Abstract

A railway freight car (1) for bulk material for operation on a railway line with a stipulated limiting profile (27) which indicates the maximum allowed width and height of the freight car, the maximum allowed width decreasing in an uppermost region of the limiting profile with increasing height above the rail upper edge. The freight car (1) has a storage container (2) which has two side walls (6) and, between these, in the region of the bottom of the storage container, a first conveying device (11) which conveys in the longitudinal direction of the storage container. In an end region of the freight car (1), there is arranged a second conveying device (21) which projects above the car end, can be put out laterally and rises upwards at an angle, the two conveying devices (11, 21) overlapping in the region of the delivery end of the storage container (2) for bulk material transfer from the first to the second conveying device. In order to achieve a great storage capacity and fully to utilise the allowed limiting profile, it is envisaged according to the invention that the storage container (2) runs upwards at an angle, the first conveying device (11) arranged in the region of the bottom of the storage container (2) rising upwards at an angle towards the delivery end (10) of the storage container (2), and that moreover the side walls (6) of the storage container (2) clearly extend into the uppermost region of the limiting profile (27) at least in the region of the delivery end (10) and are inclined inwards at an angle at the top at least in this region of the delivery end (10). <IMAGE>

Description

Die Erfindung betrifft einen Speicherbehälter mit zwei stehenden Seitenwänden und mit einer zwischen den Seitenwänden im Bereich des Bodens des Speicherbehälters angeordneten Fördereinrichtung zur Förderung von Material von einem Beladeendbereich des Speicherbehälters durch diesen hindurch zum gegenüberliegenden Austragendbereich, wobei die Seitenwände oben nach innen eingeschrägt sind.The invention relates to a storage container with two standing side walls and with a conveying device arranged between the side walls in the region of the bottom of the storage container for conveying material from a loading end region of the storage container through this to the opposite discharge end region, the side walls being chamfered inwards at the top.

Solche Speicherbehälter kommen insbesondere auf Schienenfahrzeugen zum Einsatz, um rieselfähiges Gleisbaumaterial, wie Schotter od. dgl. zu speichern bzw. in Längsrichtung des Speicherbehälters weiter zu fördern. Durch die im Boden des Speicherbehälters angeordnete Fördereinrichtung kann eine Speicherung von Material über die gesamte Speicherbehälterlänge vorgenommen werden. Außerdem ist es durch diese Fördereinrichtung möglich, das Material aus dem Speicherbehälter zu entladen bzw. auf einen angeschlossenen weiteren Speicherbehälter eines weiteren Transportwaggons weiterzugeben.Storage tanks of this type are used in particular on rail vehicles in order to store free-flowing track building material, such as ballast or the like, or to further convey them in the longitudinal direction of the storage tank. The conveyor arranged in the bottom of the storage container allows material to be stored over the entire length of the storage container. In addition, this conveying device makes it possible to unload the material from the storage container or to pass it on to a connected further storage container of a further transport wagon.

Es sind bereits Speicherbehälter bekannt, bei denen die Seitenwände praktisch über die gesamte Speicherbehälterlänge immer im gleichen Ausmaß nach oben innen eingeschrägt sind. Durch eine solche Einschrägung der Seitenwände über die gesamte Speicherbehälterlänge geht einiges an für die Speicherung von Material zur Verfügung stehendem Volumen verloren.Storage containers are already known in which the side walls are always chamfered inward to the same extent practically over the entire length of the storage container. Such a bevelling of the side walls over the entire length of the storage container means that some of the volume available for storing material is lost.

Aufgabe der Erfindung ist es, einen insbesondere für den Einsatz auf Schienenfahrzeugen geeigneten Speicherbehälter zu schaffen, der eine hohe Speicherkapazität aufweist und bei dem das gespeicherte Material ohne die Gefahr einer Verklemmung in Längsrichtung des Speicherbehälters durch die am Speicherbehälterboden angeordnete Fördereinrichtung gefördert werden kann.The object of the invention is to provide a storage container which is particularly suitable for use on rail vehicles and which has a high storage capacity and in which the stored material has no risk of jamming can be conveyed in the longitudinal direction of the storage container by the conveyor arranged on the storage container bottom.

Dies wird erfindungsgemäß dadurch erreicht, daß die wenigstens im Bereich des Beladeendes über die ganze Seitenwandhöhe im wesentlichen vertikale bzw. nach oben trichterförmig erweiterten Seitenwände zumindest im Austragendbereich gegen das Austragende hin oben zunehmend nach innen eingeschrägt sind und daß im Bereich der eingeschrägten Seitenwandbereiche an der Innenwand jeweils eine Innenwandfläche ausgebildet ist, die zumindest in ihrem - in Förderrichtung der Fördereinrichtung gesehen - vorderen Bereich gegenüber der Förderrichtung der Fördereinrichtung schräg nach oben ansteigt und zumindest in einem - in Förderrichtung gesehen - dahinterliegenden Bereich quer zur Förderrichtung schräg nach innen abfällt.This is achieved according to the invention in that the side walls, which are substantially vertical or funnel-shaped at the top in the area of the loading end over the entire side wall height, are increasingly beveled inward at least in the discharge end area towards the discharge end and in the area of the beveled side wall areas on the inner wall In each case, an inner wall surface is formed which, at least in its front area, as seen in the conveying direction of the conveying device, rises obliquely upward with respect to the conveying direction of the conveying device, and at least in an area, seen in the conveying direction, falls obliquely inward transversely to the conveying direction.

Der erfindungsgemäße Speicherbehälter läßt sich vorteilhaft auf einem Schienenfahrzeug anordnen, wobei der Speicherbehälter gegen das Austragende hin schräg nach oben verläuft und das Austragende über die Puffer des Schienenfahrzeuges auskragt. Damit ist eine Materialübergabe an ein gleichartiges Schienenfahrzeug (Transportwaggon) möglich. Durch mehrere aneinander gekuppelte Schienenfahrzeuge dieser Art kann man einen Transportzug hoher Bunkerkapazität erzielen. Beim erfindungsgemäßen Speicherbehälter sind zumindest im Bereich des Beladeendes im wesentlichen über die ganze Seitenwandhöhe reichende vertikale bzw. nach oben trichterförmig erweiterte Innenwandflächen vorgesehen. Durch die vertikalen, oben nicht eingeschrägten Seitenwandbereiche erzielt man eine höhere Bunkerkapazität in diesem Bereich. Außerdem wird damit das Einladen von Material, beispielsweise durch Übergabe von einem gleichartigen Speicherbehälter, erleichtert. Beim erfindungsgemäßen Speicherbehälter sind die Seitenwände erst gegen das Austragende hin oben zunehmend nach innen eingeschrägt. Diese Einschrägung der Seitenwände ist bei schräg nach oben auf Schienenfahrzeugen angeordneten Speicherbehältern nötig,um innerhalb des von den Bahnen vorgeschriebenen Lichtraumprofiles zu bleiben. Eine solche Einschrägung gegen das Austragende kann jedoch auch bei nicht auf Schienenfahrzeugen eingesetzten Speicherbehältern zur besseren Lenkung und Führung des Materialstromes vor der Ausgabe aus den Speicherbehältern benutzt werden. Bei einem Einsatz auf Schienenfahrzeugen erlaubt die zunehmende Einschrägung der Seitenwände gegen das Austragende hin eine hohe Anhebung des Austragendes gegenüber den Schienen ohne die gesamte Bunkerkapazität des Speicherbehälters wesentlich zu verringern. Die hohe Austraghöhe erlaubt eine optimale Materialübergabe an einen angeschlossenen gleichartigen Transportwaggon, wobei am Beladeende desselben eine bis etwa zur lichten Höhe des Speicherbehälters reichende Materialeinfüllung möglich ist.The storage container according to the invention can advantageously be arranged on a rail vehicle, the storage container running obliquely upwards towards the discharge end and the discharge end projecting over the buffers of the rail vehicle. This enables material to be transferred to a similar rail vehicle (transport wagon). A transport train of high bunker capacity can be achieved by several coupled rail vehicles of this type. In the storage container according to the invention, at least in the region of the loading end, vertical or funnel-shaped inner wall surfaces extending essentially over the entire side wall height are provided. The vertical side wall areas, which are not chamfered at the top, result in a higher bunker capacity in this area. It also makes it easier to load material, for example by transferring it from a similar storage container. In the storage container according to the invention the side walls are only gradually tapered inwards towards the discharge end. This beveling of the side walls is necessary in the case of storage containers arranged obliquely upwards on rail vehicles in order to remain within the clearance profile prescribed by the railways. Such an inclination towards the discharge end can, however, also be used in the case of storage containers which are not used on rail vehicles for better steering and guiding of the material flow before the output from the storage containers. When used on rail vehicles, the increasing inclination of the side walls towards the discharge end allows the discharge end to be raised high compared to the rails without significantly reducing the overall bunker capacity of the storage container. The high discharge height allows optimal material transfer to a connected transport wagon of the same type, whereby at the loading end of the same it is possible to fill the material up to the clear height of the storage container.

Durch die anfänglich vertikalen Innenwandflächen, die dann gegen das Austragende hin zunehmend nach innen eingeschrägt sind, verringert sich die Querschnittsfläche im Speicherbehälter gegen das Austragende hin. Ohne zusätzliche Maßnahmen besteht dabei die Gefahr, daß insbesondere bei lokal sehr hohen Materialanhäufungen innerhalb des Speicherbehälters Zwänge beim Einlauf des Materials in die Profileinschränkung entstehen, die zu einem Verkeilen von Material, beispielsweise Schotterstücken, führen können. Um dies zu vermeiden, ist beim erfindungsgemäßen Speicherbehälter im Bereich der eingeschrägten Seitenwandbereiche an der Innenwand jeweils eine zunächst gegenüber der Förderrichtung schräg nach oben ansteigende und zugleich bzw. anschließend nach innen abfallende Innenwandfläche zur Führung des Schotters ausgebildet. Diese Innenwandfläche kann auch aus mehreren Teilflächen bestehen, wobei der - in Förderrichtung gesehen - vorderen Teilfläche primär die Aufgabe zukommt, im Bereich der Innenwandflächen geführtes Material oberhalb einer bestimmten Höhe zunächst anzuheben. Über eine schräg nach innen abfallende weitere Teilfläche kann dieses Material dann ohne Ausübung von Zwängen auf das im mittleren Bereich des Speicherbehälters geförderte Material hinab fallen. Grundsätzlich kann diese Hebe- und Leitfläche für den Schotter od. dgl. auf der linken und rechten Seitenwand jeweils auch aus einer gekrümmten Fläche bestehen, die die seitlichen Materialbereiche oberhalb einer bestimmten Höhe zunächst anhebt und dann von oben dem mittleren Bereich des Speicherbehälters zuführt.Due to the initially vertical inner wall surfaces, which are then increasingly tapered inwards towards the discharge end, the cross-sectional area in the storage container decreases towards the discharge end. Without additional measures, there is a risk that especially when there are very high accumulations of material within the storage container, constraints arise when the material enters the profile restriction, which can lead to wedging of material, for example pieces of ballast. In order to avoid this, in the storage container according to the invention, an inner wall surface for guiding the ballast is formed on the inner wall in the region of the beveled side wall regions, initially rising at an angle with respect to the conveying direction and at the same time or subsequently falling inwards. This inner wall surface can also consist of several partial surfaces, the front one - seen in the conveying direction Partial area primarily has the task of first lifting material in the area of the inner wall surfaces above a certain height. This material can then drop down onto the material conveyed in the central region of the storage container without any constraints via a further partial surface sloping inwards. Basically, this lifting and guiding surface for the ballast or the like on the left and right side wall can each consist of a curved surface which first lifts the lateral material areas above a certain height and then feeds them from above to the central area of the storage container.

Eine Variante der Erfindung geht aus von einem Speicherbehälter mit zwei stehenden Seitenwänden und mit einer zwischen den Seitenwänden im Bereich des Bodens des Speicherbehälters angeordneten Fördereinrichtung zur Förderung von Material von einem Beladeendbereich des Speicherbehälters durch diesen hindurch zum gegenüberliegenden Austragendbereich, wobei die Seitenwände oberhalb einer im wesentlichen vertikalen Innenwandfläche eine oben schräg nach innen geneigte, im wesentlichen ebene Innenwandfläche aufweisen und wobei sich die vertikale und die schräge Innenwandfläche jeder Seitenwand in einer zur Förderrichtung der Fördereinrichtung bzw. zur Längsrichtung des Speicherbehälters im wesentlichen parallelen Schnittgeraden schneiden.A variant of the invention is based on a storage container with two standing side walls and with a conveying device arranged between the side walls in the region of the bottom of the storage container for conveying material from a loading end region of the storage container through this to the opposite discharge end region, the side walls above essentially one vertical inner wall surface have a substantially flat inner wall surface which is inclined inwardly at an upward angle, and the vertical and the inclined inner wall surface of each side wall intersect in a straight line of intersection which is essentially parallel to the conveying direction of the conveying device or to the longitudinal direction of the storage container.

Erfindungsgemäß ist ein solcher Speicherbehälter dadurch gekennzeichnet, daß die in einer Normalebene auf die Längsrichtung des Speicherbehälters gemessene Breite jeder schrägen Innenwandfläche ausgehend vom Austragende entgegen der Förderrichtung abnimmt bis die obere Begrenzungslinie der schrägen Innenwandfläche in einem Schnittpunktsbereich im wesentlichen auf die Schnittgerade zwischen schräger und vertikaler Innenwandfläche trifft, daß sich die vertikalen Innenwandflächen zumindest in einem - in Förderrichtung gesehen - vor dem jeweiligen Schnittpunktsbereich liegenden Bereich über die gesamte Seitenwandhöhe erstrecken, und daß an die gesamte obere Begrenzungslinie jeder schrägen Innenwandfläche jeweils eine weitere Innenwandfläche anschließt, die von der oberen Begrenzungslinie nach außen ansteigt, in einem an den Schnittpunktsbereich anschließenden Bereich stetig an die vertikale Innenwandfläche anschließt und gegen das Austragende hin in ihrer Breite - gemessen in einer Normalebene auf die Förderrichtung - abnimmt, vorzugsweise bis auf Null am Austragende.According to the invention, such a storage container is characterized in that the width of each inclined inner wall surface, measured in a normal plane to the longitudinal direction of the storage container, decreases from the discharge end against the conveying direction until the upper boundary line of the inclined inner wall surface in a region of intersection essentially corresponds to the line of intersection between the inclined and vertical inner wall surface hits that the vertical Inner wall surfaces extend at least in one area - in the conveying direction - in front of the respective intersection area over the entire side wall height, and that the entire upper boundary line of each inclined inner wall surface is followed by a further inner wall surface which rises from the upper boundary line to the outside The area adjoining the intersection point is continuously connected to the vertical inner wall surface and decreases in width towards the discharge end - measured in a normal plane on the conveying direction - preferably down to zero at the discharge end.

Bei dieser Variante des erfindungsgemäßen Speicherbehälters ist die durch eine Parallele zur Förderrichtung und die Einschrägung am Austragende aufgespannte ebene Innenwandfläche entgegen der Förderrichtung nach vorne gezogen, wobei die Breite dieser ebenen Innenwandfläche entgegen der Förderrichtung laufend bis praktisch auf Null abnimmt. An die obere Begrenzungslinie jeder dieser schrägen nach vorne spitz zulaufenden Innenwandflächen schließt oben eine weitere Innenwandfläche stetig an, die von der oberen Begrenzungslinie nach außen ansteigt und in einem vorderen Bereich stetig an die vertikale Innenwandfläche anschließt, welche in diesem Bereich vorzugsweise über die gesamte Behälterhöhe reicht. Gegen das Austragende hin nimmt die oberhalb der Begrenzungslinie anschließende Innenwandfläche in ihrer Breite bis vorzugsweise auf Null am Austragende ab. Dies erlaubt unter anderem eine entsprechende Einschrägung der Außenflächen der Seitenwände, um beispielsweise bei einem Einsatz des Speicherbehälters auf Schienenfahrzeugen innerhalb des vorgeschriebenen oben eingeschrägten Lichtraumprofiles zu bleiben.In this variant of the storage container according to the invention, the flat inner wall surface spanned by a parallel to the conveying direction and the bevel at the discharge end is drawn forward against the conveying direction, the width of this flat inner wall surface continuously decreasing counter to the conveying direction to practically zero. At the upper boundary line of each of these obliquely tapering inner wall surfaces, a further inner wall surface continuously adjoins at the top, which rises outwards from the upper boundary line and in a front region continuously adjoins the vertical inner wall surface, which in this region preferably extends over the entire container height . Towards the discharge end, the width of the inner wall surface adjoining the boundary line decreases to preferably zero at the discharge end. This allows, among other things, a corresponding beveling of the outer surfaces of the side walls, in order, for example, to remain within the prescribed clearance space profile as indicated above when the storage container is used on rail vehicles.

Bei der zuletzt beschriebenen Variante des erfindungsgemäßen Speicherbehälters läuft das Material, das sich von vorne herein innerhalb des eingeschränkten Innenwandprofils am Austragende befindet praktisch ungestört über die Längsrichtung des Speicherbehälters. Jenes Material, das sich zunächst im Randbereich oberhalb einer bestimmten Höhe der vertikalen Seitenwände befindet und gegen das Austragende hin auf die Einschrägung der Seitenwände treffen würde, wird jeweils von der weiteren Innenwandfläche oberhalb der nach vorne gezogenen schrägen Innenwandfläche zunächst nach oben angehoben und fällt dann entlang der nach außen ansteigenden (also nach innen abfallenden) Innenwandfläche ohne Zwang und ohne die Gefahr eines Verkeilen auf das im mittleren Bereich geförderte Haufwerk von oben drauf. Die genannte weitere Innenwandfläche oberhalb der schrägen nach vorne gezogenen Innenwandfläche kann auch aus zwei stetig ineinander übergehenden Teilflächen bestehen, die sich beispielsweise durch verschweißte Bleche einfach ausbilden lassen. In einem solchen Fall kommt der - in Förderrichtung gesehen - vorderen Teilfläche vornehmlich die Aufgabe zu, die seitlichen Materialbereiche anzuheben während der daran anschließenden zweiten ebenen Teilfläche, die schräg nach innen abfällt, vornehmlich die Aufgabe zukommt, das angehobene Material dem mittleren Materialbereich von oben zuzuführen.In the variant of the storage container according to the invention described last, the material that is located from the front within the restricted inner wall profile at the discharge end runs practically undisturbed over the longitudinal direction of the storage container. The material that is initially in the edge area above a certain height of the vertical side walls and would hit the bevel of the side walls towards the discharge end is first lifted upward from the further inner wall surface above the inclined inner wall surface and then falls along the inside wall surface that rises outwards (that is, falls inwards) without constraint and without the risk of wedging onto the bulk material conveyed in the central area from above. Said further inner wall surface above the inclined inner wall surface drawn forward can also consist of two continuously merging partial surfaces, which can be easily formed, for example, by welded metal sheets. In such a case, the front partial surface - as seen in the conveying direction - primarily has the task of lifting the lateral material areas, while the subsequent second flat partial surface, which slopes downwards inward, primarily has the task of feeding the raised material to the central material region from above .

Weitere Vorteile und Einzelheiten der Erfindung werden in der nachstehenden Figurenbeschreibung näher erläutert.Further advantages and details of the invention are explained in more detail in the following description of the figures.

Der in Fig. 1 in einem zentralen, schematischen Längsschnitt dargestellte Speicherbehälter 1 ist auf einem Schienenfahrzeug 2 angeordnet und bildet zusammen mit diesem einen Transportwaggon, der beispielsweise zur Speicherung bzw. Weitergabe von Schotter od. dgl. geeignet ist. Der Transportwaggon weist einen Rahmen 3 und zwei Drehgestelle 4 auf, deren Räder auf Schienen 5 laufen. Der Speicherbehälter ist mit zwei stehenden Seitenwänden 6 versehen, deren vertikale Innenwandflächen 7 im wesentlichen über die gesamte Speicherbehälterlänge zueinander parallel verlaufen und damit bei der Förderung von Material (nicht dargestellt) in Längsrichtung des Speicherbehälters bzw. in Förderrichtung 8 keinerlei Anlaß zu einer Materialverklemmung od. dgl. geben. Zur Förderung des nicht dargestellten Materials vom vorderen Beladeendbereich 9 durch den Speicherbehälter 1 hindurch zum gegenüberliegenden hinteren Austragendbereich 10 ist im Bereich des Bodens des Speicherbehälters 1 eine, im wesentlichen über die gesamte lichte Breite des Speicherbehälters reichende Fördereinrichtung 11 vorgesehen. Beim gezeigten Ausführungsbeispiel besteht die Fördereinrichtung im wesentlichen aus einem endlos umlaufenden Förderband 11, das um eine Spanntrommel 12 und um eine Antriebstrommel 13 geführt ist und im mittleren Bereich des Speicherbehälters etwas nach unten abgesenkt ist, um die Speicherkapazität weiter zu erhöhen. Um ein Verkeilen von Material zwischen den Seitenwänden 6 und dem Obertrum des Förderbandes 11 zu vermeiden, sind schräge Abweisbleche 14 vorgesehen (vgl. auch Fig. 7a). Die Fördereinrichtung 11 fördert das Material vom Beladeendbereich 9 im wesentlichen in Förderrichtung 8 zum Austragendbereich 10, wobei das durch die Antriebstrommel 13 gebildete Austragende über die Puffer 15 auskragt und oberhalb des Beladeendbereiches 9′ eines weiteren Transportwaggons (in Fig. 1 nur teilweise dargestellt) angeordnet ist. Die Übergabehöhe vom Austragendbereich des einen Waggons auf den Beladeendbereich 9′ des anderen Waggons entspricht im wesentlichen der lichten Wandhöhe, womit eine optimale Ausnutzung der Speicherkapazität der Transportwaggons gegeben ist, da das Material eben bei der Übergabe an den weiteren angeschlossenen Transportwaggon bis etwa zur lichten Wandhöhe angefüllt werden kann. Der in Fig. 1 nur teilweise dargestellte Transportwaggon ist im wesentlichen gleich aufgebaut wie der in voller Länge dargestellte Transportwaggon, weshalb für gleiche bzw. äquivalente Teile gleiche Bezugsziffern, jedoch mit einem Strich versehen verwendet sind.The storage container 1 shown in a central, schematic longitudinal section in FIG. 1 is arranged on a rail vehicle 2 and, together with it, forms a transport wagon which is suitable, for example, for storing or transferring crushed stone or the like. The transport wagon has a frame 3 and two bogies 4, the wheels of which run on rails 5. The storage container is provided with two standing side walls 6, the vertical inner wall surfaces 7 of which run essentially parallel to one another over the entire length of the storage container and thus do not give rise to any material jamming in the longitudinal direction of the storage container or in the conveying direction 8 when material is being conveyed (not shown). the like. To convey the material, not shown, from the front loading end area 9 through the storage container 1 to the opposite one rear discharge area 10 is provided in the region of the bottom of the storage container 1, a conveying device 11 which extends essentially over the entire clear width of the storage container. In the embodiment shown, the conveyor essentially consists of an endlessly rotating conveyor belt 11, which is guided around a tension drum 12 and a drive drum 13 and is lowered somewhat in the middle region of the storage container in order to further increase the storage capacity. In order to avoid wedging of material between the side walls 6 and the upper run of the conveyor belt 11, inclined deflector plates 14 are provided (cf. also FIG. 7a). The conveying device 11 conveys the material from the loading end area 9 essentially in the conveying direction 8 to the discharge end area 10, the discharge end formed by the drive drum 13 protruding over the buffers 15 and arranged above the loading end area 9 'of a further transport wagon (only partially shown in FIG. 1) is. The transfer height from the discharge area of one wagon to the loading end area 9 'of the other wagon essentially corresponds to the clear wall height, which gives optimal use of the storage capacity of the transport wagons, since the material is transferred to the other connected transport wagon up to the clear wall height can be filled. The transport wagon shown only partially in Fig. 1 is constructed essentially the same as the transport wagon shown in full length, which is why the same reference numerals but with a dash are used for the same or equivalent parts.

Damit bei der Übergabe von Material an den Folgewaggon auch in Kurven kein Material daneben geht bzw. um allgemein den aus dem Speicherbehälter austretenden Materialstrom seitlich zu begrenzen, kann vorgesehen sein,daß die lichte Breite des Speicherbehälters 1 im Austragendbereich 10 vorzugsweise durch Leitbleche 16 begrenzt ist, wobei die Leitbleche 16 oberhalb des Förderbandes 11 angeordnet sind und günstigerweise über das austragseitige Ende 13 der Fördereinrichtung (Förderband) auskragen. Die Lage der Leitbleche 16 ist auch in Fig. 5 in einer Draufsicht ersichtlich.So that when material is transferred to the following wagon, no material goes wrong or in general around the To limit the material flow emerging from the storage container laterally, it can be provided that the clear width of the storage container 1 in the discharge end area 10 is preferably limited by guide plates 16, the guide plates 16 being arranged above the conveyor belt 11 and advantageously via the discharge-side end 13 of the conveyor device ( Cantilever). The position of the guide plates 16 can also be seen in a top view in FIG. 5.

Um bei reduziertem Materialaufwand und geringem Gewicht des Speicherbehälters eine optimale Ausnutzung der Speicherkapazität zu haben, ist es günstig, wenn die Oberkanten 6a der Seitenwände 6 zumindest über einen Großteil der Speicherbehälterlänge in einer gemeinsamen gedachten Ebene liegen, die zur Förderrichtung 8 des Förderbandes 11 im wesentlichen parallel angeordnet ist. Die linke und die rechte Seitenwand des Speicherbehälters sind günstigerweise spiegelsymmetrisch zur Längsmittelebene des Speicherbehälters ausgebildet. Der Speicherbehälter ist zumindest beim Beladeendbereich 9 oben offen und kann in diesem Bereich gegebenenfalls auch geringfügig nach oben trichterförmig erweiterte Seitenwände aufweisen. Günstig ist es weiters, wenn der Speicherbehälter nach oben zwischen den beiden Seitenwänden 6 über die gesamte Speicherbehälterlänge offen ist.In order to have an optimal utilization of the storage capacity with reduced material expenditure and low weight of the storage container, it is favorable if the upper edges 6a of the side walls 6 lie at least over a large part of the storage container length in a common imaginary plane, which essentially corresponds to the conveying direction 8 of the conveyor belt 11 is arranged in parallel. The left and right side walls of the storage container are expediently mirror-symmetrical to the longitudinal center plane of the storage container. The storage container is open at the top, at least in the loading end region 9, and in this region can also optionally have funnel-shaped side walls. It is also expedient if the storage container is open at the top between the two side walls 6 over the entire length of the storage container.

Erfindungsgemäß sind die im Bereich des Beladeendes 9 im wesentlichen vertikalen Seitenwände 6 zumindest im Austragendbereich 10 gegen das Austragende hin oben zunehmend nach innen eingeschrägt. Die eingeschrägten Außenflächen 6b der Seitenwände sind in Fig. 2 ersichtlich, in der allerdings weitere erfindungswesentliche Merkmale, insbesondere die Ausgestaltung an den Innenwänden der Seitenwände 6 nicht näher dargestellt sind. Durch die zunehmende Einschrägung der Seitenwände gegen das Austragende hin erreicht man, beispielsweise bei einem Einsatz des erfindungsgemäßen Speicherbehälters auf Schienenfahrzeugen, wo der Speicherbehälter 1 unter einem Winkel α relativ zu den Schienen schräg nach oben ansteigt, dennoch daß sich der Speicherbehälter innerhalb des vorgegebenen, im oberen Bereich eingeschränkten Lichtraumprofiles befindet. Die Lage der Einschrägungen der Seitenwände ist im allgemeinen an äußere Erfordernisse, wie beispielsweise das zur Verfügung stehende Lichtraumprofil angepaßt. Durch eine entsprechende Wahl der Einschrägung läßt sich auch der am Austragende ausgegebene Materialstrom beeinflussen. Je nach Ausmaß der Einschrägung 17 am Austragsende des Speicherbehälters 1 wird die Einschrägung weiter vorne bzw. weiter hinten am Speicherbehälter beginnen. Insbesondere für einen in der dargestellten Weise auf einem Schienenfahrzeug angeordneten Speicherbehälter ist es im Hinblick auf eine hohe Bunkerkapazität unter Ausnutzung des zur Verfügung stehenden Lichtraumprofiles günstig, wenn die oben nach innen eingeschrägten Seitenwandbereiche 6b jeweils in einem mittleren Bereich des Speicherbehälters 1 beginnen und sich von dort nach hinten bis zum Austragende erstrecken.According to the invention, the substantially vertical side walls 6 in the area of the loading end 9 are at least in the discharge area 10 towards the discharge end increasingly beveled inwards. The bevelled outer surfaces 6b of the side walls can be seen in FIG. 2, in which, however, further features essential to the invention, in particular, the design on the inner walls of the side walls 6 are not shown in detail. Due to the increasing inclination of the side walls towards the discharge end, for example when using the storage container according to the invention on rail vehicles, where the storage container 1 rises obliquely upwards at an angle α relative to the rails, the storage container nevertheless increases within the predetermined, in located in the upper area of the restricted clearance profile. The position of the bevels of the side walls is generally adapted to external requirements, such as the available clearance profile. The material flow output at the discharge end can also be influenced by an appropriate choice of the bevel. Depending on the extent of the bevel 17 at the discharge end of the storage container 1, the bevel will begin further forward or further back on the storage container. In particular for a storage container arranged in the manner shown on a rail vehicle, it is advantageous with regard to a high bunker capacity, making use of the available clearance profile, if the side wall regions 6b which are inclined inwards at the top each begin in a central region of the storage container 1 and move away from there extend back to the discharge end.

Beim einem Speicherbehälter, der im wesentlichen wie der in Fig. 2 gezeigte ausgebildet ist, würde es durch die zunehmende Einschränkung der Querschnittsfläche gegen das Austrittsende hin zu unerwünschten Zwängen in der Führung des Materials (beispielsweise Schotter) kommen, wenn dieses Material in die Profileinschränkung bei einer Förderung in der Förderrichtung 8 einläuft. Um dies zu vermeiden, ist erfindungsgemäß im Bereich der eingeschrägten Seitenwandbereiche 6b an der Innenwand jeweils eine Innenwandfläche 18a, 18b ausgebildet, die zumindest in ihrem - in Förderrichtung 8 des Förderbandes 11 gesehen - vorderen Bereich 18a gegenüber der Förderrichtung 8 schräg nach oben ansteigt, um zumindest in einem dahinterliegenden Bereich 18b quer zur Förderrichtung 8 schräg nach innen zur Speicherbehältermitte hin abzufallen. Durch solche Innenwandflächen 18a, 18b wird das durch die Fördereinrichtung 11 oberhalb einer bestimmten Materialhöhe geförderte Material anstelle eines Zwangs in die Profileinschränkung durch den vorderen Bereich 18a zunächst angehoben und kann dann ohne Ausübung von Zwängen durch den dahinterliegenden Bereich, der quer zur Förderrichtung schräg nach innen abfällt, dem im Bereich der Speicherbehältermitte geführten Material von oben zugeführt werden. Die genaue Lage der Innenwandflächen 18a, 18b wird im folgenden noch näher beschrieben. Zunächst wird aber noch darauf hingeweisen, daß unter der Förderrichtung 8 der Fördereinrichtung 11 jene mittlere Hauptförderrichtung gemeint ist, in der das Material mittels der Fördereinrichtung 11 durch den Speicherbehälter hindurch gefördert wird. Die Fördereinrichtung fällt also mit der Längsrichtung des Speicherbehälters zusammen, enthält aber gegenüber dieser Längsrichtung des Speicherbehälters noch eine Orientierung, nämlich vom Beladeendbereich 9 zum Austragendbereich 10 hin. Weiters wird bemerkt, daß vom Bereich der eingeschrägten Seitenwandbereiche auch jener Bereich umfaßt ist, der direkt vor der eigentlichen Einschrägung der Außenflächen 6b der Seitenwände 6 (Fig. 2) liegt. Im allgemeinen wird es sogar günstig sein, wenn der vordere "Hebebereich" 18a der erfindungsgemäßen Innenwandfläche vor der eigentlichen Einschrägung (Punkt D in Fig. 3) liegt, wie dies beispielsweise in Fig. 1 gezeigt ist, oder zumindest dort beginnt.In the case of a storage container which is essentially designed like that shown in FIG. 2, the increasing restriction of the cross-sectional area towards the outlet end would lead to undesirable constraints in the guidance of the material (for example ballast) if this material were to restrict the profile funding in the direction of funding 8 arrives. To avoid this, the invention is in the area of the beveled side wall areas 6b, an inner wall surface 18a, 18b is formed on the inner wall in each case, which at least in its front region 18a - as seen in the conveying direction 8 of the conveyor belt 11 - rises obliquely upwards with respect to the conveying direction 8, at least in a region 18b behind it obliquely to the conveying direction 8 to fall down towards the center of the storage tank. By means of such inner wall surfaces 18a, 18b, the material conveyed by the conveying device 11 above a certain material height is first raised instead of being forced into the profile restriction by the front region 18a and can then be exerted through the region behind it, which obliquely inwards transversely to the conveying direction drops, the material guided in the area of the middle of the storage container are fed from above. The exact position of the inner wall surfaces 18a, 18b is described in more detail below. First of all, however, it is pointed out that the conveying direction 8 of the conveying device 11 means that central main conveying direction in which the material is conveyed through the storage container by means of the conveying device 11. The conveying device thus coincides with the longitudinal direction of the storage container, but also contains an orientation with respect to this longitudinal direction of the storage container, namely from the loading end region 9 to the discharge end region 10. It is further noted that the area of the beveled side wall areas also includes that area which lies directly before the actual beveling of the outer surfaces 6b of the side walls 6 (FIG. 2). In general, it will even be advantageous if the front “lifting area” 18a of the inner wall surface according to the invention lies in front of the actual bevel (point D in FIG. 3), as is shown for example in FIG. 1, or at least begins there.

Die Lage der erfindungsgemäßen Innenwandflachen wird nun anhand der Fig. 2 bis 4 näher erläutert, wobei die Fig. 2 und 3 lediglich zur besseren Darstellung dienen und noch nicht die erfindungsgemäße Ausbildung der Innenwandflächen zeigen. In den Fig. 3 und 4 ist außerdem nur die linke Innenwand perspektivisch dargestellt. Die rechte Innenwand ist bezüglich der Längsmittelebene des Speicherbehälters symmetrisch dazu ausgebildet. Um nun die erfindungsgemäßen Innenwandflächen zu erhalten, wird zunächst die am Austragende wegen des vorgeschriebenen Lichtraumprofiles notwendige Profileinschränkung E,F (Bezugsziffer 17) parallel zu sich selbst entgegen der Förderrichtung 8 bis zu den Punkten E˝,F˝, weiter wie die eigentliche äußere Profileinschränkung (beginnend am Punkt D) nach vorne gezogen. Dabei entsteht die in Fig. 3 ersichtliche schräg nach innen geneigte ebene Innenwandfläche E, F, F˝,E˝ (Bezugsziffer 19). Diese schräg nach innen geneigte Innenwandfläche 19 schneidet die vertikale Innenwandfläche 7 in einer zur Förderrichtung 8 im wesentlichen parallelen Schnittgeraden 20. Nun wird zwischen dem Punkt E‴, der auf der Höhe von D zwischen E und E˝ liegt und F ‴, der auf der Höhe von D zwischen F und F˝ liegt,ein Punkt G, beispielsweise in der Mitte zwischen E‴ und F‴ gewählt (Fig. 3). Nun wird dieser Punkt G mit E und F˝ verbunden und die Räume oberhalb der neuen Flächen DEG und DGF˝ in Gedanken entfernt, womit die in Fig. 4 gezeigten Innenwandflächen entstehen, nämlich die gegenüber der Förderrichtung 8 schräg nach oben ansteigende (und zugleich nach innen abfallende) "Hebefläche" DGF˝ (Bezugsziffer 18a) die daran anschließende, primär nach innen abfallende "Zulauffläche" DGE (Bezugsziffer 18b) und schließlich die im Punkt F˝ beginnende Ebene "Profilierfläche" F˝FEG (Bezugsziffer 19) . Die Profilierung gemäß der endgültigen Profileinschränkung 17 am Austragende beginnt also bereits beim Punkt F˝. Darüberliegendes Material wird zunächst durch die Hebefläche 18a im wesentlichen angehoben und kann anschließend über die schräg nach innen abfallende Zulauffläche 18b von oben auf das im mittleren Bereich geführte Material ohne Zwang gelangen.The position of the inner wall surfaces according to the invention will now be explained in more detail with reference to FIGS. 2 to 4, wherein FIGS. 2 and 3 only serve for better illustration and do not yet show the design of the inner wall surfaces according to the invention. 3 and 4, only the left inner wall is shown in perspective. The right inner wall is symmetrical with respect to the longitudinal center plane of the storage container. In order to obtain the inner wall surfaces according to the invention, the profile restriction E, F (reference number 17) necessary at the discharge end because of the prescribed clearance profile is parallel to itself against the conveying direction 8 up to the points E˝, F˝, further as the actual external profile restriction (starting at point D) pulled forward. This results in the flat inner wall surface E, F, F˝, E˝ visible in FIG. 3 (reference number 19). This inclined inwardly inclined inner wall surface 19 intersects the vertical inner wall surface 7 in a section line 20 which is essentially parallel to the conveying direction 8. Now between point E ‴, which is at the height of D between E and E˝, and F ‴, which is on the Height of D between F and F˝, a point G, for example in the middle between E ‴ and F ‴ selected (Fig. 3). Now this point G is connected to E and F˝ and the spaces above the new surfaces DEG and DGF˝ are removed in thought, which creates the inner wall surfaces shown in FIG "Lifting surface" DGF˝ (reference number 18a), the adjacent "inlet surface" DGE (reference number 18b) and finally the "profiling surface" F˝FEG level (reference number 19) beginning at point F˝. The profiling according to the final profile restriction 17 at the discharge end therefore already begins at point F˝. Overlying material is initially essentially lifted by the lifting surface 18a and can then easily reach the material guided in the central area from above via the inlet surface 18b, which slopes away inwardly.

Die in Fig. 4 gezeigten Innenwandflächen entsprechen einer Variante des erfindungsgemäßen Speicherbehälters, bei der die in einer Normalebene auf die Längsrichtung 8 des Speicherbehälters gemessene Breite der schrägen Innenwandfläche 19 ausgehend vom Austragende entgegen der Förderrichtung 8 abnimmt, bis die obere Begrenzungslinie 19a der schrägen Innenwandfläche 19 in einem Schnittpunktsbereich F˝ im wesentlichen auf die Schnittgerade 20 trifft. Zumindest vor diesem Schnittpunktsbereich F˝ erstrecken sich die vertikalen Innenwandflächen 7 im wesentlichen über die gesamte Seitenwandhöhe. Oberhalb der oberen Begrenzungslinie 19a der schrägen Innenwandfläche 19 schließt eine weitere Innenwandfläche stetig an, die beim vorliegenden Ausführungsbeispiel durch die zwei Teilflächen 18a, 18b gebildet ist. Diese weitere Innenwandfläche 18a, 18b steigt von der oberen Begrenzungslinie 19a nach außen an (bzw. fällt umgekehrt quer zur Förderrichtung 8 nach innen ab) . In einem an den Schnittpunktsbereich F˝ anschließenden Bereich F˝D schließt die weitere Innenwandfläche 18a(,18b) stetig an die vertikale Innenwandfläche 7 an, während sie gegen das Austragende hin (Bereich der Zulauffläche 18b) in ihrer Breite quer zur Förderrichtung abnimmt, vorzugsweise bis auf Null am Austragende. Unter einem "stetigen" Übergang von Flächen ist ein Übergang von Flächen ohne wesentliche Absätze oder dazwischenliegende Spalte gemeint. Ein "Knick" zwischen zwei stetig aneinander anschließenden Flächen ist selbstverständlich möglich.The inner wall surfaces shown in FIG. 4 correspond to a variant of the storage container according to the invention, in which the width of the inclined inner wall surface 19 measured in a normal plane in the longitudinal direction 8 of the storage container decreases from the discharge end against the conveying direction 8 until the upper boundary line 19a of the inclined inner wall surface 19 essentially meets intersection line 20 in an intersection area F˝. At least before this intersection area F˝, the vertical inner wall surfaces 7 extend essentially over the entire side wall height. Above the upper boundary line 19a of the inclined inner wall surface 19, a further inner wall surface adjoins, which in the present exemplary embodiment is formed by the two partial surfaces 18a, 18b. This further inner wall surface 18a, 18b rises outward from the upper boundary line 19a (or, conversely, falls inwards transversely to the conveying direction 8). In an area adjoining the intersection area F˝ F˝D the further inner wall surface 18a (12, 18b) continuously adjoins the vertical inner wall surface 7, while its width decreases transversely to the conveying direction towards the discharge end (area of the inlet surface 18b), preferably to zero at the discharge end. A "continuous" transition from surfaces means a transition from surfaces without significant paragraphs or gaps in between. A "kink" between two continuously adjoining surfaces is of course possible.

Bei dem hier beschriebenen Ausführungsbeispiel des erfindungsgemäßen Speicherbehälters geht (wie insbesondere auch aus Fig. 6 ersichtlich) die vertikale Innenwandfläche 7 oberhalb des Schnittpunktsbereiches F˝ ein Stück in Richtung Austragende weiter und die Schnittlinie F˝D zwischen dieser vertikalen Innenfläche und der weiteren Innenwandfläche 18a(,18b) steigt gegenüber der Förderrichtung 8 schräg nach oben an. Der Anstiegwinkel liegt günstigerweise zwischen 30 und 60 ° , womit dieser Bereich 18a der Innenwandfläche als Hebefläche für das Schüttgut in diesem Bereich wirkt. Die Ausbildung der oberhalb der oberen Begrenzungslinie 19a der schräg nach innen geneigten Innenwandfläche 19 liegenden weiteren Innenwandfläche in zwei Teilfächen 18a, 18b , die vorzugsweise eben sind, bietet vor allem herstellungstechnische Vorteile. Die gesamten Innenflächen können beispielsweise aus zusammengeschweißten, ebenen Flächen einfach hergestellt werden, ohne das Gewicht des Speicherbehälters wesentlich zu erhöhen.In the exemplary embodiment of the storage container according to the invention described here (as can also be seen in particular from FIG. 6), the vertical inner wall surface 7 extends a little further in the direction of the discharge end above the intersection area F˝ and the cutting line F˝D between this vertical inner surface and the further inner wall surface 18a (16b) rises obliquely upwards with respect to the conveying direction 8. The rise angle is advantageously between 30 and 60 °, so that this area 18a of the inner wall surface acts as a lifting surface for the bulk material in this area. The formation of the further inner wall surface lying above the upper boundary line 19a of the inner wall surface 19, which is inclined inwardly, in two partial surfaces 18a, 18b, which are preferably flat, offers above all manufacturing advantages. The entire inner surfaces can, for example, be easily produced from welded, flat surfaces without significantly increasing the weight of the storage container.

Eine sehr günstige Ausbildung der beiden Teilflächen 18a, 18b ist dann gegeben, wenn diese eben und dreieckig sind, wobei sie entlang einer Dreieckseite DG miteinander in Verbindung stehen, wobei die Spitze F˝ des einen Dreiecks 18a im wesentlichen entgegen die Förderrichtung 8 weist und die Spitze E des anderen Dreiecks 18b im obersten Bereichs des austragseitigen Endes der jeweiligen Seitenwand 6 liegt. Die erfindungsgemäßen Innenflächen bilden dann zusammen mit den Teilflächen der Seitenwand einen relativ einfachen geschlossenen gedachten Polyeder.A very favorable design of the two partial surfaces 18a, 18b is given if they are flat and triangular, they being along one side of the triangle DG are in communication with each other, the tip F˝ of one triangle 18a pointing essentially counter to the conveying direction 8 and the tip E of the other triangle 18b lying in the uppermost region of the discharge-side end of the respective side wall 6. The inner surfaces according to the invention then form a relatively simple closed imaginary polyhedron together with the partial surfaces of the side wall.

In den Fig. 7a - 7e ist eine Folge von Querschnitten durch die linke Hälfte des Speicherbehälters gezeigt, wobei die Lage der Schnitte aus Fig. 6 hervorgeht. In Fig. 7a befindet man sich noch vor der eigentlichen Profileinschränkung, man sieht die schräg nach oben ansteigende und nach innen abfallende Hebefläche sowie die entlang einer Knicklinie 21 (Linie DG) der vorhergehenden Figuren anschließende Zulauffläche 18b in einer Ansicht. Diese Ansicht der Flächen 18a und 18b täuscht ein wenig, da die Flächen 18a, 18b trotz gleicher Ansichtsfläche unterschiedlich ausgebildet sind. Die Hebefläche 18a steigt über eine raltiv kurze Länge steiler nach oben an, während die Zulauffläche ziemlich flach verläuft, sich aber dafür über einen größeren Bereich in Längsrichtung des Speicherbehälters erstreckt. Der Querschnitt gemäß Fig.7b ist im Bereich der Hebefläche 18 a gelegt und zeigt wie unterhalb der Fläche 18a bereits die ebene Profilierungsfläche beginnt. Der Rest der Fläche 18a und die Fläche 18b ist in einer Ansicht sichtbar. Der Schnitt gemäß Fig. 7c ist genau beim Übergang der Hebefläche 18a in die Zulauffläche 18b gelegt. Die unterhalb der Knicklinie 21 liegende Profilierungsfläche weist in diesem Bereich bereits die Hälfte der am Austragende vorhandene Breite quer zur Förderrichtung auf. Die Fläche 18b ist in Fig. 7c weiterhin nur in einer Ansicht ersichtlich. Fig. 7d zeigt einen Schnitt,der durch die Zulauffläche 18b verläuft. Aus Fig. 7d ist zunächst ersichtlich, daß an dieser Stelle bereits eine Profileinschränkung an der Außenwand (Bezugsziffer 6b) vorhanden ist, die nun gegen das Austragende hin laufend zunimmt. Weiters ist aus Fig. 7d ersichtlich, daß die Zulauffläche 18b unter einem Tiefenwinkel β in einer Horizontalen schräg nach unten abfällt, wobei der Tiefenwinkel mindestens 30 ° beträgt und vorzugsweise im Bereich von 45 ° liegt, wie dies beim gezeigten Ausführungsbeispiel der Fall ist. Diese Neigung nach unten ist nötig, damit das daraufliegende Material sicher zur Behältermitte hin nach unten fällt.A sequence of cross sections through the left half of the storage container is shown in FIGS. 7a-7e, the position of the cuts being shown in FIG. 6. In Fig. 7a one is still in front of the actual profile restriction, one can see the lifting surface that rises obliquely upwards and falls inwards as well as that along a kink line 21 (line DG ) of the preceding figures adjoining inlet surface 18b in a view. This view of the surfaces 18a and 18b is a little deceptive, since the surfaces 18a, 18b are designed differently despite the same view surface. The lifting surface 18a rises steeply upwards over a relatively short length, while the inlet surface runs fairly flat, but instead extends over a larger area in the longitudinal direction of the storage container. The cross section according to FIG. 7b is placed in the area of the lifting surface 18a and shows how the flat profiling surface already begins below the surface 18a. The rest of surface 18a and surface 18b are visible in one view. 7c is made exactly at the transition of the lifting surface 18a into the inlet surface 18b. The profiling surface below the kink line 21 already has half the width at the discharge end transverse to the conveying direction in this area. The surface 18b is furthermore only visible in one view in FIG. 7c. 7d shows a section which runs through the inlet surface 18b. From Fig. 7d it can first be seen that at this point there is already a profile restriction on the outer wall (reference number 6b), which now increases continuously towards the discharge end. 7d shows that the inlet surface 18b slopes obliquely downwards at a depth angle β in a horizontal direction, the depth angle being at least 30 ° and preferably in the range of 45 °, as is the case in the exemplary embodiment shown. This downward slope is necessary so that the material lying on it safely falls down towards the center of the container.

Die Fig. 7e zeigt einen Schnitt durch das Austragende. Dort weist die Profileinschränkung an der Außenseite des Speicherbehälters (6d) ihr größtes Ausmaß auf, die Breite der Profileinschränkung außen fällt in diesem Bereich mit der Breite der Profilierungsfläche 19 an der Innenwand zusammen.7e shows a section through the discharge end. There, the profile restriction on the outside of the storage container (6d) has its greatest extent, the width of the profile restriction on the outside coincides in this area with the width of the profiling surface 19 on the inner wall.

Die Erfindung ist selbstverständlich nicht auf die dargestellten Ausführungsbeispiele beschränkt. Beispielsweise kann die obere Begrenzungslinie der schräg nach innen eingeschrägten Innenwandfläche 19 auch in einer gekrümmten Linie verlaufen, wobei dann die darüberliegende, schräg nach außen ansteigende weitere Innenwandfläche eine gekrümmte Fläche ist. Solche gekrümmten Flächen sind im Hinblick auf eine gute Materialführung durchaus günstig, allerdings schwieriger herzustellen als die ebenen Innenwandflächen beim gezeigten Ausführungsbeispiel.The invention is of course not limited to the exemplary embodiments shown. For example, the upper boundary line of the inner wall surface 19, which is inclined inwards inwards, can also run in a curved line, in which case the further inner wall surface, which rises outwards and is inclined outwards, is a curved surface. Such curved surfaces are quite cheap in terms of good material management, but more difficult to manufacture than the flat inner wall surfaces in the embodiment shown.
