Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blade installation, in particular to a flip device for wind turbine blade installation. Background Art

[0002] As an indispensable component of wind power generation, wind turbine blades are directly related to the conversion efficiency of wind energy. The larger the wind turbine blades are, the higher the wind energy conversion efficiency is. At present, wind turbine blades are usually hollow and integrated. Since wind turbine blades are long, they are usually transported horizontally during transportation. However, after being transported to the installation location, they usually need to be rotated. At this time, since wind turbine blades are irregular objects and are long, they will be damaged due to the eccentric center of gravity when they are rotated. Therefore, there is a certain risk.

[0003] The publication number CN 113829269 A discloses a flipping device for installing a wind turbine blade, comprising a base, a rotating wheel and a plurality of fixing mechanisms, wherein the base is slidably connected to the rotating wheel, the fixing mechanism is used to fix the wind turbine blade, and the fixing mechanism is connected to the inner side of the rotating wheel through a damper;

[0004] When in use, the fixing mechanism is installed through two bases, so that after the wind turbine blade is clamped, the bases on both sides move in different directions or offset, and the device needs to be manually rotated by personnel, which is time-consuming and laborious for the staff; therefore, we propose a flipping device for wind turbine blade installation.
