Description

Die Erfindung betrifft eine Gleisbaumaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to a track construction machine according to the preamble of claim 1.

Eine derartige Maschine ist z.B. bereits aus US 4,342,165 oder US 4,774,890 bekannt und weist ein zur Überbrückung der Umbaulücke ausgebildetes Arbeitsfahrzeug auf. Der Maschinenrahmen des Fahrzeugs setzt sich aus zwei Rahmenteilen zusammen, die durch ein Rahmengelenk allseits verstellbar miteinander verbunden sind. Anhand eines Verstellantriebes ist die Distanz der beiden Rahmenteile in ihrem oberen Bereich zueinander veränderbar, wodurch ein darunter befindliches Schienenfahrwerk zwecks Vergrößerung der Umbaulücke von den Schienen abhebbar ist. An den Rahmenteilen sind Arbeitsaggregate zum Austauschen der Schienen bzw. Schwellen im Bereich der Umbaulücke vorgesehen.Such a machine is already off, for example US 4,342,165 or US 4,774,890 known and has a trained for bridging the Umbaulücke work vehicle. The machine frame of the vehicle is composed of two frame parts, which are connected to each other by a frame joint adjustable. Based on an adjustment, the distance between the two frame parts in its upper region is mutually variable, whereby an underlying Schienenfahrwerk for the purpose of enlarging the Umbaulücke of the rails can be lifted. On the frame parts working units are provided for exchanging the rails or sleepers in the area of the Umbaulücke.

Es ist weiters - beispielsweise aus US 3,699,894 oder US 3,685,456 - bekannt, zwei Rahmenteile eines Maschinenrahmens anhand eines dritten, zwischen diesen angeordneten Rahmenteiles gelenkig zu verbinden. Der mittige Rahmenteil ist wahlweise auf Schienenfahrwerken oder - im Bereich einer gleislosen Umbaulücke - auf schienenungebundenen Raupenfahrwerken auf der Gleisbettung abstützbar.It is further - for example US 3,699,894 or US 3,685,456 - Known to connect two frame parts of a machine frame based on a third, arranged between these frame part articulated. The central frame part can either be supported on rail chassis or - in the area of a trackless rear part - on track-bound crawler tracks on the track bed.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Gleisbaumaschine der eingangs genannten Art, mit der auch beim Arbeitseinsatz in Gleisbögen mit relativ engem Radius eine sichere Führung des Maschinenrahmens gewährleistet ist.The object of the present invention is now to provide a track construction machine of the type mentioned, with the safe operation of the machine frame is guaranteed even when working in track arcs with relatively narrow radius.

Diese Aufgabe wird erfindungsgemäß mit einer Maschine der gattungsgemäßen Art durch die im Kennzeichen von Anspruch 1 angeführten Merkmale gelöst.This object is achieved with a machine of the generic type by the features cited in the characterizing part of claim 1.

Eine derart ausgebildete Gleisbaumaschine bietet die vorteilhafte Möglichkeit, die Stabilität des Maschinenrahmens in Gleisquerrichtung bei Bedarf deutlich zu erhöhen, indem der im Arbeitseinsatz hochgespreizte, gelenkige Bereich der Maschine unter Absenkung des Raupenfahrwerkes auf der gleislosen Schotterbettung abgestützt wird. Gleichzeitig ist mit der erfindungsgemäßen Ausbildung aber alternativ auch der herkömmliche Betrieb weiterhin uneingeschränkt möglich, bei dem der hoch gespreizte Rahmen den Arbeitsbereich in der Umbaulücke frei überbrückt und ein Maximum an Freiraum für den Arbeitseinsatz bietet.Such a trained track construction machine offers the advantageous possibility to significantly increase the stability of the machine frame in the transverse direction of the track by the highly spread in the work, articulated area of the machine is supported by lowering the crawler undercarriage on the trackless ballast bedding. At the same time, however, with the embodiment according to the invention, alternatively, the conventional operation continues to be possible without restriction, in which the highly spread frame bridges the working area in the conversion gap freely and offers a maximum of free space for the labor input.

Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen und der Zeichnungsbeschreibung.Further advantages of the invention will become apparent from the dependent claims and the drawing description.

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

Fig. 1 eine Seitenansicht einer erfindungsgemäß ausgebildeten Maschine zur Gleiserneuerung, und Fig. 1 a side view of an inventively designed machine for track renewal, and

Fig. 2 eine schematische Draufsicht auf die Maschine beim Arbeitseinsatz in einem Gleisbogen. Fig. 2 a schematic plan view of the machine when working in a track curve.

Eine in den Fig. 1 und 2 dargestellte Gleisbaumaschine 1 dient zum kontinuierlichen Erneuern eines aus Schienen und Schwellen bestehenden Gleises 2 in einer durch einen Pfeil 3 angedeuteten Arbeitsrichtung. In bekannter Weise stützt sich dabei der bzgl. der genannten Arbeitsrichtung 3 vordere Abschnitt der Maschine 1 auf mit alten Schwellen 4 verbundenen alten Schienen 5 ab, während der hintere Maschinenabschnitt bereits auf - auf neuen Schwellen 6 verlegten - neuen Schienen 7 abrollt.One in the Fig. 1 and 2 Track construction machine 1 shown is used for continuous renewal of a track consisting of rails and sleepers 2 in a direction indicated by an arrow 3 working direction. In a known manner, the front section of the machine 1 is supported with respect to the aforementioned working direction 3 on old rails 5 connected to old sleepers 4, while the rear machine section already rolls on new rails 7 - laid on new sleepers 6.

Die Maschine 1 weist einen Maschinenrahmen 8 auf, der sich im Wesentlichen aus einem ersten bzw. in Arbeitsrichtung 3 vorderen Rahmenteil 9, einem zweiten, in Arbeitsrichtung nachfolgenden Rahmenteil 10 sowie einem zwischen diesen beiden angeordneten, dritten Rahmenteil bzw. Zwischenrahmen 11 zusammensetzt. Die beiden Rahmenteile 9 und 10 sind mit dem Zwischenrahmen 11 jeweils anhand eines (im Folgenden noch näher beschriebenen) Rahmengelenkes 12 allseits gelenkig verbunden.The machine 1 has a machine frame 8, which essentially consists of a first or in the working direction 3 front frame part 9, a second, following in the direction of frame part 10 and a disposed between these two, third frame part or intermediate frame 11. The two frame parts 9 and 10 are connected to the intermediate frame 11 in each case hingedly connected to each other on the basis of a frame joint 12 (described in more detail below).

Am vorderen Rahmenteil 9 befindet sich eine Vorrichtung (nicht gezeigt) zum Ausspreizen der alten Schienen 5, eine Vorrichtung 22 zur Aufnahme der alten Schwellen 4 sowie eine Planiereinrichtung 23 für eine Gleisbettung 21. Am hinteren Rahmenteil 10 sind eine Vorrichtung 24 zur Ablage der neuen Schwellen 6 sowie eine Einrichtung zum Einspreizen der neuen Schienen 7 vorgesehen.At the front frame part 9 is a device (not shown) for spreading out the old rails 5, a device 22 for receiving the old sleepers 4 and a leveling device 23 for a Track bed 21. At the rear frame part 10, a device 24 for storing the new sleepers 6 and a means for spreading the new rails 7 are provided.

Der erste und zweite Rahmenteil 9 und 10 sind an ihren freien Enden jeweils über ein erstes Schienenfahrwerk 13 auf dem Gleis 2 gelagert. Der Zwischenrahmen 11 ist mit zwei zweiten, mittleren Schienenfahrwerken 14 ausgestattet, die jeweils im Bereich eines Rahmengelenkes 12 angeordnet sind. Zusätzlich weist der Zwischenrahmen 11 ein zwischen den zweiten Schienenfahrwerken 14 positioniertes und anhand eines Antriebs 15 relativ zu diesen höhenverstellbares, schienenungebundenes Raupenfahrwerk 16 auf.The first and second frame part 9 and 10 are mounted at their free ends in each case via a first rail carriage 13 on the track 2. The intermediate frame 11 is equipped with two second, middle rail carriages 14, which are each arranged in the region of a frame joint 12. In addition, the intermediate frame 11 a positioned between the second rail bogies 14 and based on a drive 15 relative to these height-adjustable, rail-mounted crawler 16 on.

Jedes als Universalgelenk ausgebildete Rahmengelenk 12 verbindet den ersten bzw. zweiten Rahmenteil 9,10 mit dem Zwischenrahmen 11 im jeweils unteren Bereich der Rahmen. Im vertikal davon distanzierten, oberen Bereich sind die Rahmenteile 9, 10 mit dem Zwischenrahmen 11 jeweils über einen Verstellantrieb 17 verbunden, der als Spindelantrieb 18 ausgebildet ist. Durch diesen ist eine in dessen Längsrichtung verlaufende Distanz zwischen den beiden Rahmenteilen 9,10 veränderbar. Dieses Auseinanderspreizen bewirkt ein Anheben des jeweiligen Gelenkbereiches vom Gleis 2 in vertikaler Richtung. Bei gleichzeitiger Beaufschlagung der beiden Verstellantriebe 17 kommt es zu einer Anhebung des gesamten Zwischenrahmens 11 mitsamt seinen Fahrwerken 14 und 16, so dass der Maschinenrahmen 8 der Maschine 1 nunmehr ausschließlich auf den beiden endseitigen Schienenfahrwerken 13 abgestützt ist.Each formed as a universal joint frame joint 12 connects the first and second frame part 9,10 with the intermediate frame 11 in the respective lower region of the frame. In the vertically spaced-apart, upper area, the frame parts 9, 10 are connected to the intermediate frame 11 in each case via an adjusting drive 17, which is designed as a spindle drive 18. By this extending in the longitudinal direction of the distance between the two frame parts 9,10 is changeable. This spreading apart causes a lifting of the respective hinge portion of the track 2 in the vertical direction. With simultaneous loading of the two adjusting drives 17 there is an increase in the entire intermediate frame 11 together with its chassis 14 and 16, so that the machine frame 8 of the machine 1 is now supported exclusively on the two end rail carriages 13.

Um die seitliche Stabilität des Maschinenrahmens 8 im Bereich der Rahmengelenke 12 zu erhöhen, sind die Rahmenteile 9 und 10 mit dem Zwischenrahmen 11 zusätzlich jeweils über Lenkhebel 19 verbunden. Diese sind jeweils in Maschinenquerrichtung voneinander distanziert beidseitig des Rahmengelenkes 12 positioniert und als Hydraulikantriebe 20 ausgebildet, mittels derer die Rahmenteile 9 und 10 relativ zum Zwischenrahmen 11 in horizontaler Richtung ausgerichtet werden können, um - wie in Fig. 2 zu sehen - den lang gestreckten und nur endseitig über die ersten Schienenfahrwerke 13 abgestützten Maschinenrahmen 8 an die Krümmung eines Gleisbogens anpassen zu können.In order to increase the lateral stability of the machine frame 8 in the region of the frame joints 12, the frame parts 9 and 10 are additionally connected to the intermediate frame 11 in each case via steering levers 19. These are each spaced apart in the cross-machine direction on both sides of the frame joint 12 and formed as hydraulic drives 20, by means of which the frame parts 9 and 10 can be aligned relative to the intermediate frame 11 in the horizontal direction to - Fig. 2 to see - to be able to adapt the elongated machine frame 8, which is only supported at the ends by the first rail carriages 13, to the curvature of a curved track.

Wenn der Radius des genannten Gleisbogens besonders eng ist, besteht die Gefahr, dass der Schwerpunkt der Rahmenteile die durch die endseitigen ersten Schienenfahrwerke 13 bestimmte Kippkante erreicht. Um diese instabile Situation zuverlässig auszuschließen, wird das Raupenfahrwerk 16 mit Hilfe des Antriebs 15 abgesenkt und auf der Gleisbettung 21 hilfsweise abgestützt. Damit ist auch in engen Gleisbögen eine ausreichende Stabilität der Gleisbaumaschine 1 bzw. des Maschinenrahmens 8 sowie der daran angeordneten Arbeitsaggregate 22, 23 und 24 gewährleistet.If the radius of said track curve is particularly narrow, there is a risk that the center of gravity of the frame parts reaches the tilting edge determined by the end-side first rail bogies 13. To reliably exclude this unstable situation, the crawler undercarriage 16 is lowered by means of the drive 15 and supported on the track bed 21 in the alternative. This ensures sufficient stability of the track-laying machine 1 or of the machine frame 8 and of the working units 22, 23 and 24 arranged thereon even in narrow track curves.
