Description

HebebühneLifting platform

Die Erfindung betrifft eine Hebebühne zum Anheben von Fahrzeugen.The invention relates to a lifting platform for lifting vehicles.

Aus der DE 36 05 650 C2 ist eine mobile hydraulische Hebebühne zum Anheben von Fahrzeugen in Überkopfhöhe bekannt. Diese mobile Hebebühne umfasst eine Bodengruppe, welche beim Anheben von Fahrzeugen ortsfest aufliegt. Beim Nichtgebrauch kann diese Hebebühne mittels eines Fahrwerkes in eine weitere Gebrauchs- oder Verstauposition verfahren werden. Die Bodengruppe der Hebebühne umfasst zwei Bodengruppenhälften sowie ein Mittelteil, wobei die beiden Bodengruppenhälften über das Mittelteil fest miteinander verbunden und zueinander angeordnet sind. Jede Bodengruppenhälfte weist einen Antrieb auf, durch welchen eine Parallelogrammführungsvorrichtung der Bodengruppenhälfte auf und ab bewegbar ist. Diese Parallelogrammführungsvorrichtung umfasst einen Lastarm und einen Führungsarm, sodass beim Heben und Senken der Parallelogrammführungsvorrichtung ein am freien Endbereich angeordneter Träger horizontal ausgerichtet bleibt. Der an der Parallelogrammführungsvorrichtung vorgesehene Träger nimmt zwei schwenkbar am Träger angeordnete Tragarme auf. Diese Tragarme können aus einer Nichtgebrauchsposition, bei der die Tragarme entgegengesetzt ausgerichtet und parallel zur Parallelogrammführungsvorrichtung positioniert sind, in eine Gebrauchsposition geschwenkt werden, um ein zwischen den Bodengruppenhälften und in die Hebebühne eingefahrenes Fahrzeug anzuheben.From the DE 36 05 650 C2 a mobile hydraulic lifting platform for lifting vehicles at overhead height is known. This mobile lifting platform includes a floor assembly which rests in a stationary position when vehicles are lifted. When not in use, this lift can be moved to another use or stowage position by means of a chassis. The floor assembly of the lifting platform comprises two floor assembly halves and a middle part, the two floor assembly halves being firmly connected to one another via the middle part and arranged to one another. Each floor assembly half has a drive, by means of which a parallelogram guide device of the floor assembly half can be moved up and down. This parallelogram guide device comprises a load arm and a guide arm, so that when the parallelogram guide device is raised and lowered, a carrier arranged at the free end region remains horizontally aligned. The carrier provided on the parallelogram guide device accommodates two support arms which are pivotably arranged on the carrier. These support arms can be pivoted from a non-use position, in which the support arms are oriented in opposite directions and positioned parallel to the parallelogram guide device, into a use position, in order to lift a vehicle that has been retracted between the floor assembly halves and into the lifting platform.

Jede Bodengruppenhälfte ist an dem Mittelteil, welches in Form eines Schutzrohres ausgebildet ist, befestigt. Das Mittelteil weist am jeweiligen Ende einen Flanschabschnitt auf, der mit einer Seitenfläche des Gehäuses der Bodengruppenhälfte verschraubt ist.Each floor pan half is attached to the middle part, which is designed in the form of a protective tube. At the respective end, the middle part has a flange section which is screwed to a side surface of the housing of the floor assembly half.

Aufgrund von Maßtoleranzen kann nach dem Zusammenbau eine voneinander abweichende Ausrichtung der Tragarme in einer Arbeitsposition innerhalb eines Arbeitsraumes, in der das Fahrzeug angehoben ist, gegeben sein. Eine Nachjustierung oder Einstellung über die Anschlussstelle zwischen der Bodengruppenhälfte und dem Mittelteil ist schwierig und nur bedingt möglich.Due to dimensional tolerances, after assembly, a different alignment of the support arms in a working position within a working space in which the vehicle is raised, be given. A readjustment or setting via the connection point between the floor assembly half and the middle part is difficult and only possible to a limited extent.

Der Erfindung liegt die Aufgabe zugrunde, eine Hebebühne vorzuschlagen, bei der die Tragarme in einfacher Weise zueinander ausrichtbar sind.The invention is based on the object of proposing a lifting platform in which the support arms can be aligned with one another in a simple manner.

Diese Aufgabe wird durch eine Hebebühne gelöst, bei welcher ein Neigungswinkel zwischen dem Tragarm und der Hebevorrichtungeinstellbar ist. Dadurch können die einander gegenüberliegenden Tragarme beispielsweise in einer gemeinsamen Horizontalen schwenkbar zueinander ausgerichtet werden. Auch können die einander gegenüberliegenden Tragarme so ausgerichtet werden, dass diese mit ihren freien Enden geringfügig oberhalb der Horizontalen liegen, sodass bei einer Lastaufnahme die Tragarme beispielsweise nahe zur Horizontalen oder in der Horizontalen liegen. Durch die Veränderung des Neigungswinkels zwischen dem Tragarm und der Hebevorrichtung kann eine individuelle Anpassung des zumindest einen Tragarmes von jeder Bodengruppenhälfte erfolgen, sodass der oder die an einer rechten Hebevorrichtung angeordneten Tragarme unabhängig von dem oder den an einer linken Hebevorrichtung vorgesehenen Tragarmen einstellbar ist oder sind.This object is achieved by a lifting platform in which an angle of inclination between the support arm and the lifting device can be adjusted. As a result, the mutually opposite support arms can, for example, be aligned pivotably with respect to one another in a common horizontal. The support arms lying opposite one another can also be aligned in such a way that their free ends are slightly above the horizontal, so that when a load is picked up, the support arms are, for example, close to the horizontal or in the horizontal. By changing the angle of inclination between the support arm and the lifting device, the at least one support arm of each floor assembly half can be individually adjusted so that the support arm (s) arranged on a right lifting device is or are adjustable independently of the support arm or arms provided on a left lifting device.

Bevorzugt ist vorgesehen, dass zur Einstellung des Neigungswinkels zwischen dem Tragarm und der Hebevorrichtung eine Einstellvorrichtung zwischen dem Träger und der Hebevorrichtung oder zwischen dem Tragarm und dem Träger vorgesehen ist. Dadurch kann insbesondere bei der Positionierung des Trägers mit dem zumindest einen Tragarm in einer Arbeitsposition eine individuelle Ausrichtung des zumindest einen Tragarms ermöglicht sein. Durch die Ausrichtung der Tragarme, insbesondere in einer gemeinsamen Horizontalen, kann die Arbeitssicherheit erhöht sein.It is preferably provided that an adjusting device is provided between the support and the lifting device or between the support arm and the support in order to adjust the angle of inclination between the support arm and the lifting device. As a result, in particular when the carrier is positioned with the at least one support arm in a working position, an individual alignment of the at least one support arm can be made possible. By aligning the support arms, in particular in a common horizontal line, work safety can be increased.

Gemäß einer bevorzugten Ausführungsform der Hebebühne ist vorgesehen, dass durch die Einstelleinrichtung der Träger zur Ausrichtung der Tragarme in der Neigung zur Schwenkachse des Schwenkbolzens und/oder zur Lagerachse des Lagerbolzens oder zu beiden einstellbar ist. Die Schwenkachse und die Lagerachse an der einen Hebevorrichtung sind parallel zueinander ausgerichtet. Diese Schwenk- und Lagerachse der einen Hebevorrichtung fluchten vorzugsweise mit der Schwenk- und Lagerachse der gegenüberliegenden Parallellogrammführungsvorrichtung. Die Neigungseinstellung des Trägers erfolgt dahingehend, dass der Träger um seine Längsachse drehbar oder kippbar ist. Die Längsachse des Trägers erstreckt sich rechtwinklig zur Schwenkachse des Schwenkbolzens und Lagerachse des Lagerbolzens. Durch die Neigung des Trägers kann ein freies Ende des Tragarmes, welches in den Arbeitsraum eingeschwenkt ist, in der Höhe zum Boden veränderbar sein, wodurch eine Ausrichtung der einander zugeordneten Tragarme, insbesondere in einer gemeinsamen Horizontalen, ermöglicht wird.According to a preferred embodiment of the lifting platform, it is provided that, by means of the adjustment device, the support for aligning the support arms in the inclination to the pivot axis of the pivot pin and / or is adjustable to the bearing axis of the bearing pin or to both. The pivot axis and the bearing axis on the one lifting device are aligned parallel to one another. This pivot and bearing axis of the one lifting device are preferably aligned with the pivoting and bearing axis of the opposite parallelogram guide device. The inclination of the carrier is adjusted to the effect that the carrier can be rotated or tilted about its longitudinal axis. The longitudinal axis of the carrier extends at right angles to the pivot axis of the pivot pin and the bearing axis of the bearing pin. As a result of the inclination of the support, a free end of the support arm, which is pivoted into the work space, can be changed in height relative to the floor, which enables the support arms assigned to one another to be aligned, in particular in a common horizontal line.

Die Einstellvorrichtung umfasst bevorzugt eine Ausgleichsplatte mit einer Bohrung, welche an einem Ende des Schwenkbolzens oder des Lagerbolzens aufsetzbar und an oder in dem Träger befestigbar ist. Durch diese Ausgleichsplatte kann der Träger in einer Nullpunktlage, also rechtwinklig zur Parallelgrammführungsvorrichtung, oder in einer zur Schwenkachse oder zur Lagerachse verdrehten oder gekippten Position anordenbar sein. Bei dieser gedrehten oder gekippten Position genügen bereits wenige Winkelgrade, um eine Ausrichtung der Tragarme zu bewirken.The adjustment device preferably comprises a compensating plate with a bore which can be placed on one end of the pivot pin or the bearing pin and fastened to or in the carrier. By means of this compensating plate, the carrier can be arranged in a zero point position, that is to say at right angles to the parallelogram guide device, or in a position that is rotated or tilted to the pivot axis or to the bearing axis. In this rotated or tilted position, just a few degrees of angle are sufficient to align the support arms.

Der Träger der verfahrbaren Hebebühne weist vorteilhafterweise zumindest zwei parallel zueinander beabstandeten Seitenwänden auf, die jeweils eine Durchbrechung für den Schwenkbolzen und den Lagerbolzen aufweisen. In einer der beiden Seitenwände ist anstelle der Durchbrechung eine Zentrieraufnahme vorgesehen, in welcher die Ausgleichsplatte, die den Schwenkbolzen oder Lagerbolzen aufnimmt, einsetzbar ist und sich in der Seitenwand abstützt. Dadurch bleibt der Träger bezüglich der Positionierung des Schwenkbolzen oder Lagerbolzen in der einen Seitenwand des Trägers auf gleicher Höhe zur Schwenk- oder Lagerachse und die gegenüberliegende Seitenwand des Trägers kann gegenüber der Schwenk- oder Lagerachse einen größeren oder geringeren Abstand einnehmen. Diese Dreh- oder Kippbewegung des Trägers bewirkt die Einstellung des freien Endes des Trägers in der Höhe zum Boden bzw. zum gegenüberliegenden Träger. Bevorzugt ist die Einnahme des größeren oder geringeren Abstandes zur Schwenk- oder Lagerachse an einer Außenseite des Trägers vorgesehen, also diejenige Seite, die entfernt zu einer Längsmittelachse der Hebebühne liegt.The carrier of the movable lifting platform advantageously has at least two parallel spaced apart side walls which each have an opening for the pivot pin and the bearing pin. In one of the two side walls, instead of the opening, a centering receptacle is provided, in which the compensating plate, which receives the pivot pin or bearing pin, can be inserted and is supported in the side wall. As a result, the carrier remains with regard to the positioning of the pivot pin or bearing pin in one side wall of the carrier at the same height as the pivot or bearing axis and the opposite side wall of the carrier can be larger or larger than the pivot or bearing axis take a closer distance. This rotating or tilting movement of the carrier causes the free end of the carrier to be adjusted in height relative to the floor or to the opposite carrier. The greater or lesser distance to the pivot or bearing axis is preferably provided on an outside of the carrier, that is to say that side which is remote from a longitudinal center axis of the lifting platform.

Des Weiteren ist bevorzugt vorgesehen, dass die Zentrieraufnahme in der Seitenwand V-förmig oder wannenförmig ausgebildet ist, sich in Lastrichtung verengt und die Ausgleichsplatte eine komplementäre Außenkontur aufweist, sodass diese formschlüssig in der Zentrieraufnahme anliegt. Dadurch ist bei einer Belastung der Hebebühne sichergestellt, dass die aufzunehmende Kraft, welche über die Tragarme in den Träger eingeleitet werden und vom Träger über die Bolzen in die Parallellogrammführung abgeleitet werden, von der Ausgleichsplatte über die Zentrieraufnahme sicher in die Seitenwand eingeleitet werden kann.Furthermore, it is preferably provided that the centering receptacle in the side wall is V-shaped or trough-shaped, narrows in the load direction and the compensating plate has a complementary outer contour so that it rests positively in the centering receptacle. In this way, when the lift is loaded, it is ensured that the force to be absorbed, which is introduced into the carrier via the support arms and derived from the carrier via the bolts in the parallelogram guide, can be safely introduced into the side wall from the compensation plate via the centering mount.

Eine weitere bevorzugte Ausgestaltung der Hebebühne sieht vor, dass zur Fixierung der Ausgleichsplatte in der Zentrieraufnahme eine Halteeinrichtung vorgesehen ist, die lösbar an der Seitenwand, insbesondere an einer Außenseite der Seitenwand, vorgesehen ist. Dadurch ist eine gute Zugänglichkeit und eine einfache Montage und Demontage der Halteeinrichtung sowie ein einfaches Auswechseln einer Ausgleichplatte ermöglicht, um verschiedene Neigungswinkel einzustellen.Another preferred embodiment of the lifting platform provides that a holding device is provided to fix the compensating plate in the centering receptacle, which is detachably provided on the side wall, in particular on an outside of the side wall. This enables good accessibility and simple assembly and disassembly of the holding device as well as simple replacement of a compensating plate in order to set different angles of inclination.

Vorzugsweise ist die Halteeinrichtung als eine Halteplatte ausgebildet, welche zumindest ein lösbares Befestigungselement umfasst, durch welches die Halteplatte mit der Seitenwand befestigbar ist. Vorzugsweise ist zumindest ein Halteelement vorgesehen, durch welches die Ausgleichsplatte zur Halteplatte lösbar fixiert ist. Des Weiteren ist bevorzugt ein Fixierelement vorgesehen, durch welches die Halteplatte lösbar zum Schwenkbolzen oder Lagerbolzen fixierbar ist. Bevorzugt greifen an der Halteplatte das zumindest eine Befestigungselement, Halteelement und Fixierelement an. Dadurch sind alle Bauteile zueinander gesichert.The holding device is preferably designed as a holding plate which comprises at least one detachable fastening element, by means of which the holding plate can be fastened to the side wall. At least one holding element is preferably provided, by means of which the compensating plate is releasably fixed to the holding plate. Furthermore, a fixing element is preferably provided, by means of which the holding plate can be releasably fixed to the pivot pin or bearing pin. The at least one fastening element, holding element and fixing element preferably engage on the holding plate. This means that all components are secured to one another.

Des Weiteren ist bevorzugt vorgesehen, dass die Halteplatte die Zentrieraufnahme in der Seitenwand in der montierten Position vollständig überdeckt. Dadurch kann eine quasi geschlossene Seitenwand des Trägers geschaffen werden, wodurch eine Verletzungsgefahr verringert wird.Furthermore, it is preferably provided that the holding plate the Centering mount in the side wall completely covered in the assembled position. As a result, a quasi-closed side wall of the carrier can be created, which reduces the risk of injury.

Vorteilhafterweise sind mehrere Ausgleichsplatten für eine Einstellvorrichtung vorgesehen, die im Abstand zwischen einer an der Ausgleichsplatte vorgesehenen Bezugsfläche und einer Längsmittelachse der Bohrung voneinander abweichen. Dadurch kann eine Veränderung im Neigungswinkel des Trägers zur Schwenkachse oder Lagerachse eingestellt werden. Vorzugsweise sind an den Ausgleichsplatten Markierungen oder Angaben vorgesehen, um dem Benutzer den jeweiligen Abstand zu signalisieren, der durch diese Ausgleichsplatte einstellbar ist.A plurality of compensating plates are advantageously provided for an adjusting device, which differ from one another in the distance between a reference surface provided on the compensating plate and a longitudinal center axis of the bore. This allows a change in the angle of inclination of the carrier to the pivot axis or bearing axis to be set. Markings or information are preferably provided on the compensating plates in order to signal to the user the respective distance that can be adjusted by this compensating plate.

Eine weitere bevorzugte Ausführungsform der Hebebühne sieht vor, dass der Schwenkbolzen und der Lagerbolzen durch eine Radiallagerung um eine ortsfeste Schwenk- und Lagerachse zum Lastarm und Führungsarm drehbar aufgenommen sind. Dadurch wird ermöglicht, dass nur durch die Einstellvorrichtung der Träger um seine Längsachse gedreht wird, das heißt, dass dieser in und entgegen dem Uhrzeigersinn zur Längsmittelachse der Hebebühne in seiner Lage verändert werden kann.Another preferred embodiment of the lifting platform provides that the pivot pin and the bearing pin are rotatably received by a radial bearing around a fixed pivot and bearing axis to the load arm and guide arm. This enables the carrier to be rotated around its longitudinal axis only by means of the adjustment device, that is to say that its position can be changed in and counterclockwise to the longitudinal center axis of the lifting platform.

Eine bevorzugte Ausführungsform der Hebebühne sieht vor, dass eine beim Anheben von Fahrzeugen ortsfeste Bodengruppe vorgesehen ist, welche zwei Bodengruppenhälften umfasst, die über zumindest eine, vorzugsweise lösbare, Anschlussstelle mit einem Mittelteil fest zueinander angeordnet sind.A preferred embodiment of the lifting platform provides that a stationary floor assembly is provided when vehicles are lifted, which floor assembly comprises two floor assembly halves which are fixed to one another via at least one, preferably detachable, connection point with a central part.

Des Weiteren ist bei einer vorteilhaften Ausgestaltung der Hebebühne vorgesehen, dass an jeder Bodengruppenhälfte eine Hebevorrichtung, insbesondere eine Parallelogrammführungsvorrichtung oder eine Scherenführungsvorrichtung angeordnet ist, welche vorzugsweise einen Lastarm und einen Führungsarm umfasst, die mit zumindest einem an oder in der zumindest einen Bodengruppenhälfte angeordneten Antrieb aus einer am Boden angeordneten Ausgangsposition in eine Arbeitsposition überführbar sind und welche in jeweils einem Endbereich der Hebevorrichtung, insbesondere der Parallelogrammführungsvorrichtung oder der Scherenführungsvorrichtung, einen Träger aufnimmt, der über einen Schwenkbolzen schwenkbar zum Lastarm gelagert ist und über einen Lagerbolzen schwenkbar zum Führungsarm gelagert ist, und jeder Träger zumindest einen schwenkbar daran angeordneten Tragarm aufnimmt, so dass die einander gegenüberliegenden Tragarme in einen zumindest zwischen den Hebevorrichtungen, insbesondere Parallelogrammführungsvorrichtungen oder zwischen den Scherenführungsvorrichtungen gebildeten Arbeitsraum schwenkbar sind.Furthermore, it is provided in an advantageous embodiment of the lifting platform that a lifting device, in particular a parallelogram guide device or a scissor guide device, is arranged on each floor assembly half, which preferably comprises a load arm and a guide arm with at least one drive arranged on or in the at least one floor assembly half a starting position arranged on the floor can be transferred into a working position and which in each case in an end area the lifting device, in particular the parallelogram guiding device or the scissor guiding device, receives a carrier which is pivotably mounted to the load arm via a pivot pin and is pivotably mounted to the guide arm via a bearing pin, and each carrier receives at least one pivotable support arm so that the opposing support arms can be pivoted into a working space formed at least between the lifting devices, in particular parallelogram guiding devices or between the scissor guiding devices.

Die Hebebühne ist insbesondere als verfahrbare Hebebühne ausgebildet, so dass diese an dem jeweiligen Gebrauchsort positionierbar ist.The lifting platform is designed in particular as a movable lifting platform so that it can be positioned at the respective place of use.

Diese Hebebühne 11 umfasst eine Bodengruppe 12, welche zwei Bodengruppenhälften 14 und ein dazwischen angeordnetes Mittelteil 15 umfasst. Durch das Mittelteil 15 sind die Bodengruppenhälften 14 vorzugsweise parallel zueinander beabstandet und ausgerichtet. Durch die Bodengruppenhälften 14 und das Mittelteil 15 wird eine U-förmige Bodengruppe 12 gebildet. Der offene Bereich stellt einen Einfahrbereich in einem Arbeitsraun 50 für ein Fahrzeug dar, welches so lange einfährt, bis dieses nahe dem Mittelteil 12 positioniert ist. Die Einfahrrichtung ist gemäß Pfeil 17 in der perspektivischen Ansicht der Hebebühne 11 in Figur 1 dargestellt. Die Einfahrrichtung liegt im Bereich einer Längsmittelachse 18 der Hebebühne 11. Die Längsmittelachse 18 erstreckt sich parallel zwischen den beiden Bodengruppenhälften 14 und ist mittig dazu angeordnet. Der Arbeitsraum 50 erstreckt sich zumindest zwischen den beiden Bodengruppenhälften 14.the Figure 1 shows a perspective view of a lifting platform 11 according to the invention. This lifting platform 11 comprises a floor assembly 12, which comprises two floor pan halves 14 and a middle part 15 arranged between them. By means of the middle part 15, the floor assembly halves 14 are preferably spaced apart and aligned parallel to one another. A U-shaped floor assembly 12 is formed by the floor assembly halves 14 and the central part 15. The open area represents a drive-in area in a work space 50 for a vehicle, which drives in until it is positioned near the central part 12. The direction of entry is indicated by arrow 17 in the perspective view of the lifting platform 11 in FIG Figure 1 shown. The direction of entry lies in the region of a longitudinal center axis 18 of the lifting platform 11. The longitudinal center axis 18 extends parallel between the two floor assembly halves 14 and is arranged in the center thereof. The work space 50 extends at least between the two floor assembly halves 14.

Jede Bodengruppenhälfte 14 umfasst ein Gehäuse 21, innerhalb welcher ein schematisch dargestellter Antrieb 22 vorgesehen ist. Des Weiteren nimmt jede Bodengruppenhälfte 14 eine Hebevorrichtung 24 auf, die in diesem Ausführungsbeispiel als eine Parallelogrammführungsvorrichtung ausgebildet ist. Alternativ kann die Hebevorrichtung 24 als Scherenführungsvorrichtung, insbesondere Halbschere, Vollschere oder Doppelschere, ausgebildet sein. Der zumindest eine Antrieb 22 hebt und senkt die Hebevorrichtung 24. Diese Hebevorrichtung 24 umfasst einen Lastarm 25, der um eine erste Schwenkachse 26 schwenkbar ist. Des Weiteren umfasst die Hebevorrichtung 24 einen Führungsarm 27, der um eine zweite Schwenkachse 28 schwenkbar ist, die zur ersten Schwenkachse 26 beabstandet ist. Beide Schwenkachsen 26, 28 sind an dem Gehäuse gelagert.Each floor assembly half 14 comprises a housing 21 within which a schematically illustrated drive 22 is provided. Furthermore, each floor assembly half 14 receives a lifting device 24, which in this exemplary embodiment is designed as a parallelogram guide device. Alternatively, the lifting device 24 can be designed as a scissors guide device, in particular half scissors, full scissors or double scissors. The at least one drive 22 raises and lowers the lifting device 24. This lifting device 24 comprises a load arm 25 which can be pivoted about a first pivot axis 26. Furthermore, the lifting device 24 comprises a guide arm 27 which can be pivoted about a second pivot axis 28 which is spaced apart from the first pivot axis 26. Both pivot axes 26, 28 are mounted on the housing.

Die Hebevorrichtung 24 weist an einem zum Gehäuse 21 entfernten Endbereich einen Träger 31 auf, der durch die Hebevorrichtung 24 während dem Heben und Senken der Hebevorrichtung 24 horizontal ausgerichtet bleibt. In Figur 1 sind die Hebevorrichtungen 24 in einer Arbeitsposition 32 vorgesehen. Eine solche Arbeitsposition 32 kann einer Überkopfhöhe entsprechen. In einer Nichtgebrauchsposition sind die Hebevorrichtungen 24 nahe dem Boden ausgerichtet oder auf dem Boden aufliegend positioniert.The lifting device 24 has, at an end region remote from the housing 21, a carrier 31 which remains horizontally aligned by the lifting device 24 during the lifting and lowering of the lifting device 24. In Figure 1 the lifting devices 24 are provided in a working position 32. Such a working position 32 can correspond to an overhead height. In a non-use position, the hoists 24 are oriented near the ground or on the ground positioned on top.

Jeder Träger 31 nimmt zumindest einen Tragarm 34 auf. Vorzugsweise sind jeweils zwei Tragarme 34 an dem Träger 31 vorgesehen. Diese Tragarme 34 sind um jeweils eine Lagerachse 35, 36 schwenkbar gelagert. Die Tragarme 34 können gleich lang ausgebildet sein. Alternativ kann der zum Einfahrbereich weisende, hintere Tragarm länger ausgebildet sein als der zum Mittelteil 15 weisende, insbesondere vordere Tragarm 34. Die Tragarme 34 sind bevorzugt als Teleskoptragarme ausgebildet.Each carrier 31 receives at least one support arm 34. Two support arms 34 are preferably provided on the carrier 31 in each case. These support arms 34 are each mounted so as to be pivotable about a bearing axis 35, 36. The support arms 34 can have the same length. Alternatively, the rear support arm facing the entry area can be made longer than the support arm 34 facing the central part 15, in particular the front support arm. The support arms 34 are preferably configured as telescopic support arms.

Die Hebebühne 11 ist bevorzugt als eine verfahrbare Hebebühne 11 ausgebildet. Jede Bodenbaugruppenhälfte 14 weist bevorzugt an einem vom Mittelteil 15 entfernten Ende eine Laufrolle 38 auf, die Teil eines Fahrwerkes ist. Des Weiteren kann eine nicht näher dargestellte Deichsel in einem mittleren Bereich am Mittelteil 15 befestigbar sein, sodass nach Anheben des Mittelteils die Hebebühne 11 sich auf einem Laufrad der Deichsel und den beiden Laufrollen 38 abstützt. Dadurch ist die Hebebühne 11 mobil und kann am jeweiligen Gebrauchsort verfahrbar sein. Nach dem Abnehmen der Deichsel ist diese Hebebühne 11 ortsfest und liegt auf dem Boden auf.The lifting platform 11 is preferably designed as a movable lifting platform 11. Each floor assembly half 14 preferably has, at an end remote from the central part 15, a roller 38 which is part of a chassis. Furthermore, a drawbar (not shown in detail) can be fastened in a central area on the central part 15, so that after the central part has been raised, the lifting platform 11 is supported on a running wheel of the drawbar and the two rollers 38. As a result, the lifting platform 11 is mobile and can be moved at the respective place of use. After removing the drawbar, this lifting platform 11 is stationary and rests on the ground.

Alternativ zu der in Figur 1 dargestellten Hebebühne 11 kann diese auch als eine ortsfeste Hebebühne 11 ausgebildet sein. In diesem Fall können die Laufrollen 38 entfallen. Auch kann bei einer ortsfesten Hebebühne 11 vorgesehen sein, dass diese aus den beiden zueinander ausgerichteten Bodenbaugruppenhälften 14 besteht. Ein Mittelteil 15 kann vorgesehen sein oder auch entfallen.As an alternative to the in Figure 1 The lifting platform 11 shown here can also be designed as a stationary lifting platform 11. In this case, the rollers 38 can be omitted. In the case of a stationary lifting platform 11, it can also be provided that it consists of the two floor assembly halves 14 that are aligned with one another. A middle part 15 can be provided or can be omitted.

Zur Ansteuerung der Hebebühne 11 aus einer Nichtgebrauchsposition in eine Arbeitsposition 32 ist eine Steuerung 41 vorgesehen, welche beispielsweise an einer der beiden Bodengruppenhälften 14 angeordnet ist. Diese Steuerung 41 kann ein Steuersignal an den oder die jeweiligen Antriebe 22 ausgeben. Der Antrieb 22 kann ein Hydraulikzylinder sein, der elektrisch ansteuerbar ist. Bevorzugt ist in jedem Gehäuse 21 der Bodengruppenhälfte 14 ein Antrieb 22 vorgesehen. Die Steuerung 41 umfasst Überwachungssensoren zur Synchronisation der Anhebe- und Absenkbewegung der jeweiligen Hebevorrichtung 24. Von der Steuerung 41 können Steuerleitungen einerseits in die unmittelbar zugeordnete Bodengruppenhälfte 14 geführt werden. Andererseits können Steuerleitungen innerhalb des Mittelteils 15 zur gegenüberliegenden Bodengruppenhälfte 14 geführt werden.To control the lifting platform 11 from a non-use position to a working position 32, a control 41 is provided, which is arranged, for example, on one of the two floor assembly halves 14. This controller 41 can output a control signal to the respective drive or drives 22. The drive 22 can be a hydraulic cylinder which can be controlled electrically.

On the one hand, control lines can be routed from the controller 41 into the directly assigned floor assembly half 14. On the other hand, control lines can be routed within the middle part 15 to the opposite floor assembly half 14.

In Figur 2 ist eine schematische Ansicht von vorne auf die Hebebühne 11 gemäß Figur 1 in der Arbeitsposition 32 dargestellt. Durch die Kraft F1 ist die auf die Tragarme 34 wirkende Kraft symbolisiert, die bei einem in der Arbeitsposition 32 angehobenen Fahrzeug wirkt. Zur Erhöhung der Arbeitssicherheit ist es erforderlich, dass die zumindest zwei einander gegenüberliegenden Tragarme 34 nahezu oder in einer gemeinsamen Horizontalen ausgerichtet sind. Dadurch kann eine Schieflage des Fahrzeuges in der Arbeitsposition 32 verhindert werden.In Figure 2 FIG. 11 is a schematic view from the front of the lifting platform 11 according to FIG Figure 1 shown in the working position 32. The force F 1 symbolizes the force which acts on the support arms 34 and which acts when the vehicle is raised in the working position 32. To increase work safety, it is necessary that the at least two opposite support arms 34 are aligned almost or in a common horizontal. This prevents the vehicle from tilting in the working position 32.

Aufgrund von Maßtoleranzen der ersten und zweiten Bodengruppenhälfte 14 kann der Fall eintreten, dass der oder die Tragarme 34 der ersten Bodengruppenhälfte 14 und/oder der oder die Tragarme 34 der zweiten Bodengruppenhälfte 14 nicht zueinander ausgerichtet sind und/oder außerhalb der Horizontalen liegen. Dabei können die freien Enden der Tragarme oberhalb oder unterhalb der Horizontalen ausgerichtet sein.Due to dimensional tolerances of the first and second floor assembly halves 14, the case may arise that the support arm (s) 34 of the first floor assembly half 14 and / or the support arm (s) 34 of the second floor assembly half 14 are not aligned with one another and / or lie outside the horizontal. The free ends of the support arms can be aligned above or below the horizontal.

An jeder Bodengruppenhälfte 14 ist zumindest eine Einstelleinrichtung 51 vorgesehen, durch welche die Neigung des zumindest einen Tragarms 34 der Hebevorrichtung 24 einstellbar ist. Bevorzugt ist ein Winkel zwischen dem zumindest einen Tragarm 34 und der Hebevorrichtung 24 von 90° vorgesehen. Sofern jedoch die Hebevorrichtung 24 in einer angehobenen Position außerhalb einer Vertikalen ausgerichtet ist, bedarf es der Einstellung der Neigung des zumindest einen Tragarms 34, sodass dieser wiederum in der Horizontalen ausgerichtet ist.At least one adjusting device 51 is provided on each floor assembly half 14, by means of which the inclination of the at least one support arm 34 of the lifting device 24 can be adjusted. An angle between the at least one support arm 34 and the lifting device 24 of 90 ° is preferably provided. If, however, the lifting device 24 is aligned in a raised position outside of a vertical, it is necessary to adjust the inclination of the at least one support arm 34 so that it is in turn aligned in the horizontal.

Die Einstellvorrichtung 51 ist gemäß einer bevorzugten Ausführungsform zwischen dem Träger 31 und der Hebevorrichtung 24 vorgesehen. Die Einstellvorrichtung 51 ist bevorzugt an einer Außenseite des Trägers 31 vorgesehen. Dieser kann auch an einer Innenseite des Trägers 31 vorgesehen sein.According to a preferred embodiment, the adjusting device 51 is provided between the carrier 31 and the lifting device 24. The adjustment device 51 is preferably provided on an outside of the carrier 31. This can also be provided on an inside of the carrier 31.

In Figur 3 ist eine schematische Schnittansicht entlang der Linie III-III in Figur 1 dargestellt. Dieser schematische Teilschnitt erstreckt sich durch einen oberen Endbereich der Hebevorrichtung 24 sowie einen Teil des Trägers 31.In Figure 3 FIG. 3 is a schematic sectional view taken along line III-III in FIG Figure 1 shown. This schematic partial section extends through an upper end region of the lifting device 24 and part of the carrier 31.

Im oberen Endbereich des Lastarmes 25 ist eine Lagerbuchse 52 vorgesehen, welche eine Radiallagerung 53 aufnimmt, durch welche ein Schwenkbolzen 54 drehbar um eine Schwenkachse 55 zum Lastarm 25 gelagert ist. Der Träger 31 weist zumindest eine erste Seitenwand 56 und eine zweite Seitenwand 57 auf, die vorzugsweise parallel zueinander beabstandet sind. Die erste Seitenwand 56 bildet eine Außenseite des Trägers 31. Die zweite Seitenwand 57 bildet eine Innenseite des Trägers 31. An dieser zweiten Seitenwand 57 ist eine Tragarmhalterung 58 vorgesehen, welche den Tragarm 34 um eine Lagerachse 35, 36 schwenkbar aufnimmt. Die beiden Seitenwände 56, 57 sind durch eine Kopfplatte 61 zueinander auf Abstand gehalten.In the upper end region of the load arm 25, a bearing bush 52 is provided which receives a radial bearing 53 by which a pivot pin 54 is rotatably mounted about a pivot axis 55 to the load arm 25. The carrier 31 has at least a first side wall 56 and a second side wall 57, which are preferably spaced apart parallel to one another. The first side wall 56 forms an outer side of the carrier 31. The second side wall 57 forms an inner side of the carrier 31. A support arm holder 58 is provided on this second side wall 57, which supports the support arm 34 pivotably about a bearing axis 35, 36. The two side walls 56, 57 are kept at a distance from one another by a head plate 61.

Der Träger 31 ist entfernt zum Schwenkbolzen 54 durch einen Lagerbolzen 63 mit dem Führungsarm 27 verbunden. Dadurch ist der Führungsarm 27 schwenkbar um die eine Lagerachse 64 des Lagerbolzens 63 gelagert. Durch die Aufnahme des Trägers 31 über die Schwenkbolzen 54 und Lagerbolzen 63 kann der Träger 31 während dem Anheben und Senken der Hebevorrichtung 24 horizontal ausgerichtet werden.The carrier 31 is connected to the guide arm 27 at a distance from the pivot pin 54 by a bearing pin 63. As a result, the guide arm 27 is mounted pivotably about one bearing axis 64 of the bearing pin 63. By receiving the carrier 31 via the pivot pins 54 and bearing pins 63, the carrier 31 can be aligned horizontally while the lifting device 24 is being raised and lowered.

Die Einstellvorrichtung 51 wirkt gemäß der bevorzugten Ausführungsform zwischen dem Schwenkbolzen 54 und dem Träger 31. Alternativ kann die Einstellvorrichtung 51 auch am Lagerbolzen 63 vorgesehen sein. Ebenso kann die Einstellvorrichtung 51 sowohl am Schwenkbolzen 54 als auch am Lagerbolzen 53 vorgesehen sein. Der Aufbau der Einstellvorrichtung bleibt bei den alternativen Ausführungsformen gleich.According to the preferred embodiment, the adjusting device 51 acts between the pivot pin 54 and the carrier 31. Alternatively, the adjusting device 51 can also be provided on the bearing pin 63. The adjusting device 51 can likewise be provided both on the pivot pin 54 and on the bearing pin 53. The construction of the adjustment device remains the same in the alternative embodiments.

Die Einstelleinrichtung 51 umfasst eine Ausgleichsplatte 66, welche in einer Zentrieraufnahme 67 in der Seitenwand 56 positioniert ist. Dies ist in Figur 4 in einer Seitenansicht dargestellt. Die Zentrieraufnahme 67 in der Seitenwand 56 weist eine V- oder wannenförmige Kontur 71 auf, die sich in Kraftrichtung gemäß Kraft F1 verjüngt. Die Zentrieraufnahme 67 kann trapezförmig ausgestaltet sein. Eine untere Seitenkante 72 der trapezförmigen Zentrieraufnahme 67 ist kürzer als die gegenüberliegende beziehungsweise obere Seitenkante 73. Die Ausgleichsplatte 66 weist bevorzugt eine komplementäre Außenkontur auf. Bei einer auf die Tragarme 34 wirkenden Belastung stützt sich der V- oder wannenförmige Bereich der Zentrieraufnahme 67 an dem komplementären Bereich der Ausgleichsplatte 66 ab, welcher wiederum die Kraft auf den Schwenkbolzen 55 überträgt.The adjusting device 51 comprises a compensating plate 66 which is positioned in a centering receptacle 67 in the side wall 56. This is in Figure 4 shown in a side view. The centering receptacle 67 in the side wall 56 has a V-shaped or trough-shaped contour 71 which tapers in the direction of force according to force F1. The centering receptacle 67 can be designed trapezoidal. A lower side edge 72 of the trapezoidal centering receptacle 67 is shorter than the opposite or upper side edge 73. The compensating plate 66 preferably has a complementary outer contour. In the event of a load acting on the support arms 34, the V-shaped or trough-shaped area of the centering receptacle 67 is supported on the complementary area of the compensating plate 66, which in turn transmits the force to the pivot bolt 55.

Die Ausgleichsplatte 66 umfasst eine Bohrung 75, in der ein Ende des Schwenkbolzens 54 eingreift, sofern die Ausgleichsplatte 66 in der Zentrieraufnahme 67 positioniert ist.The compensating plate 66 comprises a bore 75 in which one end of the pivot pin 54 engages, provided that the compensating plate 66 is positioned in the centering receptacle 67.

Der Schwenkbolzen 54 weist an seiner Stirnseite zumindest eine Bohrung 77 auf. Die Ausgleichsplatte 66 weist ebenfalls zumindest eine Bohrung 78 auf. Außerhalb der Ausgleichsplatte 76 ist zumindest eine weitere Bohrung 79 in der Seitenwand 56 vorgesehen.The pivot pin 54 has at least one bore 77 on its end face.

Des Weiteren ist bevorzugt vorgesehen, dass zur Fixierung der Ausgleichsplatte 66 zur Haltevorrichtung 81 zumindest ein lösbares Halteelement 83, insbesondere eine Schraube, vorgesehen ist, welche in die zumindest eine Bohrung 78 eingreift. Vorteilhafterweise ist zumindest ein lösbares Fixierelement 84, insbesondere eine Schraube, vorgesehen, welche in zumindest eine Bohrung 77 des Schwenkbolzens 55 eingreift. Dadurch wird ermöglicht, dass die Einstelleinrichtung 51 eine feste Verbindung zwischen dem Träger 31 und der Hebevorrichtung 24 ermöglicht.the Figure 3 FIG. 11 shows a sectional view of a holding device 81 of the setting device 51, which is shown in an enlarged side view in FIG Figure 5 is shown. This holding device 81 is designed as a holding plate which is firmly connected to the side wall 56 by at least one detachable fastening element 82, in particular a screw, in that the at least one fastening element 82 engages in the bore 79. Furthermore, provision is preferably made for at least one releasable holding element 83, in particular a screw, which engages in the at least one bore 78, to be provided to fix the compensating plate 66 to the holding device 81. At least one detachable fixing element 84, in particular a screw, is advantageously provided, which engages in at least one bore 77 of the pivot bolt 55. This makes it possible for the adjusting device 51 to enable a fixed connection between the carrier 31 and the lifting device 24.

Die Seitenwände 56, 57 sind senkrecht zur Schwenkachse 55 ausgerichtet. Der Schwenkbolzen 54 und der Lagerbolzen 63 sind jeweils in einer Durchbrechung 62 in der Seitenwand 56, 57 gelagert, sofern keine Einstellvorrichtung 51 vorgesehen ist. Die Bohrung 75 in der Ausgleichsplatte 66 ist derart innerhalb der Ausgleichsplatte 66 ausgerichtet, dass der Abstand X gemäß Figur 3 eingenommen werden kann. Der Abstand X entspricht einem Abstand, welcher durch die Bezugsfläche 86 der Ausgleichsplatte 66 und einer Längsachse 87 der Bohrung 75 bestimmt ist, wie aus Figur 6a hervorgeht.The ones in the Figures 3 to 5 Adjusting device 51 shown enables the carrier 31 to be adjusted to the lifting device 24 in a zero position. The side walls 56, 57 are oriented perpendicular to the pivot axis 55. The pivot pin 54 and the bearing pin 63 are each mounted in an opening 62 in the side wall 56, 57 if no adjusting device 51 is provided. The bore 75 in the compensating plate 66 is aligned within the compensating plate 66 in such a way that the distance X according to FIG Figure 3 can be taken. The distance X corresponds to a distance which is determined by the reference surface 86 of the compensating plate 66 and a longitudinal axis 87 of the bore 75, as shown in FIG Figure 6a emerges.

Sofern nunmehr der Tragarm 34 bei der Verwendung einer Ausgleichsplatte 66 für eine Nullposition sich in Richtung auf den Boden neigt und unterhalb der Horizontalen liegt, kann die Ausgleichsplatte 66 gemäß Figur 4a ausgewechselt und durch eine Ausgleichsplatte 66 gemäß Figur 6b eingesetzt werden. Bei dieser Ausgleichsplatte 66 ist ein Abstand A zwischen der Bezugsfläche 86 und der Längsachse 87 der Bohrung 75 vorgesehen, welcher im Abstand kleiner als der Abstand X ist. Dadurch wird der Träger 31 in eine Richtung gemäß Pfeil N geschwenkt, wobei die Seitenwand 57 zum Schwenkbolzen 54 eine Art Drehlager bildet, um die Schwenkbewegung des Trägers 31 zum Schwenkbolzen 55 zu bewirken.If, when using a compensation plate 66 for a zero position, the support arm 34 now inclines in the direction of the floor and lies below the horizontal, the compensation plate 66 can according to FIG Figure 4a replaced and replaced by a compensation plate 66 according to Figure 6b can be used. In this compensating plate 66, a distance A is provided between the reference surface 86 and the longitudinal axis 87 of the bore 75, which distance is smaller than the distance X. As a result, the carrier 31 is pivoted in a direction according to arrow N, the side wall 57 to the pivot pin 54 forming a type of pivot bearing in order to bring about the pivoting movement of the carrier 31 to the pivot pin 55.

Der Austausch der Ausgleichsplatte 66 erfolgt dahingehend, dass die an der Halteeinrichtung 81 vorgesehenen Befestigungselemente 82, Halteelemente 83 und Fixierelemente 84 gelöst werden sowie die Halteplatte entnommen wird. Darauffolgend wird die Ausgleichsplatte 66 aus der Zentrieraufnahme 67 herausgenommen und die gewünschte neue Ausgleichsplatte 66 wiederum auf den Schwenkbolzen 54 aufgesetzt und in die Zentrieraufnahme 67 eingesetzt. Die Halteeinrichtung 81 wird mit dem zumindest einen Befestigungselement 82, Halteelement 83 und Fixierelement 84 wiederum fixiert. Die neue Ausrichtung des Tragarms 34 ist fixiert.The compensation plate 66 is exchanged to the effect that the fastening elements 82, holding elements 83 and fixing elements 84 provided on the holding device 81 are released and the holding plate is removed. The compensating plate 66 is then removed from the centering receptacle 67 and the desired new compensating plate 66 is again placed on the pivot pin 54 and inserted into the centering receptacle 67. The holding device 81 is in turn fixed with the at least one fastening element 82, holding element 83 and fixing element 84. The new alignment of the support arm 34 is fixed.

Sofern ausgehend von der Einstellvorrichtung 51 mit einer Nullposition das Ende des Tragarmes 34 oberhalb einer Horizontalen liegt, ist es erforderlich, das freie Ende des Tragarms 34 abzusenken. In einem solchen Fall kann eine Ausgleichsplatte 66 gemäß Figur 6c verwendet werden, bei welcher der Abstand B zwischen der Bezugsfläche 86 und der Längsachse 86 der Bohrung 75 größer als der Abstand X ist. Daraufhin wird der Träger 31 in Richtung Pfeil O geneigt und das freie Ende des Tragarms 34 abgesenkt.If, starting from the setting device 51 with a zero position, the end of the support arm 34 is above a horizontal line, it is necessary to lower the free end of the support arm 34. In such a case, a compensation plate 66 according to FIG Figure 6c can be used in which the distance B between the reference surface 86 and the The longitudinal axis 86 of the bore 75 is greater than the distance X. The carrier 31 is then inclined in the direction of arrow O and the free end of the support arm 34 is lowered.

Die Einstelleinrichtung 51 wird bevorzugt mit mehreren Ausgleichsplatten 66 bereitgestellt, die unterschiedliche Abstände zwischen der Bezugsfläche 86 und der Längsachse 87 aufweisen, um eine individuelle Einstellung und Anpassung der Tragarme 34 zu ermöglichen.The adjustment device 51 is preferably provided with a plurality of compensating plates 66 which have different distances between the reference surface 86 and the longitudinal axis 87 in order to enable the support arms 34 to be individually adjusted and adapted.
