ASSEMBLING TOOL FOR ROTOR END COVER PLATE OF LARGE PERMANENT MAGNET DIRECT DRIVING WIND TURBINE

WIPO Patent Application WO/2021/088143

A1

An assembling tool for a rotor end cover plate of a large permanent magnet direct driving wind turbine, comprising several sets of support frames (1) distributed in a circular ring shape; any one support frame (1) comprises a support base (11), an axial ascending and descending assembly (12) and a bearing plate (13); the axial ascending and descending assembly (12) can drive a rotor end cover plate (01) to ascend and descend in the axial direction and adjust the axial distance between the rotor end cover plate (01) and a rotor support (02); a rolling body (14) provided on the bearing plate (13) can support the circumferential rotation of the rotor end cover plate (01), which facilitates the alignment of mounting holes of the rotor end cover plate (01) and mounting holes of the rotor support. The rotor end cover plate (01) assists the support frames (1) achieving assembly, thus avoiding manually hoisting the rotor end cover plate (01) and reducing the risk of dropping the rotor end cover plate (01), while reducing the difficulty of assembly of the rotor end cover plate (01); thus, the labor intensity is low, and the safety is high. Therefore, the assembling tool for the rotor end cover plate (01) of the large permanent magnet direct driving wind turbine can simultaneously increase the efficiency of assembly and the safety of assembly.
