Problems solved by technology

The conventional practice is to build a test platform in a land laboratory, and test a single set of hydraulic lifting cylinders and buffers separately. It is impossible to test the entire lifting system composed of multiple sets of hydraulic buffer synchronous lifting devices, ship motion and marine environmental conditions in actual engineering. Realistic and effective simulation of the system

Embodiment Construction

[0021] like image 3 As shown, the shipwreck simulator 11 is a steel salvage buoy, which is filled with concrete or iron sand for counterweight, with a lifting eye plate 16 arranged on the top, and a towing eye plate 17 arranged at both ends. The lifting eye plate 16 is used for hoisting and towing. Eye plate 17 is used for dragging and moving. The shipwreck simulator 11 is normally in a floating state and can be wet towed by a tugboat, and can be used as a shipwreck simulator by ballasting and sinking.

[0022] The synchronous hoisting system is connected with the wire rope 10 by dragging the anchor head 18, and the wire rope 10 passes through the guide roller 8 and is connected with the shipwreck simulator 11. Then use the hydraulic buffer synchronous lifting system to lower and lift it, and test and verify the performance of the hydraulic buffer synchronous lifting system.

[0023] The test steps are as follows:

[0024] The offshore test platform is mainly composed of a...

Abstract

The invention discloses a large-tonnage sunken ship salvage hydraulic buffering synchronous lifting system offshore test platform, which belongs to the technical field of salvage, and comprises a barge, a plurality of groups of synchronous lifting devices, a sunken ship simulator and a monitoring system, the synchronous lifting device is connected with the shipwreck simulator through a steel wire rope. According to the offshore test platform of the large-tonnage sunken ship salvage hydraulic buffering synchronous lifting system, the offshore test platform is provided, reasonable simplification treatment is carried out by adopting a sunken ship overall salvage scheme of the hydraulic buffering synchronous lifting system, and an offshore simulation test of sunken ship overall salvage is carried out; key performance indexes such as rated load, lifting and descending speed, buffer compensation performance and synchronization precision of the whole hydraulic buffer synchronous lifting system are tested and verified more systematically and accurately, and a more accurate and reliable technical basis is provided for scheme design of formal salvage engineering.

Description

technical field [0001] The invention relates to the technical field of salvage, in particular to an offshore test platform of a hydraulic buffer synchronous lifting system for salvage of large tonnage sunken ships. Background technique [0002] Aiming at the overall deep-water salvage operation of large-tonnage sunken ships, it breaks through the shortcomings and limitations of traditional technology in terms of its own application functions such as small tonnage, inconvenient operation, heavy workload, and easy to be affected by external environmental factors. The overall sunken ship salvage technology combined with the lifting system is more and more widely used. Among them, the hydraulic buffer synchronous lifting system is the key equipment in the overall salvage process of large tonnage sunken ships. It is generally composed of hydraulic steel strand hoist, buffer compensator and central control system, and has the functions of hydraulic synchronous lifting, heave buffe...
