Abstract[English]
The invention provides a method for handling a blade (11) of a horizontal axis wind turbine (1), wherein the wind turbine comprises a tower (14), a nacelle (15) mounted on the tower, and a rotor hub (18) mounted to the nacelle, wherein the blade is elongated and extends from a blade root (111) to a blade tip (112), wherein, when the blade is mounted to the hub, a circular blade mounting flange (182) of the hub is in contact with the blade root (111), the method comprising - arranging a plurality of blade guide devices (411-414) so as to be fixed in relation to the hub (18), and distributed in a circumferential direction of the blade mounting flange (182), and so that contacts are provided between the blade (11) and contact devices (4105) of the blade guide devices (411-414), which contacts are provided at the blade root (111), - engaging a blade supporting arrangement (301) with the blade (11), - supporting the blade (11) by means of the engaged blade supporting arrangement (301), - driving at least one of the contact devices (4105) which are in contact with the blade so as to move the supported blade towards or away from the blade mounting flange (182).[French]
L'invention concerne un procédé de manipulation d'une pale (11) d'une éolienne à axe horizontal (1) ; l'éolienne comprend une tour (14), une nacelle (15) montée sur la tour, et un moyeu de rotor (18) monté sur la nacelle ; la pale est allongée et s'étend d'un pied de pale (111) à une pointe de pale (112) ; lorsque la pale est montée sur le moyeu, une bride de montage de pale circulaire (182) du moyeu est en contact avec le pied de pale (111) ; le procédé comprend : l'agencement d'une pluralité de dispositifs de guidage de pale (411-414) de manière à être fixés par rapport au moyeu (18), et répartis dans une direction circonférentielle de la bride de montage de pale (182), et de telle sorte que des contacts sont disposés entre la pale (11) et des dispositifs de contact (4105) des dispositifs de guidage de pale (411-414), lesquels contacts étant disposés au niveau du pied de pale (111), - la mise en prise d'un agencement de support de pale (301) avec la pale (11), - le support de la pale (11) au moyen de l'agencement de support de pale en prise (301), et - l'entraînement d'au moins l'un des dispositifs de contact (4105) qui sont en contact avec la pale de façon à déplacer la pale supportée vers ou à l'opposé de la bride de montage de pale (182).
