Vertical type salvage system with double barges and lifting steel strands for hydraulically-synchronous lifting sunken vessel

Abstract

The invention provides a vertical type salvage system with double barges and lifting steel strands for hydraulically-synchronous lifting a sunken vessel. The vertical type salvage system with the double barges and the lifting steel strands for hydraulically-synchronous lifting the sunken vessel comprises pulling jack mechanisms, the steel strands, connectors, steel wire ropes, steel strand guidingdevices, winches, hydraulic pump stations and control systems, wherein the pulling jack mechanisms, are fixedly connected to the sides of the barges; and after penetrating through the pulling jack mechanisms, one ends of the steel strands are connected with the winches through the steel strand guiding devices, and the other ends of the steel strands are connected with the steel wire ropes throughconnectors. According to the vertical type salvage system with the double barges and the lifting steel strands for hydraulically-synchronous lifting the sunken vessel provided by the invention, the pulling jack mechanisms are perpendicularly placed on the sides of the barges, so that the width limitation of barge decks is broken through; and the length of each steel strand can be decided throughthe depth of the corresponding barge, so that the deep-water sunken vessel can be salvaged.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a vertical double-barge prying steel strand hydraulic synchronous lifting salvage system for sunken ships. Background technique [0002] Rescue and salvage is an important part of the national emergency support system. It undertakes multiple tasks such as rescue of life, property, environment at sea, salvage of sunken ships and sunken objects, and other safety guarantees for maritime transportation and marine resource development. Among them, salvage of sunken ships is due to the tonnage of The particularity of large size, large volume, and complex surrounding sea conditions is an important part of reflecting the country's maritime strength. [0003] The salvage plan used at that time was to use pulling jacks to lift the sinking ship, place two large barges on each side of the "smooth" stern section, and use 7 jack holes that had passed through the shipwreck to thread ...

AI Technical Summary

Problems solved by technology

The traditional salvage scheme is to arrange the hoisting mechanism horizontally on the barge deck, which requires the hoisting rope or line to be bent at an angle of about 90 degrees on the side of the barge, which can be done by steel wire rope, but not by steel strand. Yes, so the above scheme places the connector above the barge deck, so that the lifting height of the tension jack depends on the length of the steel strand in front of the connector, and the length of the further steel strand is limited by the width of the barge deck, so When encountering deep sea salvage, the width of the barge deck required by this type of solution is likely to exceed the existing barge, making salvage impossible
