Description

Technical Field

[0001] This utility model relates to the field of marine operation technology, and in particular to a compensating conveying device for marine operation platforms. Background Technology

[0002] With the rapid development of marine new energy development, offshore operation platforms are being used more and more widely in the field of marine engineering technology, especially in wind power generation and offshore exploration. Taking wind power generation as an example, the installation and maintenance of offshore wind turbines require efficient and reliable transportation equipment to ensure the stable and accurate transport of maintenance personnel or equipment and materials to be installed on offshore operation platforms.

[0003] Most existing offshore platforms use traditional lifting equipment as transport devices. During transport, due to the high center of gravity of the lifting equipment, it is easily affected by wind resistance, causing the lifting equipment to shift or tilt, increasing the difficulty and risk of lifting operations. Furthermore, it is difficult to predict the operating window, limiting the planning and continuity of operations. To alleviate the difficulty and risk of high-altitude lifting and transport, wind resistance compensation devices or systems need to be introduced to improve operational stability and safety, but this increases the structural complexity of the lifting equipment and the investment cost.

[0004] To address the issues of high center of gravity and poor stability in the aforementioned lifting equipment, existing technologies have developed conveying methods that lower the center of gravity. However, existing conveying devices generally employ a platform and roller movement method, using a movable platform to transport or transfer maintenance personnel or equipment and materials to be installed. However, the existing mobile conveying devices have poor structural design and are prone to roller jamming, which affects the stability of the conveying process and requires further improvement.

[0005] Therefore, further research and development is needed to solve the problems existing in the above-mentioned technologies. Utility Model Content
