Abstract
Description
Die Erfindung bezieht sich auf eine flachbauende Hebebühne mit einer Hubplatte, welche an einem am Grundrahmen schwenkbar abgestützten Hubarm gelenkig angeschlossen ist, wobei der Hubarm über einen am Hubarm angreifenden Antrieb um eine Anlenkachse am Grundrahmen verschwenkbar ist und wobei der Antrieb über einen Lenker mit einer Anlenkstelle oberhalb der Schwenkachse des Hubarmes am Grundrahmen mit dem Hubarm verbunden ist, welche bei eingefahrener Position des Hubarmes höher liegt als die Angriffstelle des Antriebes am Lenker.The invention relates to a flat lift a lifting plate which is supported on a pivotable on the base frame Lift arm is articulated, the lift arm via a drive engaging the lifting arm around a pivot axis is pivotable on the base frame and with the drive over a handlebar with a pivot point above the pivot axis of the lifting arm on the base frame is connected to the lifting arm, which with the lifting arm in the retracted position is higher than the point of attack of the drive on the handlebar.
Hebebühnen, welche so ausgebildet sein sollen, daß bei eingefahrener Position aer Plattform bzw. Hubplatte keine über die Hubplatte nach oben vorragende Teile verbleiben, sind beispielsweise aus der WO 89/11437 oder der WO 89/11438 bekanntgeworden. Bei diesen bekannten Einrichtungen handelt es sich um verfahrbare Einrichtungen, mit welchen ein Anheben eines Kraftfahrzeuges um einen vorbestimmten Hub, beispielweise zum Reifenwechsel, ermöglicht wird. Die bekannten Konstruktionen benötigen einen relativ großen Antrieb, wenn aus der Strecklage des Antriebes heraus bereits Lasten angehoben werden sollen. Üblicherweise wird mit derartigen Einrichtungen eine Last erst nach einem vorbestimmten Hub ergriffen und angehoben.Lifts, which should be designed so that when retracted Position on the platform or lifting plate is not above the Lifting plate protruding parts remain, for example from WO 89/11437 or WO 89/11438. These known devices are around movable devices with which a lifting of a Motor vehicle by a predetermined stroke, for example Tire change is made possible. The well-known constructions need a relatively large drive when out of stretch loads have already been lifted out of the drive should. Usually such a device Load picked up and lifted only after a predetermined stroke.
Eine weitere Hebebühne, wie sie aus der DE-OS 36 04 456 bekanntgeworden ist, erlaubt es mit hydraulischen Zylinderkolbenaggregaten, welche im wesentlichen parallel zu einer Bodenebene angeordnet sind, über Scheren eine Plattform anzuheben. Bei derartigen Scherenhebebühnen ist die Krafteinleitung in einer ersten Phase der Ausfahrbewegung relativ ungünstig, sodaß eine relativ hohe Bauhöhe erforderlich ist, um auch von der eingefahrenen Position weg bereits Lasten anheben zu können. Analoges gilt für die mit Parallelogrammlenkern geführten Hubplatten, wie sie aus der US-PS 3 865 214 und der US-PS 5 040 637 bekanntgeworden sind. Auch bei derartigen Hubplatten, deren Parallelführung zum Boden durch Parallelogrammlenker sichergestellt wird, ist die Krafteinleitung in einem ersten Teilbereich der Hubbewegung überaus ungünstig, sodaß große Lasten nur dann angehoben werden können, wenn eine relativ große Bauhöhe und ein überdimensionierter Antrieb vorgesehen wird.Another lifting platform as it became known from DE-OS 36 04 456 with hydraulic cylinder piston units, which is essentially parallel to a floor plane are arranged to lift a platform via scissors. With scissor lifts of this type, the introduction of force is in a first phase of the extension movement relatively unfavorable, so that a relatively high height is required to also from to be able to lift loads from the retracted position. The same applies to those guided with parallelogram links Lifting plates, such as those from US Pat. No. 3,865,214 and the US PS 5,040,637 have become known. Even with such lifting plates, their parallel guidance to the floor by parallelogram handlebars is ensured, the application of force is in one first part of the stroke movement extremely unfavorable, so large loads can only be lifted if a relative large height and an oversized drive provided becomes.
Die Erfindung zielt nun darauf ab, eine flachbauende Hebebühne der eingangs genannten Art zu schaffen, bei welcher mit wesentlich geringerer Bauhöhe und kleinernen Antriebsaggregaten von der voll eingefahrenen Stellung weg bereits große Lasten sicher angehoben werden können. Die flache Bauweise soll hiebei insbesondere ermöglichen, daß eine derartige Hebebühne auch nachträglich in Bodenkonstruktionen bzw. Deckenkonstruktionen einer Werkstätte eingebaut werden kann, ohne daß hiefür eine Verstärkung des Bodens bzw. der Decke erforderlich ist, und ohne daß Durchbrüche in Boden oder Decke erforderlich sind um den für die Antriebsaggregate benötigten Platz zu schaffen.The invention now aims to provide a low-profile lift to create the type mentioned, in which with essential lower overall height and smaller drive units already heavy loads away from the fully retracted position can be safely lifted. The flat design is said to be in particular enable such a lifting platform also subsequently in floor constructions or ceiling constructions a workshop can be installed without this reinforcement of the floor or ceiling is required, and without the need for openings in the floor or ceiling in order to create the space required for the drive units.
Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Hebebühne im wesentlichen darin, daß der Lenker als zweiarmiger schwenkbarer Hebel nach Art eines Kniehebels ausgebildet ist, dessen zwischen den freien Enden des zweiarmigen Hebels liegende Schwenkachse über wenigstens einen weiteren Lenker in Höhenrichtung schwenkbar am Grundrahmen abgestützt ist. Dadurch, daß der Antrieb über einen Lenker mit einer Anlenkstelle oberhalb der Schwenkachse des Hubarmes am Grundrahmen mit dem Hubarm verbunden ist, wird eine Art Kniehebel ausgebildet, wobei dann, wenn der Antrieb ausgefahren wird zunächst unter der Kniehebelwirkung dieses Lenkers eine erste Teilverschwenkung des Hubarmes vorgenommen wird. Die Übersetzung des Kniehebels erlaubt hier einen wesentlich kleiner bauenden Antrieb und dadurch eine flachere Konstruktion, wenn der Antrieb im Grundrahmen und unter der Hubplatte untergebracht werden soll. Dadurch, daß der Antrieb unterhalb der Anlenkstelle des Lenkers am Hubarm am Lenker angreift und dadurch, daß der gleiche Antrieb mit seinem anderen Ende am Hubarm angreift, Wird sichergestellt, daß die Anlenkstelle des Antriebes am Lenker aufgrund der Krafteinleitung immer in Richtung zum Grundrahmen beaufschlagt wird, wohingegen das andere Ende des Lenkers, welches oberhalb dieser Anlenkstelle am Hubarm angeschlagen ist bei einer Verschiebung der unteren Anlenkstelle des Lenkers in einer Richtung, welche im wesentlichen parallel zum Grundrahmen verlaufen kann, nach oben ausweicht, wodurch der erste Teil der Schwenkbewegung des Hubarmes eingeleitet wird. Eine derartige Kniehebelkonstruktion erlaubt somit eine wesentlich günstigere Krafteinleitung, sowie eine Übersetzung im ersten Teilbereich des Schwenkweges, wodurch insgesamt wesentlich flacher gebaut werden kann und mit kleineren Antriebsaggregaten das Auslangen gefunden wird. Der Antrieb kann hierbei bevorzugt von einem hydraulischen Zylinderkolbenaggregat gebildet werden, wobei naturgemäß auch andere Formen des Linearantriebes, wie beispielsweise Spindelantriebe od. dgl. ohne weiteres denkbar sind. Die Anlenkstelle des als Kniehebel wirksamen Lenkers an dem Antrieb wird aufgrund ihrer Lage immer in Anlage an den Grundrahmen gehalten, wenn der Antrieb betätigt wird. Diese Anlenkstelle kann aber auch in einem zur Bodenebene parallelen Langloch geführt sein oder durch Anschläge gegen ein Aufsteigen gesichert werden.To solve this problem, the lifting platform according to the invention essentially in that the handlebar as a two-armed pivotable lever is designed in the manner of a toggle lever, the one between the free ends of the two-armed lever Swivel axis in at least one other link Height direction is pivotally supported on the base frame. The fact that the drive via a handlebar with a pivot point above the swivel axis of the lifting arm on the base frame is connected to the lifting arm, a kind of toggle lever is formed, where when the drive is extended first under the toggle action of this handlebar a first partial pivoting the lifting arm is made. The translation of the The toggle lever allows a much smaller drive and therefore a flatter construction when the drive be accommodated in the base frame and under the lifting plate should. The fact that the drive below the pivot point of the Handlebar on the lifting arm on the handlebars and in that the engages the same drive with its other end on the lifting arm, It is ensured that the articulation point of the drive on Handlebar always in the direction of due to the application of force Base frame is applied, whereas the other end of the Handlebar, which struck the lifting arm above this articulation point is at a displacement of the lower articulation point the handlebar in a direction that is substantially parallel can run to the base frame, deviates upwards, whereby the first part of the pivoting movement of the lifting arm is initiated becomes. Such a toggle lever construction thus allows one much cheaper introduction of force, as well as a translation in the first section of the swivel path, which makes it essential overall can be built flatter and with smaller drive units the sufficiency is found. The drive can preferably from a hydraulic cylinder piston unit are formed, naturally other forms of the linear drive, such as, for example, spindle drives. Like. Are easily conceivable. The pivot point of the as Toggle lever effective handlebar on the drive is due to their Position always held in contact with the base frame when the drive is operated. This articulation point can also in be an elongated hole parallel to the floor level or secured against rising by stops.
Erfindungsgemäß ist nun die Ausbildung so getroffen, daß der Lenker als zweiarmiger schwenkbarer Hebel ausgebildet ist, dessen Schwenkachse über wenigstens einen weiteren Lenker in Höhenrichtung schwenkbar am Grundrahmen abgestützt ist. Prinzipiell genügt aufgrund der Lage der Anlenkstelle des Lenkers am Hubarm und am Antrieb in völlig eingefahrener Position, wenn das untere Ende des Lenkers gleitend im Grundrahmen geführt ist, um die gewünschte Kniehebelwirkung zu erzielen. Die Kniehebelwirkung und die Betriebssicherheit lassen sich aber durch eine schwenkbare Anlenkung wesentlich verbessern, wobei dadurch, daß wenigstens ein weiterer Lenker in Höhenrichtung schwenkbar am Grundrahmen abgestützt ist, über einen längeren Schwenkweg des Hubarmes die vorteilhafte Übersetzung des Kniehebelgetriebes zur Wirkung gelangt. According to the invention, the training is now such that the Handlebar is designed as a two-armed pivotable lever, whose pivot axis in at least one other link Height direction is pivotally supported on the base frame. In principle is sufficient due to the location of the linkage of the handlebar on the lifting arm and on the drive in a fully retracted position, if the lower end of the handlebars sliding in the base frame is performed to achieve the desired toggle effect. The toggle action and operational safety can be but significantly improved by a pivotable linkage, whereby in that at least one other handlebar in the height direction is pivotally supported on the base frame, via a longer swing path of the lifting arm the advantageous translation of the toggle lever gear comes into effect.
Um eine Parallelführung der Hubplatte zur Ebene des Grundrahmens zu gewährleisten, ist mit Vorteil die Ausbildung so getroffen, daß die Hubplatte mit einem zum Hubarm parallelen Lenker verbunden und zur Bodenebene parallel geführt ist.To guide the lifting plate parallel to the level of the base frame to ensure, the training is advantageously made so that the lifting plate with a parallel to the lifting arm Handlebar connected and guided parallel to the floor level.
Um sicherzustellen, daß bei Einschalten des Antriebes bei voll eingefahrener Position des Hubarmes die gewünschte Verschwenkung des Kniehebels und der Schwenkachse des als zweiarmiger Hebel ausgebildeten Kniehebels eintritt, ist mit Vorteil die Ausbildung so getroffen, daß die Anlenkstelle des zweiarmigen Hebels bei eingefahrener Position der Hubplatte oberhalb der Anlenkstelle für den Angriff des hydraulischen Zylinderkolbenaggregates liegt. Auf diese Weise wird eine Kinematik sichergestellt, bei welcher auch bei kleinbauendem und kleindimensioniertem Antrieb aus der voll eingefahrenen Position hohe Hebekräfte wirksam werden können.To ensure that when the drive is switched on at full retracted position of the lifting arm the desired pivoting of the toggle lever and the swivel axis of the two-armed Lever trained toggle lever occurs, is the advantage Training taken so that the articulation point of the two-armed Lever with the lifting plate in the retracted position above the Linkage point for the attack of the hydraulic cylinder piston unit lies. In this way, kinematics are ensured in which even with small-scale and small dimensions High drive from the fully retracted position Lifting forces can be effective.
Eine konstruktiv besonders kompakte Bauweise kann hiebei dadurch erzielt werden, daß der oder die Lenker zur Abstützung des zweiarmigen Hebels koaxial zur Schwenkachse des Parallelogrammlenkers der Hubplatte am Grundrahmen angelenkt ist (sind).This allows a particularly compact design achieved that the handlebar or the support of the two-armed lever coaxial to the pivot axis of the parallelogram link the lifting plate is articulated on the base frame (are).
Die Erfindung wird nachfolgend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert.The invention is described below with reference to a drawing schematically illustrated embodiment.
