[0030] The rotating assembly includes a crossbeam and a first drive assembly. Two gear mounting plates are movably mounted on the crossbeam. Each gear mounting plate is provided with a rotatable arc segment and a first drive assembly that can drive the arc segment to rotate. The length direction of the crossbeam is perpendicular to the extension direction of the pipe to reduce the displacement distance of the two gear mounting plates.

[0031] There is a first space between the two gear mounting plates for the pipe to pass through, and the arc segment rotates around the first space under the drive of the first drive member. After the winding machine is installed on the in-service pipe, the arc segment is moved to the working position by moving the two gear mounting plates.

[0032] The winding assembly includes a bracket and a turntable. The bracket is fixedly mounted on the arc-shaped segment, and the turntable is rotatably mounted on the bracket.

[0033] The turntable is used to mount optical fibers to be wound. Different materials to be wound can also be set according to different needs on the pipeline. In order to improve work efficiency, the turntable and the bracket can be made detachable so that after the optical fibers on one turntable are wound, the turntable can be replaced directly for continuous operation, thereby improving the winding efficiency.

[0034] After the rotary disc is installed, the first driving assembly drives the arc-shaped segment to rotate relative to the gear mounting plate, that is, the arc-shaped segment rotates around the first space, and the rotary disc on the arc-shaped segment also rotates around the first space, the fiber end on the rotary disc is fixed on the outer sidewall of the pipeline when the winding machine is arranged on the pipeline, and the fiber end is dragged to rotate relative to the rotation under the driving of the first driving assembly, the fiber is gradually pulled out, and the fiber is spirally wound on the pipeline due to the rotation of the arc-shaped segment.

[0039] Further, on the basis of the above-mentioned embodiment, bearings are provided between the arc-shaped segments and the gear mounting plates to maintain the rotatability of the arc-shaped segments and prevent the arc-shaped segments from being separated from the gear mounting plates. It is worth noting that the two gear mounting plates are close to each other, and after the two arc-shaped segments are enclosed to form a complete ring, the bearings on the two gear mounting plates can be enclosed to form a complete bearing. When the arc-shaped segment on one gear mounting plate rotates to the other gear mounting plate, the stability of the arc-shaped segment is maintained.
