Description

Die Erfindung betrifft ein Flurförderfahrzeug mit mindestens einer Kabine, welche mindestens eine nach oben gerichtete Säule aufweist. Diese mindestens eine Säule ist von Streben gebildet, von denen mindestens zwei längs und mindestens eine quer zur mindestens einen Säule verlaufen. Mindestens eine der Streben weist einander gegenüberliegende, keilförmige Schrägflächen auf. Diese Schrägflächen sind derart ausgerichtet, dass sich der Querschnitt der mindestens einen Strebe von Außenflächen der mindestens einen Säule nach innen vergrößert.The invention relates to an industrial truck with at least one cabin, which has at least one column pointing upwards. This at least one column is formed by struts, of which at least two run lengthways and at least one runs transversely to the at least one column. At least one of the struts has opposite, wedge-shaped inclined surfaces. These inclined surfaces are aligned in such a way that the cross section of the at least one strut increases from the inside of the at least one column.

Ein gattungsgemäßes Flurförderfahrzeug wird seitens der Firma Linde unter der Typbezeichnung E25 hergestellt. Dieses Flurförderfahrzeug bildet daher den nächstliegenden Stand der Technik.A generic industrial truck is manufactured by the Linde company under the type designation E25. This industrial truck therefore forms the closest prior art.

Der Erfindung liegt die Aufgabe zugrunde, ein Flurförderfahrzeug der eingangs genannten Art zu schaffen, an dem Anbauteile mit hoher Montagesicherheit anbringbar sind.The invention has for its object to provide an industrial truck of the type mentioned, to which attachments can be attached with high assembly reliability.

Diese Aufgabe wird erfindungsgemäß mit den folgenden Merkmalen gelöst.This object is achieved according to the invention with the following features.

Ein erfindungsgemäßes Flurförderfahrzeug weist mindestens eine Kabine auf. Diese Kabine weist mindestens eine nach oben gerichtete Säule auf, welche von Streben gebildet ist. Mindestens zwei der Streben verlaufen dabei längs zur mindestens einen Säule und mindestens eine der Streben verläuft quer zur mindestens einen Säule. Zwischen diesen Streben weist die mindestens eine Säule mindestens eine Durchbrechung und/oder Vertiefung auf. Durch diesen Aufbau ist die mindestens eine Säule sehr stabil, so dass sie hohen Kräften widerstehen kann. Mindestens eine der Streben weist keilförmige Schrägflächen auf, so dass sich der Querschnitt der mindestens einen Strebe von Außenflächen der mindestens einen Säule nach innen vergrößert. Um Anbauteile sicher am Flurförderfahrzeug anbauen zu können, sind Klemmplatten vorgesehen, die an mindestens einer der Schrägflächen der mindestens einen Strebe anliegen. Diese Klemmplatten überdecken die mindestens eine Durchbrechung und/oder Vertiefung mindestens teilweise. Die Klemmplatten sind jeweils passend zur jeweiligen Schrägfläche geformt und durch Haltemittel gegeneinander vorgespannt. Damit finden diese Klemmplatten einen festen Sitz an den Schrägflächen und können hohen Drehmomenten widerstehen. An mindestens einer dieser Klemmplatten ist mindestens ein Anbauteil abgestützt. Die Auswahl der Anbauteile ist grundsätzlich beliebig. Es ist hauptsächlich an Rückhaltesysteme, Außenspiegel, Beleuchtungskörper und Fahrerhilfssysteme gedacht. Diese Aufzählung ist jedoch nicht abschließend zu verstehen.An industrial truck according to the invention has at least one cabin. This cabin has at least one upward-facing column, which is formed by struts. At least two of the struts run longitudinally to the at least one column and at least one of the struts runs transversely to the at least one column. Between these struts, the at least one column has at least one opening and / or depression. This structure makes the at least one column very stable so that it can withstand high forces. At least one of the struts has wedge-shaped inclined surfaces, so that the cross section of the at least one strut increases inward from the outer surfaces of the at least one column. In order to be able to securely attach add-on parts to the industrial truck, clamping plates are provided which rest on at least one of the inclined surfaces of the at least one strut. These clamping plates at least partially cover the at least one opening and / or depression. The clamping plates are each shaped to match the respective inclined surface and are biased against each other by holding means. This means that these clamping plates are firmly seated on the inclined surfaces and can withstand high torques. At least one attachment is supported on at least one of these clamping plates. The choice of attachments is basically arbitrary. It is primarily intended for restraint systems, exterior mirrors, lighting fixtures and driver assistance systems. However, this list is not to be understood as exhaustive.

Zur Erzielung einer guten Klemmwirkung der Klemmplatten ist es günstig, wenn diese von den Außenflächen der mindestens einen Säule nach innen vorgespannt sind. Dadurch wandeln die Schrägflächen die Klemmplattenspannung in eine Kraft in der Klemmplattenebene um, so dass sich die Klemmplatten an den Schrägflächen regelrecht verkeilen. Dies führt zu einer sicheren Festlegung der Klemmplatten an der mindestens einen Säule.To achieve a good clamping effect of the clamping plates, it is advantageous if they are prestressed inwards by the outer surfaces of the at least one column. As a result, the inclined surfaces convert the clamping plate tension into a force in the clamping plate plane, so that the clamping plates literally wedge on the inclined surfaces. This leads to a secure fixing of the clamping plates on the at least one column.

Zur Verbesserung der Klemmwirkung der Klemmplatten ist es vorteilhaft, wenn die mindestens eine Strebe mindestens drei Schrägflächen aufweist, wobei die mindestens eine Klemmplatte an mindestens zwei der Schrägflächen der mindestens einen Strebe anliegt. Damit ist die mindestens eine Klemmplatte durch die Schrägflächen in zwei einander entgegengesetzten Richtungen fixiert und kann somit eine ausreichende Klemmwirkung erzielen, ohne an einer weiteren Strebe anzuliegen. Auf diese Weise ergibt sich ein besonders kompakter Aufbau der mindestens einen Klemmplatte.To improve the clamping effect of the clamping plates, it is advantageous if the at least one strut has at least three inclined surfaces, the at least one clamping plate abutting at least two of the inclined surfaces of the at least one strut. The at least one clamping plate is thus fixed in two opposite directions by the inclined surfaces and can thus achieve a sufficient clamping effect without being in contact with another strut. This results in a particularly compact construction of the at least one clamping plate.

Alternativ oder zusätzlich ist es vorteilhaft, wenn die mindestens eine Klemmplatte an mindestens zwei der Streben anliegt. Auf diese Weise wird ebenfalls eine ausreichend hohe Klemmwirkung der mindestens einen Klemmplatte erzielt. Allerdings muss die mindestens eine Klemmplatte in diesem Fall den freien Raum zwischen den Streben überbrücken, so dass sich insgesamt ein entsprechend vergrößerter Aufbau ergibt. Diese Maßnahme hat den Vorteil, dass die mindestens eine Klemmplatte einwirkende Drehmomente besser abstützen kann, was insbesondere bei Rückhaltesystemen zur Abstützung an der mindestens einen Klemmplatte von Vorteil ist.Alternatively or additionally, it is advantageous if the at least one clamping plate rests on at least two of the struts. In this way, a sufficiently high clamping effect of the at least one clamping plate is also achieved. In this case, however, the at least one clamping plate must bridge the free space between the struts, so that overall a correspondingly enlarged structure results. This measure has the advantage that the torques acting at least on one clamping plate can be better supported, which is particularly advantageous in the case of restraint systems for support on the at least one clamping plate.

Um möglichst hohe Drehmomente um eine vertikale Drehachse abstützen zu können, ist es vorteilhaft, wenn die mindestens eine Klemmplatte an mindestens zwei der längs zur mindestens einen Säule verlaufenden Streben anliegt.In order to be able to support the highest possible torques about a vertical axis of rotation, it is advantageous if the at least one clamping plate rests on at least two of the struts running longitudinally to the at least one column.

Müssen dagegen Drehmomente um eine horizontale Drehachse abgestützt werden, ist es günstiger, wenn die mindestens eine Klemmplatte an mindestens zwei der quer zur Säule verlaufenden Streben anliegt.If, on the other hand, torques have to be supported about a horizontal axis of rotation, it is more advantageous if the at least one clamping plate rests on at least two of the struts running transversely to the column.

Sind hohe Drehmomente in unterschiedlichen Richtungen abzustützen, was insbesondere bei Rückhaltesystemen der Fall ist, so ist es vorteilhaft, wenn die mindestens eine Klemmplatte an mindestens drei der Schrägflächen anliegt.If high torques are to be supported in different directions, which is particularly the case with restraint systems, it is advantageous if the at least one clamping plate rests on at least three of the inclined surfaces.

Als Haltemittel zur Verspannung der Klemmplatten zueinander hat sich mindestens eine Schraube bewährt. Auf diese Weise lassen sich mit relativ geringem Aufwand hohe Vorspannungen erzeugen. Außerdem sind derartige Verbindungen sehr sicher.At least one screw has proven itself as a holding means for clamping the clamping plates to one another. In this way, high preloads can be generated with relatively little effort. Such connections are also very secure.

Für das mindestens eine Anbauteil hat sich ein Rückhaltesystem für einen Fahrer des Flurförderfahrzeugs bewährt. Aufgrund der geometrischen Bedingungen, welche oben erklärt sind, lassen sich die damit auftretenden Drehmomente problemlos an der mindestens einen Säule abstützen.A restraint system for a driver of the industrial truck has proven itself for the at least one attachment part. Due to the geometric conditions, which are explained above, the resulting torques can be supported on the at least one column without any problems.

Da die mindestens eine Säule sehr biegefest ist, kann an dieser auch problemlos ein Hubzylinder angreifen, der einen Hubmasten des Flurförderfahrzeugs verstellt. Die dabei auftretenden Biegemomente kann die mindestens eine Säule problemlos abstützen.Since the at least one column is very resistant to bending, it can also be easily attacked by a lifting cylinder which adjusts a lifting mast of the industrial truck. The bending moments that occur can easily support the at least one column.

Der Erfindungsgegenstand wird beispielhaft anhand der Zeichnung erläutert, ohne den Schutzumfang zu beschränken.The subject matter of the invention is explained by way of example with reference to the drawing, without limiting the scope of protection.

Ein Flurförderfahrzeug 1 gemäß Figur 1 weist eine Karosserie 2 auf, die auf Rädern 3 abgestützt ist. An der Karosserie 2 ist ein Fahrersitz 4 für einen nicht dargestellten Fahrer abgestützt. Dieser Fahrersitz 4 ist von einer Kabine 5 umgeben, welche im Wesentlichen von heckseitig angeordneten Säulen 6 gebildet ist. An diesen Säulen 6 sind außerdem Hubzylinder 7 abgestützt, mit denen ein Hubmast 8 in seiner Winkellage verstellt werden kann. Dieser Hubmast 8 trägt eine Gabel 9 zur Aufnahme einer nicht dargestellten Ladung.An industrial truck 1 according to Figure 1 has a body 2, which is supported on wheels 3. A driver seat 4 for a driver, not shown, is supported on the body 2. This driver's seat 4 is surrounded by a cabin 5, which is essentially formed by columns 6 arranged at the rear. On these columns 6 lifting cylinders 7 are also supported, with which a lifting mast 8 can be adjusted in its angular position. This mast 8 carries a fork 9 for receiving a load, not shown.

Um zu verhindern, dass der Fahrer beispielsweise beim Umkippen des Flurförderfahrzeugs 1 verletzt wird, ist ein Anbauteil 12 in Form eines Rückhaltesystems 10 vorgesehen, welches einen Schutzbügel 11 aufweist. Dieser Schutzbügel 11 ist von der dargestellten Rückhaltestellung in eine nicht dargestellte Offenstellung verschwenkbar, in der der Fahrer einfach das Flurförderfahrzeug 1 betreten bzw. verlassen kann.In order to prevent the driver from being injured, for example, when the industrial truck 1 tips over, an attachment 12 in the form of a restraint system 10 is provided which has a protective bracket 11. This protective bracket 11 can be pivoted from the restraint position shown into an open position, not shown, in which the driver can simply enter or leave the industrial truck 1.

Beim Umkippen des Flurförderfahrzeugs 1 übt der Fahrer erhebliche Seitenkräfte auf das Rückhaltesystem 10 aus, die von diesem entsprechend abgestützt werden müssen. Aus diesem Grund ist eine drehmomentsichere Abstützung des Rückhaltesystems 10 erforderlich.When the industrial truck 1 tips over, the driver exerts considerable lateral forces on the restraint system 10, which must be supported accordingly by the latter. For this reason, a torque-proof support of the restraint system 10 is required.

Zur Bildung einer sicheren Abstützung des Rückhaltesystems 10 sind die Säulen 6 von mehreren Streben 13 gebildet. Zwei dieser Streben 13 verlaufen dabei nach oben längs zur Säule 6, während zwischen diesen quer laufende Streben 13 vorgesehen sind. Diese Anordnung von Streben 13 ergibt einen sehr verwindungssteifen Aufbau, der eine optimale Festlegung des Rückhaltesystems 10 gewährleistet. Die Streben 13 weisen dabei Schrägflächen 14 auf, die von den beiden Außenflächen der Säule 6 zur Säulenmitte hin eine Querschnittsvergrößerung der Strebe 13 ergeben. Ein Freiraum 15 zwischen den Streben 13 verjüngt sich daher von den Außenflächen der Säulen 6 zu den Säulenmitten hin.In order to form a secure support for the restraint system 10, the columns 6 are formed by a plurality of struts 13. Two of these struts 13 run upwards along the column 6, while transverse struts 13 are provided between them. This arrangement of struts 13 results in a very torsionally rigid structure, which ensures an optimal fixing of the restraint system 10. The struts 13 have inclined surfaces 14 which from the two outer surfaces of the column 6 to Column center towards an increase in cross section of the strut 13. A free space 15 between the struts 13 therefore tapers from the outer surfaces of the columns 6 to the center of the column.

An den Schrägflächen 14 sind Klemmplatten 16 gehalten, welche zu den Schrägflächen 14 passend geformt sind. Diese Klemmplatten 16 sind mittels Haltemittel 17 in Form von Schrauben gegeneinander vorgespannt. Auf diese Weise pressen sich die Flächen der Klemmplatten 16 an die Schrägflächen 14 und ergeben einen festen, drehmomentsicheren Halt für das Anbauteil 12.Clamping plates 16 are held on the inclined surfaces 14, which are shaped to match the inclined surfaces 14. These clamping plates 16 are biased against one another by means of holding means 17 in the form of screws. In this way, the surfaces of the clamping plates 16 press against the inclined surfaces 14 and result in a firm, torque-proof hold for the attachment 12.

Aus Figur 2 ist zu ersehen, dass die Klemmplatten 16 nur an den Schrägflächen jener Streben 13 anliegen, die längs zur Säule 6 verlaufen. Damit ergibt sich ein einfacher Aufbau, der für Drehmomente in vertikaler Drehrichtung in der Regel ausreichend ist. Da dies die Hauptmomente sind, die das Rückhaltesystem 10 abstützen muss, ist diese Ausführungsform bevorzugt anzuwenden.Out Figure 2 it can be seen that the clamping plates 16 rest only on the inclined surfaces of those struts 13 which run longitudinally to the column 6. This results in a simple structure, which is generally sufficient for torques in the vertical direction of rotation. Since these are the main moments that the restraint system 10 must support, this embodiment is preferred to be used.

Die Figur 3 zeigt eine alternative Ausführungsform, wobei gleiche Bezugszeichen gleiche Teile benennen. Im Folgenden wird nur auf die Unterschiede zur Figur 2 eingegangen.The Figure 3 shows an alternative embodiment, wherein the same reference numerals designate the same parts. The following is only the differences Figure 2 received.

Bei der Ausführungsform gemäß Figur 3 erfassen die Klemmplatten 16 den gesamten Freiraum 15 zwischen den Streben 13. Damit liegen die Klemmplatten 16 an allen Rändern 18 an den entsprechenden Schrägflächen 14 der Streben 13 an. Auf diese Weise ergibt sich eine optimale Klemmung der Klemmplatten 16, um größte Drehmomente in unterschiedlichen Drehrichtungen abzustützen. Nachteilig ist allerdings, dass die Klemmplatten 16 sehr genau an die Form der Streben 13 ängepasst werden müssen.In the embodiment according to Figure 3 the clamping plates 16 capture the entire free space 15 between the struts 13. The clamping plates 16 thus rest on all edges 18 on the corresponding inclined surfaces 14 of the struts 13. In this way, the clamping plates 16 are optimally clamped in order to support the greatest torques in different directions of rotation. However, it is disadvantageous that the clamping plates 16 have to be adapted very precisely to the shape of the struts 13.

Die Figur 4 zeigt eine weitere Ausführungsform, wobei gleiche Bezugszeichen wieder gleiche Teile benennen. Im Folgenden wird lediglich auf die Unterschiede zur Figur 2 eingegangen.The Figure 4 shows a further embodiment, the same reference numerals again designating the same parts. The following is only the differences Figure 2 received.

Bei der Ausführungsform gemäß Figur 4 erfassen die Klemmplatten 16 die Schrägflächen 14 jeweils einer der quer verlaufenden Streben 13. Damit können die Klemmplatten 16 besonders klein ausgebildet werden. Folglich ergibt sich ein besonders einfacher Aufbau, allerdings auf Kosten der Momentenabstützung in vertikaler Drehrichtung. In einfachen Anwendungsfällen ist dies jedoch ausreichend.In the embodiment according to Figure 4 the clamping plates 16 grip the inclined surfaces 14 in each case one of the transverse struts 13. The clamping plates 16 can thus be made particularly small. This results in a particularly simple construction, but at the expense of torque support in the vertical direction of rotation. In simple applications, however, this is sufficient.

Es ist insbesondere auch daran gedacht, die Klemmplatten 16 in Kombination der Ausführungsbeispiele gemäß den Figuren 2 und 4 auszubilden. Dabei erfassen die Klemmplatten 16 die Schrägflächen 14 benachbarter, quer verlaufender Streben 13, so dass sie sich über den Freiraum 15 in annähernd vertikaler Richtung erstrecken. Auf diese Weise ergibt sich eine besonders vorteilhafte Abstützung von Drehmomenten um eine horizontale Drehachse.It is in particular also contemplated that the clamping plates 16 in combination of the embodiments according to the Figures 2 and 4 train. The clamping plates 16 grip the inclined surfaces 14 of adjacent, transverse struts 13, so that they extend over the free space 15 in an approximately vertical direction. This results in a particularly advantageous support of torques about a horizontal axis of rotation.

Darüber hinaus sind weitere Kombinationen der gezeigten Ausführungsbeispiele denkbar.In addition, further combinations of the exemplary embodiments shown are conceivable.
