Description
Die Erfindung betrifft eine Vorrichtung zum Montieren oder Demontieren eines Krans.The invention relates to a device for mounting or dismounting a crane.
Aus dem Stand der Technik ist eine Vielzahl von Kranen, insbesondere von Turmdrehkranen, bekannt. Zum Klettern von Turmdrehkranen ist es bekannt, dass an die zu kletternden Turmstücke eine Traverse angebracht wird. Das Einhängen der Traverse in den Montagehaken eines am Erdboden befindlichen Turmstücks erfolgt durch einen Monteur, der in das zu kletternde Turmstück steigt und den Montagehaken derart führt, dass das zu kletternde Turmstück sicher in dem Montagehaken aufgenommen wird.A large number of cranes, in particular tower cranes, are known from the prior art. For climbing tower cranes, it is known that a crossbeam is attached to the tower pieces to be climbed. The hanging of the traverse in the mounting hook of a tower piece located on the ground is done by an installer who climbs into the tower section to be climbed and leads the mounting hooks such that the tower to be climbed tower piece is securely received in the mounting hook.
Die mit dem Montagehaken aufgenommene Traverse wird in eine Einbauposition an eine Montagelaufkatze übergeben, die an einem Montageturm angebracht ist. Das Übergeben des zu kletternden Turmstücks an die Montagelaufkatze erfolgt durch Absetzen der Traverse in die Montagelaufkatze. Da in den bekannten Montagehaken keine Sicherung vorgesehen ist, besteht die Gefahr, dass bei unbeabsichtigten Absetzen oder Verkanten die Traverse mit dem zu kletternden Turmstück aus dem Montagehaken gedrückt wird und das Turmstück abstürzt.The traverse received with the mounting hook is transferred to an installation position to a mounting trolley, which is mounted on a mounting tower. The transfer of the tower section to be climbed to the mounting trolley by settling the crossbar in the mounting trolley. Since no backup is provided in the known mounting hook, there is a risk that in case of unintentional settling or tilting the traverse is pressed with the tower section to be climbed out of the mounting hook and the tower section crashes.
Für den Klettervorgang muss der Kran, insbesondere der Turmdrehkran, mit einem Ausgleichsgewicht an einem Lasthaken ausgeglichen werden, so dass der Schwerpunkt des Turmdrehkrans in einer Längsachse des Turmdrehkrans liegt. Dies ist notwendig, um ein Kippen des Krans und im schlimmsten Fall ein Umstürzen beim Klettervorgang zu vermeiden. In der Regel wird hierzu ein weiteres Turmstück mit einer Anschlagkette oder einem Schlupf am Lasthaken befestigt. Für das Befestigen muss der Lasthaken erneut nach unten fahren und ein Monteur hängt das Ausgleichsgewicht in den Lasthaken ein. Zum Klettern wird das Ausgleichsgewicht auf die Höhe des Führungsstücks angehoben und in die Ausgleichsposition gefahren. Nach dem Klettervorgang wird das Ausgleichsgewicht abgelassen und ausgehängt. Eine Unterflasche mit dem Montagehaken wird erneut nach oben gefahren.For the climbing process, the crane, in particular the tower crane, must be balanced with a balancing weight on a load hook, so that the center of gravity of the tower crane lies in a longitudinal axis of the tower crane. This is necessary to avoid tipping the crane and, in the worst case, overturning during climbing. As a rule, another tower section with a sling chain or a slippage is fastened to the load hook for this purpose. For attaching the load hook must drive down again and a fitter hangs the balancing weight in the load hook. For climbing, the balance weight is raised to the height of the guide piece and moved into the balancing position. After the climbing process, the balance weight is lowered and unhooked. A lower bottle with the mounting hook is moved up again.
Die
Die Aufgabe der vorliegenden Erfindung besteht daher darin, eine Vorrichtung zum Montieren und/oder Demontieren eines Krans vorzusehen, die wenigstens die zuvor genannten Nachteile nicht aufweist.The object of the present invention is therefore to provide a device for mounting and / or dismantling a crane, which does not have at least the aforementioned disadvantages.
Die Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is solved by the subject matter of
Erfindungsgemäß weist eine Vorrichtung zum Montieren oder Demontieren eines Krans, insbesondere eines Turmdrehkrans, eine Koppeleinheit zum Koppeln der Vorrichtung mit einem Träger eines Turmstücks auf. Die Koppeleinheit ist derart ausgebildet und angeordnet, dass diese in eine Verriegelungsstellung zum Vermeiden eines Lösens einer Kopplung der Koppeleinheit mit dem Träger des Turmstücks oder eine Entriegelungsstellung zum Koppeln oder Entkoppeln der Koppeleinheit mit dem Träger des Turmstücks überführt werden kann.According to the invention, a device for mounting or dismounting a crane, in particular a tower crane, has a coupling unit for coupling the device to a carrier of a tower section. The coupling unit is designed and arranged such that it can be transferred into a locking position for avoiding a release of a coupling of the coupling unit with the support of the tower section or an unlocking position for coupling or decoupling of the coupling unit with the support of the tower section.
Das Vorsehen einer Koppeleinheit mit einer Verriegelungsstellung bietet den Vorteil, dass ein Lösen der Kopplung des Trägers des Turmstücks mit der Koppeleinheit durch unbeabsichtigtes Absetzen oder Verkanten des Trägers sicher und einfach verhindert werden kann. Ein Lösen des Trägers von der Koppeleinheit kann nur dann erfolgen, wenn sich die Koppeleinheit in einer Entriegelungsstellung befindet. Foglich wird die Gefahr eines Absturz eines Turmstücks, beispielsweise bei einem fehlerhaften Aufsetzen auf die Montagelaufkatze, vermieden.The provision of a coupling unit with a locking position has the advantage that a release of the coupling of the carrier of the tower section with the coupling unit can be prevented safely and easily by unintentional settling or tilting of the carrier. A release of the carrier of the coupling unit can only be done when the coupling unit is in an unlocked position. Foglich, the risk of a crash of a tower piece, for example, in a faulty placement on the mounting trolley, avoided.
Als eine Koppeleinheit, die sich in einer Verriegelungsstellung befindet, wird im Sinne der Erfindung beispielsweise jegliches Bauteil oder Bauteile verstanden, das sicherstellt, dass sich der Träger des Turmstücks nicht von selbst von der Kopplung mit der Koppeleinheit lösen kann. Eine Lösung bzw. Entkopplung soll demnach nur möglich sein, wenn die Koppeleinheit in eine Entriegelungsstellung überführt wird. Als Entriegelungsstellung wird jeder Zustand der Koppeleinheit verstanden, bei der wenigstens ein Teil des Trägers und damit das Turmstück zum Koppeln mit der Koppeleinheit aufgenommen werden oder zum Entkoppeln mit der Koppeleinheit freigegeben wird.As a coupling unit, which is located in a locking position, for the purposes of the invention, for example, any component or components understood that ensures that the support of the tower section can not solve by itself from the coupling with the coupling unit. A solution or decoupling should therefore only be possible if the coupling unit is transferred into an unlocked position. As unlocking each state of the coupling unit is understood in which at least a portion of the carrier and thus the tower section are added for coupling with the coupling unit or released for decoupling with the coupling unit.
Weiter umfasst die Koppeleinheit einen, insbesondere drehfesten, Führungsabschnitt zum Führen von wenigstens einem Teil des Trägers, insbesondere eines Querbolzens des Trägers, des Turmstücks während eines Koppelvorgangs. Der Führungsabschnitt weist eine Einlaufschräge auf. Zudem weist die Koppeleinheit einen drehbaren Haken auf. Der Haken und der Führungsabschnitt sind mit einem Befestigungsabschnitt verbunden bzw. kann der Haken an dem Befestigungsabschnitt gelagert sein.Furthermore, the coupling unit comprises a, in particular rotationally fixed, guide section for guiding at least part of the carrier, in particular a transverse pin of the carrier, of the tower section during a coupling operation. The guide section has an inlet slope. In addition, the coupling unit has a rotatable hook. The hook and the guide portion are connected to a mounting portion and the hook can be mounted on the mounting portion.
Durch das Vorsehen des Führungsabschnitts, insbesondere des Führungsabschnitts mit der Einlaufschräge, kann sichergestellt werden, dass eine die Koppeleinheit, insbesondere der Führungsabschnitt, wenigstens einen Teil des Trägers kontaktiert. Foglich ist kein Monteur mehr notwendig, der die Koppeleinheit am Boden entsprechend führt.By providing the guide section, in particular the guide section with the inlet slope, it can be ensured that the coupling unit, in particular the guide section, at least part of the support contacted. Foglich no fitter is necessary, which leads the coupling unit on the ground accordingly.
Aufgrund des Vorsehens des Führungsabschnitts, insbesondere mit Einlaufschräge, wird wenigstens ein Teil des Trägers bei einem Absenken der Koppeleinheit mit dem Führungsabschnitt und dem Haken in Kontakt kommen. Bei einem weiteren Absenken der Koppeleinheit und/oder aufgrund des Eigengewichts des Hakens und/oder des Eigengewichts von weiteren an der Koppeleinheit vorgesehener Ausgleichsgewichte wird wenigstens ein Teil des Trägers, insbesondere ein Querbolzen, gegen den Haken gedrückt. Infolge der von dem Querbolzen auf den Träger ausgeübten Kraft dreht sich der Haken derart, dass sich die Koppeleinheit in einer Entriegelungsstellung befindet.Due to the provision of the guide section, in particular with inlet slope, at least a part of the carrier will come into contact with the guide section and the hook when the coupling unit is lowered. At another Lowering of the coupling unit and / or due to the dead weight of the hook and / or the dead weight of other provided on the coupling unit balancing weights at least a portion of the carrier, in particular a transverse pin, pressed against the hook. As a result of the force exerted by the cross bolt on the carrier, the hook rotates such that the coupling unit is in an unlocked position.
Der Träger, insbesondere der Querbolzen des Trägers, kann in einen Aufnahmeraum der Koppeleinheit eindringen. Nach einem Eindringen von wenigstens einem Teil des Trägers dreht sich der Haken wieder in die Verriegelungsstellung, wobei die Koppeleinheit mit dem Träger gekoppelt ist. Das Koppeln des Trägers mit der Koppeleinheit kann weiter vereinfacht werden, wenn an dem Haken eine entsprechende Führung für den Träger, insbesondere den Querbolzen, vorgesehen ist. Im Ergebnis bleibt festzuhalten, dass das Koppeln des Trägers und damit des Turmstücks mit der Koppeleinheit automatisch durch ein Absenken der Koppeleinheit erfolgt. Somit ist kein Monteur mehr für die Kopplung der Koppeleinheit mit dem auf dem Boden befindlichen Turmstück notwendig. Der Kranführer kann die Koppeleinheit einfach in Richtung zu dem Träger absenken.The carrier, in particular the transverse pin of the carrier, can penetrate into a receiving space of the coupling unit. After penetration of at least part of the carrier, the hook rotates back into the locking position, wherein the coupling unit is coupled to the carrier. The coupling of the carrier with the coupling unit can be further simplified if a corresponding guide for the carrier, in particular the transverse bolt, is provided on the hook. As a result, it should be noted that the coupling of the carrier and thus of the tower section with the coupling unit takes place automatically by lowering the coupling unit. Thus, no fitter is necessary for the coupling of the coupling unit with the tower piece located on the ground. The crane operator can simply lower the coupling unit in the direction of the carrier.
Der Haken kann mit einer Spanneinheit, wie beispielsweise einer Federeinrichtung, insbesondere einer Gasdruckfeder, gekoppelt sein. Die Spanneinheit kann für den Fall, dass der Träger und damit das Turmstück, insbesondere in eine Einbauposition, bewegt werden auf den Haken eine derartige Kraft ausüben, dass der Haken in der Verriegelungsstellung gehalten wird. Foglich wird durch das Vorsehen der Spanneinheit ein Lösen der Kopplung der Koppeleinheit mit dem Träger des Turmstücks wirksam verhindert.The hook may be coupled to a clamping unit, such as a spring device, in particular a gas spring. The clamping unit can, in the event that the carrier and thus the tower piece, in particular in an installed position, are moved on the hook exert a force such that the hook is held in the locking position. Foglich is effectively prevented by the provision of the clamping unit releasing the coupling of the coupling unit with the support of the tower section.
Der Haken kann derart ausgebildet sein, dass aufgrund der Eigengewichtskraft des Hakens und/oder der Gewichtskraft des mit dem Haken gekoppelten Trägers und damit des Turmstücks auf den Haken ein Drehmoment wirkt. Dieses Drehmoment ist derart gerichtet, dass es den Haken in der Verriegelungsstellung hält. Dadurch kann auf einfache Weise ein sicheres Transportieren des Trägers und der Turmstücke, beispielsweise in die Einbauposition, erzielt werden.The hook can be designed such that due to the self-weight force of the hook and / or the weight of the hook coupled to the carrier and thus the tower piece acts on the hook torque. This torque is directed to hold the hook in the locked position. Thereby can be achieved in a simple manner, a safe transporting the carrier and the tower pieces, for example in the installed position.
In einer bevorzugten Ausführung kann die Koppeleinheit ein Übertragungsmittel aufweisen. Das Übertragungsmittel kann boomerangförmig ausgebildet sein und drehbar an dem Befestigungsabschnitt der Koppeleinheit angeordnet sein. Dabei können die Drehachsen des Hakens und des Übertragungsmittels koinzident sein. Ferner kann das Übertragungsmittel mit der Spanneinheit, insbesondere einer Gasdruckfeder, insbesondere unmittelbar, gekoppelt sein. Zudem kann das Übertragungsmittel mit dem Haken gekoppelt sein. Die Kopplung des Übertragungsmittels mit dem Haken kann durch ein auf dem Haken angeordnetes Koppelmittel, wie beispielsweise einen Zapfen, erfolgen.In a preferred embodiment, the coupling unit may have a transmission means. The transmission means may be formed boomerangförmig and rotatably disposed on the attachment portion of the coupling unit. The axes of rotation of the hook and the transmission means can be coincident. Furthermore, the transmission means with the clamping unit, in particular a gas spring, in particular directly coupled. In addition, the transmission means may be coupled to the hook. The coupling of the transmission means with the hook can be done by a hook arranged on the coupling means, such as a pin.
Dabei ist ein Anlenkpunkt der Spanneinheit mit dem Übertragungsmittel derart vorgesehen, dass bei einer Bewegung des Turmstücks in die Einbauposition die Spanneinheit eine derartige Kraft auf das Übertragungsmittel ausübt, dass ein erster Schenkel mit dem Koppelmittel des Hakens unmittelbar in Kontakt ist. Infolge der Kopplung der ersten Schenkel mit dem Koppelmittel des Hakens wirkt auf diesen ein Drehmoment, dass den Haken und damit die Koppeleinheit in einer Verriegelungsstellung hält. Folglich kann ein einfacher Aufbau der Koppeleinheit zum Halten des Hakens in einer Verriegelungsstellung vorgesehen werden.In this case, a pivot point of the clamping unit is provided with the transmission means such that upon movement of the tower section in the installation position, the clamping unit exerts such force on the transmission means that a first leg is in direct contact with the coupling means of the hook. As a result of the coupling of the first leg with the coupling means of the hook acting on this torque that holds the hook and thus the coupling unit in a locking position. Consequently, a simple construction of the coupling unit for holding the hook can be provided in a locking position.
Das Übertragungsmittel kann an einem Ende, insbesondere an einem Ende eines zweiten Schenkels, ein Verbindungsmittel aufweisen, das mit einer Betätigungsstange koppelbar ist. Durch ein Koppeln der Betätigungsstange mit dem Verbindungsmittel beispielsweise durch einen Benutzer kann das Übertragungsmittel gedreht werden. Die Betätigung mit der Betätigungsstange kann erfolgen, wenn sich das Turstück in der Einbaupostion befindet und dient zum Überführen der Koppeleinheit in die Entriegelungsstellung. Die Drehung des Übertragungsmittels erfolgt dabei derart, dass der zweite Schenkel in Richtung zum Koppelmittel des Hakens gedreht wird. Bei einem Anstoßen des zweiten Schenkels gegen das Koppelmittels und einem weiter Drehen des Übertragungsmittels in die gleiche Richtung wird der Haken in eine Entriegelungsstellung gedreht. Vor einem Anstoßen des zweiten Schenkels gegen das Koppelmittel wird der Haken nicht gedreht.The transmission means may comprise at one end, in particular at one end of a second leg, a connection means which can be coupled to an actuating rod. By coupling the operating rod to the connecting means, for example by a user, the transmission means can be rotated. The actuation with the actuating rod can be done when the door piece is in the installation station and serves to transfer the coupling unit in the unlocked position. The rotation of the transmission means takes place in such a way that the second leg is rotated in the direction of the coupling means of the hook. Upon abutment of the second leg against the coupling means and a further rotation of the transmission means in the same direction is the Hook turned into an unlocked position. Prior to abutment of the second leg against the coupling means of the hook is not rotated.
Bei einer Betätigung des Übertragungsmittel mittels der Betätigungsstange kann der Haken soweit gedreht werden, dass er in der Entriegelungsstellung gehalten wird. Dies ist, weil das Übertragungsmittel und somit der Anlenkpunkt zwischen Übertragungsmittel und Spanneinheit, insbesondere der Federeinrichtung, soweit gedreht werden, dass auf das Übertragungsmittel und damit auf den Haken ein Drehmoment wirkt, das den Haken und damit die Koppeleinheit in der Entriegelungsstellung hält. Hingegen dreht sich beim zuvor beschriebenen Koppeln des wenigstens einen Teils des Trägers mit der Koppeleinheit aufgrund des Absenkens der Koppeleinheit und/oder des Eigengewichts der Koppeleinheit der Anlenkpunkt zwischen dem Übertragungsmittel und der Spanneinheit nur soweit, dass durch die Spanneinheit auf das Übertragungsmittel und damit den Haken ein Drehmoment bewirkt wird, das den Haken in die Verriegelungsstellung drängt.Upon actuation of the transmission means by means of the actuating rod, the hook can be turned so far that it is held in the unlocked position. This is because the transmission means and thus the point of articulation between the transmission means and the tensioning unit, in particular the spring means, are turned so far that acts on the transmission means and thus on the hook a torque which holds the hook and thus the coupling unit in the unlocked position. On the other hand, in the previously described coupling of the at least one part of the carrier with the coupling unit due to the lowering of the coupling unit and / or the dead weight of the coupling unit, the pivot point between the transmission means and the clamping unit rotates only to the extent that by the clamping unit on the transmission means and thus the hook a torque is caused which urges the hook in the locking position.
Dabei kann eine Betätigung des Übertragungsmittels nur dann erfolgen, wenn auf den Haken keine Last wirkt. Dies kann dann der Fall sein, wenn der Träger fehlerfrei beispielsweise auf die Montagelaufkatze aufgesetzt wird. Somit kann durch das Betätigen des Übertragungsmittels auf einfache Weise ermittelt werden, ob der Träger fehlerfrei aufgesetzt ist.In this case, an actuation of the transmission means only take place when no load acts on the hook. This may be the case when the carrier is placed without error, for example, on the mounting trolley. Thus, it can be determined by operating the transmission means in a simple manner, whether the carrier is placed correctly.
Gemäß einem anderen Aspekt der Erfindung weist eine Vorrichtung zum Montieren oder Demontieren eines Krans, insbesondere eines Turmkrans, eine Koppeleinheit zum Koppeln der Vorrichtung mit einem Turmstück auf. Die Vorrichtung kann alle zuvor genannten Merkmale aufweisen. Die Koppeleinheit weist wenigstens ein Ausgleichsgewicht zum Einstellen eines Schwerpunkts des Krans auf. Das Ausgleichsgewicht kann in eine Ausgleichsposition, insbesonder beim Klettern des Krans, bewegbar sein. Dies kann beispielsweise durch eine horizontale und/oder vertikale Bewegung des Ausgleichsgewichts erfolgen.According to another aspect of the invention, a device for mounting or dismounting a crane, in particular a tower crane, has a coupling unit for coupling the device to a tower section. The device may have all the aforementioned features. The coupling unit has at least one balance weight for setting a center of gravity of the crane. The balance weight may be movable to a balancing position, especially when climbing the crane. This can be done for example by a horizontal and / or vertical movement of the balance weight.
Der Vorteil in dem Vorsehen eines Ausgleichsgewichts in der Koppeleinheit besteht darin, dass es nicht mehr, wie im Stand der Technik, notwendig ist, die Koppeleinheit zum Koppeln mit dem Ausgleichsgewicht abzusenken, um das auf dem Erdboden befindliche Ausgleichsgewicht aufzunehmen. Vielmehr kann das Ausgleichsgewicht ohne Absenken der Koppeleinheit gleich in eine Ausgleichsposition bewegt werden. Der Ausgleich erfolgt durch das integrierte Ausgleichsgewicht an dem Haken. Dies führt zu einer erheblichen Zeiteinsparung.The advantage in providing a balance weight in the coupling unit is that it is no longer necessary, as in the prior art, to lower the coupling unit for coupling with the balance weight to accommodate the ground level balance weight. Rather, the balance weight can be moved without lowering the coupling unit equal to a balancing position. The compensation is made by the integrated balance weight on the hook. This leads to a considerable time saving.
Der Haken kann mit dem Ausgleichsgewicht gekoppelt sein. Insbesondere kann der Befestigungsabschnitt mit dem Ausgleichsgewicht verbunden sein.The hook can be coupled with the balance weight. In particular, the attachment portion may be connected to the balance weight.
Die erfindungsgemäße Vorrichtung kann zum Montieren oder Demontieren eines Turmdrehkrans eingesetzt werden.
