The invention discloses a wind driven generator and a method for hoisting blades thereof. The method comprises the following steps: S1, mounting a hanging beam tool on a first blade mounting interfaceof a hub; S2, lifting the hanging beam tool, and rotating the hub to enable second blade mounting interfaces to be at corresponding mounting positions; S3, mounting blades on the second blade mounting interfaces; S4, repeating the steps S2 and S3 until the blades are mounted on all the second blade mounting interfaces; S5, lifting the hanging beam tool, rotating the hub to enable the first blademounting interface to be in a dismounting position, and dismounting the hanging beam tool; and S6, mounting blades on the first blade mounting interface. According to the hoisting method, the hangingbeam tool is utilized, the hub is rotated by controlling the hanging beam tool, so that the blade mounting interfaces to be mounted are rotated to better mounting positions, the operation height of hoisting equipment is reduced, and the economic benefit is improved.
本发明公开了一种风力发电机及其叶片的吊装方法,其包括步骤:S1、安装吊梁工装于轮毂的第一叶片安装接口;S2、提吊所述吊梁工装,旋转所述轮毂使得第二叶片安装接口处于对应的安装位置;S3、于所述第二叶片安装接口进行叶片安装;S4、重复步骤S2、S3,直至所有的所述第二叶片安装接口均进行了叶片安装;S5、提吊所述吊梁工装,旋转所述轮毂使得所述第一叶片安装接口处于拆卸位置,拆除所述吊梁工装;S6、于所述第一叶片安装接口进行叶片安装。该吊装方法利用吊梁工装,通过控制吊梁工装实现轮毂的旋转,使待安装的叶片安装接口转到较佳的安装位置,降低了起吊设备的作业高度,提高了经济效益。
