Description

Die Erfindung betrifft einen Flurförderer zum Transportieren von Containern mit mehreren Rädern und mit einer Containeraufnahmeeinrichtung.The invention relates to a floor conveyor for transporting containers with multiple wheels and with a container receiving device.

Das Transportieren der Container mit Flurförderern erfolgt in der Regel zwischen der Verladebrücke eines Schiffsanlegers und einem zur Verladebrücke entfernt gelegenen Containerlager. Dazu im Einsatz befindliche Flurförderer sind insbesondere als Portalstapler ausgebildete Straddle Carrier, mit denen die Container an den Verladebrücken aufgenommen, in die Containerlager hinein transportiert und dort abgestapelt werden können. Da die Containerlager nicht immer unmittelbar neben den Verladebrücken liegen, wird der Einsatz der Portalstapler oftmals maßgeblich vom Horizontaltransport zwischen Verladebrücke und Containerlager geprägt. Für einen überwiegenden Horizontaltransport sind jedoch bekannte Portalstapler, die mit ihren großen Bauhöhen vornehmlich für das Stapeln von Containern konzipiert wurden, weniger geeignet.The transport of containers with floor conveyors is usually between the dock leveler of a jetty and a loading dock remote container warehouse. For this in-use floor conveyor are designed especially as a portal stacker Straddle Carrier, with which the container can be added to the loading bridges, transported into the container storage and can be stacked there. Since the container warehouses are not always located directly next to the loading bridges, the use of the portal stackers is often decisively influenced by the horizontal transport between the loading bridge and the container store. For a predominant horizontal transport, however, known portal stackers, which were designed with their large heights primarily for the stacking of containers, less suitable.

Außerdem befinden sich für einen Horizonaltransport von Zugmaschinen oder dergleichen bewegte Trailer im Einsatz, mit denen die Container unmittelbar unter den Verladebrücken aufgenommen und zum Containerlager gefahren werden. Dort werden die Container von auf Schienen oder Gummirädern fahrenden Portalkränen aufgenommen und in das Containerlager eingestapelt. Die Trailer können die Container jedoch nicht selbsttätig aufnehmen und absetzen, so daß hier nachteilig eine zeitliche Abhängigkeit sowohl an der Verladebrücke als auch im Containerlager entsteht.In addition, there are for a Horizonaltransport of tractors or the like moving trailers in use, with which the containers are taken directly under the loading bridges and driven to the container storage. There, the containers are picked up by gantry cranes moving on rails or rubber wheels and stacked in the container warehouse. However, the trailers can not automatically pick up and set down the containers, so that a disadvantageous time dependence arises both at the loading bridge and in the container storage.

Der Erfindung liegt die Aufgabe zugrunde, einen Flurförderer der eingangs genannten Gattung aufzuzeigen, der für den Horizontaltransport von Containern besonders geeignet ist.The invention has for its object to provide a floor conveyor of the type mentioned, which is particularly suitable for the horizontal transport of containers.

Der erfindungsgemäße Flurförderer zeichnet sich dadurch aus, daß die Containeraufnahmeeinrichtung über ein Hubwerk an den Rädern hubbeweglich abgestützt ist. Die Containeraufnahmeeinrichtung, die auch als Spreader bezeichnet werden kann, ist somit als die Räder miteinander verbindender Fahrrahmen ausgebildet. Zusammen mit den Rädern bildet die als Fahrrahmen ausgebildete Containeraufnahme somit das Fahrwerk aus, wobei seine Räder und sein Fahrrahmen über das Hubwerk miteinander verbunden sind. Durch den Verzicht auf einen üblichen Fahrrahmen mit daran gelagerten Rädern ist ein besonders kompakt bauender Flurförderer geschaffen, dessen Anschaffungs- und Betriebskosten vorteilhaft unter denen der als Straddle Carrier bekannten Flurförderer liegen.The floor conveyor according to the invention is characterized in that the container receiving device is supported by a lifting mechanism on the wheels hubbeweglich. The container receiving device, which can also be referred to as a spreader, is thus formed as the wheels connecting together driving frame. Together with the wheels designed as a driving frame container receptacle thus forms the chassis, with its wheels and its chassis are connected to each other via the hoist. By dispensing with a conventional traveling frame with wheels mounted thereon, a particularly compactly constructed floor conveyor is provided whose acquisition and operating costs are advantageously lower than those of the known as Straddle Carrier floor conveyor.

Nach einer ersten Weiterbildung der Erfindung weist die Containeraufnahmeeinrichtung wenigstens zwei auf dem Hubwerk angeordnete Portale und wenigstens einen die Portale miteinander verbindenden Portalträger auf. Die Portale dienen zum Übergreifen der mit dem Flurförderer zu transportierenden Container. Dazu bestehen die Portalträger jeweils aus zwei Portalstützen und einem die Portalstützen miteinander verbindenden Querträger, wobei die Radaufstandsfläche etwa durch die Abstände der einzelnen Portalstützen zueinander definiert ist. Selbstverständlich liegt es im Rahmen der Erfindung, die Containeraufnahme auch mit mehr als zwei Portalen oder mit mehr als nur einem Portalträger auszubilden.According to a first development of the invention, the container receiving device has at least two portals arranged on the lifting mechanism and at least one portal carrier interconnecting the portals. The portals serve to reach over the container to be transported with the forklift. For this purpose, the gantry girders respectively consist of two gantry supports and a cross girder connecting the gantry supports, the wheel contact surface being approximately defined by the distances between the individual gantry supports. Of course, it is within the scope of the invention to form the container receptacle with more than two portals or with more than one portal carrier.

Nach einer nächsten Weiterbildung der Erfindung weist die Containeraufnahme wenigstens vier in Reihe angeordnete, jeweils mit einem Containerende korrespondierende Anschlagbalken auf. Die Anschlagbalken weisen jeweils zwei Drehschlösser, sogenannte "Twistlocks" auf, die an den Eckbeschlägen der Container automatisch verriegelbar sind. Die Anschlagbalken sind jeweils etwa parallel zu den Portalen ausgerichtet und können einzeln verschiebbar sein. Grundsätzlich kann die Containeraufnahme auch weniger oder mehr als vier Anschlagbalken aufweisen.According to a next development of the invention, the container receiving at least four arranged in series, each with a container end corresponding stop bar. The stop bars each have two rotary locks, so-called "twistlocks", which are automatically lockable on the corner fittings of the container. The Stop bars are each aligned approximately parallel to the portals and can be individually displaceable. In principle, the container receptacle can also have fewer or more than four stop bars.

Vorzugsweise sind mit den Anschlagbalken wenigstens zwei hintereinander angeordnete Containeraufnahmen ausgebildet, die beispielsweise zur Aufnahme von zwei 20-Fuß-Containern geeignet sind. Dazu bilden die vier Anschlagbalken zwei Anschlagbalkenpaare aus, wobei die dasselbe Anschlagbalkenpaar ausbildenden Anschlagbalken zueinander benachbart angeordnet sind.Preferably, at least two successively arranged container receptacles are formed with the stop bars, which are suitable for example for receiving two 20-foot containers. For this purpose, the four stop bars form two stop bar pairs, wherein the same stop bar pair forming stop bars are arranged adjacent to each other.

Außerdem ist mit den beiden äußeren Anschlagbalken gemeinsam eine weitere Containeraufnahme ausgebildet, die beispielsweise zur Aufnahme eines 40-Fuß-Containers geeignet ist. Bei dieser größer ausgebildeten Containeraufnahme sind die in der Reihe zwischen dem äußeren Anschlußbalken angeordneten inneren Anschlußbalken funktionslos. Um ein Hineinstehen der inneren Anschlußbalken in den Aufnahmeraum der durch die äußeren Anschlußbalken ausgebildeten Containeraufnahme zu verhindern, ist gegebenenfalls vorgesehen, daß den inneren Anschlagbalken eine Freistelleinrichtung zugeordnet ist, mit der die inneren Anschlagbalken aus dem Aufnahmeraum herausbewegt werden können. Eine derartige Freistelleinrichtung weist beispielsweise einen die inneren Anschlagbalken nach oben aus ihrer Reihe herausbewegenden Hub- oder Schwenkmechanismus auf.In addition, a further container receptacle is jointly formed with the two outer stop bar, which is suitable for example for receiving a 40-foot container. In this larger trained container receiving the arranged in the row between the outer connecting bar inner connecting bars are inoperative. In order to prevent the inner connecting bars from protruding into the receiving space of the container receptacle formed by the outer connecting bars, it may be provided that the inner stop bars are assigned a free-cutting device with which the inner stop bars can be moved out of the receiving space. Such a cropping device has, for example, a lifting or swiveling mechanism which moves the inner stop bar upwards out of its row.

Nach einer bevorzugten Weiterbildung der Erfindung ist jeder äußere Anschlagbalken an einem Ausziehträger angeordnet, der über eine zur Reihe der Anschlagbalken parallel wirkende Anschlagmittelführung an der Containeraufnahme ausziehbar gehalten ist. Mit derartigen Ausziehträgern sind sämtliche Containeraufnahmen stufenlos auf die Länge der Container einstellbar. Den Ausziehträgern zugeordnete Stellantriebe können dabei sowohl hydraulisch als auch elektrisch ausgeführt sein.According to a preferred embodiment of the invention, each outer stop bar is arranged on a pull-out, which is held extendable over a series of stop bars acting in parallel stop means guide on the container receptacle. With such pull-out all container receptacles are infinitely adjustable to the length of the container. The extractors associated actuators can be carried out both hydraulically and electrically.

Nach einer besonders zweckmäßigen Weiterbildung der Erfindung ist vorgesehen, daß die Portale jeweils wenigstens zwei Anschlagbalken aufweisen und daß die Portale über eine Portalführung längsverschieblich am Portalträger gehalten sind. Mit einer derartigen Ausgestaltung kann jedes Portal eine Containeraufnahme aufweisen, wobei der Abstand zwischen den Containeraufnahmen über die Portalführung verstellbar ist. Mit dieser Funktion können zwei in den Containeraufnahmen aufgenommene Container soweit auseinandergefahren werden, daß sich einander zugekehrte Containertüren vollständig öffnen lassen. Der Portalführung zugeordnete Stellantriebe sind zwischen dem Portalträger und den daran geführten Portalen angeordnet und können ebenfalls sowohl hydraulisch als auch elektrisch ausgeführt sein.According to a particularly advantageous embodiment of the invention, it is provided that the portals each have at least two stop bars and that the portals are held by a portal guide longitudinally displaceable on the portal carrier. With such a configuration, each portal can have a container receptacle, wherein the distance between the container receptacles on the gantry guide is adjustable. With this function, two containers received in the container receptacles can be moved apart so far that can open each other facing container doors completely. The portal guide associated actuators are arranged between the gantry and the portals guided on it and can also be performed both hydraulically and electrically.

Eine besonders belastungsfähige Konstruktion ist dadurch geschaffen, daß die Portalführung und die Anschlagmittelführung teleskopartig ineinanderliegende Führungsflächen aufweisen. Es liegt jedoch im Rahmen der Erfindung, die Portalführung und/oder die Anschlagmittelführung mittels Kulissen-, Schienen- oder Gelenkführungen zu realisieren.A particularly load-bearing construction is provided in that the gantry guide and the stop means guide have telescoping guide surfaces. However, it is within the scope of the invention to realize the portal guide and / or the stop means guide by means of link, rail or joint guides.

Nach einer alternativen Weiterbildung der Erfindung ist vorgesehen, daß die Portale jeweils unbeweglich mit dem Portalträger verbunden sind, und daß jeder innere Anschlagbalken über eine mit der Anschlagmittelführung korrespondierende Parallelführung an der Containeraufnahme gehalten ist. Mit der zusätzlichen Parallelführung ist eine Containeraufnahmeeinrichtung mit zwei Containeraufnahmen geschaffen, bei der der Abstand zwischen den Containeraufnahmen trotz einteiliger Ausbildung der Containeraufnahmeeinrichtung verstellbar bleibt. Somit können auch bei einteiliger Containeraufnahmeeinrichtung zwei in den Containeraufnahmen aufgenommene Container soweit auseinandergefahren werden, daß sich einander zugekehrte Containertüren vollständig öffnen lassen. Der Parallelführung zugeordnete Stellantriebe sind zwischen den inneren Anschlagbalken und der Containeraufnahmeeinrichtung angeordnet und können ebenfalls sowohl hydraulisch als auch elektrisch ausgeführt sein. Das Auseinander- oder Zusammenfahren zweier in den Containeraufnahmen angeordneter Container erfolgt entweder über Stellantriebe der Parallelführung oder über Stellantriebe der Anschlagmittelführung. Die den jeweils nicht benötigten Stellantrieben zugeordneten Anschlagbalken werden über die aufgenommenen Container mitgeschleppt.According to an alternative embodiment of the invention it is provided that the portals are each immovably connected to the gantry, and that each inner stop bar is held on a corresponding with the stop means guide parallel guide on the container receptacle. With the additional parallel guide a container receiving device is provided with two container receptacles, in which the distance between the container receptacles remains adjustable despite one-piece design of the container receiving device. Thus, even in one-piece container receiving device two containers received in the container receptacles can be moved apart so far that can be completely open to each other facing container doors. The parallel guide associated actuators are arranged between the inner stop bar and the container receiving device and can also be performed both hydraulically and electrically. The separation or collapse of two in the container shots arranged container takes place either via actuators of the parallel guide or via actuators of the stop means guide. The respective unavailable actuators associated stop bars are dragged over the recorded container.

Das Hubwerk weist mit Vorteil wenigstens vier, jeweils einem Rad zugeordnete Hubkraftgeber auf. Selbstverständlich kann der erfindungsgemäße Flurförderer auch mehr als vier Räder aufweisen, wobei das Hubwerk dann entsprechend mehreren Rädern zugeordnet ist.The hoist advantageously has at least four hoisting force transmitters each assigned to one wheel. Of course, the floor conveyor according to the invention may also have more than four wheels, the hoist is then assigned according to several wheels.

Die Hubkraftgeber sind über eine Steuerung miteinander verbunden, mit der die Hubkraftgeber wahlweise synchron oder paarweise unabhängig voneinander ansteuerbar sind. Der maximale Hubweg der Hubkraftgeber ist derart bemessen, daß die Container sicher über Flurunebenheiten hinwegtransportiert werden können, ohne dabei am Boden aufzuschlagen. Zum Stapeln der Container ist das Hubwerk des erfindungsgemäßen Flurförderers nicht ausgelegt.The Hubkraftgeber are connected to each other via a controller with which the Hubkraftgeber are either synchronously or in pairs independently controllable. The maximum stroke of the Hubkraftgeber is dimensioned such that the container can be safely transported away over Flurunbenheiten without aufschllagen the ground. For stacking the container, the hoist of the floor conveyor according to the invention is not designed.
