Abstract

A ballast-sweeping system (1) provided for receiving and distributing ballast situated on a track comprises a sweeping brush (3) which can be rotated about an axis of rotation (2), a ballast conveyor belt (5) arranged upstream with respect to a brush direction of rotation (4), and a ballast guide plate (7) which is positioned between the sweeping brush (3) and ballast conveyor belt (5) and intended for transferring the ballast onto the ballast conveyor belt (5). A length of the ballast conveyor belt (5) that is delimited by two deflection ends (8) is designed to be shorter than a length of the sweeping brush (3) that extends in the axis of rotation (2). In addition, the ballast conveyor belt (5) is designed so as to be displaceable in the transporting direction (6) relative to the sweeping brush (3) by means of a drive (10). Therefore, optimized ballast distribution in tamping zones (15) of the track (9) is possible.

Description

Schotterkehranlage zur Aufnahme und Verteilung von auf einem Gleis befindlichem Schotter  Gravel sweeper for receiving and distributing ballast on a track
[01] Die Erfindung betrifft eine Schotterkehranlage zur Aufnahme und Verteilung von auf einem Gleis befindlichem Schotter, bestehend aus einer um eine Drehachse rotierbaren Kehrbürste, einem bezüglich einer Bürsten- drehrichtung vorgeordnetem Schotterförderband mit einer parallel zur Drehachse verlaufenden Transportrichtung, und mit einem zwischen Kehrbürste und Schotterförderband positionierten Schotterleitblech zur Weiterleitung des Schotters auf das Schotterförderband. [0001] The invention relates to a ballast sweeper for picking up and distributing ballast on a track, comprising a sweeping brush rotatable about a rotation axis, a ballast conveyor upstream of a brush rotation direction with a transport direction parallel to the rotation axis, and a sweeper between Ballast conveyor belt positioned gravel baffle for forwarding the ballast on the ballast conveyor belt.
[02] Derartige Schotterkehranlagen werden häufig in Verbindung mit einem  [02] Such gravel sweepers are often associated with a
Schotterpflug verwendet und sind beispielsweise durch DE 911 02 31 111 oder EP 2 250 318 bekannt. Dabei wird überschüssiger Schotter vom Gleis abgekehrt und einem Förderband für einen Abwurf im Flankenbereich des Gleises zugeführt.  Ballast plow used and are known for example from DE 911 02 31 111 or EP 2 250 318. This excess gravel is turned away from the track and fed to a conveyor belt for a discharge in the flank area of the track.
[03] Durch WO 2013/189564 ist auch ein Schotterpflug mit einem Schottersilo zum Zwischenspeichern großer Schottermengen bekannt. Falls der Schottersilo voll ist, kann dieser mithilfe eines querverschiebbaren Förderbandes in den Flankenbereich des Gleises abgeworfen werden.  [03] WO 2013/189564 also discloses a ballast plow with a ballast silo for temporarily storing large amounts of ballast. If the ballast silo is full, it can be thrown into the flank area of the track by means of a transversely displaceable conveyor belt.
[04] Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer  [04] The object of the present invention is now to provide a
Schotterkehranlage der eingangs genannten Art, mit der eine verbesserte Schotterverteilung möglich ist. [05] Diese Aufgabe wird erfindungsgemäß mit einer Schotterkehranlage der gattungsgemäßen Art dadurch gelöst, dass eine durch zwei Umlenkenden begrenzte Länge des Schotterförderbandes kürzer ausgebildet ist als eine in Drehachse verlaufende Länge der Kehrbürste, und dass das Schotterförderband durch einen Antrieb in der Transportrichtung verschiebbar ausgebildet ist. Gravel plant of the type mentioned, with the improved ballast distribution is possible. [05] This object is achieved with a ballast sweeper of the generic type in that a limited by two deflecting length of the ballast conveyor belt is shorter than a running axis of rotation in the sweeping brush, and that the ballast conveyor belt is slidably formed by a drive in the transport direction ,
[06] Mit dieser speziellen Ausbildung des Schotterförderbandes ist es nunmehr in vorteilhafter Weise möglich, durch die Kehrbürste aufgenommenen überschüssigen Schotter bedarfsweise und gezielt in die Stopfzonen des Gleises abzuwerfen, um schließlich eine qualitativ gleichmäßige Unter- stopfung zu ermöglichen. Folglich erübrigt sich eine bisher übliche Entsorgung des überschüssigen Schotters in den Flankenbereich und eine daraus folgende unwirtschaftliche Schotteranhäufung.  [06] With this special design of the ballast conveyor belt, it is now possible in an advantageous manner to throw off excess ballast picked up by the sweeping brush as needed and purposefully into the stuffing zones of the track, in order to finally enable qualitatively uniform undercutting. Consequently, a hitherto customary disposal of the excess gravel in the flank area and a consequent uneconomical gravel accumulation is unnecessary.
[07] Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen und der Zeichnungsbeschreibung.  [07] Further advantages of the invention will become apparent from the dependent claims and the drawing description.
[08] Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigen: Fig. 1 eine Ansicht einer Schotterkehranlage in einer Gleislängsrichtung, Fig. 2 und 3 je einen Querschnitt durch die Schotterkehranlage, Fig. 4 eine maximale Verschiebung eines Schotterförderbandes, und Fig. 5 eine vereinfachte Draufsicht auf eine alternative Ausführung der Schotterkehranlage. [09] Eine in den Fig. 1 bis 5 dargestellte Schotterkehranlage 1 zur Aufnahme und Verteilung von auf einem Gleis befindlichem Schotter besteht aus einer um eine Drehachse 2 rotierbaren Kehrbürste 3, einem bezüglich einer Bürstendrehrichtung 4 vorgeordnetem Schotterförderband 5 mit einer parallel zur Drehachse 2 verlaufenden Transportrichtung 6. Zwischen der Kehrbürste 3 und dem Schotterförderband 5 befindet sich ein geneigt angeordnetes Schotterleitblech 7 zur Weiterleitung des durch die Kehrbürste 3 erfassten Schotters auf das Schotterförderband 5. [08] In the following the invention will be described in more detail with reference to an embodiment shown in the drawing. 2 shows a cross section through the ballast sweeper, FIG. 4 shows a maximum displacement of a ballast conveyor belt, and FIG. 5 shows a simplified plan view of an alternative embodiment of the ballast sweeper. [01] A ballast sweeper 1 shown in FIGS. 1 to 5 for receiving and distributing ballast located on a track consists of a sweeping brush 3 rotatable about a rotation axis 2, a ballast conveyor belt 5 arranged parallel to the rotation axis 2 and arranged upstream of a brush rotation direction 4 Transport direction 6. Between the sweeping brush 3 and the ballast conveyor belt 5 there is an inclined gravel guide plate 7 for conveying the grit detected by the sweeping brush 3 onto the ballast conveyor belt 5.
[10] Eine durch zwei Umlenkenden 8 begrenzte Länge ls des Schotterförderbandes 5 ist kürzer ausgebildet ist als eine in der Drehachse 2 verlaufende Länge Ikder Kehrbürste 3. Vorzugsweise ist die Länge ls des Schotterförderbandes 5 etwa einer Spurweite eines abzukehrenden Gleises 9 entsprechend ausgebildet. A limited by two deflecting 8 length l s of the ballast conveyor belt 5 is formed shorter than a running in the axis of rotation 2 length Ikder sweeping brush 3. Preferably, the length l s of the ballast conveyor belt 5 about a track of a track to be turned away 9 is designed accordingly.
1] Das Schotterförderband 5 ist durch einen Antrieb 10 in der Transportrichtung 6 relativ zur Kehrbürste 3 sowie parallel zur Drehachse 2 in beiden Richtungen verschiebbar ausgebildet. Der Verschiebeweg ist vorzugsweise derart bemessen, dass jedes Umlenkende 8 von der in Fig. 1 ersichtlichen Position jeweils bis zu einem angrenzenden, näher gelegenen Ende der Kehrbürste 3 bewegbar ist. Mithilfe eines reversiblen Drehantriebes 12 kann der Schotter durch Umkehr der Transportrichtung 6 wahlweise zum einen oder anderen Umlenkende 8 verlagert werden. ] Unterhalb des Schotterförderbandes 5 sind zwei - in der Transportrichtung 6 in einem der Spurweite des Gleises 9 entsprechenden Abstand voneinander distanzierte - Abdeckbleche 13 zur Vermeidung eines Schotterabwurfes auf schienen 14 des Gleises 9 angeordnet. An beide Längsseiten der Schiene 14 angrenzend befinden sich die für eine Unterstopfung des Gleises 9 wesentlichen Stopfzonen 15.1] The ballast conveyor belt 5 is formed by a drive 10 in the transport direction 6 relative to the sweeping brush 3 and parallel to the axis of rotation 2 in both directions displaced. The displacement path is preferably dimensioned such that each deflection end 8 is movable from the position shown in FIG. 1 in each case to an adjacent, closer end of the sweeping brush 3. By means of a reversible rotary drive 12, the ballast can be displaced by reversing the transport direction 6 either to one or the other deflection end 8. ] Below the ballast conveyor belt 5 are two - spaced in the transport direction 6 in a track width of the track 9 distance distanced - cover plates 13 to avoid a ballast on rails 14 of the track 9. Adjacent to both longitudinal sides of the rail 14 are the stuffing zones 15 which are essential for a clogging of the track 9.
] Durch die Verschiebbarkeit des Schotterförderbandes 5 besteht beispielsweise - im Falle eines in Fig. 4 in Gleisrichtung gesehen linken Nachbargleises - die Möglichkeit, durch maximale Verschiebung zum Nachbargleis von der Kehrbürste 3 erfassten Schotter in die Stopfzonen 15 der vom Nachbargleis weiter entfernten Schiene 14 abzuwerfen. Dies ist insbesondere dann von Vorteil, wenn in einer Gleisquerneigung (s. Fig. 4) diese Schiene 14 höher gelegen ist. In dieser Situation besteht häufig das Problem, dass im Bereich der höher gelegenen Schiene zu wenig Schotter für eine optimale Unterstopfung vorhanden ist.By the displaceability of the ballast conveyor belt 5, for example, in the case of a left-hand side track seen in the track direction in FIG. 4, it is possible to drop gravel captured by the sweeping brush 3 into the stuffing zones 15 of the track 14 farther from the neighboring track by maximum displacement to the neighboring track. This is particularly advantageous when in a track bank (see Fig. 4), this rail 14 is located higher. In this situation, there is often the problem that there is too little ballast in the area of the higher rail for optimum underfoaming.
] Es kann aber auch in der in Fig. 1 ersichtlichen mittigen Grundposition des Schotterförderbandes 5 in vorteilhafter Weise Schotter durch rasche Umkehr der Transportrichtung 6 bedarfsweise in die Stopfzone der linken oder der rechten Schiene 14 abgeworfen werden.] However, in the central basic position of the ballast conveyor belt 5 apparent in FIG. 1, ballast can advantageously be thrown off into the stuffing zone of the left or right-hand rail 14 by rapid reversal of the transport direction 6 as required.
] Wie in Fig. 5 ersichtlich, ist in einer alternativen Zusatzausstattung jeweils an einem Endbereich des Schotterleitbleches 7 eine Umlenkplatte 16 vorgesehen. Diese ist mit dem Schotterleitblech 7 verbunden und um eine normal zu einer Ebene des Schotterleitbleches 7 verlaufende Schwenkachse von einer in strichlierter Linie dargestellten Position in eine in voller Linie dargestellte Umlenkposition verschwenkbar. In dieser Lage wird der Schotter zur Ablage auf das Schotterförderband 5 umgelenkt, wenn sich dieses in der in Fig. 4 dargestellten maximalen linken Position befindet. As can be seen in FIG. 5, in an alternative additional equipment, a deflecting plate 16 is provided in each case at an end region of the ballast guide plate 7. This is connected to the ballast guide plate 7 and a normal to a plane of the ballast guide plate 7 extending pivot axis of a position shown in dashed line position in a deflection position shown in full line. In this position, the ballast is deflected for storage on the ballast conveyor belt 5, when this is in the maximum left position shown in Fig. 4.
