Abstract

A bracket for a transport frame, configured to hold a hub of a wind turbine in place at the transport frame during transport of the hub, the bracket holding the hub during the transport of the hub and mechanically connecting a holding device and the transport frame for attaching the holding device at the transport frame, for moving the holding device relative to the transport frame, and for moving a contacting portion of the holding device against the hub, which is arranged in a predetermined position on the transport frame is provided. A transport frame is also provided that includes, at least one bracket.

First claim

The invention claimed is:

1. A bracket for a transport frame, configured to hold a hub of a wind turbine in place at the transport frame during transport of the hub, comprising:
a holding means for holding the hub during the transport of the hub; and
a tensioning means mechanically connectable with the holding means and the transport frame for attaching the holding means at the transport frame, for moving the holding means relative to the transport frame, and for moving a contacting portion of the holding means against the hub, which is arranged in a predetermined position on the transport frame;
wherein the tensioning means comprises at least one screw to be screwed into the holding means for attaching the holding means at the transport frame, for moving the holding means relative to the transport frame, and/or for moving the contacting portion of the holding means against the hub as soon as the hub is placed in the predetermined position on the transport frame.

2. The bracket according to claim 1 , wherein the holding means comprises an L-shaped or essentially L-shaped base portion with an attaching portion for the mechanical connection with the tensioning means and the contacting portion.

3. The bracket according to claim 2 , wherein the base portion comprises a stabilization means receiving part to receive a stabilization means of the bracket to stabilize the holding means at the transport frame when the holding means is pressed against the hub, further wherein the stabilization means receiving part is configured to receive the stabilization means in a direction perpendicular to a moving direction of the contacting portion against the hub.

4. The bracket according to claim 2 , wherein the L-shaped or essentially L-shaped base portion includes a wedge-shaped receiving portion at an end section of the base portion for guiding the hub into position at the transport frame.

5. A transport frame for holding a hub of a wind turbine in place during transport of the hub, comprising at least one bracket according to claim 2 .

6. The transport frame according to claim 5 , further comprising a main body with a mounting portion, wherein the mounting portion is attached to the main body, wherein the tensioning means is provided to be mechanically connectable with the holding means and the mounting portion for attaching the holding means at the transport frame.

7. The transport frame according to claim 6 , wherein the mounting portion is integrally connected with the main body.

8. The transport frame according to claim 6 wherein the base portion comprises a guiding part that is flush-mount to a counter guiding part of the main body when moving the base portion and/or the contacting portion of the holding means against the hub.

9. The transport frame according to claim 6 , wherein the main body comprises a ring-shaped or essentially ring-shaped supporting portion for supporting the hub on the transport frame, wherein a normal vector of the supporting portion extends orthogonally to a normal vector of the contacting portion.
