The invention relates to a hoisting device, in particular to a fine-adjustable hoisting base for hoisting a wind driven generator impeller. The hoisting base comprises a hoisting device main body, a first hoisting base body, a transition plate, a second hoisting base body, a hoisting belt, a main hoisting belt and an auxiliary hook tailing hoisting belt. One end of the hoisting device main body isrotationally connected with the first hoisting base body, the other end of the hoisting device main body is rotationally connected with one end of the transition plate, and the other end of the transition plate is rotationally connected with the second hoisting base body. Lifting lugs movably connected through floating pins are arranged at the corresponding positions of the hoisting device main body, the first hoisting base body and the transition plate, and the corresponding positions of the transition plate and the second hoisting base body. The hoisting belt and the main hoisting belt areinstalled on the hoisting device main body. The movable hoisting base is adopted, the installing angle can be adjusted slightly, hole aligning is facilitated in the hoisting base installing process, the hoisting device installing speed is increased, and thus the operation efficiency is improved. Meanwhile, an impeller assembly can be rotated and turned over conveniently.
本发明涉及一种吊具,具体涉及一种风力发电机叶轮吊装可微调吊座,包括吊具主体、第一吊座、过渡板、第二吊座、吊带、主吊带和副钩溜尾吊带;所述吊具主体的一端转动连接第一吊座,吊具主体的另一端转动连接过渡板的一端,过渡板的另一端转动连接第二吊座;所述吊具主体与第一吊座和过渡板、过渡板与第二吊座上对应位置设有利用浮动销活动连接的吊耳;所述吊带和主吊带安装在吊具主体上。本发明采用了活动式吊座,安装角度可以进行微调,便于吊座安装时对孔,提高了吊具安装速度,从而提升了作业效率;同时,便于叶轮总成旋转翻身。
