Multifunctional hoisting winch for use manned submersible recovery operation

Abstract

The invention discloses a multifunctional hoisting winch for use manned submersible recovery operation. The multifunctional hoisting winch comprises a hoisting winch assembly, a speed reducer, a hydraulic motor and a hydraulic control system, wherein the hydraulic motor is connected to a first pipeline and a second pipeline of the hydraulic control system; the hydraulic control system comprises awinch control valve bank and an energy accumulator valve bank; the winch control valve bank comprises an electromagnetic valve, a balance valve and a proportional overflow valve; the output end of theelectromagnetic valve is connected to the first pipeline and the second pipeline respectively; the input end of the electromagnetic valve is connected to a pressure oil pipeline and an oil return pipeline respectively; the balance valve is connected in series to the second pipeline; a pilot control valve of the balance valve is connected to the first pipeline; the proportional overflow valve is connected in parallel between the first pipeline and the second pipeline; the energy accumulator valve bank comprises a reducing valve, a sequence valve and two energy accumulators which are arranged in parallel; and the energy accumulator valve bank is used for supplementing oil to the first pipeline and the second pipeline. Through the technical scheme of the invention, constant-tension pre-tightening of a cable in the hoisting winch is realized, and the influence of impact generated when a submersible gets out of the sea surface is reduced.

Description

technical field [0001] The present application relates to the technical field of diving equipment, in particular, to a multifunctional hoisting winch used for recovery operations of manned submersibles. Background technique [0002] Deep-sea science is one of the important directions of the frontier of science, and deep-sea scientific research relies on technical means and equipment support. As a particularly important deep-diving operation equipment, manned submersibles can be used to perform tasks such as underwater surveys, geological exploration, sample collection, pipeline maintenance, and salvage and lifesaving. When the manned submersible is operating, a special hoisting system is required to use the lifting winch 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 harsh sea conditions. The comprehens...

Problems solved by technology

[0004] In the prior art, the hoisting winch function of the hoisting system of the manned submersible is often relatively simple, and the operation adaptability in complex sea conditions is not ideal

In particular, when the hydraulic motor of the winch fails, the system does not have the emergency recovery operation capability of the submersible, which seriously affects the safety of the submersible and the submersible equipment.
