Automatic releasing lifting hook structure and using method thereof

Abstract

The invention discloses an automatic releasing lifting hook structure and using method thereof for lifting and realizing of an underwater or water surface navigation device. The automatic releasing lifting hook structure includes a right hook claw, a first rotating shaft, a first torsion spring, a first left hook claw, a second rotating shaft, a second torsion spring, a second left hook claw, a baffle, a third rotating shaft and a third torsion spring. By using the self-locking function of a tooth structure between the left hook claw and the right hook claw, so that when a lifting hook is notforced, the lifting hook is closed and self-locked; when the hook is pulled downwards, the baffle loses the limiting function for the left hook claw; and when the lifting hook is not forced again, thelifting hook is automatically opened, the lifting hook is separated automatically after the underwater or water surface navigation device enters water. The automatic releasing lifting hook structurehas the advantages that after the underwater or water surface navigation device is lifted and enters the water, the lifting hook is separated from a lifting point automatically, and the purpose that the navigation device is released automatically is achieved; and divers do not need to carry on operation in water, manpower and physical consumption is reduced, and the lifting and releasing efficiency of the navigation device is improved.

Description

technical field [0001] The invention belongs to the technical field of underwater or surface mechanical devices, and relates to a hook for lifting an underwater or surface vehicle, in particular to an automatic release hook structure for lifting and releasing an underwater or surface vehicle and a method for using the same. Background technique [0002] The most common method for releasing underwater surface vehicles is to use hoisting equipment arranged on the hull and wharf to lift the underwater surface vehicle and realize entry into the water. This method is relatively low in cost, and the entry direction and position of the underwater surface vehicle are relatively easy. manipulation. [0003] After the underwater surface vehicle enters the water, the hook needs to be separated from the lifting point of the underwater surface vehicle, so as to realize the release of the underwater surface vehicle. Before the present invention, the release operation of the underwater su...

Problems solved by technology

The disadvantage of this method is: when the environment in the lifting area is relatively harsh, such as poor sea conditions, night work, etc., the difficulty and risk of divers' underwater operations are relatively large, and this method requires additional manpower, material resources, and low efficiency.
