Definitions
- the present invention relates to a lifter and a method of using the lifter.
- a device of particularly high weight is intended as the upper conclusion of such buildings, such a crane must not only have a certain height, but also be designed so that he can pick up correspondingly weighty devices and put on the otherwise largely finished building.
- a building with a particularly heavy top unit may serve a wind turbine for generating electricity from wind power: such wind turbines have u. a. a very high tower (usually much more than 100 m) and, on top of the tower, a very heavy generator system. Since the generator system is placed on this after building the tower, the necessary crane must be designed to be large and stable. As a result, a lot of space is needed at the location. Accordingly consuming, especially space consuming, is also the transport of such a crane to and from the site of the wind turbine.
- the object of the present invention is therefore to provide a lifting device which is less expensive than a crane and easier to transport than a crane, and to provide a method for using such a lifting device.
- FIG. 1 shows the lifting device according to the invention in plan view with an inner tube 1 and an outer tube 2.
- the two tubes 1, 2 are arranged concentrically to each other.

Description
Die vorliegende Erfindung betrifft ein Hebegerät sowie ein Verfahren zum Verwenden des Hebegeräts.The present invention relates to a lifter and a method of using the lifter.
Für das Errichten von Gebäuden, insbesondere das Errichten hoher Gebäude, werden häufig Kräne benötigt. Wenn nun als oberer Abschluss solcher Gebäude ein Gerät von besonders hohem Gewicht vorgesehen ist, muss ein solcher Kran nicht nur eine bestimmte Höhe aufweisen, sondern auch noch so konstruiert sein, dass er entsprechend gewichtige Geräte hochheben und auf das ansonsten weitgehend fertige Gebäude aufsetzen kann. Als Beispiel für ein solches Gebäude mit einem besonders schweren obersten Gerät mag eine Windkraftanlage zum Erzeugen von Strom aus Windkraft dienen: solche Windkraftanlagen weisen u. a. einen sehr hohen Turm (meist deutlich mehr als 100 m) sowie, obenauf auf dem Turm, eine sehr schwere Generatoranlage auf. Da die Generatoranlage erst nach Errichten des Turms auf diesen aufgesetzt wird, muss der dazu notwendige Kran entsprechend groß und stabil ausgestaltet sein. Am Standort wird demzufolge auch viel Platz benötigt. Entsprechend aufwendig, insbesondere auch platzaufwendig, ist dabei auch der Transport eines solchen Krans zum und vom Aufstellungsort der Windkraftanlage.For the construction of buildings, especially the construction of tall buildings, cranes are often needed. Now, if a device of particularly high weight is intended as the upper conclusion of such buildings, such a crane must not only have a certain height, but also be designed so that he can pick up correspondingly weighty devices and put on the otherwise largely finished building. As an example of such a building with a particularly heavy top unit may serve a wind turbine for generating electricity from wind power: such wind turbines have u. a. a very high tower (usually much more than 100 m) and, on top of the tower, a very heavy generator system. Since the generator system is placed on this after building the tower, the necessary crane must be designed to be large and stable. As a result, a lot of space is needed at the location. Accordingly consuming, especially space consuming, is also the transport of such a crane to and from the site of the wind turbine.

Mittels einer solchen Ausführungsform des erfindungsgemäßen Hebegeräts lässt sich der Hochbau, im Beispiel die Windkraftanlage, errichten. Der Turmteil solcher Windkraftanlagen wird bekanntlich aus mehreren übereinander in mehreren Etagen angeordneten Schalen (üblicherweise vorgefertigte Betonschalen) errichtet, wobei jede Etage wiederum aus mehreren seitlich aneinander stoßenden Schalenelementen S gebildet wird. Die Schalenelemente S einer Etage weisen naturgemäß eine gegebene Höhe auf, wobei diese Höhe von Etage zu Etage verschieden sein kann.By means of such an embodiment of the lifting device according to the invention, the building construction, in the example, the wind turbine, build. The tower part of such wind turbines is known to be constructed of a plurality of shells arranged one above the other in several floors (usually prefabricated concrete shells), each floor in turn being formed of a plurality of laterally abutting shell elements S. The shell elements S a floor naturally have a given height, which height may vary from floor to floor.
Zunächst wird das Hebegerät, vorzugsweise unter Verwendung der Bodenplatte B, am Ort des zu errichtenden Hochbaus positioniert. Auf dem Kopfteil P wird ein Abschlussteil AT des zu errichtenden Hochbaus montiert. Im vorliegenden Beispiel einer zu errichtenden Windkraftanlage ist dies insbesondere die Generatoranlage, mittels derer im späteren Betrieb der Windkraftanlage Strom erzeugt wird. Im Ausführungsbeispiel ist nun angenommen, dass das Hebegerät insgesamt niedriger ist als die Schalenelemente der untersten Etage, also der ersten Etage des Hochbaus, hoch sind. Somit befindet sich die Unterkante der Kopfplatte P in einer niedrigeren Höhe als diese Schalenelemente hoch sind. Deshalb wird nun das eine Rohr 1, im Ausführungsbeispiel das Innenrohr 1 des Hebegeräts, mittels des Hebemittels 30 solange angehoben, bis sich die Unterkante der Kopfplatte P in einer größeren Höhe befindet als die Schalenelemente S der untersten Etage, also der ersten Etage des Hochbaus, hoch sind. Anschließend werden die Schalenelemente S der ersten Etage als unterste Etage des zu errichtenden Hochbaus montiert.First, the lifter, preferably using the bottom plate B, positioned at the site of the building to be built. On the top part P, a final part AT of the building to be erected is mounted. In the present example of a wind turbine to be constructed, this is in particular the generator system, by means of which electricity is generated during later operation of the wind power plant. In the embodiment, it is now assumed that the lifting device is lower overall than the shell elements of the lowest floor, so the first floor of the building, are high. Thus, the lower edge of the top plate P is at a lower level than these shell elements are high. Therefore, now the one
Nun wird das Innenrohr 1 mittels des Hebemittels 30 soweit abgesenkt, bis die Kopfplatte P auf den soeben montierten Schalenelementen S aufliegt. Dieses Absenken, das auch bei jeder weiteren Etage durchgeführt wird, ist in
Nun wird wieder das eine der beiden Rohre 1, 2, nämlich im Beispiel das Innenrohr 1, durch Ziehen am Hebemittel 30 soweit nach oben gezogen, bis sich die Unterkante der darauf ruhenden Kopfplatte P, vom Untergrund aus gerechnet, in einer größeren Höhe befindet als die Höhe der bereits montierten Schalenelemente S der ersten Etage zuzüglich der Höhe der Schalenelemente S der noch zu montierenden zweiten Etage beträgt. Ist diese Höhe erreicht, werden nun die Schalenelemente S der zweiten Etage des zu errichtenden Hochbaus auf denen der ersten Etage montiert.Now again, one of the two
Für jede weitere noch zu montierende Etage an Schalenelementen S wiederholt sich nun die Prozedur: Absenken des Innenrohrs 1, bis die Unterseite der Kopfplatte P auf der Oberseite der Schalenelemente S der zuletzt montierten Etage aufliegt, Anheben des Innenrohrs 1 die in eine Höhe, die höher ist als die Gesamthöhe aller bislang montierten Schalenelemente S (d. h. also, der bislang montierten Etagen) zuzüglich der Höhe von weiteren Schaltelementen S einer weiteren noch zu errichtenden Etage, Montage dieser Schalenelemente S dieser weiteren noch zu errichtenden Etage. Daran schließen sich dann wiederum ein Absenken des Innenrohrs 1 und die weiteren in diesem Absatz beschriebenen Verfahrensschritte an. Diese Schritte werden dann insgesamt sooft wiederholt, bis die Schalenelemente S sämtlicher zu erstellender Etagen montiert sind. Dies ist in
