Description

Die Erfindung betrifft eine kontinuierlich verfahrbare Gleisbaumaschine zum kontrollierten Absenken eines Gleises mit Fahrantrieb, einer Steuereinrichtung und einem auf Fahrwerken abgestützten Maschinenrahmen, der mit wenigstens einem durch Antriebe mit einer vertikalen Auflast beaufschlag- und höhenverstellbaren, Vibratoren zur Erzeugung von etwa horizontal und in Maschinenquerrichtung verlaufenden Schwingungen aufweisenden Stabilisationsaggregat verbunden ist, sowie mit einem eine Referenzbasis und eine am Gleis abrollbare Meßradachse aufweisenden Nivellierbezugsystem.The invention relates to a continuously movable track construction machine for the controlled lowering of a track with a traction drive, a control device and a machine frame supported on bogies, which is equipped with at least one vibrator which can be acted upon and height-adjusted by drives with a vertical load, for generating vibrations running approximately horizontally and in the cross-machine direction stabilizing unit is connected, and with a reference base and a rollable measuring wheel axis on the leveling reference system.

Eine derartige, auch als dynamischer Gleisstabilisator bezeichnete Gleisbaumaschine ist durch die US-PS 4,953,467 bereits bekannt und dient zur kontrollierten Absenkung des Gleises nach dem Stopfvorgang, um damit die an sich unvermeidlichen Anfangssetzungen vorwegzunehmen. Die zwischen den Fahrwerken unter dem Maschinenrahmen geführten Stabilisationsaggregate umfassen die Schienenköpfe innen mit acht Spurrollen und außen mit vier Rollentellern. Zwei Stabilisationsaggregate mit synchronisierten Unwuchten bringen das Gleis in horizontale Schwingungen, wobei dieses über vier vertikale, sich am Maschinenrahmen abstützende Antriebe mit einer hohen vertikalen Auflast beaufschlagt wird.Such a track construction machine, also known as a dynamic track stabilizer, is already known from US Pat. No. 4,953,467 and is used for the controlled lowering of the track after the tamping process in order to anticipate the inevitable initial settlements. The stabilization units that run between the trolleys under the machine frame encompass the rail heads on the inside with eight track rollers and on the outside with four roller plates. Two stabilizing units with synchronized imbalances cause the track to vibrate horizontally, whereby a high vertical load is applied to it via four vertical drives supported on the machine frame.

Mit einem derartigen bekannten Gleisstabilisator besteht allerdings das Problem, daß in Gleisabschnitten mit einer Querneigung eine händische Kontrolle der Gleisabsenkung durch die Stabilisationsaggregate durchgeführt werden muß.With such a known track stabilizer, however, there is the problem that manual control of the track lowering must be carried out by the stabilizing units in track sections with a cross slope.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine kontinuierlich verfahrbare Gleisbaumaschine der eingangs beschriebenen Art zu schaffen, mit welcher auch in eine Querneigung aufweisenden Gleisabschnitten eine automatische Kontrolle der Gleisabsenkung durchführbar ist.The object of the present invention is now to provide a continuously movable track construction machine To create the type described above, with which an automatic control of the track lowering can be carried out even in a cross-section having track sections.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß sowohl im Bereich des Stabilisationsaggregates als auch im in Arbeitsrichtung vorderen Endbereich der Maschine jeweils ein Querneigungsmesser angeordnet und ein Zwischenspeicher für die verzögerte Abgabe des vom vorderen, ersten Querneigungsmesser ermittelten Meßwertes vorgesehen ist. Durch diese Ausbildung besteht nunmehr die Möglichkeit, die durch eine Stopfmaschine korrigierte Gleislage unmittelbar vor dem Arbeitseinsatz bezüglich ihrer Querneigung genau zu erfassen und als Soll-Lage dem unmittelbar nachfolgenden kontrollierten Absenkvorgang durch das Stabilisationsaggregat zugrundzulegen. Das heißt, daß die nach dem Stopfvorgang vorliegende genaue gegenseitige Höhenlage der Schienen durch den vorderen Querneigungsmesser im Bereich des vorderen Maschinenabschnittes meßbar und im Zwischenspeicher speicherbar ist. Der gespeicherte Meßwert ist in Abhängigkeit von der Arbeitsgeschwindigkeit der Maschine örtlich verzögert zum Einwirkungsbereich des Stabilisationsaggregates auf den zweiten Querneigungsmesser übertragbar. Damit ist sichergestellt, daß die im Bereich des ersten Querneigungsmessers eruierte Gleisgeometrie im nachfolgenden Einwirkungsbereich des Stabilisationsaggregates genau kopiert und damit die durch eine Stopfmaschine vorher hergestellte genaue Gleislage in unveränderter Genauigkeit beibehalten wird.According to the invention, this object is achieved in that a transverse inclinometer is arranged both in the region of the stabilization unit and in the front end region of the machine in the working direction, and an intermediate memory is provided for the delayed delivery of the measured value determined by the front, first transverse inclinometer. With this design, there is now the possibility of precisely detecting the transverse inclination of the track position corrected by a tamping machine immediately before starting work and of using the stabilization unit as the target position for the immediately following controlled lowering process. This means that the exact mutual height of the rails after the tamping process can be measured by the front cross-meter in the area of the front machine section and can be stored in the buffer. Depending on the operating speed of the machine, the stored measured value can be transferred locally to the area of action of the stabilizing unit on the second bank meter. This ensures that the track geometry determined in the area of the first bank gauge is exactly copied in the subsequent area of action of the stabilization unit and the exact track position previously produced by a tamping machine is maintained with unchanged accuracy.

Eine Weiterbildung der Gleisbaumaschine besteht darin, daß der erste Querneigungsmesser auf der in Arbeitsrichtung vorderen Meßradachse des Nivellierbezugsystems angeordnet ist. Damit ist unter Vermeidung eines zusätzlichen konstruktiven Mehraufwandes eine exakte Erfassung der gegenseitigen Höhenlage der beiden Schienen durchführbar, ohne damit das Nivellierbezugsystem zu beeinflussen. Die den Zwischenspeicher aufweisende Steuereinrichtung ist gemäß einer weiteren Variante der Erfindung mit einer Wegmeßeinrichtung verbunden. Damit besteht die Möglichkeit, die beispielsweise an einer Stelle A ermittelbare Querneigung so lange zwischenzuspeichern, bis das Stabilisationsaggregat an der Stelle A zum Einsatz kommt.A further development of the track construction machine consists in the fact that the first bank gauge is arranged on the measuring wheel axis of the leveling reference system, which is at the front in the working direction. This avoids an exact registration while avoiding additional constructive effort the mutual height of the two rails can be carried out without influencing the leveling reference system. According to a further variant of the invention, the control device having the buffer is connected to a displacement measuring device. There is thus the possibility of temporarily storing the transverse inclination that can be determined at point A until the stabilizing unit is used at point A.

Nach einer anderen Weiterbildung der Erfindung ist sowohl im Bereich beider Maschinenenden als auch im Bereich des Stabilisationsaggregates jeweils ein Querneigungsmesser angeordnet. Durch den in Arbeitsrichtung der Maschine dritten Querneigungsmesser ist einerseits eine genaue Nachkontrolle des abgesenkten Gleisabschnittes durchführbar und die Maschine andererseits auch bedarfsweise in beiden Arbeitsrichtungen einsetzbar.According to another development of the invention, a transverse inclinometer is arranged both in the area of both machine ends and in the area of the stabilization unit. By means of the third cross-section knife in the working direction of the machine, on the one hand an exact rechecking of the lowered track section can be carried out and on the other hand the machine can also be used in both working directions as required.

Schließlich besteht noch eine weitere Variante der Erfindung darin, daß die jeweils im Bereich einer Maschinenlängsseite angeordneten Antriebe zur Übertragung einer vertikalen Auflast auf die Stabilisationsaggregate durch die Steuereinrichtung voneinander unabhängig beaufschlagbar ausgebildet sind. Damit besteht die Möglichkeit, die Bearbeitung bzw. Stabilisierung von Weichen durch Lösung der folgenden Problematik zu verbessern. Im Bereich der Langschwellen weisen die Schienenstränge naturgemäß unterschiedliches Absenkverhalten auf. Dieses führt daher bei konstanter Auflast durch die vertikalen, zwischen Maschinenrahmen und Stabilisationsaggregat befindlichen Antriebe zu einer unterschiedlichen Absenkung beider Schienen. In Verbindung mit einer neuen, voneinander unabhängigen Beaufschlagung der vertikalen Antriebe wird das unterschiedliche Absenkverhalten der einander gegenüberliegenden Schienen durch getrennt gesteuerte seitliche Auflastdrücke automatisch kompensiert. Daher ist ein händisches Nachsteuern überflüssig.Finally, a further variant of the invention consists in the fact that the drives arranged in the area of a machine longitudinal side for transmitting a vertical load to the stabilizing units are designed to be acted upon independently of one another by the control device. It is therefore possible to improve the processing or stabilization of turnouts by solving the following problem. In the area of the long sleepers, the rail tracks naturally have different lowering behavior. Therefore, with constant load, the vertical drives located between the machine frame and the stabilization unit result in a different lowering of both rails. In conjunction with a new, independent loading of the vertical drives, the different lowering behavior of the opposing rails is made possible by separately controlled lateral load pressures automatically compensated. Manual readjustment is therefore unnecessary.

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

Die allgemein auch als Gleisstabilisator bezeichnete Gleisbaumaschine 1 weist einen langgestreckten, endseitig jeweils über ein Fahrwerk 2 auf einem Gleis 3 abgestützten Maschinenrahmen 4 auf, der mit Hilfe eines Fahrantriebes 5 und einer zentralen Energiestation 6 in der durch einen Pfeil 7 dargestellten Arbeitsrichtung verfahrbar ist. In einer der beiden Fahrkabinen 8 befindet sich eine zentrale, einen Zwischenspeicher aufweisende Steuereinrichtung 9.The track construction machine 1, which is also generally referred to as a track stabilizer, has an elongated machine frame 4, which is supported at the ends by a running gear 2 on a track 3 and can be moved in the working direction shown by an arrow 7 with the aid of a travel drive 5 and a central energy station 6. A central control device 9, which has an intermediate store, is located in one of the two cabs 8.

Mittig zwischen den beiden Fahrwerken 2 befinden sich zwei in Maschinenlängsrichtung hintereinander angeordnete und über Zugstangen gelenkig mit dem Maschinenrahmen 4 verbundene Stabilisationsaggregate 10. Zur Aufbringung einer vertikalen Auflast sind zwischen den Stabilisationsaggregaten 10 und dem Maschinenrahmen 4 hydraulische, durch die Steuereinrichtung 9 beaufschlagbare Antriebe 11 vorgesehen. Die Stabilisationsaggregate 10 umfassen die Schienenköpfe jeweils mit vier Spurkranzrollen 12 und zwei an die Schienenaußenseite anlegbaren Rollenteller 13.In the middle between the two undercarriages 2 are two stabilizing units 10 arranged one behind the other in the longitudinal direction of the machine and articulated to the machine frame 4 by means of tie rods. Hydraulic drives 11 which can be acted upon by the control device 9 are provided between the stabilizing units 10 and the machine frame 4 in order to apply a vertical load. The stabilization units 10 each include the rail heads with four flanged wheels 12 and two roller plates 13 that can be placed on the outside of the rail.

Zwei synchronisierte Vibratoren 14 mit bis zu 320 kN Schwungkraft versetzen das Gleis 3 in horizontale und quer zur Maschinenlängsrichtung verlaufende Schwingungen. Deren Frequenz ist von 0 bis 45 Hz verstellbar. Die durch die insgesamt vier Antriebe 11 auf das Gleis 3 einwirkende Auflast beträgt jeweils etwa 100 kN.Two synchronized vibrators 14 with up to 320 kN inertia force the track 3 in horizontal and transverse to the machine longitudinal vibrations. Their frequency is adjustable from 0 to 45 Hz. The load acting on the track 3 through the four drives 11 is approximately 100 kN in each case.

Ein proportional wirkendes Nivellierbezugsystem 15 für das Längsnivellement weist eine über jeden Schienenstrang gespannte und in Maschinenlängsrichtung verlaufende Sehne 16 als Referenzbasis auf, die endseitig jeweils durch höhenverstellbare, auf dem Gleis 3 abrollbare Meßradachsen 17 begrenzt ist. Mit Hilfe einer weiteren, die Sehne 16 kontaktierende Höhenmeßwertgeber aufweisenden Meßradachse 18 ist die Absenkung des Gleises 3 durch entsprechende Regelung der Auflast steuer- und kontrollierbar.A proportionally acting leveling reference system 15 for the longitudinal leveling has a chord 16 stretched over each rail track and running in the machine longitudinal direction as a reference base, which is delimited at the end by height-adjustable measuring wheel axles 17 that can be rolled off the track 3. The lowering of the track 3 can be controlled and controlled by means of a corresponding regulation of the load with the aid of a further measuring wheel axis 18 which contacts the chord 16.

Im in Arbeitsrichtung vorderen Endbereich der Maschine 1 ist ein vom Stabilisationsaggregat 10 in Maschinenlängsrichtung distanzierter Querneigungsmesser 19 vorgesehen, der auf der vorderen Meßradachse 17 des Nivellierbezugsystems 15 befestigt und als elektronisches Präzisionspendel ausgebildet ist. Mit dem vorderen Fahrwerk 2 ist eine auf einer Schiene des Gleises 3 abrollbare Wegmeßeinrichtung 20 mit elektrischem Impulsgeber verbunden. Zwischen den beiden Stabilisationsaggregaten 10 befindet sich noch ein zweiter Querneigungsmesser 21, der auf einer höhenverstell- und auf dem Gleis 3 abrollbaren Meßradachse 22 befestigt ist. Auch die in Arbeitsrichtung hinterste Meßradachse des Nivellierbezugsystems 15 ist mit einem dritten Querneigungsmesser 23 verbunden. Die Querneigungsmesser 19,21,23 sind ebenso wie die Wegmeßeinrichtung 20, die Antriebe 11 und die Vibratoren 14 mit der zentralen Steuereinrichtung 9 verbunden, die zur Zwischenspeicherung des vom vorderen Querneigungsmesser 19 ermittelten Querneigungs-Meßwertes ausgebildet ist.Provided in the front end region of the machine 1 in the working direction is a transverse inclinometer 19 which is distanced from the stabilizing unit 10 in the machine longitudinal direction and is attached to the front measuring wheel axis 17 of the leveling reference system 15 and is designed as an electronic precision pendulum. With the front running gear 2, a position measuring device 20 that can be unrolled on a rail of the track 3 is connected with an electrical pulse generator. Between the two stabilization units 10 there is also a second bank 21, which is fastened on a measuring wheel axis 22 which can be adjusted in height and rolled on the track 3. The rearmost measuring wheel axis of the leveling reference system 15 in the working direction is also connected to a third bank meter 23. The cross-slope meters 19, 21, 23, like the displacement measuring device 20, the drives 11 and the vibrators 14, are connected to the central control device 9, which is designed to temporarily store the cross-slope measurement value determined by the front cross-slope meter 19.

Im Bereich des vorderen Fahrwerkes 2 befindet sich an jeder Maschinenlängsseite ein quer- und höhenverstellbarer Flankenpflug 24, mit dem bedarfsweise Schotter vom Flanken- in den Gleisbereich transportierbar ist. Unmittelbar dahinter ist ein Schotterpflug 25 zur Bearbeitung des Gleisbereiches höhenverstellbar mit dem Maschinenrahmen 4 verbunden. Das in Arbeitsrichtung hintere Ende der Maschine 1 ist durch ein Gelenk mit einem Zusatzrahmen 26 verbunden, dessen hinteres Ende durch ein Fahrwerk 27 am Gleis 3 abstützbar ist. Zur Kontrolle der durch die Stabilisationsaggregate 10 durchführbaren Gleisabsenkung ist ein Kontrollmeßsystem 28 vorgesehen. Eine um eine querverlaufende Achse rotierbare Kehrbürste 29 mit einem Querförderband 30 ist höhenverstellbar am Zusatzrahmen 26 befestigt und dient zur Entfernung von auf den Schwellen liegendem Schotter.In the area of the front undercarriage 2 there is a transverse and height-adjustable side plow 24 on each longitudinal side of the machine, which can be used to transport ballast from the side into the track area. Immediately behind it, a ballast plow 25 for machining the track area is connected to the machine frame 4 in a height-adjustable manner. The rear end of the machine 1 in the working direction is connected by a joint to an additional frame 26, the rear end of which can be supported on the track 3 by a carriage 27. A control measuring system 28 is provided to control the track lowering that can be carried out by the stabilizing units 10. A sweeping brush 29 rotatable about a transverse axis with a transverse conveyor belt 30 is attached to the additional frame 26 in a height-adjustable manner and serves to remove ballast lying on the sleepers.

Im folgenden wird die Funktionsweise der erfindungsgemäßen Maschine näher beschrieben.The mode of operation of the machine according to the invention is described in more detail below.

Sobald der Gleisstabilisator 1 in eine Gleisrampe mit einer sich ständig ändernden Querneigung bzw. Gleisüberhöhung einfährt, wird diese im Bereich der vorderen Meßradachse 17 mit Hilfe des darauf befestigten Querneigungsmessers 19 ermittelt und in der Steuereinrichtung 9 so lange zwischengespeichert, bis die Wegmeßeinrichtung 20 eine der Distanz zwischen dieser und dem zweiten Querneigungsmesser 21 entsprechende Impulszahl abgibt. Das heißt, daß der gespeicherte Meßwert für den zweiten Querneigungsmesser 21 als Soll-Wert zur Verfügung steht, sobald der zweite Querneigungsmesser 21 örtlich jenen Gleisabschnitt erreicht hat, in dem der Meßwert vom vorderen Querneigungsmesser 19 gemessen wurde (siehe Fig.3).As soon as the track stabilizer 1 enters a track ramp with a constantly changing cross slope or track elevation, this is determined in the area of the front measuring wheel axis 17 with the aid of the cross slope meter 19 mounted thereon and temporarily stored in the control device 9 until the distance measuring device 20 detects a distance between this and the second bank 21 gives the corresponding number of pulses. This means that the stored measured value for the second bank gauge 21 is available as a target value as soon as the second bank gauge 21 has locally reached that section of the track in which the measured value was measured by the front bank meter 19 (see FIG. 3).

Im Bereich der Stabilisationsaggregate 10 erfolgt in der bekannten Weise in Zusammenwirkung mit dem Nivellier-Bezugsystem eine kontrollierte Absenkung des Gleises, wobei durch eine entsprechende Änderung der Vorfahrtgeschwindigkeit und/oder der Vibrationsfrequenz und/oder der vertikalen Auf- bzw. Grundlast P die Höhe der Gleisabsenkung veränderbar ist. Im Falle einer Querneigung wird vom vorderen Querneigungsmesser 19 beispielsweise an einer Gleisstelle A (Fig.2) ein entsprechender Meßwert für die Querneigung erfaßt und in der Steuereinrichtung 9 als Sollwert-Vorgabe für die nachfolgende Gleisabsenkung zeitlich so lange zwischengespeichert, bis durch die Wegmeßeinrichtung 20 eine der Distanz zwischen dem vorderen Querneigungsmesser 19 und dem zweiten Querneigungsmesser 21 entsprechende Maschinenvorfahrt registriert wird. Das Nivellierbezugsystem 15 zur Erfassung des Längsnivellements wird jeweils nur auf der Referenzseite, also an der nicht überhöhten Schiene, eingeschaltet.In the area of the stabilization units 10 takes place in the known manner in cooperation with the leveling reference system a controlled lowering of the track, the height of the track lowering being changeable by a corresponding change in the right of way and / or the vibration frequency and / or the vertical load or base load P. In the event of a bank inclination, the front bank inclinometer 19 detects a corresponding measured value for the bank inclination, for example at a track point A (FIG. 2), and temporarily stores it in the control device 9 as a setpoint specification for the subsequent track lowering until a distance is measured by the travel measuring device 20 machine distance corresponding to the distance between the front bank meter 19 and the second bank meter 21 is registered. The level reference system 15 for detecting the longitudinal leveling is only switched on on the reference side, that is, on the rail that is not elevated.

Mit dem nunmehr durch die kontinuierliche Arbeitsvorfahrt auf der Gleisstelle A befindlichen zweiten Querneigungsmesser 21 wird die Querneigung während der durch den Einsatz der Stabilisationsaggregate 10 bewirkten Gleisabsenkung laufend gemessen und als Ist-Wert mit der zwischengespeicherten Sollwert-Vorgabe verglichen. Ist dabei der Ist-Wert größer als der Soll-Wert, wird die vertikale Auflast P auf die Stabilisationsaggregate 10 - durch stärkere Beaufschlagung der Antriebe 11 im Bereich der überhöhten Schiene 31 - entsprechend dem Differenzwert x derart verändert, daß die Querneigung vor dem Arbeitseinsatz der Maschine 1 identisch ist mit der Querneigung nach der kontrollierten Absenkung des Gleises durch die Stabilisationsaggregate 10. Durch den ständigen Vergleich der Querneigung im Arbeitsbereich wird praktisch die vom ersten Querneigungsmesser 19 ermittelte Querneigung für eine kontrollierte Gleisabsenkung kopiert, so daß nach dem Arbeitseinsatz des dynamischen Gleisstabilisators 1 die Gleisgeometrie unverändert beibehalten wird. Mit der strichlierten Linie 32 in Fig.3 ist angedeutet, daß der Differenzwert x auch auf die Antriebe 11 der linken Maschinenseite übertragbar ist, falls die Schiene 33 in einem Rechtsbogen überhöht ist.With the second cross slope meter 21 now located on the track point A due to the continuous work approach, the cross slope is continuously measured during the track lowering caused by the use of the stabilizing units 10 and compared as the actual value with the temporarily stored target value specification. If the actual value is greater than the target value, the vertical load P on the stabilizing units 10 is changed in accordance with the differential value x in such a way that the transverse inclination before the work is carried out by applying more force to the drives 11 in the area of the elevated rail 31 Machine 1 is identical to the cross slope after the controlled lowering of the track by the stabilizing units 10. Due to the constant comparison of the cross slope in the work area, the cross slope determined by the first cross slope meter 19 is practically copied for a controlled track lowering, so that after the work of the dynamic track stabilizer 1 the track geometry remains unchanged. The dashed line 32 in Figure 3 indicates that the Differential value x can also be transferred to the drives 11 on the left machine side if the rail 33 is elevated in a right curve.

Durch den nachfolgenden dritten Querneigungsmesser 21 besteht die Möglichkeit, die Querneigung nach dem Arbeitseinsatz des Gleisstabilisators 1 beispielsweise zur Anlegung eines Protokolles zu vermessen. Für den Fall, daß der Gleisstabilisator 1 keinen Zusatzrahmen 26 aufweist, wäre auch eine Umkehr der Arbeitsrichtung der Maschine 1 möglich, wobei der dritte Querneigungsmesser 23 gemäß Fig.1 und 2 als erster Querneigungsmesser einsetzbar ist. Insbesondere im Bereich von Weichen besteht nunmehr die Möglichkeit, durch entsprechende unterschiedliche Steuerung der in Maschinenquerrichtung einander gegenüberliegenden Antriebe 11 das im Bereich der Langschwellen auftretende unterschiedliche Absenkverhalten automatisch zu kompensieren.The following third bank gauge 21 makes it possible to measure the bank slope after the track stabilizer 1 has been used, for example for the creation of a protocol. In the event that the track stabilizer 1 does not have an additional frame 26, a reversal of the working direction of the machine 1 would also be possible, the third bank meter 23 according to FIGS. 1 and 2 being usable as the first bank meter. In the area of switches in particular, there is now the possibility of automatically compensating for the different lowering behavior occurring in the area of the long sleepers by correspondingly different control of the drives 11 lying opposite one another in the cross-machine direction.
