The adjustment sleeve is movably sleeved on the outside of the extension rod, and a thread lock is installed on the front thread of the adjustment sleeve. Pin holes are equidistantly provided inside the extension rod. The thread lock is extended out of the pin hole by rotating the thread lock. By moving the position of the adjustment sleeve on the outside of the extension rod, the extension length of the extension rod can be adjusted, thereby adjusting the position height of the magnetic suction block 603 on the top of the adjustment sleeve, which is convenient for adjustment according to the aperture of the installation pipe, so that the magnetic suction block 603 fits the inner wall of the installation pipe; The horizontal position of the self-centering mechanism 6 can be adjusted by the translation mechanism 5, so as to facilitate adjustment according to the actual length of the installed pipeline, and the expansion frame 605 extends to the two pipeline docking interfaces respectively. The dual-axis motor 6012 is energized to drive the transmission assembly 604 to drive the expansion frame 605 to expand and fold and contract.

At this time, the other end of the self-centering mechanism 6 extends to the inside of the docking pipeline; Then, the double-axis motor 6012 is powered on to drive the threaded rod 6041 to rotate, and the rotating threaded rod 6041 drives the thread sleeve shaft frame 6044 to move horizontally. The horizontally moving thread sleeve shaft frame 6044 drives the expansion frame 605 to expand and move, and the expansion movement scissor frame 6051 drives the installation slot rod 6052 to expand. The expanded installation slot rod 6052 contacts the docking pipe and the docking interface of the lifting pipe through the contact wheel 6053, so as to adjust and correct the docking center of the docking interface of the lifting pipe and the docking pipe, achieve the effect of automatic centering, facilitate the precise positioning of the pipe docking interface, and facilitate the lifting pipe to continue to move and dock with the docking pipe through the rotatable contact wheel 6053; After the docking is completed, the servo motor A203 is powered on and runs to drive the travel wheel 205 to rotate in the opposite direction through the transmission gear set A204. The travel wheel 205 that rotates in the opposite direction rotates in the opposite direction on the track 202, thereby driving the moving seat 2 to move in the opposite direction. The moving seat 2 that moves in the opposite direction drives the operating platform 1 to move horizontally in the opposite direction through the support frame 103. The operating platform 1 that moves in the opposite direction drives the self-centering mechanism 6 on the inner wall of the pipeline through the translation mechanism 5, and moves out of the pipeline to assist in the next pipeline docking. By using this platform as a transportation carrier, the transportation connection between the crane and the mobile platform can be realized outside the influence range of the high-voltage line.
