Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipe maintenance, in particular to a repairing device for reinforced concrete drainage pipes. Background Art

[0002] As we all know, reinforced concrete drainage pipes are made of steel bars and concrete. They are used for drainage and are widely used in municipal and water conservancy projects. Water can flow through them and they bear soil pressure on the outside. During long-term use, various situations will cause them to need repair. For example, the inner wall is worn by the water flow in the pipe, especially the high-speed water flow with debris. In the complex underground environment, the acid and alkali corrosion of the soil and the erosion of groundwater will damage the concrete and steel bars. In addition, the vibration caused by the ground load may cause cracks in the pipe body.

[0003] Most existing municipal drainage pipes rely on gravity for drainage. When a large amount of solid waste accumulates in the pipes, it is very easy to cause blockage. Furthermore, the pipes are prone to rupture, increasing construction costs and making daily maintenance of these pipes inconvenient.

[0004] The existing patent (publication number: CN215406416U) discloses a maintenance device for a drainage pipe, which is achieved by arranging multiple bases and fixed bases on a base, wherein the fixed bases are fixedly installed between the bases, and a support plate is fixedly installed on the upper end of the fixed base, and an arc groove is provided inside the support plate that cooperates with the pipe body to ensure the stability of the drainage pipe; a drainage mechanism is installed on the pipe body, and the drainage mechanism includes an arc-shaped drainage cavity, and a quick drainage mechanism and a control mechanism are installed on the arc-shaped drainage cavity. The control mechanism is electrically connected to the quick drainage mechanism and is used to control the working state of the quick drainage mechanism. The other end of the control mechanism is connected to the base, so as to effectively discharge the solid waste inside the pipe, prevent the pipe from being blocked, and avoid relying solely on gravity to descend. It has a fast drainage speed and high efficiency, which is conducive to promotion.

[0005] In response to the above problems, existing patents provide solutions. However, when repairing reinforced concrete drainage pipes, due to the lack of a multi-directional self-propelled limiting structure that can adapt to the inside and outside of the drainage pipes, it is impossible to perform multi-directional repairs on the inside and outside of the drainage pipes, which reduces the flexibility of repairing the inside and outside of the drainage pipes.

[0031] In this embodiment: by setting up a movable hydraulic rod 1, a repair mechanism 2 and a feeding pipe 3, the movable hydraulic rod 1 can support and limit the position of the servo motor 21, and the servo motor 21 drives the adjusting screw 22 to rotate, thereby driving the traction plate 24 to move back and forth along the guide rod 23, thereby driving the repair nozzle 25 to move, and allowing the repair nozzle 25 to move to the required repair part of the drain pipe, so that the required repair part can be repaired by the repair material delivered by the feeding pipe 3, thereby improving the flexibility when repairing the required repair part of the drain pipe.

[0032] Specifically, such as Figure 4 As shown, the displacement mechanism 4 includes an adjusting component 41 and a positioning component 42 .

Then the adjusting hydraulic rod 412 on the rear side of the mobile hydraulic rod 1 will lower the positioning assembly 42 until the positioning assembly 42 contacts the drain pipe. Then the positioning assembly 42 on the rear side of the mobile hydraulic rod 1 will be adsorbed with the drain pipe. Then the positioning assembly 42 on the front side of the mobile hydraulic rod 1 will stop being adsorbed with the drain pipe. Then the adjusting hydraulic rod 412 on the front side of the mobile hydraulic rod 1 will drive the positioning assembly 42 to lift. Then the mobile hydraulic rod 1 will extend and drive the displacement mechanism on the front side. 4 moves forward, and then the adjusting hydraulic rod 412 on the front side of the hydraulic rod 1 will lower the positioning component 42, and then the positioning component 42 will be adsorbed with the drain pipe. When the left and right sides are required, the positioning component 42 on the rear side of the hydraulic rod 1 will stop being adsorbed with the drain pipe, and then the adjusting motor 411 on the rear side of the hydraulic rod 1 will drive the adjusting hydraulic rod 412 to rotate to the required position, and then the positioning component 42 will be adsorbed with the drain pipe again, and then the positioning component 42 on the front side of the hydraulic rod 1 will stop being adsorbed with the drain pipe, and then the front side of the hydraulic rod 1 will be moved forward. The adjusting motor 411 on the side will drive the adjusting hydraulic rod 412 to rotate the positioning component 42 in the required direction of movement until the positioning component 42 moves to the required position and is adsorbed on the drain pipe. Then the feeding pipe 3 is connected to the repair material conveying equipment, and the feeding pipe 3 will convey the repair material to the repair nozzle 25. Then the servo motor 21 will drive the adjusting screw 22 to move until the adjusting screw 22 drives the traction plate 24 to move the repair nozzle 25 along the guide rod 23 to the required repair location. The repair nozzle 25 will convey the repair material to the required repair location.
