Problems solved by technology
However, due to the long lifting distance and the working environment of the wind turbine, the existing lifting device of the wind turbine is limited by the wind speed condition. In general, the lifting of materials is prohibited
At the same time, even in the case of low wind speed, friction or collision between the suspended lifting materials and the tower, high-voltage cables or other high-altitude devices is prone to occur, resulting in damage to the tower and materials or triggering high-voltage electric shocks and other losses or Safety accidents, unable to meet the lifting needs of wind turbines

The invention relates to a lifting device, a lifting system and a wind power generating set. The lifting device is used for a nacelle of a wind power generating set, and comprises: a lifting part connected to the nacelle for lifting materials along a first direction; a guiding part , connected to the nacelle, the guiding part includes two or more guiding parts arranged at intervals, the two or more guiding parts are distributed around the lifting part and extend along the first direction; the connecting part includes a fixed part and a moving part connected to each other, and the connecting part The fixed part is fixedly connected with the lifting part, and is slidably connected with the guide part through the moving part. The object-hanging device, the object-hanging system, and the wind power generator set provided by the embodiments of the present invention can meet the material lifting requirements under different wind conditions, and at the same time can ensure the safety of material lifting.
Description
technical field [0001] The invention relates to the technical field of wind power, in particular to an object-hanging device, an object-hanging system and a wind power generating set. Background technique [0002] As a clean and renewable energy, wind energy has attracted more and more attention from all over the world. The wind power industry has also developed rapidly, and wind power generators have been widely used for this reason. The installation and maintenance of wind turbines usually involves the lifting of materials, such as lifting materials on the ground to the nacelle, or hoisting materials in the nacelle to the ground, etc., to ensure the safety and stability of wind turbines. run. [0003] In the prior art, a spreader is generally installed at the lifting hole in the wind power generating set for lifting materials to the nacelle or from the nacelle to the ground. However, due to the long lifting distance and the working environment of the wind turbine, the ex...
