Tool for quickly loosening reserved rope and anchor chain

Abstract

The invention discloses a tool for quickly loosening a reserved rope and an anchor chain. The tool comprises a base structure fixed to the deck surface of a ship, a hook loosening bottom plate is fixedly arranged on the base structure, a hook provided with the reserved rope or the anchor chain is hinged to the hook loosening bottom plate, a clamping plate used for clamping the hook is further hinged to the hook loosening bottom plate, and the hinge points of the hook and the clamping plate on the hook loosening bottom plate are spaced; and a safety auxiliary groove used for sharing stress is formed in the surface of the hook, or a safety auxiliary hole used for sharing stress is formed in the hook, a steel wire rope used for sharing stress is fixedly arranged on the base structure, one endof the steel wire rope is fixedly connected to the base structure, and the other end of the steel wire rope is connected to the base structure in a fastening or clamping mode. The supporting point oftension is changed, shackles do not need to be disassembled, through mechanical calculation, the mechanical steering working principle and the lever principle, the acting point of force is transferred, the force is reduced, operation is convenient, the hook loosening speed is increased, and the cross arm recycling operation waiting time is shortened.

Description

technical field [0001] The invention relates to a tool for quickly releasing hooks for retaining ropes and anchor chains. Background technique [0002] When the ship is launched, the deck surface needs to be welded to hold the fixing device of the steel wire rope or anchor chain, and the other end of the rope is fixed on the slide cross arm and other devices under the ship. After the ship is launched, the fixed point on the deck needs to loosen the rope in time so that The current design of the water recovery cross arm operation is that the lifting lug device is welded on the deck surface to pull the wire rope. After launching, because the lower end of the wire rope is a launching cross arm (heavy), the rope has a strong effect, and the wire rope shackle cannot be disassembled. , the lifting lugs can only be cut off on the deck, and the lifting lugs are easy to fly and hurt people at the moment of cutting due to the force. [0003] Therefore if can design a firmly fixed, ne...

[0002] When the ship is launched, the deck surface needs to be welded to pull the fixing device of the wire rope or anchor chain, and the other end of the rope is fixed on the slide cross arm and other devices under the ship. After the ship is launched, the fixed point on the deck needs to loosen the rope in time, so that The current design of the water recovery cross arm operation is that the lifting lug device is welded on the deck surface to pull the wire rope. After launching, because the lower end of the wire rope is a launching cross arm (heavy), the rope has a strong effect, and the wire rope shackle cannot be disassembled. , the lifting lugs can only be cut off on the deck, and due to the force of the lifting lugs, it is easy to fly and hurt people at the moment of cutting, which is laborious, time-consuming and has potential safety hazards, and prolongs the underwater recovery cross-arm operation
