Description
ANORDNING OG METODE VED MONTERING OG DEMONTERING AV VINGER PÅ EN VINDTURBIN Denne oppfinnelsen omhandler en anordning og metode for å kunne montere og demontere propellvinger på en vindturbin uten bruk av mannskap som utfører operasjoner med skrueforbindelser. DEVICE AND METHOD FOR MOUNTING AND DISMANTLING BLADES ON A WIND TURBINE This invention relates to a device and method for being able to mount and dismantle propeller blades on a wind turbine without the use of crew who carry out operations with screw connections.
Nærmere bestemt dreier det seg om en løsning der vingene heises opp med en spesiell kranløsning og settes inn i navet ved hjelp av et adapter som går i inngrep mot en sokkelløsning eller dokking med «låseklakker» elektrisk eller hydraulisk aktivert. More specifically, it concerns a solution where the wings are lifted up with a special crane solution and inserted into the hub using an adapter that engages with a plinth solution or docking with electrically or hydraulically activated "locking lugs".
Dagens vindturbinløsninger har utviklet seg fra relativt små landbaserte turbiner til at det nå skal bygges store turbiner montert på flytende fundamenter ute på havet. Today's wind turbine solutions have evolved from relatively small land-based turbines to large turbines now being built mounted on floating foundations out at sea.
Det er innlysende at når komponenter skal monteres på flytende fundamenter ute i havet er utfordringer knyttet til montering og demontering for vedlikehold vesentlig mer krevende enn på landbaserte konstruksjoner. It is obvious that when components are to be mounted on floating foundations out at sea, challenges related to assembly and disassembly for maintenance are significantly more demanding than on land-based constructions.
Propellen på en stor flytende vindturbin til havs plasseres ca.150-200 over havoverflaten. Dette setter spesielle krav til heiseutstyr og montering, spesielt når både heisekran og vindturbinfundament er flytende og påvirket av bølgebevegelser og vindforhold. Bruk av mannskap opp i en slik vindturbin er krevende og stiller store utfordringer til HMS og sikkerhet. The propeller of a large floating offshore wind turbine is placed approx. 150-200 above the sea surface. This places special demands on lifting equipment and assembly, especially when both the lifting crane and the wind turbine foundation are floating and affected by wave movements and wind conditions. Using crew up in such a wind turbine is demanding and poses major challenges to HSE and safety.
Det er et stort behov i vindturbinbransjen for å komme opp med nye løsninger som løser nye utfordringer med tungt vedlikehold av store flytende vindturbiner. There is a great need in the wind turbine industry to come up with new solutions that solve new challenges with heavy maintenance of large floating wind turbines.
Med foreliggende oppfinnelse har en kommet frem til en løsning som gjør det mulig å montere og demontere vingene på en vindturbin uten bruk av mannskap i toppen av vindturbinen. Oppfinnelsen gjør det også mulig å montere og demontere vindturbinvinger i vanskelige værforhold. With the present invention, a solution has been arrived at which makes it possible to assemble and disassemble the blades of a wind turbine without the use of crew at the top of the wind turbine. The invention also makes it possible to assemble and disassemble wind turbine blades in difficult weather conditions.
I henhold til oppfinnelsen er det tilveiebrakt en monteringsløsning der en spesialkran med klatreanordninger fester seg til vertikal søylen på vindturbinen og ved hjelp av klatreanordningen klatrer til topps av vindturbinen. According to the invention, a mounting solution has been provided where a special crane with climbing devices is attached to the vertical column of the wind turbine and with the help of the climbing device climbs to the top of the wind turbine.
Klatreanordningen er forsynt med en kranbom som ved hjelp av hydrauliske sylindere kan bringes i riktig posisjon for oppheising av vinger med bruk av wire og vinsjer. Navet som vingene er festet til er utført med et spesielt dokkingsystem, slik at vingene med adapter kan settes inn i og låses fast med låsesystem bestående av radielle «låseklakker» som går i inngrep mot adapteret på vingene. The climbing device is equipped with a crane boom which, with the help of hydraulic cylinders, can be brought into the correct position for lifting the wings using wire and winches. The hub to which the wings are attached is made with a special docking system, so that the wings with adapter can be inserted into and locked with a locking system consisting of radial "lock lugs" that engage the adapter on the wings.
Navet er også forsynt med rotasjonsanordning for hver vinge, slik at vingene kan settes i ønsket vinkel om lengdeaksen for å optimalisere virkningsgrad i forhold til vindhastighet. The hub is also equipped with a rotation device for each wing, so that the wings can be set at the desired angle around the longitudinal axis to optimize efficiency in relation to wind speed.
Oppfinnelsen skal nå forklares nærmere med henvisning til etterfølgende figurer. The invention will now be explained in more detail with reference to subsequent figures.

På figurene angir henvisningstallet 1 til en flytende vindturbin med søyle 2 og flyteelement 3 forankret med forankringer 4, flytende på havoverflaten 5. In the figures, reference number 1 denotes a floating wind turbine with column 2 and floating element 3 anchored with anchors 4, floating on the sea surface 5.
Til søylen 2 er det anordnet klatreelementer 6 og 7 som ved hjelp av forankringer til søylen 2 kan forskyves innbyrdes med bevegelser 8 og 9. På toppen av klatreelement 8 er påmontert adapter 10, kranbom 11 forbundet med ledd 12 og aktivert av sylindere 13. Wire 14 forbundet til winch anordning 15 og adapter 17 for oppheising av vingen 16. Navet 18 hvor vingene 16 er forbundet til er forbundet til selve vindturbinhuset 19 og roterer om hovedaksen 20. Vindturbinens maskineri med generator og apparatanlegg er plassert i vinturbinhuset 19 som er roterbart om søylen 2 sin hovedakse 23. Climbing elements 6 and 7 are arranged for column 2, which can be moved relative to each other by means of anchors to column 2 with movements 8 and 9. On top of climbing element 8 is mounted adapter 10, crane boom 11 connected to link 12 and activated by cylinders 13. Wire 14 connected to winch device 15 and adapter 17 for hoisting the wing 16. The hub 18 to which the wings 16 are connected is connected to the wind turbine housing 19 itself and rotates about the main axis 20. The wind turbine's machinery with generator and apparatus is located in the wind turbine housing 19 which can be rotated about pillar 2's main axis 23.
Vingene 16 er anordnet med demonterbare koblinger til navet 18, slik at de kan settes på og demonteres uten bruk av manuelle operasjoner. The wings 16 are arranged with demountable connections to the hub 18, so that they can be put on and taken off without the use of manual operations.
Vingen 16 er koblet sammen med et adapter 21 gjennom en flensforbindelse 22. Adapteret 21 med sporet 27 og konisk flate 28 er utformet til å gå i inngrep mot dokking elementet 24, slik at koniske flater 25 og 28 er i inngrep og radielle låseklakker 29 aktiveres i inngrep mot sporet 27, derigjennom låses adapteret 21 til dokking elementet 24. The wing 16 is connected to an adapter 21 through a flange connection 22. The adapter 21 with the groove 27 and conical surface 28 is designed to engage with the docking element 24, so that the conical surfaces 25 and 28 are engaged and radial locking lugs 29 are activated in engagement with the slot 27, through which the adapter 21 is locked to the docking element 24.
Dokking elementet 24 er opplagret i navet 18 gjennom en kulekrans 32 forbundet til navet 18 med platekonstruksjonen 30. Rotasjon av dokking elementet 24 tilveiebringes av en rotasjonsenhet 31 forbundet til kulekransen 32 med fortanninger 33. The docking element 24 is stored in the hub 18 through a ball ring 32 connected to the hub 18 with the plate structure 30. Rotation of the docking element 24 is provided by a rotation unit 31 connected to the ball ring 32 with teeth 33.
Overføring av elektriske signaler til og fra vingene 16 kommer gjennom kabel 35 og blir videreført med kontakter 34 på adapteret 21 til kontakter 36 festet til dokking elementet 24. Transmission of electrical signals to and from the wings 16 comes through cable 35 and is continued with contacts 34 on the adapter 21 to contacts 36 attached to the docking element 24.
