[0034] like Figures 1 to 6 As shown, the embodiment of the utility model provides a drainage pipe collapse deformation pretreatment jacking expansion device, including an endoscopic crawling robot 1, the top of the endoscopic crawling robot 1 is fixedly connected to a support arm 2, and four groups of jacking mechanisms 3 are symmetrically distributed at the ends of the support arm 2, wherein the two groups of jacking mechanisms 3 arranged horizontally are called upper and lower jacking mechanisms, and the two groups arranged vertically are called left and right jacking mechanisms, and the outer sleeve of the jacking mechanism 3 is provided with a jacking expansion structure 4, and the extension of the jacking mechanism 3 can drive the jacking expansion structure 4 to expand, and the jacking expansion structure 4 has a self-locking structure, and by setting the jacking mechanism 3 and the jacking expansion structure 4, when in use, the telescopic function of the jacking mechanism 3 is utilized to drive The top expansion structure 4 is expanded, and the outer diameter of the circular ring formed after the top expansion structure 4 is expanded will be the same as the inner diameter of the collapsed pipe. The self-locking mechanism of the top expansion structure 4 can automatically lock the top expansion structure 4 after the expansion is completed. The endoscopic crawling robot 1 is an intelligent automatic mobile detection equipment specially used for pipeline repair. It is a mature technical means in the field of pipeline repair. The end of the support arm 2 is equipped with a sensor used in conjunction with the endoscopic crawling robot 1 to determine the position of the top expansion structure 4. The top expansion structure 4 is transported to the collapsed part of the pipe by the endoscopic crawling robot 1. During the expansion process, the top expansion structure 4 will lift up the collapsed part of the pipe, which is convenient for later pipeline repair.

[0035] like Figure 2 and Figure 3 As shown, the top expansion structure 4 includes four groups of top expansion plates 5, two groups of top expansion plates 5 are paired and symmetrically distributed, and the adjacent ends of the paired top expansion plates 5 are slidably connected by locking connecting plates 6, and the end of the top expansion plate 5 away from the locking connecting plate 6 is rotatably connected with a rotating connecting plate 7, and the two adjacent groups of rotating connecting plates 7 are rotatably connected by connecting pieces 8. The four groups of top expansion plates 5 are annularly connected by the locking connecting plates 6, the rotating connecting plates 7 and the connecting pieces 8. The top expansion plate 5 is an arc-shaped steel plate structure, and connecting grooves 10 are provided on the end surfaces of both ends of the top expansion plate 5. One end of the rotating connecting plate 7 is embedded in the connecting groove 10 and connected to the rotating shaft of the top expansion plate 5. Sliding grooves are provided on the opposite side walls of the top expansion plate 5, and the sliding grooves are close to the locking connecting plate 6. Locking grooves 12 are respectively provided on both sides of the inner wall of the connecting groove 10 at the other end of the top expansion plate 5, and locking spring plates 13 are fixedly connected inside the locking groove 12. The locking connecting plate 6 can be locked with the adjacent top expansion plate 5 through the locking spring plates 13.

[0036] like Figures 2 to 5 As shown, the locking spring piece 13 includes a guide portion 16 fixedly connected to the inner wall of the locking groove 12, one side of the guide portion 16 is a locking portion 15, one side of the locking portion 15 is a recessed portion 14, the locking connecting plate 6 is an arc-shaped steel plate structure, and sliding piles 17 are fixedly connected to the four corners of the outer wall of the locking connecting plate 6, respectively, and the sliding piles 17 are adapted to the sliding groove 11. When the locking connecting plate 6 is connected to the top expansion plate 5, the sliding piles 17 are embedded in the corresponding sliding groove 11 and are slidably connected. A locking back plate 18 is fixedly connected to the outer wall of the locking connecting plate 6. The locking back plate 18 is an arc-shaped steel plate structure and its length is shorter than the locking connecting plate 6. The width of the locking back plate 18 is less than the width of the connecting groove 10. A snap-in groove 9 is provided in the middle of the inner wall of the locking connecting plate 6, and the telescopic end of the lifting mechanism 3 is connected. It is connected to the corresponding locking connecting plate 6 through the snap-fit ​​groove 9, and locking piles 19 are fixedly connected at both ends of the side walls of the locking back plate 18, and the locking piles 19 are adapted to the recessed portion 14. By arranging the locking spring piece 13 and the locking pile 19, when the locking connecting plate 6 and the top expansion plate 5 are locked, the corresponding locking pile 19 passes over the locking portion 15 via the guide portion 16 and enters the recessed portion 14, and in this process, the locking portion 15 is compressed and deformed and recovers its deformation after the locking pile 19 enters the recessed portion 14. The arched locking portion 15 can prevent the recessed portion 14 from detaching from the locking groove 12, thereby realizing the self-locking function between the top expansion plate 5 and the locking connecting plate 6. After the top expansion plate 5 and the locking connecting plate 6 are locked, the top expansion structure 4 expands into a circular ring as a whole and self-locks into a stable structure.

[0037] like Figure 1 and Figure 6 As shown, the two ends of one side wall of the connecting member 8 are fixedly connected with connecting blocks 20 respectively, and the connecting member 8 is connected to the rotating shaft of the end of the adjacent rotating connecting plate 7 through the connecting block 20, and the other side wall of the connecting member 8 is fixedly connected with a clamping groove 9, which is a blind groove structure and has a certain taper. The outer groove diameter of the clamping groove 9 is smaller than the bottom groove diameter. By setting the clamping groove 9, when the telescopic end of the jacking mechanism 3 is embedded in the clamping groove 9, the outer diameter of the clamping groove 9 is connected with the telescopic end by interference fit, thereby clamping the telescopic end. During use, the telescopic end of the jacking mechanism 3 extends to push the locking connecting plate 6 and the connecting member 8 connected to the clamping groove 9, and drives the top expansion plate 5, the locking connecting plate 6 and the rotating connecting plate 7 to move gradually to form a circular shape and lock.

[0038] The working principle of the utility model is as follows: when in use, the top expansion structure 4 is first installed on the endoscope crawling robot 1 and connected with the corresponding jacking mechanism 3, that is, the telescopic ends of the four groups of jacking mechanisms 3 are respectively connected with the corresponding clamping grooves 9, and the telescopic ends of the jacking mechanisms 3 are contracted. At this time, the top expansion structure 4 is a non-circular closed structure, and then the endoscope crawling robot 1 is placed in the pipeline repair opening. The endoscope crawling robot 1 will automatically carry the top expansion structure 4 to move to the collapsed part of the pipeline, and control the telescopic end of the jacking mechanism 3 to extend, and push the corresponding locking connection The plate 6 and the connecting member 8 move horizontally or vertically respectively, and at the same time drive the top expansion plate 5 and the rotating connecting plate 7 to move, wherein the left and right jacking mechanisms push the connecting member 8 to move, and the upper and lower jacking mechanisms push the locking connecting plate 6 to move, and by controlling the elongation of the upper and lower jacking mechanisms to be different from that of the left and right jacking mechanisms, the elongation of the left and right jacking mechanisms is greater than that of the upper and lower jacking mechanisms, so that when the left and right jacking mechanisms push the connecting member 8 to move, the two sets of rotating connecting plates 7 originally folded together will unfold, so that the rotating connecting plate 7 and the top expansion plate 5 are spliced ​​into a smooth connection. The rotating connecting plate 7 pushes the top expansion plate 5 to move toward the locking connecting plate 6 during the unfolding process, so that the locking pile 19 gradually approaches the corresponding locking groove 12, and finally the locking pile 19 passes over the locking portion 15 through the guide portion 16 and enters the recessed portion 14. In this process, the locking portion 15 is compressed and deformed and recovers its deformation after the locking pile 19 enters the recessed portion 14. The arched locking portion 15 can prevent the recessed portion 14 from detaching from the locking groove 12, thereby realizing the self-locking function between the top expansion plate 5 and the locking connecting plate 6. After the top expansion plate 5 is locked with the locking connecting plate 6, the top expansion structure 4 is expanded as a whole into a circular ring and locked, and the four sets of lifting mechanisms 3 respectively support the corresponding locking connecting plates 6 and connecting pieces 8, so that the formed circular ring is stable. After the top expansion structure 4 is expanded, the collapsed pipe part is lifted up, and the outer wall of the top expansion structure 4 is tightly attached to the inner wall of the pipe, thereby reinforcing the pipe to facilitate the later repair of the pipe. After the top expansion structure 4 is expanded outward and locked, the telescopic end of the lifting mechanism 3 is retracted and withdrawn from the clamping groove 9, and the endoscopic crawling robot 1 can withdraw from the pipe.
