A lift system for a rotor blade of a wind turbine includes a lifting device having a structural frame body having a root end and a tip end. The root end supports a root cradle and the tip end supports a tip cradle. The root and tip cradles each have a profile that corresponds to at least one exterior surface of the rotor blade so as to receive and support at least a portion of the rotor blade. Due to a shape of the rotor blade, when the rotor blade is installed in the lifting device and lifted uptower, the rotor blade can experience an asymmetric loading. Accordingly, the lift system also includes a variable airflow assembly coupled to tip end of the lifting device. The variable airflow assembly includes at least one surface moveable between a plurality of positions having varying resistances so as to counteract the asymmetric loading.

    一种用于风力涡轮的转子叶片的提升系统包括提升装置,该提升装置具有结构框架主体,该结构框架主体具有叶根端部和叶尖端部。叶根端部支撑叶根支架,叶尖端部支撑叶尖支架。叶根支架和叶尖支架各自具有对应于转子叶片的至少一个外表面的轮廓,以便接收和支撑转子叶片的至少一部分。由于转子叶片的形状,当转子叶片安装在提升装置中并提升到塔架上时,转子叶片会经受不对称载荷。因此,提升系统还包括联接到提升装置的叶尖端部的可变气流组件。可变气流组件包括至少一个表面,其可在具有不同阻力的多个位置之间移动,以便抵消不对称载荷。
