Abstract

The machine (1) includes a track lifting unit (12) having an elevatable tool frame supported by lifting drives on a machine frame (5). Vertical adjustment drives control vertical position of lifting rollers relative to the tool frame. The operation of the vertical adjustment drives is interlocked with the operation of a transverse adjustment drive. Two pairs of lifting rollers are fixed to the tool frame, and are squeezed together by transverse adjustment drive transversely to the longitudinal direction. The track lifting unit and a working unit (6) are mounted on the machine frame. Flanged rollers support the tool frame to the rails of the track (3). The machine frame is supported with undercarriages (4) at movable state along the track.

Description

Die Erfindung betrifft eine Maschine zum Bearbeiten eines Gleises, mit einem auf Schienenfahrwerken abgestützten, ein Arbeitsaggregat und ein Gleishebeaggregat aufweisenden Maschinenrahmen, wobei das Gleishebeaggregat mit einem über Hebeantriebe höhenverstellbar mit dem Maschinenrahmen verbundenen Werkzeugrahmen ausgestattet ist, an dem pro Schiene des Gleises zwei in Schienenlängsrichtung voneinander distanzierte Paare von durch einen Querverstellantrieb in Gleisquerrichtung zueinander beistellbaren Heberollen sowie eine zum Abrollen auf einer Lauffläche der Schiene vorgesehene Spurkranzrolle angeordnet sind.The invention relates to a machine for processing a track, with a supported on rail chassis, a working unit and a Gleishebeaggregat having machine frame, wherein the track lifting unit with height adjustment via lifting drives with the machine frame equipped tool frame is attached to the each rail of the track two spaced apart in the rail longitudinal direction Pairs of by a Querverstellantrieb in transverse direction to each other settable lifting rollers and one for unrolling on a Tread of the rail provided flange are arranged.

Die zangenartig wirkenden Heberollenpaare stehen dabei formschlüssig mit dem Schienenkopf in Eingriff und rollen an dessen Unterseite ab, wodurch eine kontinuierliche Arbeitsvorfahrt der Maschine im Arbeitseinsatz möglich ist. Bei Auftreten von Hindernissen bzw. stark unregelmäßigen Schienenformen werden die beiden hintereinanderliegenden Paare von Heberollen nacheinander geöffnet und jeweils nach Passieren der Problemstelle wieder geschlossen, sodaß eine durchgehende Erfassung der Schiene durch wenigstens ein Rollenpaar ohne Unterbrechung gewährleistet bleibt.The pincer-acting lifting roller pairs are form-fitting engaged with the rail head and roll on the underside thereof, whereby a continuous working approach of the machine in the labor input is possible. In case of obstacles or strongly irregular Rail forms are the two consecutive pairs of Lifting rollers open one after the other and after passing the problem area closed again, so that a continuous recording of Rail guaranteed by at least one pair of rollers without interruption remains.

Bei einer in US 4,893,565 beschriebenen Stopfmaschine sind Greiforgane anhand eines Antriebes höhenverstellbar ausgebildet, wodurch die Möglichkeit geschaffen wird, die Greifhaken mit dem Schienenkopf oder wahlweise auch mit dem Schienenfuß in Eingriff zu bringen. In a tamping machine described in US 4,893,565 are gripping members designed height adjustable by means of a drive, creating the possibility is created, the gripping hooks with the rail head or optional also to engage with the rail foot.

Die Aufgabe der vorliegenden Erfindung besteht nun in der Schaffung einer gattungsgemäßen Maschine, mit der Änderungen des Querschnittes aufweisende Schienenabschnitte leichter und sicherer überwindbar sind.The object of the present invention is now to provide a generic machine, with the changes of the cross section rail sections easier and safer to overcome.

Diese Aufgabe wird erfindungsgemäß mit einer Maschine der eingangs genannten Art dadurch gelöst, daß jedes Paar von Heberollen in Bezug auf den Werkzeugrahmen anhand eines Höhenverstellantriebes unabhängig höhenverstellbar ausgebildet ist, und daß mit einer Distanzierung der beiden in Gleisquerrichtung nebeneinanderliegenden Heberollen voneinander eine automatische Beaufschlagung des Höhenverstellantriebes für ein Absenken beider Heberollen in Bezug auf den Werkzeugrahmen gekoppelt ist.This object is achieved with a machine of the initially mentioned type solved in that each pair of lifting rollers with respect independent on the tool frame by means of a height adjustment drive is designed adjustable in height, and that with a distancing the both adjacent track rollers in track transverse direction of each other an automatic loading of the height adjustment for a lowering of both lifting rollers coupled with respect to the tool frame is.

Ein derart ausgebildetes Gleishebeaggregat bietet den Vorteil, daß die zum Überfahren eines Schienenhindernisses bzw. bei einer Änderung des Schienenquerschnittes vorübergehend voneinander distanzierten Heberollen eines Paares nach dem Passieren dieser Stelle sicher und problemlos wieder geschlossen bzw. zueinander beigestellt werden können. Dies ist insbesondere im Falle einer größeren Anhebung des Gleisrostes von Bedeutung, da es hierbei beim Öffnen der durch die Heberollenpaare gebildeten Zange unweigerlich zu einem Absacken des Gleisrostes und damit zu einer Änderung der Schienenbiegelinie kommt. Diese vertikale Verlagerung des Gleises bzw. der zu erfassenden Schienen wird nun durch die automatische Absenkung der Heberollen auf einfache Art und in höchst zuverlässiger Weise kompensiert, sodaß sich die Heberollen sofort wieder in der richtigen Position in Bezug auf den Schienenkopf befinden. Da aufgrund des automatischen Ablaufes dieser Verstellbewegung die besondere Aufmerksamkeit der Bedienungsperson der Maschine hierfür nicht erforderlich ist, kann auch eine Ablenkung und dadurch eine etwaige Beeinträchtigung der Sicherheit beim Arbeitseinsatz vermieden werden. Such a trained lift elevator unit offers the advantage that the for driving over a rail obstacle or when changing the Rail cross section temporarily spaced lifting rollers a couple after passing this place safely and easily closed again or can be provided to each other. This is especially in the case of a major increase in the track since it is here when opening the formed by the lifting roller pairs Tongs inevitably to a sagging of the track grate and thus comes to a change in the rail bend line. This vertical displacement of the track or to be detected rails is now through the automatic lowering of the lifting rollers in a simple way and in the highest reliably compensated, so that the lifting rollers immediately in the correct position with respect to the rail head. Because due the automatic sequence of this adjustment the special Attention of the operator of the machine for this not required is, can also be a distraction and thus any impairment Safety at work to be avoided.

Die Weiterbildung nach Anspruch 2 sorgt in diesem Zusammenhang dafür, daß nach dem Beistellen der Paare von Heberollen der Gleisrost automatisch wieder in die vorher eingenommene Lage zurückgehoben wird, um einen reibungslosen Arbeitsfortschritt zu garantieren.The development according to claim 2 ensures in this context, that after the supply of the pairs of lifting rollers of the track grid automatically is lifted back into the previously taken position to to guarantee a smooth work progress.

Zusätzliche erfindungsgemäße Vorteile ergeben sich aus den weiteren Unteransprüchen und der Beschreibung.Additional advantages of the invention will become apparent from the other dependent claims and the description.

Die Erfindung wird im folgenden an Hand eines in den Zeichnungen dargestellten, bevorzugten Ausführungsbeispieles näher beschrieben. Es zeigen:

  • Fig. 1 eine schematisierte Seitenansicht einer erfindungsgemäß ausgebildeten Maschine zum Bearbeiten eines Gleises mit einem Gleishebeaggregat,
  • Fig. 2 und 3 jeweils eine vergrößerte Seitenansicht bzw. Draufsicht auf das Gleishebeaggregat, und
  • Fig. 4 eine Ansicht des Gleishebeaggregates in Gleislängsrichtung.
    • The invention will be described in more detail below with reference to a preferred embodiment shown in the drawings. Show it:
  • 1 is a schematic side view of an inventive machine for working a track with a track lift unit,
  • 2 and 3 are each an enlarged side view and top view of the track lifting unit, and
  • Fig. 4 is a view of the track lifting unit in the track longitudinal direction.

    • Eine in Fig. 1 dargestellte Maschine 1 ist zum Bearbeiten einer Schotterbettung 2 eines Gleises 3 ausgebildet und weist einen auf Schienenfahrwerken 4 abgestützten Maschinenrahmen 5 auf. An diesem ist ein Arbeitsaggregat 6 in Form einer rotierbaren, unter dem Gleis 3 hindurchgeführten Räumkette 7 zum Aushub der Schotterbettung 2 gelagert. Der Räumkette 7 sind Förderbänder 8 zum Abtransport des aufgenommenen Schotters zugeordnet. Weitere Förderbänder 9 sind zum Wiedereinbringen von gereinigtem oder neuem Schotter an einer in Arbeitsrichtung der Maschine 1 hinter der Räumkette 7 gelegenen Stelle vorgesehen. Die Arbeitsrichtung ist durch einen Pfeil 10 angedeutet. An den beiden Enden des Maschinenrahmens 5 sind weitere, nicht näher dargestellte Maschinen 11 an die Maschine 1 gekuppelt.A machine 1 shown in Fig. 1 is for processing a ballast bed 2 of a track 3 is formed and has a rail on bogies 4 supported machine frame 5 on. At this is a working aggregate 6 in the form of a rotatable, passed under the track 3 Cutter chain 7 for excavating the ballast bed 2 stored. Of the Reaming chain 7 are conveyor belts 8 for the removal of the recorded Assigned to Schotters. Further conveyor belts 9 are for reintroduction of cleaned or new ballast at a working direction of the machine 1 provided behind the clearing chain 7 location. The working direction is indicated by an arrow 10. At the two ends of the machine frame 5 are further, not shown machines 11 coupled to the machine 1.

    Im Bereich der Räumkette 7 ist am Maschinenrahmen 5 ein Gleishebeaggregat 12 befestigt, dessen Aufbau in weiterer Folge auch anhand der Fig. 2, 3 und 4 deutlicher ersichtlich wird. Das Gleishebeaggregat 12 weist einen Werkzeugrahmen 13 auf, der sich etwa horizontal in Gleisquerrichtung erstreckt. Auf dem Werkzeugrahmen 13 ist ein Gleitträger 17 gelagert, der anhand einer Querführung 18 relativ zum Werkzeugrahmen 13 in Gleisquerrichtung verstellbar ausgebildet und zu diesem Zweck mit einem Verschiebeantrieb 19 verbunden ist. Das Gleishebeaggregat 12 liegt in der (hier gezeigten) Einsatzstellung anhand von Spurkranzrollen 14 auf Laufflächen 15 von Schienen 16 des Gleises 3 auf bzw. rollt auf diesen ab.In the area of the clearing chain 7 is on the machine frame 5, a track lifting unit 12 fixed, the structure in a further consequence also with reference to FIG. 2, 3 and 4 can be seen more clearly. The track lift unit 12 has a Tool frame 13, which is approximately horizontal in the transverse direction of the track extends. On the tool frame 13, a slide carrier 17 is mounted, the basis of a transverse guide 18 relative to the tool frame 13 in Track transverse direction formed adjustable and for this purpose with a Displacement drive 19 is connected. The track lifting unit 12 is located in the insertion position (shown here) on the basis of flange rings 14 Running surfaces 15 of rails 16 of the track 3 on or rolls on this from.

    Im Bereich jeder Schiene 16 weist der Gleitträger 17 jeweils zwei in Maschinenlängsrichtung voneinander distanzierte vertikale Führungssäulen 20 auf, auf denen ein als Hydraulikzylinder 22 ausgebildeter Rollenträger 21 hydraulisch höhenverstellbar gelagert ist. (Als alternative Ausführungsform wäre denkbar, daß die Führungssäule 20 durch den Kolben des Hydraulikzylinders 22 gebildet ist, der dann direkt mit dem Gleitträger 17 verbunden wäre). Auf jedem höhenverstellbaren Rollenträger 21 sind jeweils zwei - ein Paar 23 bildende - Heberollen 24 befestigt, die durch einen Querverstellantrieb 25 in Gleisquerrichtung zueinander beistellbar sind. Somit sind auf dem Gleitträger 17 pro Schiene 16 des Gleises 3 zwei in Schienenlängsrichtung voneinander distanzierte Paare 23 von formschlüssig an die Schiene anlegbaren Heberollen 24 angeordnet, wobei diese Paare 23 jeweils unabhängig voneinander in Bezug auf den Werkzeugrahmen 13 anhand eines durch den Hydraulikzylinder 22 gebildeten Höhenverstellantriebes 26 höhenverstellbar ausgebildet sind. In the region of each rail 16, the sliding support 17 each two in the machine longitudinal direction distanced vertical guide columns 20, on which a designed as a hydraulic cylinder 22 roller carrier 21 is mounted hydraulically height adjustable. (As an alternative embodiment It would be conceivable that the guide column 20 by the piston of the hydraulic cylinder 22 is formed, which then connected directly to the slide 17 would). On each height-adjustable roller carrier 21 are respectively two - a pair of 23 forming - lifting rollers 24 fastened by a Querverstellantrieb 25 in the transverse direction of the track to each other can be provided. Thus, on the slide 17 per rail 16 16 of the track 3 two in Rail longitudinally spaced pairs 23 of form-fitting arranged on the rail lifting rollers 24, wherein these Pairs 23 each independently with respect to the tool frame 13 based on a height adjustment drive formed by the hydraulic cylinder 22 26 are adjustable in height.

    In einer Arbeitskabine 39 ist eine Steuereinrichtung 40 untergebracht (Fig. 1), die mit den Querverstellantrieben 25 und Höhenverstellantrieben 26 der Heberollen 24 in Verbindung steht. Wie an späterer Stelle genauer beschrieben, werden diese Antriebe 25,26 derart gesteuert, daß mit einer Distanzierung der beiden in Gleisquerrichtung nebeneinanderliegenden Heberollen 24 eines Paares 23 voneinander eine automatische Beaufschlagung des zugeordneten Höhenverstellantriebes 26 gekoppelt ist, um die Heberollen 24 in Bezug auf den Werkzeugrahmen 13 abzusenken. Weiters kann über die Steuereinrichtung 40 eine Beaufschlagung des Querverstellantriebes 25 für eine Bewegung beider Heberollen 24 eines Paares 23 zueinander mit einer automatischen Beaufschlagung des zugeordneten Höhenverstellantriebes 26 für ein Anheben beider Heberollen 24 in Bezug auf den Werkzeugrahmen 13 gekoppelt werden.In a work booth 39, a control device 40 is housed (Fig. 1), with the Querverstellantrieben 25 and Höhenverstellantrieben 26th the lifting rollers 24 is in communication. As in more detail later described, these drives 25,26 are controlled so that with a Distancing the two adjacent in the transverse direction of the track Lifting rollers 24 of a pair 23 from each other an automatic loading the associated height adjustment drive 26 is coupled to Lower the lifting rollers 24 with respect to the tool frame 13. Furthermore, via the control device 40, an admission of the Querverstellantriebes 25 for movement of both lifting rollers 24 a Paares 23 to each other with an automatic admission of the associated Höhenverstellantriebes 26 for lifting both lifting rollers 24th coupled with respect to the tool frame 13.

    Das Gleishebeaggregat 12 bzw. der Werkzeugrahmen 13 ist über zwei parallel zueinander und etwa vertikal verlaufende, in Gleisquerrichtung voneinander distanzierte Hebeantriebe 27 höhenverstellbar mit dem Maschinenrahmen 5 verbunden. Zusätzlich ist der Werkzeugrahmen 13 anhand einer Anlenkung 28 um in Gleisquerrichtung verlaufende, horizontale Schwenkachsen 29 verschwenkbar am Maschinenrahmen 5 angelenkt. Diese - in Seitenansicht annähernd parallelogrammförmige - Anlenkung 28 besteht aus zwei Spurstangen 30 und einer deichselartig bzw. T-förmig ausgebildeten Schleppstange 31. Die beiden in Gleisquerrichtung voneinander distanzierten Spurstangen 30 verlaufen in einer gemeinsamen Ebene 32, während die Schleppstange 31 parallel zu dieser Ebene 32, aber von dieser distanziert unterhalb derselben verläuft. Die Schleppstange 31 ist teleskopisch verlängerbar ausgebildet und mit einem Längenverstellantrieb 33 ausgestattet.The track lifting unit 12 or the tool frame 13 is parallel over two to each other and about vertically extending, in track transverse direction of each other distanced lifting drives 27 height adjustable with the machine frame 5 connected. In addition, the tool frame 13 is based on An articulation 28 extending in the transverse direction of the track, horizontal Swivel axes 29 pivotally hinged to the machine frame 5. This - in side view almost parallelogram - articulation 28 consists of two tie rods 30 and a drawbar-like or T-shaped trained tow bar 31. The two in the transverse direction of each other distanced tie rods 30 extend in a common plane 32, while the tow bar 31 parallel to this plane 32, but from this distanced runs below the same. The towbar 31 is designed telescopically extendable and with a length adjustment 33 equipped.

    Die Spurstangen 30 sind an der Oberseite des Werkzeugrahmens 13 in jeweils einer Anlenkstelle 34 gelenkig befestigt, die durch eine in Gleisquerrichtung ausgerichtete und als Schwenkachse 29 dienende Welle 35 gebildet ist. Die Hebeantriebe 27, die mit ihrem oberen Ende 36 am Maschinenrahmen 5 gelagert sind, sind mit ihrem unteren Ende 37 ebenfalls jeweils auf der horizontalen Welle 35 unmittelbar neben der Spurstange 30 gelenkig befestigt. Wie in Fig. 3 zu erkennen ist, sind die beiden Spurstangen 30 spiegelsymmetrisch bezüglich einer vertikalen Längssymmetrieebene 38 der Maschine 1 angeordnet und verlaufen in einem spitzen Winkel zueinander.The tie rods 30 are at the top of the tool frame 13 in each pivotally attached to an articulation point 34, which by a cross-track aligned and serving as a pivot axis 29 shaft 35th is formed. The lift drives 27, with their upper end 36 on the machine frame 5 are stored, with its lower end 37 also each on the horizontal shaft 35 immediately adjacent to the tie rod 30 hinged. As can be seen in Fig. 3, the two tie rods 30 mirror-symmetric with respect to a vertical longitudinal plane of symmetry Arranged 38 of the machine 1 and extend in an acute Angle to each other.

    Im Arbeitseinsatz der Maschine 1 zur Bearbeitung der Schotterbettung 2 wird das Gleishebeaggregat 12 mittels der Hebeantriebe 27 abgesenkt und über die Spurkranzrollen 14 auf den Schienen 16 des Gleises 3 abgestützt. Danach werden die Paare 23 von Heberollen 24 mit Hilfe der Querverstellantriebe 25 bzw. auch der Höhenverstellantriebe 26 mit den Schienen 16 formschlüssig in Eingriff gebracht, wonach das Gleis 3 durch neuerliche Beaufschlagung der Hebeantriebe 27 angehoben werden kann, um unter dem Gleis den nötigen Arbeitsraum für den Einsatz des Arbeitsaggregates 6 bzw. der Räumkette 7 zu schaffen.In labor use of the machine 1 for processing the ballast bed 2 the track lifting unit 12 is lowered by means of the lifting drives 27 and supported on the rails 16 of the track 3 via the flange wheels 14. Thereafter, the pairs 23 of lifting rollers 24 by means of Querverstellantriebe 25 and also the height adjustment drives 26 with the rails 16 positively engaged, after which the track 3 by renewed Actuation of the lifting drives 27 can be raised to under the track, the necessary working space for the use of the working aggregate 6 or the clearing chain 7 to create.

    Zur Herstellung eines formschlüssigen Kontaktes der Heberollen 24 mit den Schienen 16 ist der Längenverstellantrieb 33 der teleskopischen Schleppstange 31 drucklos geschaltet bzw. in Schwimmstellung, um eine Anpassung des Gleishebeaggregates 12 an die Gleislängslage zu erlauben. Der Werkzeugrahmen 13 kann dabei um die durch die Wellen 35 gebildete Schwenkachse 29 rotieren (Fig. 2), da sowohl die Spurstangen 30 als auch die unteren Enden 37 der Hebeantriebe 27 in der gleichen Achse 29 an der Welle 35 angelenkt sind. Nach erfolgter Anpassung der Lage in Gleislängsrichtung bzw. Anlegen der Heberollen 24 an die Schienen 16 wird der Längenverstellantrieb 33 der Schleppstange 31 gesperrt, um das Gleishebeaggegat 12 in Gleislängsrichtung zu stabilisieren und in dieser Position zu halten. For producing a positive contact of the lifting rollers 24 with the rails 16 is the length adjustment 33 of the telescopic Tow bar 31 depressurized or in floating position, to one Allow adjustment of the track lifting unit 12 to the track longitudinal position. The tool frame 13 can be around the waves 35 formed by the Swivel axis 29 rotate (Fig. 2), since both the tie rods 30 and the lower ends 37 of the lifting drives 27 in the same axis 29 are hinged to the shaft 35. After adjusting the situation in Track longitudinal direction or applying the lifting rollers 24 to the rails 16 the Längenverstellantrieb 33 of the tow bar 31 is locked to the Track lift gate 12 to stabilize in track longitudinal direction and in this Hold position.

    Wenn das im Arbeitseinsatz kontinuierlich am Gleis 3 abrollende Gleishebeaggregat 12 auf ein Hindernis trifft, wie es beispielsweise in Fig. 2 und 4 in Form einer Lasche 41 dargestellt ist, so ist es zu deren Überwindung erforderlich, die Heberollen 24 kurzzeitig in Gleisquerrichtung voneinander zu distanzieren und nach Passieren des Hindernisses wieder zu schließen. Die Heberollen 24 eines jeden Paares 23 werden im regulären Arbeitseinsatz mit einem bestimmten Druck zusammengepreßt. Sobald dieser Druck nun durch Auftreffen auf das Hindernis zwangsläufig erhöht wird, wird über die Steuereinrichtung 40 automatisch ein Auseinanderspreizen der beiden Heberollen 24 des betreffenden Paares 23 mittels des Querverstellantriebes 25 ausgelöst. Bei Erreichen der maximal geöffneten Stellung des Heberollenpaares wird ein Anschlag 42 (Fig. 4) betätigt, der eine Beaufschlagung des Höhenverstellantriebes 26 zur Absenkung der Heberollen 24 auslöst.Whenever the track lifting unit rolling continuously on track 3 is in use 12 encounters an obstacle, as for example in Fig. 2 and 4 is shown in the form of a tab 41, so it is to overcome them required, the lifting rollers 24 briefly in the transverse direction of the track from each other to distance and close again after passing the obstacle. The lifting rollers 24 of each pair 23 are in regular work compressed with a certain pressure. As soon as this one Pressure now inevitably increased by hitting the obstacle is, is about the controller 40 automatically spread apart the two lifting rollers 24 of the respective pair 23 by means of Querverstellantriebes 25 triggered. When reaching the maximum open Position of the lifting roller pair, a stop 42 (Fig. 4) is actuated, the a loading of the height adjustment drive 26 for lowering the Lifting rollers 24 triggers.

    In weiterer Folge bewirkt die Steuereinrichtung 40, beispielsweise anhand eines Zeitgliedes in Zusammenhang mit der Vorfahrtgeschwindigkeit der Maschine 1, daß die Heberollen 24 nach Passieren der Problemstelle im Gleis 3 automatisch wieder zusammengeklappt werden, um die Schiene 16 neuerlich zu erfassen.As a result, the control device 40, for example, based a timer in connection with the priority speed of Machine 1, that the lifting rollers 24 after passing the problem in the Track 3 will automatically be folded back up to the rail 16 again to capture.

    Durch die an die Spreizung der Heberollen 24 gekoppelte Absenkung ist also gewährleistet, daß die Schiene 16 nach Überfahren der Lasche 41 sofort und ohne Zeitverlust wieder durch Beistellen des geöffneten Paares 23 von Heberollen 24 sicher erfaßt werden kann. Sicherheitshalber kann das nachfolgende, zweite Paar 23 von Heberollen 24 nur dann geöffnet werden, wenn zuvor das vordere Paar geschlossen worden ist.By coupled to the spreading of the lifting rollers 24 lowering thus ensuring that the rail 16 after passing over the tab 41st Immediately and without loss of time by providing the opened couple 23 of lifting rollers 24 can be detected safely. For safety's sake the subsequent, second pair 23 of lift rollers 24 only then opened when the front pair has been closed.

    Mit dem Zusammenklappen der Heberollen 24 durch den Querverstellantrieb 25 wird ein weiterer Anschlag 43 betätigt (Fig. 4). Dieser bewirkt über die Steuereinrichtung 40, daß mit dem Beaufschlagen des Querverstellantriebes 25 zur Anlage der beiden Heberollen 24 des abgesenkten Paares 23 an die Schiene 16 hinter dem Hindernis auch eine automatische Beaufschlagung des zugeordneten Höhenverstellantriebes 26 ausgelöst wird, um die beiden Heberollen 24 - und damit das Gleis 3 - wieder in die ursprüngliche Position relativ zum Werkzeugrahmen 13 anzuheben und eine störungsfreie Fortsetzung des kontinuierlichen Arbeitseinsatzes der Maschine 1 zu gewährleisten.With the folding of the lifting rollers 24 by the Querverstellantrieb 25, another stop 43 is actuated (FIG. 4). This causes over the control device 40, that with the action of the Querverstellantriebes 25 for conditioning the two lifting rollers 24 of the lowered pair 23 to the rail 16 behind the obstacle and an automatic admission the associated height adjustment drive 26 is triggered, around the two lifting rollers 24 - and thus the track 3 - back to the original Raise position relative to the tool frame 13 and a trouble-free continuation of the continuous work of the machine 1 to ensure.
