Description

Die Erfindung bezieht sich auf eine Stopfmaschine zum Unterstopfen von Schwellen eines Gleises, mit auf Schienenfahrwerken verfahrbaren, in Maschinenlängsrichtung hintereinander angeordneten und aneinander gekoppelten Arbeitsmaschinenteilen, einem Versorgungsteil mit einem Maschinenrahmen und einem Arbeitsteil mit einem, zumindest ein höhenverstellbares Stopfaggregat, sowie ein Gleishebe-Richt-Aggregat aufweisenden Maschinenrahmen, wobei sowohl der Versorgungsteil als auch der Arbeitsteil selbstfahrend sind, wobei der Versorgungsteil im Stopfbetrieb kontinuierlich und der Arbeitsteil diskontinuierlich verfahrbar ist, wozu Versorgungsteil und Arbeitsteil miteinander über flexible Versorgungsleitungen, insbesondere für Hydraulik, Pneumatik und Elektrik, verbunden sind und Fahrantriebe von Versorgungsteil und Arbeitsteil entsprechend ansteuerbar sind.The invention relates to a tamping machine for tamping sleepers of a track, with working machine parts that can be moved on rail chassis, are arranged one behind the other in the longitudinal direction of the machine and are coupled to one another, a supply part with a machine frame and a working part with one, at least one height-adjustable tamping unit, and a track lifting straightening Machine frame having a unit, with both the supply part and the working part being self-propelled, with the supply part being able to move continuously in tamping operation and the working part being moveable discontinuously, for which purpose the supply part and working part are connected to one another via flexible supply lines, in particular for hydraulics, pneumatics and electrics, and travel drives from Supply part and working part can be controlled accordingly.

Eine derartige Stopfmaschine offenbart die DE 2818405 A1 . Durch eine Steuervorrichtung ist es möglich, das Steuer- und Kontrollfahrzeug unabhängig von der Vorwärtsbewegung des Arbeitsfahrzeuges, insbesondere auch ständig und kontinuierlich, mit annähernd gleichbleibender Geschwindigkeit entlang des Gleises zu verfahren, sodass die im Steuer- und Kontrollfahrzeug angeordneten Vorrichtungen zur Überwachung, Bedienung und Steuerung der Vorrichtungen und Werkzeuge sowie die Bedienungsperson durch die gegebenenfalls schrittweise Vorwärtsbewegung des Arbeitsfahrzeuges und die auf die Maschine ausgeübten Schläge, Beanspruchungen u.dgl. durch die Werkzeuge bzw. Vorrichtungen nicht beeinflusst wird. Der Antriebsschlupf kann ein exaktes Positionieren des Arbeitsteiles erschweren.Such a tamping machine disclosed DE 2818405 A1 . A control device makes it possible to move the control and monitoring vehicle independently of the forward movement of the work vehicle, in particular constantly and continuously, along the track at an approximately constant speed, so that the devices for monitoring, operation and control arranged in the control and monitoring vehicle of the devices and tools as well as the operator is not influenced by the possibly step-by-step forward movement of the work vehicle and the impacts, stresses, etc. exerted on the machine by the tools or devices. Drive slip can make exact positioning of the working part difficult.

Eine weitere im Arbeitseinsatz kontinuierlich verfahrbare Stopfmaschine ist beispielsweise durch US 6 705 232 bekannt. Der Vorteil der kontinuierlich arbeitenden Stopfmaschinen besteht darin, dass die gesamte Maschine mit ihrer großen Masse nicht bei jeder zu unterstopfender Schwelle gestoppt und anschließend wieder beschleunigt werden muss. Dadurch erhöht sich die Arbeitsgeschwindigkeit der Maschine gegenüber zyklisch arbeitenden Maschinen und außerdem werden die auf den Maschinisten wirkenden Beschleunigungen verringert. Die zyklische Vorfahrt von Schwellenbereich zu Schwellenbereich beschränkt sich bei den bisher bekannten kontinuierlichen Maschinenausführungen auf den die Arbeitsaggregate tragenden, unter der Stopfmaschine angeordneten, Satelliten, der relativ zum Hauptrahmen der Maschine längsverschiebbar ausgebildet ist. Eine solche Maschine ist auch aus der AT401943B und der DE 3409849 A1 bekannt.Another tamping machine that can be continuously moved during work is, for example, by U.S. 6,705,232 known. The advantage of the continuously working tamping machines is that the entire machine with its large mass does not have to be stopped at every threshold to be tamped must then be accelerated again. This increases the working speed of the machine compared to cyclically working machines and also reduces the accelerations acting on the machine operator. In the previously known continuous machine designs, the cyclic advance from threshold area to threshold area is limited to the satellite that carries the working units and is arranged under the tamping machine and is designed to be longitudinally displaceable relative to the main frame of the machine. Such a machine is also from the AT401943B and the DE 3409849 A1 known.

Bekannt ist es auch Anhänger für Stopfmaschinen vorzusehen, auf denen Zusatzaggregate wie dynamische Stabilisieraggregate, Schotterpflug, Schotterkehranlagen, Steilförderband und Silo mit Einschottervorrichtungen etc. aufgebaut sind. Manchmal wird auf Anhängern ein Energie liefernder Dieselmotor aufgebaut, wenn die Hauptmaschine zu schwer ist.It is also known to provide trailers for tamping machines on which additional units such as dynamic stabilizing units, ballast plow, ballast sweeping systems, steep conveyor belt and silo with ballast devices, etc. are constructed. Sometimes a power supply diesel engine is mounted on trailers when the main engine is too heavy.

Werden bestimmte von den Bahndirektionen festgelegte Komfortgrenzwerte oder Sicherheitsgrenzwerte einer geometrischen Gleislage überschritten, dann werden Gleisstopfarbeiten geplant und zeitgerecht durchgeführt. Zur Behebung und Berichtigung dieser geometrischen Gleisfehler kommen Gleisbaumaschinen zum Einsatz.If certain comfort limits or safety limits of a geometric track layout set by the railway management are exceeded, then track tamping work is planned and carried out in a timely manner. Track construction machines are used to eliminate and correct these geometric track errors.

Stopfaggregate fixieren die Lage eines Gleises während einer Instandhaltungsmaßnahme. Dies geschieht über Stopfwerkzeuge, so genannte Stopfpickel, die in den Schotter neben den Schwellen eintauchen und über eine lineare Schließbewegung die durch eine Verdichtschwingung überlagert wird, den Schotter unter der Schwelle verdichten. Das Gleis wird dabei von einer Hebe-Richt-Einrichtung in eine vorgegebene Sollposition gehoben und gerichtet und in dieser während der Stopfung gehalten. Über Messwagen und Steuereinrichtungen wird die Lage des Gleises während der Stopfung gemessen und durch Vergleich mit Sollwerten eines Gleislagecomputers auf Soll gehalten.Tamping units fix the position of a track during a maintenance measure. This is done using tamping tools, so-called tamping picks, which dip into the ballast next to the sleepers and compact the ballast under the sleeper using a linear closing movement that is superimposed by a compaction vibration. The track is lifted and straightened by a lifting and straightening device into a predetermined target position and held in this position during the tamping. The position of the track is measured during the tamping by means of measuring wagons and control devices and is kept on target by comparison with the target values of a track position computer.

Es gibt Stopfmaschinen die auf das Stopfen von Weichen spezialisiert sind, mit teilbaren, quer zur Maschinenlängsrichtung hinsichtlich ihrer Arbeitslage einstellbaren Stopfaggregaten - so genannte Splitheadaggregate, mit Zusatzhebeeinrichtungen für den abzweigenden Strang, mit schwenkbaren Verdichtpickeln, mit einer Verdrehbarkeit der Stopfaggregate um eine Hochachse in der Maschinenquermitte u. dgl. und es gibt Stopfmaschinen die vorzugsweise für das Streckenstopfen gebaut sind. Zudem gibt es Einschwellen- und Mehrschwellenstopfmaschinen. Mehrschwellenstopfmaschinen stopfen in einem Arbeitszyklus mehrere Schwellen auf einmal.There are tamping machines that are specialized in tamping points, with divisible tamping units that can be adjusted transversely to the longitudinal direction of the machine in terms of their working position - so-called split-head units, with additional lifting devices for the branching line, with swiveling compacting picks, with the tamping units being able to rotate about a vertical axis in the transverse center of the machine and the like, and there are tamping machines that are primarily built for line tamping. There are also single-sleeper and multi-sleeper tamping machines. Multi-sleeper tamping machines tamping several sleepers at once in one working cycle.

Bekannte Satellitenrahmen ( US 6 705 232 ) laufen mittels eines Fahrwerks auf den Schienen, welche mit Bremsen und einem auf die Räder wirkenden Antrieb ausgestattet ist. Der Nachteil der bekannten Ausführungen ist, dass der Arbeitssatellit in einer Hauptmaschine geführt wird. Je größer der Satellit ist, wie bei Mehrschwellenstopfmaschinen, umso größer und schwerer ist auch die den Arbeitssatelliten einhausende Hauptmaschine.Known satellite frames ( U.S. 6,705,232 ) run on the rails by means of a chassis, which is equipped with brakes and a drive acting on the wheels. The disadvantage of the known designs is that the working satellite is guided in a main engine. The larger the satellite, as in the case of multi-sleeper tamping machines, the larger and heavier the main engine enclosing the working satellites.

Ein Nachteil dieser Bauart ist, dass die Sehnenteilung der Arbeitssehnen, welche die Gleis-Istgeometrie abtasten und die zwischen einem vorderen, einem mittleren und einem hinteren am Gleis verfahrbaren Messwagen gespannt sind, während des Arbeitens veränderlich ist. Das heißt der vordere und hintere Messwagen, zwischen denen die Messsehne gespannt ist, sind mit dem äußeren kontinuierlich fahrenden Hauptmaschinenrahmen verbunden, während der Messwagen, der die Sensoren zur Abtastung der Gleisgeometrie in Bezug auf die Sehnen trägt, sich auf dem Satelliten befindet, dessen Lage sich bezüglich des Hauptmaschinenrahmens zyklisch ändert.A disadvantage of this design is that the chord pitch of the working chords, which scan the actual track geometry and which are stretched between a front, a middle and a rear measuring carriage that can be moved on the track, is variable during work. That is, the front and rear measurement carriages, between which the measurement chord is stretched, are connected to the outer continuously moving main machine frame, while the measurement carriage, which carries the sensors for scanning the track geometry in relation to the chords, is located on the satellite whose location changes cyclically with respect to the main machine frame.

Da die äußeren Messwagen kontinuierlich fahren und der mittlere Messwagen mit dem Satelliten während der Stopfung stehen bleibt, ändert sich während der Stopfung das Sehnenteilungsverhältnis. Dadurch ändern sich während des Arbeitens die Regelparameter, welche das Gleis auf Nullposition halten müssen und die das Hebe-Richt-Aggregat ansteuern, ständig. Dies führt zu Ungenauigkeiten und schlechteren Ergebnissen der Stopfarbeiten hinsichtlich der zu erzeugenden Soll-Gleisgeometrie.Since the outer measurement carriages move continuously and the center measurement carriage with the satellite remains stationary during tamping, the chord pitch ratio changes during tamping. As a result, the control parameters, which have to keep the track in the zero position and which control the lifting and straightening unit, change constantly while working. this leads to Inaccuracies and poorer results of the tamping work with regard to the target track geometry to be generated.

Durch die Veränderung der Sehnenverhältnisse ändert sich das Gleisgeometriefehler-Verkleinerungsverhältnis, wenn die Maschine im Ausgleichsmodus arbeitet. Das Fehlerverkleinerungsverhältnis hängt vom Verhältnis des langen Sehnenabschnitts zum kurzen Sehnenabschnitt ab. Je größer dieses Verhältnis ist umso mehr werden Gleisfehler verringert. Bei den herkömmlichen kontinuierlichen Stopfmaschinen ändert sich dieses Verhältnis während des Stopfvorganges nachteilig - das Verhältnis wird nämlich mit zunehmender Dauer des Stopfvorganges kleiner.Changing the chord ratios changes the track geometry error reduction ratio when the machine is operating in the compensation mode. The error reduction ratio depends on the ratio of the long chord segment to the short chord segment. The larger this ratio is, the more track errors are reduced. In conventional continuous tamping machines, this ratio changes disadvantageously during the tamping process - namely, the ratio becomes smaller with increasing duration of the tamping process.

Nachteilig ist auch der Mehraufwand an Material und Gewicht, wegen der Größe des äußeren kontinuierlich fahrenden vorderen Maschinenteiles.Another disadvantage is the additional cost of material and weight, due to the size of the outer continuously moving front machine part.

Insgesamt sind dadurch die gesamte notwendige Masse und die Antriebsleistung der Maschine groß.Overall, this means that the total necessary mass and the drive power of the machine are large.

Aus EP 1387003B1 ist bekannt, dass der Fahrantrieb des Satelliten mit Hilfe eines Beschleunigungszylinders unterstützt werden kann. Damit wird zwar die Anfahrverzögerung des Antriebs der Fahrwerke zum Teil kompensiert, aber so ein Beschleunigungszylinder trägt zur Präzision der Positionierung des Satelliten nichts bei. Er weist auch keinen Anteil an der Bremswirkung des Satelliten auf.Out of EP1387003B1 It is known that the propulsion of the satellite can be supported with the help of an acceleration cylinder. This partially compensates for the start-up delay of the landing gear drive, but such an acceleration cylinder contributes nothing to the precision of the positioning of the satellite. It also has no part in the braking effect of the satellite.

Der Erfindung liegt somit die Aufgabe zugrunde, die oben angeführten Nachteile zu vermeiden und eine Stopfmaschine der eingangs geschilderten Art zu schaffen, mit der bessere Ergebnisse hinsichtlich der zu erzeugenden Soll-Gleisgeometrie erreicht werden können.The invention is therefore based on the object of avoiding the disadvantages mentioned above and of creating a tamping machine of the type described at the outset with which better results can be achieved with regard to the desired track geometry to be produced.

Die Erfindung löst die gestellte Aufgabe dadurch, dass der Arbeitsteil mit dem Versorgungsteil zur Unterstützung des diskontinuierlichen Fahrantriebes des Arbeitsteils über mindestens einen hydraulischen Antriebs-/Bremszylinder verbunden ist, der mit einem Positionsgeber zur Erkennung der jeweiligen Kolbenlage im Zylinder ausgestattet ist.The invention solves the task in that the working part is connected to the supply part to support the discontinuous travel drive of the working part via at least one hydraulic drive/brake cylinder is connected, which is equipped with a position sensor for detecting the respective piston position in the cylinder.

Um die Geschwindigkeit und Präzision des zyklisch arbeitenden Arbeitsteils zu unterstützen, ist es vorgesehen, dass der Arbeitsteil mit dem Versorgungsteil zur Unterstützung des diskontinuierlichen Fahrantriebes des Arbeitsteils über mindestens einen hydraulischen Antriebs-/Bremszylinder verbunden ist. Die hydraulischen Zylinder können mit einem Positionsgeber ausgestattet sein, der die jeweilige Kolbenlage im Zylinder an eine Maschinensteuerung übergibt. Dieser Hydrauliktrieb kann sowohl zum Beschleunigen des Arbeitsteils als auch zum Bremsen beim Ausführen der zyklischen Vorfahrt verwendet werden. Der Verlauf der Anfahrrampe und der Bremsrampe kann über Proportionalregelventile und entsprechende Regelelektronik exakt vorgegeben werden. Für den Fall der Überstellfahrt mit gekuppeltem Versorgungs- und Arbeitsteil wird der Hydraulikzylinder vorzugsweise drucklos und damit schwimmend geschaltet.In order to support the speed and precision of the cyclically operating working part, it is provided that the working part is connected to the supply part to support the discontinuous travel drive of the working part via at least one hydraulic drive/brake cylinder. The hydraulic cylinders can be equipped with a position sensor that transmits the respective piston position in the cylinder to a machine control. This hydraulic drive can be used both to accelerate the working part and to brake when performing the cyclic advance. The course of the start-up ramp and the braking ramp can be precisely specified using proportional control valves and corresponding control electronics. In the event of a transfer journey with the supply and working parts coupled, the hydraulic cylinder is preferably depressurized and thus switched to floating.

Der hydraulische Antriebs-/Bremszylinder ist zusätzlich zu den Fahrantrieben von Versorgungs- und Arbeitsteil vorgesehen. Sowohl der Versorgungsteil als auch der Arbeitsteil sind selbstfahrend, wobei der Versorgungsteil im Stopfbetrieb kontinuierlich und der Arbeitsteil diskontinuierlich verfahrbar ist. Um eben die Präzision der gegenseitigen Positionierung von Versorgungs- und Arbeitsteil zueinander bzw. des Arbeitsteiles an einer Arbeitsposition zu verbessern ist die Stopfmaschine zusätzlich zu den Fahrantrieben mit mindestens einem hydraulischen Antriebs-/Bremszylinder ausgestattet, der insbesondere Beschleunigungs- und Bremskräfte überträgt, und damit kürzere Zykluszeiten erlaubt, welche durch einen Antriebsschlupf des zyklisch fahrenden Arbeitsteils nach unten hin beschränkt sind. Dadurch, dass der hydraulischen Antriebs-/Bremszylinder mit einem Positionsgeber zur Erkennung der jeweiligen Kolbenlage im Zylinder ausgestattet ist, ist stets eine genaue Positionierung des Arbeitsteiles bezüglich des Versorgungsteils bzw. an einer Arbeitsposition mit einer entsprechenden Regeleinrichtung möglich.The hydraulic drive/brake cylinder is provided in addition to the travel drives of the supply and working parts. Both the supply part and the working part are self-propelled, whereby the supply part can be moved continuously and the working part can be moved discontinuously during tamping operation. In order to improve the precision of the mutual positioning of the supply and working parts in relation to one another or of the working part in a working position, the tamping machine is equipped with at least one hydraulic drive/brake cylinder in addition to the travel drives, which in particular transmits acceleration and braking forces, and thus shorter ones Cycle times allowed, which are limited downwards by a drive slip of the cyclically moving working part. Because the hydraulic drive/brake cylinder is equipped with a position sensor for detecting the respective piston position in the cylinder, precise positioning of the working part with respect to the supply part or at a working position is always possible with a corresponding control device.

Der Arbeitsteil und der Versorgungsteil sind unabhängig voneinander je mit einem eigenen Fahrantrieb auf einem Gleis verfahrbar. Der Arbeitsteil trägt mindestens ein Stopfaggregat das gesenkt und gehoben werden kann sowie ein Gleishebe-Richtaggregat, eine Arbeitskabine und vorne eine Fahrkabine. Der Versorgungsteil der Maschine trägt die schweren Komponenten, insbesondere den Dieselmotor, die Dieseltanks, Hydrauliktank, Verteilgetriebe und eventuell integrierte andere Arbeitseinheiten, die im kontinuierlichen Mode betrieben werden können wie z.B. dynamische Stabilisieraggregate, Schotterpflüge, Schotterkehranlage, Steilförderband und Silo etc. und eine Fahrkabine hinten.The working part and the supply part can each be moved independently of one another on a track with their own traction drive. The working part carries at least one tamping unit that can be lowered and raised, as well as a track lifting and straightening unit, a work cabin and a driver's cabin at the front. The supply part of the machine carries the heavy components, in particular the diesel engine, the diesel tanks, hydraulic tank, transfer case and possibly other integrated work units that can be operated in continuous mode such as dynamic stabilizing units, gravel plows, gravel sweeping system, steep conveyor belt and silo etc. and a driver's cab at the rear .

Bei einer erfindungsgemäßen Stopfmaschine kann ein großer Teil der Masse eines bei bekannten kontinuierlich arbeitenden Maschinen sonst notwendigen, den Satelliten umgebenden äußeren Maschinenrahmens, entfallen, wodurch eine große Menge an Gewicht eingespart werden kann. Mit dem Arbeitsteil zugeordneten Messwagen sind auch stets konstante Abstände zwischen den Messwagen realisierbar, womit Präzision und Genauigkeit der Berichtigung der Gleisgeometrie zunehmen. Während des Stopfens bleibt das Fehlerverkleinerungsverhältnis nämlich konstant und groß. Dadurch wird eine bessere Fehlerberichtigung durch die Maschine erreicht. Insgesamt wird die Gesamtmasse einer derartigen Maschine gegenüber dem Stand der Technik verringert, was wiederum geringere Herstell- und Betriebskosten und einen kleineren ökologischen Fußabdruck bewirkt.In a tamping machine according to the invention, a large part of the mass of an outer machine frame surrounding the satellite, which is otherwise necessary in known continuously operating machines, can be omitted, as a result of which a large amount of weight can be saved. With the measuring carriage assigned to the working part, constant distances between the measuring carriages can also always be realized, which increases the precision and accuracy of the correction of the track geometry. Namely, during the stuffing, the error reduction ratio remains constant and large. This achieves better error correction by the machine. Overall, the overall mass of such a machine is reduced compared to the prior art, which in turn results in lower manufacturing and operating costs and a smaller ecological footprint.

Es empfiehlt sich zur Messung des Abstands zwischen Arbeitsteil und Versorgungsteil einen Abstandssensor vorzusehen. Über den Abstandssensor, der den Abstand zwischen Versorgungs- und Arbeitsteil misst, können die kontinuierliche Vorfahrgeschwindigkeit und zyklische Vorfahrgeschwindigkeiten automatisch aufeinander abgestimmt geregelt werden. Dies erlaubt ebenfalls die Vermeidung von Kollisionen zwischen Versorgungs- und Arbeitsteil.It is advisable to use a distance sensor to measure the distance between the working part and the supply part. Using the distance sensor, which measures the distance between the supply and working parts, the continuous advance speed and cyclic advance speeds can be automatically coordinated with one another. This also allows collisions between the supply and working parts to be avoided.

Zudem kann der mindestens eine hydraulische Antriebs-/Bremszylinder zur Unterstützung des diskontinuierlichen Fahrantriebes des Arbeitsteils inIn addition, the at least one hydraulic drive/brake cylinder to support the discontinuous travel drive of the working part in

Abhängigkeit des Abstands zwischen Arbeitsteil und Versorgungsteil und der absoluten Positionsdaten, insbesondere GPS-Daten der Stopfmaschine, angesteuert sein.Depending on the distance between the working part and the supply part and the absolute position data, in particular GPS data of the tamping machine, be controlled.

Schwere Maschinenkomponenten, nämlich Antriebsmotor, Treibstofftank, Hydrauliktank und Verteilgetriebe sind vorzugsweise auf dem Versorgungsteil vorgesehen.Heavy machine components, namely drive motor, fuel tank, hydraulic tank and transfer case are preferably provided on the supply part.

Insbesondere kann der Arbeitsteil mit mittels Sehnen verbundenen Messwagen, einem vorderen, einem mittleren und einem hinteren Messwagen, ausgestattet sein, wobei die Sehnen ein fixes Sehnenteilungsverhältnis zwischen den Messwagen (16,11,17) und konstante Sehnenlängen aufweisen.In particular, the working part can be equipped with measuring carriages connected by means of chords, a front, a middle and a rear measuring carriage, the chords having a fixed chord pitch ratio between the measuring carriages (16,11,17) and constant chord lengths.

Je zumindest eines der Laufwerke von Arbeitsteil und Versorgungsteil ist insbesondere mit einem Fahrantrieb ausgestattet. Falls erforderlich können auch zwei oder mehrere Laufwerke mit einem Fahrantrieb ausgestattet sein, falls dies wegen auftretender Brems- bzw. Beschleunigungskräfte nötig ist.At least one of the running gears of the working part and the supply part is in particular equipped with a travel drive. If necessary, two or more running gears can also be equipped with a travel drive if this is necessary because of the braking or acceleration forces that occur.

Für Überstellfahrten werden die beiden Maschinen insbesondere miteinander gekuppelt. Arbeitsteil und Versorgungsteil können dazu mit einer automatischen zentralen Schnellkupplung kuppelbar sein. Alternativ können Arbeitsteil und Versorgungsteil auch mit einer bei Eisenbahnen üblichen Standard-Zug-Druck-Vorrichtung mit Puffern versehen sein.In particular, the two machines are coupled to one another for transfer journeys. Working part and supply part can be coupled with an automatic central quick coupling. Alternatively, the working part and the supply part can also be provided with a standard pull-push device with buffers that is customary on railways.

Günstige Konstruktionsverhältnisse ergeben sich, wenn Arbeitsteil und Versorgungsteil zusammen auf genau vier Schienenfahrwerken verfahrbar sind.Favorable structural conditions result when the working part and the supply part can be moved together on exactly four rail carriages.
