Eine derartige Maschine ist beispielsweise durch US 5 357 867 bekannt. Die im Rahmen einer Gleiserneuerung zu entfernenden alten Schwellen werden durch die Schwellenaufnahmevorrichtung von der Schotterbettung abgehoben und auf der Maschine zwischengelagert. Die vorerst durch die Schwellenkufen erfaßte Schwelle wird mittels einer verschwenk- und höhenverstellbaren Gabel erfaßt, angehoben und mit der Schwellenunterseite auf ein Mitnahmeorgan der endlosen Transportkette abgelegt. Diese transportiert schließlich die Schwelle zu der höher gelegenen Schwellentransporteinheit.Such a machine is known for example from US 5,357,867.

This is about a drive 6 having caterpillar track 7 in a working direction 8 movable.

Die Schwellenaufnahmevorrichtung 1 besteht aus einer endlosen, mit Mitnahmeorganen 9 verbundenen, ein oberes und ein unteres Umlenkende 10, 11 aufweisenden Transportkette 12, der ein Rotationsantrieb 13 zugeordnet ist. Die Transportkette 12 ist in bezug auf eine durch die Umlenkenden 10,11 definierte Bezugslinie 30 in einem Winkel α zu einer Schotterbettung 14 geneigt angeordnet, der kleiner als 90° ist, wobei das untere Umlenkende 11 in Arbeitsrichtung 8 vor dem oberen Umlenkende 10 positioniert ist. Ein Abstand a zwischen zwei benachbarten Mitnahmeorganen 9 beträgt wenigstens das Zweifache einer Schwellenbreite b.The threshold receiving device 1 consists of an endless, with entrainment organs 9 connected, an upper and a lower deflecting 10, 11 having transport chain 12, which assigns a rotary drive 13 is. The transport chain 12 is with respect to a through the deflecting 10,11 defined reference line 30 inclined at an angle α to a ballast bed 14 arranged, which is smaller than 90 °, wherein the lower deflecting end 11 in Working direction 8 is positioned in front of the upper deflection end 10. A distance a between two adjacent entrainment organs 9 is at least the Twice a threshold width b.

Unterhalb des unteren Umlenkendes 11 befinden sich zwei in Schwellenlängsrichtung voneinander distanzierte Schwellenkufen 15, die durch eine in Maschinenlängsrichtung und parallel zur Transportkette 12 verlaufende Schwellengleitbahn 16 verlängert sind. Diese weist ein im Bereich eines Aufnahmeendes 17 einer Schwellentransporteinheit 18 gelegenes Übergabeende 19 auf. Below the lower deflection end 11 are two in the threshold longitudinal direction distanced from each other threshold skids 15, by a in Machine longitudinal direction and parallel to the transport chain 12 extending Threshold slide 16 are extended. This has in the range of a receiving end 17 a threshold transport unit 18 located transfer end 19 on.

Im Bereich des unteren Umlenkendes 11 und oberhalb der Schwellenkufen 15 ist ein Schwellenschieber 20 vorgesehen, der durch Antriebe 21, 22 um eine Achse 23 verschwenkbar bzw. in Maschinenlängsrichtung verschiebbar ist. Die Achse 23 verläuft mormal zur Maschinenlängsrichtung sowie horizontal. Ein durch die Schwellengleitbahn 16 und eine Kufengleitfläche 24 der Schwellenkufen 15 eingeschlossener Winkel β liegt vorzugsweise in einem Bereich von 130° bis 160°.In the area of the lower deflection end 11 and above the threshold skids 15 is a threshold slide 20 is provided by drives 21, 22 to an axis 23 pivotable or displaceable in the machine longitudinal direction is. The axis 23 is normal to the machine longitudinal direction and horizontal. A through the Schwellengleitbahn 16 and a Kufengleitfläche 24 of Threshold skids 15 included angle β is preferably in one Range from 130 ° to 160 °.

Im Arbeitseinsatz werden die Schwellenkufen 15 in einer kontinuierlichen Vorfahrt der Maschine 5 unter eine Schwellenunterseite 25 der zu entfernenden Schwelle 2 geschoben. Parallel dazu wird der Schwellenschieber 20 durch die Antriebe 21, 22 angehoben, nach vorne geschoben und unmittelbar vor der vorgeordneten Schwelle 2 abgesenkt (in vollen Linien dargestellte Position). Anschließend wird der Schwellenschieber 20 mitsamt der Schwelle 2 in Richtung zur Schwellengleitbahn 16 zurückgeschoben (s. strichpunktierte Schwelle). Inzwischen kommen durch eine Rotation der Transportkette 12 Mitnahmeorgane 9 zur Anlage an eine vordere Schwellenseitenfläche 26 und schieben damit die Schwelle 2 in einer durch einen Pfeil 27 aufgezeigten Richtung die Schwellengleitbahn 16 entlang. Dieser Zyklus zur Schwellenaufnahme wiederholt sich unter kontinuierlicher Vorfahrt der Maschine 5, während parallel durch permanente Rotation der Transportkette 12 die auf der Schwellengleitbahn 16 befindlichen Schwellen 2 in Richtung zum Aufnahmeende 17 transportiert werden. Sobald dieses erreicht ist, wird eine Umlenkklappe 28 um eine normal zur Maschinenlängsrichtung verlaufende Achse 29 verschwenkt und damit die Schwelle 2 auf das Aufnahmeende 17 befördert.In labor, the threshold skids 15 are in a continuous Advance of the machine 5 under a threshold bottom 25 of the to be removed Threshold 2 pushed. In parallel, the threshold slider 20 lifted by the drives 21, 22, pushed forward and immediately lowered before the upstream threshold 2 (shown in full lines Position). Subsequently, the threshold slider 20 together with the threshold 2 pushed back towards the Schwellengleitbahn 16 (see dot-dash line Threshold). Meanwhile come by a rotation of the transport chain 12th Mitnahmeorgane 9 for engagement with a front threshold side surface 26 and push so that the threshold 2 in an indicated by an arrow 27 Direction the Schwellengleitbahn 16 along. This cycle for threshold recording Repeats with continuous right of way of the machine 5, while parallel by permanent rotation of the transport chain 12 on the Schwellengleitbahn 16 located sleepers 2 toward the receiving end 17 are transported. Once this is achieved, a flapper 28 about a normal to the machine longitudinal axis 29 pivots and thus the threshold 2 transported to the receiving end 17.

Ein besonderer Vorteil dieser Schwellenaufnahmevorrichtung 1 liegt darin, daß bei entsprechend rascher Vorfahrt der Maschine 5 problemlos eine zweite Schwelle 2 auf die Kufengleitfläche 24 schiebbar ist und beide Schwellen 2 gemeinsam durch ein Mitnahmeorgan 9 hochtransportierbar sind.A particular advantage of this threshold pick-up device 1 is that that at a correspondingly fast right of way of the machine 5 easily a second Threshold 2 is slidable on the Kufengleitfläche 24 and both sleepers 2 together are highly transportable by a driving member 9.
