[0002] The current submarine cable laying construction generally has a long-distance shoal and intertidal zone construction section, which needs to rely on various heavy lifting equipment to drag and pull the submarine cable, and the current submarine cable diameter generally exceeds 200mm, corresponding to The minimum allowable bending radius is also gradually increasing. Therefore, during the towing and towing construction process of submarine cables in shoals and intertidal zones, the traditional single lifting point or non-rigid multi-lifting point towing method can easily cause the minimum bending radius of submarine cables to get out of control. causing damage to submarine cables

The invention relates to a modular submarine cable towing tool, which is composed of a submarine cable towing tool module and a module connecting pin. The two ends of the submarine cable towing tool module are respectively provided with connection ends, one of which is a concave connection groove, and the other connection end It is a convex connection groove, and both the concave connection groove and the convex connection groove are provided with pin holes. The upper and lower suspension rings are respectively provided on both sides of the submarine cable dragging tooling module. The upper suspension ring is used to connect with the traction wire rope of the traction equipment, and the lower suspension ring is for For connection to straps or cable ties or slings connected to submarine cables. The invention can limit the bending radius of the submarine cable in the towed area when the submarine cable is towed or towed on the beach, and protects the submarine cable at this position. The submarine cable towing tool can be disassembled into individual modules, which is convenient for transportation and carrying on the beach, and the overall length of the towing tool can be adjusted by increasing or decreasing the number of modules according to construction needs to adapt to different working conditions.
Description
technical field [0001] The invention relates to a bottom cable dragging device, in particular to a modular submarine cable dragging tool with the function of limiting bending of submarine cables, which is used for traction or position adjustment when laying submarine cables in shoals or intertidal zones. Background technique [0002] The current submarine cable laying construction generally has a long-distance shoal and intertidal zone construction section, which needs to rely on various heavy lifting equipment to drag and pull the submarine cable, and the current submarine cable diameter generally exceeds 200mm, corresponding to The minimum allowable bending radius is also gradually increasing. Therefore, during the towing and towing construction process of submarine cables in shoals and intertidal zones, the traditional single lifting point or non-rigid multi-lifting point towing method can easily cause the minimum bending radius of submarine cables to get out of control. ...
