Abstract

The invention discloses a wind generation set impeller assembling device which is characterized by comprising an installation seat (1) used for positioning and supporting a hub (5), and multiple impeller installing devices used for installing an impeller (6) and the hub (5) in an aligned mode. The impeller installing devices are respectively connected with the installation seat (1) so as to form an impeller assembling platform. The installation seat (1) is provided with a plurality of connection portions (10) which are connected with the impeller installing devices respectively. When the impeller is assembled, the hub (5) is arranged on the installation seat (1), each variable pitch bearing of the hub (5) corresponds to one impeller installing device, the impeller (6) is placed on one corresponding impeller installing device and moved to one corresponding variable pitch bearing of the hub (5), so that the impeller and the hub are connected. According to the wind generation set impeller assembling device, the impeller and the hub can be fast aligned and positioned, installing the impeller is fast, the structural design is simple, and the wind generation set impeller assembling device is convenient to use and applicable.

Description

technical field [0001] The invention relates to the field of wind turbine impeller assembly, in particular to a device and an assembly method for wind turbine impeller assembly. Background technique [0002] Due to the long blade length of the wind turbine, the assembly size of the impeller is relatively large, which has high requirements for the installation site. The traditional method of assembling the impeller is: two cranes are used to cooperate, and the blade and the hub are assembled by lifting the blade and the hub several times by using a suitable spreader. However, the positioning of the blade and the hub is difficult and time-consuming. In addition, after the blade and the hub are aligned, the backing plate installed at the end of the blade will affect the pitch of the blade, the blade is easy to break, and the blade and hub assembly is in danger of overturning. Contents of the invention [0003] The purpose of the present invention is to overcome the above-men...
