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 DE 20 2011 100 477 U bekannt.In such tower cranes, it is possible to grow by installing additional tower elements, the tower crane with the building, the stability of the tower crane is ensured by one or more structural bracing. A tower crane with such a building guy is already out of DE 20 2011 100 477 U known.
  • Dokument US 2011 0094987 A1 offenbart auch eine Anordnung zur Montage eines Windturbinen-Rotorblattes.document US 2011 0094987 A1 also discloses an assembly for mounting a wind turbine rotor blade.
  • 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 claims 14 and 15.

  • Figur 1 zeigt einen Turmdrehkran 10, der über eine an sich bekannte Bauwerksabspannung 12 mit einer zu erstellenden Windkraftanlage 14 verbunden ist. Der Turmdrehkran 10 dient zum Aufbau der Windkraftanlage. Im hier dargestellten Ausführungsbeispiel ist über ein Lastseil 16 des Turmdrehkrans 10 ein Rotorblatt 18 des Turmdrehkrans aufgenommen, um dieses an der Nabe 20 der Windkraftanlage zu montieren. FIG. 1 shows a tower crane 10, which is connected via a known per se building guy 12 with a wind turbine 14 to be created. The tower crane 10 is used to build the wind turbine. In the embodiment shown here, a rotor blade 18 of the tower crane is received via a load cable 16 of the tower crane 10 in order to mount this on the hub 20 of the wind turbine.
  • Dabei ist das Lastseil 16 im hier dargestellten Ausführungsbeispiel mit einer Verstelleinheit 22 verbunden, die Winden zur Pitch-Neige-Winkelverstellung des aufgenommenen Rotorblatts 18 aufweist. Das Rotorblatt 18 ist über entsprechende Seile 24 mit einem Rotorblattgreifer 26 verbunden, mittels dem in bekannter Weise das Rotorblatt 18 umgriffen werden kann.Here, the load cable 16 is connected in the illustrated embodiment with an adjustment unit 22, the winches for pitch-tilt angle adjustment of the recorded rotor blade 18 has. The rotor blade 18 is connected via corresponding ropes 24 with a rotor blade gripper 26, by means of which the rotor blade 18 can be encompassed in a known manner.
  • Am Rotorblattgreifer 26 sind zwei Positionierseile 28 angelenkt, die mit ihren anderen Enden an einem Führungsrahmen 30 befestigt sind. Der Führungsrahmen 30 ist in Doppelpfeilrichtung a vertikal entlang des Turms 11 des Turmdrehkrans verfahrbar. Die Positionierseile 28 können in ihrer Länge über entsprechende Winden 32 verstellt werden.On the rotor blade gripper 26 two positioning cables 28 are articulated, which are fastened with their other ends to a guide frame 30. The guide frame 30 is vertically movable in the double arrow direction a along the tower 11 of the tower crane. The positioning cables 28 can be adjusted in length via corresponding winches 32.
  • Die Vertikalverstellung des Führungsrahmens 30 erfolgt im hier dargestellten Ausführungsbeispiel über zwei Seile 34, die über einen Antrieb 36 verfahren werden können. Der Antrieb 36 ist im hier dargestellten Ausführungsbeispiel im Bodenbereich des Turmdrehkrans 10 angeordnet. Der Antrieb besteht hier aus einer Zweiseilwinde mit zwei Seiltrommeln. Die Seile 34 werden über Umlenkrollen 38 geführt, die in einer Kranturmklettereinheit 40 vorgesehen sind.The vertical adjustment of the guide frame 30 takes place in the illustrated embodiment via two cables 34, which can be moved by a drive 36. The drive 36 is arranged in the illustrated embodiment in the bottom region of the tower crane 10. The drive here consists of a two-way winch with two rope drums. The ropes 34 are guided over deflection rollers 38, which are provided in a crane tower climbing unit 40.
  • In der Detaildarstellung gemäß Figur 2 ist eine leicht abgewandelte Ausführungsvariante zur Figur 1 dargestellt. Hier ist am Turm 11 der in Doppelpfeilrichtung a verfahrbare Führungsrahmen 30 dargestellt, wobei zur Vertikalverschiebung hier ein Seil 34 dient, welches wiederum über Umlenkrollen 38 einer Kranturmklettereinrichtung 40 geführt ist. Dieses Seil 34 läuft jedoch über entsprechende Winden 42, die im Führungsrahmen 30 angeordnet sind. Durch die Verstellung der Winden 42 verlängert sich das Seil 34 oder verkürzt sich, so dass hier die Vertikalbewegung des Führungsrahmens 30 vollzogen wird.In the detail view according to FIG. 2 is a slightly modified variant of the FIG. 1 shown. Here on the tower 11 of the movable in the double arrow direction a guide frame 30 is shown, wherein the vertical displacement here Rope 34 is used, which in turn is guided over deflection rollers 38 of a Kranturmklettereinrichtung 40. However, this cable 34 runs over corresponding winches 42, which are arranged in the guide frame 30. By adjusting the winches 42, the cable 34 is extended or shortened, so that here the vertical movement of the guide frame 30 is completed.
  • Figur 3 zeigt eine Querschnittsansicht des Führungsrahmens 30, aus welcher die Anordnung gegenüber dem Turm 11 des Turmdrehkrans deutlich wird. Der Turm 11 ist über eine Bauwerkabspannung 12 mit der Windkraftanlage 14 verbunden. FIG. 3 shows a cross-sectional view of the guide frame 30, from which the arrangement relative to the tower 11 of the tower crane is clear. The tower 11 is connected via a Bauwerkabspannung 12 with the wind turbine 14.
  • Der Führungsrahmen 30 weist eine U-Form auf, wie in Figur 3 dargestellt. An seinem offenen Ende ist der U-förmige Führungsrahmen 30 allerdings abgewinkelt, um die Eckbereiche des Turms zu umgreifen, wie unter der Positionsnummer 44 verdeutlicht wird. Im Bereich der Eckstiele 13 des Turms 11 sind hier nicht im Einzelnen dargestellte Rollen- oder Gleitlager 46 im Führungsrahmen vorgesehen. Die hier in Figur 3 nicht im Einzelnen dargestellte Rollen- oder Gleitlagerführung kann zum Turm hin schwenkbar ausgebildet sein, um die Montage zu vereinfachen.The guide frame 30 has a U-shape, as in FIG. 3 shown. However, at its open end, the U-shaped guide frame 30 is angled to encompass the corner areas of the tower, as illustrated by the position number 44. In the area of the corner stems 13 of the tower 11 not shown in detail roller or sliding bearings 46 are provided in the guide frame. The here in FIG. 3 not shown in detail roller or slide bearing guide can be designed to pivot towards the tower to simplify installation.
  • Mit 48 sind zwei Angriffspunkte der Positionierseile 28 dargestellt. Für den Fall, dass nur ein Positionierseil verwendet wird, ist der Angriffspunkt 50 zu wählen.48, two points of attack of Positionierseile 28 are shown. In the event that only one positioning rope is used, the point of application 50 is to be selected.
  • In der Figur 4 wird eine alternative Ausführungsform des Führungsrahmens gezeigt. Hier weist der Führungsrahmen Eckführungselemente 50 auf, die auf den jeweiligen Eckstielen 13 des Turms 11 aufgesetzt sind Die Eckführungselemente enthalten jeweils drei Rollenlager 52, 54 und 56.

They are each connected via connecting elements 58 with each other.
  • Im hier dargestellten Ausführungsbeispiel wurde die Erfindung anhand einer stabileren Führung eines Rotorblattes erläutert. Selbstverständlich kann im Rahmen der Erfindung anstelle eines Rotorblatts auch jeder beliebige andere große und flächige Körper in eine entsprechende Montageposition gebracht werden. Die Erfindung ist also nicht auf die Montage von Windkraftanlagen beschränkt.In the embodiment shown here, the invention has been explained with reference to a more stable guidance of a rotor blade. Of course, in the context of the invention, any other large and flat body can be brought into a corresponding mounting position instead of a rotor blade. The invention is therefore not limited to the installation of wind turbines.
  • Im hier dargestellten Ausführungsbeispiel sind die Positionierseile 28 an dem Rotorblattgreifer angelenkt. Selbstverständlich können die Positionierseile auch unmittelbar am Rotor bzw. an einem anderen zu positionierenden Bauteil angeschlagen werden.
    Figur 5 zeigt eine Kranturmklettereinrichtung 40 gemäß einer weiteren Ausführungsform der Erfindung. Diese wird als letztes Turmstück eingeklettert und bleibt somit immer an oberster Position am Turmdrehkran 10. Hier ist die Position der Umlenkrolle 38 und eines Hubwerks 36' zum vertikalen Verfahren des Führungsrahmens 30 gezeigt.
    In the embodiment shown here, the positioning cables 28 are articulated on the rotor blade gripper. Of course, the positioning cables can also be struck directly on the rotor or on another component to be positioned.
    FIG. 5 shows a crane climbing device 40 according to another embodiment of the invention. This is clamped as the last tower piece and thus always remains at the top position on the tower crane 10. Here, the position of the guide roller 38 and a hoist 36 'for vertical movement of the guide frame 30 is shown.
  • Mit dem zuvor beschriebenen Turmdrehkran 10 kann beim Aufbau einer Windkraftanlage die Ausrichtung des Rotorblatts in vorteilhafter Weise über den am Turm 11 angeordneten Führungsrahmen 30 erfolgen. Dabei kann der Kranführer zur vertikalen Führung des Rotorblattes bzw. Anbauteils über eine Fernsteuerung und eine Kamera verfügen. Zur horizontalen Führung bzw. Ausrichtung des Rotorblattes verfügt der Kranfahrer ebenfalls über eine Fernsteuerung und eine Kamera sowie über eine Steuerung zum Verfahren der Positionierseile 28. Die Pitch-Neige-Winkelverstellung des Rotorblattes entlang einer Längsachse übernimmt hierbei die Verstelleinheit 22.With the tower crane 10 described above, in the construction of a wind turbine, the alignment of the rotor blade can advantageously take place via the guide frame 30 arranged on the tower 11. The crane operator can have the vertical guidance of the rotor blade or attachment via a remote control and a camera. For horizontal guidance or alignment of the rotor blade, the crane operator also has a remote control and a camera and a controller for moving the positioning ropes 28. The pitch-tilt angle adjustment of the rotor blade along a longitudinal axis takes over the adjustment unit 22.
  • Schließlich zeigen die Figuren 6 und 7 Details eines baulich abgewandelten Führungsrahmens 30 mit modifizierten Eckführungselementen 50'. Die hier dargestellten Eckführungselemente 50' weisen jeweils zwei Rollenlager 52' und 54' auf, die auf den hier nicht dargestellten Eckstielen 13 des Turmes 11 aufgesetzt sind.Finally, the show FIGS. 6 and 7 Details of a structurally modified guide frame 30 with modified corner guide elements 50 '. The corner guide elements 50 'shown here each have two roller bearings 52' and 54 ', which are placed on the corner stems 13 of the tower 11, not shown here.
  • Zur einfachen Montage sind die Rollenlager 52' und 54' in einem schwenkbaren Blech 70 gelagert. In Fig. 7 ist das Blech in eine Montageposition geschwenkt, in der es durch einen Bolzen 68 gesichert werden kann. In dieser Montageposition kann der Führungsrahmen an die Eckstiele 13 des Turmes 11 angenähert werden. Durch Verschwenken des Blechs 70 kann dieses dann in die montierte Endposition gebracht und dort, wie in Figur 6 gezeigt wieder verbolzt werden. In dieser Position stehen die Rollenlager 52' und 54' in Kontakt mit den Eckstielen 13. Durch diese konstruktive Ausgestaltung läßt sich der Führungsrahmen einfach montieren.For ease of assembly, the roller bearings 52 'and 54' are mounted in a pivotable plate 70. In Fig. 7 the sheet is pivoted to a mounting position in which it can be secured by a bolt 68. In this mounting position, the guide frame can be approximated to the corner posts 13 of the tower 11. By pivoting the sheet 70, this can then be brought into the mounted end position and there, as in FIG. 6 be shown again bolted. In this position stand the roller bearings 52 'and 54' in contact with the corner stems 13. By this structural configuration, the guide frame can be easily installed.
