Abstract

The invention discloses an experimental platform of the passive heave compensation for the simultaneous lifting of a shipwreck, and belongs to the field of platform experiments. The experimental platform mainly comprises a driving device assembly, a ship platform simulation assembly, a compensation platform assembly, a loading assembly, a counterweight assembly, a frame body, a steel wire rope, fixed pulleys, a movable pulley, a fixed pulley block, and the like. The steel wire rope is connected to a guide shaft through a Hough, and the travel is amplified through the pulley block. The ship simulation platform is arranged on a guide rail, so that the stability of the deep sink motion is guaranteed. Guide rods are arranged between the ship simulation platform and the compensation platform, so that the parallel motion between the ship simulation platform and the compensation platform is ensured. And the platform uses a bidirectional hydraulic motor to drive the drum as a load, and adjuststhe output load by adjusting the working pressure of the bidirectional hydraulic motor. According to the experimental platform of the passive heave compensation for the simultaneous lifting of the shipwreck, the experiment platform has the advantages that the platform is stable and reliable in the operation, has large amplitude in the heave motion, is flexible in the experiment loading, and the like.

Description

technical field [0001] The invention relates to a heave compensation experiment platform, in particular to a passive heave compensation experiment platform used for simultaneous lifting of sunken ships. Background technique [0002] With the increasing frequency of human marine activities, there are more and more ships of all kinds on the sea, and the probability of ship accidents also increases. Once a ship sinks in distress, it will not only cause serious property losses, but also seriously affect the normal shipping safety, so it is necessary to actively rescue and salvage the sunken ship. [0003] Steel strand hydraulic synchronous lifting technology is the most emerging salvage technology. Because of its strong adaptability, easy control, small size and high efficiency, it has been more and more widely used in the field of sunken ship salvage. Under the action of the heave movement of ocean waves, there will be uneven stress on the steel strands during the salvage proc...
