Description

FLURFÖRDERZEUG MIT ANHÄNGEVORRICHTUNG TRUCKS WITH TRAILER
Die Erfindung betrifft ein Flurforderzeug gemäß Oberbegriff des Anspruchs 1.The invention relates to a floor tool according to the preamble of claim 1.
Flurforderzeuge der hier angesprochenen Art sind bekannt (DE 87 15 730 Ul) . Sie dienen üblicherweise zum Transport von mit Stuckgut beladenen Paletten und weisen hierzu einen hohenverstellbaren Gabeltrager mit mehreren Gabelarmen zur Aufnahme einer Palette auf. Um das Flurforderzeug auch als Zug- oder Rangierfahrzeug für Anhanger nutzen zu können, kann es mit einer Anhangevorrichtung versehen werden, die auf einer palettenahlichen Plattform montiert ist. Das Anbringen der als separates Bauteil ausgeführten Plattform am Flurforderzeug erfolgt derart, dass die Plattform von den Gabelarmen untergriffen und aufgenommen wird. Nachfolgend wird die Plattform am Gabeltrager verliersicher befestigt. Wenn die Anhangevorrichtung nicht mehr benotigt wird, muss die Plattform vom Flurforderzeug entfernt werden. Nachteilig ist das unkomfortable Anbringen und Abbauen der Plattform am beziehungsweise vom Flurforderzeug sowie die vom Flurforderzeug getrennte Aufbewahrung der Plattform.Floor tools of the type mentioned here are known (DE 87 15 730 Ul). They are usually used to transport pallets loaded with piece goods and for this purpose have a highly adjustable fork carriage with several fork arms for receiving a pallet. In order to be able to use the ground tool as a towing or shunting vehicle for trailers, it can be equipped with an attachment device that is mounted on a platform close to the pallet. The platform, which is designed as a separate component, is attached to the floor tool in such a way that the platform is gripped and received by the fork arms. The platform is then captively secured to the fork carriage. If the trailer device is no longer required, the platform must be removed from the floor tool. Disadvantages are the uncomfortable attachment and detachment of the platform to or from the floor tool and the storage of the platform separate from the floor tool.
Es ist Aufgabe der Erfindung, ein Flurforderzeug der eingangs genannten Art zu schaffen, das vorzugsweise einen einfachen Aufbau aufweist und ohne aufwendige Umrust- /Umbaumaßnahmen sowohl zum Transport von Paletten und Stuckgut als auch als Zug- oder Rangierfahrzeug für Anhanger einsetzbar ist.It is an object of the invention to provide a floor product of the type mentioned, which preferably has a simple structure and without expensive retrofitting / conversion measures for both the transport of pallets and Stuckgut as well as a towing or shunting vehicle for trailers can be used.
Zur Losung der Aufgabe wird ein Flurforderzeug mit den Merkmalen des Anspruchs 1 vorgeschlagen. Dieses zeichnet sich dadurch aus, dass die Plattform schwenkbeweglich am Gabeltrager gelagert und in eine Gebrauchsstellung und in eine Nichtgebrauchsstellung schwenkbar ist. Bei in Nichtgebrauchsstellung angeordneter Plattform ist das Flurforderzeug zum Transport von Paletten mittels des Gabeltragers und bei in Gebrauchsstellung angeordneter Plattform zum Transport von Stuckgut und als Zug- oder Rangierfahrzeug für Anhanger einsetzbar. Die Plattform ist also fester Bestandteil des Flurforderzeugs und nicht ein separates Zubehörteil, wie bei dem bekannten Flurforderzeug.To solve the problem, a floor tool with the features of claim 1 is proposed. This is characterized by the fact that the platform is pivotally mounted on the fork carriage and can be pivoted into a use position and a non-use position. When the platform is arranged in the non-use position, the ground vehicle can be used for transporting pallets by means of the fork carriage and when the platform is arranged in the use position for the transport of stucco and as a towing or shunting vehicle for trailers. The platform is therefore an integral part of the floor tool and not a separate accessory, as in the known floor tool.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass die Schwenkachse der Plattform vorzugsweise quer zur Fahrrichtung des Flurforderzeugs verlauft. Darüber hinaus ist die Plattformschwenkachse vorzugsweise unmittelbar benachbart zu einem Hubgerust, an dem der Gabeltrager verfahrbar angebracht ist, angeordnet. Dadurch wird erreicht, dass die in Nichtgebrauchsstellung verschwenkte Plattform nicht beim Palettentransport stört. Die Plattform ist vorzugsweise am Gabeltrager schwenkbar gelagert, wird also gemeinsam mit diesem hohenverstellt , unabhängig davon, ob sie in Gebrauchsstellung heruntergeklappt oder in Nichtgebrauchsstellung hochgeklappt ist.According to a development of the invention, it is provided that the pivot axis of the platform preferably runs transversely to the direction of travel of the ground vehicle. In addition, the platform pivot axis is preferably arranged immediately adjacent to a lifting frame on which the fork carriage is movably attached. This ensures that the platform pivoted into the non-use position does not interfere with the pallet transport. The platform is preferably pivotally mounted on the fork carriage, so it is adjusted together with it, regardless of whether it is folded down in the use position or folded up in the non-use position.
Bevorzugt wird auch ein Ausfuhrungsbeispiel des Flurforderzeugs, bei dem die Plattform in der Nichtgebrauchsstellung senkrecht oder im Wesentlichen senkrecht zu Gabelarmen des Gabeltragers steht. Sofern die Plattform in der Nichtgebrauchsstellung im Blickfeld eines Bedieners/Fahrers des Flurforderzeugs angeordnet ist, kann es vorteilhaft sein, die Plattform zumindest an den geeigneten Stellen durchsichtig auszufuhren oder mit wenigstens einer entsprechenden Durchblickoffnung zu versehen. Bei dieser Anordnung kann die Plattform gleichzeitig auch als Schutz des Bedieners/Fahrers des Flurforderzeugs vor vom Gabeltrager unbeabsichtigt herabfallenden Teilen dienen, so dass auf zusatzliche Einrichtungen zu diesem Zweck gegebenenfalls verzichtet werden kann.Also preferred is an exemplary embodiment of the floor tool, in which the platform is perpendicular or substantially perpendicular to the fork arms of the fork carrier in the non-use position. If the platform is arranged in the non-use position in the field of vision of an operator / driver of the ground vehicle, it can be advantageous to make the platform transparent, at least at the appropriate points, or at least with it to provide a corresponding perspective opening. With this arrangement, the platform can at the same time also serve as protection for the operator / driver of the ground vehicle against parts falling unintentionally from the fork carriage, so that additional devices for this purpose can be dispensed with if necessary.
Weiterhin wird ein Ausfuhrungsbeispiel des Flurforderzeugs bevorzugt, das sich dadurch auszeichnet, dass die Plattform in der Gebrauchsstellung von den Gabelarmen abgestutzt ist. Die Plattform liegt also auf den Gabelarmen auf und ist vorzugsweise derart gelagert, dass sie gemeinsam mit den Gabelarmen in der Hohe, also in senkrechter Richtung verfahrbar sind, so dass in einfacher Weise eine Hohenausrichtung der Anhangevorrichtung gegenüber einer Deichsel oder ahnlichem des zu bewegenden Anhangers ohne zusatzliche Einrichtungen möglich ist.Furthermore, an exemplary embodiment of the floor tool is preferred, which is characterized in that the platform is supported by the fork arms in the use position. The platform therefore rests on the fork arms and is preferably mounted in such a way that they can be moved together with the fork arms in the height, that is to say in the vertical direction, so that in a simple manner a height orientation of the attachment device relative to a drawbar or the like of the trailer to be moved without additional facilities is possible.
Bei einer vorteilhaften Ausfuhrungsvariante des Flurforderzeugs überdeckt die Abstellflache einen Freiraum zwischen den mindestens zwei, parallel zueinander verlaufenden sowie in einem Abstand voneinander angeordneten Gabelarmen. Die Abstellflache ist somit besonders groß, so dass entsprechend großes Stuckgut und/oder viele unpalletierte Stuckguter transportierbar sind.In an advantageous embodiment variant of the floor tool, the storage area covers a free space between the at least two fork arms running parallel to one another and spaced apart from one another. The storage space is therefore particularly large, so that appropriately large pieces of goods and / or many unpalleted pieces of stucco can be transported.
Nach einer Weiterbildung der Erfindung ist eine der Plattform zugeordnete Querkraftabstutzungseinπchtung vorgesehen, die bei in Gebrauchsstellung herabgelassener Plattform ein Verrutschen derselben auf den Gabelarmen vorzugsweise verhindert, zumindest aber auf ein unschädliches Maß reduziert. Bei einer vorteilhaften Ausfuhrungsform ist die Querkraftabstutzungseinrichtung von einer auf der Unterseite, als der den Gabelarmen zugewandten Flachseite der Plattform angeordneten Querleiste gebildet, die in den Freiraum zwischen die Gabelarme eingreift und als Anschlag in Querrichtung dient. Um zu verhindern, dass die Plattform unbeabsichtigt aus der Nichtgebrauchsstellung in die Gebrauchsstellung herunterfallt, kann das Flurforderzeug mit einer Arretierungsvorrichtung zum Arretieren der Plattform in der Nichtgebrauchsstellung versehen sein.According to a development of the invention, a transverse force support device assigned to the platform is provided which, when the platform is lowered in the position of use, preferably prevents it from slipping on the fork arms, but at least reduces it to a harmless level. In an advantageous embodiment, the transverse force support device is formed by a transverse bar arranged on the underside, as the flat side of the platform facing the fork arms, which engages in the space between the fork arms and serves as a stop in the transverse direction. In order to prevent the platform from unintentionally falling from the non-use position into the use position, the floor tool can be provided with a locking device for locking the platform in the non-use position.
Die Plattform ist entweder manuell oder automatisch mittels einer geeigneten Stelleinrichtung zwischen der Gebrauchs- und der Nichtgebrauchsstellung schwenkbar. Vorzugsweise ist auch die Arretierung der Plattform in der Nichtgebrauchsstellung und gegebenenfalls in der Gebrauchsstellung automatisiert möglich.The platform can be swiveled either manually or automatically by means of a suitable adjusting device between the use and the non-use position. The locking of the platform in the non-use position and, if appropriate, in the use position is preferably also possible in an automated manner.
Im Zusammenhang mit der hier- vorliegenden Erfindung wird unter dem Begriff "Flurforderzeug" ein Gabelhubwagen, insbesondere Gabelniederhubwagen oder Gabelhochhubwagen, ein Gabelstapler sowie samtliche andere von Hand bewegbare o- der motorisch angetriebene Fahrzeuge, die Gabelarme zum Transport von Paletten aufweisen, verstanden.In connection with the present invention, the term “floor truck” is understood to mean a pallet truck, in particular a pallet truck or a pallet truck, a forklift and all other manually movable or motor-driven vehicles which have fork arms for transporting pallets.
Weitere vorteilhafte Ausfuhrungsbeispiele des Flurforderzeugs ergeben sich aus Kombinationen der in den Unteran- spruchen genannten Merkmale.Further advantageous exemplary embodiments of the field product result from combinations of the features mentioned in the subclaims.
Die Erfindung wird im Folgenden anhand der Zeichnung naher erläutert. Es zeigen:The invention is explained in more detail below with reference to the drawing. Show it:

Fig. 9 ein Ausfuhrungsbeispiel einer mit einer Anhangevorrichtung versehenen Plattform in perspektivischer Darstellung. Figur 1 zeigt eine Seitenansicht und Figur 2 eine Draufsicht auf ein Ausfuhrungsbeispiel eines Flurforderzeugs 1, das hier von einem Gabelniederhubwagen gebildet ist. Das Flurforderzeug 1 umfasst einen Gabeltrager 3 mit zwei in einem Abstand voneinander angeordneten, parallel zueinander verlaufenden Gabelarmen 5 und 7. Diese werden insbesondere im Zusammenhang mit Gabelstaplern auch als Gabelzinken bezeichnet. Der Gabeltrager 3 ist an einem nicht naher dargestellten Hubgerust 9 senkrecht zu einer gedachten Horizontalen verfahrbar, wie mit einem Doppelfeil 11 angedeutet. Der Aufbau und die Funktion des Flurforderzeugs 1 , insbesondere hinsichtlich der Hubvorrichtung zum Anheben beziehungsweise Absenken des Gabeltragers 3, ist grundsatzlich bekannt, so dass hier nicht naher darauf eingegangen wird.Fig. 9 shows an exemplary embodiment of a platform provided with an attachment device in a perspective view. FIG. 1 shows a side view and FIG. 2 shows a top view of an exemplary embodiment of a floor tool 1, which is formed here by a low-lift truck. The floor vehicle 1 comprises a fork carriage 3 with two fork arms 5 and 7 arranged at a distance from one another and running parallel to one another. These are also referred to as fork tines, in particular in connection with forklifts. The fork carriage 3 can be moved on a lifting frame 9, not shown in more detail, perpendicular to an imaginary horizontal, as indicated by a double file 11. The structure and function of the floor tool 1, in particular with regard to the lifting device for lifting or lowering the fork carriage 3, is known in principle, so that it will not be discussed in more detail here.
Am Gabeltrager 3 ist eine Plattform 13 angeordnet, die um eine senkrecht zur Bildebene der Figur 1, also quer zur Fahrrichtung des Flurforderzeugs 1 verlaufende Achse 15 schwenkbar ist. Die Plattform 13 ist in den Figuren 1 und 2 in eine Nichtgebrauchsstellung nach oben geklappt, in der sie senkrecht zur Horizontalen steht. Bei in Nichtgebrauchsstellung angeordneter Plattform 13 ist das Flurforderzeug 1 zum Transport von Paletten einsetzbar. In den Figuren 1 und 2 ist eine Gitterpalette 17 dargestellt, die von den Gabelarmen 5, 7 des Gabeltragers 3 aufgenommen ist .A platform 13 is arranged on the fork carriage 3 and can be pivoted about an axis 15 running perpendicular to the image plane of FIG. 1, that is to say transversely to the direction of travel of the ground vehicle 1. In FIGS. 1 and 2, the platform 13 is folded up into a non-use position in which it is perpendicular to the horizontal. When the platform 13 is arranged in the non-use position, the floor tool 1 can be used to transport pallets. In Figures 1 and 2, a grid pallet 17 is shown, which is received by the fork arms 5, 7 of the fork carriage 3.
Figur 3 zeigt eine Seitenansicht und Figur 4 eine Draufsicht des Flurforderzeugs 1 mit teilweiser heruntergeklappter Plattform 13. Die in den Figuren 3 und 4 dargestellte Stellung der Plattform 13 ist eine Zwischenstellung beim Verschwenken derselben aus der Nichtgebrauchsstellung in eine Gebrauchsstellung.FIG. 3 shows a side view and FIG. 4 shows a plan view of the ground tool 1 with the platform 13 partially folded down. The position of the platform 13 shown in FIGS. 3 and 4 is an intermediate position when the latter is pivoted out of the non-use position into a use position.
Figur 5 zeigt eine Seitenansicht und Figur 6 eine Draufsicht auf das Flurforderzeug 1 mit in Gebrauchsstellung angeordneter Plattform 13. In der Gebrauchsstellung liegt die Plattform 13 auf der Oberseite der Gabelarme 5, 7 auf und wird von diesen abgestutzt. Die Plattform 13 weist eine ebene Abstellflache 19 auf, auf der Stuckguter 21A, 21B und 21C abstellt sind.Figure 5 shows a side view and Figure 6 is a plan view of the floor tool 1 with in the use position arranged platform 13. In the use position, the platform 13 rests on the top of the fork arms 5, 7 and is supported by them. The platform 13 has a flat storage surface 19 on which stucco goods 21A, 21B and 21C are placed.
An der Plattform 13 ist eine Anhangevorrichtung 23 zum Anhangen eines ein- oder mehrachsigen Anhangers vorgesehen, die hier von einem Anhangehaken 25 in Form eines Kugelkopfs gebildet ist, der mit einem Sattelanhanger koppelbar ist. Der Anhangehaken 25 ragt über die Abstellflache 19 hervor. Die Ausgestaltung der Anhangevorrichtung 23 ist nicht auf das in den Figuren dargestellte Ausfuhrungsbeispiel beschrankt, sondern kann -angepasst an den anzukuppelnden Anhanger- auch ein Kupplungsmaul oder dergleichen aufweisen. Bei in Gebrauchsstellung angeordneter Plattform 13 kann das Flurforderzeug 1 -wie aus den Figuren 5 und 6 ersichtlich- nicht nur zum Stuckguttransport eingesetzt werden, sondern es kann gleichzeitig auch noch ein Anhanger an die Anhangevorrichtung 23 angekuppelt werden.On the platform 13 there is an attachment device 23 for attaching a single-axle or multi-axle trailer, which is formed here by an attachment hook 25 in the form of a spherical head which can be coupled to a semi-trailer. The attachment hook 25 protrudes over the shelf 19. The design of the attachment device 23 is not limited to the exemplary embodiment shown in the figures, but can also have a coupling mouth or the like — adapted to the trailer to be coupled. When the platform 13 is arranged in the position of use, the floor tool 1 can - as can be seen from FIGS. 5 and 6 - not only be used for the transport of articles, but at the same time a trailer can also be coupled to the attachment device 23.
Aus den Figuren 1 bis 6 geht ferner hervor, dass das Flurforderzeug 1 ein Handbetatigungsmittel 27 zum Fuhren, Lenken und Rangieren und gegebenenfalls zum manuellen Ziehen desselben aufweist. Bei diesem Ausfuhrungsbeispiel weist das Flurforderzeug 1 mindestens drei Rader auf, von denen das dem Hubgerust 9 am nächsten angeordnete Rad lenkbar ist. Weitere Ausfuhrungsvarianten sind möglich.It can also be seen from FIGS. 1 to 6 that the floor tool 1 has a manual actuating means 27 for guiding, steering and maneuvering and, if appropriate, for manually pulling the same. In this exemplary embodiment, the ground vehicle 1 has at least three wheels, of which the wheel arranged closest to the lifting frame 9 can be steered. Other versions are possible.
Figur 7 zeigt eine Seitenansicht und Figur 8 eine Draufsicht auf das anhand der Figuren 1 bis 6 beschriebene Flurforderzeug 1, dessen Plattform 13 in Gebrauchsstellung herabgelassen ist und an dem ein Anhanger 29, hier ein Sattelanhanger, an die Anhangevorrichtung 23 angekuppelt ist . Figur 9 zeigt eine perspektivische Darstellung eines Ausfuhrungsbeispiel der Plattform 13, ahnlich wie die in den Figuren 1 bis 8 dargestellte Plattform. In Explosionsdarstellung sind Gelenke 31 und 33 dargestellt, an denen die Plattform 13 um die Achse 15 schwenkbeweglich anbringbar ist und die ihrerseits am Flurforderzeug 1, insbesondere am Gabeltrager 3, befestigt sind.FIG. 7 shows a side view and FIG. 8 shows a plan view of the floor tool 1 described with reference to FIGS. 1 to 6, the platform 13 of which is lowered in the use position and to which an attachment 29, here a semi-trailer, is coupled to the attachment device 23. FIG. 9 shows a perspective illustration of an exemplary embodiment of the platform 13, similar to the platform shown in FIGS. 1 to 8. In an exploded view, joints 31 and 33 are shown, to which the platform 13 can be pivotally attached about the axis 15 and which in turn are fastened to the floor tool 1, in particular to the fork carriage 3.
Um zu verhindern, dass die in Gebrauchsstellung herabgelassene Plattform 13 durch auf sie wirkende Querkräfte, die beispielsweise beim Beladen der Plattform 13 mit Stückgütern oder beim Bewegen des Flurforderzeugs eingeleitet werden können, auf den Gabelarmen 5, 7 verschoben wird, ist eine Querkraftabstutzungseinrichtung 35 vorgesehen, die hier von einer auf Unterseite der Plattform 13 angeordneten Leiste 37 gebildet ist. Die Leiste 37 ist quer zur Langserstreckung der Gabelarme 5, 7 ausgerichtet und derart ausgebildet, dass sie beim Verschwenken der Plattform 13 in die Gebrauchsstellung in den Freiraum zwischen die Gabelarme 5, 7 einfahrt. Sollten Querkrafte auf die Plattform 13 wirken, so schlagt die Leiste 37 am Gabelarm 5 beziehungsweise 7 an, wodurch eine Querverschiebung der Plattform 13 verhindert wird. Die Leiste 37 dient hier also als Anschlag.In order to prevent the platform 13 lowered in the position of use from being displaced on the fork arms 5, 7 by transverse forces acting on it, which can be introduced, for example, when loading the platform 13 with piece goods or when moving the ground vehicle, a lateral force support device 35 is provided. which is formed here by a bar 37 arranged on the underside of the platform 13. The strip 37 is aligned transversely to the longitudinal extension of the fork arms 5, 7 and is designed such that when the platform 13 is pivoted into the use position, it enters the space between the fork arms 5, 7. If transverse forces act on the platform 13, the bar 37 strikes the fork arm 5 or 7, thereby preventing the platform 13 from being displaced transversely. The bar 37 thus serves as a stop.
Zusammenfassend bleibt festzuhalten, dass das anhand der Figuren 1 bis 9 beschriebene Flurforderzeug 1 ein einfach umzurüstendes Kombigerat für den Palettentransport und ein (Sattel-) Schlepper für kurze bis sehr lange Anhanger ist. Die Funktion als Plattformwagen zur Mitnahme von unpalet- tiertem Stuckgut ist ein zusatzlicher Vorteil.In summary, it should be noted that the floor tool 1 described with reference to FIGS. 1 to 9 is an easily convertible combination device for pallet transport and a (semitrailer) tractor for short to very long trailers. The function as a platform trolley for taking unpaletted stucco is an additional advantage.
Das Flurforderzeug 1 ist besonders vorteilhaft zum Laden oder Beladen von Lastkraftwagen beziehungsweise -anhanger einsetzbar, die nur von hinten und nicht von der Seite zuganglich sind. Hierbei kann es vorkommen, dass wahrend eines Belade- beziehungsweise Entladevorgangs mehrmals wech- selnd die Anhangevorrichtung, der Gabeltrager und die Plattform mit ihrer Abstellflache für unpalletiertes Stuckgut benotigt werden, was bei dem erfindungsgemaßen Flurforderzeug 1 -anders als bei dem bekannten Flurforderzeug- ohne weiteres schnell und in einfacher Weise durch herunter- beziehungsweise hochklappen der Plattform mög The industrial vehicle 1 can be used particularly advantageously for loading or loading trucks or trailers which are only accessible from the rear and not from the side. It can happen that several times during a loading or unloading process selnd the attachment device, the fork carriage and the platform with their storage space for unpalleted stucco are needed, which is possible with the inventive floor tool 1 - unlike the known floor tool - easily and quickly by folding the platform down or up
