Abstract

An ballast tamping assembly comprises four independently displaceable ballast tamping units arrayed in a line extending transversely to the machine frame elongation. Each ballast tamping unit comprises a carrier frame, a tamping tool carrier vertically adjustably mounted on the carrier frame, and a pair of vibratory tamping tools mounted on the tamping tool carrier for reciprocation in the track direction. Each vibratory tamping tool has a tamping pick remote from the carrier frame and pivotal about an axis extending in the direction of the machine frame elongation and connected to a pivoting drive, and another tamping pick immediately adjacent the carrier frame and fixedly connected to the tamping tool, the remote tamping pick being pivotal between two end positions delimited by respective stops, a first one of the end positions being immediately adjacent the other tamping pick for immersion of the tamping picks at one rail side and the second end position being remote from the other tamping pick for immersion of the tamping picks at respective rail sides. Independently operable drives are connected to the ballast tamping units for displacing the ballast tamping units in a direction extending transversely to the machine frame elongation.

Description

Die Erfindung betrifft ein Stopfaggregat für Gleisstopfmaschinen, mit insgesamt vier in Gleisquerrichtung nebeneinander angeordneten und durch Antriebe voneinander unabhängig querverschiebbaren Stopfeinheiten, die jeweils einen Aggregatrahmen mit einem höhenverstellbar gelagerten Werkzeugträger und zwei auf diesem gelagerte, in Maschinenlängsrichtung einander gegenüberliegende, vibrier- und beistellbare Stopfwerkzeuge aufweisen, wobei jedes Stopfwerkzeug mit einem durch einen Verschwenkantrieb um eine in Maschinenlängsrichtung verlaufende Schwenkachse verschwenkbaren Stopfpickel verbunden ist.The invention relates to a tamping unit for track tamping machines, with a total of four tamping units arranged next to one another in the transverse direction of the track and which can be displaced independently of one another by drives, each having an assembly frame with a height-adjustable tool holder and two tamping tools which are mounted opposite one another in the machine longitudinal direction and can be vibrated and provided. wherein each tamping tool is connected to a tamping pick which can be pivoted by a pivoting drive about a pivot axis running in the longitudinal direction of the machine.

Ein derartiges Stopfaggregat ist durch die US-PS 5,007,349 bekannt, wobei vier voneinander unabhängig querverschiebbare Stopfeinheiten auf einem drehbar am Maschinenrahmen einer Gleisstopfmaschine gelagerten Führungsrahmen angeordnet sind. Jede Stopfeinheit weist einen eigenen Aggregatrahmen auf, der mit einem höhenverstellbaren Werkzeugträger verbunden ist. Auf diesem sind jeweils zwei in Maschinenlängsrichtung einander gegenüberliegende, durch Antriebe vibrier- und beistellbare Stopfwerkzeuge gelagert. Diese sind wiederum mit je zwei in Maschinenquerrichtung nebeneinander liegenden Stopfpickeln zum Eintauchen in den an einer Schienenlängsseite gelegenen Schotterbereich ausgestattet. Durch den Einsatz von insgesamt vier voneinander unabhängigen Stopfeinheiten ist eine verbesserte Anpassung der Stopfpickelpositionen an den unregelmäßigen Schienenverlauf in Weichenbereichen möglich. Gemäß einer weiteren, in Fig. 7 dargestellten Variante dieser bekannten Lösung sind die Stopfpickel eines Stopfwerkzeuges jeweils um in Maschinenlängsrichtung verlaufende Achsen seitlich verschwenkbar gelagert und jeweils mit einem eigenen hydraulischen Seitenverschwenkantrieb verbunden. Eine derartige Lösung hat allerdings den Nachteil, daß die richtige Positionierung der einzeln verschwenkbaren, insgesamt 16 Stopfpickel einen beträchtlich erhöhten Zeit- und Konzentrationsaufwand für jeden einzelnen Stopfzyklus erfordert.Such a tamping unit is known from US Pat. No. 5,007,349, four tamping units which can be displaced independently of one another being arranged on a guide frame which is rotatably mounted on the machine frame of a track tamping machine. Each tamping unit has its own unit frame, which is connected to a height-adjustable tool holder. Two tamping tools that are opposite each other in the machine longitudinal direction and can be vibrated and provided by drives are mounted on this. These are each equipped with two tamping picks located next to each other in the cross-machine direction for immersion in the ballast area on one side of the rail. By using a total of four independent tamping units, an improved adaptation of the tamping pick positions to the irregular rail course in switch areas is possible. According to a further variant of this known solution, shown in FIG. 7, the tamping picks of a tamping tool are each pivoted laterally about axes running in the machine longitudinal direction and are each connected to their own hydraulic side pivoting drive. However, such a solution has the disadvantage that the correct positioning of the individually pivotable, total of 16 tamping axes requires a considerably increased expenditure of time and concentration for each individual tamping cycle.

Ein weiteres, durch die AT-PS 382 179 bekanntes Stopfaggregat setzt sich aus zwei voneinander unabhängigen Stopfeinheiten zusammen, die jeweils einen Aggregatrahmen mit zwei unabhängig voneinander höhenverstellbaren Werkzeugträgern aufweisen. Jeder dieser beiden Werkzeugträger ist mit einem zum Eintauchen an der linken bzw. rechten Schienenseite vorgesehenen Paar von Stopfwerkzeugen verbunden. An diesen sind wiederum um eine in Maschinenlängsrichtung verlaufende Schwenkachse verschwenkbare Stopfpickel befestigt. Damit kann beispielsweise ein außen liegender Stopfpickel bei einem Stopfhindernis so weit seitlich hochgeschwenkt werden, daß beim Absenken des Stopfwerkzeuges lediglich der nicht verschwenkte Innen-Stopfpickel in den Schotter eintaucht. Sind die an einer Schienenlängsseite gelegenen Stopfpickel einer Stopfeinheit wegen eines Stopfhindernisses überhaupt nicht mehr in den Schotter eintauchbar, so wird lediglich der zweite Werkzeugträger mitsamt den auf diesem gelagerten, der gegenüberliegenden Schienenseite zugeordneten Stopfpickeln abgesenkt. Eine derartige bekannte Lösung ist - ähnlich wie bei dem durch die US-PSen 4,537,135 und 3,534,687 bekannten Stopfaggregat - insofern nachteilig, als die Distanz zwischen den vier auf dem gemeinsamen Aggregatrahmen gelagerten Stopfwerkzeugen zur Anpassung an unterschiedlich distanzierte Stopfhindernisse nicht variierbar ist.Another tamping unit known from AT-PS 382 179 is composed of two independent tamping units, each of which has an assembly frame with two independently adjustable tool carriers. Each of these two tool carriers is connected to a pair of tamping tools provided for immersion on the left or right rail side. These are in turn around a machine running in the machine longitudinal direction Swiveling tamping ax attached to swivel axis. This means, for example, that an outside tamping pick can be swung up sideways so far that only the non-swung inside tamping pick plunges into the ballast when the tamping tool is lowered. If the tamping picks of a tamping unit located on a longitudinal side of the rail can no longer be immersed in the ballast due to a tamping obstacle, then only the second tool carrier is lowered together with the tamping picks mounted on it and assigned to the opposite rail side. Such a known solution - similar to the tamping unit known from US Pat. Nos. 4,537,135 and 3,534,687 - is disadvantageous in that the distance between the four tamping tools mounted on the common unit frame cannot be varied to adapt to differently spaced tamping obstacles.

Außerdem ist durch die GB 2 201 178 A noch ein aus vier voneinander unabhängig querverschiebbaren Stopfeinheiten gebildetes Stopfaggregat bekannt, wobei allerdings die beiden jeweils einer Stopfeinheit zugeordneten Stopfpickel starr mit dem jeweiligen Stopfwerkzeug verbunden sind. Dadurch sind allerdings, wie die Darstellung in Fig. 4 sehr deutlich zeigt, noch immer große Bereiche einer Weiche nicht unterstopfbar.In addition, GB 2 201 178 A discloses a tamping unit formed from four tamping units which can be displaced independently of one another laterally, but the two tamping picks each associated with a tamping unit are rigidly connected to the respective tamping tool. As a result, as the illustration in FIG. 4 shows very clearly, large areas of a switch can still not be blocked.

Schließlich ist noch durch die AT-PS 378 386 ein weiteres Stopfaggregat mit zwei Stopfeinheiten bekannt, deren Aggregatrahmen jeweils - zum zeitlich aufeinanderfolgenden Eintauchen in den links bzw. rechts einer Schiene gelegenen Stopfbereich - um eine in Maschinenlängsrichtung verlaufende Achse verschwenkbar ausgebildet und mit einem Paar von Stopfwerkzeugen verbunden sind. Diesen sind jeweils zwei Stopfpickel zugeordnet, von denen einer um eine in Maschinenlängsrichtung verlaufende Schwenkachse drehbar gelagert ist. Damit ist dieser drehbare Stopfpickel von einer normalen, zum anderen Stopfpickel geringfügig distanzierten Stopfstellung in eine den anderen Stopfpickel überlappende Stellung verschwenkbar. In dieser die Eintauchbreite reduzierenden Stellung der Stopfpickel ist die Stopfeinheit auch in schmälere, z.B. durch Stamm- und Abzweiggleis begrenzte Stopfbereiche eintauchbar. Allerdings muß dann die Stopfeinheit bei der in Fig. 2 dargestellten Gleissituation zum Unterstopfen des an jeder Schienenlängsseite gelegenen Stopfbereiches insgesamt dreimal hintereinander zentriert, abgesenkt und wieder angehoben werden.Finally, from AT-PS 378 386 a further tamping unit with two tamping units is known, the unit frame of which is designed to be pivotable about an axis running in the longitudinal direction of the machine and with a pair of - for successive immersion in the tamping area located on the left or right of a rail Darning tools are connected. These are each assigned two tamping axes, one of which is rotatably mounted about a pivot axis running in the machine longitudinal direction. This rotatable tamping pick can thus be pivoted from a normal tamping position slightly distanced to the other tamping pick into a position overlapping the other tamping pick. In this position of the tamping pick, which reduces the plunge width, the tamping unit is also in narrower, e.g. Tamping areas delimited by trunk and branch track can be immersed. However, in the track situation shown in FIG. 2, the stuffing unit must then be centered, lowered and raised three times in a row to stuff the stuffing area located on each longitudinal side of the rail.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, ein Stopfaggregat der eingangs genannten Art zu schaffen, das sich bei relativ geringem konstruktivem Aufwand für eine vereinfachte Positionierung der Stopfpickel und weitestgehende Unterstopfung von Weichenabschnitten eignet.The present invention is based on the object of a tamping unit To create the type mentioned, which is suitable for a relatively low design effort for a simplified positioning of the tamping pick and extensive tamping of switch sections.

Diese Aufgabe wird erfindungsgemäß mit einem Stopfaggregat der eingangs beschriebenen Art dadurch gelöst, daß der an den Aggregatrahmen angrenzende Innen-Stopfpickel jeder Stopfeinheit starr mit dem Stopfwerkzeug verbunden ist, während der in Maschinenquerrichtung benachbarte Außen-Stopfpickel zwischen zwei durch Anschläge begrenzten Endstellungen von einer an den Innen-Stopfpickel unmittelbar anschließenden ersten Stopfposition in eine - zum Eintauchen der beiden Stopfpickel beidseits einer Schiene geeignete - zweite Stopfposition um die Schwenkachse verschwenkbar ist. Mit den beiden, zwei unterschiedliche Stopfpositionen des Außen-Stopfpickels begrenzenden Anschlägen hat sich die Anmelderin erstmals von der bisher in der Fachwelt vorherrschenden Meinung gelöst, daß ein quer zur Maschinenlängsrichtung verschwenkbarer Stopfpickel in eine "Außerbetriebstellung" hochschwenkbar (bzw. wie im Falle der AT-PS 378 386 in eine "Außerbetriebstellung" einschwenkbar) sein muß, um damit auch im Falle eines unter diesem hochgeschwenkten Stopfpickel befindlichen Stopfhindernisses wenigstens die restlichen Stopfpickel zur Unterstopfung absenken zu können. Das erfindungsgemäße Merkmal zweier Stopfpositionen kommt jedoch erst in Verbindung mit einem zweiten, starr befestigten Stopfpickel sowie der Anordnung von insgesamt vier unabhängig voneinander querverschiebbaren Stopfeinheiten besonders wirkungsvoll zur Geltung. Erst dadurch besteht die Möglichkeit, die vier Stopfwerkzeugpaare unabhängig voneinander in einer ersten Zentrierstufe optimal über den jeweiligen Stopfauflagern zu zentrieren, um schließlich in einer zweiten darauffolgenden Zentrierstufe - je nach der im Bereich jedes einzelnen Stopfwerkzeuges vorliegenden Situation von Stopfhindernissen - zwischen der ersten oder zweiten Stopfposition der Stopfpickel zu wählen.This object is achieved with a tamping unit of the type described in the introduction in that the inner tamping pick adjacent to the unit frame of each tamping unit is rigidly connected to the tamping tool, while the outer tamping pick adjacent in the cross-machine direction between two end positions limited by stops from one to the Inner tamping pimple immediately following the first tamping position into a second tamping position, which is suitable for immersing the two tamping picks on both sides of a rail, can be pivoted about the pivot axis. With the two stops, which limit two different tamping positions of the external tamping pick, the applicant has for the first time freed itself from the prevailing opinion in the professional world that a tamping pick which can be pivoted transversely to the machine longitudinal direction can be swiveled up into an "out-of-operation position" (or as in the case of the AT- PS 378 386 must be pivoted into an "out-of-operation position") in order to be able to lower at least the remaining tamping picks for tamping even in the event of a tamping obstacle located under this tipped pick-up. However, the feature according to the invention of two tamping positions is particularly effective only in connection with a second, rigidly attached tamping pick and the arrangement of a total of four tamping units which can be displaced independently of one another. This is the only way to optimally center the four pairs of tamping tools independently of one another in a first centering stage above the respective tamping supports, and finally in a second subsequent centering stage - depending on the situation of tamping obstacles in the area of each individual tamping tool - between the first or second tamping position to choose the darning.

Durch die erfindungsgemäße Kombination sind die Stopfwerkzeuge erstmals über sämtliche möglichen Stopfauflager eines Weichenabschnittes für dessen vollständige Unterstopfung zentrierbar. Dabei ist von ganz besonderem Vorteil, daß durch die Begrenzung auf lediglich zwei mögliche Stopfpositionen des Außen-Stopfpickels der Steuerungsaufwand für die richtige Positionierung des verschwenkbaren Stopfpickels auf ein Minimum reduziert ist. Dies erleichtert die Stopfarbeit unter beträchtlicher Einschränkung des dafür erforderlichen Konzentrationsaufwandes durch die Bedienungsperson ganz wesentlich, da nunmehr nicht länger - wie bei bekannten Lösungen - zwischen unendlich vielen Stellungen der zahlreichen verschwenkbaren Stopfpickel, sondern lediglich zwischen zwei Endstellungen entschieden werden muß; und auch diese Entscheidung ist nur an jenen Stellen des Gleises erforderlich, in denen infolge eines noch sehr kleinen Winkels zwischen Haupt- und Abzweiggleis lediglich ein einziger Stopfpickel eintauchbar ist. Dieser wesentlich reduzierte Konzentrationsaufwand für die Bedienungsperson ist vor allem unter dem Gesichtspunkt zu sehen, daß bei bekannten Lösungen die Position von bis zu 16 Stopfpickeln für jeden einzelnen Stopfzyklus eingestellt und überwacht werden muß.With the combination according to the invention, the tamping tools can be centered for the first time over all possible tamping supports of a switch section for its complete tamping. It is of particular advantage that the control effort for the correct positioning of the pivotable tamping pick is reduced to a minimum by the limitation to only two possible tamping positions of the external tamping pick. This considerably simplifies the tamping work, with considerable restriction of the concentration effort required for this by the operator, since it is no longer - as with known ones Solutions - between an infinite number of positions of the numerous swiveling tamping axes, but only a decision must be made between two end positions; and this decision is only necessary at those points on the track where, due to a very small angle between the main and branch track, only a single tamping pimple can be immersed. This significantly reduced concentration effort for the operator can be seen above all from the point of view that the position of up to 16 tamping picks must be set and monitored for each individual tamping cycle in known solutions.

Ein weiterer wesentlicher Vorteil der erfindungsgemäßen Lösung besteht auch noch darin, daß im Falle der zweiten Stopfposition des Außen-Stopfpickels beide Stopfauflager der zwischen Außen- und Innen-Stopfpickel gelegenen Schiene in besonders rationeller Weise gleichzeitig mit nur einem einzigen Zentriervorgang der Stopfeinheit sowie mit lediglich einem einzigen Absenkvorgang der Stopfwerkzeuge verdichtbar sind. Diese Vereinfachung des Arbeitsablaufes führt zu einer wesentlich rascheren und effizienteren Unterstopfung von Weichenabschnitten, zumal in diesen Gleisbereichen infolge von zahlreichen "Stopfhindernissen", wie Herzstücken, Hilfsschienen, Schleuderschutz, Weichenzungen und dgl., praktisch für jeden Stopfzyklus eine andere Positionierung der Stopfeinheiten und bzw. oder der Stopfpickel erforderlich ist.Another significant advantage of the solution according to the invention is that, in the case of the second tamping position of the external tamping pick, both tamping supports of the rail located between the external and internal tamping pick are particularly efficient at the same time with only a single centering operation of the tamping unit and with only one single lowering process of the tamping tools can be compacted. This simplification of the workflow leads to a considerably faster and more efficient tamping of switch sections, especially in these track areas due to numerous "stuffing obstacles", such as heart pieces, auxiliary rails, anti-skid devices, switch tongues and the like, practically a different positioning of the stuffing units for each stuffing cycle and / or or the darning pimple is required.

Durch die Ausgestaltung nach den Ansprüchen 2, 3 oder 4 ist - in Maschinenlängsrichtung gesehen - bei seitlicher Anordnung der Stopfwerkzeuge am Aggregatrahmen eine problemlose Verdichtung der beidseits einer Schiene gelegenen Stopfauflager durch zwei unmittelbar aneinandergrenzende Stopfeinheiten möglich. Außerdem wird damit eine zu starke Abwinkelung des Außen-Stopfpickels in dessen zweiter Stopfposition vermieden, so daß auch in dieser die Höhenlage der Pickelplatten der beiden voneinander distanzierten Stopfpickel in bezug auf die Schwellenunterkante gleich ist.Due to the design according to claims 2, 3 or 4 - seen in the machine longitudinal direction - with a lateral arrangement of the tamping tools on the unit frame, a problem-free compression of the tamping supports located on both sides of a rail by two immediately adjacent tamping units is possible. In addition, an excessive bending of the outer tamping pick in its second tamping position is avoided, so that the height of the pimple plates of the two spaced tamping picks, in relation to the lower edge of the sleeper, is also the same in this position.

Die Ausgestaltung nach den Ansprüchen 5 und 6 ermöglicht eine besonders stabile und konstruktiv einfache Ausbildung der Anschläge in Verbindung mit einer sehr kurzen Ausbildung des Verschwenkantriebes.The design according to claims 5 and 6 enables a particularly stable and structurally simple design of the stops in conjunction with a very short design of the swivel drive.

Im folgenden wird die Erfindung an Hand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben.The invention is described in more detail below with reference to an embodiment shown in the drawing.

Das in Fig. 1 und 2 ersichtliche Stopfaggregat 1 setzt sich aus insgesamt vier in Maschinenquerrichtung nebeneinander angeordneten und durch Antriebe 2 unabhängig voneinander querverschiebbaren Stopfeinheiten 3 zusammen, von denen - wie bereits erwähnt - der besseren Übersicht wegen lediglich zwei jeweils einer Schienenlängsseite einer Schiene 4 zugeordnete Einheiten dargestellt sind. Jede der insgesamt vier Stopfeinheiten 3 weist einen vertikalen Aggregatrahmen 5 mit Vertikalführungen 6 auf. Auf diesen ist ein Werkzeugträger 7 mit Hilfe eines Antriebes 8 höhenverstellbar gelagert. Auf dem Werkzeugträger 7 ist ein Paar von in Maschinenlängsrichtung voneinander distanzierten Stopfwerkzeugen 9 befestigt, wobei die Stopfwerkzeuge 9 jeweils mit Hilfe eines Beistell- und Vibrationsantriebes 10,11 um eine senkrecht zur Maschinenlängsrichtung verlaufende Horizontalachse 12 beistell- und vibrierbar sind.The tamping unit 1 shown in FIGS. 1 and 2 is composed of a total of four tamping units 3 arranged next to one another in the cross-machine direction and which can be moved independently of one another by drives 2, of which - as already mentioned - for better clarity, only two are assigned to a rail 4 on each longitudinal side of the rail Units are shown. Each of the four tamping units 3 has a vertical unit frame 5 with vertical guides 6. A tool carrier 7 is mounted on these in a height-adjustable manner by means of a drive 8. A pair of tamping tools 9, which are spaced apart from one another in the longitudinal direction of the machine, are fastened on the tool carrier 7, the tamping tools 9 being able to be provided and vibrated with the aid of an auxiliary and vibration drive 10, 11 about a horizontal axis 12 running perpendicular to the longitudinal direction of the machine.

Jedes Stopfwerkzeug 9 ist in seinem unteren Endbereich mit zwei in Maschinenquerrichtung nebeneinander angeordneten Stopfpickeln 13, 14 verbunden. Von diesen ist der in Bezug auf den Aggregatrahmen 5 näher gelegene Innen-Stopfpickel 14 jeweils starr mit dem Stopfwerkzeug 9 verbunden, während der gegenüberliegende Außen-Stopfpickel 13 um eine in Maschinenlängsrichtung verlaufende Schwenkachse 15 verschwenkbar am Stopfwerkzeug 9 gelagert ist. Dabei ist die Verschwenkbewegung des Außen-Stopfpickels 13 durch einerseits am Innen- und andererseits am Außen-Stopfpickel 14 bzw. 13 angeordnete Anschläge 16, 17,24,25 begrenzt. In einem diesen Anschlägen 16, 17,24,25 in Maschinenquerrichtung gegenüberliegenden Bereich ist der Außen-Stopfpickel 13 mit einem Verschwenkantrieb 18 gelenkig verbunden, der mit seinem oberen Ende am Stopfwerkzeug 9 befestigt ist. Längsachsen 20,21 der beiden Stopfpickel 13,14 schließen jeweils mit einer Vertikalebene 22 einen Winkel α bzw. β von etwa 7° ein. Dieser Winkel kann aber auch vorzugsweise von etwa 5 bis etwa 10° gewählt werden. Mit 19 ist ein die Schwenkachse 15 aufweisendes Schwenklager bezeichnet. Die Längsachse 20 des Innen-Stopfpickels 14 jeder Stopfeinheit ist von oben nach unten in Richtung zum Aggregatrahmen 5 geneigt angeordnet, während die Längsachse 21 des benachbarten Außen-Stopfpickels 13 in einer ersten Stopfposition parallel zum Innen-Stopfpickel 14 verlaufend ausgebildet ist (siehe rechte Stopfeinheit 3 in Fig. 1).Each tamping tool 9 is connected in its lower end region to two tamping picks 13, 14 arranged side by side in the cross-machine direction. Of these, the inner tamping pick 14, which is closer in relation to the assembly frame 5, is rigidly connected to the tamping tool 9, while the opposite outer tamping pick 13 is pivotably mounted on the tamping tool 9 about a pivot axis 15 running in the machine longitudinal direction. Here is the Pivotal movement of the outer tamping pick 13 is limited by stops 16, 17, 24, 25 arranged on the one hand on the inner and on the other hand on the outer tamping pick 14 or 13. In a region opposite these stops 16, 17, 24, 25 in the cross-machine direction, the outer tamping pick 13 is connected in an articulated manner to a pivoting drive 18 which is attached to the tamping tool 9 with its upper end. Longitudinal axes 20, 21 of the two tamping axes 13, 14 each enclose an angle α or β of approximately 7 ° with a vertical plane 22. However, this angle can also preferably be selected from approximately 5 to approximately 10 °. With 19 a pivot bearing 15 having pivot bearing is designated. The longitudinal axis 20 of the inner tamping pick 14 of each tamping unit is arranged inclined from top to bottom in the direction of the unit frame 5, while the longitudinal axis 21 of the adjacent outer tamping pick 13 is designed to run parallel to the inner tamping pick 14 in a first tamping position (see right tamping unit) 3 in Fig. 1).

Mit Hilfe des Verschwenkantriebes 18 ist jeder Außen-Stopfpickel 13 von einer durch die Anschläge 16 und 17 begrenzten Endstellung bzw. ersten Stopfposition 23 in eine weitere, durch die Anschläge 24 und 25 begrenzte Endstellung bzw. zweite Stopfposition 26 verschwenkbar. In der ersten Stopfposition 23 bildet der Außen-Stopfpickel 13 gemeinsam mit dem Innen-Stopfpickel 14 ein Stopfpickel-Paar zum gemeinsamen Verdichten eines links bzw. rechts der Schiene gelegenen Stopfauflagers 27. In der zweiten Stopfposition 26 sind die beiden Stopfpickel 13,14 derart weit voneinander distanziert, daß beim Absenken des Stopfwerkzeuges 9 gleichzeitig zwei jeweils im Bereich einer Schienenlängsseite befindliche Stopfauflager 27 verdichtbar sind.With the aid of the pivoting drive 18, each outer tamping pick 13 can be pivoted from an end position or first tamping position 23 delimited by the stops 16 and 17 into a further end position or second tamping position 26 delimited by the stops 24 and 25. In the first tamping position 23, the outer tamping pick 13 together with the inner tamping pick 14 forms a pair of tamping tacks for jointly compacting a tamping support 27 located on the left or right of the rail. In the second tamping position 26, the two tamping pick 13, 14 are so wide spaced apart from one another so that when the tamping tool 9 is lowered, two tamping supports 27, each located in the region of a longitudinal side of the rail, can be compressed.

Jeder Aggregatrahmen 5 ist in seinem oberen Endbereich mit Führungsbuchsen 28 verbunden, die ihrerseits auf mit einem Maschinenrahmen 29 einer Gleisstopfmaschine verbundenen Querführungen 30 querverschiebbar gelagert sind. Die Führungsbuchsen 28 der beiden mittig angeordneten Stopfeinheiten 3 weisen im Bereich des Aggregatrahmens 5 jeweils eine Erweiterung 31 auf. Durch diese kann der vom Aggregatrahmen 5 jeder außen liegenden Stopfeinheit 3 in Richtung zur Maschinenmitte vorragende Teil der Führungsbuchse 28 aufgenommen werden, so daß die beiden einer Maschinenhälfte zugeordneten Stopfeinheiten 3 problemlos in eine unmittelbar aneinandergrenzende Position verschiebbar sind, in der die beiden jeder Schienenlängsseite zugeordneten Stopfauflager 27 jeweils mit zwei Stopfpickeln 13, 14 verdichtbar sind.Each unit frame 5 is connected in its upper end region to guide bushes 28, which in turn are mounted on transverse guides 30 which are connected to a machine frame 29 of a track tamping machine and can be displaced transversely. The guide bushings 28 of the two centrally arranged tamping units 3 each have an extension 31 in the region of the unit frame 5. Through this, the part of the guide bushing 28 projecting from the unit frame 5 of each outer tamping unit 3 towards the center of the machine can be accommodated, so that the two tamping units 3 assigned to one machine half can be easily moved into an immediately adjacent position in which the two tamping supports assigned to each longitudinal side of the rail 27 are compressible with two tamping axes 13, 14.

In der in Fig. 3 ersichtlichen Weiche sind die in der ersten Stopfposition 23 stopfbaren Bereiche mit einer durchgehenden, fetten Linie dargestellt, während die in der zweiten Stopfposition 26 verdichtbaren Stopfauflager 27 mit einer strichlierten, fetten Linie dargestellt sind. Mit 32 sind die Schienen eines Hauptgleises und mit 33 die Schienen eines Abzweiggleises bezeichnet. Wie durch die fetten Linien klar ersichtlich, ist durch das Stopfaggregat 1 praktisch die gesamte Weiche, insbesondere in den schwierigen, zahlreiche Stopfhindernisse aufweisenden Abschnitten, unterstopfbar. Der nicht unterstopfbare äußere Teil des Abzweiggleises kann problemlos im Zuge der Unterstopfung des gesamten Abzweiggleises bearbeitet werden.3, the areas that can be stuffed in the first stuffing position 23 are shown with a solid, bold line, while the stuffing pads 27 that can be compacted in the second stuffing position 26 are shown with a dashed, bold line. With 32 the rails of a main track and with 33 the rails of a branch track are designated. As can be clearly seen from the bold lines, the tamping unit 1 can be used to tamp practically the entire switch, particularly in the difficult sections which have numerous tamping obstacles. The outer part of the branch track, which cannot be tamped, can be easily processed by tamping the entire branch track.

Die für den Querschnitt IV-IV in Fig. 3 erforderliche Position der vier Stopfeinheiten 3 sowie der Stopfpickel 13, 14 ist in Fig. 4 dargestellt. Dabei ist deutlich ersichtlich, daß bei der - von links nach rechts gesehen - ersten und dritten Stopfeinheit 3 die Stopfpickel 13, 14 in der ersten Stopfposition 23 parallel zueinander ausgerichtet sind, während sich bei der zweiten und vierten Stopfeinheit 3 die Außen-Stopfpickel 13 in der zweiten Stopfposition 26 befinden. Dazu werden (siehe auch Fig. 1) vorerst die vier Antriebe 2 beaufschlagt, bis in einer ersten Zentrierstufe die jeweilige Stopfeinheit 3 über dem zu verdichtenden Stopfauflager 27 bzw. über einer Schiene 33 eines Abzweiggleises zentriert ist. In einer zweiten Zentrierstufe, die auch parallel zur ersten Stufe durchführbar ist, wird anschließend bei der zweiten und vierten Stopfeinheit 3 der Verschwenkantrieb 18 beaufschlagt, so daß der jeweilige Außen-Stopfpickel 13 in die zweite Stopfposition 26 verschwenkt wird. Mit dieser Stellung der vier Stopfeinheiten 3 zueinander bzw. der Position der einzelnen Stopfpickel 13,14 besteht die Möglichkeit, im Rahmen eines einzigen Absenkvorganges unter Beaufschlagung der Antriebe 8 insgesamt sechs in Maschinenquerrichtung nebeneinander und unterhalb der Schwelle 34 liegende Stopfauflager 27 zu verdichten. Dabei werden die an jeder Schienenlängsseite befindlichen Stopfauflager 27 der Schiene 33 des Abzweiggleises jeweils durch eine einzige Stopfeinheit 3 verdichtet.The position of the four tamping units 3 and the tamping pick 13, 14 required for the cross section IV-IV in FIG. 3 is shown in FIG. 4. It can be clearly seen that in the first and third tamping unit 3, as seen from left to right, the tamping pick 13, 14 are aligned parallel to one another in the first tamping position 23, while in the second and fourth tamping unit 3 the external tamping pick 13 is in the second stopper position 26. For this purpose (see also FIG. 1), the four drives 2 are initially acted on until the respective tamping unit 3 is centered in a first centering stage over the tamping support 27 to be compressed or over a rail 33 of a branch track. In a second centering stage, which can also be carried out parallel to the first stage, the pivoting drive 18 is then applied to the second and fourth tamping unit 3, so that the respective external tamping pick 13 is pivoted into the second tamping position 26. With this position of the four tamping units 3 relative to one another or the position of the individual tamping pick 13,14, it is possible to compress a total of six tamping supports 27 lying next to one another and below the threshold 34 in the course of a single lowering operation while acting on the drives 8. The tamping supports 27 of the rail 33 of the branch track located on each longitudinal side of the rail are each compressed by a single tamping unit 3.

Gemäß oberem, eine Schwelle 34 und die Stopfpickel 13,14 im Querschnitt V-V darstellenden Abschnitt der Fig. 5 sind in einem ersten Stopfzyklus sämtliche Stopfeinheiten 3 über den beiden Schienen 32 des Hauptgleises zentriert, wobei sich die Stopfpickel 13 jeweils in der ersten Stopfposition 23 befinden. Nach Beendigung des ersten Stopfzyklus wird lediglich die zweite und vierte Stopfeinheit 3 (von links gesehen) unter Beaufschlagung der Antriebe 2 so lange querverschoben, bis sie sich über den Schienen 33 des Abzweiggleises befinden. Anschließend bzw. parallel dazu werden die Außen-Stopfpickel 13 unter Beaufschlagung der Verschwenkantriebe 18 in die zweite Stopfposition 26 verschwenkt, so daß nach dem Absenken der Stopfwerkzeuge 9 der zweiten und vierten Stopfeinheit 3 die beiden jeweils beidseits der Schienen 33 des Abzweiggleises befindlichen Stopfauflager 27 verdichtbar sind.5, in a first tamping cycle, all tamping units 3 are centered over the two rails 32 of the main track, the tamping tines 13 each being in the first tamping position 23 . After the end of the first tamping cycle, only the second and fourth tamping unit 3 (seen from the left) are moved laterally until the drives 2 are acted on until they are located above the rails 33 of the branch track. Subsequently or in parallel, the outer tamping picks 13 are subjected to the pivoting drives 18 pivoted into the second tamping position 26, so that after the tamping tools 9 of the second and fourth tamping unit 3 have been lowered, the two tamping supports 27 located on either side of the rails 33 of the branch track can be compressed.

Bei der im Querschnitt VI-VI zutreffenden und in Fig. 6 ersichtlichen Position ist die erste und zweite Stopfeinheit 3 über der Schiene 32 des Hauptgleises zentriert, wobei sich die beiden Außen-Stopfpickel 13 jeweils in der ersten Stopfposition 23 befinden. Diese Stellung entspricht der normalen Stopfposition für jene Bereiche des Gleises, in denen keinerlei Stopfhindernisse vorhanden sind. Die Stopfpickel 13 der dritten Stopfeinheit 3 befinden sich in der zweiten Stopfposition 26 zur gleichzeitigen Unterstopfung der an jeder Längsseite der Schiene 33 des Abzweiggleises befindlichen Stopfauflager 27. Die Stopfpickel 13 der vierten Stopfeinheit 3 befinden sich in der ersten Stopfposition 23 zur Verdichtung des äußeren Stopfauflagers 27 der Schiene 32 des Hauptgleises. Nach dem Stopfvorgang besteht noch die Möglichkeit, mit Hilfe der vierten Stopfeinheit 3 unter entsprechender weiterer Querverschiebung (siehe strichpunktierte Linien) auch noch das innere Stopfauflager 27 der zweiten Schiene 33 des Abzweiggleises zu verdichten. Das im Rahmen dieses Arbeitsganges nicht verdichtbare äußerste Stopfauflager 27 kann problemlos bei der Durcharbeitung des Abzweiggleises bearbeitet werden.6, the first and second tamping units 3 are centered above the rail 32 of the main track, the two outer tamping pick 13 each being in the first tamping position 23. This position corresponds to the normal tamping position for those areas of the track in which there are no obstacles. The tamping tines 13 of the third tamping unit 3 are in the second tamping position 26 for simultaneous tamping of the tamping supports 27 located on each long side of the rail 33 of the branch track. The tamping tines 13 of the fourth tamping unit 3 are in the first tamping position 23 for compressing the outer tamping support 27 the rail 32 of the main track. After the tamping process, there is still the possibility of compressing the inner tamping support 27 of the second rail 33 of the branch track by means of the fourth tamping unit 3 with a corresponding further transverse displacement (see dash-dotted lines). The outermost tamping support 27, which cannot be compacted in the course of this operation, can be processed without problems when working through the branch track.
