Description
Die Erfindung betrifft eine Maschine zur Bearbeitung einer Schotterbettung bzw. eines Planums für ein aus Schienen und Schwellen gebildetes Gleis, mit einem durch Schienenfahrwerke am Gleis kontinuierlich verfahrbaren Maschinenrahmen und einer zwischen zwei Schienenfahrwerken angeordneten Gleishebevorrichtung, die zur Anhebung des Gleises durch Antriebe höhenverstellbar mit dem Maschinenrahmen verbunden ist, und ein - um eine in Maschinenquerrichtung ausgerichtete Achse rotierbares - Rollelement zur Auflage der Schwellen des Gleises aufweist. The invention relates to a machine for processing a ballast bed or of a formation for a track formed by rails and sleepers, with one Machine frames that can be moved continuously thanks to rail bogies on the track and a track lifting device arranged between two rail bogies, those for lifting the track by drives adjustable in height with the machine frame is connected, and a - around a cross machine direction Axis rotatable - rolling element for supporting the sleepers of the track.
Eine derartige Maschine ist bereits durch US-A-1,899,874 bekannt, wobei in Verbindung mit einer Schotterreinigung das Gleis kontinuierlich mit Hilfe der Gleishebevorrichtung von der Schotterbettung abgehoben wird. Die Gleishebevorrichtung setzt sich aus einer Vielzahl von in Maschinenlängsrichtung hintereinander angeordneten Rollelementen zusammen, die durch Positionierung unterhalb des Gleises zur Abstützung der Schwellen dienen. Such a machine is already known from US-A-1,899,874, in connection with a ballast cleaning the track continuously with the help of the track lifting device is lifted off the ballast bed. The track lifting device sets are made up of a large number of arranged one behind the other in the machine longitudinal direction Rolling elements put together by positioning them below the track for support serve the thresholds.
Durch die CH-A-291134 ist ebenfalls eine Maschine zur Schotterreinigung bekannt, wobei die Gleishebevorrichtung aus zwei in Maschinenquerrichtung voneinander distanzierten, kufenartigen Gleitkörpern gebildet ist, die unterhalb des Gleises zur Abstützung desselben positioniert sind. A machine for ballast cleaning is also known from CH-A-291134, the track lifting device consisting of two spaced apart in the cross-machine direction, skid-like sliding bodies is formed, which is below the track for support are positioned.
Eine weitere Maschine ist bereits aus der US-A-4,479,439 bekannt und dient zum Auswechseln einer Gleisschotterbettung bei gleichzeitiger Einbringung einer Planumsschutzschicht. Der kontinuierlich verfahrbare Maschinenrahmen ist endseitig auf Schienenfahrwerken abgestützt und mit weiteren Transportfahrzeugen zu einer Anlage gekuppelt, wobei eines der Fahrwerke zwecks Vergrößerung der Spannweite zwischen den Auflagerpunkten des Maschinenrahmens anhebbar ist. Anhand einer etwa mittig zwischen diesen Punkten höhenverstellbar mit dem Maschinenrahmen verbundenen Gleishebevorrichtung wird das Gleis angehoben, um unterhalb der Schwellen genügend Raum für die Bettungsbearbeitungsaggregate zu schaffen, die aus einer Räumkette zum Freilegen des Planums sowie höhenverstellbaren Planiereinrichtungen zum Ebnen und Verdichten von auf das Planum abgeworfenem Sand und Schotter bestehen. Die Gleishebevorrichtung weist zur Führung bzw. Halterung des Gleisrostes in der gewünschten Höhe seitlich verschwenkbare Rollhebeteller auf, die zangenförmig von beiden Seiten unter den Schienenkopf eingeschwenkt werden und kontinuierlich mit den Schienen in Eingriff verbleiben. Bei gegebenenfalls auftretenden Änderungen des Schienenquerschnitts, wie beispielsweise während des Überfahrens eines Schienenstoßes, kann allerdings der formschlüssige Kontakt dieser sogenannten Rollzangen mit dem Schienenkopf gestört werden und dadurch die sichere Abstützung des Gleises nicht kontinuierlich gewährleistet bleiben. Another machine is already known from US-A-4,479,439 and is used for Replacing a track ballast bed with simultaneous application of a formation protection layer. The continuously movable machine frame is at the end supported on rail bogies and with other transport vehicles to one System coupled, one of the trolleys for the purpose of increasing the span can be raised between the support points of the machine frame. Based one height adjustable approximately midway between these points with the machine frame connected track lifting device, the track is raised to below the thresholds to create enough space for the bed processing units, that from a clearing chain to expose the formation as well as height-adjustable grading devices for leveling and compacting what has been dropped on the formation There is sand and gravel. The track lifting device has for guidance or mounting of the track grate can be swiveled laterally at the desired height on, which is swung in like pliers from both sides under the rail head and remain in constant engagement with the rails. If necessary occurring changes in the rail cross section, such as when driving over a rail joint, however, the positive one Contact of these so-called roller tongs with the rail head disturbed are and thus the continuous support of the track is not guaranteed stay.
Aus der US-A-3,179,062 ist eine weitere Maschine zur Bearbeitung einer Gleisbettung bekannt, die im wesentlichen aus einer unterhalb des Gleisrostes in Gleislängsrichtung keilförmig vorschiebbaren, einen Rahmen aufweisenden Vorrichtung besteht. Diese Vorrichtung stützt sich über höhenverstellbar mit dem Rahmen verbundene, angetriebene Raupenfahrwerke auf der Schotter- oder Planumsoberfläche ab, welche von am vorderen Ende der Vorrichtung befindlichen Räumwerkzeugen planiert wird. Die vertikale Abstützung bzw. Distanzierung des Gleisrostes von der Gleisbettung erfolgt durch zwei sich in Maschinenlängsrichtung erstreckende Raupenketten, die im Bereich unterhalb der Schienen an der Oberseite des Rahmens der Vorrichtung angeordnet sind und gegen die Schwellenunterseiten pressen bzw. auf diesen abrollen, während die Vorrichtung durch die Gleisbettung vorgetrieben wird. Ein oberhalb der Vorrichtung auf dem Gleis verfahrbares Fahrzeug ist mit einer Kraftquelle und Steuereinheit ausgestattet und wird mit der Vorrichtung über eine an der Maschinenlängsseite angebrachte Verbindung mitbewegt. Dabei wird auch das Gewicht des Fahrzeuges über die Raupenfahrwerke auf die Bettung übertragen. Ein derartiger Maschineneinsatz erfordert jedoch eine sehr hohe Gleisanhebung und verursacht damit eine insbesondere bei schweren Schienen unzulässige Biegebelastung. From US-A-3,179,062 is another machine for processing a track bed known, essentially from a below the track grate in the longitudinal direction there is a wedge-shaped, device having a frame. This device is supported by height-adjustable, connected to the frame driven crawler tracks on the gravel or formation surface, which leveled by broaching tools located at the front end of the device becomes. The vertical support or spacing of the track grate from the track bed takes place by two caterpillar tracks extending in the machine longitudinal direction, those in the area below the rails at the top of the frame of the device are arranged and press against the underside of the threshold or on this unroll while the device is being driven through the track bed. A Vehicle that can be moved on the track above the device is with a power source and control unit and is equipped with the device via a Moved connection along the machine side. This also includes the weight of the vehicle on the crawler tracks on the bedding. A Such use of machinery, however, requires a very high track lift and causes an impermissible bending load, especially with heavy rails.
Eine ähnliche Vorrichtung zum Planieren einer Schotterbettoberfläche unterhalb eines Gleisrostes ist in der CA-A-523,843 beschrieben und weist einen als horizontale Platte ausgebildeten, schlittenartigen Planierschild auf, der hinter einer auf dem Gleis fahrenden Maschine wie ein Keil zwischen Gleis und Bettung eingeschoben und nachgezogen wird. Um das Gleis von der Bettung abzuheben und hochzupressen, sind auf der Schildoberseite zwei lange Reihen von Rollen montiert, auf denen jeweils eine endlose Kette in Gleislängsrichtung angeordnet ist und im Bereich unterhalb der Schienen auf der Schwellenunterseite abrollt. A similar device for leveling a ballast bed surface below a track grate is described in CA-A-523,843 and has one as horizontal Plate-trained, sled-like dozer blade, which behind one on the Rail-running machine inserted like a wedge between the track and the ballast and is tightened. In order to lift the track from the bed and to push it up, two long rows of rollers are mounted on the top of the shield, on which an endless chain is arranged in the longitudinal direction of the track and in the area below the rails roll on the underside of the sleeper.
Die Aufgabe der vorliegenden Erfindung besteht nun in der Schaffung einer Maschine der eingangs genannten Art, mit der das Gleis unabhängig von Schienenunregelmäßigkeiten, wie z. B. Schienenstößen, sicher und zuverlässig anhebbar ist. Diese Aufgabe wird mit einer Maschine der gattungsgemäßen Art dadurch gelöst, daß die Gleishebevorrichtung einen senkrecht zur Maschinenlängsrichtung verlaufenden, länger als eine Schwellenlänge ausgebildeten Tragkörper aufweist, der im Arbeitseinsatz mit den Antrieben eine das Gleis in Maschinenquerrichtung umfassende, ausschließlich am Maschinenrahmen abgestützte Baueinheit bildet, wobei der Tragkörper im Bereich beider bezüglich der Maschinenquerrichtung einander gegenüberliegenden Enden mit Stützen verbunden ist, die in einer in Maschinenlängsrichtung von den Antrieben distanzierten, gemeinsamen Auslenkstelle um ein allseitig wirksames gelenk verschwenkbar mit dem Maschinenrahmen verbunden sind, und daß den Stützen ein am Maschinenrahmen angelenkter Schwenkantrieb zugeordnet ist. The object of the present invention is to create a machine of the type mentioned at the beginning, with which the track is independent of rail irregularities, such as B. rail joints can be lifted safely and reliably. This object is achieved with a machine of the generic type in that that the track lifting device runs perpendicular to the machine longitudinal direction, longer than a threshold length formed support body, which in Work deployment with the drives, which encompass the track in the cross-machine direction, forms only a structural unit supported on the machine frame, being the supporting body in the area of both opposite each other with respect to the cross machine direction Ends connected to supports in a machine longitudinal direction a common deflection point distanced from the drives universal joint swiveling with the machine frame are connected, and that the supports one on the machine frame hinged rotary actuator is assigned.
Mit einer derartigen Gleishebevorrichtung sind die Gleishebekräfte von den Antrieben auf die Schwellenunterseiten übertragbar, ohne daß es dazu einer Kontaktnahme mit den Schienen bedarf. Folglich wird die Sicherheit der Gleisabstützung auch im Falle von den Schienenquerschnitt verändernden Schienenstoßverbindungen od. dgl. in keiner Weise beeinträchtigt. Da sich die Gleishebevorrichtung über die Antriebe ausschließlich auf dem Maschinenrahmen abstützt, ist bei einer ununterbrochen sicheren Auflage während der kontinuierlichen Arbeitsvorfahrt jederzeit eine wahlweise Veränderung der Gleishöhe in bezug auf die Bettungsoberfläche möglich. Außerdem wird mit der Aufhängung am Maschinenrahmen auch eine störende Einflußnahme auf die unter der Gleishebevorrichtung befindliche Bettungsoberfläche vermieden. Durch die gelenkige Ausbildung wird insbesondere in Zusammenhang mit einem Schwenkantrieb eine Stabilisierung der Gleishebevorrichtung sowie eine seitliche Auslenkung der Baueinheit in bezug auf den Maschinenrahmen ermöglicht, um dem Gleisverlauf auch beim Durcharbeiten eines Gleisbogens problemlos folgen zu können. With such a track lifting device, the track lifting forces are from the drives transferable to the underside of the sleepers, without making contact with the rails needed. Hence the safety of the track support too in the case of rail butt joints changing the rail cross-section or the like. In no way impaired. Since the track lifting device over the Drives supported only on the machine frame is one at a time secure circulation at all times during the continuous right of way an optional change of the track height in relation to the bed surface possible. In addition, the suspension on the machine frame also becomes a nuisance Influencing the bedding surface under the track lifting device avoided. The articulated training is particularly related stabilization of the track lifting device with a swivel drive as well as a lateral deflection of the structural unit in relation to the machine frame allows to track the track even when working through a curve easy to follow.
Mit dem Merkmal gemäß Anspruch 2 ist die erfindungsgemäße Gleishebevorrichtung relativ rasch und einfach in bzw. außer Einsatzstellung zu bringen, ohne daß hierfür ein Durchtrennen eines Schienenstranges notwendig wäre. With the feature according to claim 2, the track lifting device according to the invention relatively quick and easy to bring in or out of use, without cutting a rail track would be necessary for this.
Die Variante gemäß den Ansprüchen 3 und 4 bietet den Vorteil einer sicheren Abstützung des Gleisrostes ungeachtet etwaiger Unregelmäßigkeiten der Schwellenunterseiten, wobei mit dem Merkmal nach Anspruch 5 die erforderliche Gleisanhebung zur Vermeidung einer unzulässigen Biegebelastung der Schienen möglichst gering gehalten werden kann. The variant according to claims 3 and 4 offers the advantage of secure support of the track grate regardless of any irregularities on the underside of the sleepers, with the feature of claim 5, the required track lifting to avoid an impermissible bending load on the rails if possible can be kept low.
Die in Anspruch 6 angeführte Weiterbildung ermöglicht es, das Rollelement bzw. die Raupenkette um eine horizontale Achse verschwenkbar auszubilden, um sich so besser an die gegebenenfalls ungleichmäßig verlaufenden Schwellenunterseiten anzupassen. The further development mentioned in claim 6 enables the rolling element or the To make the track chain pivotable about a horizontal axis, so as to better on the possibly unevenly running threshold undersides adapt.
Die Ausbildung nach Anspruch 7 ermöglicht eine noch flachere Ausbildung des Rollelementes bzw. der gesamten Gleishebevorrichtung unter Beibehaltung aller anderen Vorteile. The training according to claim 7 enables an even flatter training Roll element or the entire track lifting device while maintaining all other advantages.
Ist die Maschine gemäß Anspruch 8 ausgebildet, so kann das Gleis unter Erzielung einer langen Baulücke mit einer besonders sanften und materialschonenden Biegelinie angehoben werden. If the machine is designed according to claim 8, the track can be achieved a long vacant lot with a particularly gentle and gentle bending line be raised.
Schließlich ist mit der Variante gemäß Anspruch 9 auf konstruktiv einfache Weise das selbsttätige Nachführen der Vorrichtung im Gleisbogen gewährleistet, so daß die Rollelemente bezüglich der Schwellenlängsrichtung immer unverändert unter dem Gleis positioniert sind. Finally, the variant according to claim 9 is structurally simple ensures the automatic tracking of the device in the track arch, so that the rolling elements with respect to the longitudinal direction of the sleeper always unchanged are positioned on the track.
