Description

Kurzbeschreibung:Short description:

Die vorliegende Erfindung beschreibt eine vertikalmobile mitkletternde Hebe- und Montagevorrichtung und ein Verfahren zur Errichtung und Wartung von Türmen von Windenergieanlagen und von Windenergieanlagen außerhalb des Turmes.The present invention describes a vertical mobile climbing and mounting apparatus and method for erecting and maintaining towers of wind turbines and wind turbines outside the tower.

Stand der Technik:State of the art:

Windenergieanlagen unterschiedlicher Größe, Leistung und unterschiedlichen Typs verbreiten sich mehr und mehr in allen Ländern der Erde zur Erzeugung von elektrischer Energie aus der kinetischen Energie des Windes. Der Trend zu regenerativen Energien aus Wind, Sonne, Biomasse und Wasser hat sich in den vergangenen Jahren deutlich verstärkt und die Hersteller besonders im Bereich der sehr erfolgreichen Windenergie zum Bau immer größerer Windenergieanlagen angeregt.Wind turbines of different size, power and different types are spreading more and more in all countries of the world to generate electrical energy from the kinetic energy of the wind. The trend toward regenerative energies from wind, solar, biomass and water has increased significantly in recent years and manufacturers have encouraged the construction of ever larger wind turbines, particularly in the field of highly successful wind energy.

Dieser Zuwachs an Größe führt vor allem bei dem am weitesten verbreiteten Typ von Windenergieanlagen, dem des dreiblättrigen horizontalachsigen Rotors auf einem Turm, zunehmend zu Problemen, die z. T. ganz erheblich auf das Festhalten an bestehenden Bauprinzipien und Verfahren zurückzuführen sind.This increase in size, especially in the most widespread type of wind turbines, that of the three-blade horizontal axis rotor on a tower, increasingly causing problems such. T. are significantly due to the adherence to existing construction principles and procedures.

Es ist bekannt, daß Windenergieanlagen um so höhere Erträge aus dem über das Jahr verteilten Windangebot schöpfen können, je höher die Windenergieanlagen gebaut werden, da in größeren Höhen der Wind im Durchschnitt schneller und laminarer weht. Dementsprechend wurden in der jüngeren Vergangenheit verschiedene Turmtypen erprobt, um die Nabenhöhe sukzessive anzuheben und den Rotor in den ertragreicheren höheren Luftschichten zu positionieren (Hybridturm oder Gittermast). Dabei kommt es immer wieder zu Problemen mit den dabei angewandten Verfahren zur Errichtung. Die verfügbaren mobilen Schwerlastkräne können das zu montierende Gondelgehäuse nur bis zu ihrer maximalen Hubhöhe hieven. Soll die Gondel in größeren Höhen angebracht werden, müssen stationäre Kräne, wie sie aus dem Baugewerbe bekannt sind, installiert werden, deren maximale Hublast aber geringer ist.It is well known that the higher the wind turbines are built, the higher the yield of wind turbines, because at higher altitudes the wind blows faster and more laminarly on average. Accordingly, various tower types have been recently tested to gradually raise the hub height and position the rotor in the higher-yielding higher air layers (hybrid tower or lattice mast). It always comes back to problems with the process used to build it. The available heavy duty mobile cranes can only lift the nacelle housing to be mounted up to their maximum lifting height. If the nacelle is to be installed at higher altitudes, stationary cranes, as known from construction, must be installed, but their maximum lifting capacity is lower.

Die erforderlichen Montagemanöver mit den extrem schweren und großvolumigen Bauteilen unter Zuhilfenahme mobiler Schwerlastkräne sind wind- und wetteranfällig, was den Zeitplan schnell durcheinander bringt; sie erfordern zudem sehr viel Erfahrung des Kranführers und können leicht zu Beschädigungen der zu installierenden Bauteile führen.The required assembly maneuvers with the extremely heavy and large-volume components with the help of mobile heavy-duty cranes are wind and weather-prone, which quickly mix up the schedule; They also require a great deal of experience of the crane operator and can easily lead to damage to the components to be installed.

Die geschilderten Umstände machen den Zusammenbau und die Wartung von größer werdenden Windenergieanlagen sowohl on-shore, als auch off-shore zu einem zeitlich schlecht kalkulierbaren Risiko, das zudem immer größere Summen für die Bereitstellung geeigneter (mobiler) Schwerlastkräne erfordert.The circumstances described make the assembly and maintenance of growing wind turbines both on-shore and off-shore at a risk that is difficult to calculate at a time, and moreover requires ever larger sums for the provision of suitable (mobile) heavy-duty cranes.

Kommt zum Bau der Windenergieanlage ein Hybridturm zur Anwendung, sind zur Errichtung der Betonsektion in der Regel Klettergerüste erforderlich. Dieses Equipment und das dazugehörige Takt-Verfahren sind langsam unwirtschaftlich.If a hybrid tower is used for the construction of the wind turbine, climbing frames are usually required to construct the concrete section. This equipment and the associated clock method are slowly becoming uneconomical.

Zusammenfassend läßt sich feststellen, daß alle herkömmlichen Montagemanöver bei weiterem upscaling der Windenergieanlagen nicht mehr praktikabel sind und prinzipiell neue Verfahren zur Errichtung größerer und vor allem höherer Windenergieanlagen zur Anwendung kommen müssen. Ein „weitermachen, wie bisher” ist wenig praktikabel.In summary, it can be stated that all conventional assembly maneuvers with further upscaling of the wind turbines are no longer practicable and, in principle, new methods of constructing larger and above all higher wind turbines must be used. A "carry on as before" is not practical.

Aufgabe:Task:

Es ist die Aufgabe der Erfindung, ein Hebezeug und ein Verfahren für den Bau, die Wartung und die Demontage von Windenergieanlagen sowohl on-shore als auch off-shore vorzuschlagen, welches die Bereitstellung großer (mobiler) Schwerlastkräne mit hohen Hublasten entbehrlich macht, den Personalaufwand bei der Montage, sowie das Beschädigungsrisiko der zu montierenden Bauteile senkt, das Limit der maximalen Hubhöhe beseitigt und die Errichtung der Windenergieanlage, sowie die Wartung während der Betriebsphase und die Demontage oder einen Standortwechsel vereinfacht.It is the object of the invention to provide a hoist and a method for the construction, maintenance and disassembly of wind turbines both on-shore and off-shore, which makes the provision of large (mobile) heavy duty cranes with high lifting loads unnecessary, the personnel costs during installation, and reduces the risk of damage to the components to be mounted, eliminates the maximum lifting height limit and simplifies the installation of the wind turbine, as well as maintenance during the operating phase and disassembly or relocation.

Es ist die Aufgabe der Erfindung, den Turmschaft der Windenergieanlage als Kranturm für das vorgeschlagene Hebezeug heranzuziehen.It is the object of the invention to use the tower shaft of the wind energy plant as a crane tower for the proposed hoist.

Es ist die Aufgabe der Erfindung, eine in das Hebezeug integrierte Montageplattform vorzuhalten, welche den Zusammenbau der erforderlichen Komponenten der Windenergieanlage vereinfacht.It is the object of the invention to provide an integrated in the hoist mounting platform, which simplifies the assembly of the required components of the wind turbine.

Lösung des Problems:The solution of the problem:

Erfindungsgemäß wird diese Aufgabe durch ein Hebezeug verwirklicht, welches sich außerhalb der Turmkonstruktion befindet, dort während der Errichtungsphase mitwächst, und sich innerhalb der Turmkonstruktion auf und ab bewegen kann.According to the invention this object is achieved by a hoist, which is located outside the tower construction, grows there during the construction phase, and can move up and down within the tower construction.

Erfindungsgemäß wird diese Aufgabe dadurch verwirklicht, daß sich am unteren Ende des in den Turmschaft eingesteckten Hebezeuges eine Montageplattform befindet, die es ermöglicht, die durch das Hebezeug herbeigeschafften Bauteile sofort, praktikabel und mit weniger zusätzlichem Equipment zu montieren, als das beispielsweise bei Klettergerüsten der Fall ist.According to the invention this object is achieved in that at the lower end of the tower shaft inserted in the hoist an assembly platform is located, which makes it possible to bring brought by the hoist components immediately, practicable and with less additional equipment, as for example in climbing frames of the case is.

Figurenbeschreibung:Brief Description:

1 beschreibt den Stand der Technik in einer Übersicht: Die Figur zeigt eine Windenergieanlage üblicher Bauart mit ihren Komponenten Rotorblätter (1), Rotorblattaufhängung (2), Gondel (3) mit den darin befindlichen Bauteilen Getriebe (4) und Generator (5) zur Konversion der Rotationsbewegung in elektrische Energie, die drehbare Gondelaufhängung (6) auf dem Turmschaft (7), ggfs. einen kegelförmigen oder anders aufgeweiteten Turmsockel (8) und das Turmfundament (9), welches sämtliche Kräfte in den Baugrund (10) ableitet. Die Kraft des Windes (FΣW) kann vereinfacht als eine horizontal wirkende Kraft angenommen werden, die auf den Mittelpunkt des Rotors wirkt. 1 describes the prior art in an overview: The figure shows a wind turbine of conventional design with its components rotor blades ( 1 ), Rotor blade suspension ( 2 ), Gondola ( 3 ) with the components located therein transmission ( 4 ) and generator ( 5 ) for converting the rotational movement into electrical energy, the rotatable nacelle suspension ( 6 ) on the tower shaft ( 7 ), if necessary, a conical or otherwise expanded tower base ( 8th ) and the tower foundation ( 9 ), which transfers all forces into the ground ( 10 ). The force of the wind (F ΣW ) can be assumed in a simplified manner as a horizontally acting force acting on the center of the rotor.

2 beschreibt das erfindungsgemäße Verfahren und den erfindungsgemäßen Aufbau beispielhaft. Der Kran (1) umfaßt den Turmschaft (4) und bewegt sich mit Halteelementen (3) am Turmschaft, in der Regel eine Zylindermantelfläche in vertikaler Richtung, entlang. Im unteren Bereich des Krans befinden sich eine oder mehrere Montageplattformen (2) zur Endmontage der Turmschaftelemente. Die Errichtungshöhe (h2) des Turmes ist durch dieses Verfahren nicht limitiert. Die Lastaufnahme am Kranhaken (g3) kann frei gewählt werden. Erfindungsgemäß schlägt das Verfahren vor, diesen Kran (5) mit einer höheren Hubgeschwindigkeit lediglich für mittlere Lasten zu ertüchtigen, um die Bauteile des Krans und die Liftschiene nicht zu stark dimensionieren zu müssen. Alternativ oder zusätzlich kann ein weiterer Kran (6) mit einer höheren Hakenlast (g4) installiert sein, um schwere Lasten, wie beispielsweise die geriggte Windturbine zu heben. 2 describes the process according to the invention and the structure according to the invention by way of example. The crane ( 1 ) comprises the tower shaft ( 4 ) and moves with holding elements ( 3 ) on the tower shaft, usually a cylinder jacket surface in the vertical direction, along. In the lower part of the crane are one or more assembly platforms ( 2 ) for final assembly of the tower shaft elements. The construction height (h 2 ) of the tower is not limited by this method. The load suspension at the crane hook (g 3 ) can be freely selected. According to the invention, the method proposes to use this crane ( 5 ) with a higher lifting speed only for moderate loads in order not to have to dimension the components of the crane and the lift rail too much. Alternatively or additionally, another crane ( 6 ) with a higher hook load (g 4 ) to lift heavy loads such as the wind turbine.

3 zeigt beispielhaft, der Turmschaft ab einer gewissen Höhe durch Seile (1) abgespannt werden kann und somit die Standsicherheit des Kranturmes garantiert. 3 shows by way of example, the tower shaft from a certain height by ropes ( 1 ) and thus guarantees the stability of the crane tower.

4 zeigt beispielhaft, wie das gesamte Hebezeug am eine der Montage zum Boden zurückkehrt, um dort vom Turmschaft abgenommen zu werden. 4 shows by way of example how the entire hoist on one of the assembly returns to the ground to be removed there from the tower shaft.
