Lifting device for connecting two rotor blade segments of a wind turbine

A lifting assembly for connecting two or more rotor blade segments of a rotor blade, the assembly comprising:

• a 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, and
• means for lifting and/or lowering a rotor blade segment,
• wherein the frame structure comprises a first part of a coupling guide for guiding a coupling of a first rotor blade segment and second rotor blade segment, and wherein said means for supporting and guiding the frame structure in relation to the rotor blade comprises a plurality of contact means, and
• a fixation part having means for fixation of a rotor blade segment, the fixation part further comprising means for connecting the fixation part to the means for lifting and or lowering a rotor blade segment placed in connection with the lifting device.

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 method comprising:

• lifting the lifting device 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, contacting the rotor blade by support means at or near the edge of the rotor blade, which support means are movable in relation to said lifting device,
• lifting and/or lowering the lifting device in relation to the rotor blade while supported and guided by said support means,
• lowering the lifting device down to an end of a first rotor blade segment,
• fixing means for lifting and lowering a second blade segment to a fixation part having means for fixation of a second rotor blade segment,
• lifting the fixation part with the second rotor blade segment up to the end of the first rotor blade segment,
• coupling a first part of a coupling guide placed on the lifting device to a second part of a coupling guide placed on the fixation part, and
• further lifting the fixation part to secure 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.
