DETAILED DESCRIPTION

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] Example 1:

[0033] like Figure 1As shown in Figure 3: A pipe deformation repair device includes a fixing plate 1. The fixing plate 1 is bolted to a fixing seat 2 and the cylinder body of a hydraulic cylinder 4. A parallel support assembly 3 is installed on the fixing seat 2. The parallel support assembly 3 includes a first support arm 31 and a second support arm 32 arranged parallel to each other. One end of the first support arm 31 and the second support arm 32 is rotatably connected to a first connecting seat 34 via a pin. The first connecting seat 34 is installed on the fixing seat 2. The other end of the first support arm 31 and the second support arm 32 is rotatably connected to a second connecting seat 35 via a pin. The second connecting seat 35 is installed on an inner expansion plate 33. The second support arm 32 is rotatably connected to a second supporting seat 35 via a pin. One end of the support arm 6 and the other end of the support arm 6 are rotatably connected to the connecting assembly 5 via a pin. The connecting assembly 5 is mounted on the piston rod of the hydraulic cylinder 4. The connecting assembly 5 and the fixing plate 1 are respectively connected to the two ends of the protective cover 7. The protective cover 7 is fitted on the outside of the piston rod of the hydraulic cylinder 4. When the hydraulic cylinder 4 extends or retracts, the support arm 6 drives the parallel quadrilateral linkage structure composed of the parallel support assembly 3 and the fixing seat 2 to move, thereby stably supporting the collapsed and deformed pipe for quick and convenient pipe repair work. The fixing seat 2 includes an end plate 21 and a connecting column 22. There are two end plates 21, which are respectively fixed at both ends of the connecting column 22. The end plates 21 are through-holes. A through hole is provided for fitting onto the outer side of the cylinder body of the hydraulic cylinder 4. Multiple connecting columns 22 are evenly arranged around the through holes on the end plate 21. The fixing seat 2 is securely connected to the flange on the cylinder body of the hydraulic cylinder 4 via bolts. The multiple connecting columns 22 provide stable support for the parallel support assembly 3. The inner expansion plate 33 has an arc-shaped structure; its arc surface effectively conforms to the inner wall of the supporting pipe. Multiple inner expansion plates 33 are equidistantly spaced around the axis of the hydraulic cylinder 4. The symmetrically arranged inner expansion plates 33 can be extended outwards to stably support the pipe. The protective cover 7 is a rubber corrugated pipe structure. The protective cover 7 extends and retracts synchronously with the extension and retraction of the oil cylinder 4, effectively preventing foreign objects from contaminating and corroding the piston rod of the oil cylinder 4. The connecting component 5 includes an internal threaded head 51 and a connecting sleeve 52. The fixing plate 1 is threadedly connected to the piston rod of the oil cylinder 4. The internal threaded head 51 can be conveniently installed on the oil cylinder 4 through the threaded structure. The curved side of the internal threaded head 51 is provided with an annular groove for fitting and mounting the connecting sleeve 52. The connecting sleeve 52 is composed of two arc-shaped plates of the same size, and the two arc-shaped plates are bolted together and mounted on the outside of the internal threaded head 51. The connecting sleeve 52 can be conveniently and stably installed on the outside of the internal threaded head 51.

[0034] The working principle of this technical solution is as follows: When it is necessary to repair the deformed pipe, the hydraulic cylinder 4 is activated. The piston rod of the hydraulic cylinder 4 extends or retracts, driving the connecting assembly 5 to move. Since the connecting assembly 5 is connected to the support arm 6 through a pin, and the support arm 6 is rotatably connected to the second support arm 32 through a pin, the linear motion of the piston rod of the hydraulic cylinder 4 is converted into the swing of the support arm 6. The swing of the support arm 6 drives the parallel support assembly 3 to move. Because the first support arm 31 and the second support arm 32 in the parallel support assembly 3 are rotatably connected to the fixed seat 2 through the first connecting seat 34. The inner expansion plate 33 is rotatably connected to the connecting seat 2 35, and the support arm 1 31 and support arm 2 32 are parallel to each other. Therefore, the parallel support assembly 3 and the fixed seat 2 form a parallelogram linkage structure. Under the drive of the support arm 6, the parallelogram linkage structure moves, causing the inner expansion plate 33 to move outward or retract inward. When the inner expansion plate 33 moves outward, multiple arc-shaped inner expansion plates 33 that are equidistantly arranged around the axis of the oil cylinder 4 are simultaneously supported, adhering to the inner wall of the pipe, and stably supporting the collapsed and deformed pipe, providing stable support for subsequent repair work.
