Abstract
A turning device to rotate the rotatable part of a wind turbine that comprises a stationary part and a rotatable part is described. The rotatable part is rotatable with respect to the stationary part of the wind turbine, and the stationary part is located within a nacelle, wherein the nacelle is at least partially enclosed by a housing. The turning device comprises a first lever and a second lever that is detachably attached to the rotatable part of the wind turbine. The first lever and the second lever reach from inside the housing of the nacelle through an opening to the outside of the nacelle, so that the drive is located outside of the housing of the nacelle, when the turning device is attached to the wind turbine.
Claims14
A turning device to rotate a rotatable part of a wind turbine, comprising:
- the wind turbine including a stationary part and the rotatable part;
- whereby the rotatable part is rotatable with respect to the stationary part of the wind turbine;
- whereby the stationary part is located within a nacelle;
- whereby the nacelle is at least partially enclosed by a housing;
- whereby the rotatable part comprises a hub of a rotor of the wind turbine;
- whereby the turning device is detachably attached to the wind turbine to rotate the rotatable part with respect to the stationary part;
- whereby the turning device comprises a first lever that is detachably attached to the stationary part of the wind turbine;
- whereby the turning device comprises a second lever that is detachably attached to the rotatable part of the wind turbine;
- and
- whereby the turning device comprises a drive that is prepared and arranged in a way to move the first lever with respect to the second lever to rotate the rotatable part of the wind turbine with respect to the stationary part;
- wherein the first lever and the second lever are arranged in a way that they reach from an inside of the housing of the nacelle through an opening to an outside of the nacelle so that the drive is located outside of the housing of the nacelle when the turning device is attached to the wind turbine.
