[0002] During the salvage operation of a sunken ship, the sunken ship may be tilted or inverted. The sunken ship must be straightened to a normal state before restoring its internal buoyancy or salvaging it as a whole. At the same time, considering the limited strength of underwater welding, the straightening tooling must be non-welded. In the past, non-welded straightening fixtures usually had the following three defects: first, the fixture structure is a right-angle fixed type, and the deck surface of the ship usually has a certain arch in the direction of the ship width, and the size of the curvature varies with the ship type. The conventional right-angle fixed structure cannot fit the deck surface and the side of the sunken ship well, and thus the straightening fixture cannot maximize its straightening effect; second, the fixture structure adopts a cylindrical lifting lug to connect the straightening wire rope, and the straightening wire rope cannot be connected in advance on the water. The fixture must be placed in place first, and then the diver connects the lifting lug and the wire rope underwater, which increases the underwater work volume and difficulty, and cannot effectively release the torque of the straightening wire rope; third, the fixture structure is a solid structure, and its underwater weight is large, which is not conducive to the diver to cooperate with the crane underwater to fine-tune the placement of the fixture.
