Abstract

Provided is a guiding tool for a surface trimming device, including a main body with a front side base portion and a backside base portion, which are connected by at least one connection portion of the main body, wherein the main body exhibits a recess on a bottom side between the front side base portion and the backside base portion, wherein the main body includes a fixation device on a top side of the main body opposing the recess, wherein a surface trimming device is mountable to the fixation device in such manner that a movable device or trimmer of the surface trimming device is located in the recess between the front side base portion and the back side base portion.

First claim

The invention claimed is:

1. A guiding tool for a surface trimming device for trimming a protective layer and/or an adhesive layer on a wind turbine blade, the guiding tool comprising:
a main body with a front side base portion and a backside base portion, which are connected by two connection portions of the main body, so as to form a rectangular frame, wherein the main body comprises a recess on a bottom side between the front side base portion and the backside base portion and a fixation device on a top side of the main body opposing the recess and between the front side base portion and the backside base portion, wherein a surface trimming device is mountable to the fixation device in such manner that a movable trimming device of the surface trimming device is located in the recess between the front side base portion and the backside base portion, wherein the front side base portion and the backside base portion comprise a contact portion for contacting a surface of the wind turbine blade during trimming.

2. The guiding tool according to claim 1 , wherein the front side base portion and the backside base portion each comprises a left and a right contact portion for contacting the surface of the wind turbine blade during trimming.

3. The guiding tool according to claim 1 , wherein the fixation device is height-adjustable, so that a distance between an operative trimming portion of the movable trimming device and the lower edges of the front side base portion and the backside base portion is adjustable.

4. The guiding tool according to claim 1 , wherein the fixation device is adaptable for fixation of different trimming devices.

5. The guiding tool according to claim 2 , wherein the front side base portion and the backside base portion each comprises at least one first guiding roller forming the respective left and right contact portions.

6. The guiding tool according to claim 5 , wherein the main body comprises at least one guiding means comprising at least one second guiding roller attached to a connection arm of the guiding means, so that the second guiding roller is arranged distanced to the main body.

7. The guiding tool according to claim 5 , wherein the first guiding rollers are rotatable around first parallel axes and the second guiding roller is rotatable around a second axis arranged at an angle to the first axes.

8. The guiding tool according to claim 6 , wherein the connection arm is adaptable for adjusting the distance between the at least one second guiding roller and the main body and/or for adjusting the angle between the second axis or axes of the at least one second guiding roller and the first axes.

9. A trimming arrangement comprising the guiding tool according to claim 1 and a trimming device.

10. The trimming arrangement according to claim 9 , wherein the trimming device comprises a grinding disk or a cylindrical or a drum-shaped cutting bit as a movable trimming device.

11. The trimming arrangement according to claim 9 , wherein an operative trimming portion of the movable trimming device of a trimming device mounted to the fixation device is located at least sectionally above the lower edges of the front side base portion and the backside base portion of the main body of the guiding tool.

12. The trimming arrangement according to claim 11 , wherein a minimum distance between the operative trimming portion and the lower edges of the front side base portion and the backside base portion is between 0.05 mm and 1 mm or between 0.1 mm and 0.3 mm.

13. A guiding tool for a surface trimming device for trimming a wind turbine blade, comprising:
a main body with a front side base portion and a backside base portion, which are connected by two connection portions of the main body to form a frame, wherein the main body includes a recess on a bottom side between the front side base portion and the backside base portion and a fixation device on a top side of the main body opposing the recess and between the front side base portion and the backside base portion, wherein a surface trimming device is mountable to the fixation device in such manner that a movable trimming device of the surface trimming device is located in the recess between the front side base portion and the backside base portion, wherein at least one of the front side base portion and the backside base portion comprise a contact portion for contacting a surface of the wind turbine blade during trimming, wherein the front side base portion and the backside base portion each comprises at least one first guiding roller forming the contact portion, and wherein the main body comprises at least one guiding means comprising at least one second guiding roller attached to a connection arm of the guiding means, so that the second guiding roller is arranged distanced to the main body.
