Description
ANORDNING OG METODE VED VEDLIKEHOLD AV EN VINDTURBIN DEVICE AND METHOD FOR MAINTENANCE OF A WIND TURBINE
Denne oppfinnelsen angår en anordning og metode til bruk ved vedlikehold av landbasert og flytende vindturbin konstruksjoner. This invention relates to a device and method for use in the maintenance of land-based and floating wind turbine structures.
Nærmere bestemt dreier det seg om en arbeidsplattform som ved hjelp av wire, vogner og wincher bringes i posisjon på vertikal søylestruktur for å kunne utføre bemannet vedlikehold på vindpropellen og strukturer. More specifically, it concerns a work platform which, with the help of wire, trolleys and winches, is brought into position on a vertical column structure in order to be able to carry out manned maintenance on the wind propeller and structures.
Store vindturbiner har i dag mekanisk og elektrisk utstyr for elektrisk energi produksjon plassert 100- 200 meter over bakkenivå eller havnivå. Dette gir store utfordringer nå det må utføres nødvendig vedlikehold, spesielt gjelder dette vedlikehold på propellen. På landbasert vindturbiner benyttes i dag store lifter for vedlikehold på propellvinger. Et alternativ til lifter er å slippe ned mannskaper langs propell vingen, hengende i tau eller wire. Large wind turbines today have mechanical and electrical equipment for electrical energy production located 100-200 meters above ground level or sea level. This presents major challenges now that the necessary maintenance must be carried out, this particularly applies to maintenance on the propeller. On land-based wind turbines, large lifts are currently used for maintenance on propeller blades. An alternative to elevators is to drop crews along the propeller wing, hanging from ropes or wires.
For offshore vindturbiner er utfordringene mye mer utfordrende, spesielt på flytende vindturbiner der det må benyttes utstyr som tar hensyn til bølgebevegelser. For offshore wind turbines, the challenges are much more challenging, especially on floating wind turbines where equipment that takes wave movements into account must be used.
Utgifter til planlagte og uforutsette vedlikehold utgjør den største og mest usikre delen av driftskostnadene. Expenses for planned and unforeseen maintenance make up the largest and most uncertain part of operating costs.
Det er derfor et stort behov for å komme frem til sikre og kostnadseffektive løsninger for vedlikehold, spesielt når det skal utføres «tyngre» vedlikeholdsoppgaver som krever at personer må benyttes til å utføre arbeidet. I slike tilfeller stilles det strenge krav til sikkert utstyr. There is therefore a great need to come up with safe and cost-effective solutions for maintenance, especially when "heavier" maintenance tasks are to be carried out that require people to be used to carry out the work. In such cases, there are strict requirements for safe equipment.
Foreliggende oppfinnelse har til hensikt å løse utfordringene med dagens utstyr for «tyngre» vedlikehold av vindturbiner, eller i det minste redusere en eller flere av utfordringene. The present invention aims to solve the challenges with current equipment for "heavier" maintenance of wind turbines, or at least reduce one or more of the challenges.
Oppfinnelsen vedrører en anordning og metode som angitt i de vedføyde kravene. The invention relates to a device and method as stated in the appended claims.
I henhold til oppfinnelsen oppnås dette ved at en klatrevogn bestående av to halvdeler som settes rund vertikal hovedsøyle på vindturbinen. Klatrevognen er forsynt med gummibelter eller hjul som klemmes radielt inn mot senterlinjen på vindturbinens søylefundaments lengdeakse. Vognen beveges langs søylen med hjul eller belter som er tilordnet drivverk med hydraulisk eller elektrisk energikilde, styret med fjernbetjening og energitilførsel, enten gjennom kabel eller batteri på klatrevognen. According to the invention, this is achieved by a climbing carriage consisting of two halves that is placed around the main vertical column of the wind turbine. The climbing trolley is equipped with rubber belts or wheels which are clamped radially towards the center line of the longitudinal axis of the wind turbine's column foundation. The trolley is moved along the column with wheels or belts which are assigned to a drive unit with a hydraulic or electric energy source, the steering wheel with remote control and energy supply, either through a cable or a battery on the climbing trolley.
I første fase av opprigging av vedlikeholds utstyret kjøres klatrevognen opp til topp av vertikal søyle og tar med seg to eller flere wire som festes til topp av vertikal søyle med kroker eller « klakker» som presses radielt mot vertikal søyle. Når denne sekvensen er fullført kobles det, rundt vertikal søyle nede, på en vogn bestående av to halvdeler tilordnet en arbeideplattform. Denne vognen er tilordnet radielt forskyv bare gummihjul trekkes så oppover vertikal søyle ved hjelp av wirene som er trukket opp tidligere . Trekkraften tilveiebringes av wincher montert på vognen og med energitilførsel gjennomkabel eller fra batteri. In the first phase of setting up the maintenance equipment, the climbing trolley is driven up to the top of the vertical column and takes with it two or more wires that are attached to the top of the vertical column with hooks or "heels" that are pressed radially against the vertical column. When this sequence is completed, it is connected, around the vertical column below, to a carriage consisting of two halves assigned to a work platform. This carriage is assigned radial displacement only rubber wheels are then pulled up the vertical column with the help of the wires that were pulled up earlier. Traction power is provided by winches mounted on the carriage and with energy supply through cable or from a battery.
Vognen med påmontert arbeidsplattform kan nå kjøres i ønsket posisjon for vedlikeholdsarbeider på for eksempel vindturbin blader. The trolley with an attached work platform can now be driven in the desired position for maintenance work on, for example, wind turbine blades.
Når vedlikeholdsoppgavene er sluttført demonteres utstyret ved at vogn med arbeids plattformen senkes ned og demonteres. Deretter kobles klatrevogne fra i toppen og kjøres med sammen med wire. When the maintenance tasks have been completed, the equipment is dismantled by lowering the trolley with the work platform and dismantling it. Climbing carts are then disconnected at the top and driven along with a wire.
Oppfinnelsen skal nå forklares nærmere med henvisning til figurer der The invention will now be explained in more detail with reference to figures therein

Til halvdelene og konsentrisk og radielt inn mot hoved aksen 15 er det anordnet et antall belter 16 som drives av elektrisk eller hydraulisk drivanordning av kjent utførelse. When the climbing cart 5 is securely anchored with hooks 11, it is connected below and to the wires 7 on a cart 6 with work platform 10 which is pulled up to the desired position by means of winch 9 connected to wire 7. The climbing cart 5 is assembled from two halves 12 and 13 which are screwed together with bolt connections 14.

The belts 16 are pushed radially 18 towards the center axis 15 of the column 4, so that the belts always lie with the necessary clamping force against the column 4 when the diameter of the column 4 varies.
Radiell klemkraft på beltene 16 tilveiebringes av en mekanisk eller elektrisk anordning 17 av kjent utførelse. Klatrevognen 5 er forsynt med forankringskroker 11 for forankring mot «nacellen» 2. I fig 8 er vist alternativ festeanordning med «klakker» 30 som presses mot vertikalsøyle 4 ved hjelp av armer 33 aktivert av elektrisk eller hydraulisk aktivator 34. Radial clamping force on the belts 16 is provided by a mechanical or electrical device 17 of known design. The climbing trolley 5 is provided with anchoring hooks 11 for anchoring to the "nacelle" 2. Fig. 8 shows an alternative fastening device with "heels" 30 which are pressed against the vertical column 4 by means of arms 33 activated by electric or hydraulic activator 34.
