Description

Technical Field

[0001] The utility model belongs to the technical field of cable retracting and releasing, and in particular relates to a cable retracting and releasing device for docking ships. Background Art

[0002] Cables are tools used to secure ships, ensuring safe and stable docking. They are essential infrastructure for preventing ship drift and crucial for ensuring safe and stable docking. In severe weather or sea conditions, the stability of cables is directly related to the safety of the ship and crew. Cables require a retractable device for retracting and releasing cables. Existing cable retractable devices use a reel with a fixed width, making them inflexible and unsuitable for reeling in longer cables. Furthermore, the retractable device can become loose when pulled by the cable, resulting in instability and certain drawbacks.

[0003] For example, the technical solution with application number "2019217990543" and patent name "A marine cable retracting and releasing device" uses a gear set consisting of two gears for power transmission. On the one hand, this method will lose some power. At the same time, during the rotation of the second shaft, due to the gravity of the cable, it may cause imbalance during the rotation of the second shaft; at the same time, this technical solution uses a laser receiver and a transmitter to identify the degree of cable release, but the disadvantage of this method is that after the first release is completed, if the cable is recovered, it does not need to be completely recovered at this time. It is possible that the cable stored on the roller at this time cannot completely block the laser receiver. Then, when the cable is released again, the degree of cable release cannot be identified by the laser receiver and the transmitter. That is, this method is only applicable to the complete release and storage of fixed cables, and cannot cope with the actual cable needs to cope with a variety of ships and a variety of storage and release situations. At the same time, when the tonnage of the ships differs greatly, the required cable thickness is also different. The cable in the above technical solution uses two pulleys to ensure that the cable is evenly wound on the roller when stored. However, for cables of different sizes, since the distance between the two pulleys is fixed, it is not applicable. Summary of the Invention

[0004] The purpose of the present utility model is to provide a cable retracting and releasing device for ship docking in order to solve the above-mentioned problems. The device has the advantages of being able to retract and release cables of longer lengths to meet the needs of different situations. At the same time, it can gather the reeled cables inward to avoid the cables being scattered. At the same time, it can buffer the dragging force of the cables to avoid damage to the extendable and gathering retracting and releasing part and the retracting and releasing motor.
