Detailed Description

The following describes the embodiments of the present invention with reference to fig. 1 and fig. 2.

Fig. 1 and 2 schematically show a large-scale basket type coil wrapping support and platform position device of a permanent magnet direct-drive wind driven generator according to an embodiment of the invention. As shown in fig. 1 and 2, the large-scale basket type coil wrapping support and platform position device of the permanent magnet direct-drive wind turbine generator comprises at least two groups of support assemblies 1.

Each set of support assemblies 1 comprises a support roller 11, a support base 12 and two moving wheels 13. The support base 12 includes two parallel vertical support rods 121. A connecting rod body 122 is arranged between the two supporting rod bodies 121, and the connecting rod body 122 is close to the bottom of the supporting rod bodies 121. The connecting rod body 122 is used for reinforcing the two support rod bodies 121. The supporting base 12 is fixed by bolts or nuts, and generally adopts an external thread structure. A roller fixing shaft 123 is provided between the tops of the two support rod bodies 121. The roller fixing shaft 123 is movably sleeved with a supporting roller 11. The support base 12 is used for supporting the roller 11 structure. The supporting rollers 11 are unpowered rollers. The diameter of the supporting roller 11 is matched with the weight of the coil 3, and the supporting roller is used for supporting the coil 3 and can rotate freely according to the moving condition of the coil 3.
