Description

Die Erfindung betrifft einen Gabelstapler mit einem Rahmen und einem innerhalb des Rahmens angeordneten Batterieblock, wobei der Rahmen eine seitliche Öffnung zur Entnahme des Batterieblocks in im Wesentlichen horizontaler Richtung aufweist.The invention relates to a forklift with a frame and one within the Frame arranged battery block, the frame having a side opening for Has removal of the battery pack in a substantially horizontal direction.

Ein elektrisch angetriebener Gabelstapler der genannten Art ist mit einem mit Akkumulatoren bestückten Batterieblock ausgerüstet, der die für den Fahrantrieb, den Hubantrieb und sonstige elektrische Aggregate erforderliche Energie zur Verfügung stellt. Um den Batterieblock beispielsweise im Schadensfall auswechseln zu können, ist der Rahmen des Gabelstaplers derart ausgebildet, dass der Batterieblock mittels einer geeigneten Vorrichtung entfernt und ein neuer Batterieblock eingesetzt werden kann. Ein besonders häufiges Wechseln des Batterieblocks ist dann erforderlich, wenn der Gabelstapler im Mehrschichtbetrieb eingesetzt wird. In diesem Fall wird regelmäßig ein im Gabelstapler befindlicher entladener Batterieblock durch einen frisch geladenen Batterieblock ersetzt.An electrically powered forklift of the type mentioned is with a Accumulators equipped battery block equipped for the drive, the Lift drive and other electrical units required energy available provides. In order to be able to replace the battery block, for example in the event of damage, the frame of the forklift is designed such that the battery block by means of removed using a suitable device and a new battery pack inserted can. A particularly frequent change of the battery pack is necessary if the forklift is used in multi-shift operation. In this case it becomes regular a discharged battery block in the forklift by a freshly charged one Battery block replaced.

Bekannt ist es, den Rahmen des Gabelstaplers derart auszuführen, dass der Batterieblock mit einem Kran nach oben entnommen werden kann. Nachteilig hieran ist, dass die über dem Batterieblock befindlichen Bauteile, in der Regel eine Fahrerkabine und ein Fahrerschutzdach, zumindest teilweise verschwenkbar ausgeführt werden müssen, um ein Herausheben des Batterieblocks zu ermöglichen.It is known to design the frame of the forklift in such a way that the Battery block can be removed with a crane. The disadvantage of this is that the components located above the battery block, usually one Driver's cabin and a canopy, at least partially pivotable must be carried out to enable the battery pack to be lifted out.

Bei bekannten gattungsgemäßen Gabelstaplern mit seitlicher Batterieentnahmeöffnung ist am Boden des Batteriefachs im Gabelstapler eine Rollenbahn angeordnet. Von dieser gabelstaplerfesten Rollenbahn kann der Batterieblock in horizontaler Richtung auf eine neben dem Gabelstapler angeordnete externe Rollenbahn geschoben werden. Damit der Rahmen des Gabelstaplers trotz der großen seitlichen Öffnung für den Batterieblock die erforderliche Steifigkeit aufweist, ist es bekannt, ein unterhalb und seitlich der Öffnung verlaufendes Profil vorzusehen, auf dem auch die Gewichtskraft des Batterieblocks abgestützt wird. Ein derartiger Gabelstapler ist beispielsweise in der DE 100 05 285 A1 beschrieben. Nachteilig an dieser bekannten Anordnung ist, dass die Rollenbahnen zum Batteriewechsel zwingend erforderlich sind. In known generic forklift trucks with a side battery removal opening a roller conveyor is arranged on the bottom of the battery compartment in the forklift. Of This forklift-fixed roller conveyor can move the battery block in a horizontal direction be pushed onto an external roller conveyor located next to the forklift. So that the frame of the forklift despite the large side opening for the Battery pack has the required rigidity, it is known to be one below and to provide a profile to the side of the opening, on which the weight is also applied of the battery pack is supported. Such a forklift is for example in the DE 100 05 285 A1. A disadvantage of this known arrangement is that the roller conveyors for changing the batteries are absolutely necessary.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Gabelstapler so auszubilden, dass der im Gabelstapler befindliche Batterieblock unterfahren und beispielsweise mittels eines Gabelhubwagens angehoben und durch die seitliche Öffnung des Rahmens bewegt werden kann.The present invention is based on the object of a forklift to train that the battery block in the forklift is driven under and for example raised by means of a pallet truck and through the side Opening of the frame can be moved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Rahmen einen auf Biegung belastbaren Träger aufweist, der an der Oberseite der Öffnung des Rahmens angeordnet ist. Der im Wesentlichen horizontal, in Längsrichtung des Gabelstaplers angeordnete Träger verleiht dem Rahmen die erforderliche Steifigkeit, wobei der Träger hauptsächlich eine Biegebelastung erfährt. Der Träger bildet dabei den oberen Rand der Rahmenöffnung. Durch die Anordnung des Trägers oberhalb des Batteriefachs bleibt der Raum unterhalb des Batterieblocks frei von tragenden Rahmenteilen. Hierdurch wird es beispielsweise möglich, den Batterieblock mit einem lastrollenunterstützten Gabelhubwagen, der unter den Gabelstapler geschoben wird, anzuheben und herauszuziehen.This object is achieved in that the frame one Bend has resilient support at the top of the opening of the frame is arranged. The essentially horizontal, in the longitudinal direction of the forklift arranged carrier gives the frame the required rigidity, the Carrier mainly experiences a bending load. The carrier forms the upper one Edge of the frame opening. By placing the carrier above the Battery compartment, the space below the battery block remains free of load-bearing Frame parts. This makes it possible, for example, to use a Pallet truck supported by load rollers, which is pushed under the forklift, to lift and pull out.

Gemäß einer zweckmäßigen Weiterbildung der Erfindung ist der Träger derart geformt, dass er sich auf die Vorderseite der Öffnung des Rahmens erstreckt. Der Träger geht dabei von dem waagrechten Abschnitt an der Oberseite der Öffnung in einen im Wesentlichen senkrechten Abschnitt über. Der senkrechte Abschnitt bildet dabei den vorderen Rand der Rahmenöffnung.According to an expedient development of the invention, the carrier is shaped in such a way that that it extends to the front of the opening of the frame. The carrier leaves doing so from the horizontal section at the top of the opening into an Essentially vertical section above. The vertical section forms the front edge of the frame opening.

Ebenso zweckmäßig ist es, wenn der Träger derart geformt ist, dass er sich auf die Hinterseite der Öffnung des Rahmens erstreckt. Auch hier bildet dann ein im Wesentlichen senkrechter Abschnitt des Trägers den hinteren Rand der Rahmenöffnung.It is also expedient if the carrier is shaped in such a way that it relates to the Extends behind the opening of the frame. Here too, an im Substantially vertical section of the beam the rear edge of the Frame opening.

Der Rahmen des Gabelstaplers ist im Bereich des Batterieblocks nach unten zumindest teilweise offen. Die Öffnung des Rahmens ist derart bemessen, dass die Gabeln eines zum Transport des Batterieblocks vorgesehenen Hubwagens direkt mit dem Batterieblock in Kontakt treten können. Ebenso weist der Rahmen im Bereich unterhalb des Batterieblocks Aufstandspunkte für den Batterieblock auf, über welche die Gewichtskraft des Batterieblocks in den Rahmen eingeleitet wird. The forklift frame is down in the area of the battery pack at least partially open. The opening of the frame is dimensioned such that the Forks of a pallet truck intended for transporting the battery block directly with can contact the battery pack. The frame also points in the area below the battery block, contact points for the battery block, via which the weight of the battery pack is introduced into the frame.

Eine vorteilhafte Ausgestaltung liegt vor, wenn der Träger im vorderen Bereich starr mit einer Aufnahme für eine Vorderachse des Gabelstaplers verbunden ist. Von der Vorderachse ausgehende Kräfte und Momente können somit direkt in den Träger eingeleitet werden. Der Träger kann starr mit der Aufnahme verbunden, beispielsweise verschweißt oder verschraubt sein. Ebenso ist es möglich, den Träger und die Aufnahme für die Vorderachse als gemeinsames Bauteil, also einstückig auszubilden.An advantageous embodiment is when the carrier is rigid with the front area a receptacle for a front axle of the forklift is connected. Of the Forces and moments emanating from the front axle can therefore be carried directly into the beam be initiated. The carrier can be rigidly connected to the receptacle, for example welded or screwed. It is also possible to choose the carrier and the Support for the front axle as a common component, i.e. to be made in one piece.

Weiter ist es vorteilhaft, wenn der Träger im hinteren Bereich starr mit einem Heckgewicht des Gabelstaplers verbunden ist. Der Träger ist dabei vorzugsweise mittels einer Schraubenverbindung direkt mit dem gegossenen Heckgewicht verbunden. Die auf den Träger wirkenden Kräfte können dadurch direkt in das Heckgewicht eingeleitet werden.It is also advantageous if the carrier is rigid with one in the rear area Rear weight of the forklift is connected. The carrier is preferred by means of a screw connection directly with the cast rear weight connected. The forces acting on the carrier can thereby directly into the Rear weight can be initiated.

Eine hohe Biegesteifigkeit des Trägers bei gleichzeitig geringem Materialeinsatz wird erreicht, wenn der Träger ein zumindest annähemd T-förmiges Profil aufweist.A high bending stiffness of the beam combined with a low use of materials achieved when the carrier has an at least approximately T-shaped profile.

Die gleichen Vorteile ergeben sich, wenn der Träger zumindest teilweise als Hohlprofil ausgebildet ist.The same advantages result if the carrier is at least partially as a hollow profile is trained.

The battery compartment 1 is at the top by a Sheet 3 limited, forward by another sheet 4.

Um dem Rahmen die erforderliche Steifigkeit zu verleihen, ist erfindungsgemäß direkt oberhalb des Batteriefachs, an dessen offener Seite, ein sich in Längsrichtung des Gabelstaplers erstreckender Träger 5 angeordnet. Der Träger 5 ist das tragende Rahmenteil auf der rechten Gabelstaplerseite und dient zur Übertragung von Kräften und Momenten zwischen dem vorderen und dem hinteren Teil des Gabelstaplers. In seinem vorderen Bereich knickt er Träger 5 nach unten ab und verläuft entlang des vorderen Blechs 4 des Batteriefachs 1. Der Träger 5 ist im vorderen Bereich starr mit einer Aufnahme 6 für die Vorderachse des Gabelstaplers verbunden. Im hinteren Bereich ist der Rahmen, und damit direkt oder indirekt auch der Träger 5, starr mit einem Heckgewicht des Gabelstaplers verbunden, wofür im vorliegenden Ausführungsbeispiel Schraubenlöcher 7 vorgesehen sind.In order to give the frame the required rigidity, the invention is direct Above the battery compartment, on the open side, a in the longitudinal direction of the Forklift extending carrier 5 arranged. The carrier 5 is the load-bearing one Frame part on the right side of the forklift and is used to transfer forces and moments between the front and rear of the forklift. In In its front area it bends carrier 5 downwards and runs along the front plate 4 of the battery compartment 1. The carrier 5 is rigid with in the front area a receptacle 6 connected to the front axle of the forklift.

Die Gabeln des Gabelhubwagens befinden sich während des Entfernens oder Einsetzens eines Batterieblocks zwischen den am Rahmen angeordneten Aufstandspunkten 8, auf denen der Batterieblock während des Betriebs des Gabelstaplers steht.The battery compartment 1, which is open at the bottom, makes it impossible to change one battery blocks shown with a pallet truck under the battery compartment drive, lift the battery pack and move it out of the battery compartment. A new battery pack is inserted in the reverse order. The Forks of the pallet truck are in the process of being removed or inserted a battery block between the uprising points 8 arranged on the frame which the battery pack stands during the operation of the forklift.

Die Figuren 2 bis 4 zeigen verschiedene Varianten zur Gestaltung des Querschnitts des Trägers 5. Die Querschnittsformen sind dabei so gewählt, dass der Träger 5 hohe Widerstandsmomente bezüglich Drehmomenten um eine horizontale oder vertikale Achse aufweist. Gleichzeitig soll der Träger mit möglichst geringem Materialeinsatz und damit kostengünstig herstellbar sein. Die im Folgenden beschriebenen Querschnitte können in der Anwendung als Träger in der dargestellten Ausrichtung, oder um 180 Grad gedreht eingesetzt werden.Figures 2 to 4 show different variants for the design of the cross section of the carrier 5. The cross-sectional shapes are chosen so that the carrier 5 high Resistance moments with respect to torques around a horizontal or vertical Axis. At the same time, the carrier should use as little material as possible and thus be inexpensive to manufacture. The ones described below Cross-sections can be used in the orientation shown, or rotated 180 degrees.

In der Variante gemäß Figur 2 weist der Träger ein T-förmiges Profil auf und besteht aus einem waagrechten Blech 10 und einem darauf aufgesetzten senkrechten Blech 11. Die beiden Bleche 10, 11 können beispielsweise miteinander verschweißt sein.In the variant according to Figure 2, the carrier has a T-shaped profile and exists from a horizontal plate 10 and a vertical plate placed thereon 11.
