Ein gattungsgemäßes Flurförderzeug mit einer relativ zum Fahrzeugrahmen horizontal verschiebbaren Aufstandsfläche für den Batterieblock ist beispielsweise in der nachveröffentlichten Patentanmeldung DE102004056624.0 beschrieben. Gemeinsam mit der Aufstandsfläche kann der Batterieblock vollständig aus dem Batteriefach heraus bewegt werden. Von dort kann der Batterieblock dann beispielsweise mittels eines Hallenkrans weiter transportiert werden. Die bewegliche Führung der Aufstandsfläche ist mit Hilfe von Rollen realisiert, wobei die Aufstandsfläche mittels Rollen an einem Zwischenelement geführt ist und das Zwischenelement mittels Rollen an dem Fahrzeugrahmen des Flurförderzeugs geführt ist. Zur Führung der Rollen des Zwischenelements befindet sich an dem Fahrzeugrahmen eine Rollbahn.One generic truck with a relative to the vehicle frame horizontally displaceable footprint for the battery pack is for example in the post-published patent application DE102004056624.0 described. Together with the footprint can the battery pack completely be moved out of the battery compartment. From there, the battery pack then be transported for example by means of a hall crane on. The mobile leadership the footprint is realized by means of roles, the footprint using Rollers is guided on an intermediate element and the intermediate element is guided by means of rollers on the vehicle frame of the truck. To the leadership the roles of the intermediate element is located on the vehicle frame a runway.
Wenn sich der Batterieblock auf der Aufstandsfläche befindet, also auch während des Betriebs des Flurförderzeugs, ist die Gewichtskraft des Batterieblocks ständig über die Rollen an der Rollbahn abgestützt. Diese fortlaufende Krafteinwirkung stellt für die Rollen und die Rollbahnen eine erhebliche Beanspruchung dar, weshalb diese Bauteile entweder einem schnellen Verschleiß unterliegen oder besonders großzügig dimensioniert werden müssen.If the battery block is on the footprint, including during the Operation of the truck, the weight of the battery pack is constantly over the rollers on the runway supported. This continuous force provides for the rollers and the runways a significant stress, which is why these components either subject to rapid wear or especially generously dimensioned Need to become.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Flurförderzeug der eingangs genannten Art zur Verfügung zu stellen, bei dem die Führung der Aufstandsfläche bei geringem Verschleiß mit einfachen Bauteilen realisierbar ist.Of the present invention is based on the object, a truck to provide the type mentioned, in which the Leadership of footprint with low wear with simple components can be realized.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die am Fahrzeugrahmen angeordnete Rollbahn mindestens eine Vertiefung aufweist, die derart angeordnet ist, dass bei vollständig eingeschobener Aufstandsfläche mindestens eine Rolle in eine Vertiefung eingerastet ist. Während des Betriebs des Flurförderzeugs greift die Rolle also in die Vertiefung ein und ist damit entlastet. Gleichzeitig ist durch den Eingriff der Rolle in die Vertiefung die Position des Batterieblocks relativ zum Fahrzeugrahmen definiert, sodass eine Bewegung des Batterieblocks innerhalb des Batteriefachs verhindert ist.These Task is inventively characterized solved, that arranged on the vehicle frame runway at least one Well, which is arranged such that when fully inserted footprint at least one roller is engaged in a recess. During the Operation of the truck engages the role so in the deepening and is thus relieved. At the same time, the engagement of the roller in the recess defines the position of the battery pack relative to the vehicle frame, allowing movement of the battery pack inside the battery compartment is prevented.
Gemäß einer zweckmäßigen Ausgestaltung der Erfindung sind die Rollen, die an der am Fahrzeugrahmen angeordneten Rollbahn geführt sind, an zwei zueinander parallelen Achsen angeordnet, die sich bei vollständig eingeschobener Aufstandsfläche – in Bewegungsrichtung der Aufstandsfläche betrachtet – im Bereich des vorderen und des hinteren Endes der Aufstandsfläche befinden. Damit sind für die Rollen, die der Rollbahn des Fahrzeugrahmens zugeordnet sind, eine vordere und eine hintere Rollenachse vorgesehen. Dementsprechend weist die Rollbahn des Fahrzeugrahmens genau zwei Vertiefungen auf, deren Abstand dem Abstand der Rollenachsen entspricht.According to one appropriate embodiment of Invention are the rollers which are arranged on the vehicle frame Runway led are arranged on two mutually parallel axes, which at complete inserted footprint - in the direction of movement the footprint considered - im Area of the front and rear end of the footprint. This is for the Rolls associated with the runway of the vehicle frame, a provided front and a rear roller axle. Accordingly the taxiway of the vehicle frame has exactly two depressions, whose distance corresponds to the distance between the roller axes.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist an der Aufstandsfläche mindestens eine ausfahrbare Stützrolle angeordnet, mit der bei zumindest teilweise ausgefahrener Aufstandsfläche ein Teil der Gewichtskraft des Batterieblocks an einer Fahrbahn abstützbar ist. Die Stützrolle verhindert ein Abkippen des Batterieblocks, wenn die Rollen einer der beiden Rollenachse sich außerhalb des Batteriefachs befinden und damit keine Momente mehr abgestützt werden können. Wenn sich die Aufstandsfläche innerhalb des Batteriefachs befindet, ist die Stützrolle eingefahren und beansprucht damit nur wenig Bauraum. Die ausgefahrene Stützrolle ist starr mit der Aufstandsfläche verbunden und rollt während eines Verschiebens der Aufstandsfläche an der Fahrbahn ab.According to one advantageous development of the invention is at the footprint at least an extendable support roller arranged, with the at least partially extended footprint a Part of the weight of the battery pack can be supported on a roadway. The support roller Prevents tilting of the battery block when the rollers of a the two roller axis are outside located in the battery compartment and are therefore no longer supported moments can. When the footprint is inside the battery compartment, the support roller is retracted and stressed so little space. The extended support roller is rigidly connected to the footprint and rolls during one Moving the footprint off at the roadway.
Eine weitere zweckmäßige Weiterbildung der Erfindung besteht darin, dass zwischen dem Fahrzeugrahmen und der Aufstandsfläche ein parallel zu der Aufstandsfläche bewegbares Zwischenelement angeordnet ist, wobei an dem Zwischenelement Rollen drehbar gelagert sind, die auf der am Fahrzeugrahmen angeordneten Rollbahn abrollen, und an der Aufstandsfläche Rollen drehbar gelagert sind, die an einer am Zwischenelement angeordneten Rollbahn abrollen. Mittels des Zwischenelements wird eine teleskopische Ausfahrbarkeit der Aufstandsfläche realisiert. Es ist damit gewährleistet, dass die Aufstandsfläche vollständig aus dem Batteriefach heraus bewegt werden kann.A further expedient development of Invention is that between the vehicle frame and the footprint one parallel to the footprint movable intermediate element is arranged, wherein on the intermediate element Rollers are rotatably mounted, which are arranged on the vehicle frame Roll the runway, and rollers are rotatably mounted on the footprint, which roll on a runway arranged on the intermediate element. By means of the intermediate element is a telescopic extensibility the footprint realized. It is guaranteed that the footprint Completely can be moved out of the battery compartment.
Die am Zwischenelement angeordnete Rollbahn weist ebenfalls mindestens eine Vertiefung auf, die derart angeordnet ist, dass bei vollständig eingeschobener Aufstandsfläche eine Rolle in die Vertiefung eingerastet ist. Es ist damit gewährleistet, dass auch diejenigen Rollen, die auf der Rollbahn des Zwischenelements abrollen, während des Betriebs des Flurförderzeugs entlastet sind. Gleichzeitig wird eine unerwünschte Bewegung der Aufstandsfläche relativ zum Zwischenelement verhindert.The arranged on the intermediate element runway also has at least one recess which is arranged such that when fully inserted footprint a role is engaged in the recess. It is thus ensured that even those rollers that roll on the runway of the intermediate element, are relieved during operation of the truck. At the same time, an undesired movement of the footprint becomes relative prevents the intermediate element.
Gemäß einer Weiterbildung der Erfindung ist ein krafterzeugendes Mittel zum horizontalen Bewegen des Batterieblocks vorgesehen. Damit muss die zum Bewegen des Batterieblocks erforderliche Kraft nicht direkt von Hand auf den Batterieblock ausgeübt werden. Das krafterzeugende Mittel kann beispielsweise von einem elektrischen, hydraulischen oder pneumatischen Stellglied gebildet sein. Möglich ist auch die Ausführung des krafterzeugenden Stellglieds als manuell angetriebenes Übersetzungsgetriebe.According to one Further development of the invention is a force-generating means for horizontal movement of the battery block provided. This must be the to Moving the battery pack does not require force directly from Hand on the battery block to be exercised. The force-generating means may be, for example, an electrical, be formed hydraulic or pneumatic actuator. It is also possible execution the force-generating actuator as a manually driven transmission gear.
Besonders einfach ist es, wenn das krafterzeugende Mittel ausschließlich zum Überwinden der erhöhten Kraft vorgesehen ist, die während des Bewegens der mindestens einen Rolle aus der ihr zugeordneten Vertiefung aufzubringen ist. Das krafterzeugende Stellglied wird also nur eingesetzt, um die Rollen aus den Vertiefungen heraus auf die ebenen Rollbahnen zu bewegen. Anschließend kann die zum Bewegen des Batterieblocks erforderliche Kraft direkt von Hand auf den Batterieblock ausgeübt werden.Especially it is easy when the force-generating means solely to overcome the heightened Force is provided during the moving the at least one roller from its associated Is to raise well. The force-generating actuator is So only used to get the rollers out of the recesses to move the flat taxiways. Then you can move to the Battery block required force directly by hand on the battery pack exercised become.
