Abstract

There is provided an apparatus for rotating and/or displacing a rotor blade of a wind power installation. The apparatus has at least one main body for at least partially embracing the rotor blade with a longitudinal, at least one contact portion for bearing against the rotor blade and at least one main frame for receiving the main body for rotation of the main body about the longitudinal axis and/or for displacement of the main body. The main body has at least one pivotably mounted pivotal portion for engagement at at least one side of the rotor blade.

First claim

The invention claimed is:

1. An apparatus for handling a wind power installation rotor blade with a longitudinal axis, the apparatus comprising:
at least one main body for at least partially holding the rotor blade, the at least one main body having at least one pivotably mounted pivotal portion for engagement with at least one side of the rotor blade;
at least one main frame for rotatably receiving the at least one main body; and
at least one fixing unit for fixing to a wind power installation rotor blade that is located in the apparatus, the at least one fixing unit having a first portion and a second portion, wherein the first portion is provided at a first end of the at least one main body and the second portion is provided at a second end of the at least one main body, and wherein the at least one fixing unit is adapted to receive a fixing bolt on or in the wind power installation rotor blade, wherein the first and second portions, respectively, have a locking pin for locking the fixing bolt when the wind power installation rotor blade is introduced into the apparatus.

2. The apparatus according to claim 1 wherein the at least one main body is of a C-shaped configuration.

3. The apparatus according to claim 2 wherein the at least one main frame has at least two rolling bearings for rotatably receiving the at least one main body.

4. The apparatus according to claim 1 wherein the at least one main frame has a support means for carrying the main frame and wheels for displacement of the apparatus on a ground surface or on a rail system.

5. The apparatus according to claim 1 wherein the at least one main frame has at least one drive means for rotating the at least one main body for at least one of longitudinal and transverse displacement of the at least one main body.

6. The apparatus according to claim 1 wherein at least one of the at least one main body and the at least one main frame has a carrier region for hangingly engaging a hook.

7. An apparatus for handling a wind power installation rotor blade with a longitudinal axis, the apparatus comprising:
at least one main body for at least partially holding the rotor blade, the at least one main body having at least one pivotably mounted pivotal portion for engagement with at least one side of the rotor blade, wherein the at least one pivotal portion has a locking pawl comprising a first recess, a second recess and a locking pin for locking a rotor blade fixing unit, wherein the rotor blade fixing unit comprises a first projection and a second projection for engaging with the first recess, the locking pin engaging with the second recess for locking; and
at least one main frame for rotatably receiving the at least one main body.

8. A system for handling a wind power installation rotor blade, the system comprising:
a wind power installation rotor blade comprising:
a longitudinal direction;
a suction side and a pressure side; and
a fixing bolt that extends between the suction side and the pressure side and projects beyond the suction side and the pressure side; and
an apparatus comprising:
at least one main body for at least partially holding the wind power installation rotor blade, the at least one main body having at least one pivotably mounted pivotal portion for engagement with at least one side of the wind power installation rotor blade;
at least one main frame for rotatably receiving the at least one main body; and
at least one fixing unit located on the apparatus for fixing to the wind power installation rotor blade, the at least one fixing unit having a first portion and a second portion, wherein the first portion is provided at a first end of the at least one main body and the second portion is provided at a second end of the at least one main body, and wherein the at least one fixing unit is adapted to receiving the fixing bolt of the wind power installation rotor blade, wherein the first and the second portions, respectively, have a locking pin for locking the fixing bolt when the wind power installation rotor blade is introduced into the apparatus.
