Abstract

The invention relates to a modular submarine cable dragging tool which is composed of submarine cable dragging tool modules and module connecting plug pins. Two ends of each submarine cable dragging tool module are provided with connecting ends respectively, one connecting end is a concave connecting groove, the other connecting end is a convex connecting groove, and the concave connecting grooveand the convex connecting groove are each provided with a plug pin hole. An upper hanging ring and a lower hanging ring are arranged on the two sides of each submarine cable dragging tool module respectively, the upper hanging ring is used for being connected with a traction steel wire rope of traction equipment, and the lower hanging ring is used for being connected with a binding belt or a binding rope or a hanging rope connected with a submarine cable. When the submarine cable is subjected to mud flat traction or towing operation, the bending radius of the submarine cable in a towed area can be limited, and the effect of protecting the submarine cable at the position is achieved. The submarine cable dragging tool can be disassembled into independent modules, transportation and carryingon a mud flat are facilitated, the overall length of the dragging tool can be adjusted by increasing or decreasing the number of the modules according to construction requirements, and the dragging tool adapts 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. ...
