Description

Technical Field

[0001] This utility model relates to a cable gear un-twist mechanism, belonging to the field of equipment for submarine cable laying. Background Technology

[0002] The construction of offshore wind power projects requires the use of a large number of cables, and cable laying and reeling are essential steps in the process. During cable cabling, stretching, and movement, significant internal torsional stress is often generated. This stress can lead to structural damage or performance degradation of the cable. To alleviate or mitigate this internal torsion, a de-torsion roller is needed before cable laying. The stability of the de-torsion operation has a significant impact on cable performance and also shortens cable life due to long-term exposure to sea winds and humid environments. Therefore, improving the operational stability and extending the lifespan of the de-torsion roller is a crucial issue that urgently needs to be addressed. Utility Model Content

The drive motor is located at the center of the two lifting lugs, and a driving wheel is installed at its output end. A driven wheel is installed on the rotating body. The transmission chain meshes with the driving wheel and the driven wheel. The drive motor adopts a cycloidal pinwheel reducer.

[0005] This utility model adopts a disc-type unwinding mechanism and a transmission chain. Its drive motor is set on the top of the unwinding mechanism. Its structure is more multi-stage, the transmission structure is more compact, and it can achieve a larger unwinding stroke, which can effectively save installation space.

[0008] Further, or optionally, the unwinding wheel is internally provided with radially arranged cross-shaped brackets, with circumferential support columns between each bracket, and an outer ring groove parallel to the unwinding wheel brackets.
