Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for lifting operations, in particular to an automatic retractable and unhooking hook for boats. Background Art

[0002] The lifting operation at sea is to use the launching and retracting mechanism to lower the small boat from the mother ship to the sea surface, and then release the unhooking device to make the small boat detach from the connection of the launching and retracting mechanism, or fasten the small boat on the sea surface through the unhooking device and then retract it to the mother ship. Since the launching and retracting process needs to be completed under the disturbance of waves, there are high requirements for the safety performance of the unhooking device and its working stability under severe weather conditions.

[0003] However, since the retracting and releasing device cannot automatically retract the rope, it is often necessary to manually remove the rope, and the rope is hung in the hook, and due to gravity, it is difficult to remove the rope from the hook.
