Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the embodiment, Figure 1-4 A repairing device for deformation and collapse of plastic pipes is provided. The utility model comprises a movable plate 1, the inner side of the movable plate 1 is fixedly connected with a repairing cylinder 2, the top of the movable plate 1 is fixedly connected with a power motor 3, the bottom end of the movable plate 1 is fixedly connected with a power shell 4, the bottom end of the movable plate 1 is rotatably connected with a transmission threaded rod 5 located on the inner side of the power shell 4, the outer side of the transmission threaded rod 5 is fixedly connected with a transmission assembly 6, the outer side of the transmission threaded rod 5 is connected with a movable sleeve 7 through threaded transmission, the outer side of the movable sleeve 7 is fixedly connected with a limiting assembly 8, and the bottom end of the movable sleeve 7 is fixedly connected with a movable wheel 9.

[0027] Among them, the top end of the repair cylinder 2 is fixedly connected to the top repair plate 10 through fasteners, and the bottom end of the repair cylinder 2 is fixedly connected to the bottom repair plate 11. The outer sides of the top repair plate 10 and the bottom repair plate 11 are both set in arc shape.

[0028] The top repair plate 10 can be used to repair the collapsed part of the pipe wall, while the bottom repair plate 11 can provide good support for the entire device.

[0029] There are two power motors 3 and four power shells 4 , which are distributed at the bottom of the moving plate 1 in a rectangular array.

[0030] Among them, the transmission assembly 6 includes a first sprocket 61 fixedly connected to the outer side of the transmission threaded rod 5, and the bottom end of the output shaft of the power motor 3 is fixedly connected to the second sprocket 62. The outer sides of the first sprocket 61 and the second sprocket 62 are both transmission connected to the chain 63.

[0031] The power motor 3 will drive the second sprocket 62 to rotate, and then the first sprocket 61 will drive the transmission threaded rod 5 to rotate, so that the movable sleeve 7 will move up and down.

[0032] Among them, the limiting assembly 8 includes a limiting rod 81 fixedly connected to the outside of the movable sleeve 7, a limiting hole 82 is opened on the outside of the power shell 4, the outer side of the limiting rod 81 is slidingly connected to the inner side of the limiting hole 82, the outer side of the limiting rod 81 is fixedly connected with a protective block 83, and the limiting rod 81 extends to the outside of the power shell 4.

[0036] Working principle:

[0037] The repair cylinder 2 can be moved in the plastic pipe to be repaired through the moving wheel 9. When it moves to the position to be repaired, starting the power motor 3 will drive the second sprocket 62 to rotate, and then the chain 63 will drive the first sprocket 61 to rotate. As the transmission threaded rod 5 will rotate, the limit assembly 8 will limit the position of the moving sleeve 7, so that the moving sleeve 7 will move up, and the moving wheel 9 will move up, so that the bottom repair plate 11 will contact the inner surface wall of the plastic pipe, and the repair cylinder 2 will be started, so that the top repair plate 10 will repair the collapsed part of the plastic pipe.
