Fra DK/EP 2084098 T3, kendes en fremgangsmåde og et vindmøllevingeiøf-15 tesystem omfattende en løfteindretning med en ramme der er konstrueret til at kunne forbindes med en vindmøllevinge og en kranarm med et spil, og i det mindste et styrekabel som forløber imellem wirehjul placeret på kranens arm og til et spilarrangement på rammen, til at styre vingens orientering til at være i et i det væsentlige vandret plan når den er løftet fra jorden, og hvor spilarrangementet er 2 0 placeret på løfteindretningen.From DK / EP 2084098 T3, there is known a method and a wind turbine blade lifting system comprising a lifting device with a frame designed to be connected to a wind turbine blade and a crane arm with a winch, and at least a control cable extending between wire wheels on the crane's arm and to a player arrangement on the frame, to control the orientation of the wing to be in a substantially horizontal plane when lifted from the ground and where the player arrangement is located on the lifting device.
Det kendte vindmølleløftesystem omfatter, at styrekablet/styrekabler er forbundet med spil placeret på løfteindretningen, hvilket medfører en vægtforøgelse af løfteindretningen, og tillige et styringsproblem, eftersom det vil være nødvendigt 2 5 at kunne fjernstyre spillene, idet vindmøilevingeløftesystemet ikke er forudsat be mandet. Et yderligere og mere udtalt problem er, at styrekablet kun i en vis udstrækning sikrer møllevingens retningsstabilitet under løft og håndtering af en vindmøiievinge i et i det væsentlige vandret plan, idet alene rammens vægt i kombination med vægten af vindmøllevingen er med til at sikre vindmøllevingen i 3 0 rammen imod vindpåvirkning under montering af vingen på møllens nav. En form for kontrol er søgt etableret ved at forsyne spillet på løfteindretningens ramme med en fireblok, der etablerer et modhold i forhold tii spillets forskydning af styrekablet.The known wind turbine lift system comprises that the control cable (s) are connected to winches located on the lifting device, which causes an increase in weight of the lifting device, and also a control problem, since it will be necessary to be able to remotely control the winches, since the wind turbine lifting system is not required. A further and more pronounced problem is that the control cable ensures to a certain extent only the directional stability of the wind turbine during lifting and handling of a wind turbine vane in a substantially horizontal plane, since only the weight of the frame in combination with the weight of the wind turbine blade helps to secure the wind turbine blade. 3 0 the frame against wind influence during mounting of the blade on the mill hub. A form of control is sought to be established by providing the game on the frame of the lifting device with a four-block which establishes a resistance against the game's displacement of the control cable.

Det er ved opfindelsen indset at dette er mulig ved anvendelse af en løfteramme til anvendelse ved løft og montage af vinger på vindmøller af den art der omfatter en ramme med en første og en anden ende, beregnet til at kunne forbindes med en vindmøilevinge, samt et spii på en kran med kranarm for bæring af 30 vingens vægt, hvor rammen er indrettet til at løfte og fasthoide en i denne anbragt vindmøilevinge i et i det væsentlige vandret pian, alternativt at løfterammen er indrettet til at løfte øg fastholde en i denne anbragt vindmøilevinge i tilnærmelsesvist enhver tænkelig orientering forskellig fra et i det væsentlige vandret plan og positi- P10097DK00\PA 2012 00751 DK 177672 B1 3 on, hængende i kranens hovedwire, og hvor kranen omfatter i det mindste to sekundære spiisystemer med sekundære wirer, og hvor kranarmen omfatter et antai dermed samvirkende sekundære wirehjui, lokaliseret på den imod hovedwiren fil-vendende side af kranarmen, alternativt på kranarmens sider, kendetegnet ved, at 5 iøfterammen på den imod kranarmen tilvendende side og nær ved henholdsvis den første ende og den anden ende af rammen omfatter i det mindste et første og et andet wirehjui til forbindelse med wirer hidrørende fra de uafhængige sekundære spiisystemer, hvor wiren imellem de sekundære uafhængige spilsystemer forløber i en trekant imellem kranens sekundære wirehjui, via det første og andet wire-10 hjul på løfterammen videre ti! uafhængige fastgørelsespunkter ved foden af kran-armen.It is recognized by the invention that this is possible by using a lifting frame for use in lifting and mounting blades on wind turbines of the type comprising a frame having a first and a second end, intended to be connected to a wind turbine blade, and a spii on a crane with a crane arm for carrying the weight of the blade, the frame being adapted to lift and fasten a windmill wing disposed therein in a substantially horizontal pane, or alternatively that the lifting frame is adapted to lift an eye to hold a windmill wing arranged in this in virtually every conceivable orientation different from a substantially horizontal plane and position, suspended in the main wire of the crane, and wherein the crane comprises at least two secondary splicing systems with secondary wires, and wherein the crane arm comprises an antiparticularly cooperating secondary wire wheel located on the side of the crane arm facing the main wire, alternatively on the crane while sides, characterized in that the lift frame on the side facing the crane arm and near the first end and the second end of the frame, respectively, comprises at least a first and a second wire sheave for connection with wires originating from the independent secondary splicing systems, wherein The wire between the secondary independent gaming systems runs in a triangle between the secondary wire wheel of the crane, via the first and second wire-10 wheels on the lift frame further ten! independent attachment points at the foot of the crane arm.
Ved således at udnytte kranens sekundære spiisystemer, hvis wirer føres via wirehjui på kranarmen og endvidere forbinde disse med henholdsvis det første og 15 andet wirehjui på rammen, hvorefter de forankres ved foden af kranarmen, i kombination med kranens hoved løffewire, der bærer såvel rammen som vindmøllevingen anbragt deri, opnås en dobbelt triangulær styring af rammen og dermed vindmøllevingens orientering, som medfører en forøget stabilitet i forhold ti! den kendte teknik, idet kranens sekundære styrewirer i kombination med kranens ho-2 0 vedløftewire er i stand til at etablere en forøget vandret orienteret kraft i retning mod kranarmen i to angrebspunkter på løfterammen givet ved det første øg det andet wirehjui på denne, ved at trække i henholdsvis i styrewirerne og i kranens hovedløftewire, hvorved den vandrette kraft hidrørende fra tyngden af ramme og vinge forøges ved det nedadrettede træk, der kan genereres ved den triangulære 2 5 føring af styrewirerne. Den dermed forøgede vandret orienterede kraftpåvirkning af rammen, medfører en stærkt forøget stabilitet af vindmøllevingen, øg dermed en højere grad af sikkerhed under håndtering og montage af vindmøllevinger anbragt i en løfteramme indrettet ifølge opfindelsen. Eftersom de kendte styringsindretninger ikke frembyder mulighed for at tilvejebringe en dobbelt triangulær styring med 30 mulighed for generering af en nedadrettet kraftpåvirkning af iøfterammen, vi! anvendelse af Iøfterammen ifølge opfindelsen medføre en betydelig større stabilitet af vindmøllevingen under montering, under større vindpåvirkning, hvor styreanordningerne ifølge den kendte teknik ikke er tilstrækkelige.Thus, by utilizing the secondary splicing systems of the crane, the wires of which are routed via wire hoi on the crane arm and further connecting them with the first and second wire hoi on the frame respectively, after which they are anchored at the foot of the crane arm, in combination with the main running wire of the crane carrying both the frame and The wind turbine blade disposed therein achieves a double triangular control of the frame and thus the orientation of the wind turbine blade, which results in increased stability relative to ten! The prior art, wherein the crane's secondary guide wires, in combination with the crane's hoist lift wire, are capable of establishing an increased horizontally oriented force toward the crane arm at two points of attack on the lifting frame given the first increase of the second wire hoist thereof. pull in the guide ropes and in the main lifting wire respectively, thereby increasing the horizontal force resulting from the weight of the frame and wing by the downward pull which can be generated by the triangular guide of the guide ropes. The thus increased horizontally oriented force influence of the frame results in a greatly increased stability of the wind turbine blade, thus increasing a higher degree of safety during handling and assembly of wind turbine blades arranged in a lift frame arranged according to the invention. Since the known control devices do not offer the possibility of providing a double triangular control with the possibility of generating a downward force influence of the lift frame, we! The use of the lift frame according to the invention results in a considerably greater stability of the wind turbine blade during mounting, under a higher wind load, where the control devices according to the prior art are not sufficient.

25 I fig. 2, hvor løfterammen 11 antages at være hævet til montagepositionen for en ikke vist vindmøllevinge lejret i løfterammen 11, vil det være muligt at styre og stabilisere løfterammen 11 bærende en møllevinge, ved at stramme de sekundære wirer 12, 14, ved aktivering af de sekundære spil 9, 13, uden at slække kranens 30 hovedløftewire 6, hvilket vil medføre en vandret orientere kraftpåvirkning af løfterammen 11 i retning mod kranarmen 4, idet wiren imellem det første og andet wirehjul 26, 28 på løfterammen 11, vil blive forkortet.In FIG. 2, where the lift frame 11 is assumed to be raised to the mounting position of a wind turbine blade (not shown) mounted in the lift frame 11, it will be possible to control and stabilize the lift frame 11 carrying a turbine blade by tightening the secondary wires 12, 14, by activating the secondary winch 9, 13, without slackening the main lifting wire 6 of the crane 30, which will cause a horizontally oriented force actuation of the lifting frame 11 in the direction of the crane arm 4, as the wire between the first and second wire wheels 26, 28 on the lifting frame 11 will be shortened.
Det vil endvidere være muligt at foretage en vis styring af løfterammens ori-35 entering ved udøvelse af et differentieret træk i de sekundære wirer 12, 14.In addition, it will be possible to make some control of the orientation of the lift frame by exercising a differentiated pull in the secondary wires 12, 14.
