Description

Die Erfindung betrifft eine Maschine gemäß den Merkmalen des Oberbegriffes von Anspruch 1 sowie ein Verfahren zum gleichzeitigen Unterstopfen von vier Schwellen gemäß dem Oberbegriff des Anspruchs 3 und dem Oberbegriff des Anspruchs 4.The invention relates to a machine according to the features of the preamble of claim 1 and a method for simultaneous underfilling of four sleepers according to the preamble of claim 3 and the preamble of claim 4.

Durch US 5 706 734 ist ein derartiges Stopfaggregat bekannt, mit dem drei bzw. fünf hintereinander angeordnete Schwellen unterstopfbar sind. Dazu sind an jeder Schienenseite fünf Stopfpickelpaare positioniert, denen drei Vibrationsantriebe zugeordnet sind. Durch die dichte Aneinanderreihung der Stopfpickelpaare kann es allerdings Probleme bezüglich der ungehinderten Höhenverstellung der Stopfpickelpaare bzw. der Beistellbewegung der Stopfpickel geben. Diese sind teilweise in zwei einander entgegengesetzten Richtungen beizustellen.Such a tamping unit is known from US Pat. No. 5,706,734, with which three or five thresholds arranged one behind the other can be plugged. For this purpose, five pairs of stuffing needles are positioned on each rail side, to which three vibration drives are assigned. Due to the tight juxtaposition of the stuffing-needles pairs, however, there may be problems with respect to the unimpeded height adjustment of the stuffing-dough pairs or the additional movement of the stuffing picks. These are partly to be provided in two opposite directions.

Durch DE 15 34 022 ist es auch bekannt, zwei Stopfpickelpaare zur Unterstopfung von drei Schwellen hintereinander anzuordnen.From DE 15 34 022 it is also known to arrange two tufting pairs for the purpose of clogging three sleepers one behind the other.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Maschine der gattungsgemäßen Art, mit der insgesamt vier Schwellen in einer konstruktiv vereinfachten Art optimal unterstopfbar sind.The object of the present invention is now to provide a machine of the generic type, with a total of four sleepers are optimally unteropfbar in a structurally simplified manner.

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

Mit einer derartigen konstruktiven Lösung ist in vorteilhafter Weise eine dichte und damit wegen Bewegungseinschränkungen in bezug auf die Beistell- und Absenkbewegungen problematische Aneinanderreihung der Stopfpickelpaare vermeidbar. Trotz dieser lockeren Anordnung ist jedoch insofern eine gute Unterstopfung erzielbar, als bei vier aufeinanderfolgenden Schwellen je Schiene wenigstens ein Schwellenauflager zur Gänze unterstopfbar ist.With such a constructive solution, a dense and therefore because of movement restrictions with respect to the Beistell- and lowering movements problematic juxtaposition of Stopfpickelpaare be avoided in an advantageous manner. Despite this loose arrangement, however, is a good one Clogging can be achieved, as at four successive thresholds per rail at least one threshold support is completely unteropfbar.

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.

Eine in Fig.1 ersichtliche Maschine 1 zum Unterstopfen eines aus Schwellen 2 und Schienen 3 gebildeten Gleises 4 weist einen Maschinenrahmen 5 mit endseitig angeordneten Schienenfahrwerken 6 auf. Zwischen diesen ist ein Aggregatrahmen 7 positioniert, der an einem Ende 8 längsverschiebbar am Maschinenrahmen 5 angelenkt ist und sich am anderen Ende über ein Fahrwerk 9 am Gleis 4 abstützt. Ein Gleishebeaggregat 10 dient in Verbindung mit einem Bezugsystem 11 für die Gleislagekorrektur. Während im Arbeitseinsatz der Maschinenrahmen 5 in einer Arbeitsrichtung 12 kontinuierlich weiter fährt, wird der Aggregatrahmen 7 während des Stopfvorganges örtlich angehalten und anschließend für den nächsten Stopfvorgang rasch relativ zum Maschinenrahmen 5 zum nächsten Stopfbereich vorwärtsbewegt.A machine 1 shown in FIG. 1 for undercutting a track 4 formed from sleepers 2 and rails 3 has a machine frame 5 with rail carriages 6 arranged at the end. Between these an aggregate frame 7 is positioned, which is articulated longitudinally displaceable on one end 8 on the machine frame 5 and is supported at the other end via a chassis 9 on the track 4. A track lift unit 10 is used in conjunction with a reference system 11 for the track position correction. While in operation, the machine frame 5 continues to move continuously in one working direction 12, the unit frame 7 is stopped locally during the tamping process and then quickly moved forward relative to the machine frame 5 to the next stuffing area for the next stuffing operation.

Auf dem Aggregatrahmen 7 sind zwei in Maschinenquerrichtung voneinander distanzierte Stopfeinheiten 13 (siehe Fig.2 bzw. 3) angeordnet, die sich jeweils aus vier Stopfpickelpaaren 14,15,16,17 zusammensetzen. Jedes Stopfpickelpaar 14 - 17 besteht aus zwei mit Hilfe von Beistellantrieben 18 beistellbaren Stopfpickeln 19, die durch einen gemeinsamen Vibrationsantrieb 20 in Schwingungen versetzbar sind. Jeder Stopfpickel 19 ist zum Eintauchen in ein durch zwei benachbarte Schwellen 2 gebildetes Schwellenfach 26 vorgesehen.On the unit frame 7 two spaced apart in the cross machine direction stuffing units 13 (see Figures 2 and 3) are arranged, each one composed of four tufting pairs 14,15,16,17. Each stuffing pick 14 - 17 consists of two with the help of Beistellantrieben 18 can be placed stuffing pickles 19, which are displaceable by a common vibration drive 20 in vibration. Each tamping pick 19 is provided for immersion in a threshold pocket 26 formed by two adjacent sleepers 2.

Wie in Fig. 2 und 3 ersichtlich, sind die vier Stopfpickelpaare 14 bis 17 einer Stopfeinheit 13 in Maschinenlängsrichtung alternierend in einer bezüglich einer Maschinenmitte 21 kürzeren Distanz x und in einer längeren Distanz y positioniert. Damit können mit den zur Maschinenmitte 21 näher gelegenen Stopfpickelpaaren 15,17 einer Schieneninnenseite 22 benachbarte Schwellenauflager 23 unterstopft werden, während die restlichen Stopfpickelpaare 14,16 zur Verdichtung von einer Schienenaußenseite 24 benachbarten Schwellenauflagern 25 vorgesehen sind. Die Beistellantriebe 18 sind für eine vom jeweiligen Vibrationsantrieb 20 wegführende erste Beistellbewegung (s. Stopfrichtung 27 in Fig. 2) und eine gegengerichtete, zum Vibrationsantrieb 20 führende zweite Beistellbewegung (siehe Stopfrichtung 28 in Fig. 3) ausgebildet.As can be seen in FIGS. 2 and 3, the four pairs of stuffing picks 14 to 17 of a stuffing unit 13 are positioned alternately in the machine longitudinal direction at a shorter distance x and a longer distance y with respect to a machine center 21. Thus, with the closer to the machine center 21 Stopfpickelpaaren 15,17 a rail inside 22 adjacent Schwellenauflager 23 are supported, while the remaining Stopfpickelpaare 14,16 are provided for compression of a rail outside 24 adjacent Schwellenauflagern 25. The auxiliary drives 18 are designed for a first auxiliary movement leading away from the respective vibration drive 20 (see the tamping direction 27 in FIG. 2) and a counter-rotating second auxiliary movement leading to the vibration drive 20 (see tamping direction 28 in FIG.

Ein Stopfzyklus zur gleichzeitigen Unterstopfung von vier Schwellen setzt sich aus zwei Stopfvorgängen zusammen und wird folgendermaßen durchgeführt:A stuffing cycle for simultaneous clogging of four sleepers consists of two stuffing operations and is performed as follows:

In einem ersten Stopfvorgang (s. Fig. 2) werden die beide Stopfpickel 19 jedes Stopfpickelpaares 14 bis 17 zueinander bewegt (siehe Stopfrichtung 27), so daß jweils die dazwischen liegende Schwelle 2 unterstopft wird. Unmittelbar darauf erfolgt der zweite Stopfvorgang (s. Fig. 3), indem die Beistellbewegung der Beistellantriebe 18 in die Gegenrichtung umgekehrt wird und dadurch die im Schotter eingetauchten Stopfpickel 19 jedes Stopfpickelpaares 14 bis 17 voneinander bewegt werden (siehe Stopfrichtung 28). Damit wird jeweils das Schwellenauflager 23 bzw. 25 der zwischen zwei Stopfpickelpaaren 14 bis 17 liegenden Schwelle 2 verdichtet. Die vordersten bzw. hintersten Stopfpickel 19 verdichten dabei nur eine Hälfte des jeweiligen Stopfauflagers 23 bzw. 25. Die andere Hälfte wurde bereits im vorhergehenden Stopfzyklus unterstopft bzw. wird im nächsten Stopfzyklus nach Vorwärtsbewegung des Aggregatrahmens 13 um den vierfachen Schwellenabstand (A) verdichtet.In a first stuffing process (see Fig. 2), both tamping 19 each Stopfpickelpaares 14 to 17 are moved to each other (see Stopfrichtung 27), so that in each case the intervening threshold 2 is supported. Immediately thereafter, the second stuffing operation (see Fig. 3) by the Beistellbewegung the Beistellantriebe 18 is reversed in the opposite direction and thereby the stuffing tampons 19 immersed in the ballast each Stopfpickelpaares 14 to 17 are moved from each other (see Stopfrichtung 28). Thus, each of the threshold support 23 and 25 of the two tamping pairs 14 to 17 lying threshold 2 compacted. The foremost or rearmost tamping knobs 19 compress only one half of the respective Stopfauflagers 23 and 25. The other half was already stuffed in the previous Stopfzyklus or in the next Stopfzyklus after forward movement of the unit frame 13 by four times the threshold distance (A) compacted.

Wie in Fig. 4 ersichtlich, werden im ersten Stopfvorgang insgesamt pro Schienenseite vier Schwellenauflager 23,25 komplett verdichtet (siehe horizontale Linien). Im darauffolgenden zweiten Stopfvorgang werden zwei Schwellenauflager 23,25 durch eine gegenläufige Beistellrichtung komplett und vier Schwellenauflager 23,25 je zur Hälfte unterstopft (siehe vertikale, volle Linien). Die strichlierten Linien zeigen jene halb bzw. komplett unterstopften Schwellenauflager 23,25 an, die bereits beim vorhergehenden Stopfzyklus verdichtet wurden.As can be seen in FIG. 4, four threshold supports 23, 25 are completely compressed per rail side in the first stuffing operation (see horizontal lines). In the subsequent second stuffing operation, two threshold supports 23, 25 are completely supported by an opposite supply direction and four threshold supports 23, 25 are supported in half (see vertical, solid lines). The dashed lines indicate those semi or fully stuffed threshold supports 23, 25 that have already been compacted during the previous stuffing cycle.

Im dargestellten Beispiel weist jeder mit einem Beistellantrieb 18 verbundene Stopfhebel 29 lediglich einen einzigen Stopfpickel 19 auf. Wahlweise können jedoch ebenso in beispielsweise durch US 4 476 786 bekannter Weise zwei Stopfpickel 19 am Stopfhebel 29 befestigt sein. Erfindungsgemäß wäre es auch möglich, den ersten Stopfvorgang durch eine erste sowie in Querrichtung gegenüberliegende zweite Stopfeinheit, und den zweiten Stopfvorgang durch eine nachfolgende dritte und vierte Stopfeinheit durchzuführen.In the example shown, each associated with a Beistellantrieb 18 stuffing lever 29 only a single tamping 19. Optionally, however, two tamping knobs 19 may also be attached to the tamping lever 29 in, for example, US Pat. No. 4,476,786. According to the invention, it would also be possible to perform the first stuffing operation by a first and in the transverse direction opposite second stuffing unit, and the second stuffing process by a subsequent third and fourth stuffing unit.
