Abstract

An aligning tool in the field of wind turbines is provided. The aligning tool has a first and second section. The second section has an outside diameter tapering down in a direction away from the first section. The aligning tool is connected to a fastener and can easily catch a corresponding hole.

First claim

The invention claimed is:

1. A set in a field of a wind turbine, comprising:
a first part comprising at least one fastener, wherein the first part is a foundation of the wind turbine, wherein the fastener is a bolt, wherein the foundation has at least one row of circularly arranged bolts, the bolts each comprising a threaded shank sticking out upwards from a concrete body of the foundation;
a second part comprising at least one hole, wherein the second part is a tower of the wind turbine, the tower having at least one row of circularly arranged holes; and
at least one aligning tool,
each aligning tool adapted to align the at least one hole and the at least one fastener for insertion of the at least one fastener into the at least one hole, each aligning tool comprising:
a first section adapted for connecting to the at least one fastener, the first section comprising an inner thread adapted to be screwed onto a threaded shank; and
a second section having an outside diameter continuously tapering down in a direction away from the first section, the second section having a first outside diameter corresponding to the inside diameter of the hole and a second outside diameter smaller than the first outside diameter, the second section tapering down from the first and the second diameter.

2. The aligning tool according to claim 1 , wherein the first section comprises a receptacle to receive the fastener.

3. The aligning tool according to claim 1 , wherein the geometry is adapted to apply a torque for screwing the first section onto the fastener.

4. The aligning tool according to claim 3 , wherein the geometry is adapted to engage with a wrench or a screwdriver.

5. The aligning tool according to claim 4 , wherein the geometry is formed as a hexagon head.

6. The aligning tool according to claim 5 , wherein the hexagon head adjoins an end of the second section pointing away from the first section.

7. The aligning tool according to claim 1 , wherein the first section and the second section comprise a smoothly contoured outer rocket-shaped surface.
