Description

Technical Field

[0001] The utility model relates to a pipeline welding support device, in particular to a large-diameter heating pipeline crossing construction pipe opening welding support device, belonging to the technical field of pipeline welding. Background Art

[0002] During the heating pipe crossing construction, it is necessary to lay the heating pipe in the trench and weld the interface of the heating pipe. In this process, the two pipes need to be lifted to a certain height before the pipe mouths can be welded. Since the pipes are heavy, in order to lift the pipes smoothly, the staff will cross the sticks at the bottom of the pipes and lift the ends of the sticks until the pipes are lifted to the required height. The welding workers can then quickly weld the pipe mouths. However, this construction method is time-consuming and labor-intensive, and the manual lifting of the pipes cannot guarantee the stability of the pipes during welding, which seriously affects the accuracy of the pipe interface welding.
