A serial type marine lifting compensation device

Abstract

The invention belongs to the field of marine deck machine related equipment and discloses a series type marine lifting compensation device. The device comprises a main base, a movable gallery ladder,an intermediate gallery ladder and a connecting gallery ladder. Meanwhile, the movable gallery ladder is provided with a translational motion joint module. Each of the intermediate gallery ladder andthe connecting gallery ladder is provided with a rotating joint module. When a ship fluctuates due to waves and longitudinally inclines, under the horizontal movement effect of the movable gallery ladder and the circular rotation effect of the intermediate gallery ladder, the connecting gallery ladder can be kept horizontally, and meanwhile, the absolute height and the horizontal position of the connecting gallery ladder are not changed. By the adoption of the device, a multi-joint structure series robot mode can be fully used for counteracting and eliminating various swing and oscillation motions, compared with existing equipment, the device better guarantees high-accuracy lifting compensation of a wind power maintenance ship and other marine operation ships, and meanwhile the device hasthe beneficial effects of being high in compensation rate, adaptability, stability and the like.

Description

technical field [0001] The invention belongs to the field of equipment related to marine deck machinery, and more specifically relates to a series-type marine lifting compensation device. Background technique [0002] The current wind power generation is second only to hydropower, and has accounted for 16% of the world's electricity generation from renewable resources. In the context of the global focus on the development of a low-carbon economy, offshore wind power has become one of the important sources of renewable energy power. In densely populated coastal areas, gigawatt-scale offshore wind farms can be quickly established, which also makes offshore wind power one of the most important technologies to reduce carbon emissions in energy production in a cost-effective manner. Although offshore wind power started relatively late, relying on the stability of sea wind resources and the characteristics of large power generation, offshore wind power has been developing rapidly...

AI Technical Summary

Problems solved by technology

However, further studies have shown that the above-mentioned existing equipment still has the following defects or deficiencies: First, this type of heave compensation device is mostly used in offshore hoisting operations or lifting operations. There are still no good solutions for the heave compensation of fixed structures. Secondly, the existing equipment still has problems such as high power consumption, low compensation accuracy, and insufficient stability of compensation performance.
