time, the electric push rod 291 is activated to drive the moving vehicle 292 to move downward until the wheels of the moving vehicle 292 contact the inner wall of the sewage pipe and stop. The moving vehicle 292 is activated to drive the repair vehicle 1 into the sewage pipe. After observing through the camera 111, the moving vehicle 292 is turned off after reaching the damaged position. Then the high pressure tank 13 is activated to spray water through the nozzle 131 to clean the dirt at the damaged position, so that the resin can repair better.

[0036] Then, continue moving the repair vehicle 1 until the arc plate 39 and the damaged position are on the same vertical plane. Then, close the moving vehicle 292. Next, start motor 1 31 to drive gear 1 32 to rotate clockwise or counterclockwise. Since gear teeth 33 are fixedly connected to the inner wall of vehicle body 2 12, and the inner wall of vehicle body 2 12 is rotatably connected to the outer surface of the circular block 38, vehicle body 2 12 will rotate clockwise or counterclockwise along with it. When the arc plate 39 rotates to the damaged position, close motor 1 31. At this time, start motor 2 34 to drive gear 2 35 to rotate clockwise. Gear 2 35 meshes with the front rack 361 of the lifting column 36, causing the lifting column 36 to move upwards. When the arc plate 39 contacts the damaged position, close motor 2 34. The resin in the storage tank 393 is then extracted by water pump 394 and discharged through the outlet... The material pipe 392 is sprayed onto the damaged area. The arc surface at the top of the curved plate 39 supports the resin. After the resin solidifies, it will form an arc surface that matches the inner wall of the sewage pipe. At this time, the curing lamp 391 is turned on to irradiate the resin. The curing lamp (LED ultraviolet UV curing lamp 395nm) emits ultraviolet rays of a specific wavelength. These ultraviolet rays can trigger the chemical reaction of the photoinitiator, thereby making the resin material solidify rapidly. After the resin solidifies, the motor 24 is started to rotate counterclockwise, so that the curved plate 39 is retracted to the outer surface of the vehicle body 212. At this time, the moving vehicle 292 is started to drive the repair vehicle 1 back to the starting point. After arriving at the starting point, the two electric push rods 21 are started to retract. After the bottom of the support column 24 loses support, the spring 28 uses elasticity to make the three support columns 24 move closer to each other, which facilitates subsequent storage and transportation.
