Description

Technical Field

[0002] With the rapid development of renewable energy, wind power generation, as a clean energy, has received more and more attention. The installation and maintenance of wind turbines are key links to ensure their efficient operation. However, there are some technical difficulties and shortcomings in the actual operation of the wind turbine tower crane installation: 1) The mixed tower structure of a wind turbine generator set is usually composed of multiple large segments, and the hoisting and positioning of these segments require extremely high precision and stability. Traditional hoisting methods often rely on manual operation and simple hoisting equipment, which makes it easy for errors to occur during the hoisting process, and in serious cases may even cause equipment damage or safety accidents; 2) Existing lifting equipment lacks flexibility and adaptability. Since wind turbines of different models and specifications may use segments of different sizes and shapes, existing equipment is difficult to quickly adapt to different lifting tasks, increasing the complexity and time cost of construction; 3) Safety is always an important consideration in hoisting operations. The safety locking mechanism of traditional equipment is often not reliable enough, and there may be a risk of pipe segments slipping during the hoisting process, posing a potential threat to construction personnel and equipment.
