Rear rack of wind driven generator

The utility model relates to a rear frame of a wind driven generator, which comprises a main beam provided with a main beam connecting component, a main beam connecting component and a main beam connecting component, the auxiliary beams are separated from the main beam and provided with auxiliary beam connecting parts, and the main beam connecting parts can be fixedly connected with the auxiliary beam connecting parts. The rear rack of the wind driven generator is of a split type structure, the problem that the overall machining difficulty of a rear rack of a megawatt type is large is solved, the rear rack of the wind driven generator can be assembled and disassembled, the problem that the transportation width of the rear rack is limited is solved, the transportation efficiency is improved, the auxiliary beams and the cable-stayed beams in an interference area can be disassembled in advance in the air, and the transportation cost is reduced. Large components can directly fall down from the middle of the rear
