The invention provides a blade hoisting tool. The blade hoisting tool comprises a hanger, a variable pitch rotation mechanism and a blade clamp, wherein the variable pitch rotation mechanism comprisesa support frame, a variable pitch rotation shaft and a variable pitch drive assembly, the variable pitch rotation shaft is arranged on one side of a width direction of the support frame, the variablepitch rotation shaft is rotatably arranged at the lower end of the hanger, the blade clamp is connected to the front end of the support frame, and the variable pitch drive assembly comprises a variable pitch worm gear and a variable pitch worm for driving the variable pitch worm gear to rotate. The variable pitch worm gear and the variable pitch rotation shaft are coaxially arranged, the variablepitch worm gear is fixed to the variable pitch rotation shaft, such that the variable pitch worm gear is driven to rotate by the variable pitch worm, then the variable pitch rotation shaft is drivento rotate relative to the hanger, the support frame and the blade clamp are driven to rotate around the variable pitch rotation shaft, and variable pitch operation is performed on blades clamped on the blade clamp.

    本公开提供一种叶片吊装工装,叶片吊装工装包括吊架、变桨旋转机构以及叶片夹具,变桨旋转机构包括支撑框架、变桨旋转轴以及变桨驱动组件,变桨旋转轴布置在支撑框架的宽度方向的一侧,且变桨旋转轴可转动地设置于吊架的下端,叶片夹具连接于支撑框架的前端,变桨驱动组件包括变桨涡轮和驱动变桨涡轮旋转的变桨蜗杆,变桨涡轮与变桨旋转轴同轴设置并固定于变桨旋转轴上,以通过变桨蜗杆带动变桨涡轮旋转,进而带动变桨旋转轴相对吊架旋转,以带动支撑框架和叶片夹具绕变桨旋转轴旋转,以使夹持在叶片夹具上的叶片进行变桨操作。
