Description

Die Erfindung betrifft ein Verfahren zur Reinigung von Schotter eines Gleises unter Vorwärtsbewegung einer Reinigungsmaschine mit einer Vorfahrtgeschwindigkeit, einer kontinuierlichen Aufnahme des Schotters und Reinigung in einer mit einem hydraulischen Vibrationsantrieb ausgestatteten Siebanlage, wobei der Vibrationsantrieb im Arbeitseinsatz einen Betriebsdruck aufweist, sowie eine Reinigungsmaschine zur Reinigung von Schotter eines Gleises.The invention relates to a method for cleaning ballast of a track below Forward movement of a cleaning machine at a forward speed, a continuous intake of the ballast and cleaning in one with a hydraulic vibratory drive equipped screening plant, the vibratory drive in work use has an operating pressure, and a cleaning machine for cleaning ballast of a track.

Derartige, beispielsweise durch AT 375 982 bekannte Schotterreinigungsmaschinen fördern mit Hilfe einer Räumkette bei kontinuierlicher Arbeitsvorfahrt der Maschine unterhalb eines Gleises befindlichen Schotter in eine Siebanlage. Diese wird durch einen Vibrationsantrieb in Schwingungen versetzt und trennt somit Abraum vom Schotter. Sowohl durch unterschiedliche Abraumanteile als auch durch unterschiedliche Konsistenz des Abraumes kann es zu sprunghaften Änderungen der Siebleistung kommen. Als Folge davon ist die Siebqualität und Siebauslastung in nachteiliger Weise Schwankungen unterworfen.Such, for example, by AT 375 982 known ballast cleaning machines promote with the help of a clearing chain with continuous Arbeitsvorfahrt of the machine below a track located gravel in a sieve. This is going through a vibration drive vibrated and thus separates spoil from the Gravel. Both by different spoilage shares as well as by different Consistency of the overburden can lead to leaky changes in screening performance come. As a result, the screen quality and Siebauslastung in disadvantageous Subject to fluctuations.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Verfahrens zur Reinigung von Schotter eines Gleises, das eine weitgehend konstante Befüllung der Siebanlage ermöglicht. Eine weitere Aufgabe der Erfindung liegt auch in der Schaffung einer Reinigungsmaschine, mit der unter geringem konstruktiven Aufwand eine verbesserte Siebleistung erzielbar ist.The object of the present invention is now to provide a method for cleaning gravel of a track, which is a largely constant filling allows the sieve. Another object of the invention is also in the Creation of a cleaning machine with low design effort an improved screening performance is achievable.

Diese Aufgabe wird mit einem Verfahren zur Reinigung von Schotter eines Gleises dadurch gelöst, daß die Vorfahrtgeschwindigkeit der Maschine in Abhängigkeit von Änderungen des Betriebsdruckes des Vibrationsantriebes derart gesteuert wird, daß zur Erzielung einer konstanten Siebleistung die Vorfahrtgeschwindigkeit bei Sinken des den Vibrationsantrieb steuernden Betriebsdruckes erhöht bzw. bei Ansteigen des Betriebsdruckes reduziert wird.This object is achieved with a method for cleaning ballast of a track solved in that the priority speed of the machine in dependence of Changes in the operating pressure of the vibration drive is controlled so that to achieve a constant screening performance, the forward speed at sinking the operating pressure controlling the vibration drive increases or increases the operating pressure is reduced.

Durch diese Beeinflussung des Fahrantriebes in Abhängigkeit von der sich auf den Betriebsdruck des Vibrationsantriebes auswirkenden Füllmenge der Siebanlage ist auf sehr einfache und wirkungsvolle Weise die Einstellung einer gewünschten konstanten Befüllung der Siebanlage möglich. Daraus resultiert in besonders vorteilhafter Weise eine verbesserte Reinigungsqualität. Außerdem wird eine Überlastung der Siebanlage, wie dies z.B. bei besonders verschmutztem und verklebtem Schotter der Fall sein könnte, zuverlässig ausgeschlossen.Due to this influence of the traction drive as a function of the on the Operating pressure of the vibration drive impacting capacity of the screening plant is in a very simple and effective way setting a desired constant Filling of the sieve plant possible. This results in particular advantageously an improved cleaning quality. In addition, a Overload of the screening plant, as e.g. especially dirty and glued gravel could be the case, reliably excluded.

Die eine Reinigungsmaschine betreffende Aufgabe wird dadurch gelöst, daß eine Regeleinrichtung mit einem einen Betriebsdruck des Vibrationsantriebes erfassenden Druckgeber und einem Stellglied zur Beeinflussung eines auf den Fahrantrieb wirksamen Betriebsdruckes vorgesehen ist.The object of a cleaning machine is achieved in that a Regulating device with an operating pressure of the vibration drive detected Pressure transducer and an actuator for influencing one on the traction drive effective operating pressure is provided.

Ein derartiger Regelkreis ermöglicht bei einem Minimum an konstruktivem Aufwand eine verbesserte Einsatzmöglichkeit, indem einerseits die Siebleistung maximierbar ist und andererseits eine Überlastung der Siebanlage zuverlässig ausschließbar ist. Es erübrigt sich damit auch eine bisher unter Sicherheitsgefährdung von der Bedienungsperson visuell vorgenommene Kontrolle des Befüllungszustandes der Siebanlage. Außerdem ist in besonders vorteilhafter Weise auch ein sehr einfacher nachträglicher Einbau in ältere Maschinen möglich.Such a control circuit allows for a minimum of design effort an improved use, on the one hand, the screening performance maximized is on the other hand, an overload of the screening is reliably excluded. It is therefore unnecessary so far under security risk of the operator Visually made check of the filling condition of the sieve. In addition, in a particularly advantageous manner, a very simple nachträglicher Installation in older machines possible.

Weitere Vorteile der Erfindung ergeben sich aus der Zeichnungsbeschreibung.Further advantages of the invention will become apparent from the description of the drawings.

Im folgenden wird die Erfindung an Hand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben.In the following the invention with reference to an embodiment shown in the drawing described in more detail.

Eine in Fig.1 dargestellte Schotterreinigungsmaschine 1 weist einen über Schienenfahrwerke 2 auf einem Gleis 3 verfahrbaren Maschinenrahmen 4 auf. Die Maschine 1 ist zur Aufnahme von zu reinigendem Schotter 5 mit einer Räumvorrichtung 6 ausgestattet. Diese weist eine durch einen Hydraulikantrieb 7 in Rotation versetzbare, endlose Räumkette 8 auf, mit der unter dem Gleis 3 befindlicher Schotter 5 in eine Siebanlage 9 abwerfbar ist. Diese ist durch einen hydraulischen Vibrationsantrieb 10 in Schwingungen versetzbar. Der aus der Siebanlage 9 kommende gereinigte Schotter 5 ist über ein in Maschinenlängsrichtung verlaufendes Förderband 11 auf das Gleis 3 abwerfbar. Der vom Schotter getrennte Abraum wird über ein weiteres, in Maschinenlängsrichtung verlaufendes Förderband 12 zum vorderen Maschinenende transportiert. Die Maschine 1 wird durch einen Fahrantrieb 13 im Arbeitseinsatz kontinuierlich in der durch einen Pfeil 14 dargestellten Arbeitsrichtung bewegt.A ballast cleaning machine 1 shown in FIG Rail bogies 2 on a track 3 movable machine frame 4 on. The Machine 1 is for receiving to be cleaned ballast 5 with a Broaching device 6 equipped. This has a by a hydraulic drive 7 in Rotation displaceable, endless clearing chain 8 on, with the under the track 3rd located gravel 5 in a sieve 9 is ejected. This is by a hydraulic Vibratory drive 10 vibrated. The from the screening plant 9 coming cleaned ballast 5 is over a running in the machine direction Conveyor belt 11 on the track 3 thrown off. The overburden separated from the gravel is about a further, extending in the machine longitudinal direction conveyor belt 12 for transported front end of the machine. The machine 1 is powered by a traction drive 13 in the working insert continuously in the direction of work shown by an arrow 14 emotional.

Die verschiedenen Antriebe, insbesondere der Fahrantrieb 13 und der Vibrationsantrieb 10, sind über Hydraulikleitungen 15 an ein Hydrauliksystem 16 angeschlossen.The various drives, in particular the traction drive 13 and the Vibration drive 10, are via hydraulic lines 15 to a hydraulic system 16th connected.

Wie aus der schematischen Darstellung in Fig.2 hervorgeht, ist dem Vibrations- und Fahrantrieb 10,13 eine einen Regelkreis bildende Regeleinrichtung 17 zugeordnet. Diese setzt sich im wesentlichen aus einem den Betriebsdruck des Vibrationsantriebes 10 erfassenden Druckgeber 18, einem beispielsweise durch einen Servoantrieb 19 gebildeten Stellglied 21 zur Änderung eines Betriebsdruckes des Fahrantriebes 13 und einem Regler 20 zusammen.As is apparent from the schematic representation in Figure 2, the vibration and Travel drive 10,13 associated with a control loop forming a control loop 17. This consists essentially of an operating pressure of the vibration drive 10 detecting pressure transducer 18, for example by a servo drive 19 formed actuator 21 for changing an operating pressure of the traction drive 13 and a controller 20 together.

Insbesondere durch Verklebung von Abraum mit dem Schotter 5 kommt es zu einer oft sprunghaften Änderung der Siebleistung in der Siebanlage 9. Dies führt zu einer verstärkten Befüllung der Siebanlage 9 und damit verbunden zu einer Erhöhung des Betriebsdruckes für den Vibrationsantrieb 10. Diese Betriebsdruckerhöhung wird durch den Druckgeber 18 dem Regler 20 zugeführt, der durch eine entsprechende Stellgröße das Stellglied 21 bzw. den Servoantrieb 19 derartig beeinflußt, daß der Betriebsdruck für den Fahrantrieb 13 entsprechend reduziert wird. Als Folge davon wird die Vorfahrtgeschwindigkeit der Maschine 1 verringert, so daß durch die Räumkette 8 weniger Schotter 5 aufgenommen und damit auch weniger Schotter 5 der Siebanlage 9 zugeführt wird. Dies führt wiederum zu einer Reduktion der in der Siebanlage 9 befindlichen Schottermasse, bis eine entsprechende Verringerung des Betriebsdruckes des Vibrationsantriebes 10 durch den Druckgeber 18 registriert wird. In weiterer Folge wird durch den Regler 20 wiederum der Betriebsdruck für den Fahrantrieb 13 und damit die Vorfahrtgeschwindigkeit der Maschine 1 erhöht, bis die durch den Regler 20 eingestellte Siebleistung erreicht ist.In particular, by bonding of overburden with the ballast 5, it comes to a often leaps and bounds in the screening performance in the screening plant 9. This leads to a Reinforced filling of the sieve 9 and associated with an increase in the Operating pressure for the vibratory drive 10. This operating pressure increase is supplied by the pressure transducer 18 to the controller 20, by a corresponding Manipulated variable, the actuator 21 and the servo drive 19 influenced in such a way that the Operating pressure for the drive 13 is reduced accordingly. As a consequence of this the speed of advance of the machine 1 is reduced so that through the Clearing 8 less gravel 5 added and thus less gravel. 5 the screen 9 is supplied. This in turn leads to a reduction in the Siebanlage 9 ballast mass, until a corresponding reduction of the Operating pressure of the vibration drive 10 is registered by the pressure transducer 18. As a result, the regulator 20 again the operating pressure for the Traction drive 13 and thus the priority speed of the machine 1 increases until the achieved by the controller 20 Siebleistung is reached.

Für die Einstellung einer bestimmten konstanten Siebleistung der Siebanlage 9 weist der Regler 20 eine Einstellmöglichkeit 22 auf. Damit kann in vorteilhafter Weise unabhängig vom Abraumanteil bzw. dessen Konsistenz eine maximale Siebleistung erzielt werden. Außerdem läßt sich damit eine Überlastung der Siebanlage 9 zuverlässig ausschließen.For setting a certain constant screening capacity of the screen 9 points the controller 20 on a setting 22. This can be independent in an advantageous manner From the spoilage or its consistency a maximum screening performance be achieved. In addition, this can be an overload on the screen 9 reliably exclude.
