Description

Die Erfindung betrifft eine verfahrbare Gleisbaumaschine zum Reinigen des Schotters der unter einem Gleis befindlichen Schotterbettung, mit einer Räumeinrichtung zur Aufnahme von unter dem Gleis befindlichen Schotter, Reinigungseinrichtungen zum Reinigen des Schotters, Einbaueinrichtungen zum Einbauen des gereinigten Schotters unter das Gleis, mit einer ersten Förderanlage von der Räumeinrichtung zu den Reinigungseinrichtungen, einer zweiten Förderanlage von den Reimgungseinrichtungen zu den Einbaueinrichtungen, wobei die Reinigungseinrichtungen mindestens eine Trennanlage um Abtrennen der Schmutzteile vom Schotter enthalten.The invention relates to a movable track construction machine for cleaning the ballast of the gravel bed located under a track, with a clearing device for receiving under the track Gravel, cleaning equipment for cleaning the ballast, installation equipment for installing the cleaned ballast under the track, with a first conveying system from the clearing device to the cleaning devices, a second conveyor of the rhyming devices to the installation equipment, wherein the cleaning means at least one Separating plant to separate the dirt particles from the ballast.

Derartige Gleisbaumaschinen sind durch US 4 113 388 bekannt und werden eingesetzt, wenn der Unterbau oder die Schotterbettung von Gleisen saniert werden soll. Mit einer Räumeinrichtung wird - in der Regel unter dem in diesem Bearbeitungsbereich angehobenen Gleis - der verschmutzte und damit stumpfe Schotter aufgenommen, anschließend wird der kontaminierte Schotter in der Maschine Reinigungseinrichtungen zugeführt und anschließend wieder - in der Maschine - Einbaueinrichtungen zugeführt, welche das gereinigte Material dann wieder unter den Schwellen des angehobenen Gleises abgeben und verdichten. Gegebenenfalls wird der gereinigte Schotter gebrochen, und der gebrochene Schotter wird wieder unter das Gleis eingebaut. Alternativ kann auch frischer Schotter hinzugegeben werden, bevor das Gleisrost endgültig abgelegt und in der Schotterbettung befestigt wird.Such track laying machines are known from US 4,113,388 and are used when the substructure or the gravel bedding of tracks should be rehabilitated. With a clearing device is - usually below that in this editing area lifted track - the soiled and with it blunt gravel was added, then the contaminated Gravel fed into the machine cleaning equipment and then again - in the machine - fed installation equipment, which then the cleaned material again under the thresholds of deliver and compact the raised track. If necessary, the cleaned gravel is broken, and the broken gravel becomes re-installed under the track. Alternatively it can be fresher Gravel be added before the track rust finally deposited and is fixed in the ballast bed.

Aufgabe der Erfindung ist es, eine Gleisbaumaschine der eingangs genannten Art derart weiterzubilden, daß auch besonders stark verschmutzter Schotter wirksam und prozesssicher gereinigt wird und wieder eingebaut werden kann.The object of the invention is to provide a track construction machine of the initially so-called type in such a way that also very heavily polluted Ballast is effectively and reliably cleaned and reinstalled can be.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Gleisbaumaschine mit dem Merkmalen von Anspruch 1.This task will According to the invention solved by a track construction machine with the features of claim 1.

Die Vorteile der Erfindung liegen insbesondere darin, daß zum Reinigen des stark verschmutzten Schotters eine spezielle zum Einsatz kommt, welche mehrere parallele antreibbare Wellen aufweist, die Formkränze oder Formscheiben tragen, welche mit ihren radial auswärts gerichteten Formansätzen gegen die verschmutzten Schottersteine anarbeiten und diese durch eine Schlagbewegung von den Schmutzpartikeln befreien. Die Wellen mit ihren Formkränzen oder Formscheiben bilden ein Schlagwalzenbett, auf dem die Schottersteine vom Einlaß bis zum Auslaß der Trennanlage bearbeitet und gereinigt werden. The advantages of the invention are, in particular, that for cleaning of the heavily polluted gravel a special one is used, which has a plurality of parallel driven shafts, the wreaths or discs wear, which with their radially outwardly directed mold approaches against the polluted Work on ballast stones and make them by a flapping motion of free the dirt particles. The waves with their wreaths or forming discs form a beater roll bed on which the ballast stones processed and cleaned from the inlet to the outlet of the separation plant become.

Die radial nach außen gerichteten Formansätze sind in Achsrichtung der Wellen schmal und weisen je einen vorgegebenen Abstand von den benachbarten Formansätzen auf derselben Welle auf, sie bilden also zwischen sich jeweils einen Freiraum. Die Formansätze sind an einem Formkranz angeformt, der auch einstückig mit der Welle ausgebildet sein kann. Die Formansätze lassen sich auch radial an schmalen Formscheiben ausbilden, welche auf die Wellen - in vorgegebenem Abstand - aufgezogen sind. Der Freiraum zwischen ber achbarten Formkränzen oder Formscheiben besitzt eine axiale Breite, welche derjenigen eines Formkranzes oder einer Formscheibe entspricht. Auf diese Weise ist es möglich, daß zwischen zwei benachbarten Formkränzen oder Formscheiben jeweils eine Formscheibe hineinragt, die auf einer benachbarten Welle sitzt und von dieser benachbarten Welle in Bewegung gehalten wird. Benachbarte Wellen sind - in Achsrichtung - um die axiale Breite eines Formkranzes oder einer Formscheibe versetzt angeordnet. Der Abstand der Wellen voneinander ist so bemessen, daß die Formansätze der einen Welle - aufgrund des axialen Versatzes - in die Freiräume zwischen benachbarten Formkränzen oder Formscheiben der benachbarten Welle greifen. Zwischen einer Welle und den Formansätzen der anderen Welle ist ausreichend Spaltraum vorhanden, so daß kleinteilige Schmutzpartikel durch diesen Spaltraum hindurchfallen können, daß jedoch Schotter am Durchtritt durch den Spaltraum gehindert ist. Bei Rotation der Wellen erfahren die Schottersteine von den rotierenden Formansätzen daher eine heftige Schlagbewegung, die bewirkt, daß an den Schottersteinen anhaftende Schmutzteilchen sich lösen und durch den Spaltraum zwischen den rotierenden Wellen nach unten fallen. Die Schottersteine werden dann - in gereinigtem Zustand - am Auslaß der Trennanlage wieder auf ein Förderband gegeben und können dann weiterverarbeitet werden.The radially outwardly directed form approaches are in the axial direction of the Waves narrow and each have a predetermined distance from the adjacent Form approaches on the same wave, so they form between each have a free space. The form approaches are on a form wreath molded, which may also be integrally formed with the shaft. The shape approaches can also be formed radially on narrow forming disks, which on the waves - at a predetermined distance - raised are. The free space between overhanging wreaths or forming disks has an axial width which of that of a mold rim or a form of disc corresponds. In this way it is possible that between two adjacent molding rings or molding disks respectively protrudes a molding disc, which sits on an adjacent shaft and is kept moving by this adjacent wave. neighboring Shafts are - in the axial direction - around the axial width of a Molded rim or a form of disc arranged offset. The distance The waves of each other is so dimensioned that the shape approaches the a wave - due to the axial offset - in the free spaces between adjacent molding rings or shaping disks of the adjacent ones Wave grab. Between a wave and the form approaches of other wave is sufficient gap space available, so that small-scale Dirt particles can fall through this gap, but that gravel is prevented from passing through the gap. As the waves rotate, the ballast stones experience the rotation Form approaches therefore a violent flapping motion that causes that adhering to the ballast dirt particles dissolve and down through the gap between the rotating shafts fall. The gravel stones are then - in a purified state - placed back on a conveyor belt at the outlet of the separation plant and can then be further processed.

Die Umfangskontur der Formansätze und die axiale Breite der Formansätze ist so gestaltet und bemessen, daß die Schottersteine bei einer Rotation der Welle von den rotierenden Formansätzen nach oben mitgenommen werden. Es bildet sich auf diese Weise ein Schlagwalzenbett, bei dem die Formansätze benachbarter Wellen kammartig ineinandergreifen und verhindern, daß größere Schottersteine nach unten gelangen und zwischen den Formansätzen benachbarter Wellen die Rotationsbewegung der Wellen blockieren. Ein derartiges "Sternsieb" sorgt für eine heftige Schlagbewegung auf die Schottersteine und bewirkt, daß auch beispielsweise durch Feuchtigkeit besonders stark haftender Schmutz, Lehm oder dergleichen von den Schottersteinen abfällt und durch den Spaltraum zwischen den Formansätzen dann unter die Trennanlage auf eine dritte Förderanlage gelangen kann, welche die Schmutzteilchen dann einem Transportbehälter oder einem separaten Verladewagen zuführt.The circumferential contour of the form approaches and the axial width of the form approaches is designed and sized so that the gravel stones at a rotation of the shaft of the rotating form approaches to be taken upstairs. It forms in this way a beater roll bed, in which the shape approaches adjacent waves mesh like a comb and prevent larger ballast stones from coming down and between the form approaches of adjacent waves, the rotational movement of Block waves. Such a "star screen" makes for a violent Impact on the ballast stones and causes, for example Moisture, loam or the like, which adheres particularly strongly to moisture from the ballast stones and through the gap between the form approaches then pass under the separation plant on a third conveyor then the debris can be transported to a transport container or one feeds to separate loading vehicles.

Gemäß einer bevorzugten Ausführungsform der Erfindung sind der Trennanlage noch weitere Reinigungseinrichtungen, beispielsweise ein Rüttelsieb, nachgeordnet, welches eine Feinabsiebung durchführt und durch eine Rüttelbewegung insbesondere die kleineren Schmutzteilchen noch von den Schottersteinen abtrennt.According to a preferred embodiment of the invention, the separation plant still further cleaning devices, for example a vibrating screen, downstream, which performs a fine screening and by a shaking movement especially the smaller dirt particles still from the ballast stones separates.

Gemäß einer Ausführungsform der Erfindung ist es möglich, der Siebvorrichtung oder der Trennanlage eine Brecheranlage nachzuordnen, welche den Schotter scharfkantig macht und anschließend die gewünschte Korngröße aussiebt. Der aufbereitete Schotter läßt sich dann wieder zu den Einbaueinrichtungen zurücktransportieren, welche den aufbereiteten Schotter - gegebenenfalls mit neuem Schotter gemischt - wieder unter die Schwellen des angehobenen Gleises abgeben und verdichten.According to one embodiment of the invention, it is possible for the screening device or the separation plant nachordnen a crusher, which makes the gravel sharp-edged and then the desired grain size winkles. The processed gravel can then be returned to the Transport back built-in equipment, which processed the Gravel - possibly mixed with new gravel - again under deliver and compact the sleepers of the raised track.

Mittels Gleishebe-Einrichtungen (nicht dargestellt) wird das Gleis, auf dem die Gleisbaumaschine fährt, und dessen Schotterbettung gereinigt und gegebenenfalls auch erneuert werden soll, im Bereich der Brücke 3 angehoben. Eine Räumeinrichtung 6 ist an der Brücke 3 angebracht und dient zur Aufnahme einer unter den Schwellen befindlichen Materialschicht, die im wesentlichen aus Schotter besteht. Unter der Schotterbettung befindet sich eine Zwischenschicht aus Schotter und stark kontaminiertem Sand und darunter liegt die Planumsschutzschicht. An der Brücke 3 ist ferner eine Einbaueinrichtung 40 angeordnet, welche den zuvor mit der Räumeinrichtung 6 aufgenommenen Schotter nach seiner Reinigung und gegebenenfalls auch weiteren Bearbeitung wieder erhält und wieder unter das Gleis einbaut und dort mittels eines Verdichters verdichtet. An dem der Antriebseinheit 5 gegenüberliegenden Ende der Gleisbaumaschine lassen sich Verladewagen (nicht dargestellt) ankoppeln, welche bei der Reinigung oder Bearbeitung des Schotters anfallenden Abraum aufnehmen und/oder auch zusätzliche Einbaumaterialien, wie Schotter oder dergleichen, zuführen. On the work machine 2 more devices are arranged, the during the various work steps for the renewal of the track foundation be used. By means of track lifting devices (not shown) becomes the track on which the track-laying machine drives, and whose ballast bed cleaned and possibly also renewed is to be raised in the area of the bridge 3. A clearing device 6 is attached to the bridge 3 and serves to receive a Under the thresholds material layer, the substantially consists of gravel. Under the gravel bedding is a Intermediate layer of gravel and heavily contaminated sand and below lies the formation protection layer. At the bridge 3 is also a Installation device 40 is arranged, which previously with the clearing device 6 collected gravel after its purification and, where appropriate also receives further processing again and again under the track installed and compacted there by means of a compressor. At the drive unit Leave the opposite end of the track-laying machine dock loading vehicles (not shown), which in the cleaning or processing of the ballast accumulate overburden and / or additional paving materials, such as gravel or the like, respectively.

An die Arbeitsmaschine 2 ist eine Trennanlage 10 angekoppelt, die auf zwei Drehgestellen 12 und einem Rahmen 14 montiert ist und ebenfalls auf dem Gleis 1 verfahrbar ist. An die Trennanlage 10 ist - in der dargestellten Ausführungsform - eine Siebvorrichtung 30 angekoppelt, die ebenfalls auf Drehgestellen 32 und einem Rahmen 34 montiert ist und auf dem Gleis 1 verfahrbar ist.To the working machine 2, a separation system 10 is coupled, the on two bogies 12 and a frame 14 is mounted and also on the track 1 is movable. To the separation system 10 is - in the illustrated embodiment - a screening device 30 coupled which is also mounted on bogies 32 and a frame 34 and on the track 1 is movable.

Eine erste Förderanlage 50 verläuft von der Räumeinrichtung 6 über die Brücke 3 der Arbeitsmaschine bis zum Einlaß der Trennanlage 10 und vom Auslaß der Trennanlage 10 anschließend bis zu der Siebvorrichtung 30. Unterhalb der Siebvorrichtung 30 nimmt eine zweite Förderanlage 60 den gereinigten Schotter auf und verläuft über den Wagen der Trennanlage 10 und teilweise über die Brücke 3 zurück bis zu den Einbaueinrichtungen 40. Eine dritte Förderanlage 70 beginnt unterhalb der Trennanlage 10, läuft unter der Siebvorrichtung 30 hindurch und gegebenenfalls auf einen Verladewagen (nicht dargestellt), der an dem der Antriebseinheit 5 entgegengesetzten Ende an die Gleisbaumaschine ankoppelbar ist.A first conveyor 50 extends from the reamer 6 via the bridge 3 of the working machine to the inlet of the separation plant 10th and from the outlet of the separator 10 then to the screening device 30. Below the screening device 30 takes a second conveyor 60 on the cleaned gravel and runs over the car the separation system 10 and partly on the bridge 3 back to the Installation devices 40. A third conveyor 70 begins below the separator 10, passes under the screening device 30 therethrough and optionally on a loading trolley (not shown), the at the drive unit 5 opposite end to the track construction machine can be coupled.

Schotter, welcher von der Räumeinrichtung 6 aufgenommen wird, wird mittels der ersten Förderanlage 50 über die Brücke 3 zum Einlaß der Trennanlage 10 gefördert und dort in den Behälter 12 der Trennanlage 10 eingegeben. Am Auslaß der Trennanlage 10 übernimmt die erste Förderanlage 50 erneut den Schotter und verbringt diesen in das Rüttelsieb 30, welches den dann gereinigten Schotter auf die zweite Förderanlage 60 abgibt, die dann zurück zur Arbeitsmaschine 2 verläuft und den gereinigten Schotter den Einbaueinrichtungen 40 zuführt, welche den gereinigten Schotter unter das angehobene Gleis abgeben und dort verdichten.Gravel, which is received by the reamer 6, is by means of the first conveyor 50 via the bridge 3 to the inlet of Separator 10 promoted and there in the container 12 of the separation plant 10 entered. At the outlet of the separation unit 10 takes over the first conveyor 50 again the gravel and spends it in the vibrating screen 30, which then cleaned gravel on the second conveyor Sends off 60, which then goes back to the working machine 2 and the cleaned ballast feeds the installation means 40, which Put the cleaned gravel under the raised track and there compacted.

Wie insbesondere den Fin. 2, 3 und 4 entnehmbar ist, wird der verschmutzte Schotter über die Förderanlage 50 zuerst einer Trennanlage 10 zugeführt, die ein Schlagwalzenbett 14 aus mehreren parallelen Wellen 110 aufweist und eine umlaufende Seitenwandung 12 besitzt. As in particular the fin. 2, 3 and 4 can be removed, the polluted Gravel on the conveyor 50 first a separation plant 10, which is a beater bed 14 of several parallel Shafts 110 and has a circumferential side wall 12.

Die parallelen Wellen 110 werden von einem Antrieb (nicht dargestellt) angetrieben und sind in vorgegebenem Abstand a voneinander angeordnet und tragen jeweils mehrere Formscheiben 112, die in Achsrichtung der Wellen 110 eine geringe Breite aufweisen und in der dargestellten Ausführungsform eine sternförmige Kontur mit mehreren radialen Formansätzen 114 besitzen. Benachbarte Formscheiben 112 sind in Achsrichtung der Wellen 110 voneinander mit Abstand b angeordnet, der geringfügig größer als die Breiten c der Formscheiben 112 ist. Zwischen zwei benachbarten Formscheiben 112 bildet sich jeweils ein Freiraum der axialen Breite b. Benachbarte Wellen 110 sind mit einem axialen Versatz zur Breite b gelagert, so daß die Formscheiben 112 der einen Welle 110 jeweils in die Freiräume zwischen zwei Formscheiben 112 der Nachbarwelle 110 eingreifen.The parallel shafts 110 are driven by a drive (not shown) driven and are arranged at a predetermined distance a from each other and each carry a plurality of forming wheels 112, which in the axial direction of the Shafts 110 have a small width and in the illustrated embodiment a star-shaped contour with several radial form approaches 114 own. Adjacent form wheels 112 are in the axial direction the shafts 110 are spaced from each other by a distance b, which is slightly greater than the widths c of the forming wheels 112. Between two adjacent ones Shims 112 each form a free space of the axial Width b. Adjacent shafts 110 are at an axial offset stored to the width b, so that the forming wheels 112 of a shaft 110th each in the spaces between two forming wheels 112 of the neighboring wave 110 intervene.

Der Abstand a zwischen benachbarten Wellen 110 ist so bemessen, daß in radialer Richtung zwischen der einen Welle und den Formansätzen 114 der anderen Welle 110 ausreichend Spaltraum 116 vorhanden ist, so daß Schmutzpartikel durch das Bett 14 nach unten fallen können. Der Spaltraum 116 ist jedoch so klein, daß größere Schottersteine nicht durch den Spaltraum hindurchfallen. Die Breite der Formscheiben 112 - in Achsrichtung der Wellen 110 gemessen - ist bevorzugt so gering, daß bei Rotation der Wellen der jeweils sich nach oben bewegende Umfangsabschnitt die Schottersteine nach oben mitnimmt und auch aus den Zwischenräumen der nach unten laufenden Umfangsabschnitte der Formscheiben 112 heraus nach oben bewegt. Es wird dadurch verhindert, daß größere Schottersteine zwischen Formscheiben benachbarter Wellen 110 eingeklemmt werden und zu einer Blockade der Drehbewegung der Wellen 110 führen.The distance a between adjacent shafts 110 is dimensioned such that in the radial direction between the one shaft and the form approaches 114 of the other shaft 110 sufficient gap space 116 is present, so that dirt particles can fall through the bed 14 down. However, the gap 116 is so small that larger ballast stones do not fall through the gap. The width of the shape wheels 112 - measured in the axial direction of the shafts 110 - is preferred so small that upon rotation of the waves of each upward moving peripheral section the ballast stones upwards takes along and also from the spaces of the down-going Circumferentially sections of the forming wheels 112 moves upwards. It is prevented by that larger ballast stones between Forming disks of adjacent shafts 110 are clamped and closed cause a blockade of the rotational movement of the shafts 110.

Die nach unten durch die Schlagwalzen 14 hindurchfallenden Schmutzteile bzw. Kleinanteile des Schotters fallen auf die dritte Förderanlage 70 und werden in einem Transportbehälter oder einem angekoppelten Verladewagen (nicht dargestellt) abgefördert.The falling down through the impact rollers 14 dirt parts or small parts of the ballast fall on the third conveyor 70 and are docked in a transport container or one Verladewagen (not shown) carried away.
