[0002] In water supply engineering construction, various water pipes need to be installed and go through processes such as welding, cutting, and bending. Due to bumps and other reasons, the pipe openings often undergo deformation, resulting in irregular roundness and affecting the connection between pipes. This requires the use of pipe opening repair devices to restore the roundness of the pipe openings.

[0003] Chinese Patent No. CN213671205U discloses a repair device for pipe openings in water supply projects, including a mounting base, a rotating worktable, and a main controller. The main controller is mounted on the mounting base. First sliding bases are symmetrically arranged on the upper ends of the two side walls of the mounting base. A second sliding base is arranged on the upper surface of the mounting base between the two side walls. Rolling grooves are provided on both the front and rear surfaces of the rotating worktable. The rolling grooves are arc-shaped depressions. The two first and second sliding bases are connected to the rotating worktable via the rolling grooves. External spherical bearings are provided between the first and second sliding bases and the rolling grooves. The bearings are respectively installed on the inner side walls of the first sliding base and the second sliding base. The outer side wall of the rotating worktable is provided with a groove. Although this kind of pipe opening repair equipment for water supply projects has excellent effects such as low construction difficulty, low labor intensity, no impact on the use effect and guarantee of pipe service life during pipe correction, this kind of pipe opening repair equipment for water supply projects requires the use of an external clamping device before repair.

[0015] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0016] This application employs a drive assembly, a support assembly, a toothed ring assembly, a support plate, a sliding rod assembly, a snap-fit ​​assembly, multiple telescopic extrusion roller assemblies, and multiple telescopic extrusion block assemblies; the drive assembly is positioned below the toothed ring assembly, and the output end of the drive assembly is meshed with the outer surface of the toothed ring assembly; the support assembly is slidably connected to both sides of the toothed ring assembly, so that when the output end of the drive assembly rotates, it can drive the toothed ring assembly to rotate and slide relative to the support assembly;

[0038] This application provides a repair method for a water supply engineering pipe opening repair device, comprising: inserting the pipe opening to be repaired into the toothed ring assembly 3, i.e., first pressing the inner wall of the pipe opening against the extrusion block 82 and the outer wall of the pipe opening against the roller 73, while placing the pipe opening body on the bending frame 103, and then raising the pipe opening body to an appropriate position by rotating the screw 102; then controlling the action of multiple telescopic extrusion block assemblies 8, so that the output ends of the multiple telescopic extrusion block assemblies 8 contact and extrude the inner wall of the pipe opening to be repaired, i.e., controlling the second telescopic part 81 to drive the extrusion block 82 to extrude and tighten the inner wall of the pipe opening, thereby fixing the pipe opening; then snapping the snap-fit ​​assembly 6 and the sliding rod assembly 5 together and fixing them to the top of the support plate 4, i.e. The top of the insert plate 63 is inserted into the right angle of the bent plate 61, and the insert plate 63 is pressed against the bent plate 61 by the second elastic element 92 to ensure that the sliding rod assembly 5 does not move axially. Then, the multiple telescopic extrusion roller assemblies 7 are controlled to move, so that the output ends of the multiple telescopic extrusion roller assemblies 7 contact and extrude to the outer wall of the pipe opening to be repaired. That is, the first telescopic part 71 is controlled to drive the roller 73 to move, thereby extruding the outer wall of the pipe opening. Finally, the drive assembly 1 is controlled to move, thereby driving the toothed ring assembly 3 to rotate, that is, driving the ring body 31 to rotate, and finally driving the multiple telescopic extrusion roller assemblies 7 to rotate synchronously. The roller 73 continuously extrudes the outer wall of the pipe opening, thereby extruding and repairing the deformed part of the outer wall of the pipe opening, and solving the problem of the pipe opening being difficult to connect.

[0039] In this embodiment, when the extrusion block 82 is damaged due to long-term use, the operator only needs to push the insert plate 63 downwards. The insert plate 63 then slides on the surface of the support plate 4. At the same time, the insert plate 63 drives the side plate 64 to pull the first elastic element 66 until the insert plate 63 leaves the inside of the bent plate 61. At this time, the bent plate 61 loses its fixation, and then the slide rod 51 can be pulled outwards. The slide rod 51 then drives the column 52 to move until the slide rod 51 is completely disengaged from the through groove 41. At this time, the extrusion block 82 can be removed, and then the entire extrusion block 82 can be replaced. When installing the new extrusion block 82, the operator only needs to insert the slide rod 51 into the through groove 41. After it is fully inserted, the insert plate 63 is released. Then, due to the restoring force of the first elastic element 66, the first elastic element 66 pulls the side plate 64 to move. The side plate 64 then drives the insert plate 63 to move until the insert plate 63 abuts against the inside of the bent plate 61. At this time, the slide rod assembly 5 and the extrusion block 82 are completely replaced, which improves the maintenance efficiency of the extrusion block 82 and avoids affecting the pipeline connection work.

[0040] In this embodiment, when rust appears on the extrusion block 82, the worker can hold the handle 94 and push the disc 91. The disc 91 then slides on the surface of the slide rod 51, and at the same time, the disc 91 drives the polishing stone 93 to move until the polishing stone 93 rubs against the surface of the extrusion block 82. At this time, by repeatedly pushing the handle 94, the surface of the extrusion block 82 can be polished. After polishing, the handle 94 is released, and then due to the elasticity of the second elastic element 92, the second elastic element 92 drives the disc 91 to slide on the surface of the slide rod 51 until the disc 91 and the extrusion block 82 return to their original positions. In this embodiment, the polishing stone 93 can be set to polish the extrusion block 82 when rust appears, thereby improving the smoothness of the surface of the extrusion block 82, preventing the extrusion block 82 from scratching the inner wall of the pipe, and effectively protecting the pipe. When the pipe opening needs to be repaired, it can reduce the physical exertion of the workers.
