Description
Die Erfindung betrifft eine mobile Hebebühne zum Heben und Senken von Lasten, Fahrzeugen oder dergleichen.The invention relates to a mobile lift for lifting and lowering loads, vehicles or the like.
Aus der
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine mobile Hebebühne zu schaffen, welche einen einfachen Aufbau einer Laufrollenverstelleinrichtung für eine seitliche Verfahrbarkeit der Hebebühne ermöglicht.The invention has for its object to provide a mobile lift, which allows a simple construction of a Laufrollenverstelleinrichtung for lateral mobility of the lift.
Diese Aufgabe wird durch eine mobile Hebebühne gelöst, bei der jede Laufrolle von einer am Grundgestell angeordneten Laufrollenverstelleinrichtung aufgenommen ist, durch welche die Laufrolle in der Fahrtrichtung einstellbar ist und die Laufrolle der Laufrollenverstelleinrichtung nur in vertikaler Richtung gegenüber dem Grundkörper aus der Lastaufnahmeposition in die Verfahrposition ausfahrbar ist, unabhängig von einer Bewegungsrichtung einer Verstelleinrichtung, die zum Ausfahren der Laufrolle auf die Laufrollenverstelleinrichtung wirkt. Durch diese Anordnung wird eine Unterbrechung einer mechanischen Kette zwischen der Betätigungseinrichtung und der Verstelleinrichtung einerseits und der Laufrollenverstelleinrichtung andererseits erzielt, auf welche die Verstelleinrichtung wirkt. Dadurch lässt sich eine ausschließlich vertikale Hubbewegung der Laufrollen beziehungsweise Ausfahrbewegung der Laufrollen gegenüber dem Grundgestell erzielen. Dadurch können die Laufrollen immer senkrecht zum Boden ausgerichtet sein.This object is achieved by a mobile lift, wherein each roller is received by a arranged on the base frame Laufrollenverstelleinrichtung by which the roller is adjustable in the direction of travel and the roller of Laufrollenverstelleinrichtung only in the vertical direction relative to the main body from the load receiving position in the travel position extendable is independent of a direction of movement of an adjustment, which acts to extend the roller on the Laufrollenverstelleinrichtung. By this arrangement, an interruption of a mechanical chain between the actuating device and the adjusting device on the one hand and the Laufrollenverstelleinrichtung other hand, on which the adjusting device acts. As a result, an exclusively vertical lifting movement of the rollers or extension movement of the rollers relative to the base frame can be achieved. As a result, the rollers can always be aligned perpendicular to the ground.
Bevorzugt umfasst die Verstelleinrichtung ein Gestänge mit einem am Grundgestell gelagerten Schwenkhebel, der zur Laufrollenverstelleinrichtung mechanisch entkoppelt ist, und durch eine Schwenkbewegung des Schwenkhebels ist eine vertikale Hubbewegung der Laufrollenverstelleinrichtung ansteuerbar. Dadurch kann aufgrund der Schwenkbewegung in einfacher Weise eine große Hebelkraft auf die Laufrollenverstelleinrichtung ausgeübt werden, so dass diese Laufrollenverstelleinrichtung gegenüber dem Grundgestell eine vertikale Hubbewegung durchführt und das Fahrwerk ausfährt. Durch die mechanische Entkopplung kann einerseits eine große Hebelkraft übertragen werden und andererseits die Schwenkbewegung des Schwenkhebels in eine ausschließliche vertikale Hubbewegung der Laufrolle umgesetzt werden.The adjusting device preferably comprises a linkage with a pivot lever mounted on the base frame, which is mechanically decoupled from the roller adjusting device, and a vertical lifting movement of the roller adjusting device can be controlled by a pivoting movement of the pivoting lever. As a result, due to the pivoting movement in a simple manner, a large leverage on the Caster adjustment be exercised, so that this Laufrollenverstelleinrichtung performs a vertical lifting movement relative to the base frame and the chassis extends. Due to the mechanical decoupling on the one hand, a large leverage can be transmitted and on the other hand, the pivotal movement of the pivot lever can be converted into an exclusive vertical lifting movement of the roller.
Die Betätigungsvorrichtung der mobilen Hebebühne leitet bevorzugt eine kreisbogenförmige Stellbewegung in das Gestänge ein, welche diese Stellbewegung auf den Schwenkhebel überträgt, wobei aufgrund der mechanischen Entkopplung zwischen dem Schwenkhebel und der Laufrollenverstelleinrichtung die vertikale Hubbewegung der Laufrollenverstelleinrichtung ansteuerbar ist. Dadurch kann trotz der Einleitung einer kreisbogenförmigen Stellbewegung in das Gestänge eine ausschließlich vertikale Ausfahrbewegung der Laufrollen gegenüber dem Grundgestell erzielt werden.The actuating device of the mobile lift preferably introduces a circular arc-shaped adjusting movement in the linkage, which transmits this adjusting movement to the pivot lever, wherein due to the mechanical decoupling between the pivot lever and the Laufrollenverstelleinrichtung the vertical lifting movement of the Laufrollenverstelleinrichtung is controlled. As a result, despite the initiation of a circular arc-shaped positioning movement in the linkage exclusively vertical extension movement of the rollers relative to the base frame can be achieved.
Bevorzugt ist vorgesehen, dass das Grundgestell U-förmig ausgebildet ist und zwei zueinander ausgerichtete Fußstützenaufnahmen aufweist und an jeder Außenseite der Fußstützenaufnahme die Laufrollenverstelleinrichtung vorgesehen ist. Dies ermöglicht, dass eine integrierte Positionierung der Laufrollen in der Fußstützenaufnahme nicht erforderlich ist. Durch die Anordnung außerhalb mittels der Laufrollenverstelleinrichtung können größere Raddurchmesser für die Laufrolle eingesetzt werden, wodurch ein geringerer Rollwiderstand ermöglicht wird. Darüber hinaus ist ermöglicht, dass die Fußstützenaufnahmen Fußstützen aufnehmen können, die vorzugsweise zu den Fußstützenaufnahmen teleskopierbar sind, um bei Bedarf eine größere Aufstandsfläche des Grundgestells zu erzielen.It is preferably provided that the base frame is U-shaped and has two mutually aligned Fußstützenaufnahmen and on each outer side of the Fußstützenaufnahme the Laufrollenverstelleinrichtung is provided. This allows integrated positioning of the rollers in the footrest mount not required. The arrangement outside by means of the Laufrollenverstelleinrichtung larger wheel diameter can be used for the roller, whereby a lower rolling resistance is made possible. In addition, it is possible that the footrest receptacles can accommodate footrests, which are preferably telescopic to the Fußstützenaufnahmen to achieve a larger footprint of the base frame if necessary.
Des Weiteren ist bevorzugt vorgesehen, dass die Laufrolle in der Laufrollenverstelleinrichtung einen Schwenkbereich von wenigstens 90° zwischen einer ersten und einer zweiten Laufrichtung aufweist und um eine vertikale Achse schwenkbar ist. Dadurch können die Laufrollen, die beispielsweise bezüglich deren Lauffläche parallel zur Fußstützenaufnahme in einer ersten Laufrichtung ausgerichtet sind, um 90° verdreht werden, so dass dann eine seitliche Verfahrbewegung der mobilen Hebebühne ermöglicht ist. Dadurch stehen die Laufrollen unabhängig der eingestellten Verfahrrichtung immer senkrecht zum Boden.Furthermore, it is preferably provided that the roller in the Laufrollenverstelleinrichtung has a pivoting range of at least 90 ° between a first and a second direction and is pivotable about a vertical axis. This allows the rollers, for example, with respect to the running surface parallel to Footrest recording are aligned in a first direction, are rotated by 90 °, so that then a lateral movement of the mobile lift is possible. As a result, the rollers are always perpendicular to the ground, regardless of the set travel direction.
Bevorzugt ist vorgesehen, dass die Laufrichtung der Laufrollen in der Lastaufnahmeposition des Grundgestells veränderbar ist. Das Grundgestell liegt dabei auf dem Untergrund auf. Die Laufrollen sind entlastet und können dann um 90° geschwenkt werden.It is preferably provided that the running direction of the rollers in the load-receiving position of the base frame is variable. The base frame rests on the ground. The rollers are unloaded and can then be swiveled by 90 °.
Vorteilhafterweise ist vorgesehen, dass jede Laufrichtung der Laufrolle mit einer lösbaren Arretiervorrichtung gesichert ist. Dadurch kann eine einmal eingestellte Fahrtrichtung beibehalten und gesichert sein. Die Arretiervorrichtung ist bevorzugt manuell lösbar und rastet bei der Ausrichtung der Laufrolle in der jeweiligen Laufrichtung selbständig ein und sichert die Position der Laufrolle.Advantageously, it is provided that each running direction of the roller is secured with a releasable locking device. This allows a once set direction to be maintained and secured. The locking device is preferably manually detachable and engages automatically in the alignment of the roller in the respective direction and secures the position of the roller.
Die Laufrollenverstelleinrichtung umfasst eine Laufrollenhalterung, durch welche die Laufrolle rotierend gelagert ist, sowie ein Führungselement, welches die Laufrollenhaltung aufnimmt und einen Führungsschacht, in dem das Führungselement in vertikaler Richtung auf und ab bewegbar geführt ist. Diese ineinander geschachtelte Anordnung mit der Laufrollenhalter in dem Führungselement und dem Führungselement in dem Führungsschacht ermöglicht eine einfache konstruktive Ausgestaltung für einen ausschließlich vertikalen Hub des Grundgestells beim Aus- und Einfahren des Fahrwerks. Zudem ist dadurch ein konstruktiv einfacher Aufbau gegeben.The roller adjusting device comprises a roller holder, through which the roller is rotatably mounted, and a guide member which receives the roller holder and a guide shaft in which the guide member is guided in the vertical direction movable up and down. This nested arrangement with the roller holder in the guide element and the guide element in the guide shaft allows a simple structural design for an exclusively vertical stroke of the base frame during extension and retraction of the chassis. In addition, this gives a structurally simple design.
Das Führungselement weist zumindest zwei, vorzugsweise einander gegenüberliegende Führungsflächen auf, durch welche das Führungselement verdrehgesichert in dem Führungsschacht angeordnet ist. Durch eine einfache geometrische Ausgestaltung des Führungselements können eine Längsführung bzw. Hubbewegung in dem Führungsschacht einerseits und eine verdrehgesicherte Führung andererseits ermöglicht sein.The guide element has at least two, preferably opposing guide surfaces through which the guide element is arranged secured against rotation in the guide shaft. By a simple geometric configuration of the guide element, a longitudinal guide or lifting movement in the guide shaft on the one hand and a rotation-secured guide on the other hand can be made possible.
Die Laufrollenhalterung ist bevorzugt in dem Führungselement um eine vertikale Achse drehbar angeordnet und weist an einem Lagerbock zur rotierenden Aufnahme der Laufrolle zumindest eine Gleitführungsfläche auf, welche um eine zur Laufrollenachse orthogonale Achse radial umlaufend ausgerichtet ist. Dies ermöglicht, dass nach dem Einsetzen der Laufrollenhalterung in das Führungselement eine Verdrehbewegung der Laufrolle um 90° in die jeweilige Laufrichtung durch die zumindest eine Gleitführungsfläche an dem Führungselement abgestützt ist.The roller holder is preferably in the guide element to a rotatably arranged vertical axis and has on a bearing block for rotatably receiving the roller at least one sliding guide surface which is aligned radially circumferentially about an axis orthogonal to the roller axis. This allows that after insertion of the roller holder in the guide element, a rotational movement of the roller is supported by 90 ° in the respective direction by the at least one sliding guide surface on the guide member.
Bevorzugt ist vorgesehen, dass das Führungselement einen quadratischen Querschnitt aufweist und die zumindest eine Gleitführungsfläche der Laufrollenhalterung sich an inneren Wandabschnitten der Führungsflächen des Führungselementes abstützt. Dadurch ist ermöglicht, dass die Laufrollenhalterung über die kreisrunden Gleitführungsflächen innerhalb des quadratischen Führungselementes während einer Rotationsbewegung um die vertikale Achse geführt wird.It is preferably provided that the guide element has a square cross-section and the at least one sliding guide surface of the roller holder is supported on inner wall portions of the guide surfaces of the guide element. This makes it possible that the roller holder is guided over the circular sliding guide surfaces within the square guide member during a rotational movement about the vertical axis.
Bevorzugt sind zwei mit Abstand zueinander angeordnete Gleitführungsflächen an der Laufrollenhalterung vorgesehen. Dadurch wird ein Verkippen der Laufrollenhalterung innerhalb des Führungselementes verhindert.Preferably, two spaced sliding guide surfaces are provided on the roller holder. This prevents tilting of the roller holder within the guide element.
Eine weitere bevorzugte Ausführungsform der Erfindung sieht vor, dass das Führungselement die Laufrollenhalterung vollständig mit Ausnahme eines bodenseitigen Laufflächenabschnitts der Lauffläche umgibt. Dadurch ist durch das Führungselement ein Fußschutz für eine Bedienperson während der Verfahrbewegung gegeben.A further preferred embodiment of the invention provides that the guide element completely surrounds the roller holder with the exception of a bottom-side tread portion of the tread. As a result, a foot protection for an operator during the movement is given by the guide element.
Des Weiteren ist bevorzugt vorgesehen, dass das Führungselement einen Deckel mit einer Ausnehmung aufweist, durch welche sich ein an dem Laufrollenhalter angeordnetes Stellelement erstreckt. Dies ermöglicht eine einfache Verstellmöglichkeit der Laufrolle durch die Betätigung des Stellelementes. Zudem ist durch die Ausnehmung gleichzeitig ersichtlich, in welche Laufrichtung die Laufrolle eingestellt ist, da das Stellelement und die Lauffläche der Laufrolle gleich ausgerichtet sind. Dies kann auch durch die Ausrichtung des Stellelementes, welches länglich ist, gegeben sein.Furthermore, it is preferably provided that the guide element has a cover with a recess through which a control element arranged on the roller holder extends. This allows a simple adjustment of the roller by the operation of the control element. In addition, it can be seen at the same time in the running direction of the roller is set by the recess, since the actuator and the tread of the roller are aligned the same. This can also be given by the orientation of the actuating element, which is elongated.
Bevorzugt ist das Stellelement an der Laufrollenhalterung als Bügel ausgebildet, wobei der Bügel vertikal ausgerichtete Führungsabschnitte aufweist, die an einer Stirnwand der Ausnehmung drehbar geführt sind. Dies ermöglicht eine weitere Lagesicherung der Laufrollenhalterung in dem Führungselement während der Verfahrbewegung als auch eine verkantungsfreie Verdrehung der Laufrolle aus einer Laufrichtung in die andere Laufrichtung.Preferably, the actuator is formed on the roller holder as a bracket, wherein the bracket vertically aligned guide sections has, which are rotatably guided on an end wall of the recess. This allows a further securing position of the roller holder in the guide element during the movement as well as a tilt-free rotation of the roller from one direction in the other direction.
Des Weiteren ist bevorzugt vorgesehen, dass die Stirnwand der Ausnehmung durch zwei einander gegenüberliegende Bogensegmente, vorzugsweise mit einem Winkel von 90°, gebildet ist, wobei die zwei Bogensegmente durch zwei dazwischen angeordnete kreisbogenförmige Vorsprünge begrenzt sind. Dadurch werden in einfacher Weise ein Anschlag zur Begrenzung der Drehbewegung und eine Führung des Stellelementes ermöglicht.Furthermore, it is preferably provided that the end wall of the recess is formed by two opposing arc segments, preferably at an angle of 90 °, wherein the two arc segments are bounded by two circular arc-shaped projections arranged therebetween. As a result, a stop for limiting the rotational movement and a guide of the actuating element are made possible in a simple manner.
Die Laufrollenhalterung weist vorteilhafterweise eine Abstützfläche auf, welche sich an einer inneren Deckelfläche des Führungselementes abstützt. Dadurch kann ein guter Lastabtrag über den Lagerbock auf die Lagerachse der Laufrolle erfolgen.The roller holder advantageously has a support surface, which is supported on an inner cover surface of the guide element. This allows a good load transfer via the bearing block on the bearing axis of the roller.
Des Weiteren ist bevorzugt vorgesehen, dass an dem Führungselement, insbesondere an dem Deckel des Führungselementes, ein Sicherungselement vorgesehen ist, das sich über die Querschnittsfläche des Führungsschachtes hinaus erstreckt. Vorteilhafterweises ist ein Wandabschnitt des Führungselementes mit einer Vertiefung versehen, so dass durch das über den Querschnitt des Führungselementes hinausragende Sicherungselemente eine Auf- und Abbewegung des Führungselementes in dem Führungsschacht zum Ein- und Ausfahren des Fahrwerkes ermöglicht ist. Sofern jedoch die mobile Hebebühne durch einen Lastkran oder ein anderes Hebemittel vollständig vom Boden abgehoben wird, beispielsweise zum Transport an einen anderen Standort, wird das Führungselement gegenüber einem vollständigen Herausfallen aus dem Führungsschacht gehindert. Das Sicherungselement liegt an einer Stirnkante der Seitenwand des Führungsschachtes an und verhindert ein Herausfallen.Furthermore, it is preferably provided that on the guide element, in particular on the cover of the guide element, a securing element is provided which extends beyond the cross-sectional area of the guide shaft addition. Advantageously, a wall section of the guide element is provided with a depression, so that an up and down movement of the guide element in the guide shaft for extending and retracting the chassis is made possible by the over the cross section of the guide element protruding securing elements. However, if the mobile lift is completely lifted off the ground by a loader crane or other lifting means, for example for transport to another location, the guide element is prevented from completely falling out of the guide shaft. The securing element bears against an end edge of the side wall of the guide shaft and prevents it from falling out.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass die Laufrollenverstelleinrichtung ein Gestänge aufweist, durch welches mit der Betätigungsvorrichtung eine Ausfahrbewegung der Laufrollen gegenüber dem Grundgestell ansteuerbar ist. Dadurch kann eine bereits bestehende Mechanik in der Betätigungseinrichtung für das Ein- und Ausfahren des Fahrwerks verwendet werden.A further preferred embodiment of the invention provides that the Laufrollenverstelleinrichtung has a linkage through which with the Actuator an extension movement of the rollers relative to the base frame is controlled. As a result, an existing mechanism in the actuator for extending and retracting the landing gear can be used.
Bevorzugt ist vorgesehen, dass das Gestänge einen vorzugsweise gabelförmigen Schwenkhebel aufweist, der auf das Führungselement wirkt und eine Ausfahrbewegung des Führungselementes nach unten gegenüber dem Führungsschacht ansteuert. Der Schwenkhebel liegt dabei bevorzugt lediglich auf dem Deckel des Führungselementes auf, so dass durch die schwenkbare Ansteuerung des Schwenkhebels bei einer zunehmenden Schwenkbewegung ein Angriffspunkt des Schwenkhebels entlang einer Oberfläche des Deckels gleitet, um die Ausfahrbewegung des Führungselementes anzusteuern. Ebenso kann an dem Schwenkhebel eine Stützrolle vorgesehen sein, welche auf dem Deckel während einer Ausfahrbewegung des Führungselementes gegenüber dem Führungsschacht abrollt.It is preferably provided that the linkage has a preferably fork-shaped pivot lever, which acts on the guide element and an extension movement of the guide element drives downward relative to the guide shaft. The pivot lever is preferably only on the cover of the guide element, so that slides by the pivotal actuation of the pivot lever with an increasing pivotal movement, a point of the pivot lever along a surface of the lid to control the extension movement of the guide element. Likewise, a support roller may be provided on the pivot lever, which rolls on the cover during an extension movement of the guide element relative to the guide shaft.
