Embodiment Construction
[0031] figure 1 The device and method for operating, assembling or disassembling components of a wind power plant and a wind power plant 1 under construction are shown in a schematic overview. Here, the wind power plant 1 consists of a base 3, a tower 4 and different functional units (of which a hub 5 with rotor blades 6 and a nacelle 7 can now be seen) in a known manner. According to this figure, the tower body 4 is here divided into two segments 4 a, 4 b, which are connected to each other by an intermediate piece 8. In principle, the tower body 4 can be composed of cast-in-place concrete, prefabricated concrete or steel, or be built with a mixed structure of different materials. Preferably, the lower section 4a of the tower body is composed of a concrete prefabricated part, which supports each other between the middle part 8 and the base 3, and the steel as the second section 4b is supported on the lower section. For the mast, the second section can be one piece or can also ...

Abstract
A device (2) for handling, mounting or demounting components (K, 5, 6, 7) of a wind turbine (1), in particular rotor blades (6) and / or a nacelle (7), with the aid of a crane (9) comprises a support (14) which can be connected to the crane (9) while being movable in the direction of a longitudinal axis (15) of said crane, and at least one guying device (16), preferably a guy cable (16a), which is connected at its first end to the movable support (14) and which can be connected by its second end to the component (K, 5, 6, 7) of the wind turbine (1) in order to stabilze the position of the component (K, 5, 6, 7) during handling and mounting. The guying device (16) is connected to the support (14) while being rotatable about the longitudinal axis (15) of the crane (9), preferably being rotatable through at least 90 degrees, more preferably being rotatable through at least 360 degrees, particularly preferably being rotatable through at least 380 degrees. In a method for handling, mounting or demounting components (K, 5, 6, 7) of a wind turbine (1), in particular rotor blades (6) and / or a nacelle (7), with the aid of a crane (9), the position of the component (K, 5, 6, 7) during handling and mounting or demounting is stabilized by means of at least one guying device (16), and the at least one guying device (16) is moved in the direction of a longitudinal axis (15) of the crane (9) during a vertical lifting movement of the component (K, 5, 6, 7). Before and / or during and / or after a vertical lifting movement of the component (K, 5, 6, 7), the at least one guying device (16) is rotated about the longitudinal axis (15) of the crane (9).
Description
Technical field [0001] The invention relates to a device for operating, assembling or disassembling components of a wind power plant, in particular rotor blades and / or nacelles, by means of a crane. The device includes a movable bracket that is movably connected to the crane in the direction of the longitudinal axis of the crane. The device also includes at least one tensioning device, preferably a cable, which is connected to a movable support at its first end, and can be connected to a component of the wind power plant at its second end, so as to The position of stable components during operation and assembly. The invention also relates to a corresponding method in which the position of the member to be lifted is stabilized by means of at least one tensioning device during operation and assembly or disassembly. In this case, the at least one tensioning device is moved in the direction of the longitudinal axis of the crane during the vertical lifting movement of the component...
