Abstract

Lifting device comprises a hanging unit (10) which is placed on the blades (12) of a wind power installation. Preferred Features: Two hanging units are placed on two rotor blades of a three-blade wind power installation. A lifting platform is hung on its narrow side with two cables over a hoop. The lifting platform has a recess in the center.

Description

Die Erfindung betrifft eine Hebevorrichtung zur Reparatur und Wartung von Rotorblätter von Windkraftanlagen.The The invention relates to a lifting device for repair and maintenance of rotor blades of wind turbines.

Windkraftanlagen werden erfreulicherweise in zunehmenden Maße eingesetzt. Anders als bei Flugzeugen, deren Propeller am Boden leicht zugänglich repariert werden Können, Können Die Rotoren von Windkraftanlagen nur schwer repariert werden. Weiter müssen von Zeit zu Zeit Zur Prüfung, Kontrolle und Abnahme direkter Zugang ermöglicht werden.Wind turbines Fortunately, they are increasingly being used. Unlike planes, whose propellers can be easily repaired on the ground, the Rotors of wind turbines are difficult to repair. Further have to from time to time to check, control and decrease direct access.

Zur Zeit werden Windkraftanlagen nur – Wenn überhaupt möglich – unter Zuhilfenahme teuren Zubehörs, Hubsteigern oder dergl. Von einzelnen Personen Repariert.to Wind turbines are only time - if at all possible - with the help of expensive accessories, Hubsteigern or the like. Of individual persons repaired.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Hebevorrichtung zu schaffen, mit der Reparaturpersonal in einfacher weise an alle zu Reparierenden stellen eines Rotors kommt,Of the Invention is therefore the object of a lifting device to create, with the repair staff in a simple way to all Repairing a rotor comes,

Da die Aufstellung von Kränen oder Hubsteiger meist aufgrund der Lage der Windkraftanlagen in Unbewohnten Gegenden sehr schwierig ist, wird vorgeschlagen, seile im Bereich der Rotornabe Zu befestigen. Auf der Rotorachse ist dies aufgrund der geringen räumlichen Verhältnisse meist Nicht möglich. Aus dem Motorhaus heraus wiederum ist zwar meist ein Zugang gewährleistet, Jedoch wird hier keine Aufhängevorrichtung für eine Reparaturvorrichtung geboten.There the setting up of cranes or elevators mostly due to the location of wind turbines in uninhabited Regions is very difficult, it is suggested ropes in the area the rotor hub To attach. This is due to the rotor axis the small spatial conditions usually not possible. Out In turn, the access to the engine house is usually guaranteed However, here is no suspension for one Repair device offered.

Erfindungsgemäß wird jedoch vorgeschlagen, die Rotoren selbst zur Aufhängung einer Hebebühne zu nutzen.However, according to the invention proposed to use the rotors themselves for suspending a lift.

Eine Hebebühne kann dabei mit einer zentralen Ausnehmung versehen sein, so dass um den senkrecht stehenden Rotor herum gegangen werden kann, während dieser Repariert wird. Die Hebebühne kann dabei Vorteilhafterweise an dem Mast der Windkraftanlage abgestützt werden So dass auch im Fall starken Wind keine Kräfte auf das Rotorblatt ausgeübt werden.A hydraulic ramp can be provided with a central recess, so that can be walked around the vertical rotor while this Repaired. The lift can Advantageously, be supported on the mast of the wind turbine So that even in the case of strong wind no forces are exerted on the rotor blade.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus nachfolgender Beschreibung Eines bevorzugten Ausführungsbeispiels der Erfindung anhand der beiliegenden Zeichnung.Further Features and advantages of the invention will become apparent from the following Description of a preferred embodiment of the invention with the enclosed drawing.

Dabei zeigt:there shows:

1 eine Rotornabe einer Windkraftanlage mit einem Ausführungsbeispiel einer Erfindungs-Gemäßer Hebevorrichtung, die an den beiden schräg nach oben stehenden Flügeln eines Rotoren befestigt ist, und 1 a rotor hub of a wind turbine with an embodiment of an invention according to the lifting device, which is attached to the two obliquely upstanding wings of a rotor, and

2 Eine Hebebühne, die um ein vertikal stehendes Rotorblatt herum Anhebbar ist, wobei das Rotorblatt Durch gestrichelte Linien in seiner Lage angedeutet ist. 2 A lifting platform that can be raised around a vertically standing rotor blade, wherein the rotor blade is indicated by dashed lines in its position.

Die in der 1 dargestellte Befestigung der Hebevorrichtung 10 an die nach oben weisenden Rotorblätter 12 ist leicht vom Turm, bzw. Maschinenhaus der Windkraftanlage aus befestigbar. Während der gesamten Reparatur verbleiben die Aufhängevorrichtungen 10 an die Rotorblätter 12.The in the 1 illustrated attachment of the lifting device 10 to the upward-pointing rotor blades 12 is easily attachable from the tower or machine house of the wind turbine. Throughout the repair remain the hangers 10 to the rotor blades 12 ,

Insbesondere wird vorgeschlagen, Rundschlingen oder Hebebänder zu verwenden, die nach Beendigung der Reparatur wieder einfach von den Rotorblätter 12 gelöst werden können.In particular, it is proposed to use round slings or lifting straps, which after completion of the repair again simply from the rotor blades 12 can be solved.

Vorteilhafterweise wird eine derartige Hebebühne 20 dass Komplette Rotorblattquerschnittes umfassen, um Zugang zu dem gesamten Umfang des Rotorblatts auf der jeweiligen Höhe zu ermöglichen. Beginnend von oben kann das Rotorblatt 12 repariert werden, ohne das ggf. bei späteren Reparatur die bereits reparierter stellen beschädigt werden.Advantageously, such a lift 20 complete rotor blade cross-section to allow access to the entire circumference of the rotor blade at the respective height. Starting from the top, the rotor blade can 12 be repaired, without this may be damaged in later repair the already repaired places.

Vorteilhafterweise wird eine Hebebühne 20 mit jeweils zwei Zug und zwei Sicherheits- Seilen versehen, So dass Sicherheitsaspekten voll genügt wird. Bügel 24 dienen dazu, eventuelle Gleichlaufschwankung beim Aufrollen der beiden seile zu Kompensieren.Advantageously, a lift 20 each with two train and two safety ropes provided so that safety aspects is fully sufficient. hanger 24 serve to compensate for any synchronization fluctuation when rolling up the two ropes.

Wie in der 2 zu sehen, wird insbesondere eine Hebebühne mit einer zentralen, rundum Umschlossenen Ausnehmung vorgeschlagen, die von unten her das zu Reparierenden Rotorblatt gebracht, zunächst angehoben und dann zur Reparatur langsam abgesenkt wird.Like in the 2 To see, in particular, a lifting platform with a central, all-round enclosed recess is proposed, which brought from below to be repaired rotor blade, first raised and then slowly lowered for repair.

Dabei wird insbesondere vorgeschlagen, Über Abstandhalter mit Räder 26, die Hebebühne 20 direkt am Mast einer Windkraftanlage abzustützen.It is proposed in particular, About spacers with wheels 26 , the lift 20 directly on the mast of a wind turbine support.

Um die Ausnehmung 30 herum wird durch Aluminium platten Vorteilhafterweise drei Seiten eine Standfläche geschaffen. Eine umlaufendes Geländer, wie bei Fensterreinigungs- Hebebühnen, ist außen vorgesehen.Around the recess 30 around aluminum plates are advantageously created three sides of a stand area. A circumferential railing, as in window cleaning lifts, is provided on the outside.
