Description

Hydraulische Hebebühne, insbesondere Motorradhebebühne Hydraulic lifting platform, in particular motorcycle lifting platform
Die vorliegende Erfindung betrifft eine hydraulische Hebebüh¬ ne, inbesondere eine Motorradhebebühne, welche ein Parallelo¬ grammchassis aufweist, wobei an einem der beiden parallelen Hub¬ arme ein am Unterchassis abgestützter Hydraulikzylinder angelenkt ist .The present invention relates to a hydraulic lifting platform, in particular a motorcycle lifting platform, which has a parallelogram chassis, a hydraulic cylinder supported on the lower chassis being articulated on one of the two parallel lifting arms.
Derartige Hebebühnen sind aus dem Stand der Technik bekannt. Ein Beispiel dafür ist in Fig. 2 der beigefügten Zeichnung darge¬ stellt. Die Druckkraft des Hydraulikzylinders, die bei Hebebüh¬ nen der gattungsgemäßen Art bis zu ca. 3 t betragen kann, wird hier vollständig in das Unterchassis abgeleitet. Dieses sowie auch der betroffene Hubarm müssen dementsprechend stark dimensio¬ niert werden, um diese Kräfte aufnehmen zu können. Das führt zu einem ungünstigen Eigengewicht/Hubkraft-Verhältnis, wodurch diese Bühnen in der Regel als stationäre Einrichtungen Werkstätten vor¬ behalten sind.Such lifts are known from the prior art. An example of this is shown in FIG. 2 of the accompanying drawing. The pressure force of the hydraulic cylinder, which can be up to approx. 3 t in the case of lifting platforms of the generic type, is here completely diverted into the lower chassis. This, as well as the lifting arm concerned, must accordingly be greatly dimensioned in order to be able to absorb these forces. This leads to an unfavorable dead weight / lifting force ratio, as a result of which these stages are generally reserved as workshops for stationary facilities.
Weiterhin nachteilig auf das Eigengewicht/Hubkraft-Verhältnis wirkt sich auch aus, daß der zweite Hubarm über das Oberchassis von dem durch den Hydraulikz linder beaufschlagten Hubarm mitge¬ zogen wird. Diese Konstruktion würde bei großen zu hebenden La¬ sten und aus Gründen der Eigengewichtsreduzierung schwach dimen¬ sionierten Bauteilen der Hebebühne zwangsläufig zu Klemmungen des Parallelogrammchassis führen. Bekannte Hebebühnen der hier in Frage kommenden Art haben daher aus den oben genannten Gründen ein Eigengewicht, das zwi¬ schen ca. 140 bis über 200 kg liegt, wobei das Hebevermögen etwa bei 400 kg liegt.Another disadvantageous effect on the dead weight / lifting force ratio is that the second lifting arm is pulled along via the upper chassis by the lifting arm acted upon by the hydraulic cylinder. This construction would inevitably lead to clamping of the parallelogram chassis in the case of large loads to be lifted and, for reasons of weight reduction, weakly dimensioned components of the lifting platform. Known lifts of the type in question here therefore have, for the reasons mentioned above, their own weight, which is between approximately 140 to over 200 kg, the lifting capacity being approximately 400 kg.
Aufgabe der vorliegenden Erfindung ist es, eine hydraulische Hebebühne, insbesondere eine Motorradhebebühne, der gattungsge¬ mäßen Art zur Verfügung zu stellen, die ein wesentlich besseres Eigengewicht/Hubkraft-Verhältnis aufweist als die aus dem Stand der Technik bekannten, vergleichbaren Hebebühnen.The object of the present invention is to provide a hydraulic lifting platform, in particular a motorcycle lifting platform, of the generic type which has a substantially better dead weight / lifting force ratio than the comparable lifting platforms known from the prior art.
Diese Aufgabe wird erfindungsgemäß mittels einer gattungsge¬ mäßen Hebebühne dadurch gelöst, daß der Hydraulikzylinder an ei¬ nen Anlenkpunkt unterhalb der Schwenkachse des Hubarmes an die¬ sen angreift, der dazu in diesem Bereich eine nach unten gerich¬ tete Auskragung aufweist, durch die ein günstiger Hebelarm für die Kraftübertragung des Hydraulikzylinders zur Verfügung steht. Weiterhin ist eine den Abstützpunkt des Hydraulikzylinders am Un- terchassis mit dem Hubarm verbindende Zugstrebenanordnung vorge¬ sehen, deren Anlenkpunkt am Hubarm mit dessen Schwenkachse ko¬ axial 1 iegt .This object is achieved according to the invention by means of a generic lifting platform in that the hydraulic cylinder engages at a pivot point below the pivot axis of the lifting arm, which for this purpose has a downward projection in this area, through which a more favorable Lever arm for the power transmission of the hydraulic cylinder is available. Furthermore, a tension strut arrangement connecting the support point of the hydraulic cylinder on the lower chassis to the lifting arm is provided, the articulation point of which on the lifting arm is coaxially 1 with its pivot axis.
Durch die am Hubarm vorgesehene Auskragung ist ein sehr gün¬ stiger Hebelarm für die Übertragung der Hubkraft des Hydraulik¬ zylinders auf den Hubarm gegeben. Um den Ausgangspunkt dieser Hubkraft im Unterchassis zu entlasten, und um eine U lenkung von horizontaler in vertikale Bewegung zu ermöglichen, ist eine Zug¬ strebenanordnung von der Linie der Schwenkachse des Hubarmes zum Ausgang der Hubkraft am Zylinderfuß vorgesehen. Die Überlagerung dieser Punkte, d.h. , die Aufnahme des Zylinderfußes im Unterchas- sis und der Endpunkt der Zugstrebenanordnung bewirkt, daß die Hubkraft durch äquivalente Zugkraft eine Umlenkung um die Schwenkachse erfährt. In dieser Anordnung der Elemente wird die Hubkraft des Zylinders neutralisiert, so daß das Unterchassis nicht belastet wird. Dieses sowie auch die Hubarme können auf¬ grund der erfindungsgemäßen Anordnung schwächer und damit ge¬ wichtssparend dimensioniert werden.The projection provided on the lifting arm provides a very favorable lever arm for the transmission of the lifting force of the hydraulic cylinder to the lifting arm. In order to relieve the starting point of this lifting force in the lower chassis and to enable a deflection from horizontal to vertical movement, a tension strut arrangement from the line of the pivot axis of the lifting arm to the output of the lifting force at the cylinder base is provided. The superimposition of these points, ie the inclusion of the cylinder base in the lower chassis and the end point of the tension strut arrangement means that the lifting force is deflected about the pivot axis by equivalent tensile force. In this arrangement of the elements, the lifting force of the cylinder is neutralized, so that the lower chassis is not charged. Because of the arrangement according to the invention, this and the lifting arms can be dimensioned to be weaker and thus to save weight.
In weiterer Ausgestaltung der Erfindung weist der zweite, al¬ so nicht vom Hydrauli zylinder beaufschlagte Hubarm, in analoger Weise zum ersten Hubarm eine Auskragung mit einem von seiner Schwenkachse gleich beabstandeten Anlenkpunkt auf. An diesen An¬ lenkpunkt greift ein Ende einer spannbaren Zugstange an, deren anderes Ende an den Anlenkpunkt der Auskragung des ersten Hubarms angrei ft .In a further embodiment of the invention, the second lifting arm, which is not acted upon by the hydraulic cylinder, has a projection in a manner analogous to the first lifting arm, with a pivot point equally spaced from its pivot axis. One end of a tensionable pull rod engages this articulation point, the other end of which engages the articulation point of the projection of the first lifting arm.
Aufgrund der Spannbarkeit der Zugstange kann eine Vorspannung erzeugt werden, die bewirkt, daß das Parallelogrammchassis auch bei größeren Lasten gleichmäßig bewegt wird. Klemmungen des Pa¬ rallelogramms sind auf diese Weise ausgeschlossen, so daß eine stärkere Dimensionierung der Bühnenbauteile aus diesem Grunde nicht erforderlich ist.Due to the tension of the drawbar, a preload can be generated, which causes the parallelogram chassis to move evenly with larger loads. Clamps of the parallelogram are excluded in this way, so that a stronger dimensioning of the stage components is not necessary for this reason.
Die erfindungsgemäße Lösung gestattet die Herstellung einer Hebebühne, die im wesentlichen lediglich die Kräfte der zu heben¬ den Last aufzunehmen hat, und damit entsprechend schwach dimen¬ sioniert werden kann. Damit ist ein Eigengewicht/Hubkraft-Ver¬ hältnis von bis zu etwa 1/6 möglich.The solution according to the invention permits the production of a lifting platform which essentially only has to take up the forces of the load to be lifted and can therefore be dimensioned correspondingly weakly. This allows a dead weight / lifting force ratio of up to about 1/6.

Die erfindungsgemäße Hebebühne besteht, wie bekannte Hebe¬ bühnen auch, aus einem Unterchassis 3, einem Oberchassis 16 und zwei parallel geführten Hubarmen 4 und 10, die in den Punkten 7 und 17 bzw. 12 und 18 am Unterchassis 3 bzw. Oberchassis 16 schwenkbar angelenkt sind.The lifting platform according to the invention, like known lifting platforms, consists of a lower chassis 3, an upper chassis 16 and two parallel lifting arms 4 and 10, which are pivotally articulated at points 7 and 17 or 12 and 18 on the lower chassis 3 or upper chassis 16 are.
Die Konstruktion der Hubarme 4 und 10 geht aus den Fig. 6.1 , 5.2 bzw. 7.1 , 7.2 hervor. Beide Hubarme haben zwei Längsprofile 19, die durch zwei Querprofile 20 starr miteinander verbunden sind. An den beiden Enden der Längsträger sind jeweils Lageraugen 7, 17 bzw. 12, 18 zur Aufnahme der dazugehörigen Schwenkachsen vorgesehen . Mit dem Querprofil 20 des Hubarmes 4 sind zwei parallel an¬ geordnete Hubbleche 9 starr verbunden, die nach unten auskragen, was insbesondere aus Fig. 6.2 hervorgeht. Etwa am tiefsten Punkt dieser Auskragung ist ein Lagerbolzen 8 vorgesehen, der beide Hubbleche 9 durchsetzt. Oberhalb dieses Bolzens 8 sind an den Hubblechen 9 koaxial zu den Lageraugen 7 weitere Lagerbolzen 6 vorgesehen .The construction of the lifting arms 4 and 10 is shown in FIGS. 6.1, 5.2 and 7.1, 7.2. Both lifting arms have two longitudinal profiles 19 which are rigidly connected to one another by two transverse profiles 20. Bearing eyes 7, 17 and 12, 18 are provided on the two ends of the longitudinal beams for receiving the associated pivot axes. Two parallel lifting plates 9, which project downward, are rigidly connected to the transverse profile 20 of the lifting arm 4, which protrudes downwards, which is particularly evident from FIG. 6.2. Approximately at the lowest point of this projection, a bearing pin 8 is provided which passes through both lifting plates 9. Above this bolt 8 7 further bearing bolts 6 are provided on the lifting plates 9 coaxially to the bearing eyes.
An das Querprofil 20 des Hubarmes 10 ist mittig ein Hubblech 9 angeschweißt, das ebenfalls nach unten auskragt, und etwa im tiefsten Punkt von einem Lagerbolzen 11 durchsetzt ist. Der Ab¬ stand 15 zwischen dem Lagerbolzen 11 und einer zwischen den La¬ geraugen 12 gedachten Linie ist gleich dem Abstand 15 zwischen dem Lagerbolzen 8 und einer zwischen den Lageraugen 7 gedachten Linie .A lifting plate 9 is welded in the middle to the transverse profile 20 of the lifting arm 10, which also protrudes downward and is penetrated by a bearing pin 11 at about the lowest point. The distance 15 between the bearing pin 11 and a line between the bearing eyes 12 is equal to the distance 15 between the bearing pin 8 and a line between the bearing eyes 7.
Auf das Unterchassis 3 sind U-förmige Lagerböcke 21 aufge¬ schweißt, die zwischen ihren Wangen die Längsprofile 19 der Hub¬ arme 4 und 10 aufnehmen. Die Anlenkung der Hubarme 4, 10 erfolgt durch Schwenkachsen, die durch die Lageraugen 7 bzw. 12 und in den Wangen der Lagerböcke 21 entsprechend vorgesehene Bohrungen eingesteckt werden.U-shaped bearing blocks 21 are welded onto the lower chassis 3 and accommodate the longitudinal profiles 19 of the lifting arms 4 and 10 between their cheeks. The articulation of the lifting arms 4, 10 is carried out by swivel axes which are inserted through the correspondingly provided bores through the bearing eyes 7 and 12 and in the cheeks of the bearing blocks 21.
Der Hydraulikzylinder 1 ist am Punkt 2 am Unterchassis 3 abgestützt. An eben diesem Punkt 2 greifen zwei parallel verlau¬ fende Zugstreben 5 an, deren anderes Ende durch die Lagerbolzen 6 an den beiden Hubblechen 9 des Hubarmes 4 gehaltert sind. Das Pleuelauge des Hubzylinderkolbens sitzt zwischen den beiden Hub¬ blechen 9 auf dem Lagerbolzen 8.The hydraulic cylinder 1 is supported at point 2 on the lower chassis 3. At this point 2, two parallel struts 5 engage, the other end of which is supported by the bearing bolts 6 on the two lifting plates 9 of the lifting arm 4. The connecting rod eye of the lifting cylinder piston sits between the two lifting plates 9 on the bearing pin 8.
Auf dem Lagerbolzen 8 sind auch die Enden einer Zugstange 14 gelagert. Diese Zugstange 14 besteht, was aus den Figuren nicht hervorgeht, aus zwei parallel geführten Streben. Die Enden dieser beiden Streben liegen außen an den Hubblechen 9 an.The ends of a pull rod 14 are also mounted on the bearing pin 8. This pull rod 14, which does not appear from the figures, consists of two parallel struts. The ends of these two struts rest on the lifting plates 9.
ERSATZBLATT Die Zugstange 14 ist in zwei Längsabschnitte geteilt, wobei diese beiden Längsabschnitte durch eine verstellbare Bolzen¬ mutteranordnung 22 miteinander verbunden sind. Der zum Hubarm 10 führende Längsabschnitt der Zugstange 14 ist über den Lagerbolzen 11 an das Hubblech 13 angelenkt. Dabei liegen die Enden der bei¬ den Streben links und rechts am Hubblech 13 an, der Abstand der Streben der Zugstange 14 ist also in diesem Längsabschnitt ge¬ ringer als der der Streben im anderen Längsabschnitt der Hub¬ stange 14.REPLACEMENT LEAF The pull rod 14 is divided into two longitudinal sections, these two longitudinal sections being connected to one another by an adjustable bolt nut arrangement 22. The longitudinal section of the pull rod 14 leading to the lifting arm 10 is articulated to the lifting plate 13 via the bearing pin 11. The ends of the two struts are on the left and right of the lifting plate 13, so the distance between the struts of the pull rod 14 is smaller in this longitudinal section than that of the struts in the other longitudinal section of the lifting rod 14.
Über die Rohr-Mutter-Anordnung 22 der Zugstange 14 kann durch entsprechend festes Anziehen der Mutter eine Vorspannung zwischen den beiden Hubstangen 4 und 10 hergestellt werden. Dadurch wird gewährleistet, daß sich die beiden Hubarme 4, 10 auch bei grös- seren Lasten völlig parallel zueinander bewegen.A preload can be produced between the two lifting rods 4 and 10 via the tube-nut arrangement 22 of the pull rod 14 by tightening the nut accordingly. This ensures that the two lifting arms 4, 10 move completely parallel to one another, even with larger loads.
Der Hydraulikzylinder 1 hat etwa eine Hubkraft von 2,7 t. Diese wird bei der erfindungsgemäßen Hebebühne nicht in das Un¬ terchassis 3 abgeführt, sondern über die Zugstreben 5 auf die Hubbleche 9 abgeleitet. Die Belastung der Bauteile der Hebebühne durch den Hydraulikzylinder wird damit praktisch neutralisiert. In der Folge kann eine erfindungsgemäße Hebebühne sehr leicht ge¬ baut werden. In einem Test konnten 760 kg bei einem Eigengewicht der Hebebühne von 82 kg problemlos gehoben werden. The hydraulic cylinder 1 has a lifting capacity of approximately 2.7 t. In the lifting platform according to the invention, this is not discharged into the subchassis 3, but is derived via the tension struts 5 onto the lifting plates 9. The load on the components of the lift by the hydraulic cylinder is practically neutralized. As a result, a lifting platform according to the invention can be built very easily. In one test, 760 kg could be lifted without problems with a lifting weight of 82 kg.
