Protective fixing device for nacelle of wind driven generator

The utility model belongs to construction auxiliary devices for wind driven generators and provides a protective fixing device for a nacelle of a wind driven generator. The protective fixing device is characterized by being composed of a base, a connection flange and a vertical supporting frame. The base is a rectangular steel structure frame formed by installing and welding a front beam, a rear beam, a left carling and a right carling, a middle carling is welded between the front beam and the left section of the rear beam, supporting beams are symmetrically welded among the left section of the front beam, the left section of the rear beam, the front section of the left carling and the rear section of a middle carling respectively, the connection flange is connected to the inner sides of the four supporting beams, and the vertical supporting frame is vertically arranged in the middle of the right carling of the base. The vertical supporting frame is mainly formed by installing and welding a bottom plate, a vertical face plate and a top plate. An oblong connection hole is formed in the top plate, and the nacelle is fixedly arranged on the protective fixing device, so that a good protective function can be well achieved. Furthermore, the nacelle is integrally hoisted, thereby being safe and convenient.
