Title: TOOL FOR TEMPORARILY CONNECTING A HUB ELEMENT AND A BLADE OF A WIND TURBINE
Abstract:
The invention relates to a tool (1) for temporarily connecting a hub element (2) and a blade (3) of a wind turbine for establishing a firm connection between the hub element (2) and the blade (3) when a slewing bearing (4), which is effectively arranged between the hub element (2) and the blade (3), is not activated. To obtain a stable but quick mountable and releasable connection between the hub element and the blade the invention suggests that the tool comprises: a plurality of clamping elements (5) which are arrangeable between an inner circumference of the hub element (2) and the blade (3) in the region of the slewing bearing (4), wherein each clamping elements (5) is designed to be connected with a part of the hub element (2) and a part of the blade (3) at a defined circumferential position; and a holding device (6) which holds the clamping elements (5) and which is designed to exert a radial pressure to the clamping elements (5) which is directed in an outward direction (R).
