Abstract

Provided is a support structure for a wind turbine blade and a method for manufacturing a support structure for a wind turbine blade The support structure includes a frame structure including a first section and a second section which are spaced apart with respect to each other along a first direction such that a section of a wind turbine blade is arrangeable in-between the first section and the second section. The support structure further includes two seesaw elements being pivotably fixed to a respective section and having a respective pivoting axis parallel to the first direction and four belt elements being fixed with their respective first end to a respective end of the respective seesaw element Furthermore, a respective second end of the respective belt element are each fixed to the respective other section of the frame structure.

First claim

The invention claimed is:

1. A support structure for a wind turbine blade comprising:
a frame structure comprising a first section and a second section which are spaced apart with respect to each other along a first direction such that a section of a wind turbine blade is arrangeable in-between the first section and the second section;
a first seesaw element being pivotably fixed to the first section, and having a first pivoting axis parallel to the first direction;
a second seesaw element being pivotably fixed to the second section, and having a second pivoting axis parallel to the first direction;
a first belt element being fixed with a first end of the first belt element to a first end of the first seesaw element;
a second belt element being fixed with a first end of the second belt element to a first end of the second seesaw element;
a third belt element being fixed with a first end of the third belt element to a second end of the first seesaw element and
a fourth belt element being fixed with a first end of the fourth belt element to a second end of the second seesaw element;
wherein the first end and the second end of the first seesaw element are on opposite sides relatively to the first pivoting axis;
wherein the first end and the second end of the second seesaw element are on opposite sides relatively to the second pivoting axis;
wherein a second end of the first belt element and a second end of the third belt element are each fixed to the second section of the frame structure, and a second end of the second belt element and a second end of the fourth belt element are each fixed to the first section of the frame structure.

2. The support structure according to claim 1 , wherein the second pivoting axis is arranged at the second section of the frame structure at a second height with respect to a support area of the support structure further wherein the second end of the second belt element is fixed to the first section of the frame structure at a fourth height with respect of the support area and the second end of the fourth belt element is fixed to the first section of the frame structure at the fourth height and the second height is larger than the fourth height.

3. The support structure according to claim 2 , wherein the first height and the second height are equal, and the third height and the fourth height are equal.

4. The support structure according to claim 1 , wherein the first pivoting axis is arranged at the first section of the frame structure at a first height with respect to a support area of the support structure further wherein the second end of the first belt element is fixed to the second section of the frame structure at a third height with respect to the support area, and the second end of the third belt element is fixed to the second section of the frame structure at the third height and the first height is larger than the third height.

5. The support structure according to claim 1 , further comprising:
a second deflexion element for deflecting the second belt element and
a fourth deflexion element for deflecting the fourth belt element,
wherein the second belt element extends from the first end of the second seesaw element ( 322 ) deflected around the second deflexion element to the first section, and
wherein the fourth belt element extends from the second end of the second seesaw element deflected around the fourth deflexion element to the first section.

6. The support structure according to claim 1 , wherein seen in a second direction of the support structure being perpendicular to the first direction, the first end of the second seesaw element and the second end of the second seesaw element are arranged in-between the first end of the first seesaw element and the second end of the first seesaw element, or
wherein seen in a second direction of the support structure being perpendicular to the first direction, the first end of the first seesaw element and the second end of the first seesaw element are arranged in-between the first end of the second seesaw-element and the second end of the second seesaw element.

7. The support structure according to claim 1 , wherein the first end of the first belt element is fixed to the first end of the first seesaw element by a pivotable joint such that the first end of the first belt element is pivotable around an axis of rotation being parallel to the first pivoting axis, wherein the first end of the third belt element is fixed to the second end of the first seesaw element by a pivotable joint such that the first end of the third belt element is pivotable around an axis of rotation being parallel to the first pivoting axis, wherein the first end of the second belt element is fixed to the first end of the second seesaw element by a pivotable joint such that the first end of the second belt element is pivotable around an axis of rotation being parallel to the second pivoting axis, and
wherein the first end of the fourth belt element is fixed to the second end of the second seesaw element by a pivotable joint such that the first end of the fourth belt element is pivotable around an axis of rotation being parallel to the second pivoting axis.

8. The support structure according to claim 1 , wherein the first end of the first belt element is fixed to the first end of the first seesaw element by a further pivotable joint such that the first end of the first belt element is pivotable around a further axis of rotation being perpendicular to the first pivoting axis, and extending parallel to a support area of the support structure, wherein the first end of the third belt element is fixed to the second end of the first seesaw element by a further pivotable joint such that the first end of the second belt element is pivotable around a further axis of rotation being perpendicular to the first pivoting axis, and extending parallel to the support area, wherein the first end of the second belt element is fixed to the first end of the second seesaw element by a further pivotable joint such that the first end of the second belt element is pivotable around a further axis of rotation being perpendicular to the second pivoting axis, and extending parallel to the support area, wherein the first end of the fourth belt element is fixed to the second end of the second seesaw element by a further pivotable joint such that the first end of the fourth belt element is pivotable around a further axis of rotation being perpendicular to the second pivoting axis, and extending parallel to the support area.
