Embodiment Construction

[0059] figure 1 A perspective view of a blade 1 according to an embodiment is shown. figure 1 A clamp 1 is shown in and holds a blade 2 of a wind turbine. exist figure 2 is shown in Fixture 1 along the figure 1 Side view of direction 3 shown in . image 3 shows along the figure 1 Bottom view of direction 5 shown.

[0060] The clamp 1 comprises a first contact surface 7 and a second contact surface 9 . The first contact surface 7 and the second contact surface 9 are adapted to contact different parts of the surface of the blade 2 . In the illustrated embodiment, the first contact surface 7 contacts a part of the rear surface 11 of the blade 2 , while the second contact surface 9 of the clamp 1 contacts a part of the front surface 13 of the blade 2 . Although figure 1 with figure 2 A state of the clamp 1 is shown in which the first contact surface 7 contacts a part of the rear surface 11 and the second contact surface 9 of the clamp contacts a part of the front surfac...

Abstract

The present invention discloses a clamp for clamping a blade (2) for a wind turbine, wherein the clamp comprises a first contact surface (7) adapted to contact a portion of a surface of the blade; a second contact surface (9) adapted to contact another portion of the surface of the blade, the second contact surface being displacable relative to the first contact surface; and a bar (45) connected in an adjustable orientation relative to the first contact surface. Further a method of installing wind turbine blades at a hub rotatable around a rotation axis along a horizontal direction is provided.

Description

technical field [0001] The invention relates to a clamp for clamping a blade of a wind turbine and a method of mounting a wind turbine blade at a hub. In particular, the present invention relates to a clamp for clamping a blade of a wind turbine and a method of mounting a wind turbine blade suitable for assembling a wind turbine that does not allow rotation of its hub by an external actuator. Background technique [0002] A wind turbine is a machine that converts the kinetic energy of moving air, such as wind, into mechanical energy. Mechanical energy can eg be converted into electrical energy by using a generator. Commonly used are horizontal axis wind turbines comprising a rotor shaft (rotatable about a horizontal axis) and a nacelle on top of a tower. At the rotor shaft, the hub is mounted to the attached rotor blades. The blades may have a length from 20 to 70m and the towers may have a height of 60 to 100m or more. Modern wind turbines used in wind farms may have th...
