Technical Field

The utility model relates to the technical field of submarine cable laying construction equipment, in particular to a submarine cable lifting lashing rope and a lashing rope assembly.

Background

In constructing offshore oil drilling platforms, it is necessary to lift sea cables laid via the seafloor onto the work platform. Typically the sea cable will be pulled by a pull rope and lifted via a J-tube onto the work platform.

Since the end of the sea cable is located in the deep sea, most of the time of the sea cable lifting operation is spent on the binding operation of the sea cable and the hauling rope. And because the variety and the quantity of the submarine cables are more, a plurality of submarine cables with different functions are generally fixed in one pipe sleeve at one time during operation. The end part of the pipe sleeve is arranged in a conical shape, a hanging ring and other structures convenient to connect are arranged at the end part, and then the pipe sleeve is pulled by the traction rope to realize the lifting of the submarine cable.

In practice the inventors have found that the diameter of the pipe sleeve itself is fixed and is therefore not suitable for lifting of different numbers of sea cables, and that the wall thickness of the pipe sleeve itself is large, directly increasing the outer diameter of the whole sea cable assembly to be lifted. Because the J-shaped pipe is arranged in the seawater body for a long time, marine organisms such as clams and the like are often attached to the inner wall of the J-shaped pipe, the inner diameter of the J-shaped pipe is reduced, the pipe sleeve with the large diameter is very easy to clamp in the J-shaped pipe, the lifting operation is failed, and the obstacle removing work is very complicated and difficult.

Therefore, how to stably and firmly bind numerous submarine cables without obviously increasing the overall outer diameter is a current problem to be solved urgently.
