Abstract

For the purpose of refurbishment, a ballast bed (2) of a track (3) is taken up and cleaned in the form of an upper ballast layer (14) by a first clearing device (6). Bulk material (17) which is produced in the process is ejected laterally onto the ballast bed (2) in a bed zone (21) in front of the first clearing device (6) with respect to the working direction (5). Said bed zone (21) can only be picked up by the second clearing device (7), which is of wider design than the first clearing device (6) in the transverse direction of the track. This permits bulk material (17) which is produced in a front end region of a machine (1) to be intermediately stored for later use on the ballast bed (2).

Description

Die Erfindung betrifft ein Verfahren zur Sanierung einer Schotterbettung eines Gleises, wobei durch eine - bezüglich einer Arbeitsrichtung - erste Räumvorrichtung eine obere Bettungslage und durch eine nachfolgende zweite Räumvorrichtung eine an die obere Bettungslage angrenzende untere Bettungslage aufgenommen wird.The invention relates to a method for rehabilitating a ballast bed of a track, wherein an upper bedding layer is received by a first clearing device with respect to a working direction and a lower bedding layer adjacent to the upper bedding layer is taken up by a subsequent second clearing device.

Ein derartiges Verfahren ist durch EP 0 629 744 B1 bekannt. Dabei wird die obere, aus Schotter gebildete Bettungslage einem Steinbrecher zugeführt, um Kies zu erzeugen und diesen als Planumschutzschichte wieder zu verwenden. Die untere Bettungslage wird zur Gänze entsorgt und durch neuen Schotter ersetzt.Such a method is through EP 0 629 744 B1 known. In this case, the upper bedding layer formed from gravel is fed to a stone crusher to produce gravel and reuse it as a layer protective layer. The lower bedding layer is completely disposed of and replaced by new ballast.

Gemäß EP 0 408 837 B1 ist es auch bekannt, durch vordere Räumketten aufgenommenen Schotter zu reinigen und anschließend zur Zwischenlagerung auf das Gleis abzuwerfen. Der zwischengelagerte Schotter wird durch eine spezielle Einrichtung über die nachfolgende Räumkette transportiert und dann auf das freigelegte Erdplanum abgeworfen.According to EP 0 408 837 B1 It is also known to clean up ballast picked up by front clearing chains and then dump it onto the track for temporary storage. The interposed gravel is transported through a special facility on the subsequent clearing chain and then dropped onto the exposed Erdplanum.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Verfahrens der eingangs genannten Art, mit dem eine effizientere Zwischenlagerung von Schüttgut möglich ist.The object of the present invention is now to provide a method of the type mentioned, with a more efficient intermediate storage of bulk material is possible.

Diese Aufgabe wird erfindungsgemäß mit einem Verfahren der gattungsgemäßen Art dadurch gelöst, dass Schüttgut - bezüglich der Arbeitsrichtung - vor der ersten Räumvorrichtung seitlich auf die Schotterbettung in einer Bettungszone abgeworfen wird, die lediglich von der zweiten - bezüglich einer Gleisquerrichtung breiter als die erste Räumvorrichtung ausgebildeten - Räumvorrichtung erfasst wird, so dass das abgeworfene Schüttgut gemeinsam mit der unteren Bettungslage durch die zweite Räumvorrichtung aufgenommen wird.This object is achieved with a method of the generic type in that bulk material - with respect to the working direction - is thrown laterally before the first clearing device on the ballast bed in a ballast zone, the only of the second - formed with respect to a track transverse direction wider than the first clearing device - Clearing device is detected, so that the dropped bulk material is taken together with the lower bedding layer by the second clearing device.

Der aus diesem Verfahren resultierende besondere Vorteil liegt darin, dass sich eine eigene Förderbandstrasse zum Rücktransport von Schüttgut erübrigt. Es ist nunmehr in vorteilhafter Weise möglich, Schüttgut nach kurzzeitiger Zwischenlagerung ohne spezielle Hilfsmaßnahmen zur Gänze durch die zweite Räumkette aufzunehmen. Mit der speziellen seitlichen Lagerung ist es außerdem ohne Hilfseinrichtungen möglich, das Schüttgut störungsfrei an der ersten Räumkette vorbei zu schleusen, wobei deren Leistung in keiner Weise beeinträchtigt wird.The special advantage resulting from this method is that a separate conveyor belt road for the return transport of bulk material is unnecessary. It is now possible in an advantageous manner to receive bulk material after temporary storage without special aid measures wholly by the second clearing chain. With the special lateral storage, it is also possible without auxiliary equipment, the bulk material to pass smoothly past the first clearing chain, the performance of which is in no way impaired.

Weitere Vorteile der Erfindung ergeben sich aus dem Unteranspruch und der Zeichnungsbeschreibung.Further advantages of the invention will become apparent from the dependent claim and the drawing description.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigen:In the following the invention will be described with reference to an embodiment shown in the drawing. Show it:

Fig. 1 eine vereinfachte Seitenansicht einer Maschine zur Sanierung einer Schotterbettung, Fig. 2 eine Draufsicht auf die Maschine, und Fig. 3 einen vereinfachten Querschnitt durch ein vorderes Ende der Maschine. Fig. 1 a simplified side view of a machine for rehabilitation of a ballast bed, Fig. 2 a plan view of the machine, and Fig. 3 a simplified cross section through a front end of the machine.

Eine in Fig. 1 ersichtliche Maschine 1 ist ein Teil eines nicht näher dargestellten und aus mehreren Fahrzeugen gebildeten Umbauzuges zur Sanierung einer Schotterbettung 2 eines Gleises 3. Zwischen zwei Schienenfahrwerken 4 sind - bezüglich einer Arbeitsrichtung 5 - eine vordere bzw. erste Räumvorrichtung 6 und eine nachfolgende zweite Räumvorrichtung 7 mit einem Maschinenrahmen 8 verbunden. Jede höhen- und seitenverstellbare Räumvorrichtung 6, 7 ist mit einem Antrieb 9 für eine Rotation einer endlosen, um das Gleis 3 herumgeführten Räumkette 10 (s. Fig. 3) ausgestattet. Das Gleis 3 wird durch eine Hebeeinrichtung 11 zwischen den beiden Schienenfahrwerken 4 geringfügig angehoben.An in Fig. 1 apparent machine 1 is a part of a Umbauzuges not shown in detail and formed from several vehicles for rehabilitation of a ballast bed 2 of a track 3. Between two rail bogies 4 - with respect to a working direction 5 - a front or first clearing device 6 and a subsequent second clearing device 7 with a machine frame 8 connected. Each height and side adjustable broaching device 6, 7 is provided with a drive 9 for rotation of an endless, around the track 3 guided around Räumkette 10 (s. Fig. 3 ) fitted. The track 3 is slightly raised by a lifting device 11 between the two rail bogies 4.

Wie in Fig. 2 und 3 ersichtlich, ist ein normal zur Gleislängsrichtung sowie unterhalb des Gleises 3 verlaufender Kettenabschnitt 12 der zweiten Räumvorrichtung 7 breiter ausgebildet als ein entsprechender Kettenabschnitt 13 der ersten Räumvorrichtung 6.As in Fig. 2 and 3 can be seen, a normal to the track longitudinal direction and below the track 3 extending chain section 12 of the second clearing device 7 is formed wider than a corresponding chain section 13 of the first clearing device. 6

Im folgenden wird an Hand der Fig. 1 bis 3 ein Verfahren zur Sanierung der Schotterbettung 2 näher beschrieben.The following will be on hand Fig. 1 to 3 a method for rehabilitation of the ballast bed 2 described in more detail.

Die Maschine 1 wird zur Sanierung der Schotterbettung 2 kontinuierlich in der Arbeitsrichtung 5 verfahren. Dabei erfolgt eine permanente Aufnahme einer oberen, aus Schotter 15 gebildeten Bettungslage 14 durch die erste Räumvorrichtung 6. Der aufgenommene Schotter 15 wird über eine Förderbandstraße 16 einer nicht näher dargestellten, an einem vorderen Maschinenende positionierten Siebanlage zugeführt und gereinigt. Dabei erfolgt ein Ausscheiden eines aus Kleinschotter und Abraum gebildeten Schüttgutes 17, das im Bereich der Siebanlage über ein Querförderband 18 seitlich auf die Schotterbettung 2 abgeworfen wird. Der Abwurf erfolgt in einem seitlichen Abschnitt der Schotterbettung 2, der von der ersten, eine Breite b1 aufweisenden Räumvorrichtung 6 nicht erfasst wird.The machine 1 is moved to refurbish the ballast bed 2 continuously in the working direction 5. In this case, a permanent inclusion of an upper bedding layer 14 formed by ballast 15 takes place through the first Reaming device 6. The recorded ballast 15 is fed and cleaned via a conveyor belt 16 a not shown, positioned at a front end of the machine screen. In this case, there is a separation of a bulk material 17 formed from small gravel and overburden, which is thrown laterally on the ballast bed 2 in the area of the screening plant via a transverse conveyor belt 18. The discharge takes place in a lateral portion of the ballast bed 2, which is not detected by the first, a width b1 having clearing device 6.

Das lediglich in einer seitlichen Bettungszone 21 zur Zwischenlagerung abgeworfene Schüttgut 17 wird schließlich durch die nachfolgende, eine Breite b2 aufweisende zweite Räumvorrichtung 7 gemeinsam mit einer unteren Bettungslage 19 erfasst und auf ein Förderband 20 für einen Weitertransport abgeworfen. Das aus Kleinkorn, Schotterabrieb und Erde zusammengesetzte Gemisch der unteren Bettungslage 19 sowie des zwischengelagerten Schüttgutes 17 wird mit Zuschlagstoffen vermischt und anschließend zur Bildung einer Planumschutzschichte auf ein planiertes Erdplanum abgeworfen.The bulk material 17 dropped for intermediate storage only in a lateral bedding zone 21 is finally grasped by the following second clearing device 7, having a width b2, together with a lower bedding layer 19 and dropped onto a conveyor belt 20 for onward transport. The composite of small grain, gravel and soil mixture of the lower bedding layer 19 and the intermediate stored bulk material 17 is mixed with aggregates and then dropped to form a Planumschutzschichte on a planed Erdplanum.
