Description

Die Erfindung betrifft ein Flurförderzeug mit einem Batteriefach und einem in horizontaler Richtung in das Batteriefach hinein und aus dem Batteriefach heraus bewegbaren Batterieblock, wobei das Batteriefach eine oberhalb des Batterieblocks angeordnete bewegbare Abdeckhaube aufweist und für die Abdeckhaube eine geöffnete Stellung und eine geschlossene Stellung vorgesehen ist.The invention relates to an industrial truck with a battery compartment and an in horizontal direction into and out of the battery compartment movable battery block, the battery compartment one above the battery block arranged movable cover and has a cover for the cover open position and a closed position is provided.

Bei Flurförderzeugen dieser Art, z. B. Hubwagen oder Kommissioniergeräten, werden der Fahrantrieb und Zusatzaggregate, wie z. B. eine Hubvorrichtung, von in dem Batterieblock angeordneten Akkumulatoren mit elektrischer Energie versorgt. Es ist dabei regelmäßig, nach einer von den Einsatzbedingungen des Flurförderzeugs abhängigen Betriebsdauer, ein Aufladen der Akkumulatoren erforderlich. Um lange Standzeiten des Flurförderzeugs zu vermeiden, kann alternativ zu einem Aufladen der im Flurförderzeug befindlichen Akkumulatoren der komplette Batterieblock ausgetauscht werden. Gattungsgemäße Flurförderzeuge weisen hierzu ein seitlich offenes Batteriefach auf. Durch die seitliche Öffnung kann der alte Batterieblock in horizontaler Richtung aus dem Batteriefach heraus geschoben und anschließend ein neuer Batterieblock mit frisch aufgeladenen Akkumulatoren in das Batteriefach hinein geschoben werden. Hierzu wird in der Regel eine geeignete Hilfsvorrichtungen, wie z. B. eine Rollenbahn, verwendet.In industrial trucks of this type, for. B. pallet trucks or order pickers the travel drive and additional units, such as. B. a lifting device, in which Battery block arranged batteries supplied with electrical energy. It is regularly, according to one of the operating conditions of the industrial truck dependent operating time, the batteries need to be charged. Long time Avoiding downtimes of the industrial truck can alternatively charge the truck the entire battery pack in the truck be replaced. Generic industrial trucks have a side for this open battery compartment. Through the side opening, the old battery pack can be pushed horizontally out of the battery compartment and then on New battery block with freshly charged batteries in the battery compartment be pushed. For this purpose, suitable auxiliary devices, such as e.g. B. a roller conveyor used.

Oberhalb des Batterieblocks befindet sich eine bewegbare Abdeckhaube. Die Abdeckhaube kann in eine geöffnete Stellung geklappt werden, um die Pole der Akkumulatoren mit den Batterieanschlußleitung des Flurförderzeugs verbinden zu können. Während des Betriebs des Flurförderzeugs bleibt die Abdeckhaube geschlossen, so daß die Pole und die Anschlußleitungen vor ungewolltem Zugriff geschützt sind.There is a movable cover above the battery block. The Cover can be folded into an open position to the poles of the Connect the batteries to the battery connection cable of the industrial truck can. The cover remains in place while the truck is operating closed, so that the poles and the connecting lines from accidental access are protected.

Während des Betriebs des Flurförderzeugs ist der Batterieblock innerhalb des Batteriefachs befestigt. Es wird damit ein mögliches Verrutschen oder Herausfallen das Batterieblocks durch die seitliche Öffnung des Batteriefachs, infolge einer seitlichen Neigung des Flurförderzeugs oder infolge von Fliehkräften, verhindert. Durch die Befestigung des Batterieblocks wird auch bei einem Umkippen des Flurförderzeugs infolge eines Unfalls ein Herausfallen des Batterieblocks durch die sich dabei möglicherweise öffnende Abdeckhaube verhindert.The battery pack is inside the truck while it is in operation Battery compartment attached. This will cause it to slip or fall out the battery block through the side opening of the battery compartment, as a result of prevents the truck from tilting sideways or as a result of centrifugal forces. By The battery block is also fastened if the truck tips over  as a result of an accident, the battery pack falls out possibly opening cover hood prevented.

Flurförderzeuge des Standes der Technik weisen zur Befestigung des Batterieblocks aufwendige Klemmvorrichtungen auf, die während des Auswechselns des Batterieblocks in mehreren Arbeitsschritten gelöst und wieder gespannt werden müssen. Im übrigen werden hierfür in der Regel Batterieblöcke mit besonders angepaßter Formgebung benötigt, was einen hohen Aufwand bei der Herstellung des Batterieblocks erfordert.Industrial trucks of the prior art have for fastening the battery block elaborate clamping devices that during the replacement of the Battery blocks can be loosened and re-tensioned in several steps have to. Incidentally, battery blocks are usually used for this purpose adapted shape required, which is a high cost in the manufacture of Battery packs required.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Flurförderzeug mit einem Batteriefach zur Verfügung zu stellen, bei dem ein Auswechseln des Batterieblocks mit wenigen Arbeitsschritten möglich ist.The present invention has for its object to provide an industrial truck with a To provide battery compartment, in which a replacement of the battery block with a few steps is possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mit der Abdeckhaube mindestens ein Mittel zum Fixieren des Batterieblocks in horizontaler Richtung in Wirkverbindung steht, welches bei geschlossener Abdeckhaube wirksam und bei geöffneter Abdeckhaube unwirksam ist.This object is achieved in that with the cover at least one means for fixing the battery pack in the horizontal direction in There is an active connection, which is effective when the cover is closed and at open cover is ineffective.

Durch die Wirkverbindung der Abdeckhaube mit dem Mittel zum Fixieren des Batterieblocks wird bei einem Öffnen der Abdeckhaube der Batterieblock automatisch freigegeben, so daß er relativ zu dem Batteriefach bewegt werden kann. Analog hierzu wird ein in dem Batteriefach befindlicher Batterieblock automatisch in seiner Position fixiert, wenn die Abdeckhaube geschlossen wird. Durch diese erfindungsgemäße Wirkverbindung reduziert sich die Anzahl der bei einem Auswechseln des Batterieblocks erforderlichen Arbeitsschritte deutlich. Eine Bewegung des Batterieblocks relativ zu dem Batteriefach des Flurförderzeugs ist somit bei geschlossener Abdeckhaube ausgeschlossen.Through the operative connection of the cover with the means for fixing the The battery block becomes automatic when the cover is opened released so that it can be moved relative to the battery compartment. Analogously to this a battery block located in the battery compartment is automatically in its position fixed when the cover is closed. Through this invention Active connection reduces the number of when the Battery blocks required work steps clearly. A movement of the Battery blocks relative to the battery compartment of the truck is thus at closed cover excluded.

Vorteilhafterweise ist der Batterieblock bei geöffneter Abdeckhaube in horizontaler Querrichtung des Flurförderzeugs in das Batteriefach hinein und aus dem Batteriefach heraus bewegbar. Die Breite des Batteriefachs entspricht dabei in etwa der Breite des Flurförderzeugs, so daß mindestens eine Seitenwand des Batterieblocks gleichzeitig den seitlichen Abschluß des Flurförderzeugs bildet. Zumindest auf einer Seite des Batterieblocks befinden sich keinerlei Elemente eines Rahmens oder Gehäuses des Flurförderzeugs, so daß der entriegelte Batterieblock ohne weitere Arbeitsschritte in seitlicher Richtung horizontal aus dem Batteriefach hinaus bzw. in das Batteriefach hinein geschoben werden kann.The battery block is advantageously horizontal when the cover is open Transverse direction of the industrial truck into and out of the battery compartment movable out. The width of the battery compartment corresponds approximately to the width of the Industrial truck so that at least one side wall of the battery pack at the same time forms the lateral end of the truck. At least on one side of the Battery blocks are no elements of a frame or housing of the Industrial truck, so that the unlocked battery block in without further steps  sideways horizontally out of the battery compartment or into the battery compartment can be pushed into it.

In einer zweckmäßigen Weiterbildung der Erfindung ist die Abdeckhaube schwenkbar um eine in horizontaler Querrichtung des Flurförderzeugs angeordnete Achse gelagert.In an expedient development of the invention, the cover can be pivoted mounted around an axis arranged in the horizontal transverse direction of the industrial truck.

In einer besonders zweckmäßige Ausgestaltung ist als Mittel zum Fixieren des Batterieblocks mindestens ein Halteblech vorgesehen, welches an der Abdeckhaube befestigt ist. Die Haltebleche sind an der Unterseite der Abdeckhaube angeordnet und werden mit der Abdeckhaube nach oben bzw. nach unten mitgeschwenkt. Bei geschlossener Abdeckhaube stehen die Haltebleche derart in Eingriff mit einem Gehäuseteil des Batterieblocks, daß eine seitliche Bewegung des Batterieblocks ausgeschlossen ist. Die Haltebleche können zu diesem Zweck derart gestaltet werden, daß sie in Verbindung mit genormten Batterieblöcken verwendet werden können. Mit dieser Ausgestaltungsform ist auch die Anzahl der benötigten Bauteile auf ein Minimum reduziert. Bei einem Öffnen der Abdeckhaube werden die Haltebleche in den Bereich oberhalb des Batterieblocks bewegt, so daß der Batterieblock dann in seitlicher Richtung bewegt werden kann.In a particularly expedient embodiment, the means for fixing the Battery blocks provided at least one retaining plate, which on the cover is attached. The holding plates are arranged on the underside of the cover and are swiveled up or down with the cover. At closed cover, the retaining plates are in engagement with one Housing part of the battery block that a lateral movement of the battery block is excluded. For this purpose, the holding plates can be designed in such a way that that they can be used in conjunction with standardized battery blocks. With This embodiment also includes the number of components required Minimum reduced. When you open the cover, the retaining plates are in the Area moved above the battery pack, so that the battery pack then in can be moved laterally.

Eine vorteilhaft Weiterbildung der Erfindung besteht darin, daß Mittel zum Verriegeln der Abdeckhaube in geschlossener Stellung vorgesehen sind. Durch die Verriegelung der Abdeckhaube ist sichergestellt, daß sich die Abdeckhaube, z. B. bei einem Unfall, nicht selbständig öffnet. Es wird damit einerseits ein Herausfallen des Batterieblocks aus dem Batteriefach in Richtung der Abdeckhaube verhindert. Andererseits ist dadurch ebenfalls sichergestellt, daß die Mittel zum Fixieren des Batterieblocks auch bei einem Unfall oder bei einem Umkippen des Flurförderzeugs wirksam bleiben.An advantageous development of the invention is that means for locking the cover are provided in the closed position. By locking the cover ensures that the cover, z. B. in an accident, does not open automatically. On the one hand, the battery block will fall out prevented from the battery compartment in the direction of the cover. On the other hand this also ensures that the means for fixing the battery block also remain effective in the event of an accident or if the truck tips over.

Weitere Vorteile und Einzelheiten der Erfindung werden anhand des in den schematischen Figuren dargestellten Ausführungsbeispiels näher erläutert. Dabei zeigtFurther advantages and details of the invention are based on the in the schematic figures illustrated embodiment explained in more detail. It shows

Fig. 1 ein gattungsgemäßes Flurförderzeug, Fig. 1, a generic industrial truck,

Fig. 2, 3 und 4 ein erfindungsgemäßes Batteriefach in verschiedenen Ansichten. Fig. 2, 3 and 4, an inventive battery compartment in different views.

In Fig. 1 ist als gattungsgemäßes Flurförderzeug ein Niederhubkommissionierer dargestellt. Das Flurförderzeug besteht aus einem Antriebsteil 1 und einem Lastteil 2. Der Antriebsteil weist einen Fahrerstand 3 auf. In dieser Abbildung nicht dargestellt sind im Bereich des Antriebsteils 1 angeordnete Bedienelemente zur Steuerung von in dem Gehäuse 4 befindlichen Antriebsaggregaten und Zusatzaggregaten. Der Lastteil 2 weist ein als Lastgabel ausgeführtes Lastaufnahmemittel 5 sowie ein Batteriefach 6 auf, in welchem ein Batterieblock 7 angeordnet ist. Um auf dem Lastaufnahmemittel 5 befindliche Lasten gegenüber der Fahrbahnoberfläche anzuheben, kann der komplette Lastteil 2 relativ zu dem Antriebsteil 1 mittels einer Hubvorrichtung nach oben bewegt werden.In Fig. 1, a Low level is shown as a generic truck. The industrial truck consists of a drive section 1 and a load section 2 . The drive part has a driver's station 3 . Not shown in this figure are operating elements arranged in the area of the drive part 1 for controlling drive units and additional units located in the housing 4 . The load part 2 has a load suspension means 5 designed as a load fork and a battery compartment 6 , in which a battery block 7 is arranged. To lift on the load receiving means 5 located loads with respect to the road surface, the entire load unit 2 can be relative to the drive member 1 by means of a lifting device moving upwards.

Das in Querrichtung des Flurförderzeugs offene Batteriefach 6 ist in Fig. 2 vergrößert dargestellt. Das Batteriefach 6 besteht im wesentlichen aus zwei zueinander zumindest annähernd parallelen Begrenzungswänden 8 und einer an der Oberkante einer der Begrenzungswände 8 angeordnete Abdeckhaube 9. Die in geöffneter Stellung dargestellte Abdeckhaube 9 ist dabei schwenkbar um eine horizontale, sich in Querrichtung des Flurförderzeugs erstreckende Achse 10 gelagert.The battery compartment 6, which is open in the transverse direction of the industrial truck, is shown enlarged in FIG. 2. The battery compartment 6 consists essentially of two at least approximately parallel boundary walls 8 and a cover 9 arranged on the upper edge of one of the boundary walls 8 . The cover 9 shown in the open position is pivotally mounted about a horizontal axis 10 extending in the transverse direction of the industrial truck.

Zwischen den beiden Begrenzungswänden 8 ist bei geöffneter Abdeckhaube 9 der Batterieblock 7 frei verschiebbar. An der Abdeckhaube 9 sind in diesem Ausführungsbeispiel als erfindungsgemäße Mittel zum Fixieren des Batterieblocks 7 zwei Haltebleche 11 befestigt. Bei vollständig in das Batteriefach 6 eingeschobenem Batterieblock 7 und geschlossener Abdeckhaube 9 stehen die Haltebleche 11 an der Innenseite des jeweiligen Seitenteils 12 des Batterieblocks 7 an. Ein Verrutschen des Batterieblocks 7 wird somit in beide Richtungen verhindert.When the cover 9 is open, the battery block 7 can be moved freely between the two boundary walls 8 . 7, two holding plates 11 are fixed to the cover 9 in this embodiment according to the invention as a means for fixing the battery block. When the battery block 7 is fully inserted into the battery compartment 6 and the cover 9 is closed, the holding plates 11 are in contact with the inside of the respective side part 12 of the battery block 7 . Slipping of the battery pack 7 is thus prevented in both directions.

An einer Stirnseite der Abdeckhaube 9 ist in diesem Ausführungsbeispiel als Mittel zum Verriegeln der Abdeckhaube 9 in der geschlossenen Stellung ein federnder Schnappverschluß 13 angeordnet. Dieser Schnappverschluß 13 tritt bei geschlossener Abdeckhaube 9 mit einer Begrenzungswand 8 des Batteriefachs in Verbindung. Auf diese Weise wird ein unerwünschtes Öffnen der Abdeckhaube 9 und somit ein unerwünschtes Freigeben der Fixierung des Batterieblocks 7 verhindert.In this exemplary embodiment, a resilient snap lock 13 is arranged on one end face of the cover 9 as a means for locking the cover 9 in the closed position. This snap lock 13 comes into contact with a boundary wall 8 of the battery compartment when the cover 9 is closed. In this way, an undesired opening of the cover 9 and thus an undesired release of the fixing of the battery block 7 is prevented.

In Fig. 3 ist das erfindungsgemäße Batteriefach 7 in Seitenansicht mit geschlossener Abdeckhaube 9 dargestellt. Der Schnappverschluß 13 erstreckt sich durch eine entsprechende Öffnung in der Begrenzungswand 8 und hält die Abdeckhaube 9 in geschlossener Stellung. Im Bereich der Achse 10 befindet sich ein Federelement 14, das auf die Abdeckhaube 9 eine Kraft in Richtung Öffnen ausübt. Es wird damit eine Stellung der Abdeckhaube 9 verhindert, in der diese scheinbar verschlossen ist, der Schnappverschluß 13 aber nicht eingerastet ist. In FIG. 3, the battery compartment 7 to the invention is shown in side view with the cover removed. 9 The snap lock 13 extends through a corresponding opening in the boundary wall 8 and holds the cover 9 in the closed position. In the area of the axis 10 there is a spring element 14 which exerts a force on the cover 9 in the direction of opening. This prevents a position of the cover 9 in which it is apparently closed, but the snap lock 13 is not engaged.

Der schraffiert eingezeichnete Abschnitt des Halteblechs 11 überschneidet sich mit dem Seitenteil 12 des Batterieblocks 7, wodurch erfindungsgemäß eine Bewegung des Batterieblocks 7 in Querrichtung des Flurförderzeugs verhindert wird.The hatched section of the holding plate 11 overlaps with the side part 12 of the battery block 7 , whereby, according to the invention, movement of the battery block 7 in the transverse direction of the industrial truck is prevented.

Fig. 4 zeigt das Batteriefach 7 mit geöffneter Abdeckhaube 9. Bei dieser Stellung der Abdeckhaube kann der Batterieblock 7 frei in Querrichtung des Flurförderzeugs verschoben werden (siehe Fig. 2). Fig. 4 shows the battery compartment 7 with open cover. 9 With this position of the cover, the battery block 7 can be moved freely in the transverse direction of the industrial truck (see FIG. 2).
