Description

Technical Field

[0001] The utility model relates to the field of submarine cable detwist wheels, in particular to a submarine cable reversal detwist wheel. Background Art

[0002] In the process of offshore wind power construction on offshore oil platforms, the laying and laying of submarine cables are indispensable links. Submarine cables are usually large in diameter and long in length, so they need to be wound on cable storage drums for shipment to cable laying vessels, which then transport the submarine cables to the target sea area for laying. Torsion will be generated during the transportation and winding of submarine cables, especially during the process of transporting the submarine cable drums by horizontal conveyor belts, which is the main way to generate torque inside the submarine cable. In order to overcome the torque, a detwisting wheel is needed to eliminate the torque inside the submarine cable.

[0003] However, most of the traditional submarine cable unwinding wheels are not equipped with slots for stacking submarine cables. Therefore, during the work of recovering the submarine cable, the submarine cable stacked on the relatively smooth roller may slip or even slide off the roller frame, thus affecting the recovery of the submarine cable. It is also easy to cause the edges of the submarine cable and the roller frame to wear, thus affecting the service life of the submarine cable. At the same time, the traditional submarine cable unwinding wheel has a relatively simple rotation method, mostly using a single motor as the power or hydraulics as the power. Due to the high weight of the submarine cable, it may be too heavy in actual use, thus affecting the service life of the power device.

[0004] Therefore, those skilled in the art provide a submarine cable reversal and detwist wheel to solve the problems raised in the above background technology. Utility Model Content

By starting a servo motor, a rotating rod is driven to rotate, and a driving gear and a driven gear plate are driven to rotate synchronously, thereby driving the second chassis to rotate, so as to retract and release the submarine cable. At the same time, the sliding wheel can slide along the pulley groove on the upper surface of the first chassis, thereby achieving the purpose of reducing the workload of the servo motor and prolonging the service life of the servo motor.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0014] Furthermore, a plurality of supporting legs are fixedly connected to the lower surface of the first chassis, and a height gauge is fixedly connected to the outer wall of the front end of the column;

[0015] Through the above technical solution, the first chassis is made more stable by the supporting legs, and the staff can grasp the height of the stacked submarine cables by the height gauge.

[0018] Furthermore, a first bearing is fixedly connected to the middle of the driven gear plate, and two second bearings are fixedly connected to the middle of the second chassis;

[0019] Through the above technical solution, the driven gear plate and the second chassis can be rotated through the first bearing and the second bearing.

[0020] Furthermore, the inner walls of the first bearing and the second bearing are both fixedly connected to the outer wall of the column;

[0021] Through the above technical solution, the connection between the first bearing and the second bearing and the column can prevent the column from being affected by rotation.

[0022] Furthermore, the driving gear and the driven gear plate are meshed with each other, and a rain cover is fixedly connected to the upper surface of the base;

[0023] Through the above technical solution, the connection between the driving gear and the driven gear plate is made more secure through meshing, and the driving gear can be protected from rain erosion through the rain cover.
