A lifting winch for emergency recovery operation of manned submersible

Abstract

This application discloses a hoisting winch for emergency recovery operations of manned submersibles, which includes a hoisting winch assembly and a hydraulic motor. The hoisting winch assembly includes: an annular boss is arranged on the drum, and a second A bearing cover plate, a blind hole is arranged above the first bearing cover plate; multiple thin-walled bearings are arranged side by side, the bearing inner ring of the thin-walled bearing is installed above the annular boss, and the bearing outer ring of the thin-walled bearing is installed on the pulley Below, the connection between the inner ring of the thin-walled bearing and the annular boss is a single-side shoulder positioning method; the left side of the pulley is provided with a threaded long hole, and a set screw pin is installed in the threaded long hole. After the fixed screw pin is screwed out of the blind hole, the pulley can rotate on the reel; the second bearing cover plate is installed on the right side of the pulley to limit the thin-walled bearing. Through the technical solution in this application, the pulleys used for emergency recovery are integrated on the reel of the existing hoisting winch, so as to improve the safety and efficiency of emergency recovery of the submersible.

Description

technical field [0001] The present application relates to the technical field of diving equipment, in particular, to a hoisting winch used for emergency recovery operations of manned submersibles. Background technique [0002] Deep-sea science is one of the important directions in the frontier of science, and deep-sea scientific research relies on technical means and equipment support. As a particularly important deep diving equipment, manned submersibles require a special hoisting system to deploy the submersible from the deck to the water surface or recover it from the water surface to the deck of the mother ship. [0003] Due to the large weight and shape of the manned submersible, it often operates in severe sea conditions. The combined effects of wind, waves and currents during the recovery process cause the submersible and the working mother ship to have a relatively large relative movement. Cables tend to have large shock loads, leading to the possibility of failure ...

AI Technical Summary

Problems solved by technology

[0003] Due to the large weight and shape of the manned submersible, it often operates in harsh sea conditions. The comprehensive influence of wind, waves and currents during the recovery process makes the submersible and the working mother ship have relatively large relative movements. At this time, the submersible is in the process of leaving the sea surface Cables tend to be subject to high shock loads, leading to the possibility of failure of the hoisting winch

In addition, problems such as system power failure, oil leakage, and component failures may occur during the operation. At this time, emergency recovery of the manned submersible must be implemented

[0004] In the prior art, in order to carry out emergency recovery to the manned submersible when the hoisting winch breaks down, a set of emergency recovery device is usually provided separately. limited space; when in use, temporary assembly is required, which not only reduces the emergency recovery efficiency of the manned submersible, but also causes a waste of existing resources
