The invention provides a blade hoisting fixture. The blade hoisting fixture comprises a pitching rotation mechanism and a blade clamp, wherein the pitching rotation mechanism comprises a support frame, a pitching rotation shaft and a rotation shaft drive assembly; the pitching rotation shaft is rotatably arranged on the support frame, a first end of the pitching rotation shaft is connected with the blade clamp, and a second end of the pitching rotation shaft is connected with the rotation shaft drive assembly; the rotation shaft drive assembly comprises a turbine and a worm driving the turbineto rotate; the turbine is arranged in a manner of being coaxial with the pitching rotation shaft and fixed to the second end of the pitching rotation shaft, the turbine is driven to rotate through the worm, and then the blade clamp is driven to rotate, so that a pitching angle of the blade is adjusted; and therefore, the blade hoisting fixture is capable of clamping the blade to rotate together,and a turning gear does not need to be additionally used in a blade installation process.
本公开提供一种叶片吊装工装,叶片吊装工装包括俯仰旋转机构和叶片夹具,俯仰旋转机构包括支撑框架、俯仰旋转轴和旋转轴驱动组件,俯仰旋转轴可旋转地设置在支撑框架上,且俯仰旋转轴的第一端与叶片夹具连接,俯仰旋转轴的第二端与旋转轴驱动组件连接,旋转轴驱动组件包括涡轮和驱动涡轮旋转的蜗杆,涡轮与俯仰旋转轴同轴设置并固定于俯仰旋转轴的第二端,以通过蜗杆带动涡轮旋转,进而带动叶片夹具旋转,从而调节叶片的俯仰角度,因此叶片吊装工装能够夹持叶片一同旋转,也就无需在叶片安装过程中额外使用盘车机构。
