Description

Fördervorrichtung zur Montage eines Turms Conveying device for mounting a tower

Die Erfindung betrifft eine Fördervorrichtung zur Montage eines Turms mit einem Gleis, das in einer Längsrichtung des Turms an einer Außenseite des Turms verläuft und mit einem Fördermittel, an dem ein Turmelement lagerbar ist zum Fördern des Turmelements auf dem Gleis von einem Anlieferungsniveau zu einem Montageort an dem Turm.The invention relates to a conveyor device for mounting a tower with a track which extends in a longitudinal direction of the tower on an outer side of the tower and with a conveying means, on which a tower element is storable for conveying the tower element on the track from a delivery level to a mounting location the tower.

Bei Montage und Wartung von Windkraftanlagen werden mobile Krane eingesetzt, deren Hubhöhe die Bauhöhe der Windkraftanlage überragen muss. Mit dem wachsenden Bedarf nach immer größeren Windkraftanlagen steigen auch die Anforderungen an die Hubhöhe der zu verwendenden Krane. Andererseits sind zur Montage von Türmen aus EP 1 057 770 A2 und DE 102 34 299 B4 gleisgebundene Fördervorrichtungen der eingangs genannten Art bekannt. Die Fördermittel dieser bekannten Fördervorrichtungen werden auf einem Anlieferungsniveau - typischer Weise das umgebende Bodenniveau am unteren Ende des Turms - mit dem jeweils nächsten Turmelement beladen und fördern dieses zur Spitze des Stumpfs. Die bekannten Fördervorrichtungen erfordern zusätzliche Handhabungseinrichtungen - insbesondere Krane - zum Aufnehmen des Turmelements auf dem Fördermittel.When installing and maintaining wind turbines, mobile cranes are used whose lifting height must exceed the height of the wind turbine. With the growing demand for ever larger wind turbines, the demands on the lifting height of the cranes to be used also increase. On the other hand, track-mounted conveying devices of the type mentioned in the introduction are known for mounting towers from EP 1 057 770 A2 and DE 102 34 299 B4. The conveying means of these known conveying devices are loaded at a delivery level - typically the surrounding ground level at the lower end of the tower - with the next tower element and convey this to the top of the stump. The known conveying devices require additional handling devices - in particular cranes - for receiving the tower element on the conveyor.

Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde, den organisatorischen und gerätetechnischen Aufwand der Montage eines Turms zu vermindern.The invention has for its object to reduce the organizational and equipment expense of installing a tower.

Lösungsolution

Ausgehend von den bekannten Verfahren wird nach der Erfindung vorgeschlagen, eine Handhabungseinrichtung des Fördermittels zum Aufnehmen des Turmelements von dem Anlieferungsniveau, zum Lagern des Turmelements an dem Fördermittel und zum Positionieren des Turmelements für die Montage an dem Montageort vorzusehen. Durch die Integration der Handhabungseinrichtung in das Fördermittel sind weitere Handhabungseinrichtungen zur Montage des Turmelements entbehrlich. Vorzugsweise weist die Handhabungseinrichtung einer erfindungsgemäßen Fördervorrichtung mindestens einen Arm aus mehreren untereinander gelenkig verbundenen Segmenten und jeder Arm an einem jeweils freien Ende ein Aufnahmeelement zum Aufnehmen des Turmelements auf. Derartige „Roboterarme" können sehr variabel positioniert werden. Beispielsweise kann ein auf demStarting from the known methods, it is proposed according to the invention to provide a handling device of the conveying means for receiving the tower element from the delivery level, for supporting the tower element on the conveying means and for positioning the tower element for mounting at the assembly site. By integrating the handling device into the conveying means, further handling devices for mounting the tower element are dispensable. Preferably, the handling device of a conveying device according to the invention at least one arm of a plurality of mutually articulated segments and each arm at a respective free end a receiving element for receiving the tower element. Such "robot arms" can be positioned very variably

Anlieferungsniveau angeliefertes Turmelement auch aufgenommen werden, wenn es nicht exakt an einer vorgegebenen Stelle steht. So kann eine solche Fördervorrichtung bei der Montage von Offshore- Windanlagen mit Anlieferung der Turmelemente per Schiff zum Einsatz gelangen. Mittels einer erfindungsgemäßen Fördervorrichtung mit einem oder mehrerenDelivery level supplied tower element also be included if it is not exactly at a predetermined location. Thus, such a conveyor device can be used in the assembly of offshore wind turbines with delivery of the tower elements by ship. By means of a conveying device according to the invention with one or more

Roboterarmen (oder mit einer anderen, hierfür angepassten Handhabungseinrichtung) können nicht nur rohrförmige Teile des Turms selbst zur Spitze eines Stumpf gefördert und dort montiert, sondern auch weitere Turmelemente wie der Generator, ein Getriebe, die Nabe, eine Nabenlagerung waagrecht in eine geschlossen vormontierte Gondel einer Windkraftanlage eingeführt werden. Weiterhin können ebenso außen am Turm anzubauende Turmelemente wie insbesondere Rotorblätter einer Windkraftanlage zum jeweiligen Montageort oder zur Wartung oder Demontage zurück zum Anlieferungsniveau gefördert werden.Robotic arms (or with another, adapted handling device) can not only tubular parts of the tower itself promoted to the top of a stump and mounted there, but also other tower elements such as the generator, a gearbox, the hub, a hub bearing horizontally in a closed preassembled nacelle a wind turbine are introduced. Furthermore, tower elements to be mounted on the outside of the tower, in particular rotor blades of a wind power plant, can also be conveyed back to the delivery level for the respective installation site or for maintenance or disassembly.

Eine erfindungsgemäße Fördervorrichtung kann insbesondere genau einen solchen Arm mit drei Segmenten aufweisen. Eine solche Handhabungseinrichtung zeichnet sich durch minimalen gerätetechnischen Aufwand bei zugleich größtmöglicher Beweglichkeit aus - hydraulische Dreh- und Schwenkantriebe in Verbindung mit hydraulischer Teleskopierbarkeit der Segmente erlauben eine Bewegung der Last translatorisch in und rotatorisch um drei Achsen. Besonders bevorzugt weist eine derart mit einem oder mehreren „Roboterarmen" ausgestattete erfindungsgemäße Fördervorrichtung elektro-hydraulische Antriebe zum Bewegen der Segmente auf. Hydraulische Antriebe sind beispielsweise für schwere Klappenantriebe und für Handhabungseinrichtungen - auch für schwere Lasten bis zu 30 1 - aus der Schmiedetechnik allgemein bekannt. Besonders vorteilhafter Weise weist eine erfindungsgemäße Fördervorrichtung einen Seilzug zum Ziehen des Fördermittels zu der Spitze des Stumpfs auf. Alternativ kann das Fördermittel auch einen eigenen motorischen Antrieb aufweisen und sich an einer in Längsrichtung des Turms verlaufenden Zahnstange emporziehen. Bei der Montage eines Turms mit einer solchen erfindungsgemäßen Fördervorrichtung wird bevorzugt zum Anbringen des Turmelements an der Spitze die Verankerung des Seilzugs gelöst und der Seilzug an dem Turmelement wieder verankert. Das erneute Verankern des Seilzugs kann hierbei unmittelbar nach dem Lösen der ersten Verankerung oder erst nach dem Anbringen des Turmelements an der Spitze des Stumpfs erfolgen. In einer besonders vorteilhaften Ausführungsform weist das Fördermittel einer erfindungsgemäßen Fördervorrichtung einen Anker auf zum Verankern des Fördermittels an einer Ankereinrichtung des Stumpfs. Wird das Fördermittel mittels eines Seilzugs an dem Stumpf emporgezogen, dann wird so das Lösen und erneute Verankern des Seilzugs erst möglich. Darüber hinaus sichert das Verankern des Fördermittels die weitere Handhabung des auf der Spitze des Stumpfs anzubringenden Turmelements. Alternativ kann das Fördermittel - wie der aus DE 197 41 988 Al bekannte Mobilkran - an den Stumpf gebunden werden.In particular, a conveying device according to the invention can have exactly one such arm with three segments. Such a handling device is characterized by minimal equipment expense at the same time the greatest possible mobility - hydraulic rotary and rotary actuators in conjunction with hydraulic telescoping of the segments allow movement of the load translationally and rotationally about three axes. Particularly preferably, a conveying device according to the invention equipped with one or more "robot arms" has electrohydraulic drives for moving the segments. <br/><br/> Hydraulic drives are generally known, for example for heavy damper actuators and handling devices - even for heavy loads of up to 30 l - from forging technology , Particularly advantageously, a conveying device according to the invention has a cable pull for pulling the conveying means to the tip of the stump. Alternatively, the conveyor may also have its own motor drive and pull up on a running in the longitudinal direction of the tower rack. When mounting a tower with such a conveyor device according to the invention, the anchoring of the cable is preferably solved for attaching the tower element at the top and anchored the cable to the tower element again. The re-anchoring of the cable can be done immediately after the release of the first anchor or only after the attachment of the tower element at the top of the stump. In a particularly advantageous embodiment, the conveying means of a conveying device according to the invention has an armature for anchoring the conveying means to an anchor device of the stump. If the conveyor is pulled up by means of a cable at the stump, then the release and re-anchoring of the cable is only possible. In addition, anchoring the conveyor secures further handling of the tower element to be mounted on the top of the stump. Alternatively, the conveying means - like the mobile crane known from DE 197 41 988 A1 - can be bound to the stump.

Vorzugsweise weist an dem Stumpf das Gleis mindestens eine im Wesentlichen der Außenseite zugewandte Lauffläche auf. Das Fördermittel kann sich an einer solchen Lauffläche gegen ein Abkippen von der Außenseite des Turmsegments abstützen.Preferably, at the stump the track has at least one running surface substantially facing the outside. The conveyor can be supported on such a tread against tipping from the outside of the tower segment.

Montage und Wartung einer Windkraftanlage ist unter Verwendung einer erfindungsgemäßen Fördervorrichtung weitgehend witterungsunabhängig. Gegenüber den bekannten Fördervorrichtungen, insbesondere gegenüber der Verwendung sehr großer Krane sind die einzusetzenden Geräte einfach aufgebaut und leicht zu transportieren und dadurch preiswert in größeren Stückzahlen herstellbar und kurzfristig verfügbar.Installation and maintenance of a wind turbine is largely weather-independent using a conveyor device according to the invention. Compared to the known conveying devices, in particular over the use of very large cranes, the devices to be used are simple in construction and easy to transport and thus inexpensive to produce in larger quantities and available at short notice.
