Problems solved by technology
In the process of connecting the anchor cable and the anchor chain, the anchor cable is in a catenary state in the water, and its posture is swaying, which brings difficulties to the operation of connecting the anchor cable and the anchor chain. At the same time, there are potential safety hazards, which are easy to damage the anchor cable joint
Shark clamps cannot be used to clamp the anchor cable directly to temporarily fix the anchor cable, because the shark clamp will damage the anchor cable

Embodiment Construction
[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0021] Figure 1 to Figure 2 It shows an anchor cable joint limit protector in the present invention, the anchor cable joint limit protector is mainly aimed at the instability of the catenary posture of the anchor cable, which makes it difficult to connect the anchor cable and the anchor chain on the deck of the dynamic positioning ship , and the design of the situation where there is a safety hazard of damage to the anchor cable joint. When in use, fix the limit protector of the anchor cable joint at the position of the shark jaw. When connecting the anchor cable and the anchor chain, place the anchor cable joint in the limit protector to ensure the stability of the catenary posture of the anchor cable and ensure the s...

The invention discloses a limiting protector for an anchor cable rope joint. The limiting protector for the anchor cable rope joint comprises a protector body; the front convex part of the protector body is in a wedge shape, so that the protector body abuts against a pair of shark pincers; the front portion of the protector body is provided with a first opening used for installation of an anchor cable in an operable mode; the rear portion of the protector body is provided with a second opening used for clamping the anchor cable rope joint in an operable mode. According to the technical scheme, the protector body of the limiting protector for the anchor cable rope joint can be clamped on the shark pincers, the anchor cable rope joint is fixed through the second opening in the protector body, and therefore the braced chain gesture of the anchor cable is stable. Smooth connection between the anchor cable and an anchor chain is guaranteed, and potential safety hazards of damage to the anchor cable rope joint are avoided.
Description
technical field [0001] The invention relates to the field of marine engineering, in particular to a limit protector for anchor cable joints. Background technique [0002] In the project of installing single point mooring system in the South China Sea, a dynamic positioning vessel is used to lay anchor cables. The way to lay the anchor chain is to export it through the winch on the dynamic positioning ship, and then import it into the water through the stern drum, and lay it on the designed route. At the same time, the dynamic positioning ship moves forward along the designed route, continues to lead out the anchor cable, and lays it on the designed route. [0003] After finishing laying the anchor cable, continue to connect the anchor cable and the anchor chain on the deck of the dynamic positioning ship, and lay the anchor chain. In the process of connecting the anchor cable and the anchor chain, the anchor cable is in a catenary state in the water, and its posture is swa...
