Description

Die Erfindung betrifft ein Stopfaggregat zum Unterstopfen von Schwellen eines Gleises, mit einem höhenverstellbar auf einem Aggregatrahmen gelagerten Pickelträger, auf dem jeweils durch einen hydraulischen, eine Zylinderachse aufweisenden und mit einem Vibrationserreger verbundenen Beistellzylinder zueinander verschwenkbare, ein Stopfpickelpaar bildende Stopfpickel gelagert sind.The invention relates to a Stopfaggregat for Unterstopfen thresholds of a track, with a height-adjustable mounted on an aggregate frame pimple carrier, on each of which by a hydraulic, a cylinder axis and connected to a vibration exciter Beistellzylinder each other pivotable, a tamping pair forming tamping are stored.

Stopfaggregate zum Unterstopfen von Schwellen eines Gleises sind bereits vielfach bekannt, wie z. B. durch DE 830 352 C sowie US 4 240 352 , AT 339 358 , EP 0 331 956 oder US 4 068 595 . Die auf die Stopfpickel einwirkenden Vibrationen des Vibrationserregers können entweder durch eine Exzenterwelle oder durch hydraulische Impulse in einem Linearantrieb erzeugt werden, der gleichzeitig auch die Beistellbewegungen der Stopfpickel ausführt.Stopfaggregate to Unterstopfen thresholds of a track are already widely known, such. B. by DE 830 352 C such as US 4,240,352 . AT 339,358 . EP 0 331 956 or US Pat. No. 4,068,595 , The vibrations of the vibration exciter acting on the tamping picks can be generated either by an eccentric shaft or by hydraulic impulses in a linear drive, which at the same time also carries out the auxiliary movements of the tamping picks.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Stopfaggregates der eingangs genannten Art, mit dem eine verringerte Vibrationsbelastung des Aggregatrahmens erzielbar ist.The object of the present invention is now to provide a tamping unit of the type mentioned, with which a reduced vibration load of the unit frame can be achieved.

Diese Aufgabe wird erfindungsgemäß mit einem Stopfaggregat der gattungsgemäßen Art durch die im Kennzeichen des Hauptanspruches angeführten Merkmale gelöst.This object is achieved with a tamping unit of the generic type by the features cited in the characterizing part of the main claim.

Mit dieser Verbindung der beiden Beistellzylinder zu einer starren Konstruktionseinheit wird der besondere Vorteil erreicht, dass sich die durch den Vibrationserreger erzeugten Schwingungen der beiden Beistellantriebe großteils aufheben. Mit dem vertikal verstellbaren Gleitlager ist eine problemlose Beistellbewegung der Stopfpickel gewährleistet.With this compound of the two side cylinders to a rigid construction unit, the particular advantage is achieved that the vibrations generated by the vibration exciter of the two side drives largely cancel. With the vertically adjustable slide bearing a smooth Beistellbewegung the tamping is guaranteed.

Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen und der Zeichnungsbeschreibung.Further advantages of the invention will become apparent from the dependent claims and the drawing description.

Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigen: Fig. 1 eine Seitenansicht eines Stopfaggregates mit Stopfpickel zueinander bewegbaren Beistellantrieben, und Fig. 2, 3 je eine vergrößerte Darstellung der Beistellantriebe.In the following the invention will be described with reference to an embodiment shown in the drawing. Show it: Fig. 1 a side view of a Stopfaggregates with stuffing pick each other movable Beistellantrieben, and Fig. 2, 3rd depending on an enlarged view of the Beistellantriebe.

Ein in Fig. 1 dargestelltes Stopfaggregat 1 zum Unterstopfen von Schwellen eines Gleises weist zwei ein Stopfpickelpaar 10 bildende Stopfpickel 2 auf, die jeweils mithilfe eines Beistellantriebes 3 für eine Schotterverdichtung zangenartig zueinander bewegbar sind. Jeder Stopfpickel 2 ist um eine Schwenkachse 4 verschwenkbar auf einem relativ zu einem Aggregatrahmen 5 höhenverstellbaren Pickelträger 6 gelagert. Jedem eine Zylinderachse 7 aufweisendem Beistellantrieb 3 ist ein hydraulisch basierter Vibrationserreger 8 zur Erzeugung von einer Beistellbewegung der Stopfpickel 2 überlagerten Vibrationen zugeordnet.An in Fig. 1 illustrated Stopfaggregat 1 for Unterstopfen sleepers of a track has two a tamping pair 10 forming tamping pick 2, which are each with the aid of a Beistellantriebes 3 for a ballast compaction pliers like to each other movable. Each tamping pick 2 is mounted pivotably about a pivot axis 4 on a pommel carrier 6, which is height-adjustable relative to an aggregate frame 5. Each a cylinder axis 7 having Beistellantrieb 3 is assigned a hydraulically based vibration exciter 8 for generating a Beistellbewegung the tamping 2 superimposed vibrations.

Wie insbesondere in Fig. 2 und 3 ersichtlich, sind die beiden jeweils über eine Gelenkstelle 11 mit einem der beiden Stopfpickel 2 verbundenen Beistellantriebe 3 des Stopfpickelpaares 10 in ihrer Position zueinander unveränderlich zu einer Antriebseinheit 12 miteinander verbunden. Diese weist zwischen den beiden Gelenkstellen 11 ein Gleitlager 13 auf, das in einer mit dem Pickelträger 6 verbundenen Lagerführung 14 in vertikaler Richtung frei beweglich ist.As in particular in FIGS. 2 and 3 can be seen, the two in each case via a joint 11 with one of the two stuffing tamp 2 connected Beistellantriebe 3 of Stopfpickelpaares 10 in their position relative to each other unchangeable connected to a drive unit 12 with each other. This has between the two joints 11, a sliding bearing 13 which is freely movable in a direction connected to the pimple carrier 6 bearing guide 14 in the vertical direction.

Die Zylinderachsen 7 der beiden miteinander verbundenen Beistellantriebe 3 sind in einer gemeinsamen Linie bzw. koaxial angeordnet. Das Gleitlager 13 ist mittig zwischen den beiden Gelenkstellen 11 positioniert.The cylinder axes 7 of the two associated auxiliary drives 3 are arranged in a common line or coaxially. The sliding bearing 13 is positioned centrally between the two hinge points 11.

In einer alternativen Lösung der Erfindung wäre es insbesondere aus Platzgründen auch möglich, die Zylinderachsen 7 der beiden Beistellantriebe 3 in einem kleinen Winkel zueinander anzuordnen.In an alternative solution of the invention, it would also be possible in particular for reasons of space, to arrange the cylinder axes 7 of the two side drives 3 at a small angle to each other.
