Embodiment Construction

[0095] The illustrations in the figures are schematic. It should be noted that in different figures, similar or identical elements are provided with the same reference signs.

[0096] figure 1 A side view of a replacement device 100 according to an exemplary embodiment is shown.

[0097] The changing device 100 includes three capstans 110, a linear guide 120 and a motor 130 including gears. The changing device 100 further comprises a first fork element 151 and a second fork element 152 which are guided together along the linear guide rail 120 via a plurality of bearings 125 . The first fork element 151 and the second fork element 152 are each coupled at their respective free ends to an interface fixture 155 which interconnects the first fork element 151 with the second fork element 152 . Furthermore, the first fork element 151 and the second fork element 152 may be coupled to a stator segment carriage 161 , which is slidable relative to the linear guide rail 120 and include...

Abstract

The present invention describes a method for removing or installing a stator segment (981) of a generator being installed in a nacelle of a wind turbine, and an exchange device (100) for removing or installing a stator segment (981) of a generator installed in a nacelle of a wind turbine. The method comprises coupling a lifting mechanism (110) of an exchange device (100) to a plurality of liftingropes (512), with the plurality of lifting ropes (512) being fixed to a hub (471) of the wind turbine; self-lifting the exchange device (100) to the hub (471) by the lifting mechanism (110); fasteningthe exchange device (100) to the hub (471); rotating the hub (471) such that the exchange device (100) is aligned with the stator segment (981) to be removed; and handling the stator segment (981) between a stator of the generator and the exchange device (100) for removing or installing the stator segment (981).

Description

technical field [0001] The invention relates to the field of removing or installing stator segments of generators installed in the nacelle of a wind turbine. In particular, the invention relates to a method for removing or installing a stator section of a generator installed in a nacelle of a wind turbine, and for removing or installing a stator of a generator installed in a nacelle of a wind turbine Segment replacement device. Background technique [0002] Today, stator segments in generators of wind turbines are replaced by removing the generator and stator segments in a workshop. [0003] For example, nowadays, methods are known for removing stator components from a generator installed at the nacelle of a wind turbine. The method comprises: transferring a stator component from a stator frame structure of an electrical generator to a component replacement tool installed at a hub of a wind turbine; transporting the stator component from the replacement tool to delivery eq...
