Description

Die Erfindung betrifft ein Verfahren zur kontaktfreien Messung eines Querprofils bzw. Abstands von Schienen eines Gleises, insbesondere im Weichenbereich, sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for non-contact measurement of a transverse profile or spacing of rails of a track, in particular in the points area, as well as a device for carrying out the method.

Aus AT 402 953 ist es bereits bekannt, die Spurweite eines Gleises anhand von zwei - jeweils einer Gleisschiene zugeordneten - Abstandsmeßsensoren zu erfassen, die auf einer Radachse eines Schienenfahrzeuges im Bereich zwischen den Schienen gelagert sind.Out AT 402 953 It is already known to detect the track width of a track on the basis of two - each associated with a track rail - Abstandsmeßsensoren which are mounted on a wheel axle of a rail vehicle in the region between the rails.

Gemäß AT 321 346 ist es weiters bekannt, die Schienenköpfe eines Gleises von der Seite her punktförmig anzuleuchten, wobei die Reflexionen der Lichtstrahlen mittels einer in vertikaler Richtung oberhalb der Schiene befindlichen Fotodiodenanordnung erfaßt werden.According to AT 321 346 It is also known to spot-illuminate the rail heads of a track from the side, wherein the reflections of the light beams are detected by means of a photodiode array located in the vertical direction above the rail.

US 3,864,039 offenbart ein Verfahren, bei dem nur der Fuß jeder Schiene beleuchtet wird. Ein oberhalb der Schiene angeordneter Lichtempfänger registriert den vom Schienenkopf geworfenen Schatten, wonach diese Signale in - die Spurweite repräsentierende - Positionsdaten umgewandelt werden. US 3,864,039 discloses a method in which only the foot of each rail is illuminated. A light receiver arranged above the rail registers the shadows cast by the rail head, after which these signals are converted into position data representing the track width.

Das gattungsgemässe Dokument FR-A-2 674 809 offenbart die Messung von Gleisdimensionen mittels einer gleisverfahrbaren Vorrichtung mit einem Lasersender, der einen die Schiene von oben schräg anleuchtenden, aufgefächerten Lichtstrahl erzeugt. Der beleuchtete Teil der Schienenkontur wird anhand einer Matrixkamera aufgezeichnet, und aus dem resultierenden Bild werden die gesuchten Gleisparameter errechnet.The generic document FR-A-2 674 809 discloses the measurement of track dimensions by means of a track-traveling device having a laser transmitter which generates a fanned out light beam obliquely illuminating the rail from above. The illuminated part of the rail contour is recorded using a matrix camera, and the resulting image is used to calculate the track parameters sought.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Verfahrens der gattungsgemäßen Art, das eine schnellere und genauere Ermittlung und Auswertung der für den Weichenzustand maßgeblichen Meßwerte ermöglicht.The object of the present invention is now to provide a method of the generic type, which allows a faster and more accurate determination and evaluation of relevant for the switch state measured values.

Erfindungsgemäß wird diese Aufgabe durch ein Verfahren mit den in Anspruch 1 angeführten kennzeichnenden Merkmalen gelöst.According to the invention, this object is achieved by a method having the characterizing features specified in claim 1.

Mit einem derartigen Verfahren ist es nun möglich, die Messung der verschiedenen Weichenparameter bedeutend rascher und präziser durchzuführen, um insbesondere kritische Weichenbereiche einer exakten Kontrolle unterziehen zu können. Dabei können die vorherrschenden Gegebenheiten und Zustände der Schienen und Weichenelemente zuverlässig dokumentiert (und bei Bedarf auch ausgedruckt) werden. Dadurch ist es in besonders vorteilhafter Weise möglich, das Ausmaß der Abnutzung oder des Verschleißes der Schiene, der Zunge, der Radlenker etc. genau zu eruieren, sodaß auf diesbezügliche Unzulänglichkeiten umgehendst und gezielt reagiert werden kann, bevor die Situation gefährlich bzw. die Sicherheit beeinträchtigt werden kann. Die Messungen können außerdem in überaus hoher Dichte - bezüglich der Vorfahrtsrichtung der das Verfahren ausführenden Maschine - erfolgen, sodaß praktisch eine vollständige Inspektion des Weichenzustandes erzielt werden kann. Überdies kann die Messung sowohl vom Weichenanfang als auch vom Weichenende, also von beiden Seiten her, begonnen werden.With such a method, it is now possible to carry out the measurement of the various course parameters significantly faster and more precisely, in particular to be able to subject critical points areas an exact control. The prevailing conditions and conditions of the rails and switch elements can be reliably documented (and printed if necessary). This makes it possible in a particularly advantageous manner, the extent of wear or deterioration of the rail, the tongue, the Radlenker etc. to accurately determine so that related deficiencies can be reacted immediately and targeted, before the situation dangerous or compromised safety can be. The measurements may also be made at a very high density, with respect to the heading direction of the machine performing the method, so that virtually complete inspection of the turnout condition can be achieved. Moreover, the measurement can be started both from the start of the turnout and from the turnout end, ie from both sides.

Die Erfindung betrifft auch eine Vorrichtung zur kontaktfreien Messung eines Querprofils bzw. Abstands von Schienen eines Gleises, insbesondere im Weichenbereich, gemäß Anspruch 3. Dadurch wird die Möglichkeit geschaffen, die - speziell für die Betriebssicherheit des Gleises besonders wichtigen - Weichendaten und Parameter zuverlässig, präzise und vor allem vollständig zu erfassen.The invention also relates to a device for non-contact measurement of a transverse profile or distance of rails of a track, especially in the switch area, according to claim 3. This creates the possibility, the - especially for the reliability of the track particularly important - turnout data and parameters reliable, precise and, above all, to fully grasp.

Zusätzliche Vorteile und Ausbildungen der Erfindung ergeben sich aus den Unteransprüchen und der Zeichnung.Additional advantages and embodiments of the invention will become apparent from the dependent claims and the drawings.

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

Es zeigen:

  • Fig. 1 einem des eine schematische Draufsicht auf eine Weiche mit einer - auf Gleisfahrzeug angeordneten - Vorrichtung zur Durchführung erfindungsgemäßen Verfahrens,
  • Fig. 2 eine Querschnittsansicht im Bereich eines Radlenkers einer Weichenschiene gemäß dem Schnittpfeil II in Fig. 1, und die
  • Fig. 3 bis 6 jeweils Darstellungen von zu erfassenden Meßgrößen.
Show it:
  • Fig. 1 one of a schematic plan view of a switch with a - arranged on track vehicle - device for carrying out the method according to the invention,
  • Fig. 2 a cross-sectional view in the region of a Radlenkers a switch rail according to the cutting arrow II in Fig. 1 , and the
  • Fig. 3 to 6 in each case representations of measured variables to be detected.

In Fig. 1 ist - als repräsentatives Beispiel - eine typische sogenannte einfache Weiche 1 mit einem Stammgleis 2 und einem Zweiggleis 3 gezeigt, die sich zwischen einem Weichenanfang 4 und einem Weichenende 5 erstreckt. Die Weiche 1 ist im wesentlichen aus Schienen 6, Zungen 7, einem Herzstück 8, Flügelschienen 9 und Radlenkern 10 zusammengesetzt. Auf dem Stammgleis 2 ist ein (lediglich in Umrissen angedeutetes) Gleisfahrzeug 11 zu sehen, auf dem eine Vorrichtung 12 zur Messung des Abstandes der Schienen 6 zueinander bzw. des Querprofiles in verschiedenen Weichenbereichen angeordnet ist. Unter Querprofil sind die aus einem normal zur Schienenlängsrichtung verlaufenden Querschnitt sich ergebenden Schienenumrisse zu verstehen.In Fig. 1 is shown - as a representative example - a typical so-called simple switch 1 with a trunk track 2 and a branch track 3, which extends between a turnout 4 and a turnout 5. The switch 1 is composed essentially of rails 6, tongues 7, a core 8, wing rails 9 and 10 Radlenkern. On the main track 2, a track vehicle 11 (indicated only in outlines) can be seen, on which a device 12 for measuring the distance of the rails 6 from one another or the transverse profile in different points areas is arranged. The term "transverse profile" is understood to mean the rail outlines resulting from a cross section running normal to the rail longitudinal direction.

Die Meßvorrichtung 12 ist auf einem Meßwagen 13 mit einem Rahmen 14 aufgebaut, der auf den Schienen 6 über Spurkranzrollen 15 mit zylindrischen Laufflächen abrollt. Der Meßwagen 13 wird in der Weiche 1 in an sich bekannter Weise an den durchgehenden Schienenstrang angepreßt; in der vorliegenden Zeichnung ist dies die äußere bzw. obere Schiene 6 des Stammgleises 2. Im Bereich oberhalb jeder der vom Meßwagen 13 befahrenen Schienen 6 ist auf dem Rahmen 14 ein Abstandsmeßsensor 16 gelagert, der als berührungslos wirkender und nach unten auf die zugeordnete Schiene 6 gerichteter Laserscanner 17 ausgebildet ist.The measuring device 12 is constructed on a measuring carriage 13 with a frame 14 which rolls on the rails 6 via flanged rollers 15 with cylindrical running surfaces. The measuring carriage 13 is pressed in the switch 1 in a conventional manner to the continuous rail track; in the present drawing, this is the outer or upper rail 6 of the trunk track 2. In the area above each of the rails 6 traveled by the measuring carriage 13 is on the frame 14, a distance measuring sensor 16, which is designed as non-contact and directed down to the associated rail 6 laser scanner 17 is mounted.

Wie nun auch anhand der Fig. 2 besser zu erkennen, emittiert der Laserscanner 17 einen Abtaststrahl 18, der um eine in Längsrichtung des Stammgleises 2 bzw. parallel zur abzutastenden Schiene 6 verlaufende Rotationsachse 19 über einen Scanwinkel α hin- und herbewegt wird. Dadurch wird eine normal zur Gleislängsrichtung verlaufende Abtastebene 20 aufgespannt. Der Laserscanner 17 ist dabei nicht direkt oberhalb der Schiene 6 positioniert, sondern geringfügig in Richtung zur Gleisinnenseite hin versetzt. Das bevorzugte Maß x dieser Versetzung beträgt 22 mm von einem Referenzpunkt A aus gemessen, der sich um den Abstand y (bevorzugt 14 mm) unterhalb der Schienenoberkante (SOK) auf der Fahrkante 21 der Schiene 6 befindet. Daraus ergibt sich, basierend auf der für das Gleis geltenden Standardspurweite von 1435 mm, daß der Abstand der beiden Laserscanner 17 voneinander in Gleisquerrichtung 1391 mm beträgt.Like now also on the basis of Fig. 2 To better detect, the laser scanner 17 emits a scanning beam 18 which is reciprocated about a in the longitudinal direction of the trunk track 2 and parallel to the scanned rail 6 extending axis of rotation 19 over a scan angle α and forth. As a result, a normal to the track longitudinal direction extending scanning plane 20 is spanned. The laser scanner 17 is not positioned directly above the rail 6, but slightly offset in the direction of the track inside. The preferred dimension x of this offset is measured 22 mm from a reference point A, which is located on the trailing edge 21 of the rail 6 by the distance y (preferably 14 mm) below the upper rail edge (SOK). This results in the distance of the two laser scanners 17 from one another in the transverse direction of the track being 1391 mm, based on the standard track width of 1435 mm that applies to the track.

Der vertikale Abstand zwischen Laserscanner 17 und SOK beträgt bevorzugterweise 200 mm. In Verbindung mit der horizontal versetzten Positionierung des Laserscanners 17 und der Größe des Scanwinkels α ergibt sich daraus eine Anordnung, bei der die Abtastebene 20 all jene Bereiche der Schiene 6 und des Radlenkers 10 optimal erfasst, die Verschleiß und Abnützung unterworfen sind. Dies gilt natürlich auch für Weichenbereiche, in denen anstatt eines Radlenkers ein Herzstück, Flügelschienen oder Zungen vorhanden sind.The vertical distance between the laser scanner 17 and SOK is preferably 200 mm. In conjunction with the horizontally offset positioning of the laser scanner 17 and the size of the scan angle α, this results in an arrangement in which the scanning plane 20 optimally detects all those regions of the rail 6 and of the wheel guide 10 which are subject to wear and tear. This of course also applies to points areas in which instead of a Radlenkers a heart, wing rails or tongues are available.

Im Arbeitseinsatz zur kontaktfreien Messung der Weiche 1 wird das Gleisfahrzeug 11 kontinuierlich durch die Weiche verfahren, wobei der Meßwagen 13 über die (zwecks Vermeidung von Höhenfehlern) zylindrisch ausgebildeten Spurkranzrollen 15 auf den Schienen 6 abrollt und am durchgehenden Strang angepreßt wird. Die Messung wird von einem Anfangspunkt - einem sogenannten Synchropunkt - in der Weiche 1 ausgehend durchgeführt. Die beiden Laserscanner 17 scannnen dabei fortlaufend in der jeweiligen Abtastebene 20, während parallel dazu der zurückgelegte Weg anhand eines Wegmeßrades 22 (Fig. 1) registriert wird. Die Fahrgeschwindigkeit kann etwa 1 Meter/Sekunde betragen; im Zungenbereich wird mit etwa der halben Geschwindigkeit gefahren.In work for non-contact measurement of the switch 1, the track vehicle 11 is moved continuously through the switch, wherein the measuring carriage 13 rolls over (in order to avoid height errors) cylindrically shaped flange wheels 15 on the rails 6 and is pressed on the continuous strand. The measurement is from a starting point - A so-called synchro point - carried out starting in the switch 1. The two laser scanners 17 scan continuously in the respective scanning plane 20, while at the same time the distance traveled by means of a Wegmeßrades 22 (FIG. Fig. 1 ) is registered. The driving speed can be about 1 meter / second; in the tongue area is driven at about half the speed.

Zu jedem - durch Auftreffen des Abtaststrahls 18 auf der jeweiligen Schiene 6 bzw. auf einem Weichenelement definierten - Meßpunkt 25 wird nun sowohl der Abstand vom Laserursprung als auch der Winkel des Abtaststrahls 18 als Meßwert in einem Polarkoordinatensystem gemessen. In einer auf dem Gleisfahrzeug 11 vorgesehenen Recheneinheit 23 werden diese Polarkoordinaten der Meßpunkte 25 über ein Programm laufend in kartesische Koordinaten umgerechnet und - in Verbindung mit der kontinuierlichen Wegmessung durch das Wegmeßrad 22 - abgespeichert. Die Meßwerte können parallel dazu auch mit einer Auflösung von bis zu 0,1 mm auf einem Monitor 24 dargestellt werden. Neben den registrierten Meßwerten werden auch die daraus rechnerisch ermittelten, zugehörigen Profile abgespeichert und so ein Querprofil der Weiche 1 erstellt. (Es ist darüberhinaus auch möglich, andere Meßdaten und/oder aufgefundene Mängel bei Bedarf händisch in das Programm der Recheneinheit 23 einzugeben.)For each measuring point 25 defined by the impact of the scanning beam 18 on the respective rail 6 or on a switch element, both the distance from the laser origin and the angle of the scanning beam 18 are measured as a measured value in a polar coordinate system. In a provided on the track vehicle 11 arithmetic unit 23, these polar coordinates of the measuring points 25 are continuously converted via a program in Cartesian coordinates and - in conjunction with the continuous displacement measurement by the Wegmeßrad 22 - stored. The measured values can also be displayed on a monitor 24 with a resolution of up to 0.1 mm in parallel. In addition to the registered measured values, the associated computationally determined profiles are also stored, thus creating a cross-section of the turnout 1. (It is also possible to manually enter other measurement data and / or detected defects as needed in the program of the arithmetic unit 23.)

Für die zum Teil in den Fig. 3 bis 5 schematisch bzw. illustrativ dargestellten Meßgrößen, wie etwa die Spurweite a (Fig. 3), Leitweite b (Fig. 4) oder den Radlenker-Leitflächenabstand c (Fig. 5), gibt es, in Längsrichtung der Weiche 1 gesehen und abhängig von der jeweiligen Weichentype, an den verschiedenen Weichenpunkten oder Meßpunkten 25 die Vorgabe der einzelnen Sollwerte, die in der Recheneinheit 23 vorgespeichert wurden und die nun mit den aktuell gemessenen Meßwerten verglichen werden. Durch die Bestimmung des Ausmaßes der Abweichung von diesen Sollwerten kann der Verschleiß insbesondere der die Weichengeometrie maßgeblich bestimmenden Meßpunkte 25 an den neuralgischen Weichenstellen, die durch eine spezielle Weichentype jeweils exakt definiert sind, präzise und rasch ermittelt werden.For the part in the Fig. 3 to 5 schematically or illustratively illustrated measured quantities, such as the gauge a ( Fig. 3 ), B) b ( Fig. 4 ) or the Radlenker-Leitflächenabstand c ( Fig. 5 ), there are seen in the longitudinal direction of the switch 1 and depending on the respective Weichentype, at the various switch points or measuring points 25, the specification of the individual setpoints, which were pre-stored in the arithmetic unit 23 and which are now compared with the currently measured values. By determining the extent of the deviation from these target values, the wear, in particular that of the switch geometry, can be decisive determining measuring points 25 at the neuralgic switch points, which are each exactly defined by a special Weichentype, are determined precisely and quickly.

Einzuhaltende Toleranzen werden dabei automatisch überprüft. Diese Toleranzen betragen bei den einzelnen Meßgrößen (wie etwa die genannten Größen: Spurweite a, Leitweite b, Radlenker-Leitflächenabstand c, sowie weiters beispielsweise auch Rillenweite, Einlaufweite am Radlenker, Durchlaufrille oder Verschleißzustand der Zunge) jeweils 0,25 mm. Bei den Größen Querhöhe und Verwindung beträgt die Toleranzgrenze 0,5 mm. Bei Überschreitung der zulässigen Toleranzgrenzwerte wird über das Programm ein Einzelfehlerreport erstellt.Adhering tolerances are checked automatically. These tolerances are in the individual measured variables (such as the above variables: track width a, head width b, Radlenker-Leitflächenabstand c, and furthermore also, for example, groove width, inlet width on the wheel, Durchlaufrille or state of wear of the tongue) each 0.25 mm. For the sizes cross height and twist, the tolerance limit is 0.5 mm. If the permissible tolerance limits are exceeded, a single error report is created by the program.

In Fig. 6 ist - als Beispiel eines wichtigen Weichenpunktes - eine am Kopf einer Schiene 6 anliegende Zunge 7 dargestellt, an deren Oberkante ein zu erfassender Meßpunkt 25 liegt. Weitere Beispiele besonders wesentlicher, örtlich bzw. wegabhängig zu erfassender Systempunkte einer Weiche sind etwa der Zungenanfang der abbiegenden Zunge oder der Anfang der (starren oder beweglichen) Herzstückspitze. Damit diese Werte registriert werden können, wird ein Videobild zum Bediener übertragen. Über entsprechende Eventtaster werden die Systempunkte örtlich erfasst.In Fig. 6 is - as an example of an important switch point - a voltage applied to the head of a rail 6 tongue 7, at the upper edge of a detected measuring point 25 is located. Further examples of particularly essential, locally or path-dependent to be detected system points of a switch are about the beginning of the tongue of the bending tongue or the beginning of the (rigid or movable) frog point. To register these values, a video image is transmitted to the operator. The system points are recorded locally via corresponding event buttons.
