The invention discloses a hoisting device for assembling fan blades of a large wind driven generator. The hoisting device comprises a crane, and a steel cable is arranged on a cantilever of the crane; the connecting assembly comprises a connecting piece fixedly connected with the steel cable and a detaching piece connected with the connecting piece, a connecting column is arranged at the end of the connecting piece, an annular groove is formed in the connecting column along the circumference, a connecting hole is formed in the detaching piece, a sliding groove extending in the radial direction is formed in the side face of the connecting hole, a sliding block is arranged in the sliding groove, and the sliding block is connected with the connecting column. First springs are arranged at the bottoms of the sliding blocks and the bottoms of the sliding grooves. The lifting hook is fixedly connected with the dismounting piece; in order to hang blades of different sizes and weights, lifting hooks of different specifications need to be adapted, so that the lifting hooks can be replaced through the connecting assemblies, the replacement process is convenient, and connection is firm.
