Description
Die Erfindung betrifft einen Turmdrehkran mit einem Turm aus mindestens einem Turmelement nach dem Oberbegriff des Anspruchs 1. Weiterhin betrifft die Erfindung ein Verfahren zur Montage eines Windturbinen-Rotorblattes.The invention relates to a tower crane with a tower of at least one tower element according to the preamble of claim 1. Furthermore, the invention relates to a method for assembling a wind turbine rotor blade.
Bei Turmdrehkranen, bei welchem der Turm aus einem oder mehreren Turmelementen besteht, welche in vertikaler Richtung miteinander verbunden werden, kann die Höhe des Turms durch den Einsatz weiterer Turmelemente vergrößert werden. Allerdings haben Turmdrehkrane eine maximale freistehende Hakenhöhe. Wird diese überschritten, muss der Turmdrehkran durch eine horizontale Verankerung an den zu errichteten Bauwerken befestigt werden. Hierdurch kann die maximal erreichbare Hakenhöhe deutlich vergrößert werden.In tower cranes, in which the tower consists of one or more tower elements, which are connected to each other in the vertical direction, the height of the tower can be increased by the use of additional tower elements. However, tower cranes have a maximum freestanding hook height. If this is exceeded, the tower crane must be secured by a horizontal anchorage to the structures to be constructed. As a result, the maximum achievable hook height can be significantly increased.
Bei derartigen Turmdrehkranen ist es möglich, durch den Einbau weiterer Turmelemente den Turmdrehkran mit dem Bauwerk wachsen zu lassen, wobei die Stabilität des Turmdrehkrans durch eine oder mehrere Bauwerksabspannungen gewährleistet ist. Ein Turmdrehkran mit einer derartigen Bauwerksabspannung ist bereits aus der
Dokument
Derartige Turmdrehkrane mit einer Bauwerksabspannung werden beispielsweise zur Errichtung von Windkraftanlagen verwendet. Bei der Montage derartiger Windkraftanlagen müssen die Rotorblätter von dem Kran während der Montage geführt werden. Standardgemäß werden die Rotorblätter während der Montage durch Seile vom Boden aus geführt. Die durch eine derartige Bodenführung aufbringbaren Seilzugkräfte sind sehr gering, so dass bei einer derartigen Montage nur sehr geringe Windgeschwindigkeiten zugelassen werden können. Darüber hinaus ergeben sich häufig bei der Führung der Seile vom Boden aus Platzprobleme, wenn beispielsweise die Windkraftanlage in einem Waldgebiet aufgestellt wird, in welchem die Platzverhältnisse am Boden teilweise sehr eingeschränkt sind.Such tower cranes with a building guy are used for example for the construction of wind turbines. When installing such wind turbines, the rotor blades must be guided by the crane during assembly. By default, the rotor blades are guided by ropes from the ground during assembly. The cable pull forces that can be applied by such a floor guide are very small, so that only very low wind speeds can be permitted with such an installation. In addition, often result in the leadership of the ropes from the ground space problems, for example, when the wind turbine is installed in a forest area in which the space on the ground are sometimes very limited.
Aufgabe der vorliegenden Erfindung ist es daher, einen gattungsgemäßen Turmdrehkran derart weiterzubilden, dass lange Gegenstände, wie beispielsweise Rotorblätter während der Montage in sehr hohen Höhen geführt werden können.Object of the present invention is therefore to develop a generic tower crane such that long objects such as rotor blades can be performed during assembly at very high altitudes.
Erfindungsgemäß wird diese Aufgabe mittels eines Turmdrehkrans nach Anspruch 1 gelöst.According to the invention this object is achieved by means of a tower crane according to claim 1.
Demnach weist ein Turmdrehkran einen Turm aus mindestens einem Turmelement, insbesondere Gitterstück, vorzugsweise mit einer Bauwerksabspannung, die mit mindestens einer Abspannstange zur Horizontalen an einem Bauwerk verankert ist und einen vertikal am Turm verfahrbaren Führungsrahmen auf, wobei an dem Führungsrahmen mindestens ein Positionierseil verstellbar befestigt ist. Über dieses am Führungsrahmen verstellbar befestigte Positionierteil kann der Abstand zwischen dem zu führenden Element, beispielsweise dem Rotorblatt und dem Führungspunkt deutlich verringert werden, so dass der zu montierende Gegenstand wesentlich stabiler geführt werden kann. Der Führungsrahmen kann jeweils in der Höhe am Turm vertikal nachgeführt werden. Hierdurch kann eine Führung ganz unabhängig von den Platzverhältnissen am Boden erfolgen. Des Weiteren kann auch eine Montage bei vergleichsweise höheren Windgeschwindigkeiten erfolgen. Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.Accordingly, a tower crane has a tower of at least one tower element, in particular lattice piece, preferably with a building guy, which is anchored to at least one tie rod horizontal to a building and a vertically movable on the tower guide frame, wherein at least one positioning is adjustably attached to the guide frame , By way of this positioning part which is adjustably mounted on the guide frame, the distance between the element to be guided, for example the rotor blade and the guide point, can be significantly reduced, so that the object to be mounted can be guided much more stably. The guide frame can be tracked vertically in each case in the tower height. As a result, a guide can be done regardless of the space conditions on the ground. Furthermore, an assembly can be carried out at comparatively higher wind speeds. Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim.
Erfindungsgemäß sind zwei Seilführungen zum Verfahren des Führungsrahmens vorhanden, die über eine Zweiseilwinde mit zwei Seiltrommeln verstellbar sind.According to the invention, two cable guides for moving the guide frame are present, which are adjustable via a Zileilwinde with two cable drums.
In bevorzugter Weise kann der Führungsrahmen über die zwei Seilführungen entlang des Führungsrahmens vertikal verfahrbar sein.In a preferred manner, the guide frame can be moved vertically along the guide frame via the two cable guides.
Die zwei Seilführungen weisen bevorzugt eine am Turm angeordnete Seiltrommel und eine an einem Kletterstück oder am Führungsstück angeordnete Umlenkrolle auf.The two cable guides preferably have a cable drum arranged on the tower and a deflection roller arranged on a climbing piece or on the guide piece.
Der Führungsrahmen ist gemäß der Erfindung U-förmig ausgebildet, so dass er den Turm an drei Seiten umgreift.The guide frame is U-shaped according to the invention, so that it engages around the tower on three sides.
Um eine noch höhere Stabilität zu erreichen und ein Abheben des U-förmigen Führungsrahmens vom Turm zu verhindern, ist der U-förmige Führungsrahmen an seinem offenen Ende abgewinkelt, um die Eckbereiche des Turms zu umgreifen.To achieve even greater stability and prevent lifting of the U-shaped guide frame from the tower, the U-shaped guide frame is angled at its open end to engage around the corner areas of the tower.
Besonders vorteilhaft weist der Führungsrahmen in den Eckbereichen des Turmes Rollen oder Gleitlager auf, über die er sich während der vertikalen Auf- und Abbewegung gegenüber dem Turm abstützt. Da das Gewicht des Führungsrahmens aufgrund seiner stabilen Ausführung recht hoch ist, kann der Führungsrahmen für Montage- und Transportzwecke teilbar sein.Particularly advantageously, the guide frame in the corner regions of the tower rollers or plain bearings, over which it is supported during the vertical up and down movement relative to the tower. Since the weight of the guide frame is quite high due to its stable design, the guide frame can be divisible for assembly and transport purposes.
Zur Verstellung des mindestens einen Positionierseils ist eine Winde am Führungsrahmen angeordnet. Vorteilhaft sind zwei unabhängig voneinander steuerbare Enden zur unabhängigen Verstellung von zwei Positionierseilen vorgesehen.To adjust the at least one positioning cable, a winch is arranged on the guide frame. Advantageously, two independently controllable ends for the independent adjustment of two positioning cables are provided.
Zusätzlich können am Führungsrahmen teleskopierbare Streben angeordnet sein, die einerseits zur Führung der Positionierseile dienen und andererseits als Dämpfer dienen, falls ein Kontakt des zu führenden Gegenstands, beispielsweise des Rotorblatts und der Streben auftreten sollte.In addition, telescoping struts can be arranged on the guide frame, which on the one hand serve to guide the positioning ropes and on the other hand as a damper serve, if a contact of the leading object, such as the rotor blade and the struts should occur.
Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung sind die am Führungsrahmen vorgesehenen Führungspunkte für die Positionierseile um den Turm herum rotierbar. Hierzu sind geeignete Führungen am Führungsrahmen vorgesehen.According to a particularly advantageous embodiment of the invention, the guidance points provided on the guide frame for the positioning cables are rotatable about the tower. For this purpose, suitable guides are provided on the guide frame.
Der Führungsrahmen kann zusätzlich als Personen- und/oder Warenaufzug dienen. Zur Verwendung als Personenauszug sind hier allerdings zwei unabhängige Seilführungen zur Vertikalverschiebung des Führungsrahmens notwendig.The guide frame can additionally serve as passenger and / or goods lift. For use as a personal statement, however, two independent cable guides for vertical displacement of the guide frame are necessary here.
Zum Gewichtsausgleich beim vertikalen Verfahren des Führungsrahmens ist vorzugsweise ein Ausgleichsgewicht vorgesehen, ähnlich wie dies aus der üblichen Aufzugstechnik bekannt ist.To balance the weight of the vertical movement of the guide frame, a balance weight is preferably provided, similar to that known from conventional elevator technology.
Weiterhin umfasst die Erfindung ein Verfahren zu Montage eines Windturbinen-Rotorblattes nach einem der Ansprüche 14 und 15.Furthermore, the invention comprises a method for mounting a wind turbine rotor blade according to one of
