Description

Die Erfindung betrifft eine Stopfmaschine gemäß den im Oberbegriff der Ansprüche 1 und 2 angeführten Merkmalen sowie ein Verfahren.The invention relates to a tamping machine according to the features cited in the preamble of claims 1 and 2 and a method.

Derartige im Arbeitseinsatz kontinuierlich verfahrende Stopfmaschinen sind beispielsweise durch US 4 632 037 bekannt. Dabei liegt der besondere Vorteil darin, daß der eine wesentlich größere Masse aufweisende Maschinenrahmen nicht bei jeder zu unterstopfenden Schwelle gestoppt und anschließend sofort wieder beschleunigt werden muß. Die schrittweise Vorfahrt beschränkt sich auf den die Arbeitsaggregate tragenden Aggregatrahmen, der mit dem Maschinenrahmen verbunden und relativ zu diesem verschiebbar ausgebildet ist. Die Verschiebung erfolgt einerseits durch einen im Fahrwerk des Aggregatrahmens integrierten Fahrantrieb und andererseits durch einen Maschinen- und Aggregatrahmen miteinander verbindenden Hydraulikzylinder.Such tamping machines which continuously travel during operation are known, for example, from US Pat. No. 4,632,037. The particular advantage is that the machine frame, which has a much greater mass, does not have to be stopped at each threshold to be stuffed and then immediately accelerated again. The stepwise right of way is limited to the aggregate frame carrying the working units, which is connected to the machine frame and designed to be displaceable relative thereto. The shift takes place on the one hand by an integrated drive in the chassis of the unit frame drive and on the other hand by a machine and unit frame interconnecting hydraulic cylinder.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Maschine der gattungsgemäßen Art, mit der eine verbesserte Beschleunigung des Aggregatrahmens erzielbar ist.The object of the present invention is now to provide a machine of the generic type with which an improved acceleration of the unit frame can be achieved.

Erfindungsgemäß wird diese Aufgabe mit einer Maschine der eingangs genannten Art durch die im Kennzeichen von Ansprüchen 1 und 2 angeführten Merkmale gelöst.According to the invention this object is achieved by a machine of the type mentioned by the features cited in the characterizing part of claims 1 and 2.

Ein derartig ausgebildeter Beschleunigungsantrieb kommt quasi als Impulsgeber zur optimalen Unterstützung und Beschleunigung der Anfahrbewegung des Aggregatrahmens zur Wirkung. Nach der Anfangsbeschleunigung erfolgt die weitere Vorfahrt in optimaler Weise ausschließlich durch den im Fahrwerk des Aggregatrahmens integrierten Fahrantrieb.Such a trained accelerator drive comes as a kind of pulse for optimal support and acceleration of the starting movement of the unit frame to effect. After the initial acceleration takes place the further right of way in an optimal manner exclusively by the drive integrated in the chassis of the unit frame.

Weitere Vorteile und Ausbildungen der Erfindung ergeben sich aus den weiteren Ansprüchen und der Zeichnung.Further advantages and embodiments of the invention will become apparent from the other claims and the drawings.

Im folgenden wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben.In the following the invention will be described in more detail with reference to embodiments shown in the drawing.

a further embodiment in a schematic plan view.

Eine in Fig. 1 ersichtliche Stopfmaschine 1 weist einen Maschinenrahmen 2 auf, der endseitig je durch ein Schienenfahrwerk 3 auf einem aus Schwellen 4 und Schienen 5 gebildeten Gleis 6 verfahrbar ist. Dazu ist die Maschine mit einem Motor 7 und einem Fahrantrieb 8 ausgestattet. In einer Arbeitskabine 9 befindet sich eine Steuereinrichtung 10.An apparent in Fig. 1 tamping machine 1 has a machine frame 2, the end each by a rail chassis 3 on a rail 4 formed of sleepers 4 and rails 5 is movable. For this purpose, the machine is equipped with a motor 7 and a drive 8. In a work booth 9 is a control device 10th

Zwischen den beiden Schienenfahrwerken 3 des Maschinenrahmens 2 ist ein Aggregatrahmen 11 angeordnet, der an einem - bezüglich einer Arbeits- bzw. Maschinenlängsrichtung 12 - hinteren Ende 13 mit einem Fahrwerk 14 ausgestattet ist. An einem vorderen Ende 15 sind zwei in Maschinenquerrichtung einander gegenüberliegende Rahmenträger 16 vorgesehen, die in Rahmenabstützungen 17 längsverschiebbar gelagert sind. Unmittelbar vor dem mit einem eigenen Aggregatfahrantrieb 18 ausgestatteten Fahrwerk 14 ist ein Stopfaggregat 19 vorgesehen, das zur gleichzeitigen Unterstopfung von drei Schwellen 4 ausgebildet ist. Dem Stopfaggregat 19 ist ein -Gleishebeaggregat 20 vorgeordnet, beide Aggregate 19, 20 sind höhenverstellbar mit dem Aggregatrahmen 11 verbunden.Between the two rail bogies 3 of the machine frame 2, an assembly frame 11 is arranged, which is at a - with respect to a working or machine longitudinal direction 12 - 13 rear end equipped with a chassis 14. At a front end 15 two mutually transverse machine direction frame support 16 are provided, which are mounted longitudinally displaceable in frame supports 17. Immediately before the equipped with its own unit drive 18 chassis 14 a tamping unit 19 is provided, which is designed for the simultaneous Unterstopfung of three sleepers 4. The tamping unit 19 is a leveling unit 20 upstream, both units 19, 20 are height-adjustable connected to the unit frame 11.

Wie in Fig. 1 und 2 ersichtlich, ist zwischen hinterem Ende 13 des Aggregatrahmens 11 und dem Maschinenrahmen 2 ein als Hydraulikzylinder ausgebildeter Beschleunigungsantrieb 21 vorgesehen, der über eine Antriebsbefestigung 22 starr und ausschließlich mit dem Maschinenrahmen 2 verbunden ist. An einem freien Kolbenende 23 des Beschleunigungsantriebes 21 ist ein Abstützstempel 24 zur temporären Anlage am Aggregatrahmen 11 vorgesehen. Ein Maximalhub m des Beschleunigungsantriebes 21 beträgt vorzugsweise 800 mm und ist kleiner als ein maximaler Verschiebeweg a zwischen Maschinen- und Aggregatrahmen 2,11.As can be seen in FIGS. 1 and 2, an acceleration drive 21 designed as a hydraulic cylinder is provided between the rear end 13 of the unit frame 11 and the machine frame 2, which is rigidly and exclusively connected to the machine frame 2 via a drive attachment 22. At a free piston end 23 of the acceleration drive 21 is a Abstützstempel 24 is provided for temporary abutment on the unit frame 11. A maximum stroke m of the acceleration drive 21 is preferably 800 mm and is smaller than a maximum displacement a between the machine and unit frame 2,11.

Zur weiteren Unterstützung der Anfahrbeschleunigung des Aggregatrahmens 11 ist noch ein zweiter Beschleunigungsantrieb 25 mit einem Abstützstempel 26 vorgesehen, der über eine Antriebsbefestigung 27 mit dem Maschinenrahmen 2 verbunden ist. Ein Maximalhub dieses zweiten Beschleunigungsantriebes 25 beträgt lediglich 120 mm. Zwischen beiden Beschteunigungsantrieben 21, 25 ist ein Federpuffer 28 mit dem Maschinenrahmen 2 verbunden.To further support the starting acceleration of the unit frame 11, a second acceleration drive 25 is still provided with a Abstützstempel 26 which is connected via a drive attachment 27 to the machine frame 2. A maximum stroke of this second acceleration drive 25 is only 120 mm. Between the two Bescheunigungsantrieben 21, 25, a spring buffer 28 is connected to the machine frame 2.

Während sich der Maschinenrahmen 2 im Arbeitseinsatz kontinuierlich in Arbeitsrichtung 12 weiterbewegt, setzt sich die Bewegung des Aggregatrahmens 11 - in Relation zum Maschinenrahmen 2 - aus einer raschen Vorwärtsbeschleunigung und einem örtlichen Stillstand zu Durchführung einer Unterstopfung zusammen. Die Vorwärtsbeschleunigung erfolgt ausgehend von einer hinteren Endposition (in Fig.1 und 2 mit vollen Linien dargestellt) zu einer vorderen Endposition (s. strichpunktierte Linien). Um bei der Anfangsbeschleunigung den Aggregatfahrantrieb 18 zu unterstützen, erfolgt eine Beaufschlagung der beiden Beschleunigungsantriebe 21, 25. Diese drücken den Aggregatrahmen 11 in Richtung zur vorderen Endposition (s. Pfeil 30), wonach sich nach Erreichen des jeweiligen Maximalhubes die Abstützstempel 24, 26 automatisch vom Aggregatrahmen 11 lösen. Dieser wird schließlich mit Hilfe des Aggregatfahrantriebes 18 noch bis zur vorderen Endposition weiterbewegt (s. strichpunktierte Linie in Fig.1).While the machine frame 2 continues to move in the working direction 12 during work, the movement of the unit frame 11 - in relation to the machine frame 2 - is composed of a rapid forward acceleration and a local standstill to carry out a clogging. The forward acceleration takes place from a rear end position (shown in solid lines in FIGS. 1 and 2) to a front end position (see dash-dotted lines). In order to support the aggregate travel drive 18 during the initial acceleration, the two acceleration drives 21, 25 are pressed in. These press the aggregate frame 11 in the direction of the front end position (see arrow 30), after which the support punches 24, 26 automatically reach the respective maximum stroke from the unit frame 11. This will eventually with the help of the aggregate drive 18 still moved to the front end position (see dash-dotted line in Figure 1).

Durch den örtlichen Stillstand des Aggregatrahmens 11 während der Unterstopfung kommt es zu einer allmählichen Anlage des in der vorderen Endstellung befindlichen Abstützstempels 24 an den Aggregatrahmen 11, der in weiterer Folge eine mit dem Abstützstempel 24 verbundene, in einer drucklosen Schwimmstellung befindliche Kolbenstange 29 in die Ausgangsstellung zurückbewegt. Analog dazu wird auch der zweite Abstützstempel 26 zurückbewegt. Sobald die hintere Endposition des Aggregatrahmens 11 erreicht ist, beginnt unter Beaufschlagung der beiden Beschleunigungsantriebe 21, 25 und des Aggregatfahrantriebes 18 wiederum ein neuer Verschiebezyklus für den Aggregatrahmen 11.Due to the local standstill of the unit frame 11 during the Unterstopfung there is a gradual contact of the located in the front end position Abstützstempels 24 to the unit frame 11, which subsequently connected to the Abstützstempel 24, located in a non-pressurized floating position piston rod 29 in the starting position moved back. Similarly, the second Abstützstempel 26 is moved back. Once the rear end position of the unit frame 11 is reached, under the action of the two acceleration drives 21, 25 and the aggregate drive 18 again begins a new shift cycle for the unit frame 11th

In Fig. 4 ist schematisch eine weitere Ausführungsform der Erfindung dargestellt, bei der die Beschleunigungsantriebe 21,25 auf dem Aggregatrahmen 11 befestigt sind und die Abstützstempel 24 sich am Maschinenrahmen 2 abstützen. FIG. 4 schematically shows a further embodiment of the invention, in which the acceleration drives 21, 25 are fastened on the unit frame 11 and the support punches 24 are supported on the machine frame 2.
