The invention discloses a wind generating set blade lifting device and a lifting method thereof. The wind generating set blade lifting device comprises an upper sling support, a lower sling support, aconnection hinge pin and a hinge pin disassembly-assembly mechanism. The upper sling support is used for being connected with a lifting hook. The lower sling support comprises a first connection rod,a second connection rod and a blade support plate connecting the first connection rod with the second connection rod. The upper end of the first connection rod is hinged to the lower portion of one side of the upper sling support. The upper end of the second connection rod is detachably connected to the lower portion of the other side of the upper sling support through the connection hinge pin. The hinge pin disassembly-assembly mechanism is used for controlling the position of the connection hinge pin so as to control the connection state of the second connection rod and the upper sling support. According to the wind generating set blade lifting device and the lifting method thereof, the upper sling support and the second connection rod can be automatically separated after a blade is installed, thus the blade is separated from the upper sling support and the lower sling support, the structure is simple, and cost is low.
本发明公开了一种风力发电机组叶片吊装装置及其吊装方法。该装置包括:上吊具支架、下吊具支架、连接销轴和销轴拆装机构;上吊具支架用于连接吊钩;下吊具支架包括第一连接杆、第二连接杆、以及连接第一连接杆和第二连接杆的叶片支撑板,第一连接杆上端铰接在上吊具支架的一侧下部,第二连接杆上端通过连接销轴可分离地连接在上吊具支架的另一侧下部;销轴拆装机构用于控制连接销轴的位置,以控制第二连接杆和上吊具支架的连接状态。本发明的风力发电机组叶片吊装装置及其吊装方法能够在叶片完成安装后实现上吊具支架和第二连接杆的自动分离,从而实现叶片与上吊具支架及下吊具支架的分离,结构简单成本低。
