Description

Die Erfindung betrifft eine fahrbare Gleisstopfmaschine mit insgesamt vier, jeweils einer Schienenlängsseite zugeordneten und in Gleisquerrichtung verstellbaren Stopfeinheiten, die jeweils mindestens zwei mittels Antrieben beistellbare und in Vibration versetzbare Stopfwerkzeuge aufweisen, welche an einem über Führungen höhenverstellbar mit einem Werkzeugrahmen verbundenen Werkzeugträger angeordnet sind.The invention relates to a mobile tamping machine with a total of four tamping units, each assigned to a longitudinal side of the rail and adjustable in the transverse direction of the track, each having at least two tamping tools that can be provided by means of drives and set in vibration, which are arranged on a tool holder that is height-adjustable and connected to a tool frame.

Es ist - gemäß DE-PS 3o 26 883 - bereits eine fahrbare Gleisstopfmaschine mit insgesamt vier, jeweils auf beiden Seiten einer Schiene angeordneten Stopfeinheiten bekannt, die unabhängig voneinander quer zur Gleislängsrichtung mittels eigener Antriebe bewegbar sind. Jede Stopfeinheit weist beistellbare Stopfwerkzeuge der herkömmlichen Art auf, welche mit einem Werkzeugträger verbunden und mitsamt diesem zum Eintauchen in den Schotter höhenverstellbar auf einem Werkzeugrahmen angeordnet sind. Um die Bewegbarkeit der Stopfeinheiten in Gleisquerrichtung zu ermöglichen, sind die jeweiligen Werkzeugrahmen über eine aus Querführungen und Hebeln bzw. Koppelstangen bestehende Vorrichtung mit dem Maschinenrahmen der Stopfmaschine verbunden. Die Beaufschlagung des Querverschiebeantriebes einer Stopfeinheit hat eine Kombination von Bewegungen der Stopfeinheit zur Folge, und zwar wird zusätzlich zur horizontalen Verstellung in Gleisquerrichtung auch eine Verschwenkbewegung des Werkzeugrahmens in einer quer zum Gleis verlaufenden Vertikalebene bewirkt. Das untere, die Stopfwerkzeuge aufweisende Ende des Werkzeugrahmens legt einen bogenförmigen und längeren Querverschiebeweg zurück als das obere Ende, welches mit den Koppelstangen verbunden ist und entlang der Querführung geradlinig verschoben wird. Mit einer derartigen Maschine können auch die längeren Schwellen in Weichen- und Kreuzungsbereichen unterstopft werden, wobei jedoch ein relativ großer konstruktiver Aufwand erforderlich ist.According to DE-PS 3o 26 883, a mobile track tamping machine with a total of four tamping units, each arranged on both sides of a rail, is known which can be moved independently of one another transversely to the longitudinal direction of the track by means of its own drives. Each tamping unit has tamping tools of the conventional type, which are connected to a tool carrier and, together with this, are arranged on a tool frame so as to be height-adjustable for immersion in the ballast. In order to enable the tamping units to move in the transverse direction of the track, the respective tool frames are connected to the machine frame of the tamping machine via a device consisting of transverse guides and levers or coupling rods. The action of the transverse displacement drive of a tamping unit results in a combination of movements of the tamping unit, and in addition to the horizontal adjustment in the transverse direction of the track, a pivoting movement of the tool frame is also effected in a vertical plane running transverse to the track. The lower end of the tool frame, which has the tamping tools, travels an arcuate and longer transverse displacement path than the upper end, which is connected to the coupling rods and is moved in a straight line along the transverse guide. Such a machine can also be used to support the longer sleepers in points and crossings, but this requires a relatively large amount of construction.

Weiters ist - gemäß AT-PS 379 625 - auch eine Maschine zum Unterstopfen der Schwellen eines Gleises bekannt, bei der zwei jeweils einer Schiene zugeordnete Stopfaggregate unabhängig voneinander auf Querführungen verschiebbar an einem Maschinenrahmen angeordnet sind. Jedes Stopfaggregat weist einen Werkzeugrahmen mit vertikalen Führungssäulen auf, an denen zwei voneinander unabhängig höhenverstellbare, herkömmliche Stopfwerkzeug-Paare aufweisende Werkzeugträger gelagert sind. Bei Auftreten eines Gleishindernisses, z.B. einer Weichenzunge etc., wird das über diesem Hindernis befindliche Stopfwerkzeug-Paar nicht abgesenkt, während das gegenüberliegende Stopfwerkzeug-Paar ungehindert zur Unterstopfung einsetzbar ist. Der Querverstellbereich der Stopfwerkzeuge ist jedoch durch die Anordnung der Querführungen innerhalb des Maschinenprofils begrenzt.Furthermore, according to AT-PS 379 625, a machine for stuffing the sleepers of a track is known, in which two tamping units, each assigned to a rail, are arranged on a machine frame so as to be displaceable independently of one another on transverse guides. Each tamping unit has a tool frame with vertical guide columns, on which two tool carriers, which are independently height-adjustable and have conventional tamping tool pairs, are mounted. If a track obstacle occurs, e.g. a switch tongue etc., the tamping tool pair located above this obstacle is not lowered, while the opposite tamping tool pair can be used unimpeded for tamping. The transverse adjustment range of the tamping tools is limited by the arrangement of the transverse guides within the machine profile.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine Gleisstopfmaschine für Weichen- und Kreuzungsbereiche zu schaffen, mit welcher unter lediglich geringem konstruktivem Mehraufwand eine möglichst weitgehende Querverschiebung der Stopfwerkzeuge möglich ist.The object of the present invention is to create a track tamping machine for switch and crossing areas, with which the greatest possible transverse displacement of the tamping tools is possible with only little additional construction effort.

Diese Aufgabe wird mit einer Maschine der gattungsgemässen Art dadurch gelöst, daß der Werkzeugrahmen jeder in bezug auf die Gleis- bzw. Maschinenquerrichtung äußeren Stopfeinheit am Werkzeugrahmen der benachbarten, in Maschinenquerrichtung inneren Stopfeinheit gelagert und von dieser mittels eines Verstellantriebes in Gleisquerrichtung distanzierbar ist und daß die beiden inneren Stopfeinheiten auf quer zur Maschinenlängsrichtung verlaufenden Querführungen unabhängig voneinander verschiebbar gelagert sind. Da die äußere Stopfeinheit auf der benachbarten inneren Stopfeinheit verstellbar befestigt ist, kann letztere in einem Maximalbereich entlang der Querführung innerhalb des Maschinenprofils seitlich nach außen querverschoben und diese Querverschiebung noch durch eine zusätzliche Distanzierung der äußeren Stopfeinheit verlängert werden. Damit ist mit relativ geringem konstruktivem Mehraufwand sowie unter Beibehaltung bestens bewährter Baugruppen die Möglichkeit geschaffen, wahlweise die Schiene unter Kupplung beider Stopfeinheiten miteinander wie ein normales Strecken-Stopfaggregat bei gleichbleibender Distanzierung der beiden Stopfwerkzeug-Paare zueinander zu unterstopfen oder unter Beaufschlagung des Verstellantriebes beide Stopfeinheiten dem unregelmäßigen Schienenverlauf entsprechend zueinander zu distanzieren.This object is achieved with a machine of the generic type in that the tool frame each with respect to the track or machine cross direction outer tamping unit is mounted on the tool frame of the adjacent tamping unit inner in the cross machine direction and can be distanced therefrom by means of an adjustment drive in the cross track direction and that both inner Stuffing units are slidably mounted on transverse guides running transversely to the machine longitudinal direction. Since the outer tamping unit is adjustably attached to the adjacent inner tamping unit, the latter can be laterally displaced outwards in a maximum area along the transverse guide within the machine profile, and this transverse displacement can be lengthened by additional spacing of the outer tamping unit. This means that with relatively little additional design effort and while maintaining well-proven assemblies, the possibility is created to either stuff the rail by coupling both tamping units with one another like a normal stretch tamping unit with constant spacing of the two tamping tool pairs to one another, or to subject both tamping units to the adjustment drive to distance the irregular course of the rails accordingly.

Eine zweckmäßige Weiterbildung der Erfindung besteht darin, daß jede der äußeren Stopfeinheiten um eine oberhalb derselben in Maschinenlängsrichtung verlaufende Schwenkachse verschwenkbar am Werkzeugrahmen der benachbarten inneren Stopfeinheit angeordnet ist. Diese Lösung bietet eine einfache und robuste Konstruktion, die bestens geeignet ist, den im Arbeitseinsatz auftretenden stoßartigen Kräften standzuhalten.An expedient development of the invention consists in that each of the outer tamping units is arranged on the tool frame of the adjacent inner tamping unit so as to be pivotable about a pivot axis extending above it in the machine longitudinal direction. This solution offers a simple and robust construction that is ideally suited to withstand the shock-like forces that occur during work.

Ist die Schwenkachse durch quer zur Maschinenlängsrichtung verlaufende Flanschverbindungen von beiden Werkzeugrahmen distanziert im Bereich oberhalb der äußeren Stopfeinheit angeordnet, so wird trotz größerer Ausschwenk-Reichweite der Abstand der Stopfpickel von der Schwellenoberfläche bzw. Schotteroberfläche kaum vergrößert, so daß keine Korrektur der Eindringtiefe der Stopfpickel - auf Grund deren weitgehend linearer und horizontaler Querverschiebung - erforderlich ist.If the swivel axis is arranged at a distance from the two tool frames in the area above the outer tamping unit due to flange connections running transversely to the machine longitudinal direction, the distance of the tamping ax from the sleeper surface or ballast surface is hardly increased, despite the greater swiveling range, so that no correction is made to the penetration depth of the tamping ax - because of that largely linear and horizontal transverse displacement - is required.

Nach einem anderen Merkmal der Erfindung sind zwei in Maschinenlängsrichtung voneinander distanzierte, etwa auf halber Höhe der beiden Werkzeugrahmen angeordnete und diese miteinander verbindende Verstellantriebe vorgesehen. Durch diese Anordnung können die Verstellantriebe relativ kurz ausgebildet sein und bewirken dennoch eine sichere und verwindungsfeste Verschwenkung des äußeren Werkzeugrahmens.According to another feature of the invention, two adjustment drives are provided which are spaced apart from one another in the longitudinal direction of the machine and are arranged approximately at half the height of the two tool frames and connect them to one another. With this arrangement, the adjustment drives can be made relatively short and still bring about a secure and torsion-resistant pivoting of the outer tool frame.

Weiters ist nach einem anderen Ausführungsbeispiel zweckmäßigerweise jede äußere Stopfeinheit auf dem Werkzeugrahmen der benachbarten inneren Stopfeinheit querverschiebbar gelagert. Dadurch kann die Distanzierung der äußeren Stopfeinheiten von den inneren in Gleisquerrichtung unter Vermeidung einer Schrägstellung erfolgen, wodurch die Absenkbewegung der Stopfpickel in genau vertikaler Richtung gewahrt bleibt.Furthermore, according to another exemplary embodiment, each outer tamping unit is expediently displaceably mounted on the tool frame of the adjacent inner tamping unit. As a result, the outer tamping units can be distanced from the inner ones in the transverse direction of the track while avoiding an inclined position, as a result of which the lowering movement of the tamping pick is maintained in a precisely vertical direction.

Der Werkzeugrahmen jeder äußeren Stopfeinheit ist nach einem weiteren Ausführungsbeispiel der Erfindung auf mit dem Werkzeugrahmen der zugeordneten inneren Stopfeinheit verbundenen und in Maschinenquerrichtung parallel zu den Querführungen der inneren Stopfeinheiten verlaufenden Führungsholmen verschiebbar gelagert. Eine derartige Lagerung ermöglicht eine Querverstellung der äußeren Stopfeinheiten ohne irgendeine nachteilige Änderung der Eindringtiefe der Stopfpickel in den Schotter unter Beibehaltung des Vorteils der konstruktiven Einfach- und Robustheit.According to a further exemplary embodiment of the invention, the tool frame of each outer tamping unit is slidably mounted on guide rails connected to the tool frame of the associated inner tamping unit and extending in the cross-machine direction parallel to the transverse guides of the inner tamping units. Such a bearing enables the outer tamping units to be adjusted transversely without any disadvantageous change in the depth of penetration of the tamping pick into the ballast while maintaining the advantage of simple construction and robustness.

Eine in Fig.1 dargestellte Gleisstopfmaschine 1 weist einen langgestreckten Maschinenrahmen 2 auf, der über Fahrwerke 3 auf einem aus Schienen 4 und Schwellen 5 gebildeten Gleis 6 verfahrbar ist. Endseitig angeordnete Fahrkabinen 7 sowie eine Arbeitskabine 8 sind zur Aufnahme des Bedienungspersonals während der Überstellfahrt und der Arbeitsvorfahrt - in der durch einen Pfeil 9 angedeuteten Arbeitsrichtung - vorgesehen. Eine Energiequelle 1o dient zur Kraftversorgung sämtlicher Antriebe der Maschine 1 und deren Arbeitsaggregate, welche aus einem Gleishebe- und Richtaggregat 11 und diesem in Arbeitsrichtung nachgeordneten Weichen-Stopfaggregaten 12 bestehen. Die Arbeitsaggregate werden an Hand eines Nivellier- und Richtbezugsystems 13 während des Arbeitseinsatzes gesteuert.A track tamping machine 1 shown in FIG. 1 has an elongated machine frame 2 which can be moved via running gears 3 on a track 6 formed from rails 4 and sleepers 5. Driving cabins 7 arranged at the end and a working cabin 8 are provided for accommodating the operating personnel during the transfer journey and the right of way - in the working direction indicated by an arrow 9. An energy source 1o serves to supply power to all drives of machine 1 and their working units, which consist of a track lifting and straightening unit 11 and switch tamping units 12 arranged downstream thereof in the working direction. The work units are controlled by means of a leveling and straightening reference system 13 during work.

Aus Fig.2 ist der nähere Aufbau der Weichen-Stopfaggregate 12 ersichtlich, welche pro Schiene 4 jeweils eine in bezug auf die Gleis- bzw. Maschinenquerrichtung äußere Stopfeinheit 14 sowie eine innere Stopfeinheit 15 aufweisen, also aus insgesamt vier jeweils einer Schienenlängsseite zugeordneten Stopfeinheiten 14,15 bestehen. Jede äußere bzw. innere Stopfeinheit 14 bzw. 15 weist einen über vertikale Führungen 16 höhenverstellbar mit einem eigenen Werkzeugrahmen 17 bzw. 18 verbundenen und zwecks Absenkung von Stopfpickeln 19 in den Schotter mit Höhenverstellantrieben 2o ausgestatteten Werkzeugträger 21 auf. Die Höhenverstellantriebe 2o sind bei den inneren Stopfeinheiten 15 oberhalb des Werkzeugrahmens 18 angeordnet, während sie bei den äußeren Stopfeinheiten 14 - wie insbesondere aus Fig.3 zu ersehen ist - zum Großteil innerhalb des Werkzeugrahmens 17 vorgesehen sind.From Figure 2, the detailed structure of the switch tamping units 12 can be seen, each one per rail 4 with respect to the outer track or machine direction Have tamping unit 14 and an inner tamping unit 15, that is to say consist of a total of four tamping units 14, 15 each assigned to a rail longitudinal side. Each outer or inner tamping unit 14 or 15 has a tool holder 21 which is vertically adjustable with its own tool frame 17 or 18 and which is equipped with height adjustment drives 20 for the purpose of lowering tamping picks 19 in the ballast. The height adjustment drives 2o are arranged in the inner tamping units 15 above the tool frame 18, while in the outer tamping units 14 - as can be seen in particular from FIG. 3 - they are largely provided within the tool frame 17.

Die Werkzeugrahmen 18 der beiden inneren Stopfeinheiten 15 sind unabhängig voneinander auf quer zur Maschinenlängsrichtung verlaufenden und mit dem Maschinenrahmen 2 verbundenen Querführungen 22 gelagert und auf diesen mittels jeweils eines eigenen Querverschiebeantriebes 23 verschiebbar (siehe kleine Pfeile in Fig.2). Die Werkzeugrahmen 17 der äußeren Stopfeinheiten 14 sind jeweils an den Werkzeugrahmen 18 der ihnen benachbarten inneren Stopfeinheiten 15 gelagert und somit zusammen mit diesen in Gleisquerrichtung verschiebbar. Besagte Lagerung des äußeren auf dem inneren Werkzeugrahmen 17, 18 erfolgt in Form einer Flanschverbindung 24, mittels derer der äußere Werkzeugrahmen 17 um eine in Maschinenlängsrichtung verlaufende Schwenkachse 25 verschwenkbar bzw. vom zugeordneten inneren Werkzeugrahmen 18 distanzierbar ist. Hierzu dienen Verstellantriebe 26, welche im gezeigten Ausführungsbeispiel etwa auf halber Höhe der beiden Werkzeugrahmen 17,18 angeordnet sind und diese jeweils miteinander verbinden. Die Schwenkachse 25 ist weiters in Maschinenquerrichtung von den jeweiligen Werkzeugrahmen 17,18 distanziert bzw. im Bereich oberhalb der äußeren Stopfeinheiten 14 angeordnet. Dadurch wird erreicht, daß die Stopfpickel 19 nahezu linear und horizontal querverschoben werden. Beide Werkzeugrahmen 17,18 sind für den normalen Einsatz (siehe rechte Hälfte der Fig.2) durch eine entsprechende Verriegelungsvorrichtung wahlweise miteinander verbindbar. Die beiden inneren Stopfeinheiten 15 sind durch zwei in Maschinenlängsrichtung voneinander distanzierte Teleskopgestänge 40 miteinander verbunden. Diese sind in Maschinenquerrichtung längenveränderbar und durch Antriebe 41 in ihrer Verschiebbarkeit zueinander blockierbar.The tool frames 18 of the two inner tamping units 15 are mounted independently of one another on transverse guides 22 which run transversely to the machine longitudinal direction and are connected to the machine frame 2 and can be displaced thereon by means of their own transverse displacement drive 23 (see small arrows in FIG. 2). The tool frames 17 of the outer tamping units 14 are each mounted on the tool frames 18 of the inner tamping units 15 adjacent to them and can thus be displaced together with them in the transverse direction of the track. Said mounting of the outer on the inner tool frame 17, 18 takes place in the form of a flange connection 24, by means of which the outer tool frame 17 can be pivoted about a pivot axis 25 running in the machine longitudinal direction or can be distanced from the associated inner tool frame 18. Adjustment drives 26 are used for this purpose, which in the exemplary embodiment shown are arranged approximately at half the height of the two tool frames 17, 18 and each connect them to one another. The pivot axis 25 is further distanced in the cross-machine direction from the respective tool frame 17, 18 or in the area above the outer tamping units 14 arranged. It is thereby achieved that the tamping picks 19 are moved almost linearly and horizontally. Both tool frames 17, 18 can be connected to one another for normal use (see right half of FIG. 2) by means of a corresponding locking device. The two inner tamping units 15 are connected to one another by two telescopic rods 40 spaced apart in the machine longitudinal direction. These can be changed in length in the cross-machine direction and can be blocked relative to one another by drives 41.

Um die Arbeitsweise der erfindungsgemäßen Ausbildung zu illustrieren, sind in Fig.2 die beiden rechten Stopfeinheiten 14,15 - zum Stopfen der Schwelle 5 - in Normalstellung über einer Schiene 4 des Gleises 6 gezeigt, wobei kein Teil der äußeren Stopfeinheit 14 oder der Flanschverbindung 24 das Maschinenprofil 27 überschreitet. Die beiden linken Stopfeinheiten 14,15 werden - nach erfolgter Unterstopfung der anderen zum Hauptgleis gehörigen Schiene 4 - mittels des Querverschiebeantriebes 23 in die äußerste Querposition verschoben, um eine Schiene 28 eines Abzweiggleises zu unterstopfen. Um auch die - in bezug auf das Hauptgleis - außenliegende Seite der Schiene 28 mit den Stopfpickeln 19 zu erreichen, werden zusätzlich noch die beiden Verstellantriebe 26 beaufschlagt und dadurch die äußere Stopfeinheit 14 von der inneren Stopfeinheit 15 distanziert. Anschließend werden die Stopfpickel 19 der äußeren Stopfeinheit 14 mit Hilfe des Höhenverstellantriebes 20 zur Unterstopfung abgesenkt. Nach erfolgter Zentrierung der inneren Stopfeinheiten 15 werden diese unter Beaufschlagung der Antriebe 41 in ihrer Position zueinander stabilisiert.In order to illustrate the operation of the design according to the invention, the two right-hand tamping units 14, 15 - for tamping the threshold 5 - are shown in the normal position above a rail 4 of the track 6 in FIG. 2, with no part of the outer tamping unit 14 or the flange connection 24 the machine profile exceeds 27. The two left tamping units 14, 15 - after the other rail 4 belonging to the main track has been tamped - are moved into the outermost transverse position by means of the transverse sliding drive 23 in order to stuff a rail 28 of a branch track. In order to also reach the outer side of the rail 28 with the tamping picks 19 with respect to the main track, the two adjusting drives 26 are additionally acted upon and the outer tamping unit 14 is thereby spaced apart from the inner tamping unit 15. Then the tamping picks 19 of the outer tamping unit 14 are lowered with the aid of the height adjustment drive 20 for tamping. After the inner tamping units 15 have been centered, they are stabilized in their position relative to one another when the drives 41 are acted upon.

Unter entsprechender Beaufschlagung der Querverschiebeantriebe 23 und/oder der Verstellantriebe 26 ist es somit möglich, alle Stopfzonen einer Weichenschwelle bis zu einem relativ großen Seitenabstand zu dem von der Maschine 1 befahrenen Gleis 6 zu bearbeiten. Die als Doppel-Schwenkpickel ausgebildeten Stopfpickel 19 können zudem, je nach Erfordernis, einzeln seitlich ausgeschwenkt werden, um etwaigen Hindernissen beim Absenken auszuweichen. Sobald auf diese Weise nacheinander alle zu unterstopfenden Bereiche entlang einer Schwelle 5 im Weichenbereich bearbeitet wurden, wird die Maschine 1 zur nächsten Schwelle verfahren, wo sich die Arbeitsschritte wiederholen.When the transverse displacement drives 23 and / or the adjustment drives 26 are acted upon accordingly, it is thus possible to machine all tamping zones of a turnout threshold up to a relatively large lateral distance to the track 6 traveled by the machine 1. The tamping pick 19, which is designed as a double swivel pick, can, depending on requirements, also be individually pivoted out laterally in order to avoid any obstacles when lowering. As soon as all areas to be tamped have been processed in this way one after the other along a threshold 5 in the switch area, the machine 1 is moved to the next threshold, where the work steps are repeated.

In Fig.4 ist ein Werkzeugrahmen 29 einer inneren Stopfeinheit 30 dargestellt, der auf mit einem Maschinenrahmen 31 einer nicht näher dargestellten Gleisstopfmaschine 32 verbundenen Querführungen 33 mittels eines Verschiebeantriebes 34 in Maschinenquerrichtung verschiebbar gelagert ist. Mit dem Werkzeugrahmen 29 sind zwei Führungsholme 35 verbunden, die zu den Querführungen 33 parallel verlaufen und auf denen ein Werkzeugrahmen 36 einer äußeren Stopfeinheit 37 in Maschinenquerrichtung mittels eines Verstellantriebes 38 querverschiebbar gelagert ist. Die auf den Führungen 39 höhenverstellbaren Werkzeugträger und Stopfwerkzeuge sind hier nicht gezeigt. Die Arbeitsweise dieser Ausführungsform der Erfindung ist im wesentlichen gleich der bereits an Hand der Fig.2 beschriebenen. In einer geringfügigen Abwandlung dieser Ausführung ist es auch möglich, die Führungsholme 35 im Bereich ihrer äußeren Enden unverschiebbar am äußeren Werkzeugrahmen 36 zu befestigen und am inneren Werkzeugrahmen 29 querverschiebbar zu lagern. Die beiden Werkzeugrahmen 29 der inneren Stopfeinheiten 30 sind ebenfalls durch ein Teleskopgestänge 42 mit einem entsprechenden Antrieb zueinander blockierbar.4 shows a tool frame 29 of an inner tamping unit 30, which is mounted on transverse guides 33 connected to a machine frame 31 of a track tamping machine 32 (not shown in any more detail) by means of a displacement drive 34 in the transverse direction of the machine. With the tool frame 29, two guide rails 35 are connected, which run parallel to the transverse guides 33 and on which a tool frame 36 of an outer tamping unit 37 is mounted such that it can be displaced in the transverse direction of the machine by means of an adjustment drive 38. The height-adjustable tool carriers and tamping tools on the guides 39 are not shown here. The mode of operation of this embodiment of the invention is essentially the same as that already described with reference to FIG. In a slight modification of this embodiment, it is also possible to fasten the guide rails 35 immovably on the outer tool frame 36 in the region of their outer ends and to mount them transversely on the inner tool frame 29. The two tool frames 29 of the inner tamping units 30 can also be blocked relative to one another by a telescopic linkage 42 with a corresponding drive.
