[0032] Jacking assembly includes transmission shaft 12, and the two ends of transmission shaft 12 are rotatably connected on the proximal side of two transmission rods 10, to ensure that transmission shaft 12 can stably and flexibly rotate, to drive the movement of lifting block 13.The outer wall of transmission shaft 12 is fixedly connected with lifting block 13, and the lifting of jacking column 3 is realized by the swing of lifting block 13, and the outer wall of lifting block 13 is slidably connected in the inside of one movable slot, to provide a movable space and movement support base for the movement of lifting block 13.The outer wall of jacking column 3 is fixedly connected with multiple chucks 7, and chucks 7 are evenly distributed on the outer wall of jacking column 3, to cooperate with lifting block 13, realize the lifting function of jacking column 3, and the bottom outer wall of chuck 7 is in contact with the top outer wall of lifting block 13, when lifting block 13 moves upward, the top outer wall thereof will be in contact with the bottom outer wall of chuck 7, to push chuck 7 to move upward.Conversely, when lifting block 13 moves downward, it will slide on the circular surface of next chuck 7 until sliding to the bottom of next chuck 7.The outer wall of telescopic pipeline 2 is fixedly connected with locking assembly for locking the telescopic length of telescopic pipeline 2, and locking assembly can lock the telescopic length of telescopic pipeline 2, to ensure that it remains stable during working process.

[0033] The locking assembly comprises a locking box 14 for protecting the internal working elements and providing a mounting base for the internal working elements. One side of the locking box 14 is fixedly connected to the outer wall of the telescopic pipeline 2, and the inner wall of the locking box 14 is fixedly connected with a rotating shaft two 15, the outer wall of the rotating shaft two 15 is rotatably connected with a locking block 16, the rotating shaft two 15 serves as the rotation center of the locking block 16, which can ensure the stability of the locking block 16 during locking and unlocking, while the locking block 16 can rotate freely around the rotating shaft two 15 to realize the locking and unlocking of the telescopic length of the telescopic pipeline 2. The top outer wall of one end of the locking block 16 is in contact with the bottom outer wall of the chuck 7, and the outer wall of the locking block 16 is slidingly connected in the other movable groove.

When the lifting block 13 moves upward, the chuck 7 moves upward, and when the lifting block 13 moves downward, the lifting block 13 slides on the arc surface of the next chuck 7 until it slides to the bottom of the next chuck 7. After the chuck 7 moves upward, the locking block 16 in contact with it rotates around the rotating shaft two 15, thereby pressing the deformation segment of the elastic column 17, and when the locking block 16 moves to the bottom of the chuck 7, the deformation segment restores the deformation to drive the locking block 16 to rotate in the opposite direction, thereby supporting the chuck 7, so that the chuck 7 can remain stable after lifting, thereby realizing the lifting of the jacking column 3, and the locking column can be unlocked by being pushed upward, so that the chuck 7 can descend due to gravity, thereby realizing the lifting and lowering of the jacking column 3, i.e. the telescopic length of the telescopic pipeline 2. When the telescopic pipeline 2 telescopes, upward pressure is generated to drive the flange interface 5 to press the transformer oil pipe interface upward, and because the diameter of the outer frame 1 is smaller than the diameter of the flange interface 5, the outer frame 1 and the flange interface 5 cooperate to complete the connection and fixation of the transformer oil pipe.
