[0023] Embodiment:

[0024] When the device of the present utility model is used for pipeline docking, the inflatable plug assembly in the pipeline is placed at the first weld seam in advance according to the welding process requirements. The magnet ring 4 is installed on the inflation joint 4, and then the traction cable 8 and the inflation pipe 7 in the automatic traction wire reel 11 are inserted into the pipeline 1 and firmly connected to the inflatable plug assembly. Then, the first position signal generator 6 is fixed at a position near the second weld seam with a quick tightening strap. This position should ensure that when the inflatable plug assembly moves to the position required by the welding process, the magnet ring 4 can exactly make the first position signal generator 6 emit a signal. The second position signal generator 14 is installed at the end of the pipeline 1 and fixed with a quick tightening strap.

When the inflatable plug assembly moves to the position required by the second weld seam process, the magnetism of the magnet ring 4 triggers the first position signal generator 6 to act and output a signal. After the position signal receiving and processing unit 12 receives the signal, it sends a signal to cut off the power supply of the motor 116 to the drive power supply controller 13, and the automatic traction wire reel 11 stops running. The inflatable plug assembly stops at an appropriate position, starts to inflate the inflatable plug assembly, and then welds.
