Description
Die Erfindung betrifft eine Gleisbaumaschine zum Aushub von Bettungsmaterial eines Gleises mit einem auf Schienenfahrwerken abgestützten, einen nach oben gekröpft ausgebildeten Abschnitt aufweisenden Maschinenrahmen, dem bezüglich der Arbeitsrichtung der Maschine eine Schotteraufnahmeeinrichtung mit einer Schotterabwurfstelle, eine durch Antriebe höhenverstellbare Aushubkette, eine Gleishebeeinrichtung, eine Arbeitskabine und eine Transporteinrichtung zum Abtransport des durch die Aushubkette aufgenommenen Bettungsmaterials in Maschinenlängsrichtung zugeordnet sind.The invention relates to a track construction machine for excavating bedding material of a track with supported on rail chassis, an upturned trained section machine frame, with respect to the working direction of the machine a ballast receiving device with a ballast discharge point, a height adjustable by drives excavation chain, a track lifting device, a work cabin and a transport device for removing the ballast material picked up by the excavating chain in the machine longitudinal direction are assigned.
Durch die gattungsgemäße EP 0 663 472 A1 ist eine Gleisbaumaschine zur Reinigung der Schotterbettung eines Gleises bekannt, wobei der um den Maschinenrahmen herumgeführten Aushubkette eine Siebanlage zugeordnet ist. Durch eine im hinteren Endbereich befindliche Schotteraufnahmeeinrichtung besteht die Möglichkeit, zusätzlich zum gereinigten Schotter in einem Speicherwagen vorrätig gehaltenen Schotter zur Herstellung der neuen Schotterbettung zuzuführen. Der Aushubkette ist ein mit einer Unterdruckanlage in Verbindung stehendes, höhen- und querverstellbares Saugrohr vorgeordnet. Mit diesem besteht die Möglichkeit, vor dem Einsatz der Aushubkette Schotter zur Bildung eines sogenannten Kofferloches abzusaugen. Diese Ausnehmung ist für das Einschieben eines Querkettenabschnittes der Aushubkette in die Schotterbettung unterhalb des Gleises erforderlich.The generic EP 0 663 472 A1 discloses a track-laying machine for cleaning the ballast bed of a track, wherein the excavating chain guided around the machine frame is assigned a screening system. By means of a ballast receiving device located in the rear end area, it is possible to supply ballast held in stock in a storage truck in addition to the cleaned ballast in order to produce the new ballast bed. The excavation chain is preceded by a suction pipe communicating with a vacuum system, adjustable in height and transversely. With this it is possible to suck before the use of Aushubkette gravel to form a so-called boot hole. This recess is required for the insertion of a cross-chain section of the excavation chain in the ballast bed below the track.
Eine weitere Gleisbaumaschine ist durch US 5 257 580 bekannt und dient zum Aushub von Bettungsmaterial in Verbindung mit der Herstellung einer Planumschutzschichte. Die für eine hohe Aushubleistung ensprechend groß dimensionierte Aushubkette ist in ihrem oberen Endbereich um den Maschinenrahmen herumgeführt, wodurch dieser in diesem Abschnitt einen reduzierten Querschnitt mit einem daraus resultierenden konstruktiv vergrößerten Aufwand aufweisen muß. Mit der im hinteren Endbereich positionierten Schotteraufnahmeeinrichtung ist eine kontinuierliche Zufuhr von neuem Schotter möglich, während der verunreinigte Schotter durch die Aushubkette und die Transporteinrichtung vorgeordneten Speicherwagen zugeführt wird.Another track laying machine is known from US 5 257 580 and is used for excavating bedding material in connection with the production of a Planumschutzschicht. For a high excavation capacity ensprechend large-dimensioned excavating chain is guided around in its upper end to the machine frame, whereby this must have a reduced cross-section with a resulting structurally increased effort in this section. With the ballast receiving device positioned in the rear end region, a continuous supply of new ballast is possible, while the contaminated ballast is fed through the excavating chain and the transport device upstream storage trolley.
Das in Arbeitsrichtung der Aushubkette vorgeordnete vierachsige Schienenfahrwerk ist in Maschinenlängsrichtung relativ zum Maschinenrahmen verschiebbar ausgebildet, so daß das Gleis für einen ungestörten Einsatz der entsprechend groß dimensionierten Aushubkette entsprechend hoch anhebbar ist.The upstream in the working direction of Aushubkette four-axis track gear is designed to be displaceable in the machine longitudinal direction relative to the machine frame, so that the track for undisturbed use of the correspondingly large-sized excavation chain is raised accordingly high.
Schließlich ist es auch noch durch US 4 502 389 und US 4 357 874 bereits bekannt, in Verbindung mit der abschnittsweisen Entfernung eines Gleisjoches eine Aushubkette zur Entfernung der Schotterbettung einzusetzen. Dazu muß allerdings der Maschinenrahmen unter entsprechend weiter Distanzierung der Schienenfahrwerke länger als einem Gleisjochabschnitt entsprechend ausgebildet werden.Finally, it is also known from US 4 502 389 and US 4 357 874, in conjunction with the partial removal of a track yoke to use a Aushubkette to remove the ballast bedding. For this purpose, however, the machine frame must be designed according to further distancing the rail bogies longer than a track yoke section.
Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Gleisbaumaschine der gattungsgemäßen Art, die sich besonders für einen raschen und effizienten Arbeitseinsatz in kürzeren Gleisabschnitten eignet.The object of the present invention is now to provide a track construction machine of the generic type, which is particularly suitable for a quick and efficient labor input in shorter track sections.
Diese Aufgabe wird erfindungsgemäß mit einer Gleisbaumaschine der eingangs beschriebenen Art dadurch gelöst, daß die Aushubkette mit ihrem im oberen Endbereich positionierten Kettenantrieb sowie ein Schotterräumaggregat mit einem durch Antriebe höhen- und senkrecht zur Maschinenlängsrichtung querverstellbaren Schotterräumorgan unterhalb des nach oben gekröpft ausgebildeten Abschnittes und die Gleishebeeinrichtung zwischen Aushubkette und Schotterräumaggregat angeordnet sind, und daß als Schotterabwurfstelle ausgebildete Schurren unmittelbar hinter einem unterhalb der Aushubkette befindlichen Aufnahmeende der Transporteinrichtung angeordnet sind.This object is achieved with a track construction machine of the type described above in that the excavation chain with her positioned in the upper end chain drive and a Schotterräumaggregat with a height-adjustable by drives and perpendicular to the machine longitudinal direction Schotterräumorgan below the upwardly cranked section and the track lifting between Excavating chain and Schotterräumaggregat are arranged, and that designed as a ballast chute chutes are located immediately behind a located below the Aushubkette receiving end of the transport device.
Eine mit diesen Merkmalen ausgestattete Maschine ist mit einem Minimum an konstruktivem Aufwand herstellbar und insbesondere in Verbindung mit dem Schotterräumaggregat auch in kurzen Gleissperrzeiten effizient einsetzbar. Ein reduzierter konstruktiver Aufwand ergibt sich besonders durch die vereinfachte Rahmenausbildung, bei der sich eine aufwendige Querschnittsreduktion zur Umschließung durch die Aushubkette erübrigt. Die aus der Anordnung der Aushubkette unterhalb des Maschinenrahmens resultierende verkürzte Kettenlänge ergibt auch einen kürzeren Transportweg zum Abwurf des Bettungsmaterials auf die Transporteinrichtung. Mit dem Schotterräumaggregat ist in besonders rascher und vereinfachter Weise ein querverlaufender Kanal unterhalb des Gleises zum Einfädeln der Aushubkette herstellbar. Außerdem ist durch die Anordnung der Aushubkette und des Schotterräumaggregates unterhalb des nach oben gekröpften Abschnittes des Maschinenrahmens eine besonders gute Sicht von der Arbeitskabine aus erreichbar.A equipped with these features machine can be produced with a minimum of design effort and efficient, especially in conjunction with the Schotterräumaggregat even in short track lock times. A reduced design effort is particularly due to the simplified frame design, in which a costly cross-sectional reduction is unnecessary for enclosure by the excavation chain. The resulting from the arrangement of the excavating chain below the machine frame shortened chain length also results in a shorter transport path for dropping the bedding material on the transport device. With the Schotterräumaggregat a transverse channel below the track for threading the excavation chain can be produced in a particularly rapid and simplified manner. In addition, by the arrangement of the excavation chain and the Schotterräumaggregates below the upwardly bent portion of the machine frame a particularly good view of the work from reachable.
