Opfindelsen angår et stativ til håndtering af vingetipenden af en vindmølleende med en vingerodende og en vingetipende, hvilket stativ omfatter understøtningsorganer til understøtning af vingetipenden i lodret retning.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a stand for handling the blade tip of a wind turbine end with a wing tip and a blade tip, which includes support means for supporting the blade tip in a vertical direction.
Moderne vindmøllevinger kan være op til 60 m lange og kræver derfor særlige indret-5 ninger til transport, opbevaring og håndtering i perioden, fra de forlader støbemaskinen til de hænger på vindmøllen.Modern wind turbine blades can be up to 60 m long and therefore require special devices for transport, storage and handling during the period, from leaving the casting machine until they hang on the wind turbine.
Efter støbningen kræver vindmøllevingen en efterbehandling, f.eks. afslibning af grater mm. Til dette formål kan der anvendes særlige vognsæt, som understøtter vingerodenden og vingetipenden, og som vingen kan rotere på omkring sin længdeakse, så at den er 10 tilgængelig hele vejen rundt. Der kendes således en vingetipvogn, der omfatter en ramme med kørehjul og en drejeligt om en horisontal akse på rammen anbragt støtte- og fastgørelsesindretning til understøtning og fastgørelse af vingetipenden. En sådan vingetipvogn er forholdsvis kompliceret og dyr i forbindelse med opbevaring af vingen gennem længere tid og transport af vingen over større afstande fra f.eks. producenten til 15 kunden. En yderligere ulempe er, at vingetipvognen fylder meget i forbindelse med transport, og dette er især uhensigtsmæssigt, fordi det i visse tilfælde kan betyde, at en lastbil, der transporterer en eller flere vinger, der hviler på en sådan vingetipvogn, får en så stor samlet højde, at den ikke kan passere under nogle broer og derfor må køre en omvej.After casting, the wind turbine blade requires finishing, e.g. grinding of burrs etc. For this purpose, special carriage kits can be used which support the wing tip and wing tip, and which the wing can rotate about its longitudinal axis so that it is accessible all the way around. Thus, there is known a wing tipper comprising a frame with drive wheels and a rotatable about a horizontal axis on the frame supporting and fastening means for supporting and fastening the wing tip. Such a wingtip trolley is relatively complicated and expensive in connection with the storage of the blade over a longer period of time and transport of the wing over longer distances, e.g. the manufacturer to the 15 customer. A further disadvantage is that the wingtip trolley is very crowded in transport, and this is particularly inconvenient because in some cases it can mean that a truck carrying one or more blades resting on such a wingtip trolley gets such a large overall height, that it cannot pass under some bridges and therefore must run a detour.
20 Der kendes også indretninger til opbevaring og anvendelse i forbindelse med transport over større afstande, hvor et stativ til håndtering af vingetipenden omfatter en ramme, der kan anbringes på et underlag og organer til understøtning af vingetipenden i lodret retning. Disse indretninger er særligt udformet med henblik på transport på lastbil og opbevaring, men er ikke så velegnet til håndtering af vingen, når denne f.eks. skal 25 bringes fra produktionshallen til en opbevaringsplads, hvor vingen opbevares, inden den skal transporteres til en kunde.20 Devices for storage and use are also known in connection with transport over long distances, where a rack for handling the wing tip comprises a frame which can be mounted on a support and means for supporting the wing tip in a vertical direction. These devices are specially designed for truck transport and storage, but are not well suited for handling the wing when, for example, 25 must be brought from the production hall to a storage facility where the blade is stored before transporting it to a customer.
DK 174614 B1 2DK 174614 B1 2
Vindmøllevingens rodende omfatter sædvanligvis en rund flange med boltehuller med henblik på fastgørelse af vingen til møllenavet. Disse boltehuller kan udnyttes til fastgørelse af vingerodenden til et stativ, ved hjælp af hvilket vingerodenden kan stilles stabilt og sikkert på den ende af lastbilanhængeren, der er nærmest førehuset. Vinge-5 tipenden derimod er ikke forsynet med midler eller organer til fastgørelse på noget stativ, og et stativ til understøtning og fastholdelse af vingetipenden må derfor udformes således, at særlige organer kan gå i indgreb med vingetipendens særlige geometriske form, der i tværsnit nærmest er oval.The root of the wind turbine blade usually includes a round flange with bolt holes for attaching the blade to the mill hub. These bolt holes can be utilized for attaching the wing end to a stand, by means of which the wing end can be fixedly and securely on the end of the truck trailer closest to the cab. The blade tip tip, on the other hand, is not provided with means or means for attaching to any rack, and a rack for supporting and retaining the blade tip must therefore be designed so that special means can engage the particular geometric shape of the blade tip which is almost cross-sectional. oval.
I denne forbindelse er det vigtigt at udforme disse organer, så at de ikke beskadiger 10 vingen under transport, hvor der kan opstå slagpåvirkninger, hvis lastbilen kører over ujævnheder.In this connection, it is important to design these bodies so that they do not damage the blade during transport, where impact can occur if the truck is driving over bumps.
Formålet med opfindelsen er at anvise et nyt og praktisk stativ til håndtering af vingetipenden af en vindmøllevinge i forbindelse med opbevaring og transport af denne, og hvor de føromtalte ulemper undgås.The object of the invention is to provide a new and practical stand for handling the blade tip of a wind turbine blade in connection with its storage and transport and where the aforementioned disadvantages are avoided.
15 Formålet er ifølge opfindelsen opnået ved, at stativet er sammensat af en overdel og et understel, der kan adskilles, idet overdelen omfatter organerne til understøtning af vingetipenden i lodret retning, og understellet omfatter kørehjul. Herved opnås, at vingen, mens vingetipenden den hviler på understøtningsorganeme, og mens overdelen og understellet er samlet, let kan flyttes eller transporteres over korte afstande, idet 20 vingetipenden, mens den ruller på kørehjulene, kan trækkes efter vingerodsenden, der bevæges ved hjælp af en kran eller vogn. Når vingen skal transporteres over større afstande, kan stativets overdel, hvorpå vingetipenden hviler, ganske enkelt løftes af understellet og anbringes på en lastbil, idet man herved reducerer den samlede højde af lastbill, stativ og vinge. Understellet kan så anvendes sammen med en anden overdel, 25 og på denne måde kan der spares komponenter og plads.The object according to the invention is achieved in that the frame is composed of a separable upper and lower frame, the upper part comprising the means for supporting the wing tip in a vertical direction and the base comprising driving wheels. This provides that the wing, while the wing tip it rests on the support members, and while the upper and chassis are assembled, can be easily moved or transported over short distances, the wing tip, while rolling on the wheels, can be drawn by the wing root end which is moved by means of a crane or wagon. When the wing is to be transported over greater distances, the top of the stand on which the wing tip rests can simply be lifted off the chassis and placed on a truck, thereby reducing the overall height of the truck, stand and wing. The chassis can then be used with another top 25, thus saving components and space.

Ifølge opfindelsen kan stativet omfatte fikseringsorganer til fastholdelse af vingetipen-den, mens denne understøttes af understøtningsorganerne, mod drejning omkring en lodret akse i forhold til stativet. Herved opnås en bedre styring af stativet ved transport med påmonteret understel, fordi stativet vil følge vingens drejning omkring lodret akse.According to the invention, the frame may comprise fixing means for retaining the blade tip while supported by the supporting means against rotation about a vertical axis relative to the frame. This provides better control of the stand when transported with the mounted frame, because the stand will follow the rotation of the blade about the vertical axis.
5 Ifølge en foretrukken udførelsesform er fikseringsorganeme monteret på understellet.According to a preferred embodiment, the fixing means are mounted on the chassis.
Ved transport over større afstande anbringes overdelen med vingetipenden på lastbilanhængeren og en fiksering mod drejning omkring lodret akse er derfor ikke nødvendig. Overdelen har således kun de komponenter, der er nødvendige i forbindelse med denne transportform, hvilket gør overdelen lettere og billigere. Dette er især fordelagtigt, når 10 man ønsker at anvende et og samme understel til flere overdele.When transporting over long distances, the upper part with the wing tip is placed on the truck trailer and a fixation against rotation about the vertical axis is therefore not necessary. Thus, the top has only the components needed for this mode of transport, which makes the top easier and cheaper. This is especially advantageous when you want to use the same frame for several tops.
Fikseringsorganeme kan udgøres af klembakker eller tryksko, der er indstillelige i vandret retning, så at de kan klemme mod hver sin side af vingetipenden.The fixing means can be constituted by clamping trays or pressure shoes which are adjustable in the horizontal direction so that they can clamp against each side of the wing tip.
Ifølge en udførelsesform omfatter understellet en ramme, og klembakkeme er drejeligt hængslede ved enden af hver sin arm, der ved den modsatte ende er drejeligt hængslet 15 til understellets ramme, idet der mellem hver arm og rammen forløber et teleskopagtigt indstilleligt ben, så at klembakkemes position i vandret retning kan indstilles ved hjælp af de indstillelige ben. Dette er en særlig enkel og sikker udførelsesform.According to one embodiment, the chassis comprises a frame and the clamping trays are pivotally hinged at the end of each arm, at the opposite end pivotally hinged 15 to the chassis frame, with a telescopic-like adjustable leg extending between each arm and the frame so that the position of the clamping trays in the horizontal direction can be adjusted using the adjustable legs. This is a particularly simple and secure embodiment.
Understellets ramme kan i det væsentlige være rektangulær, set oppefra, og der kan være tilvejebragt et par klemplader ved to modstående sider. Herved opnås en særlig 20 sikker fiksering af vingetipenden.The frame of the chassis may be substantially rectangular, seen from above, and a pair of clamping plates may be provided at two opposite sides. This provides a particularly secure fixation of the blade tip.
Ifølge en udførelsesform kan overdelen omfatte en vandret ramme med to lodrette stolper, og understøtningsorganeme udgøres af en båndformet strop, der er ophængt mellem de to lodrette stolper. Herved opnås, at vingetipenden understøttes i lodret retning på en særlig skånsom måde, idet slagpåvirkninger, som overdelen udsættes for, 25 ikke overføres direkte, men via stroppen til vingetipendens overflade.According to one embodiment, the upper part may comprise a horizontal frame with two vertical posts, and the supporting members are constituted by a band-shaped strap suspended between the two vertical posts. In this way, the wing tip is supported in a vertical direction in a particularly gentle manner, in that the impact to which the upper part is exposed is not transmitted directly, but via the strap to the surface of the wing tip.
DK 174614 B1 4 Sådanne slagpåvirkninger kan typisk opstå, når lastbilanhængeren, som vingen transporteres på, kører over ujævnheder. Ligeledes undgås det, at vingen bidrager til anhængerens stivhed, hvilket kunne medføre, at vingen ville blive udsat for kraftige mekaniske påvirkninger i sine understøtningspunkter.DK 174614 B1 4 Such impact impacts can typically occur when the truck trailer on which the wing is being carried travels over bumps. Also, the wing is prevented from contributing to the stiffness of the trailer, which could cause the wing to be subjected to strong mechanical stresses at its support points.
5 En foretrukken udførelsesform er ejendommelig ved, at understellet omfatter en rektangulær ramme samt indvendige bæreplader, og at overdelen omfatter en rektangulær ramme, hvis ydre dimensioner svarer til de indvendige dimensioner af understellets ramme, så at overdelen kan sænkes ned i underdelen og hvile på bæreplademe. Med en sådan udformning kan der opnås en særlig enkel fiksering mellem overdel og understel.A preferred embodiment is characterized in that the chassis comprises a rectangular frame and inner support plates and the upper part comprises a rectangular frame whose outer dimensions correspond to the inner dimensions of the chassis frame, so that the upper part can be lowered into the base and rest on the support plates. . With such a design, a particularly simple fixation between upper and lower frame can be achieved.
10 Opfindelsen angår også et undestel til anvendelse med stativet ifølge opfindelsen, hvilket understel omfatter kørehjul og fikseringsorganer til fastholdelse af vingetipenden.The invention also relates to a chassis for use with the rack of the invention, which chassis comprises driving wheels and fixing means for holding the blade tip.
Opfindelsen angår desuden en overdel til anvendelse med stativet ifølge opfindelsen, hvilken overdel omfatter organer til understøtning af vingetipenden i lodret retning.The invention further relates to an upper for use with the rack according to the invention, which includes means for supporting the wing tip in a vertical direction.
Opfindelsen vil i det følgende blive forklaret nærmere ved hjælp af en foretrukken 15 udførelsesform, der er vist på den vedføjede tegning, hvor fig. 1 viser en overdel til et stativ ifølge opfindelsen, set fra enden, fig. 2 overdelen, set fra siden, fig. 3 overdelen, set oppefra, fig. 4 et understel til et stativ ifølge opfindelsen, set ffa enden, 20 fig. 5 understellet, set fra siden, 5 DK 174614 B1 fig. 6 understellet, set oppefra, fig. 7 hele stativet med overdel og understel i samlet tilstand, set fra enden, fig. 8 hele stativet, set fra siden, fig. 9 hele stativet, set oppefra, 5 fig. 10 et vingerodsstativ til fatholdelse af vingerodenden, set fra enden, fig. 11 samme set oppefra, og fig. 12 samme set fra siden.The invention will now be explained in more detail by way of a preferred embodiment shown in the accompanying drawing, in which: FIG. 1 is an end view of an upper part of a rack according to the invention; FIG. 2 is a side view of the upper part; FIG. 3, the top view, FIG. 4 shows a frame for a rack according to the invention, seen from the end; FIG. 5 side view, 5 DK 174614 B1 fig. 6, the top view, fig. 7 shows the entire frame with upper and lower frame in overall condition, seen from the end, fig. 8 is a side view of the entire frame; FIG. 9 shows the entire frame, top view; FIG.

Den i fig. 1-3 viste overdel 3 til stativet ifølge opfindelsen omfatter i det væsentlige en vandret rektangulær profilramme omfattende to korte profildele 24 og to lange profildele 10 25. To lodrette stolper 9 rager op fra midten af hver af de to korte profildele 24 og er afstivet ved hjælp af skråstivere 23, 31. Skråstiveme 31 forbinder stolperne 9 med en ikke-synlig central profildel, der forløber mellem de to korte profildele 24. Et understøtningsorgan i form af en løftestrop 2 er ophængt mellem de to stolper 9 ved hjælp af huller 20 og ikke-viste splitter. Hver stolpe omfatter fire huller, så at den lodrette posi-15 tion af løftestroppen kan indstilles. En i stroppens 2 længderetning og tværretning forskydelig, gummibelagt bæreskinne 18 tjener til optagelse af vingetipendens nedadven-dende kantdel. Hver stolpe 9 er forsynet med nedre øjeorganer 22 med henblik på fastgørelse af overdelen til en lastbil og to øvre øjeorganer 21, ved hjælp af hvilke overdelen 3 og dermed vingen kan løftes ved hjælp af en kran. Hver stolpe 9 er desuden 20 ved sin øvre ende forsynet med et hul 29 til fastgørelse af en sikkerhedsstrop 17 (se fig.The FIG. 1-3 of the rack according to the invention comprise substantially a horizontal rectangular profile frame comprising two short profile parts 24 and two long profile parts 10 25. Two vertical posts 9 extend from the center of each of the two short profile parts 24 and are supported by by means of inclined struts 23, 31. The inclined struts 31 connect the posts 9 to a non-visible central profile part extending between the two short profile parts 24. A support member in the form of a lifting strap 2 is suspended between the two posts 9 by means of holes 20 and not shown splits. Each post comprises four holes so that the vertical position of the lifting strap can be adjusted. A rubberized slide 18, slidable in the longitudinal direction and transverse direction of the strap 2, serves to receive the downwardly extending edge portion of the wing tip. Each post 9 is provided with lower eye means 22 for attaching the upper part to a truck and two upper eye means 21, by means of which the upper part 3 and thus the wing can be lifted by means of a crane. In addition, each post 9 is provided at its upper end with a hole 29 for securing a safety strap 17 (see FIG.
7), hvis funktion vil blive forklaret senere. Endelig er hver stolpe 9 forsynet med en drejeligt hængslet, gummibelagt beskyttelsesplade 19 for at beskytte vingens overflade mod stolpernes 9 skarpe kanter.7), whose function will be explained later. Finally, each post 9 is provided with a pivotally hinged, rubberized protective plate 19 to protect the surface of the blade from the sharp edges of posts 9.
DK 174614 B1 6 I fig.4-6 ses understellet 4, som er bygget op omkring en rektangulær profilramme med to korte profildele 26 og to lange profildele 27. Hvert af rammens hjørner er forsynet med kørehjul 5, der er drejelige omkring en lodret akse. Understellet 4 omfatter to par klemplader 6, der er drejeligt hængslet til den frie ende af hver sin arm 7, som igen er 5 drejeligt hængslet til profilrammens lange profildel 27. Mellem hver arms 7 frie ende og rammens lange profildel 27 forløber et teleskopagtigt indstilleligt ben 8. Ved at indstille længden af dette ben 8 kan vinklen mellem profildelen 27 og armen 7 indstilles og herved afstanden mellem klemplademe 6. De indstillelige ben er i den viste udførelsesform hver især udformet som to gevindstænger, der er skruet ind i hver sin ende af 10 et rør med indvendigt gevind. Røret er forsynet med et tværgående hul, og ved at dreje et håndsving 30, der er ført gennem dette hul, drejes røret omkring sin længdeakse, hvorved gevindstængeme, der fastholdes mod rotation ved deres modsatte ende, skrues ind eller ud. Herved kan længden af armene 7 indstilles og klempladerne 6 kan således bringes i indgreb med vingetipendens sider 6 med henblik på fastholdelse af vingetipen-15 den.DK 174614 B1 6 Fig. 4-6 shows the chassis 4, which is built around a rectangular profile frame with two short profile parts 26 and two long profile parts 27. Each of the corners of the frame is provided with drive wheels 5 rotatable about a vertical axis. . The chassis 4 comprises two pairs of clamping plates 6 pivotally hinged to the free end of each arm 7, which in turn 5 pivotably hinged to the long profile portion 27 of the profile frame. Between a free end of each arm 7 and the long profile portion 27 of the frame extends a telescopically adjustable leg. 8. By adjusting the length of this leg 8, the angle between the profile part 27 and the arm 7 can be adjusted and thereby the distance between the clamping plates 6. The adjustable legs are each shown in the embodiment shown as two threaded rods screwed into each end of the 10 an inner threaded tube. The tube is provided with a transverse hole, and by turning a crank 30 passed through this hole, the tube is rotated about its longitudinal axis, thereby screwing in or out the threaded rods which are held against rotation at their opposite end. In this way, the length of the arms 7 can be adjusted and the clamping plates 6 can thus be engaged with the sides of the wing tip 6 in order to maintain the wing tip 15.
I fig. 5 ses understellet fra en side, og det ses tydeligt, at hver af profilrammens lange sider 27 er forsynet med et sæt klemorganer, hvorved der kan sikres en særlig effektiv fastholdelse af vingetipenden i forhold til understellet. 1 fig. 7-9 ses stativet ifølge opfindelsen klar til brug, idet en vingetipende 28, hvis 20 tværsnit er antydet med stiplet linie i fig. 7, er understøttet af overdelens løftestrop 2 og ved indstilling af armene 7 kan fastholdes ved hjælp af understellets klemplader 6.1 fig.In FIG. 5, the chassis is viewed from one side and it is clearly seen that each of the long sides 27 of the profile frame is provided with a set of clamping means, thereby ensuring a particularly effective holding of the wing tip relative to the chassis. 1 FIG. 7-9, the frame according to the invention is shown ready for use, with a wing tip 28, the cross section of which 20 is indicated by a dotted line in FIG. 7, is supported by the lifting strap 2 of the upper part and when adjusting the arms 7 can be held by means of the clamping plates 6.1.
7 er der også med stiplet linie antydet en sikkerhedsstrop 17, der forløber mellem overdelens to stolper 9 hen over vingetipenden 28. Under transport på en lastbil ved hjælp af overdelen 3 fastholdes vingen ikke af klemorganeme 6. Hvis lastbilen kører over 25 ujævnheder, vil vingen kunne bevæge sig opad, og for at begrænse denne bevægelse i opadgående retning anvendes sikkerhedsstroppen 17.7, a dashed line 17 also indicates a safety strap 17 extending between the two posts 9 of the upper body over the wing tip 28. During transport on a truck by means of the upper 3, the wing is not held by the clamping means 6. If the truck runs over 25 bumps, the wing will could move upwards, and to limit this upward movement, the safety strap 17 is used.

Som det især kan ses i fig. 9, er overdelens 3 rektangulære ramme anbragt inden i understellets rektangulære ramme i stativets samlede tilstand.As can be seen particularly in FIG. 9, the rectangular frame of the upper part 3 is disposed within the rectangular frame of the frame in the overall state of the frame.
I fig. 10-12 ses et stativ til understøtning og fastholdelse af vingerodenden. Vingeroden-den har en cirkulær flange med boltehuller, hvilket er indikeret med cirklen 12 i fig. 6.In FIG. 10-12 shows a stand for supporting and holding the wing tip. The wing root has a circular flange with bolt holes, which is indicated by the circle 12 in FIG. 6th
5 Vingerodsstativet omfatter tre lodret forløbende profilorganer 13, 14 med huller, så at de kan fastgøres til vingrodenden ved hjælp af bolte, der føres gennem hullerne og skrues fast i tre af vingerodflangens boltehuller. Vingerodsstativet omfatter fødder i form af U-profiler 15 og kan løftes ved hjælp af en gaffeltruck.The wing root frame comprises three vertically extending profile members 13, 14 with holes so that they can be secured to the wing root end by bolts passing through the holes and screwed into three of the wing root flange bolt holes.
