Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable winch, in particular to a cable winch with slack rope protection structure. BACKGROUND

[0002] When the ship is docked at the wharf, the ship's own generator is no longer used, and the power supply is realized by connecting with the power supply of the wharf through the cable; when the ship leaves the shore, the cable is wound to avoid the movement of the cable; in this process, the winding and unwinding of the cable are realized through the cable winch.

[0003] For example, Chinese patent CN114476866A discloses a shore power cable winch, which is driven to rotate by a driving structure to wind up, and when the unwinding speed of the winding drum is greater than a preset value, a limiting structure limits the unwinding rotation of the winding drum to avoid the loosening and knotting of the cable caused by the unwinding speed of the winding drum.

[0004] However, when the cable is in use, if it is too tight, it is easy to break; if it is too loose, the cable is easy to rub against other objects, thereby accelerating the wear; and when unwinding, the unwound cable is easy to pull the cable on the winch, thereby causing the cable on the winch to be subjected to a large continuous pulling force; at the same time, when winding, it is difficult to ensure that the cable is tightly and evenly arranged without being too tight.

[0058] At the same time, when the cable is loosened, the linear module two 532 drives the arc-shaped support frame 533 and the guide roller 534 to move rightward and upward, thereby driving the cable to expand outward while lifting, so that the cable is no longer loosened; if the cable is tight, the linear module two 532 drives the arc-shaped support frame 533 and the guide roller 534 to move leftward and downward, thereby driving the cable to converge inward while moving downward, so that the cable is no longer tight; thereby realizing the adjustment of the tightness of the cable.
