Abstract
The invention relates to an assembly method for a vibration damper of a tower of a wind power plant, in which the vibration damper is switched into a transport state from a state of use. The vibration damper is connected to a structural component of the tower such that a damper mass of the vibration damper can be set in motion, during which movement the distance between the damper mass and a central axis of the tower varies. The vibration damper is switched into the transport state by tilting the vibration damper compared to the state of use. The invention also relates to an associated assembly system.
Claims18
A dis-assembly method for a vibration damper of a tower of a wind turbine comprising:
- moving the vibration damper from an in-use state to a transport state;
- and
- subsequently removing the vibration damper from the tower wherein,
- the vibration damper comprises a damper mass mounted to a frame,
- the frame is connected to a structural component of the tower and in
- the in-use state the vibration damper projects into an interior of the tower,
- in the in-use state, the damper mass can be set in motion relative to the frame by a drive such that a distance between the damper mass and a center axis of the tower changes, and
- the step of moving the vibration damper includes tilting the vibration damper relative to the in-use state.
A dis-assembly method for a vibration damper of a tower of a wind turbine comprising:
- moving the vibration damper from an in-use state to a transport state;
- and
- subsequently removing the vibration damper from the tower wherein,
- the vibration damper comprises a first damper mass and a second damper mass mounted to a frame,
- the frame is connected to a structural component of the tower,
- in the in-use state, the first damper mass and the second damper mass can be set in motion along opposite circular paths relative to the frame by a drive such that a distance between the first and second damper masses and a center axis of the tower change, and
- the step of moving the vibration damper includes tilting the vibration damper relative to the in-use state.
