Impeller assembling device and impeller assembling method

Abstract

The invention provides an impeller assembling device and an impeller assembling method. The impeller assembling device comprises a supporting base and a plurality of supporting legs, wherein a connecting end surface capable of supporting a hub of an impeller and a fixed end surface which is parallel to the connecting end surface and can be supported on an external supporting platform are arranged on the supporting base; a part between the connecting end surface and the fixed end surface extends to form a wall; each supporting leg comprises a first end and a second end; each first end is connected with the wall of the supporting base; each second end extends to the direction which is away from the supporting base and is supported on the external supporting platform; and each two adjacent supporting legs are separated from each other at a preset angle. Overturning of blades in an assembling process can be prevented, and meanwhile, the site area of a wind turbine is reduced.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to an impeller assembly device and an impeller assembly method. Background technique [0002] With the rapid development of wind power technology, wind farms have gradually expanded from the eastern coastal areas to various regions. For example, there are more and more projects in the southern mountainous areas. However, considering the construction cost of wind farms, the operating area of ​​wind farms is generally smaller small. [0003] When building a wind farm, it is necessary to assemble the hub and three blades of the wind turbine on the ground first, and then hoist it to the top of the tower as a whole to connect with the generator. The length of the blade is more than ten meters. When one blade is assembled with the hub, in order to prevent the deformation of the blade caused by the blade mopping the ground, it is necessary to use a lifting mechanism to hold ...

AI Technical Summary

Problems solved by technology

However, the hoisting mechanism needs a certain footprint when performing hoisting operations, and the boom of the hoisting mechanism also needs a certain radius of gyration.

[0004] However, when assembling impellers with small operating areas such as mountains and forests, due to the narrow construction site, the auxiliary crane cannot stand, which makes it difficult to assemble the impellers

Moreover, it is easy to be unbalanced when assembling the impeller, which will cause the wind power equipment to overturn or even be damaged.
