In Arbeitsrichtung vor dieser ist am Maschinenrahmen im Bereich der Schienenbefestigungsmittel eine als Pulsor ausgebildete Abtasteinrichtung angeordnet, die auf die Nähe eines metallischen Objektes, z.B. einer Schienenschraube, anspricht und ein entsprechendes Signal abgibt. Anhand einer Wegmeßeinrichtung wird der von der Maschine zurückgelegte Weg registriert. Die Maschine wird in weiterer Folge unter Berücksichtigung des bekannten Abstandes zwischen Pulsor und Stopfaggregat durch eine Steuereinrichtung derart gestoppt, daß das Stopfaggregat genau über einer Schwelle zu deren Unterstopfung zentriert ist.By US 3,762,333 such a machine is already known, as Tamping machine with a tamping unit designed as a working device is. In front of this is on the machine frame in the field of Rail fastening means designed as a Pulsor scanner arranged close to the vicinity of a metallic object, e.g. one Rail screw, responds and emits a corresponding signal. Based a distance measuring device is the distance traveled by the machine registered. The machine is subsequently considered taking into account the known distance between Pulsor and Stopfaggregat by a Control device stopped so that the tamping unit just above a Threshold to whose constipation is centered.

Bei einer weiteren, gemäß AT 321 347 bekannten Maschine ist ein elektronenoptisches Kontrollorgan in Form einer Fernsehkamera vorgesehen, anhand derer die Bedienungsperson eine individuelle Einstellung des Stopfaggregates auf die Lage der Schwellen vornehmen kann. In another, according to AT 321 347 known machine is an electron-optical Control provided in the form of a television camera, based derer the operator an individual adjustment of Stopfaggregates on the position of the sleepers can make.

Durch US 5 671 679 ist die Verwendung von verschiedenen Arten von Sensoren geoffenbart, mit denen die Lage einer Schwellenplatte oder eines ähnlichen Zielobjektes berührungslos erfaßt werden kann.By US 5,671,679 is the use of various types of sensors disclosed with which the location of a threshold plate or the like Target object can be detected without contact.

Gemäß JP 322707/94 A ist es auch bekannt, anhand einer aus einem Lichtschlitz und einer Kamera gebildeten Bildverarbeitungseinrichtung den Unterschied zwischen Schwellen- und Schotteroberfläche festzustellen und das Absenken von Stopfaggregaten einer Gleisstopfmaschine entsprechend zu steuern.According to JP 322707/94 A, it is also known by means of one of a light slot and a camera-formed image processing device the difference between threshold and ballast surface and determine that Lowering tamping units of a tamping machine according to control.

Die Aufgabe der vorliegenden Erfindung besteht nun in der Schaffung einer gattungsgemäßen Maschine sowie eines Verfahrens, mit der bzw. dem eine verbesserte Erkennung einer Schwellenlage gewährleistet ist.The object of the present invention is now to provide a generic machine and a method, with the or a improved detection of a threshold position is ensured.

Gemäß der Erfindung wird diese Aufgabe mit einer Maschine der gattungsgemäßen Art dadurch gelöst, daß die Abtasteinrichtung als Distanzmesser zur berührungslosen Erfassung von vertikalen Distanzmeßwerten zwischen Abtasteinrichtung einerseits und Schwellen bzw. Schotter des Gleises andererseits ausgebildet ist, und daß die mit dem Distanzmesser verbundene Steuereinheit für eine fortlaufende und aufeinanderfolgende Unterteilung der wegabhängigen Meßstrecke jeweils in einen lediglich geringfügig voneinander abweichende Distanzmeßwerte umfassenden Schwellenerkennungsabschnitt X und einen daran anschließenden, durch eine Folge von sprunghaft veränderten Distanzmeßwerten gekennzeichneten Schottererkennungsabschnitt Y ausgebildet ist.According to the invention, this object is achieved with a machine of the generic type Art solved by the fact that the scanning device as a distance meter for non-contact detection of vertical Distanzmeßwerten between Scanning on the one hand and sleepers or gravel of the track on the other is formed, and that connected to the distance meter Control unit for a continuous and successive subdivision of the path-dependent measuring path in each case only slightly from each other differing distance measurements comprising threshold detection section X and an adjoining, by a series of leaps and bounds changed distance measured marked gravel detection section Y is formed.

Durch diese erfindungsgemäße Lösung ist es möglich, die Schwellenlage zuverlässig und vorallem unabhängig von der Schwellenart zu erkennen, so daß auch ältere Gleise mit einer Vielzahl von verschiedenen Schwellenarten bzw. Schienenbefestigungsarten problemlos abtastbar sind. Durch Anordnung zweier in Maschinenquerrichtung voneinander distanzierter Abtasteinrichtungen besteht auch in vorteilhafter Weise die Möglichkeit, eine Schräglage von Schwellen zu erkennen.By this solution according to the invention, it is possible, the threshold position reliably and especially independent of the type of threshold, so that also older tracks with a variety of different types of sleepers or Schienenbefestigungsarten are easily scanned. By arrangement two spaced apart in the cross-machine direction scanning devices There is also the possibility of an inclined position in an advantageous manner to recognize thresholds.

Weitere vorteilhafte Ausbildungen der Erfindung ergeben sich aus den Unteransprüchen und den Zeichnungen.Further advantageous embodiments of the invention will become apparent from the dependent claims and 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 a shown in the drawing Embodiment described in more detail.

Es zeigen:

  • Fig.2 eine schematische Darstellung einer Abtasteinrichtung mit einer Meßkurve,
  • Fig.3 eine schematisierte Darstellung eines Gleises mit zwei Abtasteinrichtungen sowie entsprechenden Meßkurven, und

    • Show it:
  • 1 shows a simplified side view of a machine with a cyclically usable working device for processing a track,
  • 2 shows a schematic representation of a scanning device with a measuring curve,
  • A schematic representation of a track with two scanning devices and corresponding traces, and
  • 4 shows a schematic representation of parts of the machine.

    • Eine in Fig.1 dargestellte Maschine 1 weist einen auf Schienenfahrwerken 2 abgestützten Maschinenrahmen 3 auf und ist durch einen Fahrantrieb 4 auf einem aus Schwellen 5 und Schienen 6 gebildeten Gleis 7 verfahrbar. Zwischen den Schienenfahrwerken 2 ist eine zyklisch einsetzbare Arbeitsvorrichtung 8 in Form eines Stopfaggregates 9 angeordnet. Diesem ist ein Gleishebeaggregat 10 sowie ein Bezugsystem 11 zugeordnet. In einer durch einen Pfeil 12 dargestellten Arbeitsrichtung vor der Arbeitsvorrichtung 8 befinden sich zwei in Maschinenquerrichtung einander gegenüberliegende Abtasteinrichtungen 13 zur Erkennung der Schwellenlage im Gleis 7. A machine 1 shown in FIG. 1 has a rail carriage 2 supported machine frame 3 and is by a drive 4 on a track formed from sleepers 5 and 6 track 7 movable. Between the rail bogies 2 is a cyclically usable working device 8 arranged in the form of a stuffing 9. This is a track lift unit 10 and a reference system 11 assigned. In one by one Arrow 12 shown working direction in front of the working device 8 two opposite each other in the cross machine direction Scanning 13 for detecting the threshold position in the track 7th

    Für die Messung des von der Maschine 1 am Gleis 7 zurückgelegten Weges ist eine auf der Schiene 6 abrollbare Wegmeßeinheit 14 vorgesehen. Diese steht ebenso wie die Abtasteinrichtung 13 mit einer Steuereinheit 15 in Verbindung.For the measurement of the path traveled by the machine 1 on track 7 a movable on the rail 6 Wegmeßeinheit 14 is provided. This Like the scanning device 13, it is connected to a control unit 15.

    Wie insbesondere aus Fig.2 ersichtlich, ist die Abtasteinrichtung 13 als Distanzmesser 16 für eine berührungslose Messung des vertikalen Abstandes zu der darunterliegenden Schwelle 5 bzw. zu Schotter 17 ausgebildet. Eine in Abhängigkeit des von der Maschine 1 zurückgelegten Weges s erfaßte Meßkurve 18 setzt sich aus einer Vielzahl von Distanzmeßwerten d zusammen.As can be seen in particular from FIG. 2, the scanning device 13 is a distance meter 16 for a non-contact measurement of the vertical distance formed to the underlying threshold 5 or to gravel 17. An in Dependence of the distance traveled by the machine 1 path s detected curve 18 is composed of a plurality of Distanzmeßwerten d.

    Die Meßkurve 18 besteht in abwechselnder Folge aus einem lediglich geringfügig voneinander abweichende Distanzmeßwerte d aufweisenden Schwellenerkennungsabschnitt X und einem Schottererkennungsabschnitt Y zusammen, der sich aus einer Vielzahl von sprunghaft zueinander verändernden Distanzmeßwerten d zusammensetzt. Beginn und Ende des Schwellenerkennungsabschnittes X können relativ einfach unter Zuordnung einer Sprungstelle A bzw. B erkannt werden. Durch Halbierung des Schwellenerkennungsabschnittes X wird ein Zentrierpunkt Zx für die zeitversetzte Zentrierung des Stopfaggregates 9 oberhalb der entsprechenden Schwelle 5 ermittelt.The measuring curve 18 is composed in an alternating sequence of a threshold detection section X having only slightly different distance measurements d and a ballast detection section Y which is composed of a multiplicity of distanced measured values d which change abruptly relative to one another. The beginning and the end of the threshold detection section X can be detected relatively easily by assigning a jump A or B, respectively. By halving the threshold detection section X, a centering point Z x is determined for the time-shifted centering of the tamping unit 9 above the corresponding threshold 5.

    Die innerhalb der beiden Sprungstellen A,B liegenden Distanzmeßwerte d befinden sich mit ihren jeweiligen Maximalwerten innerhalb einer Minimalbandbreite m. Die den Schottererkennungsabschnitt Y definierenden Distanzmeßwerte d liegen mit ihren Maximalwerten deutlich außerhalb der Minimalbandbreite m.The distance measurements d lying within the two discontinuities A, B are within a minimum bandwidth with their respective maximum values m. The defining the ballast detection section Y. Distance measuring values d are clearly outside of their maximum values Minimal bandwidth m.

    Wie in Fig.3 ersichtlich, sind zwei in Maschinenquerrichtung voneinander distanzierte Distanzmesser 16 vorgesehen, um im Rahmen einer Arbeitsvorfahrt der Maschine 1 entlang zweier in Gleislängsrichtung verlaufender Meßlinien 21 die Schwellenlage abzutasten. Damit besteht die Möglichkeit, zwei voneinander unabhängige Meßkurven 18 zu bilden, aus denen schließlich z.B. infolge einer wegversetzten Sprungstelle A eine Schräglage SL einer Schwelle 5 erkennbar ist. Damit können die beiden nachfolgenden, hier nicht näher dargestellten Stopfaggregate 9 unabhängig voneinander jeweils optimal über dem jeweiligen Schwellenabschnitt zur Einleitung des Stopfvorganges zentriert werden.As can be seen in Figure 3, two are spaced apart in the cross-machine direction Distance meter 16 is provided in order to work in progress the machine 1 along two extending in the longitudinal direction of the measuring lines 21 to scan the threshold. This gives the possibility of two from each other to form independent traces 18 from which, finally, e.g. as a result of a staggered discontinuity A a skew SL a threshold 5 can be seen. Thus, the two following, not closer Tamping units 9 shown independently of each other optimally over the respective threshold section for initiating the Stopfvorganges centered become.

    Wie in Fig. 4 schematisch dargestellt, wird in der Steuereinheit 15 unter Registrierung von Sprungstellen A, B die aus einer Vielzahl von Distanzmeßwerten gebildete, wegabhängige Meßkurve 18 in abwechselnd aufeinanderfolgende Schwellenerkennungsabschnitte X und Schottererkennungsabschnitte Y unterteilt, indem beispielsweise die lediglich innerhalb einer Minimalbandbreite m liegenden Distanzmeßwerte d herausgefiltert werden.As schematically shown in Fig. 4, in the control unit 15 under registration jump points A, B from a variety of Distanzmeßwerte formed, path-dependent trace 18 in alternately successive Threshold detection sections X and ballast detection sections Y divided by, for example, the only within a minimum bandwidth m lying Distanzmeßwerte d are filtered out.

    In einer Eingabeeinheit 22 können Grenzwerte zur Definition der Minimalbandbreite m sowie eine Minimal- und Maximalbreite von im Gleis 7 möglicherweise vorkommenden Schwellen 5 zur Definition eines Schwellenakzeptanzbereiches SA eingegeben werden. In einer Prüfeinheit 23 erfolgt eine Plausibilitätsprüfung des zuvor ermittelten Schwellenerkennungsabschnittes X, ob die durch die beiden Sprungstellen A,B definierte Schwellenbreite innerhalb der in der Eingabeeinheit 22 gespeicherten Grenzwerte liegt. Falls diese Prüfung negativ ist, erfolgt die Aktivierung einer akustischen und/oder optischen Warneinrichtung 24, um eine Bedienungsperson auf die unklare Situation aufmerksam zu machen.In an input unit 22, limit values can be used to define the minimum bandwidth m as well as a minimum and maximum width of in track 7 possibly occurring thresholds 5 for defining a threshold acceptance range SA are entered. In a test unit 23 is a Plausibility check of the previously determined threshold detection section X, whether the threshold width defined by the two discontinuities A, B within the limit values stored in the input unit 22. If If this test is negative, the activation of an acoustic and / or optical warning device 24 to alert an operator to the unclear To draw attention to the situation.

    Bei positiver Prüfung wird unter Halbierung der Wegdistanz zwischen den Sprungstellen A, B der Zentrierpunkt Zx ermittelt, gespeichert und wegversetzt für einen automatischen Vorfahrtsstopp der Maschine 1 abgegeben, um schließlich die Stopfaggregate 9 über der jeweiligen Schwelle 5 zu zentrieren.In the case of a positive test, the centering point Z x is determined by halving the path distance between the discontinuities A, B, stored and sent away for an automatic foremost stop of the machine 1, in order finally to center the tamping units 9 above the respective threshold 5.

    Durch die Berechnung der mittleren Schwellenbreite und des mittleren Schwellenabstandes kann das Vorliegen von Doppelschwellen erkannt und angezeigt werden. Durch einen Vergleich der gerechneten mit der tatsächlich gemessenen Vorfahrt wird automatisch ein Korrekturwert berechnet, der die sich während der Arbeit ergebenden unterschiedlichen Verhältnisse (Reibwert Rad/Schiene) in der Berechnung der Sollvorfahrtswerte berücksichtigt. Durch die Möglichkeit, den Bremspunkt der Maschine 1 und das Vorsignal mittels digitaler Einstellmöglichkeit zu verschieben, ist auch eine manuelle Korrektur der Zentrierung der Arbeitsvorrichtung 8 durch die Bedienungsperson möglich. Eventuell im Bereich der Meßlinien 21 liegender Schotter 17 ist durch eine höhenverstellbare Kehreinrichtung 25 (Fig.1) entfernbar.By calculating the mean threshold width and the mean Threshold distance, the presence of double thresholds can be detected and are displayed. By comparing the calculated with the actual measured priority is automatically calculated a correction value, which is the during work resulting different conditions (coefficient of friction Wheel / rail) in the calculation of the desired approach values. Due to the possibility of the braking point of the machine 1 and the distant signal to move by means of digital adjustment, is also a manual Correction of the centering of the working device 8 by the operator possible. Possibly in the range of the measuring lines 21 lying gravel 17 is Removable by a height-adjustable Kehreinrichtung 25 (Figure 1).
