Abstract
Description
Die Erfindung betrifft ein Anbaugerät für insbesondere verfahrbare Stapler.The invention relates to an attachment for in particular movable forklift.
Derartige, beispielsweise aus der EP 0 116 281 B1 oder dem DE 88 15 272 U1 bekannte Anbaugeräte besitzen Tragelemente, im allgemeinen paarweise zwei oder vier, häufig als Zinken ausgebildet, die Lasten ergreifen, anheben und absetzen können. Hierzu ist es erforderlich, daß die Tragelemente relativ zueinander verschoben werden können, um beispielsweise Paletten in unterschiedlichen Abmessungen ergreifen zu können.Such, for example from EP 0 116 281 B1 or the Attachments known from DE 88 15 272 U1 have support elements, generally two or four in pairs, often as tines trained to take, lift and set down the loads can. For this it is necessary that the support elements can be shifted relative to each other, for example Grab pallets in different dimensions to be able to.
Bewährt haben sich Anhaugeräte in Form eines Zinkenverstellgerätes mit Seitenschub und vier horizontal vorwärts gerichteten Lastzinken, die die Lasten aufnehmen, tragen und wieder absetzen. Die Zinken weisen an ihrem rückwärtigen Ende vertikale lotrechte Schenkel auf, so daß insgesamt L-förmige Tragarme gebildet werden. Diese L-förmigen Tragarme werden mit den lotrechten Schenkeln auf verschiedene Weise durch das Anbaugerät an einer Hubplatte eines Gabelstaplers angeordnet.Attachments in the form of a tine adjustment device have proven their worth with sideshift and four horizontally forward Load tines that carry, carry and stop again. The tines point to their rear End vertical vertical leg on, so that total L-shaped support arms are formed. These L-shaped arms with the vertical legs in different ways through the attachment on a lift plate of a forklift arranged.
Insbesondere bei Anbaugeräten mit vier oder mehr Tragelementen oder auch dann, wenn die Tragelemente weit über den seitlichen Bereich des Staplers hinaus bewegbar sein sollen, entstehen verschiedene Probleme. Eine solche Ausfahrbarkeit ist generell erwünscht, um beispielsweise ungünstig stehende Paletten noch aufgreifen zu können und sich auch in ungünstig gestalteten Gängen mit Winkeln noch mit einem Gabelstapler geeignet bewegen zu können. Especially for attachments with four or more support elements or even if the support elements far above the lateral area of the truck should be movable out various problems arise. Such extensibility is generally desired, for example, to be unfavorable Pallets can still be picked up and also unfavorable designed corridors with angles using a forklift to be able to move appropriately.
Die Probleme bestehen darin, daß die erforderlich werdenden Gestänge für den Fahrer des Gabelstaplers sichtbehindernd werden.The problems are that those that become necessary Linkage for the driver of the forklift to obstruct the view become.
Zur Vermeidung dieses Effekts ist in der EP 0 515 996 A1 ein Anbaugerät vorgeschlagen worden, das einen Hubrahmen mit zwei parallel verlaufenden Führungsachsen und diese verbindenden seitlichen Wangen aufweist. Auf den Führungsachsen sind Tragbalken verschiebbar gelagert. Diese verschiebbar gelagerten Tragbalken nehmen in zusätzlichen Bohrungen rohrförmige Träger auf, die an ihrem äußeren Ende mit einem Zinken oder Klemmelement verbunden sind. Das jeweils andere Ende der rohrförmigen Träger ist mit einem Anschlag ausgerüstet und berührungsfrei durch eine zusätzliche Ausnehmung in dem jeweiligen anderen Tragbalken durchschiebbar.To avoid this effect, EP 0 515 996 A1 an attachment has been proposed that includes a lifting frame with two parallel guide axes and these connecting side cheeks. On the management axes beams are slidably mounted. This slidable supported support beams take in additional holes tubular carrier, which at its outer end with a Tines or clamping element are connected. The other The end of the tubular support is equipped with a stop and contact-free thanks to an additional recess can be pushed through in the other supporting beam.
Diese Konstruktion hat sich sehr bewährt. Sie ist allerdings asymmetrisch. Dadurch kann bei dem Befördern von besonders schweren Lasten und bei vollständig ausgefahrenen Zinken das Problem unterschiedlicher Durchbiegung der jeweils äußersten Aufgreifzinken auftreten, da die Führungssysteme ungleiche Elastizität besitzen. Die jeweiligen rohrförmigen Träger sind nämlich in unterschiedlicher Lagerhöhe angeordnet, wodurch eine drehmomentbildende Kraft entsteht. Dies kann zu einer Querneigung und zu einem Ausfächern der Last führen, in Extremfällen auch zum Kippen. Um dies zu vermeiden, muß der Einsatzbereich derartiger Anbaugeräte entsprechend eingeschränkt werden.This construction has proven very successful. However, it is asymmetrical. This can be particularly useful when transporting heavy loads and with the tines fully extended the problem of different deflection of each extreme pick-up tines occur because of the guide systems have uneven elasticity. The respective tubular Beams are in fact arranged in different storage heights, which creates a torque-generating force. This can bank and fan out the load lead, in extreme cases also to tipping. To avoid this the area of application of such attachments must be appropriate be restricted.
Um dies zu vermeiden, wird in der EP 0 540 931 A1 eine andere Alternative vorgeschlagen. Anstelle der Tragbalken mit den durch diese hindurchgeführten Tragrohren und den daran fest angeschweißten Tragarmen wird eine Zwischentragplatte vorgesehen, die zwei Doppelachsen aufweist. Von den beiden Doppelachsen ist jeweils die obere durch den Hubrahmen und die untere durch das Tragelement beweglich geführt und gelagert. Auf diese Weise entsteht vollständige Symmetrie.To avoid this, EP 0 540 931 A1 describes a other alternative suggested. Instead of the supporting beams with the support tubes passed through them and the an intermediate support plate is welded onto the support arms provided that has two double axes. From the two double axes is the upper one through the Lift frame and the lower one movable through the support element managed and stored. This creates complete Symmetry.
Diese Konstruktion führt jedoch zu relativ vielen, nebeneinander parallel verlaufenden Achsen und so zu einer Einschränkung der Sichtmöglichkeiten des Gabelstaplerfahrers.However, this construction leads to a relatively large number, side by side parallel axes and so to a limitation the visibility of the forklift driver.
Aufgabe der Erfindung ist es, die Vorteile der EP 0 540 931 A1, nämlich die Symmetrie der Führungssysteme, mit einem geringeren Vorbaumaß zu verbinden.The object of the invention is to take advantage of EP 0 540 931 A1, namely the symmetry of the guidance systems, with one to connect smaller stem dimensions.
Diese Aufgabe wird durch ein Anbaugerät für insbesondere verfahrbare Stapler gelöst, mit einem Hubrahmen mit mindestens zwei parallel verlaufenden Führungsachsen und diese verbindenden Seitenwangen, mit mindestens zwei auf den Führungsachsen gelagerten und parallel zu diesen verschiebbaren Tragbalken, mit mindestens zwei Tragachsen für jeden Tragbalken, die parallel zu den Führungsachsen verlaufen, und mit Tragelementen, die verschiebbar auf den Tragachsen gelagert und insbesondere als Hub-, Klammer- oder Greifelemente ausgebildet oder mit solchen verbindbar sind.This task is accomplished by an attachment for in particular mobile forklift solved, with a lifting frame with at least two parallel guide axes and these connecting sidewalls, with at least two on the Guide axes mounted and movable parallel to these Support beam, with at least two support axes for each Support beams that run parallel to the guide axes and with support elements that are slidable on the support axes stored and especially as lifting, clamping or gripping elements trained or connectable to such.
Diese Konstruktion macht von einer Reihe von Merkmalen der EP 0 515 996 A1 Gebrauch, führt jedoch überraschend zu dem Vorteil vollständiger Symmetrie: Dadurch, daß die Tragelemente im Gegensatz zur EP 0 515 996 A1 nunmehr verschiebbar auf den Tragachsen gelagert sind, können zwei Alternativen für die Anordnung der Tragachsen selbst relativ zum (inneren) Tragbalken eingesetzt werden: Im Normalfall ist hier jetzt eine starre Verbindung möglich. Dies führt zu einer Umkehr gegenüber dem bisherigen Prinzip, denn jetzt sind nicht mehr die (äußeren) Tragelemente mitsamt den Tragachsen relativ zu den (inneren) Tragbalken verschiebbar wie bisher, sondern die (inneren) Tragbalken zusammen mit den Trachachsen relativ zu den (äußeren) Tragelementen. This construction makes of a number of features of the EP 0 515 996 A1 use, but surprisingly leads to the advantage of complete symmetry: the fact that the support elements in contrast to EP 0 515 996 A1 can now be moved are supported on the support axles, two alternatives for the arrangement of the support axes themselves relative to (inner) support beams are used: In the normal case A rigid connection is now possible here. this leads to a reversal of the previous principle, because now are no longer the (outer) supporting elements together with the Support axes can be moved relative to the (inner) support beams as before, but the (inner) beams together with the trach axes relative to the (outer) support elements.
Dadurch aber muß die gesamte Konstruktion nicht mehr über die Mittellinie der Hubrahmen hinausragen, beide Halbseiten können in der gleichen Ebene angeordnet werden, ohne sich gegenseitig zu stören. Dies reduziert sofort auch das Vorbaumaß, da eine komplette Bewegungsebene für die Achsen überflüssig wird und eingespart werden kann.As a result, however, the entire construction no longer has to protrude the center line of the lifting frame, both sides can be arranged on the same level without getting to interfere with each other. This also immediately reduces the stem dimensions, because a complete plane of movement for the axes is superfluous will and can be saved.
Durch die Anordnung aller Tragachsen in eine Ebene und darüber hinaus links und rechts in gleicher Höhe entsteht zudem die gewünschte Symmetrie. Das Ausfächern und Kippen von Lasten auf den Tragelementen bzw. den daran angeordneten Zinken entfällt vollständig.By arranging all axes in one plane and in addition left and right at the same height also the desired symmetry. Fanning out and tipping of loads on the support elements or arranged thereon Tines are completely eliminated.
Eine zweite Alternative der Erfindung zeichnet sich dadurch aus, daß die Tragachsen nicht starr mit den (inneren) Tragbalken verbunden sind, sondern vielmehr schwimmend in den (inneren) Tragbalken gelagert sind. Es sind jetzt also sowohl die Tragelemente, als auch die Tragbalken relativ zu den Tragachsen beweglich.A second alternative of the invention is characterized by this from that the support axles are not rigid with the (inner) support beams are connected, but rather floating in the (inner) support beams are stored. So now it is both the support elements and the support beams are relative movable to the supporting axes.
Dabei bietet die schwimmende Lagerung bevorzugt nur eine begrenzte Beweglichkeit. Der Vorteil dieser Maßnahme besteht darin, daß alle Vorteile der ersten Alternative benutzt werden können, darüber hinaus aber auch noch die Tragachsen bis zur Mittellinie des Hubrahmens eingefahren werden können, um beim Durchfahren von Engstellen die seitlichen Abmessungen auf ein Minimum zu reduzieren und so den Bewegungsspielraum der Gabelstapler mit Anbaugerät zu erhöhen. Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben. The floating bearing preferably only offers one limited mobility. The advantage of this measure is in that uses all the advantages of the first alternative can be, but also the supporting axes can be retracted up to the center line of the lifting frame, around the lateral dimensions when driving through narrow points reduced to a minimum and thus the freedom of movement raise the forklift with attachment. More beneficial Refinements are specified in the subclaims.
