Special sling for submersible

Abstract

The invention relates to a placing and recycling device of a submersible device, and particularly relates to a special lifting appliance for a submersible device. The special lifting appliance for the submersible device comprises lifting locks, lifting strips, a lifting cross beam and steel wire ropes, wherein the lifting cross beam is of a rectangular structure, and the upper parts of four corners of the lifting cross beam are respectively connected with one end of each steel wire rope, and the other ends of the four steel wire ropes are connected with one another; round rings are respectively arranged below four corners of the lifting cross beam; each round ring is connected with one end of one lifting strip; the other end of the lifting strip is connected with the lifting locks; each lifting lock is connected with the submersible device detachably; the submersible device is released or lifted up by the lifting locks. The placing and recycling device of the submersible device, which is provided by the invention, is simple and reasonable in structure design, is convenient to use, and is safe and reliable.

Description

technical field [0001] The invention relates to a device for deploying and recovering a submersible, in particular to a special sling for a submersible. Background technique [0002] Hoisting, deployment and recovery are repetitive operations that frequently occur during the use of submersibles. During this process, the safety and reliability of hoisting must be guaranteed, that is, to ensure the safety of personnel, and to avoid collisions with submersibles. Put an end to all potential safety hazards, and at the same time improve the convenience of operation. [0003] In the traditional design of submersible slings, the commonly used lifting methods include sling hoisting, hook hoisting and special slings. Among them, the sling hoisting style does not require the submersible to design a special hoisting structure, which can ensure the appearance of the submersible and ensure a streamlined shape, but the hoisting position and the sling hoisting position and method are not c...

AI Technical Summary

Problems solved by technology

Among them, the sling hoisting style does not require the submersible to design a special hoisting structure, which can ensure the appearance of the submersible and ensure a streamlined shape, but the hoisting position and the sling hoisting position and method are not clear, and there are differences in the hoisting methods of different operators. It is easy to cause slippage and other hanging hazards due to inaccurate estimation of the center of gravity position; the hook lifting method needs to install auxiliary structures such as hooks, rings or wire ropes on the submersible, which is easy to form auxiliary structures, which is not conducive to the operation of the submersible. When deploying and recovering the submersible, it is difficult to unhook and hook, especially in harsh sea conditions, the operability is very poor
