The invention relates to the technical field of wind power generation, in particular to a hoisting method for a wind driven generator blade assembly. S1, the fixing device is detached, and the hoisting position is determined. And S2, the protection assembly and the adjusting assembly are installed. And S3, trying to hoist and adjusting the balance state. And S4, the front tool is disassembled, and lubricating treatment is conducted. And S5, the blades are adjusted to be aligned with the hub. And S6, the fastening assembly is installed and pre-tightened. And S7, the connecting pieces are symmetrically fastened step by step. And S8, the remaining blades are repeatedly installed. By marking on the basis of the gravity center point of the blade, combining with fixing of a balance beam lifting appliance and then finely adjusting the lifting point through trial lifting, the problem of lifting belt deviation caused by gravity center estimation through traditional experience is solved, the lifting torque offset is reduced, the stability of the blade hovering posture is improved, and the double cable wind ropes and the root control rope of the blade tip are adopted for cooperative adjustment. The swing amplitude of the blade tip under the high-altitude wind load is reduced, and the time consumed for aligning the blade root bolt is shortened to be within 30 minutes from 1-2 hours.
本发明涉及风力发电技术领域,具体是一种风力发电机叶片组对的吊装方法。S1:拆卸固定装置并确定起吊位置。S2:安装防护组件和调节组件。S3:试吊并调整平衡状态。S4:拆卸前工装并进行润滑处理。S5:调整叶片与轮毂对准。S6:安装紧固组件并进行预紧。S7:分步对称紧固连接件。S8:重复安装剩余叶片。通过基于叶片重心点标记并结合平衡梁吊具固定,然后通过试吊微调吊点,解决了传统经验估算重心导致的吊带偏移问题,使吊装扭矩偏移量降低,叶片悬停姿态稳定性提升,采用叶尖双缆风绳及根部控制绳协同调节,将高空风载下的叶尖摆动幅度降低,叶根螺栓对齐耗时从1‑2小时缩短至30分钟内。
