Abstract
A lifting device 5 for connecting two rotor blade segments 4A, 4B of a wind turbine at the location of the wind turbine, said lifting device 5 being adapted for being moved in the longitudinal direction of the rotor blade, the lifting device comprising: a frame structure 6, means for supporting and guiding the frame structure in relation to the rotor blade, means for lowering and/or lifting the frame structure in relation to the rotor blade, means 7 for lifting and/or lowering a rotor blade segment 4B.
Claims20
A lifting device for connecting two rotor blade segments of a wind turbine, said lifting device being adapted for being moved in the longitudinal direction of the rotor blade, the lifting device comprising:
- a frame structure,
- means for supporting and guiding the frame structure in relation to the rotor blade,
- means for lowering and/or lifting the frame structure in relation to the rotor blade,
- means for lifting and/or lowering a rotor blade segment.
A method for guiding a connection of two rotor blade segments of a wind turbine, whereby a lifting device comprises a frame structure, means for supporting and guiding the lifting device in relation to said rotor blade, means for lowering and/or lifting the lifting device in relation to the rotor blade and means for lifting and/or lowering a rotor blade segment being placed near said wind turbine essentially at ground or sea level,
- the lifting device is lifted in relation to said wind turbine by means of at least one line, wire or the like connected to said wind turbine or to a crane or the like,
- when the lifting device has reached a suitable level, the rotor blade is contacted by support means at or near the edge of the rotor blade, which support means are movable in relation to said lifting device,
- the lifting device is lifted and/or lowered in relation to the rotor blade while supported and guided by said support means,
- the lifting device is lowered down to an end of a first rotor blade segment,
- means for lifting and lowering a second blade segment is fixed to a fixation part having means for fixation of a second rotor blade segment,
- the fixation part with the second rotor blade segment is lifted up to the end of the first rotor blade segment,
- a first part of a coupling guide placed on the lifting device is coupled to a second part of a coupling guide placed on the fixation part,
- a further lift of the fixation part secures a self-adjustment of the first and second coupling guide parts, whereby the second rotor blade segment is positioned in a correct angle to the first blade segment.
