Description

[0002] With the increasing global demand for renewable energy, the development and utilization of wind energy as a clean and renewable energy form has received widespread attention. As one of the main ways to utilize wind energy, wind power generation technology continues to mature and installed capacity continues to grow. During the installation and maintenance of wind turbines, especially for the installation of key components such as shaft cabinets, due to the relatively high height of the main column of the wind turbine, when the shaft cabinet needs to be installed at the corresponding height, it is difficult to achieve it by manual transportation. At this time, lifting equipment is usually used for lifting operations.

[0003] Due to the limitations of wind turbine sites, especially mountainous slopes, conventional cranes cannot be moved to the installation site. Portable lifting devices are often used for lifting operations. However, once most lifting devices are mounted on the frame, their angles are limited, and neither the angle nor the suspension position can be adjusted. This inability to adjust the angle makes it difficult to adjust the orientation of the shaft cabinet. In view of this, we have proposed an adjustable lifting device for installing the wind turbine shaft cabinet. Utility Model Content
