INTERNAL ASSEMBLY OF LADDER FOR HUB OF ROTOR OF WIND TURBINE Russian patent published in 2020 - IPC F03D1/06 F03D80/00 

FIELD: turbines or turbomachines.

SUBSTANCE: invention relates to a rotor hub for a wind turbine. Rotor hub for wind turbine includes housing having flanges for blades and access windows located at a distance from flanges for blades, and a ladder assembly extending in the hub housing inner part. Ladder assembly contains platforms, each of which forms a flat surface and in circumferential direction is aligned with the corresponding one of the specified access windows. Ladder assembly comprises a connecting frame passing between each pair of adjacent platforms so that it connects adjacent platforms to each other. Connecting frame extends along length along support line set between adjacent platforms. Platforms are located relative to each other so that the support line passes at an angle different from the right angle relative to the flat surfaces formed by the adjacent platforms.

EFFECT: invention is aimed at safety of access to an internal part of a hub.
