[0025] Working principle: When in use, the support wheel 106 can provide support force for the marine pipeline. Under the action of the external hydraulic source, the hydraulic cylinder 4 drives the clamping assembly 2 and the driving assembly 3 to approach the marine pipeline and clamp the marine pipeline, thereby facilitating welding. When it is necessary to drive the marine pipeline to rotate, the hydraulic cylinder 4 drives the clamping assembly 2 away from the marine pipeline under the action of the external hydraulic source.

The driving wheel 301 can drive the marine pipeline to rotate, thereby exposing the unwelded part of the marine pipeline to the welding position, and then the clamping assembly 2 is re-clamped, thereby facilitating welding.
