The invention discloses a lossless rapid automatic adjustable lifting appliance. The lifting appliance comprises a lifting appliance top plate, supporting columns, a lifting appliance bottom plate, ascrew nut pair and a movable top plate, wherein the lifting appliance top plate and the lifting appliance bottom plate are fixedly connected with upper ends and lower ends of the supporting columns; adrive screw of the screw nut pair is arranged in parallel with the support columns, the movable top plate is fixedly connected with a nut of the screw nut pair, the drive screw rotates, and the movable top plate moves up and down along the drive screw and the support columns together with the nut. The lifting appliance further comprises at least three groups of lifting appliance supporting arms pressed on the inner wall of a wind power hub, the lifting appliance supporting arms are uniformly arranged around the movable top plate, each lifting appliance supporting arm comprises a middle arm and a large arm, one end of each middle arm is rotatably connected with the movable top plate through a connecting bolt, and one end of each large arm is rotatably connected with the lifting sling bottom plate through a connecting bolt. According to the lossless rapid automatic adjustable lifting appliance, the wind power hub can be lifted from a windward port or a main shaft hole.
Description
technical field [0001] The invention relates to a non-destructive, fast and automatically adjustable hoist, which belongs to the technical field of wind power manufacturing. Background technique [0002] Due to the different models of wind turbines, the weights vary. The currently used hoisting method for wind turbine hubs is hoisting with iron cables. Since the shape of the wind turbine hub is close to the hollow spherical shape, and the main shaft hole, windward opening and three fan blade holes are opened, the main shaft hole and the windward opening are located on the same axis, the spreader has no stressed suspension point, and the iron cable is in contact with the workpiece, which is easy to cut Workpieces increase scrap rates. The hoisting process is complex and inefficient, which increases the work intensity and labor cost, inevitably prolongs the production cycle of the workpiece, and reduces the international competitiveness of the product. Therefore, there is a...
