Description

Die Erfindung betrifft eine Klettereinrichtung zum Einsetzen und Entfernen von Turmstücken bzw. aus Türmen von Turmdrehkranen, Arbeitsbühnen o. dgl.,
bestehend aus einem an das zu hebende oder abzusenkende Teil, beispielsweise ein Kranoberteil, einen Bühnensockel oder ein Turmstück, anbaubaren, ein Führungsstück bildenden und den Turm einfassenden Kletterrahmen mit einer zumindest teilweise offenen Einschubseite,
mit einer an einem Querstab des Stabverbandes angelenkten hydraulischen Presse, deren Kolbenstange einen Pressenschub mit einer auf den Eckstielen eines Turmstücks abstützbaren Klettertraverse trägt, und
mit einer an dem Querstab angelenkten Stütze mit einer auf Eckstielen abstützbaren Stütztraverse und einem endseitigen Stützschuh.The invention relates to a climbing device for inserting and removing tower pieces or from towers of tower cranes, working platforms or the like.
consisting of a part to be lifted or lowered on the part to be lifted or lowered, for example a crane upper part, a stage base or a tower section, forming a guide piece and enclosing the tower with an at least partially open insertion side,
with a hydraulic press articulated on a crossbar of the rod assembly, the piston rod of which carries a press thrust with a climbing traverse which can be supported on the corner posts of a tower section, and
with a support articulated on the crossbar with a support cross-piece that can be supported on corner posts and an end-side support shoe.

Klettereinrichtungen dieser Art werden üblicherweise an Turmdrehkränen verwendet, deren die Kranoberteile tragenden Türme je nach Baufortschritt in Abständen durch den Einbau eines Turmstücks verlängert werden müssen. Beim Abbau der Turmdrehkräne ist es dann umgekehrt wieder erforderlich, das Kranoberteil durch Ausbau einzelner Turmstücke abzusenken. Zum Ein- und Ausbau von Turmstücken sind Klettereinrichtungen der eingangs angegebenen Art bekannt. Um das Kranoberteil oder ein Turmstück zum Einbau eines Turmstücks zu heben, wird der Kletterrahmen an der Basis des Kranoberteils, beispielsweise der Kugeldrehkranzauflage, oder dem unteren Ende des zu hebenden Turmstücks befestigt, wobei die Verbindung des Kranoberteils zu dem nächst folgenden Turmstück oder die Verbindung zwischen den beiden Turmstücken gelöst wird. Sodann wird das Kranoberteil oder das geLöste Turmstück schrittweise durch Anheben des Kletterrahmens gehoben, bis ein neues Turmstück durch die offene Seite des Kletterrahmens eingesetzt werden kann, das dann in üblicher Weise mit dem Kranoberteil und/oder dem oder den Turmstücken verbunden werden kann. Zum Heben wird der Pressenschuh mittig auf den oberen Querstab eines Kletterverbandes des Turmstücks abgesenkt, wobei sich die mit dem Pressenschuh verbundene Klettertraverse auf den Eckstielen des Turmstücks abstützt, so daß der Querstab nur in vertikaler Richtung belastet wird und die Horizontalkräfte über die Klettertraverse in die Eckstiele eingeleitet werden. Der Kletterverband der Turmstücke besteht jeweils aus einem oberen Querstab mit mittlerem Knotenpunkt, in dem sich die oberen Enden zweier Diagonalstäbe treffen, deren unteren Enden an den Enden des nächstfolgenden unteren Querstabes im Bereich der Eckstiele angelenkt bzw. befestigt sind. Nach dem Heben des Kletterrahmens um einen Schritt fällt der Stützschuh der Stütze ein und stützt sich auf dem Querstab des Kletterverbandes ab, nachdem die Presse etwas eingefahren ist, so daß der Stützschuh auf dem Querstab fest zur Anlage kommt. Die mit der Stütze verbundene Quertraverse stützt sich auf den Eckstielen des Kletterrahmens ab, so daß der Querstab des Kletterverbandes des Turmstücks wiederum nur Vertikalkräfte und keine horizontalen Stützkräfte aufnehmen muß. Sobald der Stützschuh auf dem Querstab fest zur Auflage gekommen ist, kann die hydraulische Presse eingefahren werden, so daß sich der Pressenschuh zum Hub des nächsten Schrittes auf den nächst höheren Querstab auflegen kann.Climbing devices of this type are usually used on tower cranes, the towers of which support the upper crane parts, depending on the construction progress, have to be extended at intervals by installing a tower section. Conversely, when dismantling the tower cranes, it is again necessary to lower the upper crane part by removing individual tower sections. Climbing devices of the type specified at the outset are known for installing and removing tower sections. In order to lift the upper crane part or a tower section to install a tower section, the climbing frame is attached to the base of the upper crane part, for example the slewing ring support, or the lower end of the tower section to be lifted, the connection of the upper crane part to the next following tower section or the connection between the two tower sections is released. Then the upper part of the crane or the released tower section is lifted gradually by lifting the climbing frame until a new tower section can be inserted through the open side of the climbing frame, which can then be connected in the usual way to the upper crane section and / or the tower section or sections. For lifting, the press shoe is lowered in the middle onto the upper crossbar of a climbing association of the tower section, the climbing crossbar connected to the press shoe being supported on the corner posts of the tower section, so that the crossbar is only loaded in the vertical direction and the horizontal forces are via the climbing crossbar into the corner posts be initiated. The climbing structure of the tower sections consists of an upper crossbar with a central node, where the upper ends of two diagonal bars meet, the lower ends of which are articulated or fastened to the ends of the next lower crossbar in the area of the corner posts. After lifting the climbing frame by one step, the support shoe of the support collapses and is supported on the crossbar of the climbing association after the press has been retracted somewhat, so that the support shoe comes to rest firmly on the crossbar. The crossbar connected to the support is supported on the corner posts of the climbing frame, so that the crossbar of the climbing association of the tower section in turn only has to absorb vertical forces and no horizontal supporting forces. As soon as the support shoe has come to rest firmly on the crossbar, the hydraulic press can be retracted so that the press shoe can lay on the next higher crossbar to lift the next step.

Die Ausgestaltung und die Arbeitsweise der eingangs beschriebenen Klettereinrichtung ist beispielsweise aus dem Liebherr-Prospekt "Die großen HC-Krane", LBC-0181-A-01/90-2.d sowie die zu den HC-Kranen gehörige Betriebsanleitung bekannt.The design and mode of operation of the climbing device described at the outset is known, for example, from the Liebherr brochure "The large HC cranes", LBC-0181-A-01 / 90-2.d and the operating instructions belonging to the HC cranes.

Die bekannte Klettereinrichtung ist für die Klettertürme üblicher Drehkräne ausreichend. Werden die Klettertürme bzw. die zu hebenden Kranoberteile jedoch größer und schwerer, können die Abstützkräfte der Stützschuhe sowie der Pressenschuhe der Stützen und hydraulischen Pressen so groß werden, daß Verformungen der Querstäbe der Kletterverbände zu befürchten sind.The known climbing device is sufficient for the climbing towers of conventional rotating cranes. However, if the climbing towers or the upper crane parts to be lifted are larger and heavier, the support forces of the support shoes and the press shoes of the supports and hydraulic presses can become so great that deformations of the crossbars of the climbing associations can be feared.

Besonders schwere, große und hohe Türme sind beispielsweise Kamin-Türme. Zum Bau derartiger Türme sind obere, auch Kräne tragende Arbeitsbühnen und Plattformen erforderlich, die auf Türmen abgestützt werden müssen, die ebenfalls entsprechend dem Baufortschritt verlängert werden müssen. Würden für derartige Türme übliche Klettereinrichtungen verwendet werden, müßten die Türme, zumindest aber die Kletterverbände der einzelnen Turmstücke, nur deshalb wesentlich verstärkt werden, damit diese die Stützkräfte der Klettereinrichtung aufnehmen können. Es wäre also erforderlich, die einzelnen Turmstücke nur deshalb überzudimensionieren, um mit einer Klettereinrichtung den Turm verlängernde Turmstücke einbauen zu können.Chimney towers are particularly heavy, large and tall towers. The construction of such towers requires upper work platforms and platforms that also carry cranes, which have to be supported on towers, which also have to be extended in accordance with the construction progress. If customary climbing devices were used for such towers, the towers, or at least the climbing associations of the individual tower sections, would only have to be significantly strengthened so that they can absorb the supporting forces of the climbing device. It would therefore be necessary to oversize the individual tower sections only in order to be able to install tower sections that extend the tower with a climbing device.

Aufgabe der Erfindung ist es, eine Klettereinrichtung zu schaffen, die ohne Überdimensionierung des Turms auch dann ein Klettern gestattet, wenn der Turm auf größere Stützkräfte ausgelegt ist.The object of the invention is to provide a climbing device which allows climbing without oversizing the tower even if the tower is designed for greater supporting forces.

Erfindungsgemäß wird diese Aufgabe bei einer Klettereinrichtung nach dem Oberbegriff des Patentanspruchs 1 durch die kennzeichenden Merkmale des Patentanspruchs 1 gelöst.According to the invention, this object is achieved in a climbing device according to the preamble of patent claim 1 by the characterizing features of patent claim 1.

Die Erfindung geht zunächst von der Erkenntnis aus, daß allein eine Verdoppelung der hydraulischen Pressen und der Stützen mit Stützschuhen nicht zu größeren Hubkräften des Kletterrahmens führt, weil die Hubkräfte jeweils über zwei Stützschuhe bzw. Pressenschuhe in die Querstäbe der Kletterverbände der Turmstücke eingeleitet werden müssen und weil zwei Abstützstellen jeweils zu statisch unbestimmten Systemen in der Weise führen, daß eine gleichmäßige Abstützung erst dann gewährleistet ist, wenn es aufgrund von Verformungen der Querstäbe zu einem Kräfteausgleich gekommen ist. Während sich der Kräfteausgleich bei den Pressenschuhen hydraulisch durch eine Verbindung der Pressenzylinder erreichen läßt, ist dies bei den an in unterschiedlicher Höhe befindlichen Querstäben von Kletterverbänden angreifenden Stützschuhen der Stützen nicht möglich. Die Erfindung besteht somit nicht lediglich in einer Verdoppelung der hydraulischen Pressen und der Stützen mit Stützschuhen, sondern insbesondere darin, daß für die Stützschuhe eine Ausgleichsvorrichtung vorgesehen ist, die die Stützkräfte gleichmäßig auf beide Stützschuhe verteilt. Durch diese gleichmäßige Verteilung der Stützkräfte ist es möglich, ohne Überdimensionierung der Turmstücke eine Klettereinrichtung mit einem Kletterrahmen einzusetzen, der mit jeweils zwei hydraulischen Fressen und Stützen mit endseitigen Stützschuhen versehen ist, die jeweils an unterschiedlichen Querstäben der Kletterverbände des oder der Turmstücke angreifen.The invention is based initially on the knowledge that simply doubling the hydraulic presses and the supports with support shoes does not lead to greater lifting forces of the climbing frame leads because the lifting forces must be introduced into the crossbars of the climbing structures of the tower sections via two support shoes or press shoes and because two support points each lead to statically indeterminate systems in such a way that even support is only guaranteed if it is caused by deformation the cross bars have come to a balance of forces. While the balancing of forces in the press shoes can be achieved hydraulically by connecting the press cylinders, this is not possible in the case of the support shoes of the supports, which act on cross bars of climbing associations located at different heights. The invention thus consists not only in doubling the hydraulic presses and supports with support shoes, but in particular in that a compensation device is provided for the support shoes, which distributes the support forces evenly over both support shoes. This uniform distribution of the support forces makes it possible to use a climbing device with a climbing frame without overdimensioning the tower sections, which is provided with two hydraulic feeds and supports with end support shoes, which each engage different cross bars of the climbing associations of the tower section or sections.

Eine bevorzugte Ausführungsform der Erfindung ist Gegenstand des Anspruchs 2. Durch die Ausgleichsvorrichtung nach dem Anspruch 2 wird eine gleichmäßige Verteilung der Stützkräfte auf die beiden Schuhe auf das wippenartige Ausgleichsstück erreicht, das sich stets in der Weise ausrichtet, daß die Stützkräfte gleichmäßig auf beide belasteten Querstäbe des Kletterverbandes eingeleitet werden. Zweckmäßigerweise liegt die gelenkige Verbindung des Ausgleichsstücks mit der oberen Stütze etwa mittig oberhalb zwischen dem Stützschuhteil und der gelenkigen Verbindung mit der unteren Stütze.A preferred embodiment of the invention is the subject of claim 2. By the compensation device according to claim 2, a uniform distribution of the support forces on the two shoes is achieved on the rocker-like compensator, which is always aligned in such a way that the support forces evenly on both loaded cross bars of the climbing association. The articulated connection of the compensating piece with the upper support is expediently located approximately centrally between the support shoe part and the articulated connection with the lower support.

Das von dem Kletterrahmen 10 der Klettereinrichtung eingefaßte Turmstück 1 weist einen etwa quadratischen Querschnitt auf und besteht aus den parallel zueinander verlaufenden Eckstielen 2,3,4,5, die durch Stäbe miteinander verbunden sind. Die zwischen den Eckstielen 2,4 befindlichen Stäbe bilden den Kletterverband, der aus parallel zueinander verlaufenden und mit den Eckstielen 2,4 verbundenen Querstäben 6 und Diagonalstäben 7,8 besteht, deren obere Enden jeweils mit den Querstäben 6 in deren mittleren Knotenpunkt 9 verbunden sind und deren unteren Enden im Bereich der Eckstiele 2,4 mit diesen und den darunter liegenden Querstäben 6 verbunden sind. Auf diese Weise wird ein Kletterverband geschaffen, von dem Querstäb 6 in ihrem mittleren Bereich die von den Stützschuhen und Pressenschuhen übertragenen vertikalen Stützkräfte aufzunehmen vermögen.The tower section 1 enclosed by the climbing frame 10 of the climbing device has an approximately square cross section and consists of the corner posts 2, 3, 4, 5 which run parallel to one another and are connected to one another by rods. The rods located between the corner posts 2.4 form the climbing association, which consists of parallel bars 6 and diagonal bars 7, 8 which are connected to the corner posts 2.4 and whose upper ends are each connected to the cross bars 6 at their central node 9 and whose lower ends in the area of the corner posts 2, 4 are connected to the latter and the transverse bars 6 below. In this way, a climbing bandage is created, from which cross bars 6 are able to absorb the vertical support forces transmitted from the support shoes and press shoes in their central region.

Die übrigen drei Seiten des Turmstücks werden durch Diagonalstäbe 11,12 gebildet, die zick-zack-förmig zwischen den Eckstielen verlaufen und in gemeinsamen Knotenpunkten miteinander und mit den Eckstielen verbunden sind.The remaining three sides of the tower section are formed by diagonal bars 11, 12 which run in a zigzag shape between the corner posts and are connected to one another and to the corner posts at common nodes.

Im unteren und oberen Endbereich sind die Eckstiele durch Querstäbe miteinander verbunden, die in einer gemeinsamen Ebene liegen.In the lower and upper end area, the corner posts are connected to one another by cross bars that lie in a common plane.

Der das Turmstück 1 einfassende Kletterrahmen besteht ebenfalls aus vier Eckstielen 14,15,16,17, die durch quer- und diagonalverlaufende Stäbe miteinander verbunden sind. Auf seiner dem Kletterverband 6,7, des Turmstücks 1 gegenüberliegende Seite weist der Kletterrahmen 10 einen offenen Bereich 18 auf, der dem Einschieben von Turmstücken bzw. dem Ausfahren von Turmstücken dient. Unterhalb dieses offenen Bereiches kann der Kletterrahmen 10 durch lösbare Stäbe miteinander verbunden sein, die sich entfernen lassen, damit ggf. nach der Montage die Klettereinrichtung mit Kletterrahmen nach Entfernen der Stäbe seitwärts ausgehoben werden kann.The climbing frame enclosing the tower section 1 also consists of four corner posts 14, 15, 16, 17, which are transverse and diagonal Rods are interconnected. On its side opposite the climbing bandage 6, 7, of the tower section 1, the climbing frame 10 has an open area 18, which is used for inserting tower sections or extending tower sections. Below this open area, the climbing frame 10 can be connected to one another by detachable rods that can be removed so that, if necessary, the climbing device with the climbing frame can be lifted sideways after removal of the rods after assembly.

Auf der Seite des Kletterverbandes des Turmstücks 1 ist der Kletterrahmen mit zwei Querstäben 21,22 versehen, die in mittleren Knotenpunkten jeweils mit den unteren Enden zweier Diagonalstäbe 22,23 verbunden sind, deren oberen Enden im Bereich darüberliegender Querstäbe mit diesen und den Eckstielen 14,17 verbunden sind. Die auf diese Weise mittig abgestützten Querstäbe 21,22 weisen an ihren Unterseiten Gelenkstücke auf, an die die Zylinder 26,27 von hydraulischen Pressen angelenkt sind, deren Kolbenstangen 28,29 Pressenschuhe 30,31 tragen, mit deren äußeren Enden Klettertraversen 32,33 mittig verbunden sind, die an ihren Enden mit nach unten ragenden Schenkeln 34 versehen sind.On the side of the climbing association of the tower section 1, the climbing frame is provided with two cross bars 21, 22, which are connected at middle nodes to the lower ends of two diagonal bars 22, 23, the upper ends of which in the area of the cross bars above them and the corner posts 14, 17 are connected. The transverse rods 21, 22, which are supported in the middle in this way, have on their undersides articulated pieces to which the cylinders 26, 27 are articulated by hydraulic presses, the piston rods 28, 29 of which carry press shoes 30, 31 and the outer ends of the climbing beams 32, 33 in the center are connected, which are provided at their ends with downwardly projecting legs 34.

Beidseits des Zylinders 26 der oberen Presse sind im mittleren Bereich des Querstabes 20 profilierte Stützstäbe 38,39 angelenkt, an deren unteren Enden wippenartige Ausgleichsstücke 40,41 angelenkt sind. Diese wippenartigen Ausgleichsstücke 40,43
weisen etwa die Grundform eines gleichschenkeligen Dreiecks auf, wobei die Stützstäbe 38,39 im Bereich der Spitzen der etwa dreiecksförmigen Ausgleichsstücke angelenkt sind. Der innere Teil der Basisfläche 42 des Ausgleichsstücks bildet einen Stützschuh, der sich auf einem Querstab des Kletterverbandes des Turmstücks 1 abstützt. An den äußeren Bereichen der beiden dreiecksförmigen Ausgleichsstücke sind um die Gelenkbolzen 44,45 Stützen 46,47 gelagert, deren unteren Enden Stützschuhe bilden, die sich auf einem unteren Querstab 48 des Kletterverbandes des Turmstücks abstützen. Die Stützen 38,39 und 46,47 sind oberhalb der Ausgleichsstücke 40,41 bzw. oberhalb der Stützschuhe mit Stütztraversen 50,51 versehen, die am besten aus Fig. 1 ersichtlich sind und die sich auf den Eckstielen 14,17 des Kletterrahmens abstützen.Profiled support rods 38, 39 are articulated on both sides of the cylinder 26 of the upper press in the central region of the cross bar 20, and rocker-like compensating pieces 40, 41 are articulated at their lower ends. These rocker-like compensating pieces 40, 43
have approximately the basic shape of an isosceles triangle, the support rods 38, 39 being articulated in the region of the tips of the approximately triangular compensation pieces. The inner part of the base surface 42 of the compensating piece forms a support shoe which is supported on a crossbar of the climbing association of the tower piece 1. On the outer areas of the two triangular compensating pieces, supports 46, 47 are mounted around the hinge pins 44, 45, the lower ends of which form support shoes which are supported on a lower cross bar 48 of the climbing association of the tower piece. The supports 38, 39 and 46, 47 are provided above the compensating pieces 40, 41 and above the support shoes with support cross members 50, 51, which are best shown in FIG. 1 can be seen and which are supported on the corner posts 14, 17 of the climbing frame.

Der Abstand der Ausgleichsstücke 40,41 von den unteren Stützschuhe bildenden Enden der Stützen 46,47 ist so gewählt, daß sich die Stützschuhteile der Ausgleichsstücke 40,41 und die Stützschuhe der Stützen 46,47 auf aufeinanderfolgenden Querstäben des Kletterverbandes abstützen.The distance of the compensating pieces 40, 41 from the ends of the supports 46, 47 forming the lower support shoes is selected such that the support shoe parts of the compensating pieces 40, 41 and the support shoes of the supports 46, 47 are supported on successive cross bars of the climbing association.

Die dreiecksförmigen Ausgleichsstücke 40,41 bilden wippenartige Teile, die um die obere gelenkige Verbindung mit den Stützen 38,39 in der Weise schwenken können, daß der innere Stützschuhteil der Basis und die unteren Stützstäbe 46,47 mit den Stützschuhen etwa gleiche Stützkräfte aufnehmen.The triangular compensating pieces 40, 41 form rocker-like parts which can pivot about the upper articulated connection with the supports 38, 39 in such a way that the inner support shoe part of the base and the lower support rods 46, 47 with the support shoes absorb approximately the same supporting forces.

Die Klettertraversen 32,33 sind an den Pressenschuhen 30,31 derart befestigt, daß die Fressen pendelartig mit Schräglage nach innen hin hängen. Entsprechend sind auch die Stütztraversen 50,51 an den Stützen 38,39 und 46,47 derart befestigt, daß auch diese in einer nach innen hin gerichteten Schräglage hängen. Auf diese Weise finden die Pressenschuhe und die Stützschuhe jeweils ihre Stützstellung auf den Querstäben des Kletterverbandes, ohne daß diese eingehoben werden müßten. Durch die Abstützung der Klettertraversen und der Stütztraversen auf den Eckstielen des
Turmstücks und des Kletterrahmens ist gewährleistet, daß die Querstäbe des Kletterverbandes des Sturmstücks nur mit vertikalen Stützkräften und nicht auch mit in horizontaler Richtung wirkenden Biegekräften beaufschlagt werden.The climbing traverses 32, 33 are attached to the press shoes 30, 31 in such a way that the faces hang in a pendulum-like manner with an inclined position toward the inside. Correspondingly, the support cross members 50, 51 are fastened to the supports 38, 39 and 46, 47 in such a way that they too hang in an inclined position directed inward. In this way, the press shoes and the support shoes each find their support position on the cross bars of the climbing association, without these having to be lifted. By supporting the climbing crossbars and the supporting crossbars on the corner posts of the
The tower section and the climbing frame ensure that the cross bars of the climbing section of the storm section are only subjected to vertical supporting forces and not to bending forces acting in the horizontal direction.
