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.

Ein derartiges Verfahren ist durch DE-A 23 41 788 bekannt. Dabei wird in einem ersten Arbeitsdurchgang ein relatives Pfeilhöhendiagramm aufgezeichnet, auf dem durch das Personal die Soll-Lage eingezeichnet wird. In einem zweiten Arbeitsdurchgang wird das Gleis unter genauer Beobachtung des Lichtstrahls bezüglich der Seitenlage solange verschoben, bis der Lichtstrahl die eingezeichnete Soll-Lage trifft.Such a method is known from DE-A 23 41 788.

In a driving or working cabin 12 is located a central control device 13.

    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 Steuerund 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. For the detection of track position errors, a track position measuring system 14 is provided, essentially from a laser transmitter 15, one through a Light beam formed measuring line 16, a receiver 17 and a Steuerund Arithmetic unit 18 is formed. The measuring line 16 is replaced by a with the Exit point of the light beam formed measuring reference point A and a second, by the contact with the receiver designed as a line camera 23 17 certain measuring reference point B set.

    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 from the tamping machine 1 movable, flange wheels 19 having and a first feeler 27 forming pregen 20. The receiver 17th is positioned with a Stopfaggreat 8 and lifting and leveling unit 9, via flange rings 21 on track 6 movable and a second Tast organ 28 forming measuring axis 22 is connected.

Die Messungen bestehen aus einer Registrierung der Relativverschiebung 33 zwischen dem im Bereich des Hebe- und Richtaggregates 9 befindlichen Meß-Bezugspunkt B und dem stationären Meß-Bezugspunkt A. 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.In Fig. 3 is formed from a plurality of individual measurements actual position curve 32 of the track 6 shown. The measurements consist of one Registration of the relative displacement 33 between the in the range of Lifting and straightening 9 located measuring reference point B and the stationary Measuring reference point A.

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

    Im folgenden wird der erfindungsgemäße Verfahrensablauf näher beschrieben.The method sequence according to the invention will be 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 track section to be corrected, the preamble 20 of a fixing mechanism 36 of the machine 1 and released onto the Track 6 discontinued. Subsequently, a return of the machine 1 is opposite the direction shown by the arrow 29 until the machine 1 comes to rest on a no longer correctable track section. The tamping unit 8 immediately upstream feeler 28 is on the track 6 set down and serving as a reference rail 5 pressed. Subsequently, the laser transmitter 15 is preferably on the center the receiver 17 targeted and in its position opposite the Vorwagen 20 fixed. At the beginning of the measuring drive of the machine 1 in the direction to Vorwagen 20 it comes according to the track position errors to relative displacements 33 (Fig. 3) between the stationary measuring line 16 and the track following the track line camera 23. These relative displacements 33 are in the control and processing unit 18 in conjunction with a displacement measurement by the distance measuring device 30 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 turn to the beginning of to be corrected Track section is returned, done by the control and computing unit 18 on the basis of the measured actual position curve 32 the Forming a desired position curve 35 and the determination of the corresponding Correction values 34. At the beginning of the work right now becomes immediate before the start of the track position correction by the measuring line 16 automatically that Point of measurement aimed at the line camera 23, which registers during the test drive 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 so long in terms of height and lateral position shifted until that Measuring point is targeted in the two-dimensional line scan camera 23, the the calculated correction value 34 with respect to the actual position results.

    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 is modified in that the laser transmitter 15 with the Measuring axis 22 and the receiver 17 is connected to the pre-carriage 20. In this case, the line camera 23 would be stationary while the measuring line 16 according to the track track relative to the track 6 and the machine. 1 is moved.
