Description

Die Erfindung betrifft eine Maschine nach den im Oberbegriff von Anspruch 1 angeführten Merkmalen.The invention relates to a machine according to the features cited in the preamble of claim 1.

Gemäß EP 0 512 075 ist eine Maschine bekannt, bei der mit Hilfe von Schaufelrädern im Flankenbereich einer Schotterbettung gelegener Schotter aufgenommen und gereinigt wird. Der unterhalb des Gleises vorhandene Schotter wird durch einen Undercutter erfasst, einer Siebanlage zur Reinigung zugeführt und schließlich über dem Gleis abgeworfen.According to EP 0 512 075 a machine is known in which with the help of paddles located in the flank area of a ballast gravel and is cleaned. The gravel below the track is detected by an undercutter, fed to a screening plant for cleaning and finally dropped over the track.

Durch DE 2 226 612 ist eine weitere Maschine bekannt, bei der unterhalb des Gleises gelegener Schotter durch einen Undercutter in den Flankenbereich verlagert wird. In diesem Bereich der Schotterbettung kommt eine endlose Räumkette zum Einsatz, um den durch den Undercutter seitlich verlagerten Schotter aufzunehmen und einer Siebanlage zuzuführen.By DE 2 226 612 Another machine is known in which located below the track gravel is displaced by an undercutter in the flank area. In this area of the ballast bedding, an endless clearing chain is used to pick up the ballast that has been laterally displaced by the undercutter and to feed it to a screening plant.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Maschine der eingangs genannten Art, mit der eine vereinfachte Reinigung insbesondere von Weichenabschnitten durchführbar ist.The object of the present invention is now to provide a machine of the type mentioned, with a simplified cleaning in particular of points sections is feasible.

Diese Aufgabe wird erfindungsgemäß mit einer Maschine der gattungsgemäßen Art durch die im Kennzeichen von Anspruch 1 angeführten Merkmale gelöst.This object is achieved with a machine of the generic type by the features cited in the characterizing part of claim 1.

Die Reinigung insbesondere von Weichenabschnitten wird mit Hilfe der Erfindung insofern vereinfacht, als durch die zweistufige Schotteraufnahme auch die in Weichenabschnitten anfallenden größeren Schottermengen in zwei getrennten Durchgängen gereinigt werden können. Somit kann auch eine weniger leistungsfähige Siebanlage eingesetzt werden. Es erübrigt sich auch eine technisch schwierige Übergabe des Schotters vom Undercutter direkt auf eine Vorrichtung zum Hochfördern.The cleaning in particular of switch sections is simplified with the aid of the invention insofar as by the two-stage ballast receptacle It is also possible to clean the larger quantities of ballast produced in switch sections in two separate passages. Thus, a less powerful screen can be used. It is also unnecessary for a technically difficult transfer of the ballast from the undercutter directly to a device for upfeed.

Weitere Vorteile der Erfindung ergeben sich aus den weiteren Ansprüchen und der Zeichnungsbeschreibung.Further advantages of the invention will become apparent from the other claims and the description of the drawings.

Im Folgenden wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben. Es zeigen: Fig. 1 und 2 je einen vorderen bzw. hinteren Teil einer Maschine zum Reinigen von Schotter in Seitenansicht, Fig. 3 eine schematische Draufsicht auf die genannte Maschine, und Fig. 4 eine nicht erfindungsgemäße Maschine.In the following the invention will be described in more detail with reference to embodiments shown in the drawing. Show it: Fig. 1 and 2 each a front or rear part of a machine for cleaning ballast in side view, Fig. 3 a schematic plan view of said machine, and Fig. 4 a machine not according to the invention.

Eine in Fig. 1 und 2 dargestellte Maschine 1 setzt sich aus mehreren in einer Arbeitsrichtung 2 hintereinander angeordneten und zu einem Zugverband gekuppelten Maschinenrahmen 3 und Schienenfahrwerken 4 zusammen. Auf einem vorderen Maschinenrahmen 3 ist eine Flankenaufnahmeeinrichtung 5 zur Aufnahme von Schotter 6 aus einem an Schwellenenden 30 angrenzenden Bettungsabschnitt 7 (s. Fig. 3) einer Schotterbettung 8 eines Gleises 9 angeordnet. Die Flankenaufnahmeeinrichtung 5 besteht aus einer durch einen Antrieb 10 höhenverstellbaren Förderkette 11, die in einer parallel zum Gleis 9 verlaufenden vertikalen Ebene rotierbar ist und zur Übergabe des aufgenommenen Schotters 6 auf eine Fördereinheit 12 vorgesehen ist.An in Fig. 1 and 2 illustrated machine 1 is composed of several in a direction of work 2 arranged one behind the other and coupled to a train machine frame 3 and rail bogies 4 together. On a front machine frame 3, a flank receiving device 5 for receiving ballast 6 from a bedding section 7 adjacent to sleeper ends 30 (see FIG. Fig. 3 ) arranged a ballast 8 8 a track 9. The flank receiving device 5 consists of a height adjustable by a drive 10 conveyor chain 11 which is rotatable in a plane parallel to the track 9 vertical plane and the Transfer of the recorded ballast 6 is provided on a conveyor unit 12.

Diese endet oberhalb einer Siebanlage 13. Unterhalb dieser ist eine weitere Fördereinheit 14 zum Abtransport von Abraum sowie eine Fördereinheit 15 zum Weitertransport des gereinigten Schotters in einen Speicher 16 zur Zwischenspeicherung vorgesehen. Dieser weist ein großes Speichervermögen sowie eine Fördereinheit 17 zu Selbstentladung auf.This ends above a sieve 13. Below this, a further conveyor unit 14 for the removal of overburden and a conveyor unit 15 is provided for further transport of the cleaned ballast in a memory 16 for temporary storage. This has a large storage capacity and a conveyor unit 17 for self-discharge.

Der an den Speicher 16 anschließende Maschinenrahmen 3 ist mit einem sogenannten Undercutter 18 ausgestattet, der aus einer durch einen Antrieb 19 in einer parallel zu einer Gleisebene rotierbaren Förderkette 20 gebildet ist. Diese ist von einer in Fig. 2 ersichtlichen Außerbetriebstellung in eine in Fig. 3 angedeutete Arbeitsposition unter das Gleis 9 verschwenkbar. Bezüglich der Arbeitsrichtung 2 der Maschine 1 unmittelbar hinter dem Undercutter 18 ist eine als Schurre ausgebildete Vorrichtung 21 zum Abwurf des gereinigten Schotter 6 auf das Gleis 9 sowie eine Gleishebevorrichtung 22 vorgesehen.The adjoining the memory 16 machine frame 3 is equipped with a so-called undercutter 18, which is formed from a rotatable by a drive 19 in a parallel to a track plane conveyor chain 20. This is from an in Fig. 2 apparent decommissioning in an in Fig. 3 indicated working position under the track 9 pivoted. With regard to the working direction 2 of the machine 1 directly behind the undercutter 18, a device 21 designed as a chute for discharging the cleaned ballast 6 onto the track 9 and a track lifting device 22 are provided.

Zusätzlich zur Gleishebevorrichtung 22 ist eine unmittelbar hinter dem Undercutter 18 angeordnete Zusatzhebevorrichtung 23 zum Anheben einer in einem Weichenabschnitt 24 (s. Fig. 3) vorgesehenen Schiene 25 eines Abzweiggleises 26 vorgesehen. Die Vorrichtung 21 zum Abwurf des gereinigten Schotters 6 ist durch eine weitere Fördereinheit 27 mit dem Speicher 16 verbunden.In addition to the track lifting device 22, an additional lifting device 23 arranged directly behind the undercutter 18 for lifting one in a switch section 24 (see FIG. Fig. 3 ) provided rail 25 of a branch track 26. The device 21 for discharging the cleaned ballast 6 is connected to the reservoir 16 by a further conveying unit 27.

Im folgenden wird das Verfahren zur Reinigung der Schotterbettung 8 in einem Weichenabschnitt 24 anhand der Fig. 1 bis 3 näher beschrieben. Im Rahmen einer ersten Maschinenvorfahrt sowie eines ersten Verfahrensschrittes wird der im genannten und nunmehr vertieften Bettungsabschnitt 7 vorhandene Schotter 6 mit Hilfe der Flankenaufnahmeeinrichtung 5 aufgenommen und gereinigt. Parallel dazu - bezüglich der Arbeitsrichtung 2 dahinter - erfolgt in einem zweiten Verfahrensschritt eine Verlagerung des unterhalb des Gleises 9 gelegenen Schotters 6 in den genannten Bettungsabschnitt 7. Dies wird durch den Einsatz des unter das Gleis eingeschwenkten Undercutters 18 erreicht. Dabei ist von Vorteil, dass durch den vorausgegangenen Schotteraushub die Verlagerung des unterhalb des Gleises 9 vorhandenen Schotters in den an die Schwellenenden 30 anschließenden Bettungsabschnitt 7 erleichtert wird.In the following, the method for cleaning the ballast bed 8 in a switch section 24 on the basis of Fig. 1 to 3 described in more detail. As part of a first machine approach and a first method step, the existing in said and now recessed ballast section 7 gravel 6 is received and cleaned by means of the flank receiving device 5. Parallel thereto - with respect to the working direction 2 behind it - in a second process step, a displacement of the located below the track 9 ballast 6 in said bedding section 7. This is achieved by the use of the swung under the track Undercutters 18. It is advantageous that the displacement of the existing below the track 9 ballast is facilitated in the adjoining the threshold ends 30 Bettungsabschnitt 7 by the previous gravel excavation.

Während der Arbeit im Weichenabschnitt 24 werden sowohl die beiden Schienen eines Hauptgleises 28 als auch eine Schiene 25 des Abzweiggleises 26 erfasst, um eine ausreichende Fixierung der Weiche zu erreichen.During work in the switch section 24, both the rails of a main track 28 and a rail 25 of the branch track 26 are detected in order to achieve a sufficient fixation of the switch.

Der durch die Flankenaufnahmeeinrichtung 5 aufgenommene Schotter 6 wird nach der Reinigung in einem jeweils erforderlichen Ausmaß im Speicher 16 zwischengelagert und unmittelbar nach dem Einsatz des Undercutters 18 über die Vorrichtung 21 auf das Gleis 9 abgeworfen. Damit erfolgt eine rasche Wiederherstellung der unter dem Gleis 9 befindlichen Schotterbettung.The ballast 6 accommodated by the flank receiving device 5 is temporarily stored in the storage 16 after cleaning to the extent required in each case and dropped onto the track 9 immediately after the use of the undercut 18 via the device 21. This is a rapid restoration of the ballast bed located under the track 9.

Nachdem das Ende des Weichenabschnittes 24 (bis zu dem die Länge des Undercutters 18 noch ausreichend ist) erreicht wurde, erfolgt eine Überstellung der Flankenaufnahmeeinrichtung 5 und des Undercutters 18 in eine Außerbetriebstellung. Anschließend wird die Maschine 1 bis zum Anfang des Weichenabschnittes 24 zurückgefahren.After the end of the points section 24 (up to which the length of the undercut 18 is still sufficient) has been reached, a transfer of the flank receiving device 5 and the undercut 18 takes place into an inoperative position. Subsequently, the machine 1 is moved back to the beginning of the switch section 24.

Während der nachfolgenden zweiten Maschinenvorfahrt bleibt der Undercutter 18 in der Außerbetriebstellung. Der zuvor im zweiten Verfahrensschritt durch den Undercutter 18 in den Bettungsabschnitt 7 verlagerte Schotter 6 wird nun in einem dritten Verfahrensschritt mit Hilfe der Flankenaufnahmeeinrichtung 5 aufgenommen, gereinigt und über eine Schurre 29 wiederum in den Bettungsabschnitt 7 abgeworfen.During the subsequent second machine advance the undercutter 18 remains in the inoperative position. The previously moved in the second step by the undercutter 18 in the bedding section 7 gravel 6 is now received in a third process step using the flank receiving device 5, cleaned and dropped over a chute 29 turn into the bedding section 7.

Die Reinigung eines Weichenabschnittes 24 ist mit diesem Verfahren insofern sehr vorteilhaft, als jeweils durch eine geringfügige Verschwenkung des Undercutters 18 um eine vertikale Schwenkachse eine rasche und einfache Anpassung an die sich permanent ändernde Breite der Weiche möglich ist. Ebenso kann die Flankenaufnahmeeinrichtung 5 problemlos an den Weichenverlauf angepasst werden. Dies kann ohne Unterbrechung der Maschinenvorfahrt durchgeführt werden. Mit dem erfindungsgemäßen Verfahren ist es selbstverständlich auch möglich, einen weichenfreien Gleisabschnitt im Rahmen der beschriebenen Verfahrensschritte zu reinigen.The cleaning of a switch section 24 is so far very advantageous with this method, as in each case by a slight pivoting of the Undercutters 18 about a vertical pivot axis a quick and easy adaptation to the permanently changing width of the switch is possible. Likewise, the flank receiving device 5 can be easily adapted to the turnout course. This can be done without interrupting the machine approach. Of course, it is also possible with the method according to the invention to clean a soft-free track section within the scope of the described method steps.

Wie in Fig. 3 ersichtlich, ist es zweckmäßig, zwei
Flankenaufnahmeeinrichtungen 5 parallel einzusetzen. Es ist im Rahmen der Erfindung natürlich auch möglich, zwei Undercutter 18 einzusetzen, die jeweils von einer Gleislängsseite in Richtung zur Gleismitte eingeschwenkt werden. Dabei wird der unter dem Gleis befindliche Schotter etwa jeweils zur Hälfte in den angrenzenden Bettungsabschnitt 7 verlagert.As in Fig. 3 it is expedient, two
Insert flank receiving devices 5 in parallel. It is of course also possible in the context of the invention to use two undercutter 18, which are each pivoted in from one side of the track in the direction of the track center. In this case, the ballast located under the track is about half each shifted to the adjacent bedding section 7.

Bei einer in Fig. 4 ersichtlichen nicht erfindungsgemäßen Variante einer Maschine 1 ist im wesentlichen lediglich insofern eine konstruktive Änderung vorgesehen, als der Undercutter 18, die Gleishebeeinrichtung 22 und die Vorrichtung 21 zur Schottereinbringung in Arbeitsrichtung 2 vor der Flankenaufnahmeeinheit 5 angeordnet sind. Bedarfsweise kann auch ein mit neuem Schotter gefüllter Speicherwagen in der Maschine 1 enthalten sein, um bedarfsweise neuen Schotter zuführen zu können.At an in Fig. 4 The variant of a machine 1 which is not according to the invention is substantially modified insofar as the undercutter 18, the track lifting device 22 and the device 21 for bulkhead loading in the working direction 2 are arranged in front of the flange receiving unit 5. If necessary, a filled with new gravel storage trolley may be included in the machine 1, if necessary, to be able to supply new gravel.

Im Rahmen einer Verfahrensvariante ist es auch möglich, den mit Hilfe des Undercutters 18 unterhalb der Weiche entfernten Schotter nicht zu reinigen, sondern im genannten Bettungsabschnitt 7 lediglich zu planieren. Anschließend wird neuer Schotter zur vollständigen Wiederherstellung des Bettungsabschnittes 7 auf den planierten alten Schotter abgeworfen..In the context of a variant of the method, it is also possible not to clean the gravel removed with the aid of the undercutter 18 below the switch, but merely to level it in said bedding section 7. Subsequently, new gravel is thrown to the complete restoration of the bedding section 7 on the leveled old gravel.
