The sixth step is to start the lateral drive device 40, and the piston rod of the lateral drive device 40 drives the left pipe clamping device to move to the right to approach the right pipe clamping device, so that the socket and the socket are connected.

In the seventh step, after the pipes are docked, hold one end for a while, and then release the left and right pressing mechanisms 23 at the same time, so that the two upper hoops 21 rise away from the lower hoops 31, and the pipes are released.

In the eighth step, adjust the lifting leg 11 to slowly descend until the descending distance reaches the radius of the docking pipe, then release the connection between the other end of the upper clamping device 20 and the lower clamping device 30, and then start the turning drive device 50 to make the upper clamping The device 20 is turned over with respect to the lower holding device 30, and after turning over, the pipe is pulled out to complete the docking.
