Description

Die Erfindung betrifft eine Maschine zum Erneuern bzw. Verlegen eines Eisenbahngleises, mit einem endseitig auf Fahrwerken abgestützten nenrahmen, an dem eine Altschwellenaufnahmevorrichtung, eine Neuschwellenablagevorrichtung, eine zwischen diesen befindliche höhenverstellbare Schotterplaniereinrichtung sowie Führungseinrichtungen für Alt- bzw. Neuschienen vorgesehen sind, wobei an einem Ende des Maschinenrahmens sowohl ein Schienenfahrwerk als auch ein zum Maschinenrahmen höhenverstellbares, gleisungebundenes Fahrwerk angeordnet sind.The invention relates to a machine for renewing or laying a railroad track, with an end frame supported on running gears, on which an old sleeper pick-up device, a new sleeper storage device, a height-adjustable ballast leveling device located between them and guide devices for old or new rails are provided, at one end of the machine frame are arranged both a rail undercarriage and a track-independent undercarriage that is adjustable in height to the machine frame.

Aus der US 4,184,431 ist bereits eine derartige Maschine bekannt, die sowohl zum Verlegen eines neuen Eisenbahngleises als auch zum Erneuern eines alten Gleises eingesetzt werden kann. Die Maschine weist einen brückenförmigen, endseitig auf Schienenfahrwerken abgestützten Maschinenrahmen auf und ist an ihrem - bezüglich der Arbeitsrichtung, die für beide Einsatzvarianten gleich ist - hinteren Ende mit Schwellentransportwagen zu einem Zugsverband gekuppelt. Unmittelbar hinter dem vorderen Schienenfahrwerk ist ein gleisungebundenes Raupenfahrwerk höhenverstellbar mit dem Maschinenrahmen verbunden sowie in der abgesenkten Stellung lenkbar ausgebildet. Die Arbeitsaggregate für die Schwellenaufnahme und -ablage sind hinter dem Raupenfahrwerk an einem vertikal zum Maschinenrahmen verschwenkbaren Tragrahmen angeordnet, wobei die Altschwellenaufnahme- und die Schotterplaniervorrichtung zusätzlich zum Tragrahmen höhenverstellbar sind.Such a machine is already known from US Pat. No. 4,184,431, which can be used both for laying a new railroad track and for renewing an old track. The machine has a bridge-shaped machine frame supported at the end on rail running gear and is coupled at its rear end with respect to the working direction, which is the same for both types of use, with sleeper transport carriages to form a train set. Immediately behind the front rail undercarriage, a track-independent crawler undercarriage is connected to the machine frame in a height-adjustable manner and is steerable in the lowered position. The work units for the sleeper pick-up and storage are arranged behind the crawler track on a support frame that can be pivoted vertically to the machine frame, the height of the old sleeper pick-up device and the ballast leveling device being adjustable in addition to the support frame.

Beim Einsatz zum sogenannten Gleisumbau bzw. Erneuern eines Gleises fährt die bekannte Maschine - bei hochgehobenem Raupenfahrwerk - mit dem vorderen Schienenfahrwerk auf dem alten Gleis, während das hintere Schienenfahrwerk bereits auf dem neuen Gleis abrollt. Der Austausch der alten gegen die neuen Schwellen und Schienen sowie das Planieren der Schotterbettoberfläche erfolgt zwischen den Schienenfahrwerken bei kontinuierlicher Vorfahrt der Maschine, wobei ein Portalkran für den Zu- und Abtransport der Neu- und Altschwellen vorgesehen ist. Bei Verwendung der Maschine zum Verlegen eines neuen Gleises auf ein vorbereitetes Schotterbett wird das Raupenfahrwerk abgesenkt und dadurch das vordere Maschinenrahmenende mitsamt dem Schienenfahrwerk hochgehoben, sodaß die Maschine über das Raupenfahrwerk auf dem Schotter abrollt. Das hintere Schienenfahrwerk fährt wieder auf dem mittels der Arbeitsaggregate zwischen den Fahrwerken neu verlegten Gleis, wobei jedoch die Altschwellenaufnahmevorrichtung und die Schotterplaniervorrichtung in einer angehobenen Außerbetriebstellung verbleiben. Da die neuen bzw. auch die alten Schienen in dem relativ begrenzten Bereich zwischen der Neuschwellenablagevorrichtung und dem hinteren Schienenfahrwerk auf die endgültige Spurweite eingespreizt werden müssen, sind die Schienen ziemlich hohen, unter Umständen nicht mehr zulässigen Biegebelastungen ausgesetzt.When used for the so-called track conversion or renewal of a track, the known machine drives - with the crawler track raised - with the front track bogie on the old track, while the rear track bogie is already rolling on the new track. The replacement of the old sleepers and rails and the leveling of the ballast bed surface takes place between the rail carriages while the machine is moving forward continuously, whereby a gantry crane is provided for the transport in and out of the new and old sleepers. When using the Machine for laying a new track on a prepared ballast bed, the crawler track is lowered and thereby the front end of the machine frame together with the rail carriage is raised, so that the machine rolls over the crawler track on the ballast. The rear rail running gear again travels on the track newly laid between the running gears by means of the working units, but the old sleeper receiving device and the ballast leveling device remain in a raised non-operating position. Since the new or also the old rails have to be spread to the final track width in the relatively limited area between the new sleeper storage device and the rear rail running gear, the rails are exposed to rather high, possibly no longer permissible bending loads.

Eine weitere Maschine zum Erneuern und Verlegen von Gleisen ist in der US 4,207,820 beschrieben und weist einen zweiteiligen, gelenkig ausgebildeten Maschinenrahmen auf. Ein Rahmenteil ist auf zwei Schienenfahrwerken gelagert, während der andere Rahmenteil trailerartig daran angelenkt ist und an seinem freien Ende ein Fahrwerk und eine Fahrkabine besitzt. Im Bereich unterhalb der Gelenksverbindung ist ein an beiden Rahmenteilen gelenkig befestigter Tragrahmen für Schwellenaufnahme- und -ablagevorrichtungen sowie eine Schotterplaniervorrichtung vorgesehen. Beim Gleisumbau fährt die Maschine in jener Richtung, bei der sich die Fahrkabine am bezüglich der Arbeitsrichtung hinteren Ende befindet und das diesem zugeordnete Fahrwerk auf dem neuen Gleis abrollt, während das gegenüberliegende, vorderste Fahrwerk noch auf dem alten Gleis aufliegt. Das mittlere Fahrwerk im Bereich des Rahmengelenkes steht mit dem Gleis nicht in Eingriff; der Maschinenrahmen stützt sich hier über ein Hilfsfahrwerk auf den seitlich neben dem alten Gleis bereitliegenden Neuschienen ab. Im Falle einer Neugleisverlegung wird diese Maschine in der entgegengesetzten Richtung verfahren, d. h. mit der Fahrkabine in Arbeitsrichtung vorne, wobei dieses vordere Maschinenende über ein Hilfsfahrwerk auf den vorher bereitgelegten Neuschienenen abrollt. Eine hinter dem Hilfsfahrwerk angeordnete Vorrichtung verlegt die Neuschwellen, während die übrigen, im Bereich des Rahmengelenkes angeordneten Arbeitsaggregate nun außer Betrieb sind und die hinteren Fahrwerke auf dem neu verlegten Gleis fahren.Another machine for renewing and laying tracks is described in US 4,207,820 and has a two-part, articulated machine frame. One frame part is mounted on two rail bogies, while the other frame part is articulated to it like a trailer and has a bogie and a driving cabin at its free end. In the area below the articulated connection, a support frame, which is articulated on both frame parts, is provided for sleeper receiving and depositing devices, as well as a ballast leveling device. When converting the track, the machine travels in the direction in which the driver's cab is at the rear end with respect to the working direction and the running gear assigned to it rolls on the new track, while the opposite, front running gear still lies on the old track. The middle chassis in the area of the frame joint is not in engagement with the track; the machine frame is supported here by an auxiliary running gear on the new rails on the side next to the old track. In the event of a new track being laid, this machine is moved in the opposite direction, ie with the cab in the working direction at the front, this front machine end rolling over the previously prepared new rail via an auxiliary running gear. A device arranged behind the auxiliary running gear relocates the new sleepers, while the other working units arranged in the area of the frame joint are now out of operation and the rear running gear runs on the newly laid track.

Gemäß CH 680 865 A5 ist ein Verfahren bekannt, mittels dessen eine Maschine zum Erneuern eines Gleises bzw. ein sogenannter Gleisumbauzug in eine Maschine zum Verlegen eines Neugleises umgewandelt wird. Das während des Gleisumbaues in Arbeitsrichtung hinten gelegene, auf dem neuen Gleis abrollende Schienenfahrwerk ist zu diesem Zweck auf einem als Raupenfahrwerk ausgebildeten Fahrzeug mit eigenem Antrieb gelagert bzw. abgestützt, welches bei der Neugleisverlegung in der Baustelle auf dem Schotterbett verfährt und die Maschine nun in der entgegengesetzten Richtung antreibt. Zur Umrüstung der Maschine werden die diversen Arbeitsaggregate für den Schienen- bzw. Schwellenaustausch teilweise außer Betrieb genommen und teilweise zum Einsatz für die Gleisverlegung in der anderen Arbeitsrichtung adaptiert.According to CH 680 865 A5, a method is known by means of which a machine for renewing a track or a so-called track conversion train is converted into a machine for laying a new track. For this purpose, the rail undercarriage lying on the new track and rolling backwards while working on the track is supported or supported on a caterpillar undercarriage with its own drive, which moves on the ballast bed when the new track is laid in the construction site and the machine is now in the drives in the opposite direction. To retrofit the machine, the various work units for rail or sleeper replacement are partly taken out of operation and partly adapted for use in laying the track in the other direction.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Maschine der eingangs genannten Art, die bei einem Minimum an Umrüstarbeiten und vorteilhaftem Einsatz des gleisungebundenen Fahrwerkes für beide Einsatzmöglichkeiten, sowohl für die Neuverlegung eines Gleises als auch für den Gleisumbau, uneingeschränkt verwendbar ist.The object of the present invention is to create a machine of the type mentioned, which can be used without restriction with a minimum of retrofitting work and advantageous use of the track-independent running gear for both possible uses, both for relocating a track and for converting the track.

Diese Aufgabe wird dadurch gelöst, daß bei einer Maschine der gattungsgemäßen Art das gleisungebundene Fahrwerk durch eine erste Kupplung vom Maschinenrahmen lösbar ausgebildet und im Bereich des ebenfalls vom Maschinenrahmen lösbaren Schienenfahrwerkes eine zweite Kupplung zur Verbindung des gleisungebundenen Fahrwerkes mit dem Maschinenrahmen vorgesehen ist.This object is achieved in that, in the case of a machine of the generic type, the track-independent running gear is designed to be detachable from the machine frame by means of a first coupling, and a second coupling is provided in the region of the rail running gear, which is also detachable from the machine frame, for connecting the non-track running gear to the machine frame.

Mit einer derartigen Ausbildung ist die Maschine, bei der das gleisungebundene Fahrwerk sowohl bei der Neuverlegung als auch beim Gleisumbau einsetzbar ist, rasch und einfach sowohl für die Verlegung eines neuen Gleises als auch den Umbau eines alten Gleises verwendbar. Dazu ist lediglich die Entfernung des endseitig gelegenen Schienenfahrwerkes und die Versetzung des gleisungebundenen Fahrwerkes von der ersten zur zweiten Kupplung erforderlich. In vorteilhafter Weise kann in beiden Einsatzmöglichkeiten der lange Schienenbiegebereich sowie auch die Neuschwellenablagevorrichtung uneingeschränkt beibehalten bzw. eingesetzt werden.With such a design, the machine, in which the track-independent running gear can be used both when relocating and when remodeling the track, can be used quickly and easily both for laying a new track and for converting an old track. All that is required is the removal of the rail chassis located at the end and the displacement of the track-independent chassis from the first to the second coupling. Advantageously, the long rail bending area and also the new sleeper storage device can be maintained or used without restriction in both possible uses.

Die Weiterbildung nach Anspruch 2 ermöglicht es, bei Verfahren der Maschine für die beiden Einsatzvarianten in jeweils entgegengesetzter Arbeitsrichtung die Neuschwellen in vorteilhafter Weise immer unmittelbar hinter dem gleisungebundenen Fahrwerk abzulegen. Dadurch wird gewährleistet, daß auch bei relativ kurzer Ausbildung des Maschinenrahmens die Biegelinie der zu verlegenden Schienen besonders sanft verlaufen kann bzw. - insbesondere bei der Neuverlegung - ein maximaler Bereich unter dem Maschinenrahmen zum Einspreizen der Neuschienen zur Verfügung steht.The development according to claim 2 makes it possible, when moving the machine for the two application variants in opposite working directions, to always store the new sleepers directly behind the track-independent running gear. This ensures that even with a relatively short design of the machine frame, the bending line of the rails to be laid can run particularly gently or - especially when relocating - there is a maximum area under the machine frame for spreading out the new rails.

Die Ausbildung gemäß Anspruch 3 gestattet eine optimale Verfahrbarkeit der Maschine im Arbeitseinsatz, bei dem das Raupenfahrwerk problemlos und sicher auf jeglicher Bettungsoberfläche abrollbar ist.The design according to claim 3 allows the machine to be optimally moved during work, in which the crawler track can be rolled off easily and safely on any bedding surface.

In den Ansprüchen 4 und 5 wird eine bevorzugte Weiterbildung beschrieben, die bei konstruktiv einfacher und zuverlässiger Ausbildung eine rasche und mit einem Minimum an Arbeitsaufwand durchführbare Verlegung des gleisungebundenen Fahrwerkes von der ersten zur zweiten Kupplung und umgekehrt ermöglicht. Dabei erweist sich die Ausgestaltung gemäß Anspruch 6 von Vorteil, mittels derer die Stabilität der Abstützung des gleisungebundenen Fahrwerkes in Maschinenlängsrichtung wesentlich vergrößerbar ist.Claims 4 and 5 describe a preferred further development which, with a structurally simple and reliable design, enables the track-independent running gear to be moved quickly and with a minimum of work from the first to the second coupling and vice versa. The embodiment according to claim 6 proves to be advantageous, by means of which the stability of the support of the track-independent running gear in the machine longitudinal direction can be significantly increased.

Die Weiterbildungen nach den Ansprüchen 7 und 8 gewährleisten eine weitere Vereinfachung bzw. Optimierung der Umrüstarbeiten zur Versetzung des gleisungebundenen Fahrwerkes, die dadurch in besonders kurzer Zeit durchgeführt werden können.The further developments according to claims 7 and 8 ensure a further simplification or optimization of the retrofitting work for moving the track-independent running gear, which can thereby be carried out in a particularly short time.

Die Variante gemäß Anspruch 9 erweist sich insbesondere beim Einsatz der Maschine zum Gleisumbau als vorteilhaft und erhöht die Arbeitsleistung der Maschine, während die Ausbildung nach Anspruch 10 die Möglichkeit bietet, die Schwellenauflagerbereiche vor der Neuschwellenablage auf einfache Weise an Hand der Raupenketten zu verdichten.The variant according to claim 9 proves to be particularly advantageous when using the machine for track renewal and increases the work output of the machine, while the embodiment according to claim 10 offers the possibility of compacting the sleeper support areas before the new sleeper storage in a simple manner using the caterpillar tracks.

The machine has an elongated machine frame 3, which is provided with a rail carriage 4 at each of its two longitudinal ends. Another, track-free running gear 5 is arranged between them at the rear end of the machine frame 3 with respect to the working direction and is height-adjustable via drives 6. The machine frame 3 is further equipped with an old sleeper pick-up device 7, a ballast clearing device 8 following this in the working direction, height-adjustable ballast clearing device 9, and a new sleeper storage device 10, this between the rail chassis 4 attached to the rear end of the machine frame and the tracked crawler chassis adjacent to it in the machine longitudinal direction 11 trained track-free running gear 5 is provided. Guide devices 12, 13 for old rails 14 and new rails 15 are arranged on each long side of the machine frame 3, which is also provided with a the end cabin 16 and a work cabin 17 located approximately in the longitudinal center in the area of the old threshold receiving device 7.

In Fig. 2 ist ein über Schienenfahrwerke 18 auf den Altschienen 14 verfahrbarer Antriebswagen 19 dargestellt, auf dem das - der Fahrkabine 16 gegenüberliegende - Ende des Maschinenrahmens 3 der Maschine 1 im Arbeitseinsatz um eine vertikale Achse 20 verschwenk- und höhenverstellbar abgestützt ist. Der Antriebswagen 19 ist mit einer zentralen Kraftquelle 21 und einem Hydraulikaggregat 22 zur Energieversorgung aller Antriebe der Maschine 1 versehen und an seinem anderen, in Arbeitsrichtung vorderen Ende mit einem weiteren, trailerartigen Arbeitsfahrzeug 23 gekuppelt. Dieses weist eine höhenverstellbare Kleineisensammeleinrichtung 24 sowie zwei Wassertanks 25 auf, die mit am Antriebswagen 19 befindlichen Sprühdüsen 26 in Verbindung stehen. Das vordere Ende des Arbeitsfahrzeuges 23 ist mit einer Anzahl von (nicht dargestellten) Schwellentransportwagen 27 verbunden, wobei ein Portalkran 28 auf einer - sich durchgehend von den Transportwagen 27 bis zur Maschine 1 erstreckenden - Laufschiene 29 abrollt und lagenweise Altschwellen 30 bzw. Neuschwellen 31 von der bzw. zur Umbaustelle transportiert.2 shows a drive carriage 19 which can be moved on the old rails 14 via rail carriages 18 and on which the end of the machine frame 3 of the machine 1, which is opposite the driving cabin 16, is supported so as to be pivotable and adjustable in height about a vertical axis 20 during use. The drive car 19 is provided with a central power source 21 and a hydraulic unit 22 for supplying energy to all drives of the machine 1, and is coupled at its other front end in the working direction to another trailer-like work vehicle 23. This has a height-adjustable small iron collecting device 24 and two water tanks 25, which are connected to spray nozzles 26 located on the drive car 19. The front end of the work vehicle 23 is connected to a number of sleeper transport carriages 27 (not shown), a gantry crane 28 rolling on a running rail 29 extending continuously from the transport carriages 27 to the machine 1 and layered old sleepers 30 or new sleepers 31 from who transported to the conversion site.

Das gleisungebundene Fahrwerk 5 ist mit dem Maschinenrahmen 3 durch eine erste Kupplung 32 lösbar verbunden, und auch das unter der Fahrkabine 16 gelegene, endseitige Schienenfahrwerk 4 ist vom Maschinenrahmen 3 lösbar ausgebildet. Im Bereich dieses letztgenannten Schienenfahrwerkes 4 ist eine zweite Kupplung 33 vorgesehen, mittels der das gleisungebundene Fahrwerk 5 an der Stelle des - vorher demontierten - Schienenfahrwerkes 4 mit dem Maschinenrahmen 3 verbunden werden kann. Dieser Austausch der Fahrwerke 4 und 5 erfolgt unter Zuhilfenahme eines über einen Antrieb 48 höhenverstellbar mit dem Maschinenrahmen 3 verbundenen Hilfsfahrwerkes 34, das dem gleisungebundenen Fahrwerk 5 zugeordnet ist und auf dem sich die Maschine 1 während der Umsetzung der Fahrwerke abstützt.The track-independent undercarriage 5 is detachably connected to the machine frame 3 by a first coupling 32, and the end-side rail undercarriage 4 located under the driving cabin 16 is also detachable from the machine frame 3. In the area of this last-mentioned rail undercarriage 4, a second coupling 33 is provided, by means of which the track-independent undercarriage 5 can be connected to the machine frame 3 at the location of the - previously disassembled - rail undercarriage 4. This exchange of the trolleys 4 and 5 takes place with the aid of an auxiliary trolley 34 which is height-adjustable to the machine frame 3 via a drive 48 and which is assigned to the track-independent trolley 5 and on which the machine 1 is supported during the implementation of the trolleys.

In Fig. 3 ist die Maschine 1 nach der Entfernung des endseitigen Schienenfahrwerks 4 und Umsetzung des gleisungebundenen Fahrwerkes 5 von der ersten Kupplung 32 zur zweiten Kupplung 33 zu sehen. Auf diese Art umgerüstet, wird die Maschine zum Neuverlegen eines Gleises eingesetzt. Dieser Arbeitseinsatz erfolgt in der durch einen Pfeil 35 angegebenen Arbeitsrichtung, die im Vergleich zum Gleisumbau entgegengesetzt verläuft.In Fig. 3, the machine 1 can be seen after the removal of the rail carriage 4 at the end and implementation of the track-independent carriage 5 from the first coupling 32 to the second coupling 33. Converted in this way, the machine is used to relocate a track. This work is carried out in the direction of work indicated by an arrow 35, which is opposite to that of the track renewal.

Der Aufbau der zweiten Kupplung 33 ist in den Fig. 4 und 5 im Detail gezeigt. Das das gleisungebundene Fahrwerk 5 bildende Raupenfahrwerk 11 ist aus zwei in Maschinenquerrichtung voneinander distanzierten, parallel zueinander verlaufenden Raupenketten 36 gebildet. Das Raupenfahrwerk 11 weist eine mittig zwischen diesen Raupenketten 36 angeordnete Konsole 37 auf, deren Oberseite durch eine horizontale Platte 38 mit einem in deren Mitte befestigten Zentrierzapfen 39 gebildet ist. Ein Lager-Zwischenstück 40 in Form einer vertikalen Säule 41 ist mit seinem oberen Ende in einer Buchse 53 durch eine Flanschverbindung 54 lösbar mit dem Maschinenrahmen 3 verbunden und weist an seinem unteren Ende eine Öffnung 43 zur Aufnahme bzw. Einführung des Zentrierzapfens 39 sowie eine weitere Flanschverbindung 57 zur lösbaren Verbindung mit dem Lager-Zwischenstück 40 auf. Zur Stabilisierung der Abstützung des Raupenfahrwerkes 11 am Maschinenrahmen 3 in Maschinenlängsrichtung sind zwei Sicherungsstützen 44 vorgesehen, die einerseits an der Konsole 37 und andererseits am Maschinenrahmen 3 angelenkt sind und in einem etwa 45gradigen Winkel zur Gleisebene verlaufen. Die beiden Raupenketten 36 sind voneinander in einem Abstand von etwa 900 mm distanziert und mit einem Fahrantrieb 45 ausgestattet, der in beiden Drehrichtungen beaufschlagbar ist. Weiters ist im Bereich der zweiten Kupplung 33 eine Hydraulikkupplung 46 zum Anschließen der Hydraulikleitungen 47 des gleisungebundenen Fahrwerkes 5 vorgesehen, wobei eine entsprechende Hydraulikkupplung 42 auch im Bereich der ersten Kupplung 32 angeordnet ist.The structure of the second clutch 33 is shown in detail in FIGS. 4 and 5. The crawler undercarriage 11 forming the track-independent undercarriage 5 is formed from two caterpillar tracks 36 spaced apart from one another in the cross-machine direction and running parallel to one another. The crawler track 11 has a bracket 37 arranged centrally between these caterpillar tracks 36, the upper side of which is formed by a horizontal plate 38 with a centering pin 39 fastened in the middle thereof. A bearing intermediate piece 40 in the form of a vertical column 41 is detachably connected to the machine frame 3 at its upper end in a bushing 53 by a flange connection 54 and has an opening 43 at its lower end for receiving or introducing the centering pin 39 and another Flange connection 57 for detachable connection to the bearing intermediate piece 40. To stabilize the support of the crawler track 11 on the machine frame 3 in the machine longitudinal direction, two securing supports 44 are provided, which are articulated on the one hand on the bracket 37 and on the other hand on the machine frame 3 and run at an approximately 45 degree angle to the track plane. The two crawler tracks 36 are spaced apart from one another by about 900 mm and equipped with a travel drive 45 which can be acted upon in both directions of rotation. Furthermore, a hydraulic coupling 46 is provided in the region of the second coupling 33 for connecting the hydraulic lines 47 of the track-independent running gear 5, a corresponding hydraulic coupling 42 also being arranged in the region of the first coupling 32.

Im Arbeitseinsatz wird die Maschine 1 über die beiden Schienenfahrwerke 4 zur Gleisbaustelle verfahren, worauf das am der Fahrkabine 16 gegenüberliegenden Ende des Maschinenrahmens 3 angeordnete Schienenfahrwerk 4 - unter Abstützung des Maschinenrahmenendes auf dem Antriebswagen 19 - vom Gleis abgehoben und auf diese Art der Arbeitsbereich unterhalb des Maschinenrahmens 3 verlängert wird. Für den Einsatz zum Gleisumbau bzw. zur Gleiserneuerung (Fig. 1 und 2) stützt sich das hintere Ende des Maschinenrahmens 3 auf dem an Hand der Antriebe 6 auf die Schotterbettung in der Umbaulücke abgesenkten gleisungebundenen Fahrwerk 5 ab, während das benachbarte Schienenfahrwerk 4 dadurch mitsamt dem Maschinenrahmenende hochgedrückt wird und nicht im Einsatz ist. Bei kontinuierlicher Vorfahrt der Maschine 1 in Richtung des Pfeiles 2 werden nun die Schienenbefestigungsmittel entfernt und an Hand der Kleineisensammeleinrichtung 24 aufgenommen. Bei schwierigen Verhältnissen kommen auch die Sprühdüsen 26 zur Staubbekämpfung zur Anwendung. Die Altschienen 14 werden mittels der Führungseinrichtungen 12 von den Altschwellen 30 gehoben und jeweils zur Seite hin ausgespreizt, wonach die Altschwellen 30 mit der Altschwellenaufnahmevorrichtung 7 entfernt und nach vorne abtransportiert werden. An Hand der Schotterräumvorrichtung 8 und eines dieser zugeordneten, in Maschinenquerrichtung verlaufenden Abwurfförderbandes 49 sowie der in Arbeitsrichtung nachfolgenden Schotterplaniereinrichtung 9 wird die Oberfläche der Schotterbettung planiert und auf das gewünschte Querschnittsprofil gebracht, auf welchem das nachfolgende Raupenfahrwerk 11 abrollt. Unmittelbar hinter diesem werden mit der Neuschwellenablagevorrichtung 10 die vom Portalkran 28 herangebrachten Neuschwellen 31 verlegt. Die am Maschinenrahmenende angeordnete Führungseinrichtung 13 dient zum Einspreizen der Neuschienen 15, die sich nun zwanglos selbsttätig und mit - durch einen sehr langen Biegebereich - optimal sanfter Biegung hinter der Maschine 1 auf die Neuschwellen 31 einfädeln.In work, the machine 1 is moved over the two rail bogies 4 to the track construction site, whereupon the rail bogie 4 arranged at the end of the machine frame 3 opposite the driving cabin 16 - with the support of the machine frame end on the drive carriage 19 - is lifted off the track and in this way the working area below the Machine frame 3 is extended. For use in track conversion or track renewal (FIGS. 1 and 2), the rear end of the machine frame 3 is supported on the ballast bed in by the drives 6 the conversion gap lowered track-free undercarriage 5, while the adjacent rail undercarriage 4 is thereby pushed up together with the end of the machine frame and is not in use. With continuous advancement of the machine 1 in the direction of arrow 2, the rail fastening means are now removed and picked up using the small iron collecting device 24. In difficult conditions, the spray nozzles 26 are also used to combat dust. The old rails 14 are lifted from the old sleepers 30 by means of the guide devices 12 and each is spread out to the side, after which the old sleepers 30 are removed with the old sleepers receiving device 7 and transported away to the front. The surface of the ballast bedding is leveled and brought to the desired cross-sectional profile on which the subsequent crawler track 11 rolls using the ballast clearing device 8 and an associated discharge conveyor belt 49 running in the cross-machine direction and the ballast leveling device 9 following in the working direction. Immediately behind this, the new sleepers 31 are used to move the new sleepers 31 brought up by the portal crane 28. The guide device 13 arranged at the end of the machine frame serves to spread out the new rails 15, which are now automatically and automatically - with a very long bending area - optimally gentle bending behind the machine 1 onto the new sleepers 31.

Die Umrüstung des Raupenfahrwerkes 11 für den Einsatz der Maschine 1 zum Neuverlegen eines Gleises wird zweckmäßigerweise auf einer der Gleisbaustelle nächstgelegenen Weiche bzw. in einem angrenzenden Bahnhofsbereich durchgeführt. Vorerst erfolgt ein Absenken des Hilfsfahrwerkes 34 auf das Gleis. Anschließend werden die Antriebe 6 des Raupenfahrwerkes 11 von der Konsole 37 und ebenso die Hydraulikleitungen 47 von einer Hydraulikkupplung 56 gelöst. Durch ein weiteres Absenken des Hilfsfahrwerkes 34 erfolgt schließlich ein Anheben des Maschinenrahmens 3 und damit ein Loslösen vom endseitigen Schienenfahrwerk 4 und dem Raupenfahrwerk 11. Als nächstes wird die gesamte Maschine 1 durch einen Fahrantrieb 55 in der durch den Pfeil 2 dargestellten Richtung verfahren, bis die Konsole 37 des Raupenfahrwerkes 11 unterhalb der Buchse 53 zu liegen kommt. Daraufhin erfolgt mit Hilfe der Flanschverbindung 54 eine Fixierung des Lager-Zwischenstückes 40 am Maschinenrahmen 3. Mit Hilfe der zweiten Flanschverbindung 57 wird schließlich eine Verbindung des Lager-Zwischenstückes 40 mit dem Raupenfahrwerk 11 hergestellt. Dabei kann zweckmäßigerweise durch eine geringfügige Höhenverstellung des Hilfsfahrwerkes 34 die Einführung des Zentrierzapfens 39 erleichtert werden. Nach Fixierung der beiden Sicherungsstützen 44 und dem Anschluß der Hydraulikleitungen 47 an die zweite Hydraulikkupplung 46 ist die Neupositionierung und Fixierung des Raupenfahrwerkes 11 zur Neuverlegung eines Gleises abgeschlossen. Abschließend ist nur mehr eine Umkehrung der Schwellengabel 52 auf der Neuschwellenablagevorrichtung 10 erforderlich.The conversion of the crawler track 11 for the use of the machine 1 to relocate a track is expediently carried out on a switch nearest the track construction site or in an adjacent station area. For the time being, the auxiliary undercarriage 34 is lowered onto the track. Then the drives 6 of the crawler chassis 11 are released from the bracket 37 and likewise the hydraulic lines 47 from a hydraulic clutch 56. A further lowering of the auxiliary undercarriage 34 finally raises the machine frame 3 and thus releases it from the end-side rail undercarriage 4 and the crawler undercarriage 11. Next, the entire machine 1 is moved by a travel drive 55 in the direction shown by the arrow 2 until the Console 37 of the crawler chassis 11 comes to lie below the socket 53. The bearing intermediate piece 40 is then fixed on the machine frame 3 with the aid of the flange connection 54. With the aid of the second flange connection 57 is finally a connection of the bearing intermediate piece 40 to the crawler track 11. The insertion of the centering pin 39 can be expediently facilitated by a slight height adjustment of the auxiliary undercarriage 34. After the two securing supports 44 have been fixed and the hydraulic lines 47 have been connected to the second hydraulic coupling 46, the repositioning and fixing of the crawler tracks 11 for relocating a track is completed. Finally, only a reversal of the threshold fork 52 on the new threshold storage device 10 is required.

Die Maschine 1 wird anschließend unter Abstützung auf dem Hilfsfahrwerk 34 und bei angehobenem Raupenfahrwerk 11 aus dem Abzweiggleis, auf dem sich nunmehr das gelöste Schienenfahrwerk 4 befindet, zurück- und anschließend auf dem Stammgleis zur Baustelle verfahren (Pfeil 35). Sobald sich das Raupenfahrwerk 11 über der gleislosen Baustelle befindet, wird das Hilfsfahrwerk 34 in eine Außerbetriebstellung angehoben, wodurch parallel dazu das Raupenfahrwerk 11 auf die Schotterbettung abgesenkt wird. Während des Arbeitseinsatzes befinden sich die Schotterräumvorrichtung 8 und die Schotterplaniereinrichtung 9 ebenfalls in einer Außerbetriebstellung. Unter kontinuierlicher Vorfahrt der Maschine 1 in der durch den Pfeil 35 dargestellten Arbeitsrichtung erfolgt eine kontinuierliche Ablage der Neuschwellen 31 mit Hilfe der Neuschwellenablagevorrichtung 10. Die auf der Baustelle vorgelagerten Neuschienen 15 werden an Hand der Führungseinrichtungen 13 unmittelbar nach dem Schwellenablagebereich auf die Schwellen eingespreizt und abgelegt. Das Schienenfahrwerk 18 des Antriebwagens 19 ist bereits auf dem neuverlegten Gleis abrollbar.The machine 1 is then backed up on the auxiliary undercarriage 34 and with the crawler undercarriage 11 raised from the branch track on which the detached track undercarriage 4 is now located, and then moved to the construction site on the main track (arrow 35). As soon as the crawler track 11 is above the trackless construction site, the auxiliary undercarriage 34 is raised to a non-operating position, whereby the crawler track 11 is lowered in parallel to the ballast bed. During work, the ballast clearing device 8 and the ballast leveling device 9 are also in a non-operating position. The machine 1 is continuously moved forward in the working direction shown by the arrow 35 with the new sleepers 31 using the new sleepers storage device 10. The new rails 15 upstream on the construction site are spread and deposited on the sleepers using the guide devices 13 immediately after the sleepers storage area . The rail carriage 18 of the drive car 19 can already be rolled off on the newly laid track.
