The invention discloses a gravity center self-adjusting type blade air assembly lifting appliance which comprises a dual self-rotating mechanism. The dual self-rotating mechanism comprises a large-range rotating arm, a small-range rotating arm is hinged to the large-range rotating arm, and a rotating arm fixing base is hinged to the small-range rotating arm. A swing arm assembly is arranged at the top end of a tray, and clamping assemblies are symmetrically arranged at two ends of the tray. The swing arm assembly comprises a swing arm support and a swing arm hydraulic cylinder. Each clamping assembly comprises a clamp body, wherein a rotary clamping arm and a clamping hydraulic cylinder are hinged to the clamp body, the clamping hydraulic cylinder is hinged to the rotary clamping arm, an upper clamp blade shape follow-up protection module is fixedly connected to the rotary clamping arm, and a lower clamp blade shape follow-up protection module is fixedly connected to the clamp body. The device solves the problem that the gravity center changes during offshore high-altitude large-rated-load single-blade assembly, operation can be carried out in a limited hoisting space, a damaged blade can be maintained and replaced, and the working condition requirement of offshore installation of a wind turbine generator is met.

    本发明公开一种重心自调节式叶片空中组对吊具,包括双重自旋转机构,双重自旋转机构包括大范围旋转臂,大范围旋转臂铰接有小范围旋转臂,小范围旋转臂铰接有旋转臂固定座;托盘顶端设有摆臂组件,托盘两端对称设有夹持组件;摆臂组件包括摆臂支座和摆臂液压缸;夹持组件包括夹钳体,夹钳体分别铰接有旋转夹臂和夹持液压缸,夹持液压缸与旋转夹臂铰接,旋转夹臂上固接有上夹钳叶片随形保护模块,夹钳体上固接有下夹钳叶片随形保护模块。本装置解决了海上高空大额载单叶片组对时重心变化的问题,可在有限的吊装空间进行作业,还可以对损坏的叶片进行维修更换,满足了海上安装风电机组的工况需求。
