Description

Die Erfindung betrifft ein Hubwerk für ein Flurförderzeug, insbesondere für ein Hochregalflurförderzeug, mit zwei in Querrichtung des Flurförderzeugs beabstandeten Standmasten.The invention relates to a hoist for an industrial truck, in particular for a High-bay industrial truck, with two spaced apart in the transverse direction of the industrial truck Stand masts.

Die Standmasten des Hubwerks sind bei Hochregalflurförderzeugen starr mit dem Rahmen des Hochregalflurförderzeugs verbunden und im Wesentlichen senkrecht ausgerichtet. Bei anderen Flurförderzeugen, wie beispielsweise Gegengewichtsgabelstaplern, sind die Standmasten häufig neigbar an dem Rahmen befestigt. Üblicherweise ist jedem Standmast mindestens ein Ausfahrmast zugeordnet, der an dem Standmast in vertikaler Richtung verschiebbar geführt ist.The masts of the hoist are rigid with the high-bay industrial trucks Frame of the high-bay truck connected and essentially vertical aligned. With other industrial trucks, such as Counterbalance forklifts, the masts are often tiltable on the frame attached. Usually at least one extension mast is assigned to each standing mast, which is slidably guided on the mast in the vertical direction.

Standmasten des Standes der Technik bestehen in der Regel aus einem einzigen durchgehenden Stahlprofil. Der Querschnitt dieses Stahlprofils ist derart ausgelegt, dass es ausreichende Trägheitsmomente in Längsrichtung und in Querrichtung des Flurförderzeugs aufweist. Gleichzeitig ist das Stahlprofil derart geformt, dass es mindestens eine Lauffläche für eine Führungsrolle des Ausfahrmasts aufweist. Dies bedingt eine komplizierte Formgebung und damit eine aufwändige Herstellung der Stahlprofile. Üblicherweise ist das verwendete Stahlprofil für die Hubwerke jeder Tragkraftklasse speziell ausgelegt. Dies bedeutet, dass für unterschiedliche Hubwerke auch unterschiedliche Profile verwendet werden, die sich hinsichtlich ihrer Stärke und damit ihrer Trägheitsmomente unterscheiden.Stand masts of the prior art generally consist of a single one continuous steel profile. The cross section of this steel profile is designed that there are sufficient moments of inertia in the longitudinal and transverse directions of the Has industrial truck. At the same time, the steel profile is shaped in such a way that it has at least one running surface for a guide roller of the extension mast. This requires a complicated shape and thus a complex production of the Steel profiles. Usually the steel profile used for the hoists is everyone Capacity class specially designed. This means that for different hoists also different profiles are used, which differ in terms of their strength and thus distinguish their moments of inertia.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, die Konstruktion eines Hubwerks zur Verfügung zu stellen, bei der für unterschiedliche Tragkraftklassen gleiche Stahlprofile verwendet werden können.The present invention is based on the object, the construction of a To provide hoist for different load capacity classes same steel profiles can be used.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass jeder Standmast von einem Stahlprofil und mindestens einem sich längs des Stahlprofils erstreckenden, an das Stahlprofil angeschweißten Blech gebildet ist. Sowohl das Stahlprofil, als auch das Blech tragen zu der Steifigkeit des Standmasts bei. Die Laufflächen für die Führungsrollen sind ausschließlich von den Stahlprofilen gebildet. Die Kombination von Stahlprofil und Blech erlaubt eine einfache und leichte Ausführung des Stahlprofils, da auch das Blech zur Steifigkeit der Anordnung beiträgt.This object is achieved in that each standing mast of a steel profile and at least one extending along the steel profile the steel profile welded sheet is formed. Both the steel profile and that Sheet metal contributes to the rigidity of the mast. The treads for the Guide rollers are formed exclusively from the steel profiles. The combination of Steel profile and sheet metal allow a simple and easy execution of the steel profile, because the sheet also contributes to the rigidity of the arrangement.

Mindestens ein Blech weist eine zumindest annähernd ebene Fläche auf, die im Wesentlichen senkrecht zu der Querrichtung des Flurförderzeugs ausgerichtet ist. Die ebene Fläche ist damit vertikal ausgerichtet und ist parallel zu der Längsrichtung des Flurförderzeugs. Damit trägt das Blech insbesondere zur Erhöhung der Steifigkeit des Standmastes in Längsrichtung des Flurförderzeugs bei.At least one sheet has an at least approximately flat surface, which in the Is oriented substantially perpendicular to the transverse direction of the industrial truck. The flat surface is thus aligned vertically and is parallel to the longitudinal direction of the Industrial truck. The sheet thus contributes in particular to increasing the rigidity of the Stand mast in the longitudinal direction of the truck.

Mit besonderem Vorteil weist mindestens ein Blech im Bereich der ebenen Fläche mindestens einen Ausschnitt auf. Durch das gezielte Anbringen von Ausschnitten kann das Verhältnis von Gewicht und Steifigkeit des Blechs und damit des Standmasts optimiert werden. Darüber hinaus ermöglichen die Ausschnitte eine Durchsicht durch den Standmast in Querrichtung des Flurförderzeugs.It is particularly advantageous if at least one sheet has in the area of the flat surface at least a section. By making targeted cutouts the ratio of the weight and stiffness of the sheet and therefore the mast be optimized. In addition, the cutouts allow a look through the mast in the transverse direction of the truck.

Der Ausschnitt ist - in Längsrichtung des Flurförderzeugs betrachtet - an der dem Stahlprofil abgewandten Seite der ebenen Fläche angeordnet. Im Bereich der Schweißverbindung mit dem Stahlprofil ist das Blech damit von oben bis unten durchgehend. An die dem Stahlprofil abgewandte Seite der Ausschnitte schließt sich wieder ein von oben bis unten durchgehender Abschnitt des Blechs an. Dieser durchgehende Abschnitt kann gegenüber der ebenen Fläche um 90 Grad abgewinkelt sein.The section is - viewed in the longitudinal direction of the truck - on the Steel profile facing away from the flat surface. In the field of The sheet is therefore welded to the steel profile from top to bottom continuous. The side of the cutouts facing away from the steel profile closes again a section of the sheet from top to bottom. This continuous section can be angled 90 degrees from the flat surface his.

Die dem Stahlprofil zugewandte Seite des Ausschnitts weist eine gebogene, vorzugsweise eine teilelliptische Form auf. Damit wird die Entstehung von Spannungsspitzen an den Kanten der Ausschnitte verhindert.The side of the cutout facing the steel profile has a curved, preferably a partially elliptical shape. This will create Stress peaks on the edges of the cutouts prevented.

Vorzugsweise weist mindestens eine Blech mehrere gleichartige, in senkrechter Richtung voneinander beabstandete Ausschnitte auf.At least one sheet preferably has several of the same kind, in a vertical direction Cutouts spaced from each other.

Weiter ist es vorteilhaft, wenn mindestens ein Blech derart abgewinkelt ist, dass es einen flächigen Abschnitt aufweist, der im Wesentlichen senkrecht zu der Längsachse des Flurförderzeugs ausgerichtet ist. Die Steifigkeit des Standmasts kann durch die Abmessungen des abgewinkelten flächigen Abschnitts eingestellt werden. It is also advantageous if at least one sheet is angled such that it is has a flat section which is substantially perpendicular to the longitudinal axis the truck is aligned. The rigidity of the mast can be increased by the Dimensions of the angled flat section can be set.

Figur 1 zeigt ein erfindungsgemäßes Hubwerk eines Hochregalflurförderzeugs in perspektivischer Ansicht. Das Hubwerk weist zwei Standmasten 1, 2 auf, an denen die Ausfahrmasten 3 mittels nicht dargestellter Führungsrollen in vertikaler Richtung bewegbar geführt sind. An den Ausfahrmasten 3 wiederum ist ein Hubschlitten 4 vertikal verschiebbar geführt, der eine Befestigungsplatte 5 zur Befestigung eines Lastaufnahmemittels, beispielsweise einer Schwenkschubgabel, aufweist. Zwischen der Befestigungsplatte 5 und den Ausfahrmasten 3 ist ein Fahrkorb für eine Bedienperson befestigbar, der ebenfalls mit dem Hubschlitten 4 angehoben wird. Der Antrieb der Hubbewegung der Ausfahrmasten 3 und des Hubschlittens 4 erfolgt mittels hydraulischer Hubzylinder 6.Figure 1 shows an inventive hoist of a high-bay industrial truck in perspective view. The hoist has two masts 1, 2, on which the Extension masts 3 by means of guide rollers, not shown, in the vertical direction are movably guided. A lifting carriage 4 is in turn located on the extension masts 3 guided vertically displaceably, a mounting plate 5 for mounting a Load suspension means, for example a swivel push fork. Between the mounting plate 5 and the extending masts 3 is a car for one Operator can be attached, which is also raised with the lifting carriage 4. The The lifting movement of the extending masts 3 and the lifting carriage 4 is driven by means of hydraulic lifting cylinder 6.

In Figur 2 sind die Standmasten 1, 2 im Detail dargestellt. Jeder Standmast 1, 2 besteht aus einem Stahlprofil 7, 8 und daran angeschweißten Blechen 9, 10. Im unteren Bereich der Standmasten 1, 2, in dem keine Bleche befestigt sind, befinden sich Befestigungselemente 12 zur Anbindung des Hubwerks an einen Rahmen des Hochregalflurförderzeugs. Die Bleche 9, 10 weisen jeweils eine ebene Fläche auf, die senkrecht zu der Querrichtung des Hubwerks und damit des Flurförderzeugs ausgerichtet ist. In diesen ebenen Flächen sind Ausschnitte 11 vorgesehen, die die Durchsicht in Querrichtung des Flurförderzeugs erlauben, aber auch eine Durchführung von Leitungen und einen Zugriff auf die innen liegenden Teile des Hubwerks ermöglichen. Abgewinkelte flächige Abschnitte 13 der Bleche 9, 10 erhöhen die Steifigkeit der Standmasten 1, 2.In Figure 2, the masts 1, 2 are shown in detail. Each mast 1, 2 consists of a steel profile 7, 8 and welded sheets 9, 10. Im lower area of the masts 1, 2, in which no sheets are attached itself fasteners 12 for connecting the hoist to a frame of the High-bay industrial truck. The sheets 9, 10 each have a flat surface, the perpendicular to the transverse direction of the hoist and thus the truck is aligned. In these flat surfaces cutouts 11 are provided, which Allow viewing in the transverse direction of the truck, but also one Implementation of lines and access to the internal parts of the Enable hoist. Raise angled flat sections 13 of the sheets 9, 10 the rigidity of the masts 1, 2.

Sowohl die Stahlprofile 7, 8, als auch die Bleche 9, 10 liefern einen Beitrag zur Steifigkeit des Hubwerks. Aufgrund der Ausrichtung der ebenen Flächen erhöhen die Bleche 9, 10 insbesondere das Trägheitsmoment der Standmasten um die Querachse des Hubwerks. Eine Anpassung dieses Trägheitsmoments der Standmasten kann bei unverändertem Stahlprofil 7, 8 durch Variation der Stärke und/oder der Breite der Bleche 9, 10 erfolgen. Die Höhe der Hubwerks kann in einfacher Weise durch Auswahl eines längeren Stahlprofils 7,8 in Kombination mit zusätzlichen oder längeren Blechen 9, 10 variiert werden.Both the steel profiles 7, 8 and the sheets 9, 10 make a contribution to Rigidity of the hoist. Due to the orientation of the flat surfaces, the Sheets 9, 10 in particular the moment of inertia of the masts about the transverse axis of the hoist. An adjustment of this moment of inertia of the masts can unchanged steel profile 7, 8 by varying the thickness and / or the width of the Sheets 9, 10 take place. The height of the hoist can be easily selected a longer steel profile 7.8 in combination with additional or longer sheets 9, 10 can be varied.
