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 GB 861 037 A zeigt eine herkömmliche Vorrichtung zum Montieren oder Demontieren eines Krans, bei der der zu hebende Mastschuss mit Hilfe einer Ausgleichseinheit innerhalb der Minimalauslegerspannweite des Krans befördert werden kann.The GB 861 037 A shows a conventional device for mounting or dismounting a crane, in which the mast shot to be lifted can be conveyed by means of a compensation unit within the minimum boom span of the crane.

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 claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Nach einem Beispiel 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 one example, a device for mounting or dismounting a crane, in particular a tower crane, has a coupling unit for coupling the device to a support of a tower section. The coupling unit is designed and arranged such that it is in a locking position for avoiding a release of a coupling of the coupling unit with the support of the tower section or an unlocked position for coupling or decoupling the coupling unit with the carrier of the tower piece can be transferred.

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.

In einem bevorzugten Beispiel kann die Koppeleinheit einen, insbesondere drehfesten, Führungsabschnitt zum Führen von wenigstens einem Teil des Trägers, insbesondere eines Querbolzens des Trägers, des Turmstücks während eines Koppelvorgangs aufweisen. Der Führungsabschnitt kann eine Einlaufschräge aufweisen. Zudem kann die Koppeleinheit einen drehbaren Haken aufweisen. Der Haken und der Führungsabschnitt können mit einem Befestigungsabschnitt verbunden sein bzw. der Haken kann an dem Befestigungsabschnitt gelagert sein.In a preferred example, the coupling unit may have 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 portion may have an inlet slope. In addition, the coupling unit may have a rotatable hook. The hook and the guide portion may be connected to a mounting portion and the hook may 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. In a further 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 is 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 such a force that the hook is held in the locked 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. As a result, a safe transport of the carrier and the tower pieces, for example, in the installed position, can be achieved in a simple manner.

In einem weiteren bevorzugten Beispiel 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 further preferred example, 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 take place when the door piece is located 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 further rotation of the transmission means in the same direction, the hook is rotated to 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 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 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 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 coupling unit has at least one balance weight for setting a center of gravity of the crane. The balance weight can be in a compensation position, in particular when climbing the crane to be movable. 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. Natürlich können auch weitere Krane mit der erfindungsgemäßen Vorrichtung montiert bzw. demontiert werden.The device according to the invention can be used for mounting or dismounting a tower crane. Of course, other cranes can be mounted or dismounted with the device according to the invention.

Weitere Einzelheiten und Vorteile der Erfindung sollen nun anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden.Further details and advantages of the invention will now be explained in more detail with reference to an embodiment shown in the drawing.

Die in Figur 1 gezeigte Vorrichtung zum Montieren und Demontieren eines in den Figuren nicht gezeigten Krans, insbesondere eines Turmdrehkrans. Die Vorrichtung weist einen Montageturm 10 und eine mit dem Montageturm 10 verbundene Koppeleinheit 11 auf. Die Koppeleinheit 11 ist mit dem Träger 2 gekoppelt, wobei der Träger 2 ein zu kletterndes Turmstück 3 trägt. Zum Montieren kann das Turmstück 3 über eine in dem Montageturm 10 vorgesehene Öffnung 12 in diesen eingebracht und mit einem in den Figuren nicht dargestellten Turm verbunden werden. Das Einführen des Turmstücks in die Öffnung kann durch eine Montagelaufkatze 13 erfolgen, ist jedoch nicht darauf beschränkt. Ein Demontieren des Turms kann in umgekehrter Reihenfolge wie das Montieren erfolgen, so dass sich die nachfolgenden Aussagen nur auf das Montieren des Turms beziehen.In the FIG. 1 shown device for mounting and dismounting of a crane, not shown in the figures, in particular a tower crane. The device has a mounting tower 10 and a coupling unit 11 connected to the mounting tower 10. The coupling unit 11 is coupled to the carrier 2, wherein the carrier 2 carries a tower section 3 to be climbed. For mounting the tower section 3 can be introduced via an opening provided in the mounting tower 10 opening 12 in this and connected to a tower, not shown in the figures. The insertion of the tower piece into the opening can be done by a mounting trolley 13, but is not limited thereto. Dismantling of the tower can be done in reverse order as the mounting, so that the following statements refer only to the mounting of the tower.

Wie aus Figur 2 ersichtlich ist, weist der Träger 2 einen Längsrahmen 24 auf, an desen Ende sich jeweils erste Vorsprünge 26 erstrecken. Die Vorsprünge 26 definieren einen Aufnahmeraum 23, in das ein in der Figur 2 nicht dargestellter Teil des Turmstücks 3 eindringt. Der Aufnahmeraum 23 wird durch einen Bolzen 22 begrenzt. Ferner weist der Träger 2 einen zweiten Vorsprung 20 auf, der sich von dem Längsrahmen 24 in die entgegengesetzte Richtung wie die Vorsprünge 26 erstrecken. In einem von dem Längsrahmen 21 entfernten Ende des Vorsprungs 20 ist ein Querbolzen 21 vorgesehen.How out FIG. 2 it can be seen, the carrier 2 has a longitudinal frame 24, at the end of each first projections 26 extend. The projections 26 define a receiving space 23, in which a in the FIG. 2 not shown part of the tower section 3 penetrates. The receiving space 23 is limited by a bolt 22. Further, the carrier 2 has a second projection 20 which extend from the longitudinal frame 24 in the opposite direction as the projections 26. In a remote from the longitudinal frame 21 end of the projection 20, a transverse pin 21 is provided.

Ferner wird in Figur 2 ein Teil der Koppeleinheit 11 dargestellt. So weist die Koppeleinheit 11 ein Ausgleichsgewicht 110 auf. Ferner weist die Koppeleinheit 11 einen schwenkbaren Haken 112 und einen Führungsabschnitt 114 mit einer Einlaufschräge auf. Der Führungsabschnitt 114 weist an einem Ende der Einlaufschräge eine Aufnahmenut 113 auf. Der Führungsabschnitt 114 und der Haken 112 sind mit dem Befestigungsabschnitt 111 befestigt. Dabei ist der Haken 112 drehbar mit dem Befestigungsabschnitt 111 und der Führungsabschnitt 114 drehfest mit dem Befestigungsabschnitt 111 verbunden. Der Befestigungsabschnitt 111 wiederum kann mit dem Ausgleichsgewicht 110 verbunden sein.Further, in FIG. 2 a part of the coupling unit 11 is shown. Thus, the coupling unit 11 has a balance weight 110. Furthermore, the coupling unit 11 has a pivotable hook 112 and a guide portion 114 with an inlet slope. The guide section 114 has a receiving groove 113 at one end of the inlet slope. The guide portion 114 and the hook 112 are with attached to the attachment portion 111. In this case, the hook 112 is rotatably connected to the attachment portion 111 and the guide portion 114 rotatably connected to the mounting portion 111. The attachment portion 111 in turn may be connected to the balance weight 110.

Wie aus der Figur 3A ersichtlich ist, weist die Koppeleinheit 11 an zwei sich gegenüber einer Mittelachse M der Koppeleinheit 11 gegenüberliegenden Seiten jeweils einen Haken auf. An jeder Seite der Koppeleinheit 11 können meherere Ausgleichsgewichte 110 angeordnet sein. Die Querbolzen 21 ragen in einen Raum, der sich zwischen den Vorsprüngen 20 des Trägers 2 ausbildet. Dabei wird der Träger 2 über den nach innen ragenden Teil der Querbolzen 21 bei einem Aufsetzen des Trägers 2 an die Montagelaufkatze 13 mit dieser unmittelbar gekoppelt.Like from the FIG. 3A it can be seen, the coupling unit 11 at two opposite to a central axis M of the coupling unit 11 opposite sides each have a hook. On each side of the coupling unit 11, several balance weights 110 may be arranged. The transverse pins 21 protrude into a space that forms between the projections 20 of the carrier 2. In this case, the carrier 2 is coupled via the inwardly projecting part of the transverse pin 21 at a touch of the carrier 2 to the mounting trolley 13 with this directly.

In Figur 3B ist der Zustand dargestellt, bei dem der Querbolzen 21 des Trägers 2 mit der Einlaufschräge des Führungsabschnitts 114 und dem Haken 112 in Kontakt ist. Dieser Zustand der Koppeleinheit stellt sich bei einem Absenken der Koppeleinheit 11 ein, um dieses mit einem auf dem Boden befindlichen Turmstück 3 bzw. Träger 2 zu koppeln. Die Koppeleinheit 11 befindet sich dabei noch immer in der Verriegelungsstellung. Dabei ist eine Federeinrichtung 117, insbesondere eine Gasdruckfeder vorgesehen, die den Haken 112 in der Verriegelungsstellung hält.In FIG. 3B the state is shown in which the cross pin 21 of the carrier 2 with the inlet slope of the guide portion 114 and the hook 112 in contact. This state of the coupling unit adjusts itself to a lowering of the coupling unit 11 in order to couple it to a tower section 3 or support 2 located on the floor. The coupling unit 11 is still in the locked position. In this case, a spring device 117, in particular a gas pressure spring is provided which holds the hook 112 in the locked position.

Diesbezüglich weist die Koppeleinheit 11 ein an dem Befestigungsabschnitt 111 drehbar angeordnetes Übertragungsmittel 116 auf, das mit der Federeinrichtung 117, in einem Anlenkpunkt, insbesondere unmittelbar, gekoppelt ist. Ferner ist das Übertragungsmittel116 über einen ersten Schenkel 116' mit einem ersten Koppelmittel 118, wie beispielsweise einem Zapfen, des Hakens 112, insbesondere unmittelbar, gekoppelt. Dabei wirkt die Federeinrichtung 117 derart auf das Übertragungsmittel, dass der Haken 112 in der Verriegelungsstellung gehalten wird. Genauer gesagt bewirkt die über den Anlenkpunkt 115 eingeleitete Kraft de R Federeinrichtung eine Drehmoment und damit eine Drehung des Übertragungsmittels in Richtung U. Die Drehung ist derart gerichtet, dass durch den ersten Schenkel 116' des Übertragungsmittels und das Koppelmittel 118 der Haken 112 in der Verriegelungsstellung gehalten wird.In this regard, the coupling unit 11 has a transmission means 116 which is rotatably arranged on the fastening section 111 and which is coupled to the spring device 117 in a pivot point, in particular directly. Furthermore, the transmission means 116 is coupled via a first leg 116 'to a first coupling means 118, such as a pin, of the hook 112, in particular directly. In this case, the spring device 117 acts on the transmission means such that the hook 112 is held in the locking position. More specifically, the force applied via the pivot point 115 force de R spring means causes a torque and thus a rotation of the transmission means in direction U. The rotation is directed such that through the first Leg 116 'of the transmission means and the coupling means 118 of the hook 112 is held in the locking position.

Bei einem Aufsetzen der Koppeleinheit 11, insbesondere des Hakens 112 auf den Querbolzen 21 wird infolge des Eigengewichts der Ausgleichsgewichte 110 der Haken 112 gedreht, insbesondere aufgedrückt, wie aus Figur 4B ersichtlich ist. Dabei zeigt Figur 4B den Haken 112 und damit die Koppeleinheit in einer Entriegelungsstellung. Der in Figur 4B dargestellte Zustand bildet sich dann aus, wenn die Koppeleinheit ausgehend von dem in Figur 3B dargestellten Zustand weiter abgesenkt wird, so dass die Gewichtskraft der Ausgleichsgewichte nicht mehr durch die Vorrichtung, insbesondere Seile der Vorrichtung, aufgenommen wird. Der Haken 112 dreht sich in Richtung H und die Drehbewegung des Hakens 112 wird über die Koppelstelle 118 auf das Übertragungsmittel 116 übertragen, wodurch sich dieses ebenfalls in die gleiche Richtung dreht. Im Ergebnist dringt der Querbolzen 21 in einen Raum zwischen dem Haken 112 und der Einlaufschräge des Führungsabschnitts 114 ein. Das Eindringen wird dabei durch eine am Haken 112 vorgesehene Führung und die Einlaufschräge des Führungsabschnitts 114 begünstigt.When placing the coupling unit 11, in particular of the hook 112 on the transverse pin 21 is due to the dead weight of the balance weights 110 of the hook 112 is rotated, in particular pressed, as from FIG. 4B is apparent. It shows FIG. 4B the hook 112 and thus the coupling unit in an unlocked position. The in FIG. 4B shown state is formed when the coupling unit starting from the in FIG. 3B shown state is further lowered, so that the weight of the balance weights is no longer absorbed by the device, in particular ropes of the device. The hook 112 rotates in the direction of H and the rotational movement of the hook 112 is transmitted via the coupling point 118 to the transmission means 116, whereby this also rotates in the same direction. As a result, the cross pin 21 penetrates into a space between the hook 112 and the inlet slope of the guide portion 114. The penetration is promoted by a provided on the hook 112 guide and the inlet slope of the guide portion 114.

Nach einem in Figur 5B vollständigen Eindringen des Querbolzens 21 in die Koppeleinheit 11 aufgrund des weiteren Absenkens der Koppeleinheit 11 und/oder aufgrund des Eigengewichts der Ausgleichsgewichte 112 schnappt der Haken 112 zurück und die Koppeleinheit 11 befindet sich wieder in der Verriegelungsstellung. Dabei befindet sich der Querbolzen 21 in der Aufnahmenut 113 des Führungsabschnitts 114. Das Zurückschnappen des Hakens wird dadurch bewirkt, dass durch die Federeinrichtung 117 über den Anlenkpunkt 115 ein Kraft auf das Übertragungsmittel 116 wirkt. Diese Kraft bewirkt eine Drehmoment und damit eine Drehung des Übertragungsmittels 116 in Richtung U. Die Drehung des Übertragungsmittels 116 wird über das Koppelmittel 118 auf den Haken 112 übertragen, wobei die Drehung derart gerichtet ist, dass der Haken 112 in die Verriegelungsstellung gedrückt wird.After a in FIG. 5B complete penetration of the transverse pin 21 in the coupling unit 11 due to the further lowering of the coupling unit 11 and / or due to the dead weight of the balance weights 112 snaps the hook 112 back and the coupling unit 11 is again in the locked position. In this case, the transverse pin 21 is in the receiving groove 113 of the guide portion 114. The snap back of the hook is effected by the spring means 117 via the pivot point 115, a force acting on the transmission means 116. This force causes a torque and thus a rotation of the transmission means 116 in the direction U. The rotation of the transmission means 116 is transmitted via the coupling means 118 on the hook 112, wherein the rotation is directed such that the hook 112 is pressed into the locking position.

Beim in Figur 6B dargestellten Bewegen der Koppeleinheit 11 und damit des mit der Koppeleinheit 11 verbundenen Trägers 2 in eine Richtung R weg von dem Erdboden befindet sich der Querbolzen 21 in einem entsprechend ausgebildeten Aufnahmebereiech des Hakens 112. Dabei ist der Aufnahmebereich des Hakens 112 derart ausgebildet, dass die Gewichtskraft des Trägers 2 und des damit getragenen Turmstücks ein Drehmoment um eine Drehachse 120 des Hakens 112 bewirken, das derart gerichtet ist, dass der Haken 112 in der Verriegelungsstellung gehalten wird.When in FIG. 6B Moving the coupling unit 11 and thus of the carrier 2 connected to the coupling unit 11 in a direction R away from the ground, the transverse pin 21 is in a correspondingly trained Aufnahmebereiech the hook 112. The receiving portion of the hook 112 is formed such that the weight the carrier 2 and the tower piece carried therewith cause a torque about an axis of rotation 120 of the hook 112, which is directed so that the hook 112 is held in the locking position.

Bei der in den Figuren 7A und 7B dargestellten Stellung befindet sich die Koppeleinheit 11 und damit das Turmstück in der gewünschten Höhe über dem Erdboden. Ferner ist der Träger 2 auf der Montagelaufkatze 13 abgesetzt und befindet sich daher in der Einbauposition. In diesem Fall werden die Haken 112 nicht mehr mit Last beansprucht. Des Weiteren befindet sich bei dieser Stellung der Koppeleinheit 11 der Querbolzen 21 in der Aufnahmenut 113 des Führungsabschnitts.In the in the FIGS. 7A and 7B illustrated position is the coupling unit 11 and thus the tower section in the desired height above the ground. Further, the carrier 2 is set down on the mounting trolley 13 and is therefore in the installed position. In this case, the hooks 112 are no longer stressed with load. Furthermore, in this position, the coupling unit 11 of the transverse pin 21 is located in the receiving groove 113 of the guide section.

Ferner wird in in Figur 7B eine Betätigungsstange 4 gezeigt, die mit einem Verbindungsmittel 119 eines zweiten Schenkels 116" des Übertragungsmittels 116 gekoppelt ist. Das Verbindungsmittel 119 ist an dem Ende des zweiten Schenkels 116" angeordnet. Das Übertragungsmittel 116 wird bei einer Bewegung der Betätigungsstange in Richtung B derart in Richtung U gedreht, dass sich das Verbindungsmittel 119 des zweiten Schenkels 116' in Richtung zum Koppelmittel 118 des Hakens 112 bewegt.Further, in in FIG. 7B an actuating rod 4 which is coupled to a connecting means 119 of a second leg 116 "of the transmission means 116. The connecting means 119 is arranged at the end of the second leg 116". The transmission means 116 is rotated in a direction of movement of the actuating rod in the direction B in such a direction that the connecting means 119 of the second leg 116 'moves in the direction of the coupling means 118 of the hook 112.

In den Figuren 9A und 9b wird der Zustand des Übertragungsmittels 116 dargestellt, bei dem das Ende 119 des zweiten Schenkels 116" in Kontakt mit dem Koppelmittel 118 steht. Bei einer Drehung des Übertragungsmittels 116 von dem in den Figuren 7A und 7B dargestellten Zustand in den in den Figuren 8A und 8B dargestellten Zustand dreht sich der Haken 112 nicht.In the Figures 9A and 9B 1, the state of the transmission means 116 is shown, in which the end 119 of the second leg 116 "is in contact with the coupling means 118. Upon rotation of the transmission means 116 from the in the FIGS. 7A and 7B shown state in the in the Figures 8A and 8B illustrated state, the hook 112 does not rotate.

Dieser dreht sich erst, wenn das Übertragungsmittel 116 ausgehend von der in den Figuren 8A und 8B dargestellten Position weiter in Richtung U gedreht bzw. die Betätigungsstange weiter in Richtung B betätigt wird. Bei der in den Figuren 9A und 9B dargestellten Entriegelungsstellung der Koppeleinheit kann der Träger 2 von der Koppeleinheit 11 gelöst und beispielsweise über die Montagelaufkatze verfahren werden.This rotates only when the transmission means 116, starting from the in the Figures 8A and 8B shown position further rotated in the direction U or the Actuating rod is further actuated in the direction of B. In the in the Figures 9A and 9B illustrated unlocking position of the coupling unit, the carrier 2 can be solved by the coupling unit 11 and, for example, moved over the mounting trolley.

Bei der in Figur 10A und 10B dargestellten Stellung ist das Übertragungsmittel 116 und damit der Anlenkpunkt 115 soweit gedreht worden, dass die von der Federeinrichtung 117 in das Übertragungsmittel bewirkte Kraft ein Drehmoment und damit ein Drehung des Übertragungsmittels 116 in Richtung U bewirkt, dass über den zweiten Schenkel 116" und das Koppelmittel 118 den Haken 112 in eine Entriegelungsstellung dreht und hält. Der Haken 112 bleibt auch in der Entriegelungsstellung und dreht sich nicht selbsttätig in die Verriegelungsstellung zurück.At the in FIGS. 10A and 10B shown position, the transmission means 116 and thus the pivot point 115 has been rotated so far that caused by the spring device 117 in the transmission means force causes a torque and thus rotation of the transmission means 116 in the direction U, that on the second leg 116 "and the coupling means 118 rotates and holds the hook 112 in an unlocked position The hook 112 also remains in the unlocked position and does not automatically return to the locked position.

Vor einem Aufnehmen eines nächsten Trägers 2 mittels der Koppeleinheit 11 muss der Haken 112 durch den Benutzer in die in Figur 2 dargestellte Position zurückgestelllt werden, in der die Federeinrichtung 117 den Haken in der Verriegelungsstellung hält. Das Zurückstellen kann beispielsweise über die Betätigungsstange 4 erfolgen, wobei diese in eine Richtung betätigt wird, die entgegengesetzt zur Richtung B ist.Before picking up a next carrier 2 by means of the coupling unit 11, the hook 112 must be inserted by the user in the in FIG. 2 shown position zurückgestelllt in which the spring means 117 holds the hook in the locked position. The reset can be done for example via the actuating rod 4, wherein this is actuated in a direction opposite to the direction B is.
