Description

Die Erfindung betrifft eine gleisverfahrbare Gleisbaumaschine, insbesondere Schotterbett-Reinigungsmaschine, mit einer um das Gleis herumgeführten Förder- bzw. Räumkette zum Aufnehmen des Schotters aus dem Bereich unterhalb des Gleises, einer mit dem aufgenommenen Schotter beschickbaren Siebanlage sowie mit einer Vorrichtung zum Wiedereinbringen des gereinigten Schotters durch Abwurf oberhalb des Gleises im Bereich hinter der Förder- bzw. Räumkette und einer unter dem, aus Schwellen und Schienen bestehenden Gleisgerippe hindurchführenden und sich quer zur Maschinenlängsrichtung erstreckenden, balkenförmigen Schotter-Verdichteinrichtung, die jeweils endseitig über mit einem Antrieb verbundene Trägerpfosten am Maschinenrahmen befestigt ist.The invention relates to a track-moving track construction machine, in particular ballast bed cleaning machine, with a conveyor or clearing chain guided around the track for picking up the ballast from the area below the track, a screening system which can be loaded with the picked up ballast, and with a device for reintroducing the cleaned ballast by dropping above the track in the area behind the conveyor or clearing chain and a beam-shaped ballast compacting device that runs under the track structure consisting of sleepers and rails and extends transversely to the machine's longitudinal direction, each of which is attached to the machine frame at the end via support posts connected to a drive is.

Es ist - gemäß AT-A-369 805 der gleichen Anmelderin - bereits eine derartige Schotterbett-Reinigungsmaschine mit einer Förder- bzw. Räumkette zum Aufnehmen des Schotters aus dem Bereich unterhalb des Gleises bekannt. Der Förder- bzw. Räumkette ist in Arbeitsrichtung eine Siebanlage zum Reinigen des aufgenommenen Schotters nachgeordnet. Unterhalb der Siebanlage ist eine als Abwurf-Förderband ausgebildete Vorrichtung zum verteilten Wiedereinbringen des gereinigten Schotters durch Abwurf auf das freigelegte Planum im Bereich unmittelbar hinter der Förder- bzw. Räumkette vorgesehen. Hinter der Abwurfstelle für den gereinigten Schotter ist weiters eine unterhalb des Gleisrostes durchgeführte Planier- und Verdichtvorrichtung über seitlich der Schwellen angeordnete, als Parallelogrammführungen ausgebildete Träger am Maschinenrahmen angelenkt und durch einen Verschwenkantrieb höhenverstellbar. Die in Arbeitsrichtung der Verdichtvorrichtung vorgeordnete Planiervorrichtung ist aus zwei endseitig jeweils an die Träger angelenkten und durch einen Antrieb um eine vertikale Achse verschwenkbaren Planierketten gebildet, die zur Rotation in Horizontalebene jeweils mit einem Drehantrieb verbunden sind. Die über in Maschinenlängsrichtung verlaufende Längsträger mit der Planiervorrichtung verbundene und dieser nachgeordnete Verdichtvorrichtung ist aus einem quer zur Maschinenlängsrichtung verlaufenden Balken gebildet, dessen äußere Enden mit einem der beiden Längsträger elastisch nachgiebig verbunden sind und der von einem Vibrationsantrieb in Schwingungen versetzbar ist. Mit dieser Planier- und Verdichtvorrichtung wird der vom Abwurf-Förderband durch das Gleis auf das Planum relativ unregelmäßig abgeworfene Schotter mit den rotierbaren Planierketten auf gleiche Höhe gebracht und anschließend durch die Verdichtvorrichtung von oben her komprimiert. Diese Vorrichtung ist relativ umfangreich, da zwei Einheiten - eine Planierund Verdichtvorrichtung - notwendig sind und erfordert daher oft eine höhere Anhebung des Gleises, da die beiden höhenverstellbaren Vorrichtungen zwischen dem oberen Schotterbett-Niveau und dem Gleisgerippe angeordnet sind. Die Verdichtwirkung ist jedoch nicht immer ausreichend, da oft Schotterlücken bedingt durch den unregelmäßig abgeworfenen Schotter vorhanden sind. Dies ist dort nachteilig, wo die Schwellen dann zur Auflage kommen.According to AT-A-369 805 by the same applicant, such a ballast bed cleaning machine with a conveyor or clearing chain for picking up the ballast from the area below the track is already known. The conveyor or clearing chain is followed by a screening system in the working direction for cleaning the ballast that has been picked up. Below the screening plant, a device designed as a discharge conveyor belt is provided for the distributed reintroduction of the cleaned ballast by discharge onto the exposed formation in the area immediately behind the conveyor or clearing chain. Behind the discharge point for the cleaned ballast, a leveling and compacting device carried out beneath the track grate is articulated on the machine frame via supports arranged as parallelogram guides and adjustable in height by means of a swivel drive. The leveling device arranged upstream in the working direction of the compacting device is formed from two leveling chains which are articulated on the ends at the ends and can be pivoted by a drive about a vertical axis and are each connected to a rotary drive for rotation in the horizontal plane. The longitudinal girder connected to the leveling device via the longitudinal girder extending in the longitudinal direction of the machine is formed by a bar running transversely to the longitudinal direction of the machine, the outer ends of which are elastically yieldingly connected to one of the two longitudinal girders and which can be set in motion by a vibration drive. With this leveling and compacting device, the ballast, which is thrown relatively irregularly from the discharge conveyor belt through the track onto the level, is brought to the same height with the rotating leveling chains and then compressed from above by the compacting device. This device is relatively extensive since two units - a leveling and compacting device - are necessary and therefore often requires a higher lifting of the track, since the two height-adjustable devices are arranged between the upper ballast bed level and the track frame. However, the compaction effect is not always sufficient, as there are often gravel gaps due to the irregularly dropped gravel. This is disadvantageous where the sleepers then come to rest.

Es ist auch - gemäß AT-A-329 107 der gleichen Anmelderin - eine Schotterbett-Reinigungsmaschine mit einer unter das Gleis hindurchgeführten Förder- bzw. Räumkette zum Aufnehmen des Schotters bekannt. Dieser Förder- bzw. Räumkette ist eine Siebanlage zum Reinigen des Schotters nachgeordnet. Als Vorrichtung zum verteilten Wiedereinbringen des gereinigten Schotters von der Siebanlage auf das freigelegte Planum ist ein oder sind auch zwei in horizontaler Ebene verschwenkbare Abwurf-Förderbänder vorgesehen. Der Förder- bzw. Räumkette ist weiters eine planiervorrichtung nachgeordnet, die aus einer sich über die gesamte Schwellenlänge erstreckenden, gelenkförmig ausgebildeten Balkenanordnung besteht. Diese setzt sich aus einem mittigen, parallel zur Schwellenlängsrichtung verlaufenden Querglied und zwei äußeren, mit diesem durch Gelenke verbundenen 4uergliedern zusammen. Die beiden äußeren Enden der äußeren Querglieder sowie die Gelenke sind durch Seile an der Förder- bzw. Räumkette frei beweglich befestigt. Mit einer solchen nachgezogenen Planiereinrichtung soll der durch das Abwurf-Förderband abgeworfene Schotter annähernd gleichmäßig verteilt werden, wobei aber doch durch die relativ grobe Verteilwirkung der Verteilbänder ebenso oft Schotterlücken entstehen.According to AT-A-329 107 by the same applicant, a ballast bed cleaning machine with a conveyor or clearing chain which is passed under the track for receiving the ballast is also known. This conveyor or clearing chain is followed by a screening system for cleaning the ballast. One or two discharge conveyor belts which can be pivoted in the horizontal plane are provided as a device for the distributed reintroduction of the cleaned ballast from the screening plant onto the exposed planum. The conveyor or clearing chain is further followed by a leveling device, which consists of an articulated bar arrangement extending over the entire threshold length. This consists of a central cross-member running parallel to the longitudinal direction of the sleeper and two outer cross-members connected to it by joints. The two outer ends of the outer cross links and the joints are fastened to the conveyor or clearing chain with cables so that they can move freely. With such a trailed leveling device, the ballast thrown off by the discharge conveyor belt should be distributed approximately uniformly, but ballast gaps also often occur due to the relatively rough distribution effect of the distribution belts.

Die Aufgabe der Erfindung besteht darin, daß bei Schotterbehandlungsmaschinen mit Reinigungsanlagen, wie Förder- und Räumkette mit Gleishebevorrichtung und Wiedereinbringen des gereinigten Schotters, der abgeworfene Schotter einer verbesserten Zuordnung unterworfen bzw. eine Anhäufung zu den richtigen Stellen erzielt wird, um dem Gleisgerippe eine bessere Auflage zu ermöglichen.The object of the invention is that in ballast treatment machines with cleaning systems, such as conveyor and clearing chain with track lifting device and reintroduction of the cleaned ballast, the thrown ballast is subjected to an improved assignment or an accumulation to the correct locations is achieved in order to provide the track structure with a better support to enable.

Die Aufgabe der Erfindung wird nun mit der eingangs beschriebenen gleisverfahrbaren Gleisbaumaschine dadurch erreicht, daß die als plattenförmiger Verdichtbalken ausgebildete Schotter-Verdichteinrichtung direkt im oder vor dem Bereich des auf das Planum abgeworfenen Schotters angeordnet ist, und daß der mit dem Trägerpfosten verbundene Antrieb für eine kontinuierlich etwa in Gleisebene hin- und hergehende Pendelbewegung - für eine Vorverdichtung des Schotters entgegen der Arbeitsrichtung - ausgebildet ist.The object of the invention is now achieved with the track-moving track construction machine described in the introduction in that the ballast compacting device designed as a plate-shaped compacting bar is arranged directly in or in front of the area of the ballast thrown onto the formation, and in that the drive connected to the support post for a continuous about back and forth pendulum movement in the track plane - for pre-compaction of the ballast against the working direction - is formed.

Eine derartige Verdichteinrichtung ermöglicht eine sofortige Verlagerung des zwischen den Schwellen auf das Planum abgeworfenen Schotters in einem kontinuierlichen Schoppvorgang auch unterhalb der Schwellen, wobei durch deren Widerstand eine Vorverdichtung des Schotters erzielbar ist. Damit liegt das Gleis bereits unmittelbar nach dem Schotterabwurf in einer gewünschten und kontrollierbaren Lage auf bereits vorverdichteten Schwellenauflager auf, so daß die durch das folgende Fahrwerk der Gleisbaumaschine ausgeübte Belastung auf das Gleis für eine weitere gleichmäßige Vorverdichtung der Schwellenauflager ausnützbar ist. Mit dem Einsatz eines plattenförmigen Verdichtbalkens kann dessen Schoppbewegung direkt im Schotterbett durchgeführt werden, wodurch in vorteilhafter Weise das Gleis im Bereich der Verdichteinrichtung nicht über das Soll-Niveau angehoben werden muß und daher die Schwellenunterseite als Widerstand für die Schoppbewegungen verwendbar ist.Such a compacting device enables an immediate displacement of the ballast dropped between the sleepers onto the formation in a continuous manner Schoppvorgang also below the thresholds, a pre-compression of the ballast can be achieved by their resistance. Thus, the track is already in a desired and controllable position on pre-compacted sleeper supports immediately after the ballast discharge, so that the load exerted on the track by the following running gear of the track construction machine can be exploited for a further uniform pre-compression of the sleeper supports. With the use of a plate-shaped compacting beam, its piling movement can be carried out directly in the ballast bed, which advantageously means that the track in the area of the compacting device does not have to be raised above the desired level and the underside of the sleeper can therefore be used as resistance to the piling movements.

Eine besonders bevorzugte Ausführungsform der Erfindung besteht darin, daß der für ein Zusammenschieben des abgeworfenen Schotters schoppartige Verdichtbalken aus zwei zur Maschinenlängs-Symmetrieebene spiegelbildlich ausgebildeten Halbteilen gebildet ist, die jeweils im Bereich des mit seinem oberen Ende am Maschinenrahmen befestigten Trägerpfostens um eine vertikale Achse nach außen zum Außereingriff außerhalb der Schwellen verschwenkbar gelagert und jeweils mit einem am Trägerpfosten befestigten Antrieb verbunden sind. Durch diese zweiteilige Ausbildung des Verdichtbalkens ist dessen problemlose und rasche In- bzw. Außerbetriebnahme durchführbar, indem die verschwenkbar am Trägerpfosten angelenkten Halbteile in eine seitlich des Gleises befindliche Ruheposition oder in eine unterhalb der Schwellen befindliche Arbeitsposition verschwenkt werden. Damit erübrigen sich zeitaufwendige Umrüstarbeiten.A particularly preferred embodiment of the invention consists in that the loop-like compacting bar for pushing together the thrown-up ballast is formed from two half-parts which are mirror images of the machine longitudinal plane of symmetry, each around a vertical axis in the area of the support post attached to the machine frame with its upper end are pivotally mounted for disengagement outside the sleepers and are each connected to a drive attached to the support post. This two-part design of the compacting bar means that it can be put into operation and taken out of operation quickly and easily by pivoting the pivotable half-parts on the support post into a rest position located to the side of the track or into a working position below the sleepers. This saves time-consuming retrofitting work.

Eine besonders vorteilhafte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß die beiden Halbteile durch eine lösbare Versteifungsplatte miteinander verbindbar sind. Durch die Verbindung der beiden Halbteile mit einer Versteifungsplatte wird die Festigkeit des durch beide Halbteile gebildeten Verdichtbalkens auf einfache Weise wesentlich erhöht. Dadurch kann die Vorverdichtwirkung für den. Schotter noch verbessert werden, außerdem wird den durch die kontinuierlich zyklische Schlagbewegung bedingten großen mechanischen Beanspruchungen besser standgehalten.A particularly advantageous embodiment of the invention is characterized in that the two half parts can be connected to one another by a releasable stiffening plate. By connecting the two half parts with a stiffening plate, the strength of the compression bar formed by both half parts is increased significantly in a simple manner. As a result, the pre-compression effect for the. Ballast can still be improved, and the large mechanical stresses caused by the continuously cyclical impact movement are better withstood.

Gemäß einer weiteren vorteilhaften Ausbildung der Erfindung ist vorgesehen, daß der als zweiteiliger Schopp-Balken ausgebildete Verdichtbalken an seinen äußeren Enden mit je einem am Maschinenrahmen angelenkten, als zweiseitiger Hebel ausgebildeten Trägerpfosten verbunden ist die mit ihrem oberen Teil jeweils mit einem als verschwenkbarer HydraulikZylinder-Kolben-Antrieb ausgebildeten Antrieb gelenkig verbunden sind, wobei vorzugsweise die beiden Trägerpfosten für den zweiteiligen Schopp-Balken durch Lösung der Versteifungsplatte unabhängig betätigbar bzw. nach außen außer Eingriff schwenkbar sind. Eine derartige einfache Ausbildung der Trägerpfosten als zweiteiliger Hebel eignet sich besonders für eine leistungsfähige Übertragung großer Verdichtkräfte vom Antrieb auf den Verdichtbalken. Mit der Verschwenkbarkeit der endseitig an den Trägerpfosten befestigten Halbteile des Verdichtbalkens ist ein rascher und problemloser Übergang von der Arbeits- in die Überstellposition durchführbar.According to a further advantageous embodiment of the invention, it is provided that the compression bar, which is designed as a two-part Schopp bar, is connected at its outer ends to a support post, which is articulated on the machine frame and is designed as a two-sided lever, the upper part of which is connected to a hydraulic cylinder piston which can be pivoted -Drive trained drive are articulated, preferably the two support posts for the two-part Schopp-beam can be operated independently by loosening the stiffening plate or pivoted out of engagement. Such a simple design of the support post as a two-part lever is particularly suitable for an efficient transmission of large compacting forces from the drive to the compacting bar. With the pivoting of the half-parts of the compacting bar, which are fastened at the end to the support post, a quick and easy transition from the working position into the transfer position can be carried out.

Eine bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß der Schopp-Balken im Querschnitt eine - von oben nach unten gesehen - konvexe Wölbung aufweist, deren unterste Kante in dem in Arbeitsrichtung vorderen Teil der Wölbung und deren oberste Kante in Verdichtrichtung bis unmittelbar nahe der Schwellenunterkante reicht, wobei jeweils am äußeren Ende eine Verstärkungsplatte zur Befestigung mit dem Balken selbst und mit dem über dem Maschinenrahmen verbundenen Trägerpfosten vorgesehen ist. Mit der gewölbten Ausbildung des Schopp-Balkens ist in Verdicht- bzw. Maschinenlängsrichtung ein großflächiger Angriff auf die abgeworfenen Schotteranhäufungen für deren rasche Verlagerung und Verdichtung in den Bereich unterhalb der Schwellen möglich. Außerdem wird durch die Wölbung ein sofortiges Abfließen des kontinuierlich vom Schotterauslaß der Maschine abgeworfenen und zeitweilig auf den Verdichtbalken fallenden Schotters ermöglicht. Mit der Anordnung einer Verstärkungsplatte ist eine vollflächige Befestigung des gewölbten Schopp-Balkens im Bereich der Trägerpfosten für eine hohe Belastbarkeit möglich.A preferred embodiment of the invention is characterized in that the Schopp beam has a convex curvature in cross-section, seen from top to bottom, the bottom edge of which in the front part of the curvature in the working direction and the top edge in the direction of compaction up to immediately near the threshold bottom edge is sufficient, with a reinforcing plate for attachment to the beam itself and to the support post connected above the machine frame is provided at the outer end. With the arched design of the Schopp beam, a large-scale attack on the thrown up ballast accumulations in the compaction or machine longitudinal direction is possible for their rapid displacement and compaction in the area below the sleepers. In addition, the curvature enables an immediate drainage of the ballast, which is continuously thrown off the ballast outlet of the machine and temporarily falls onto the compression beam. With the arrangement of a reinforcement plate, a full-surface fastening of the curved Schopp beam in the area of the support posts is possible for a high load capacity.

Die als durchgehender Schopp-Balken ausgebildete Verdichteinrichtung bzw. jeder Halbteil des Schopp-Balkens kann gemäß einer weiteren vorteilhaften Ausführungsvariante der Erfindung vorzugsweise mit einem Vibrationsantrieb verbunden sein. Durch den Vibrationsantrieb kann der Schopp-Balken zusätzlich zu der zyklischen Schlagbewegung in Vibrationen versetzt werden. Damit wird einerseits eine Erhöhung der Verdichtwirkung und andererseits ein noch rascheres Abfließen des auf den Schopp-Balken fallenden Schotters erreicht.According to a further advantageous embodiment of the invention, the compacting device or each half part of the Schopp bar, which is designed as a continuous Schopp bar, can preferably be connected to a vibration drive. Thanks to the vibration drive, the Schopp bar can be set to vibrate in addition to the cyclical stroke movement. On the one hand, this increases the compacting effect and, on the other hand, an even faster flow of the ballast falling on the Schopp beam.

Schließlich besteht noch eine weitere bevorzugte Ausführungsform der Erfindung darin, daß der als Schopp-Balken ausgebildeten Verdichteinrichtung eine am Maschinenrahmen angelenkte und in Arbeitsrichtung vorgeordnete, sowie über ein Spurkranzradpaar am Gleis abrollbare Niederhalte-Vorrichtung, vorzugsweise mit einem Höhenverstellantrieb, zugeordnet ist. Mit einer derartigen Niederhalte-Vorrichtung kann zusätzlich zum Gewicht des Gleises eine kontrollierte Kraft in Richtung zum Planum ausgeübt werden, so daß die Verdichtwirkung des Schopp-Balkens noch zusätzlich steigerbar ist. Außerdem wird mit der Niederhalte-Vorrichtung unter Vermeidung einer durch die Verdichtwirkung unkontrollierten Gleisanhebung eine genaue und gleichmäßige Fixierung des Gleises in der gewünschten Soll-Lage erreicht.Finally, a further preferred embodiment of the invention is that the compacting device designed as a Schopp bar is assigned a hold-down device, preferably with a height adjustment drive, which is articulated on the machine frame and arranged upstream in the working direction and can be unrolled via a pair of flange wheels on the track. With such a hold-down device, in addition to the weight of the track, a controlled force can be exerted in the direction of the level, so that the compacting effect of the Schopp beam is still can also be increased. In addition, with the hold-down device, avoiding an uncontrolled track elevation due to the compacting effect, an exact and uniform fixation of the track in the desired target position is achieved.

Räumkette 9 ist eine Arbeitskabine 13 oberhalb eines Aushubbereiches 14 der Schotterbettung mit dem Maschinenrahmen 10 verbunden. Dieser ist eine am Gleis 8 abrollbare Niederhalte-Vorrichtung 15 und eine Schotter-Verdichteinrichtung 16 nachgeordnet.The ballast bed cleaning machine 1 shown in FIG. 1 is composed of a total of three interconnected work vehicles 2, 3 and 4, which can be moved via rail carriages 5 on a track 8 formed from sleepers 6 and rails 7. On the middle work vehicle 3 connected to a drive, an endless conveyor or clearing chain 9, which is guided around the track 8, is fastened on a machine frame 10 with a drive. In the area of this conveyor or clearing chain 9, a height-adjustable track lifting device 11 is provided. In the working direction of the ballast bed cleaning machine 1 represented by an arrow 12, directly behind the conveyor or clearing chain 9, a work cabin 13 is connected to the machine frame 10 above an excavation area 14 of the ballast bed. This is followed by a hold-down device 15 that can be rolled off the track 8 and a ballast compacting device 16.

Am in Arbeitsrichtung vorderen Arbeitsfahrzeug 2 ist eine Siebanlage 17 mit zwei voneinander unabhängigen, in Maschinenlängsrichtung hintereinander V-förmig angeordneten, jeweils einen eigenen Vibrationsantrieb aufweisenden Siebeinheiten 18 auf einem Maschinenrahmen 19 angeordnet. Diese Siebanlage 17 ist durch ein mit kurzen Pfeilen dargestelltes Transportförderband 20 und zwei Einwurf-Förderbändern 21 mit dem durch die Förder- bzw. Räumkette 9 aufgenommenen verunreinigten Schotter beschickbar. Der in der Siebanlage 17 vom Schotter getrennte Abraum gelangt über ein mit strichpunktierten Pfeilen dargestelltes Abraum-Förderband 22 zum Beispiel auf einen vorgeordneten Verladewaggon. An der Unterseite der Siebanlage 17 ist der Anfang einer aus mehreren hintereinander angeordneten, mit langen Pfeilen dargestellten Förderbändern gebildeten Schotterverteileinrichtung 23 vorgesehen. Diese ist zum Transport, des gereinigten Schotters über einen Zwischenspeicher 24 zu einem im Bereich der Verdichteinrichtung 16 gelegenen ersten Schotterauslaß 25 und zu einem am hinteren Arbeitsfahrzeug 4 befindlichen zweiten Schotterauslaß 26 ausgebildet. Dieser zweite Schotterauslaß 26 ist durch einen Schotterspeicher 27 mit regelbaren Auslaßöffnungen gebildet. Der erste Schotterauslaß 25 ist zur Schaffung einer ersten Schotterschichte 28 zwischen Planum und Gleis 8 und der zweite Schotterauslaß 26 zur Schaffung einer zweiten, die Schwellenfächer ausfüllenden Schotterlage 29 vorgesehen. Am hinteren, dritten Arbeitsfahrzeug 4 ist ein Gleisstopf- und Hebe-Richtaggregat 30 über einen Antrieb in Fahrzeuglängsrichtung verschiebbar auf einem Maschinenrahmen 31 angeordnet. Die Schotterverteileinrichtung 23 ist durch ein dem Schotterspeicher 27 nachgeordnetes Förderband 32 bis über das hintere Maschinenende hinaus verlängerbar, wobei im vorderen, aufnahmeseitigen Endbereich des Förderbandes 32 ein verschwenkbares Umlenkorgan vorgesehen ist. Je nach der Stellung dieses Umlenkorganes ist wahlweise der gesamte Schotter bzw. ein Teil davon in den darunter befindlichen Schotterspeicher 27 bzw. als überschüssiger Schotter über das Förderband 32 zu einem nachfolgenden Verladewaggon umleitbar. Sämtliche Förderbänder sind zweckmäßigerweise rinnenförmig ausgebildet, wodurch auch bei langen Transportwegen ein seitliches Herabfallen von Schotter bzw. Abraum ausgeschlossen wird.On the front working vehicle 2 in the working direction, a screening plant 17 is arranged on a machine frame 19 with two independent screening units 18 which are arranged in a V-shape one behind the other in the machine longitudinal direction and each have their own vibration drive. This screening plant 17 can be fed with the contaminated ballast picked up by the conveyor or clearing chain 9 by means of a transport conveyor belt 20 shown with short arrows and two throw-in conveyor belts 21. The overburden separated from the ballast in the screening plant 17 passes, for example, to an upstream loading wagon via an overburden conveyor belt 22 shown with dash-dotted arrows. Provided on the underside of the screening plant 17 is the beginning of a ballast distributing device 23 formed from a plurality of conveyor belts arranged one behind the other and shown with long arrows. This is designed to transport the cleaned ballast via a buffer 24 to a first ballast outlet 25 located in the area of the compacting device 16 and to a second ballast outlet 26 located on the rear work vehicle 4. This second ballast outlet 26 is formed by a ballast accumulator 27 with controllable outlet openings. The first sho't terauslaß 25 is to create a first gravel layer 28 between ground level and platform 8 and the second gravel outlet 26 for creation of a second, the threshold compartments filling gravel layer 29th On the rear, third work vehicle 4, a track tamping and lifting straightening unit 30 is arranged on a machine frame 31 so as to be displaceable in the longitudinal direction of the vehicle via a drive. The ballast distributing device 23 can be extended by a conveyor belt 32 arranged downstream of the ballast store 27 to beyond the rear end of the machine, a pivotable deflection element being provided in the front, end region of the conveyor belt 32 on the receiving side. Depending on the position of this deflecting element, the entire ballast or a part thereof can optionally be diverted into the ballast store 27 located thereunder or as excess ballast via the conveyor belt 32 to a subsequent loading wagon. All of the conveyor belts are expediently channel-shaped, as a result of which lateral falling of ballast or overburden is prevented even with long transport routes.

Die in den Fig. 2 und 3 vergrößert dargestellte Schotter-Verdichteinrichtung 16 besteht aus vertikalen und seitlich des Gleises 8 angeordneten Trägerpfosten 33, die in einer Lagerstelle 34 um eine zur Fahrzeuglängsrichtung querverlaufende Achse 35 verschwenkbar am Maschinenrahmen 10 gelagert sind. Diese beiden gabelförmig ausgebildeten Trägerpfosten 33 sind in ihrem unteren Endbereich durch eine Verstärkungsplatte 36 verlängert, die mit dem Ende eines quer zum Gleis 8 angeordneten plattenförmigen Verdicht- oder Schopp-Balkens 37 verbunden ist. Die Verdichteinrichtung 16 ist direkt im Bereich des im ersten Schotterauslaß 25 abgeworfenen Schotters angeordnet. Ein mit dem Trägerpfosten 33 verbundener und am Maschinenrahmen 10 angelenkter Antrieb 38 ist für eine kontinuierliche, etwa in Gleisebene und in Gleislängsrichtung hin- und hergehende Pendelbewegung - für eine Vorverdichtung des Schotters entgegen der Arbeitsrichtung - ausgebildet. Die beiden gabelförmigen Enden des Trägerpfostens 33 sind durch eine Verbindungsplatte 39 miteinander verbunden. Der für ein Zusammenschieben des abgeworfenen Schotters schoppartig ausgebildete Verdichtbalken ist aus zwei zur Maschinenlängs-Symmetrieebene spiegelbildlich ausgebildeten Halbteilen 40 gebildet, die jeweils im Bereich des mit seinem oberen Ende am Maschinenrahmen befestigten Trägerpfostens 33 um eine vertikale Achse 41 nach außen zum Außereingriff außerhalb der Schwellen verschwenkbar gelagert und jeweils mit einem am Trägerpfosten 33 befestigten Antrieb 42 verbunden sind. Die vertikale Achse 41 ist durch eine in der Verbindungsplatte 39 drehbar gelagerten, mit dem unteren Ende mit der Verstärkungsplatte 36 und damit mit dem zugeordneten Halbteil 40 und mit ihrem oberen Ende mit dem Antrieb 42 verbundene Kurbelstange 43 gebildet. Die beiden Halbteile 40 des Schopp-Balkens 37 sind in ihrem freien, in Gleismitte gelegenen Endbereich durch eine lösbare Versteifungsplatte 44 miteinander verbunden. Der Schopp-Balken 37 weist im Querschnitt eine - von oben nach unten gesehen - konvexe Wölbung 45 auf, deren unterste Kante in dem in Arbeitsrichtung vorderen Teil der Wölbung 45 und deren oberste Kante in Verdichtrichtung bis unmittelbar nahe der Schwellenunterkante reicht. Jeder Halbteil 40 des Schopp-Balkens 37 ist mit einem Vibrationsantrieb 46 verbunden. Der Verdichteinrichtung 16 ist die an der Arbeitskabine 13 angelenkte und über ein Spurkranzradpaar 47 am Gleis 8 abrollbare Niederhalte-Vorrichtung 15 mit einem Höhenverstellantrieb 48 vorgeordnet. Die der Arbeitskabine 13 nachgeordneten Arbeitsaggregate und Bewegungsabläufe sind von einer zentralen Steuereinrichtung 49 aus steuerbar.The ballast compacting device 16 shown enlarged in FIGS. 2 and 3 consists of vertical support posts 33 arranged on the side of the track 8, which are pivotably mounted on the machine frame 10 in a bearing point 34 about an axis 35 running transversely to the longitudinal direction of the vehicle. These two fork-shaped support posts 33 are extended in their lower end region by a reinforcing plate 36 which is connected to the end of a plate-shaped compacting or Schopp beam 37 arranged transversely to the track 8. The compression device 16 is arranged directly in the region of the ballast thrown off in the first ballast outlet 25. A drive 38, which is connected to the support post 33 and is articulated on the machine frame 10, is designed for a continuous oscillating movement, for example reciprocating in the track plane and in the longitudinal direction of the track - for pre-compaction of the ballast against the working direction. The two fork-shaped ends of the support post 33 are connected to one another by a connecting plate 39. The one for pushing the thrown gravel together The compacting bar is formed from two half-parts 40 that are mirror images of the machine's longitudinal plane of symmetry, each of which is mounted in the area of the support post 33 which is fastened with its upper end to the machine frame about a vertical axis 41 to the outside for external engagement outside the sleepers and each with one on the support post 33 attached drive 42 are connected. The vertical axis 41 is formed by a crank rod 43 rotatably mounted in the connecting plate 39, with the lower end with the reinforcing plate 36 and thus with the associated half-part 40 and with its upper end with the drive 42. The two half parts 40 of the Schopp beam 37 are connected to one another in their free end region located in the middle of the track by a releasable stiffening plate 44. The Schopp bar 37 has in cross section a - from top to bottom - convex curvature 45, the lowermost edge of which extends in the front part of the curvature 45 in the working direction and the uppermost edge in the compacting direction up to immediately near the threshold lower edge. Each half part 40 of the Schopp bar 37 is connected to a vibration drive 46. The compacting device 16 is preceded by the hold-down device 15, which is articulated on the work cabin 13 and can be rolled off on the track 8 via a pair of flange wheels 47 and has a height adjustment drive 48. The work units and movement sequences downstream of the work cabin 13 can be controlled from a central control device 49.

Wie insbesondere in Fig. 3 ersichtlich, ist der erste Schotterauslaß durch eine schematisch angedeutete Schotterverteilschurre 50 mit zwei quer zur Gleislängsrichtung verlaufenden Auslässen zur Bildung zweier Schwellenauflagerbänke 51 gebildet. Zur Teilung des Schotters in eine erste, im ersten Schotterauslaß 25 abgeworfene Menge und in eine restliche, zum zweiten Schotterauslaß 26 transportierte Menge ist ein Umlenkorgan 52 vorgesehen. Dieses ist um eine quer zur Maschinenlängsrichtung verlaufende Achse verschwenkbar gelagert.As can be seen in particular in FIG. 3, the first ballast outlet is formed by a schematically indicated ballast distribution chute 50 with two outlets running transversely to the longitudinal direction of the track to form two sleeper support banks 51. A diverting element 52 is provided for dividing the ballast into a first quantity thrown off in the first ballast outlet 25 and into a remaining quantity transported to the second ballast outlet 26. This is pivotally mounted about an axis running transversely to the machine longitudinal direction.

Die Funktionsweise der in den Fig. 1 bis 3 dargestellten Schotterbett-Reinigungsmaschine 1 ist wie folgt:The method of operation of the ballast bed cleaning machine 1 shown in FIGS. 1 to 3 is as follows:

Während der kontinuierlichen Arbeitsvorfahrt der gesamten Schotterbett-Reinigungsmaschine 1 wird der verunreinigte Schotter kontinuierlich durch die Förder- bzw. Räumkette 9 auf das Transportförderband 20 hochgefördert und von diesem über die Einwurf-Förderbänder 21 auf die Siebanlage 17 abgeworfen. Der von dieser abgegebene gereinigte Schotter gelangt über die Schotterverteileinrichtung 23 entgegen der Arbeitsrichtung zum im Aushubbereich 14 gelegenen ersten Schotterauslaß 25. Dort wird - mit der in Fig. 2 ersichtlichen Stellung des Umlenkorganes 52 - ein Teil des transportierten Schotters über die Schotterverteilschurre 50 zwischen die Schwellen auf das Planum abgeworfen und ein weiterer Teil des Schotters über die nachgeordnete Schotterverteileinrichtung 23 dem zweiten Schotterauslaß 26 zugeführt. Der von diesem über den Schotterspeicher 27 abgeworfene Schotter wird unter Bildung einer zweiten Schotterlage 29 zur Füllung der Schwellenzwischenfächer verwendet. Sollte z. B. bei geringerem Abraumanteil mehr gereinigter Schotter vorliegen, so wird der nicht benötigte überschüssige Schotter unter entsprechender Verschwenkung eines oberhalb des Schotterspeichers 27 angeordneten Umlenkorganes über das nachgeordnete Förderband 32 zu einem nachfolgenden Verladewaggon weiterbefördert. Unmittelbar nach der Bildung der zweiten Schotterlage 29 erfolgt durch das Gleisstopf- und Hebe-Richtaggregat 30 eine kontinuierliche Gleislagekorrektur und Unterstopfung des Gleises.During the continuous work approach of the entire ballast bed cleaning machine 1, the contaminated ballast is continuously conveyed up through the conveyor or clearing chain 9 onto the transport conveyor belt 20 and is thrown from there via the throw-in conveyor belts 21 onto the screening plant 17. The cleaned ballast delivered by this passes via the ballast distribution device 23 against the working direction to the first ballast outlet 25 located in the excavation area 14. There - with the position of the deflection element 52 shown in FIG. 2 - part of the transported ballast via the ballast distribution chute 50 between the sleepers thrown onto the formation and a further part of the ballast is fed to the second ballast outlet 26 via the downstream ballast distribution device 23. The ballast thrown by it via the ballast store 27 is used to fill the intermediate sleeper compartments to form a second ballast layer 29. Should z. B. with less spoil content more cleaned ballast, then the excess ballast that is not required is conveyed on to a subsequent loading wagon by means of the downstream conveyor belt 32 with appropriate pivoting of a deflection member arranged above the ballast store 27. Immediately after the formation of the second ballast layer 29, the track tamping and lifting / straightening unit 30 continuously corrects the track position and tamping the track.

Der im ersten Schotterauslaß im Bereich der Verdichteinrichtung 16 abgeworfene Schotter zur Bildung der ersten Schotterschichte 28 wird durch die kontinuierlich hin- und hergehende, durch den Antrieb 38 bewirkte Bewegung schoppartig entgegen der Arbeitsrichtung unter die Schwellen 6 bewegt und vorverdichtet. In Fig. 2 ist die vorderste Position bei dieser hin- und hergehenden Bewegung in vollen Linien und die in Arbeitsrichtung hinterste Position mit strichpunktierten Linien dargestellt. Zur genauen Positionierung des Gleises 8 und zur Vermeidung einer unkontrollierten Anhebung durch die Verdichtwirkung der Verdichteinrichtung 16 wird die Niederhalte-Vorrichtung 15 mit ihrem Spurkranzradpaar 47 in die gewünschte Höhenposition gebracht. Die in der Arbeitskabine 13 befindliche Bedienungsperson kann mit der Hilfe der zentralen Steuereinrichtung 49 die Frequenz der Hin- und Herbewegung des Schopp-Balkens 37 wahlweise entsprechend der Schottermenge od. dgl. verändern. Bei Beendigung der Reinigungsarbeit werden die beiden Halbteile 40 des Schopp-Balkens 37 durch Betätigung der beiden Antriebe 42 von ihrer in Fig. 3 mit vollen Linien dargestellten Arbeitsposition um 90° in die mit strichpunktierten Linien dargestellte Ruheposition verschwenkt. Die Verschwenkung erfolgt dadurch, daß die in der Verbindungsplatte 39 drehbar gelagerte Kurbelstange 43 mitsamt der am unteren Ende befestigten Verstärkungsplatte ebenfalls um 90° verschwenkt wird. Anschließend können die seitlich des Gleises 8 ausgeschwenkten Halbteile 40 noch über das Gleisniveau gebracht werden, indem die Kolbenstange des Antriebes 38 zur Gänze in den Zylinder eingefahren wird.The ballast thrown off in the first ballast outlet in the area of the compacting device 16 to form the first ballast layer 28 is moved and precompressed under the sleepers 6 against the working direction by the continuously reciprocating movement caused by the drive 38. In Fig. 2, the foremost position in this reciprocating movement is shown in full lines and the rearmost position in the working direction with dash-dotted lines. In order to precisely position the track 8 and to avoid an uncontrolled raising due to the compacting effect of the compacting device 16, the hold-down device 15 with its flange wheel pair 47 is brought into the desired height position. With the help of the central control device 49, the operator located in the work cabin 13 can optionally change the frequency of the back and forth movement of the Schopp bar 37 in accordance with the amount of ballast or the like. At the end of the cleaning work, the two half parts 40 of the Schopp beam 37 are pivoted by actuation of the two drives 42 from their working position shown in full lines in FIG. 3 by 90 ° into the rest position shown in broken lines. The pivoting takes place in that the crank rod 43 rotatably mounted in the connecting plate 39 together with the reinforcing plate attached to the lower end is also pivoted through 90 °. Subsequently, the half-parts 40 swiveled out to the side of the track 8 can still be brought above the track level by completely retracting the piston rod of the drive 38 into the cylinder.

Eine in Fig. 4 dargestellte Schotterbett-Reinigungsmaschine 53 mit einem Maschinenrahmen 54 ist über Fahrwerke 55 auf einem aus Schienen 56 und Schwellen 57 gebildeten Gleis verfahrbar. Der über eine Förder- bzw. Räumkette 58 aufgenommene Schotter wird in einersiebanlage 59 gereinigt und über ein Abwurf-Förderband 60 durch das Gleis auf das Planum abgeworfen. Unmittelbar im Bereich des abgeworfenen Schotters ist eine Schotter-Verdichteinrichtung 61 vorgesehen. Diese besteht aus seitlich am Maschinenrahmen 54 um eine querverlaufende Achse verschwenkbar gelagerten Trägerpfosten 62, die durch einen ebenfalls am Maschinenrahmen 54 angelenkten Antrieb 63 in eine etwa in Gleisebene hin- und hergehende Bewegung versetzbar sind. Die unteren Enden der beiden Trägerpfosten 62 sind im Bereich unterhalb des Gleises durch einen plattenförmigen Verdichtbalken 64 mit einer konvexen Wölbung lösbar miteinander verbunden. Dieser Verdichtbalken 64 wird bei Beginn des Arbeitseinsatzes durch die vorbereitete Umbaulücke geschoben und mit den freien Enden der beiden Trägerpfosten 62 verbunden. Nach Beendigung des Arbeitseinsatzes erfolgt die Loslösung des Verdichtbalkens 64 von den Trägerpfosten 62, sodaß eine ungehinderte Überstellfahrt der Schotterbett-Reinigungsmaschine 53 durchführbar ist.A ballast bed cleaning machine 53 shown in FIG. 4 with a machine frame 54 is on chassis 55 a track formed from rails 56 and sleepers 57. The ballast picked up via a conveyor or clearing chain 58 is cleaned in a sieve system 59 and dropped onto the subgrade via the discharge conveyor belt 60 through the track. A ballast compacting device 61 is provided directly in the area of the thrown up ballast. This consists of support posts 62 which are mounted on the side of the machine frame 54 so as to be pivotable about a transverse axis, and which can be set into a movement which reciprocates approximately in the plane of the track by a drive 63 which is also articulated on the machine frame 54. The lower ends of the two support posts 62 are detachably connected to one another in the area below the track by a plate-shaped compression bar 64 with a convex curvature. This compacting bar 64 is pushed through the prepared gap at the start of the work and connected to the free ends of the two support posts 62. After completion of the work, the compression bar 64 is released from the support posts 62, so that an unobstructed transfer travel of the ballast bed cleaning machine 53 can be carried out.
