The invention discloses a blade self-hoisting method for hoisting a blade. The blade self-hoisting method comprises the following steps: selecting a blade hoisting hole position and forming a hoisting hole; reinforcing the blade lifting hole by using a reinforcing plate; reinforcing cloth is used for reinforcing the blade lifting hole area; the lifting belt bypasses the blade lifting hole to lift and mount the blade; and the installed blade is subjected to lifting hole cover plate area reinforcement. According to the technical scheme, the blade lifting work can be carried out by changing the structure of the blade, namely adding the design of the blade lifting holes in the blade structure design link and winding the wide lifting belts around the blade lifting holes, design and machining of large-scale blade lifting tool equipment are omitted, meanwhile, the blade lifting holes are used for lifting, and the blade lifting efficiency is improved. And the high efficiency, the reliability and the safety of long blade hoisting are effectively ensured.

    本发明公开了一种用于叶片吊装的叶片自吊方法,包括以下步骤:选定叶片吊孔位置并开设吊孔;对叶片吊孔进行补强板补强;对叶片吊孔区域进行补强布补强;吊带绕过叶片吊孔进行叶片起吊和安装工作;对安装完成后的叶片进行吊孔盖板区域补强。上述技术方案通过改变叶片自身结构,即在叶片结构设计环节添加叶片吊孔的设计,使用宽的吊带绕过叶片吊孔即可进行叶片起吊工作,免除了大型叶片吊装工装设备的设计加工,同时通过利用叶片吊孔起吊,有效保证了长叶片吊装的高效性、可靠型与安全性。
