[0002] The marine rope storage winch is an important device on a ship, used to store the mooring cable when it is not in use. As the tonnage of the ship increases, the diameter of the mooring cable used is also getting larger and larger. However, traditional rope storage winches often lack an effective rope arranging device, resulting in the need for 3 - 5 people to assist in manual rope arranging during the rope winding process. This not only increases the labor intensity of the crew but also poses certain inconveniences and risks during operation.

[0003] In addition, the rope arranging devices of some rope storage winches are designed similar to those of hoisting winches. However, since the external load is relatively small during the cable winding process of the rope storage winch, the cable is often in a slack state, which also requires manual assistance and cannot fully achieve automation. These problems not only increase the labor intensity of the crew but also affect the operation efficiency of the ship. Summary of the Utility Model

[0004] Aiming at the above problems, the main purpose of the utility model is to design a rope arranging and pressing device for a cable storage winch, which solves the problem of manual assistance required for rope arranging during the rope winding process of the winch through the cooperation between a bidirectional lead screw, a guide shaft, and a rope arranging guide frame installed on the bidirectional lead screw and the guide shaft.
