Wind turbine support assembly and wind turbine
A wind turbine support assembly includes a bedframe and a support structure, wherein the bedframe is adapted for attaching the support assembly to a wind turbine tower, wherein the support structure includes at least one beam, wherein a web section of the beam is attached to an attachment area of the bedframe by a bolted connection including at least one bolt arranged perpendicular to the web section, wherein on the side of the web section opposite to the attachment area at least one retaining means is arranged for holding a bolt or a nut, which is attached to the bolt, in a non-rotatable manner.
1. A wind turbine support assembly comprising a bedframe and a support structure, wherein the bedframe is configured for attaching the support assembly to a wind turbine tower, wherein the support structure comprises at least one beam, wherein a web section of the beam is attached to an attachment area of the bedframe by a bolted connection comprising a plurality of bolts arranged perpendicular to the web section, wherein on a side of the web section opposite to the attachment area at least one retaining means is arranged for holding a nut, which is attached to a respective bolt of the plurality of bolts, in a non-rotatable manner, wherein the retaining means comprises at least one retainer plate having a plurality of non-circular openings for accommodating a respective nut having an outer circumference with at least one non-circular section, wherein the retaining means comprises a further retainer plate arranged in parallel and at a distance to the retainer plate, wherein the further retainer plate comprises a plurality of further openings, and wherein each nut extends through a respective non-circular opening of the retainer plate and a respective further opening of the further retainer plate.
2. The wind turbine support assembly according to claim 1 , wherein the at least one retaining means is arranged on an outside of the support structure facing away from the bedframe.
3. The wind turbine support assembly according to claim 1 , wherein the beam is attached to the attachment area at an outside of the bedframe.
4. The wind turbine support assembly according to claim 1 , wherein the cross-sectional area of a section of the nut accommodated in the further opening is larger in at least one dimension than the non-circular opening in the retainer plate, wherein the further retainer plate is arranged between the web section of the beam and the retainer plate.
5. The wind turbine support assembly according to claim 1 , wherein the support structure comprises two beams, which are each attached to one of two opposing attachment areas of the bedframe.
6. The wind turbine support assembly according to claim 1 , wherein the attachment area abuts only the web section of the beam or that the attachment area abuts the web section of the beam and at least one flange section of the beam.
7. The wind turbine support assembly according to claim 1 , wherein at least one supporting element is mounted to at least one side of the web section, wherein the at least one supporting element supports the web section and a flange section of the beam against each other.
8. The wind turbine support assembly according to claim 7 , wherein at least one wedge-shaped compensation element is arranged between the flange section and the at least one supporting element.
9. The wind turbine support assembly according to claim 1 , wherein the beam is an I-beam.
10. The wind turbine support assembly according to claim 1 , wherein a section of a canopy is attachable or attached to the bolted connection and/or wherein at least one canopy attachment means is attached to the bolted connection and/or to the retaining means.
11. A wind turbine comprising the wind turbine support assembly according to claim 1 .
