Abstract

The method involves using a measurement system (14) with a measurement line (16) formed by a light beam defined by two reference points (A,B), each formed by a sensing element movable along the track on flanged rollers, whereby the first reference point (A) is in front of the machine and the second (B) between the bogies (2). Relative displacements between the reference points are recorded during a first passage of the machine to form an actual track position graph, from which a desired position graph is derived by forming correction values. The track is raised and packed in the desired position during a second passage by recording the relative displacements of the reference points according to the correction values. An Independent claim is also included for an arrangement for packing a railway track.

Zur Kontrolle der Gleislagekorrektur ist ein Gleislage-Meßsystem mit einer durch einen Lichtstrahl gebildeten Meßlinie in Verwendung. Diese wird durch einen in Arbeitsrichtung der Maschine vorgeordneten ersten Meß-Bezugspunkt und einen nachgeordneten, im Bereich des Gleishebeaggregates positionierten zweiten Meß-Bezugspunkt bestimmt. Die Meßlinie wird in eine vorbestimmte, zur Soll-Lage des Gleises parallele Richtung gebracht. Ein den zweiten Meß-Bezugspunkt bildender Empfänger weist zwei lichtempfindliche Zellen auf, die in vertikaler Richtung um ein bestimmtes Maß voneinander distanziert sind. Der die Meßlinie bildende Lichtstrahl verursacht damit zweierlei Impulse, die zur Steuerung der Gleishebe- und Stopfaggregate einsetzbar sind.Through US 3 545 384 is a tamping machine with one on rail bogies supported machine frame known to carry out Darning work a darning and a lifting and straightening unit are assigned. To check the track position correction, a track position measuring system with a measuring line formed by a light beam in use.

The measuring line is divided into a predetermined brought to the target position of the track parallel direction. A den second measuring reference point forming receiver has two photosensitive Cells that are spaced apart by a certain amount in the vertical direction are. The light beam forming the measuring line thus causes two things Impulses that can be used to control the track lifting and tamping units are.

Gemäß AT 314 580 ist es auch bekannt, Gleisrichtwerkzeuge direkt durch einen mit diesen verbundenen Lasersender zu steuern. Dazu wird vom Sender ein Laserstrahlenbündel auf einen neben dem Gleis befindlichen Festpunkt gerichtet. Das Gleis kann dadurch mit Hilfe der Gleisrichtwerkzeuge so lange verschoben werden, bis das vom Sender ausgehende Strahlenbündel mit einer auf dem Festpunkt befindlichen Kennmarke fluchtet.According to AT 314 580, it is also known to direct track straightening tools to control a laser transmitter connected to this. This is done by the broadcaster a laser beam onto a fixed point next to the track directed. The track can do so with the help of the track straightening tools long shifted until the beam of rays emanating from the transmitter aligned with a mark located on the fixed point.

Gemäß EP 0 401 260 B1 ist eine vor einem Vermessungswagen positionierte Meßlinie bekannt, die durch einen koordinatenmäßig bekannten Meß-Bezugspunkt und einen weiteren, im Zentrum einer durch eine Vielzahl von Fotozellen gebildeten Empfängereinrichtung positionierten Meß-Bezugspunkt bestimmt wird. In Verbindung mit einer Entfernungsmeßeinrichtung ist die Abweichung des zweiten Meß-Bezugspunktes von der Soll-Lage genau eruierbar.According to EP 0 401 260 B1, one is positioned in front of a survey car Known measuring line by a coordinate reference point known in terms of coordinates and another, at the center of one through a multitude of photocells Formed receiver device positioned measuring reference point determined becomes. The deviation is in connection with a distance measuring device of the second measuring reference point can be exactly determined from the target position.

Ein weiteres, einer Gleislage-Korrekturmaschine vorgeordnetes Meß-Bezugsystem mit einer durch zwei Bezugspunkte gebildeten Meßlinie ist durch AT 328 490 bekannt.Another measuring reference system upstream of a track correction machine with a measuring line formed by two reference points is through AT 328 490 known.

Die Aufgabe der vorliegenden Erfindung liegt in der Schaffung eines Verfahrens der gattungsgemäßen Art, mit dem insbesondere kurze Gleisabschnitte optimal in eine Soll-Lage bringbar sind.The object of the present invention is to provide a method of the generic type with which, in particular, short track sections can be optimally brought into a target position.

Erfindungsgemäß wird diese Aufgabe mit einem Verfahren der gattungsgemäßen Art dadurch gelöst, daß

  • a) in einer ersten Maschinenvorfahrt Relativverschiebungen zwischen den beiden Meß-Bezugspunkten unter Bildung einer Ist-Lagekurve des Gleises registriert werden,
  • b) aus der Ist-Lagekurve unter Bildung von Korrekturwerten eine Soll-Lagekurve des Gleises errechnet wird, und
  • c) in einer zweiten Maschinenvorfahrt das Gleis unter Registrierung der Relativverschiebungen zwischen den beiden Meß-Bezugspunkten entsprechend den ermittelten Korrekturwerten in die Soll-Lage angehoben und unterstopft wird.
    • According to the invention, this object is achieved with a method of the generic type in that
  • a) relative shifts between the two measuring reference points are registered in a first machine approach, forming an actual position curve of the track,
  • b) a target position curve of the track is calculated from the actual position curve with formation of correction values, and
  • c) in a second machine approach, the track is raised and stuffed into the target position by registering the relative displacements between the two measuring reference points in accordance with the determined correction values.

    • Dieses Verfahren ermöglicht bei minimalen Rüstarbeiten eine sehr rasche Erfassung der Gleis-Ist-Lage sowie eine genaue Durchführung von Korrekturarbeiten. Die Gleisverschiebungen können in vorteilhafter Weise während der Arbeitsvorfahrt durch Registrierung der Relativverschiebung zwischen den beiden Meß-Bezugspunkten präzise erfaßt werden, so daß die Gleislage nach erfolgter Lagekorrektur genau den errechneten Soll-Werten entspricht. Ein besonderer Vorteil dieser Direktsteuerung des zweiten Meß-Bezugspunktes und damit auch des Gleishebe- und Richtaggregates ist darin zu sehen, daß die Gleislagekorrektur im zu korrigierenden Gleisabschnitt ohne zeitaufwendige Rampenbildung zum anschließenden, unveränderten Gleisabschnitt durchführbar ist.This process enables very quick set-up work Acquisition of the actual track position as well as an exact implementation of correction work. The track shifts can advantageously during the right of way by registering the relative shift between the two measuring reference points can be detected precisely, so that the track position after the position has been corrected corresponds exactly to the calculated target values. A particular advantage of this direct control of the second measuring reference point and thus also the track lifting and straightening unit is closed see that the track position correction in the track section to be corrected without time-consuming ramp formation to the subsequent, unchanged track section is feasible.

    Weitere Vorteile der Erfindung ergeben sich aus den weiteren Ansprüchen und den Zeichnungen.Further advantages of the invention result from the further claims and the drawings.

    Zur Erfassung von Gleislagefehlern ist ein Gleislage-Meßsystem 14 vorgesehen, das im wesentlichen aus einem Lasersender 15, einer durch einen Lichtstrahl gebildeten Meßlinie 16, einem Empfänger 17 und einer Steuer- und Recheneinheit 18 gebildet ist. Die Meßlinie 16 wird durch einen mit dem Austritt des Lichtstrahls gebildeten Meß-Bezugspunkt A und einen zweiten, durch den Kontakt mit dem als Zeilenkamera 23 ausgebildeten Empfänger 17 bestimmten Meß-Bezugspunkt B festgelegt. A track position measuring system 14 is provided for detecting track position errors. that essentially consists of a laser transmitter 15, one by one Beam of light formed measuring line 16, a receiver 17 and a control and Computing unit 18 is formed. The measuring line 16 is marked with a Exit of the light beam formed measuring reference point A and a second, by contact with the receiver designed as a line camera 23 17 determined measurement reference point B.

    Der Sender 15 des Gleislage-Meßsystems 14 befindet sich auf einem unabhängig von der Stopfmaschine 1 verfahrbaren, Spurkranzrollen 19 aufweisenden und ein erstes Tastorgan 27 bildenden Vorwagen 20. Der Empfänger 17 ist mit einer zwischen Stopfaggreat 8 sowie Hebe- und Richtaggregat 9 positionierten, über Spurkranzrollen 21 am Gleis 6 verfahrbaren und ein zweites Tastorgan 28 bildenden Meßachse 22 verbunden. Die Meßachse 22 bildet auch einen Teil eines weiteren, durch Meßachsen 24 und eine Stahlsehne 25 gebildeten Bezugsystems 26. Die bezüglich der Arbeitsrichtung (Pfeil 29) vordere Meßachse 24 des Bezugsystems 26 ist mit einer Wegmeßeinrichtung 30 verbunden.The transmitter 15 of the track position measuring system 14 is located on an independent movable from the tamping machine 1, having flanged wheels 19 and a first carriage 20 which forms a scanning element 27. The receiver 17 is positioned between a tamping unit 8 and a lifting and straightening unit 9, Movable via flanged wheels 21 on track 6 and a second one Probe 28 forming measuring axis 22 connected.

    In Fig. 2 ist ersichtlich, daß die durch die beiden Meß-Bezugspunkte A und B bestimmte optische Meßlinie 16 seitlich neben der Maschine positioniert ist. Zu diesem Zweck ist die Zeilenkamera 23 des hinteren Tastorganes 28 in Maschinenquerrichtung seitlich über ein Maschinenprofil 31 hinausragend ausgebildet.In Fig. 2 it can be seen that the by the two measuring reference points A and B certain optical measuring line 16 positioned to the side of the machine is.

Die Relativverschiebungswerte sind somit jeweils durch den Abstand zwischen der stationären Meßlinie 16 und dem jeweiligen Meßpunkt auf der entlang des Gleises 6 geführten Zeilenkamera 23 definiert. Die zu den Relativverschiebungen 33 jeweils addierten Korrekturwerte 34 ergeben eine Soll-Lagekurve 35 des Gleises 6. Parallel zur Messung wird der von der Maschine 1 zurückgelegte Weg s durch die Wegmeßeinrichtung 30 registriert.3 shows an actual position curve formed from a large number of individual measurements 32 of the track 6 shown. The measurements consist of a Registration of the relative displacement 33 between that in the area of Lifting and straightening unit 9 located reference point B and the stationary Measuring reference point A.

Parallel to the measurement the path s traveled by the machine 1 through the path measuring device 30 registered.

    Im folgenden wird der erfindungsgemäße Verfahrensablauf näher beschrieben.The process sequence according to the invention is described in more detail below.

    Nach Überfahren des zu korrigierenden Gleisabschnittes wird der Vorwagen 20 von einem Fixiermechanismus 36 der Maschine 1 gelöst und auf das Gleis 6 abgesetzt. Anschließend erfolgt eine Rückfahrt der Maschine 1 entgegen der durch den Pfeil 29 dargestellten Arbeitsrichtung, bis die Maschine 1 auf einem nicht mehr zu korrigierenden Gleisabschnitt zu stehen kommt. Das dem Stopfaggregat 8 unmittelbar vorgeordnete Tastorgan 28 wird auf das Gleis 6 abgesetzt und gegen eine als Bezugsstrang dienende Schiene 5 gedrückt. Anschließend wird der Lasersender 15 vorzugsweise auf das Zentrum des Empfängers 17 angepeilt und in seiner Lage gegenüber dem Vorwagen 20 fixiert. Bei der nun beginnenden Meßfahrt der Maschine 1 in Richtung zum Vorwagen 20 kommt es entsprechend den Gleislagefehlern zu Relativverschiebungen 33 (Fig. 3) zwischen der stationären Meßlinie 16 und der dem Schienenverlauf folgenden Zeilenkamera 23. Diese Relativverschiebungen 33 werden in der Steuer- und Recheneinheit 18 in Verbindung mit einer Wegmessung durch die Wegmeßeinrichtung 30 gespeichert.After passing over the section of track to be corrected, the front carriage becomes 20 released from a fixing mechanism 36 of the machine 1 and on the Track 6 set off. The machine 1 is then reversed the working direction shown by arrow 29 until the machine 1 comes to rest on a track section that can no longer be corrected. The feeler 28 immediately upstream of the tamping unit 8 is opened the track 6 is set down and against a rail 5 serving as a reference track pressed. Then the laser transmitter 15 is preferably on the center the receiver 17 targeted and in its position in relation to the front car 20 fixed. When the measuring run of the machine 1 now begins in the direction to the carriage 20 there are relative shifts in accordance with the track position errors 33 (Fig. 3) between the stationary measuring line 16 and the line camera 23 following the course of the rail. These relative displacements 33 are in the control and computing unit 18 in connection with a distance measurement by the distance measuring device 30 is stored.

    Während die Stopfmaschine 1 wiederum zum Anfang des zu korrigierenden Gleisabschnittes zurückgefahren wird, erfolgt durch die Steuer- und Recheneinheit 18 unter Zugrundelegung der aufgemessenen Ist-Lagekurve 32 die Bildung einer Soll-Lagekurve 35 sowie die Ermittlung der entsprechenden Korrekturwerte 34. Bei der nun beginnenden Arbeitsvorfahrt wird unmittelbar vor Beginn der Gleislagekorrektur durch die Meßlinie 16 automatisch jener Meßpunkt an der Zeilenkamera 23 angepeilt, der bei der Meßfahrt registriert und zur Bildung der Ist-Lagekurve 32 herangezogen wurde. Zur Durchführung der Gleislagekorrektur wird nun das Gleis 6 durch das Hebe- und Richtaggregat 9 so lange bezüglich Höhen- und Seitenlage verschoben, bis jener Meßpunkt in der zweidimensionalen Zeilenkamera 23 angepeilt wird, der den errechneten Korrekturwert 34 in bezug auf die Ist-Lage ergibt.While the tamping machine 1 in turn to the beginning of the to be corrected Track section is moved back takes place by the control and computing unit 18 on the basis of the measured actual position curve 32 Formation of a target position curve 35 and the determination of the corresponding Correction values 34. When the right of way begins, immediate before the start of the track position correction by the measuring line 16 that automatically Aimed at the measuring point on the line camera 23, which registers during the measurement run and was used to form the actual position curve 32. To carry out the track position correction is now the track 6 by the lifting and straightening unit 9 shifted in terms of height and lateral position until that Measuring point is aimed in the two-dimensional line camera 23, the gives the calculated correction value 34 in relation to the actual position.

    Es versteht sich von selbst, daß das erfindungsgemäße Verfahren mit dem selben Ergebnis insofern abwandelbar ist, daß der Lasersender 15 mit der Meßachse 22 und der Empfänger 17 mit dem Vorwagen 20 verbunden wird. In diesem Falle wäre die Zeilenkamera 23 stationär, während die Meßlinie 16 entsprechend dem Gleisverlauf relativ zum Gleis 6 bzw. zur Maschine 1 bewegt wird.It goes without saying that the inventive method with the The same result can be modified in that the laser transmitter 15 with the Measuring axis 22 and the receiver 17 is connected to the front carriage 20. In this case the line camera 23 would be stationary while the measuring line 16 corresponding to the track course relative to track 6 or to machine 1 is moved.
