Description

Die Erfindung betrifft einen schienengebundenen Transportwagen mit einem auf Schienenfahrwerken abgestützten Maschinenrahmen und einem in Wagenlängsrichtung verlaufenden, oberhalb des Maschinenrahmens angeordneten und bezüglich der Gleisebene unter Bildung eines tiefer gelegenen Aufnahmeendes und eines höher gelegenen Abwurfendes geneigten Bodenförderband, dem zur seitlichen Begrenzung und Bildung eines Speicherraumes parallel zueinander verlaufende Seitenwände zugeordnet sind.The invention relates to a rail-bound transport wagon with a machine frame supported on rail bogies and a floor conveyor belt running in the longitudinal direction of the wagon, arranged above the machine frame and inclined with respect to the track plane with the formation of a lower receiving end and a higher ejecting end, which parallel to one another for lateral limitation and formation of a storage space running sidewalls are assigned.

Ein derartiger Transportwagen ist bereits durch die EP-A-0 368 046 bekannt. Der höher gelegene und in Förderrichtung vordere End- bzw. Abwurfbereich des Bodenförderbandes ist über das Maschinenrahmenende vorragend ausgebildet, so daß dasabwurfseitige Ende des Bodenförderbandes oberhalb eines unteren End- bzw. Aufnahmebereiches eines weiteren Transportwagens zu liegen kommt. Auf diese Weise ist bei einer beliebigen Anzahl von zu einem Zugverband miteinander verbundenen Transportwagen ein durchgehender Transport von Schüttgut mit einer jeweils selbsttätigen Ent- und Beladung möglich. Zur Erzielung einer entsprechenden Schütthöhe für die maximale Speicherung von Schüttgut ist der Höhenunterschied des Bodenförderbandes zwischen Aufnahmeende und Abwurfende im wesentlichen gleich der lichten Wandhöhe der Seitenwände. Bei einem derartigen bekannten Transportwagen treten jedoch im Gleisbogen Probleme bezüglich einer ordnungsgemäßen Materialübergabe vom höher gelegenen Abwurf- auf das tiefer gelegene, vorgeordnete Aufnahmeende auf, da das höher gelegene Abwurfende durch die vorragende Anordnung in einem größeren Ausmaß von der Gleismitte wegbewegt wird.Such a trolley is already known from EP-A-0 368 046. The higher end and in the conveying direction front or discharge area of the floor conveyor belt is designed to protrude beyond the end of the machine frame, so that the discharge-side end of the floor conveyor belt comes to lie above a lower end or reception area of another transport carriage. In this way, with any number of transport wagons connected to each other to form a train, a continuous transport of bulk goods is possible, each with an automatic unloading and loading. In order to achieve a corresponding dumping height for the maximum storage of bulk material, the height difference of the floor conveyor belt between the receiving end and the discharge end is essentially equal to the inside wall height of the side walls. In such a known transport trolley, however, problems arise in the track arch with regard to a proper transfer of material from the higher-lying discharge end to the lower-lying, upstream receiving end, since the higher-lying discharge end is moved to a greater extent away from the middle of the track by the projecting arrangement.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Transportwagens der eingangs beschriebenen Art, mit dem auch in Gleisbögen eine problemlose Schüttgutübergabe auf einen in Transportrichtung vorgeordneten weiteren Transportwagen möglich ist.The object of the present invention is to create a transport carriage of the type described in the introduction, with which it is also possible to transfer bulk goods to a further transport carriage arranged upstream in the direction of transport, even in track bends.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Bodenförderband wenigstens in einem seiner beiden Enden in Bezug auf das in diesem Ende befindliche Schienenfahrweg durch einen Querverschiebeantrieb quer zur Wagenlängsrichtung verschiebbar ausgebildet ist. Durch diese Lösung besteht die Möglichkeit, einen Endbereich des Bodenförderbandes gegenüber der Gleismitte so weit in einer quer zur Wagen- bzw. Gleislängsrichtung verlaufenden Richtung zu verschieben, daß auch in Gleisbögen eine überlappende Anordnung eines Abwurfendes eines ersten Transportwagens über dem Aufnahmeende eines zweiten Transportwagens sichergestellt ist. Dabei ist unter entsprechend weiter Querverschiebung des Bodenförderbandes in vorteilhafter Weise auch in Gleisbögen mit relativ kleinem Radius immer eine problemlose Übergabe des Schüttgutes möglich. Außerdem kann durch die Querverschiebung auch die in Gleisbögen zusätzlich durch die Querneigung des Gleises auftretende Problematik bereinigt werden, wonach das mittig vom höher gelegenen Abwurfende abgeworfene Schüttgut entlang einer vertikalen Fallinie außermittig auf das tiefer gelegene Aufnahmeende auftrifft. Durch eine entsprechende Querverschiebung des Abwurfendes kann nunmehr so lange korrigierend eingegriffen werden, bis das abgeworfene Schüttgut trotz der Querneigung mittig auf das Aufnahmeende auffällt.This object is achieved in that the floor conveyor is at least in one of its two ends with respect to the rail path located in this end by a transverse shift drive transverse to the longitudinal direction of the carriage. With this solution, there is the possibility of shifting an end region of the floor conveyor belt relative to the center of the track so far in a direction running transversely to the longitudinal direction of the wagon or track that an overlapping arrangement of a dropping end of a first transport wagon over the receiving end of a second also in track arches Transport trolley is ensured. With a corresponding further transverse displacement of the floor conveyor belt, an easy transfer of the bulk material is always possible in an advantageous manner even in curved tracks with a relatively small radius. In addition, the transverse displacement also eliminates the problems occurring in the curve of the track due to the transverse inclination of the track, according to which the bulk material dropped in the middle from the higher end of the drop hits the center of the vertical drop line on the lower receiving end. By means of a corresponding transverse displacement of the discharge end, corrective action can now be taken until the discharged bulk material strikes the center of the reception end despite the transverse inclination.

Die Ausgestaltung nach Anspruch 2 hat den Vorteil, daß der höher gelegene und durch seine vorragende Anordnung in Gleisbögen besonders stark außerhalb der Gleismitte zu liegen kommende Abwurfbereich genau über dem unverändert gleismittig liegenden hinteren Aufnahmebereich des Bodenförderbandes zentrierbar ist.The embodiment according to claim 2 has the advantage that the discharge area located higher up and due to its projecting arrangement in track arches is located particularly strongly outside the track center and can be centered exactly above the rear receiving area of the floor conveyor belt, which is unchanged on the track center.

Die Ausgestaltung nach den Ansprüchen 3 und 4 gewährleistet eine problemlose Querverschiebung des Bodenförderbandes unter ständiger sicherer Abstützung am Maschinenrahmen.The design according to claims 3 and 4 ensures problem-free transverse displacement of the floor conveyor belt with constant secure support on the machine frame.

Die in Anspruch 5 gekennzeichnete Variante ergibt eine konstruktiv besonders einfache und stabile Lösung für eine problemlose Querverschiebung des höher gelegenen Abwurfbereiches des Bodenförderbandes.The variant characterized in claim 5 results in a structurally particularly simple and stable solution for a problem-free transverse displacement of the higher discharge area of the floor conveyor belt.

Die Weiterbildung gemäß Anspruch 6 ermöglicht ohne Beeinträchtigung der Verschiebbarkeit eine problemlose Übertragung der durch die Neigung des Bodenförderbandes in dessen Längsrichtung wirksamen Schubkräfte auf den Maschinenrahmen.The development according to claim 6 enables a problem-free transmission of the thrust forces effective due to the inclination of the floor conveyor belt in its longitudinal direction onto the machine frame without impairing the displaceability.

Eine Weiterbildung gemäß Anspruch 7 ermöglicht entweder in Verbindung mit der vorher erwähnten Querverschiebung des Bodenförderbandes relativ zum Maschinenrahmen bzw. auch ohne diese Lösung eine Querverschiebung des Bodenförderbandes mitsamt dem Maschinenrahmen relativ zum Gleis. Damit ist ebenfalls eine von Gleisbögen unabhängige Zentrierung des vorragenden Abwurfbereiches des Bodenförderbandes für eine ungehinderte Übergabe des Schüttgutes auf ein weiteres in Transportrichtung folgendes Bodenförderband möglich.A further development according to claim 7 enables a transverse displacement of the floor conveyor belt together with the machine frame relative to the track either in connection with the previously mentioned transverse displacement of the floor conveyor belt relative to the machine frame or without this solution. A centering of the projecting discharge area of the floor conveyor belt, which is independent of track arches, is thus also possible for an unimpeded transfer of the bulk material to a further floor conveyor belt following in the transport direction.

Mit der in Anspruch 8 und 9 angeführten Schiebewand ist für Überstellfahrten eine ungehinderte, aus der Auslenkung in Gleisbögen resultierende Querbewegung des vorragenden Abwurfbereiches des Bodenförderbandes möglich.With the sliding wall mentioned in claims 8 and 9 there is an unhindered transverse movement of the projecting discharge area resulting from the deflection in track arches for transfer journeys of the floor conveyor belt possible.

Die Ausbildung gemäß Anspruch 10 ermöglicht eine in Abhängigkeit von der gewünschten Schütthöhe stehende optimale Höhenverstellung des Bodenförderbandes. Werden beispielsweise in Serie hintereinander angeordnete Bodenförderbänder lediglich für den Durchtransport von Schüttgut eingesetzt, ist jeweils eine Absenkung der Bodenförderbänder in Bezug auf den Maschinenrahmen möglich. Erst wenn das Schüttgut gespeichert wird, muß lediglich das in Transportrichtung hintere Bodenförderband zur Bildung einer gewünschten Schütthöhe im Übergabebereich angehoben werden.The embodiment according to claim 10 enables an optimal height adjustment of the floor conveyor belt depending on the desired dumping height. If, for example, floor conveyor belts arranged in series are used only for the transport of bulk material, a lowering of the floor conveyor belts with respect to the machine frame is possible in each case. Only when the bulk material is stored, only the rear floor conveyor in the transport direction has to be raised to form a desired bulk height in the transfer area.

Die Ausbildung gemäß Anspruch 11 ermöglicht eine vorteilhafte Höhenverstellung des Bodenförderbandes in seinen höher gelegenen Endbereich, so daß dieses von einer das Lichtraumprofil überschreitenden Arbeitsposition ohne Umrüstarbeiten rasch in eine innerhalb des Lichtraumprofils befindliche Überstellposition verstellbar ist. Durch die Kombination eines Höhen- und Querverschiebeantriebes gemäß Anspruch 12 sind die erwähnten Vorteile bezüglich einer auch in Gleisbögen gesicherten ordnungsgemäßen Übergabe des Schüttgutes und einer auf den Arbeitseinsatz beschränkten Positionierung des Bodenförderbandes außerhalb des Lichtraumprofils erzielbar.The embodiment according to claim 11 enables an advantageous height adjustment of the floor conveyor belt in its higher end region, so that it can be quickly adjusted from a working position that exceeds the clearance profile without conversion work into a transfer position located within the clearance profile. The combination of a vertical and transverse displacement drive according to claim 12, the advantages mentioned can be achieved with respect to a proper transfer of the bulk material, which is also secured in track bends, and a positioning of the floor conveyor belt outside of the clearance profile, which is restricted to work.

Die Ausgestaltung nach den Ansprüchen 13 und 14 ermöglicht bei konstruktiv sehr einfacher Ausbildung des Stützrahmens eine wahlweise Kombination der Höhenverstellung mit der Querverschiebung, wobei in jeder Verstellposition eine sichere Abstützung des Bodenförderbandes am Maschinenrahmen gewährleistet ist.The design according to claims 13 and 14 allows for a structurally very simple design of the support frame, an optional combination of the height adjustment with the transverse displacement, with secure support of the floor conveyor belt on the machine frame being guaranteed in each adjustment position.

Die durch Anspruch 15 gekennzeichnete Abstützung des hinteren, tiefer gelegenen Aufnahmebereiches sichert einerseits eine stabile Lagerung des Bodenförderbandes am Maschinenrahmen und ermöglicht andererseits aber auch eine ungehinderte Höhen- und Querverstellung des höher gelegenen Abwurfbereiches.The support of the rear, lower receiving area characterized by claim 15 ensures on the one hand a stable mounting of the floor conveyor belt on the machine frame and on the other hand also enables unimpeded height and transverse adjustment of the higher discharging area.

The one with the floor conveyor 4 connected support frame 5 is additionally attached to said support 17 so as to be pivotable about an axis 18 extending transversely to the longitudinal direction of the carriage.

Ein im tiefer gelegenen Aufnahmeende 8 des Bodenförderbandes 4 befindlicher Abschnitt jeder Seitenwand 6 ist durch eine parallel zur Seitenwandebene in Wagenlängsrichtung verschiebbare Schiebewand 19 gebildet.A section of each side wall 6 located in the lower receiving end 8 of the floor conveyor belt 4 is formed by a sliding wall 19 which can be displaced parallel to the side wall plane in the longitudinal direction of the carriage.

Das in Fig. 2 ersichtliche Bodenförderband 4 befindet sich in einer durch entsprechende Beaufschlagung des Höhenverstellantriebes 14 abgesenkten Position für Überstellfahrten, bei der insbesondere die oberen Kanten der Seitenwände im Bereich des Abwurfendes 9 innerhalb des vorschriftsmäßigen Lichtraumprofils angeordnet sind. Dabei befinden sich die beiden Schiebewände 19 in einer vorgeschobenen Position, so daß das Abwurfende 9 des nachgeordneten Bodenförderbandes 4 in Gleisbögen eine ungehinderte Auslenkbewegung durchrühren kann.The floor conveyor belt 4 shown in FIG. 2 is in a position for transfer travel which is lowered by appropriately loading the height adjustment drive 14, in which in particular the upper edges of the side walls are arranged in the region of the discharge end 9 within the prescribed clearance profile. The two sliding walls 19 are in an advanced position, so that the discharge end 9 of the downstream floor conveyor belt 4 can perform an unimpeded deflection movement in track curves.

Der in Fig. 3 vergrößert dargestellte Stützrahmen 12 weist zwei parallel zueinander in Wagenlängsrichtung verlaufende und zur Ebene des Maschinenrahmens 3 geneigt angeordnete Stützträger 20 auf, deren tiefer gelegene Enden gelenkig mit dem Stützrahmen 12 und deren höher gelegene Enden mit Spurkranzrollen 21 verbunden sind. Diese sind in der Ebene des Bodenförderbandes 4 im Tragrahmen 5 verschiebbar gelagert. Ein horizontaler, mit dem Höhenverstell- und Querverschiebeantrieb 13,14 sowie mit den beiden Stützträgern 20 verbundener Trägerrahmen 22 ist durch vier Spurkranzrollen 23 auf den beiden quer zur Wagenlängsrichtung verlaufenden Schienen 11 abstützbar.The support frame 12 shown enlarged in FIG. 3 has two support beams 20 which run parallel to one another in the longitudinal direction of the carriage and are inclined to the plane of the machine frame 3, the lower ends of which are articulatedly connected to the support frame 12 and the higher ends of which are connected to flange rollers 21. These are slidably mounted in the plane of the floor conveyor belt 4 in the support frame 5. A horizontal support frame 22, which is connected to the height adjustment and transverse displacement drive 13, 14 and to the two support supports 20, can be supported by four flanged rollers 23 on the two rails 11 running transversely to the longitudinal direction of the carriage.

Wie in Fig. 4 ersichtlich, wurde der Stützrahmen durch Beaufschlagung des mit dem Maschinenrahmen 3 verbundenen Querverschiebeantriebes 13 mitsamt den Höhenverstellantrieben 14, dem Tragrahmen 5 und dem Förderband 4 sowie den Seitenwänden 6 in Bezug auf die Mitte des Maschinenrahmens 3 querverschoben. Diese Querverschiebung kann - in Abhängigkeit vom Radius der Gleiskrümmung - unabhängig von der Höhenverstellung des Bodenförderbandes 4 durch die beiden Höhenverstellantriebe 14 sowie auch unabhängig vom Transport des Schüttgutes durchgeführt werden.As can be seen in FIG. 4, the supporting frame was displaced transversely with respect to the center of the machine frame 3 by acting on the transverse displacement drive 13 connected to the machine frame 3 together with the height adjustment drives 14, the support frame 5 and the conveyor belt 4 and the side walls 6. Depending on the radius of the curvature of the track, this transverse displacement can be carried out independently of the height adjustment of the floor conveyor belt 4 by the two height adjustment drives 14 and also independently of the transport of the bulk material.

Die in Fig. 5 vergrößert dargestellte Schiebewand 19 ist auf Rollen 24 gelagert und mit Hilfe eines Verschiebeantriebes 25 von einer mit vollen Linien dargestellten hinteren Arbeits- in eine mit strichpunktierten Linien dargestellte vordere Überstellposition verschiebbar.The sliding wall 19 shown enlarged in FIG. 5 is mounted on rollers 24 and can be moved by means of a shift drive 25 from a rear working position shown with solid lines to a front transfer position shown with dash-dotted lines.

In der schematischen Darstellung gemäß Fig. 6 ist deutlich ersichtlich, daß das vorkragende Abwurfende 9 des rechten Bodenförderbandes 4 mittig gegenüber dem mit vollen Linien dargestellten Maschinenrahmen 3 versetzt angeordnet ist. Damit ist auch in Gleisbögen (durch eine Gleisachse 26 dargestellt) sichergestellt, daß das Abwurfende 9 über dem vorgeordneten Aufnahmeende 8 eines weiteren Bodenförderbandes 4 zu liegen kommt.6 that the projecting discharge end 9 of the right floor conveyor belt 4 is arranged offset in the center with respect to the machine frame 3 shown with solid lines. This also ensures in track arches (represented by a track axis 26) that the discharge end 9 comes to lie above the upstream receiving end 8 of a further floor conveyor belt 4.

Im folgenden wird die Funktionsweise des erfindungsgemäßen Transportwagens näher beschrieben.
Die Bodenförderbänder 4 eines aus mehreren aneinander gekuppelten Transportwagen 1 gebildeten Verladezuges befinden sich während der Überstellfahrt zur Baustelle in der in Fig. 2 dargestellten, abgesenkten Überstellposition. Die Schiebewände 19 befinden sich jeweils in ihrer vorderen Endposition, so daß die vorragenden Abwurfenden 9 ungehindert in Gleisbögen bewegbar sind. In der Gleisbaustelle wird beispielsweise durch eine Reinigungsmaschine Abraum auf das hinterste Bodenförderband 4 abgeworfen (siehe Fig. 1). Unter Inbetriebnahme der verschiedenen Antriebe 7 für die einzelnen Bodenförderbänder 4 wird das Schüttgut unterjeweiliger Übergabe vom hinteren auf den vorderen Transportwagen 1 zum vordersten Wagen des Verladezuges transportiert. Dabei wird das Bodenförderband 4 des unmittelbar hinter dem vordersten Transportwagen 1 befindlichen Wagens durch Beaufschlagung der Höhenverstellantriebe 14 angehoben, so daß unter Bildung einer entsprechenden Schütthöhe der durch die Seitenwände 6 gebildete Speicherraum des vordersten Transportwagens 1 gefüllt wird. Gleichzeitig mit der Anhebung werden die beiden Schiebewände 19 des das Schüttgut speichernden vordersten Transportwagens 1 in die hintere Endposition verschoben (siehe Fig. 1 bzw. 5).The mode of operation of the trolley according to the invention is described in more detail below.
The floor conveyor belts 4 of a loading train formed from a plurality of coupled transport carriages 1 are in the lowered transfer position shown in FIG. 2 during the transfer journey to the construction site. The sliding walls 19 are each in their front end position, so that the projecting throwing ends 9 can be moved freely in track arches. In the track construction site, overburden is thrown onto the rearmost floor conveyor belt 4, for example by a cleaning machine (see FIG. 1). When the various drives 7 for the individual floor conveyor belts 4 are put into operation, the bulk material is transported from the rear to the front transport carriage 1 to the foremost carriage of the loading train at the respective handover. The floor conveyor belt 4 of the car located immediately behind the foremost transport car 1 is raised by acting on the height adjustment drives 14, so that the storage space formed by the side walls 6 of the foremost transport car 1 is filled to form a corresponding dumping height. Simultaneously with the lifting, the two sliding walls 19 of the foremost transport carriage 1 storing the bulk material are shifted into the rear end position (see FIGS. 1 and 5).

Sobald der Verladezug im Rahmen der kontinuierlichen Arbeitsvorfahrt während des Speicherns in einen Gleisbogen einfährt, wird das höher gelegene und vorragende Abwurfende 9 jedes Transportwagens 1 unter Beaufschlagung des jeweiligen Querverschiebeantriebes 13 so lange querverschoben, bis das jeweilige Abwurfende 9 genau mittig über dem vorgeordneten Aufnahmeende 8 des vorgeordneten Transportwagens 1 liegt. Diese Steuerung kann beispielsweise auch durch entsprechende, an den Schiebewänden 19 montierte und das Abwurfende 9 kontaktierende Endschalter automatisch durchführt werden. Die Beladung wird derart durchgeführt, daß im Bereich der Schiebewände 19 kein Schüttgut gespeichert wird. Zum Auffüllen des zweiten Transportwagens 1 kann das Bodenförderband 4 des ersten Wagens abgesenkt werden, während das nachgeordnete Bodenförderband 4 zur Erzielung einer entsprechenden Schütthöhe angehoben wird. Auf diese Weise werden - beginnend mit dem ersten, vordersten Transportwagen - sämtliche Transportwagen 1 sukzessive aufgefüllt. Abweichend von der beschriebenen Lösung ist es natürlich auch möglich, beispielsweise das hintere, tiefer gelegene Aufnahmeende 8 mit Hilfe eines Querverschiebeantriebes relativ zum Maschinenrahmen querverschiebbar auszubilden, während das vordere, höher gelegene Abwurfende nicht querverschiebbar ist. Damit kann durch eine entsprechende Querverstellung des Aufnahmeendes auch in Gleisbögen eine ungehinderte Materialübergabe vom nachauf den vorgeordneten Transportwagen erfolgen.As soon as the loading train enters a track curve as part of the continuous work priority while storing, the higher and protruding discharge end 9 of each transport carriage 1 is shifted until the respective discharge end 9 is positioned exactly in the middle above the upstream reception end 8 des upstream transport carriage 1. This control can also be carried out automatically, for example, by corresponding limit switches mounted on the sliding walls 19 and contacting the discharge end 9. The loading is carried out in such a way that no bulk material is stored in the area of the sliding walls 19. To fill up the second transport carriage 1, the floor conveyor belt 4 of the first carriage can be lowered, while the downstream floor conveyor belt 4 is raised to achieve a corresponding dumping height. In this way - starting with the first, foremost transport carriage - all transport carriages 1 are successively filled up. Deviating from the solution described, it is of course also possible, for example that to design the rear, lower-lying receiving end 8 with the aid of a transverse displacement drive so that it can be displaced relative to the machine frame, while the front, higher-lying discharge end cannot be displaced transversely. With a corresponding transverse adjustment of the receiving end, unimpeded material transfer from the upstream transport wagon can also take place in track bends.

Ein in Fig. 7 dargestellter Transportwagen mit einem durchgehenden Bodenförderband 27, mit Seitenwänden 28 und einem Maschinenrahmen 29 weist ein gegenüber diesem querverschiebbares Schienenfahrwerk 30 auf. Dieses ist in einer an der Unterseite des Maschinenrahmens 29 befestigten Querführung 31 gelagert und mit einem Querverschiebeantrieb 32 verbunden. Mit einem derartigen Transportwagen kann - zur Sicherstellung einer geordneten Materialübergabe vom vorragenden Abwurf- auf das vorgeordnete Aufnahmeende in Gleisbögen - das Abwurfende mitsamt dem Maschinenrahmen 29 in Bezug auf die Gleismitte querverschoben werden. Zusätzlich besteht auch die Möglichkeit, durch Anordnung entsprechender Höhenverstellantriebe das Bodenförderband 27 relativ zum Maschinenrahmen 29 der Höhe nach zu verstellen.A transport carriage shown in FIG. 7 with a continuous floor conveyor belt 27, with side walls 28 and a machine frame 29 has a rail carriage 30 which can be displaced transversely with respect thereto. This is mounted in a transverse guide 31 fastened to the underside of the machine frame 29 and connected to a transverse displacement drive 32. With a transport trolley of this type - in order to ensure an orderly transfer of material from the projecting drop to the upstream receiving end in track bends - the drop end together with the machine frame 29 can be shifted with respect to the middle of the track. In addition, there is also the possibility of adjusting the height of the floor conveyor belt 27 relative to the machine frame 29 by arranging appropriate height adjustment drives.
