Description

Die Erfindung betrifft eine Einrichtung zum Ausziehen und zum Einbringen eines mit einem Anfahrkopf versehenen flexiblen Anfahrstranges aus bzw. indie bogenförmige Strangführung einer Stranggießanlage, mit einer von der Strangführung abzweigenden, eine Gleit- oder Rollenbahn aufweisenden Anfahrstrangführung und einer Hub- und Transporteinrichtung zum Einführen des Fußendes des Anfahrstranges in die Kokille bzw. in.eine Öffnung der Strangführung unterhalb der Kokille.The invention relates to a device for extracting and introducing a provided with a dummy bar flexible dummy bar from or Indie arcuate Stran g guide of a continuous casting plant, with a branching off the strand guide, a sliding or roller conveyor having Anfahrstrangführung and a lifting and transporting device for introducing the foot end of the start-up strand into the mold or into an opening of the strand guide below the mold.

Nach der AT-PS 343 835 ist eine Einrichtung zum Einbringen eines mit einem Anfahrkopf versehenen flexiblen Anfahrstranges in eine Stranggießanlage bekannt, wobei- der Anfahrstrang von oben durch die Kokille "Fuß voran" in die Strangführung eingefädelt wird. Diese bekannte Einrichtung umfaßt eine Hubeinrichtung zum Erfassen und Anheben des Anfahrstranges und einen eine Gleit- oder Rollenbahn aufweisenden Transportwagen. Der Transportwagen wird von der Aufnahmeposition zum Einlaufteil der Strangführung transportiert und der Fußteil über einen bogenförmigen Endteil des Transportwagens abgesenkt.According to AT-PS 343 835, a device for introducing a flexible starting strand provided with a starting head into a continuous casting installation is known, the starting strand being threaded into the strand guide from above through the mold "foot ahead". This known device comprises a lifting device for detecting and lifting the start-up line and a transport carriage having a slide or roller track. The transport carriage is transported from the receiving position to the inlet part of the strand guide and the foot part is lowered over an arcuate end part of the transport carriage.

Weiters ist nach der DE-PS 1 210 140 eine Aufnahme- und Zuführeinrichtung für den Anfahrstrang einer Stranggießanlage bekannt, bei welchem eine von der Strangführung ; abzweigende Rollenbahn schwenkbar oberhalb der Strangführung angeordnet ist, derart, daß ihr unteres Ende als Weiche wirkt.Furthermore, according to DE-PS 1 210 140, a receiving and feeding device for the starting strand of a continuous caster is known, in which one of the strand guide ; branching roller conveyor is pivotally arranged above the strand guide, such that its lower end acts as a switch.

Die beschriebenen bekannten Einrichtungen haben gewisse Nachteile. Bei der zuerst erwähnten Einrichtung ist die Verwendung eines eigenen Transportwagens mit Schienen mit einem relativ hohen konstruktiven Aufwand verbunden und erfordert zusätzlichen Raum; bei der an zweiter Stelle genannten Einrichtung ist die Einführung des Anfahrstranges "Fuß voran" durch die Kokille nicht möglich, sondern bei dieser Einrichtung muß der Anfahrstrang durch die Strangführung "Kopf voran" zur Kokille zurückbewegt werden, was einen erheblichen Zeitaufwand und damit erhebliche Rüst- bzw. Stillstandzeiten erfordert.The known devices described have certain disadvantages. In the case of the first-mentioned device, the use of an own transport carriage with rails is connected with a relatively high construction effort and requires additional space; In the case of the device mentioned in the second place, it is not possible to introduce the start-up strand "foot forward" through the mold, but in this device the start-up strand must be moved back to the mold by the strand guide "head first", which requires a considerable amount of time and therefore considerable set-up time. or downtimes required.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, eine Einrichtung der eingangs beschriebenen Art zu schaffen, die nur einen geringen konstruktiven Aufwand erfordert und mit der es möglich ist, den Anfahrstrang im Kreislauf nach erfolgtem Gießbeginn mit "Fuß voran" für einen nächsten Gießbeginn der Kokille oder in eine Öffnung der Strangführung unterhalb der Kokille zuzuführen.The invention aims at avoiding these disadvantages and difficulties and has as its object to create a device of the type described at the outset, which requires only little construction effort and with which it is possible to "walk ahead" of the starting line in the circuit after the start of casting has taken place. for the next start of casting the mold or in an opening of the strand guide below the mold.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die von der Strangführung abzweigende Anfahrstrangführung eine in der Strangführung angeordnete kufenartig ausgebildete Weiche und einen um eine horizontale Achse um etwa 1800 drehbaren, eine Gleit- oder Rollenbahn enthaltenden Käfig aufweist.This object is inventively achieved in that the branching off from the strand guide having a Anfahrstrangführung arranged in the strand guide manner of a runner formed soft and a about a horizontal axis through approximately 180 0 rotatable, a sliding or roller conveyor containing cage.

Um die kufenartig ausgebildete Weiche möglichst klein und damit leicht beweglich und platzsparend zu halten, ist zwischen der kufenförmigen Weiche und dem Käfig eine ortsfeste bogenförmige Gleit- oder Rollenbahn vorgesehen.To keep the switch-shaped switch as small as possible and thus easy to move and save space, a fixed arc-shaped slide or roller track is provided between the skid-shaped switch and the cage.

Zweckmäßig enthält die ortsfeste Bahn und der eine Gleit-oder Rollenbahn aufweisende Käfig mindestens jeweils ein Treibrollenpaar, wodurch der Hallenkran zum Ausbringen des Anfahrstranges aus der Strangführung nicht benötigt wird und für andere Arbeiten freigehalten ist.The stationary track and the cage having a slide or roller track expediently each contain at least one pair of drive rollers, as a result of which the overhead crane is not required for pulling the start-up rope out of the rope guide and is kept free for other work.

Nach einer bevorzugten Ausführungsform ist die Drehachse des Käfigs parallel zu seiner Gleit- oder Rollenbahn, quer zu seiner Längsrichtung und außermittig des Käfigs angeordnet.According to a preferred embodiment, the axis of rotation of the cage is arranged parallel to its slide or roller track, transversely to its longitudinal direction and off-center of the cage.

Dadurch ist es möglich, den Käfig in einer Schwenkposition (zur Aufnahme des Anfahrstranges) unterhalb der Gießbühne zu halten und in der anderen Schwenkposition (mit nach oben weisendem Anfahrkopf) mit einem Ende über die Gießbühne ragen zu lassen, sodaß der Anfahrstrang vom Hallenkran leichter erfaßbar ist.This makes it possible to hold the cage in one swivel position (to accommodate the start-up line) below the casting platform and in the other swivel position (with the start-up head pointing upwards) to let one end protrude over the casting platform, so that the start-up line can be more easily grasped by the overhead crane is.

Nach einer weiteren zweckmäßigen Ausführungsform ist der Käfig mittels Transporteinrichtungen, wie einem.Hallenkran von der Aufnahmeposition in die Einfädelposition "Fuß voran" transportierbar.According to a further expedient embodiment, the cage can be transported from the receiving position into the threading position "foot ahead" by means of transport devices, such as an indoor crane.

Die erfindungsgemäße Einrichtung ist anhand der Zeichnung an einem Ausführungsbeispiel näher erläutert, wobei Fig. 1 eine Gesamtansicht einer Stranggießanlage in Verbindung mit der erfindungsgemäßen Einrichtung in schematischer Darstellung in Seitenansicht zeigt. Fig. 2 stellt eine Ansicht in Richtung des Pfeiles II der Fig. 1, jedoch mit um 180° geschwenktem Käfig dar.The device according to the invention is explained in more detail with reference to the drawing using an exemplary embodiment, wherein FIG. 1 shows an overall view of a continuous casting installation in connection with the device according to the invention in a schematic representation in a side view. Fig. 2 shows a view in the direction of arrow II of FIG. 1, but with the cage pivoted through 180 °.

In Fig. 1 ist mit 1 eine Durchlaufkokille bezeichnet, an die nach unten zu die Strangführung anschließt. 2 ist die Biegezone der Strangführung, in der der gegossene Strang aus der Vertikalen in einen Kreisbogen gebogen wird. In dem an die Biegezone anschließenden kreisbogenförmigen Führungsgerüst 3 sind die Stütz- und Führungsrollen 4 in einzeln aus- und einbaubaren Segmenten 5 gelagert. Der Anfahrstrang muß von oben durch die Kokille 1 so weit in die Strangführung eingebracht werden, daß die ersten der antreibbaren Rollen 6 ihn ergreifen und ihn nach unten zu ausfördern. Mit 7 ist die Richtzone der Strangführung bezeichnet, in der der kreisbogenförmig gebogene Gußstrang gerade gerichtet wird. 8 ist ein horizontales Strangführungsgerüst. Zwischen der Richtzone 7 und dem horizontalen Strangführungsgerüst 8 sind Treibrollen 9 vorgesehen. Am Ende der horizontalen Führungsstrecke befinden sich weitere Treibrollen 10. An diese schließt der Brennschneidrollgang 11 an, an dem eine nicht dargestellte Brennschneideinrichtung vorgesehen ist, die den Gußstrang in die gewünschten Längen trennt und die auch zum Abschneiden der Schopfenden dient.In Fig. 1, 1 is a continuous mold, to which the strand guide connects downward. 2 is the bending zone of the strand guide, in which the cast strand is bent from the vertical into a circular arc. In the circular-arc-shaped guide frame 3 adjoining the bending zone, the support and guide rollers 4 are mounted in segments 5 which can be removed and installed individually. The start-up line must be inserted into the strand guide from above through the mold 1 so that the first of the drivable rollers 6 grip it and convey it downward. With 7 the straightening zone of the strand guide is designated, in which the arcuate bent cast strand is being straightened. 8 is a horizontal strand guide. Drive rollers 9 are provided between the straightening zone 7 and the horizontal strand guide frame 8. At the end of the horizontal guide section there are further drive rollers 10. This is followed by the flame cutting roller table 11, on which a flame cutting device, not shown, is provided, which separates the cast strand into the desired lengths and which also serves to cut off the ends of the crop.

Am Beginn des Brennschneidrollganges ist eine kufenarig ausgebildete Weiche 12 aus der in Fig. 1 mit vollen Linien dargestellten Position A in die in Fig. 1 mit strichlierten Linien dargestellte Position B um eine ortsfeste Achse 13 schwenkbar angeordnet. Zum Schwenken dient ein Druckmittelzylinder 14.At the beginning of the flame cutting roller table, a switch 12 designed as a skid is arranged so that it can pivot from a position A shown in full lines in FIG. 1 to position B shown in broken lines in FIG. 1 about a fixed axis 13. A pressure medium cylinder 14 is used for pivoting.

Wie aus Fig. 1 ersichtlich ist, schließt an die hochgeschwenkte Weiche 12 (Position B) eine ortsfeste, an einem Stützgerüst 15 montierte Rollenbahn 16 an. Am oberen Ende dieser ortsfesten Rollenbahn 16 ist in Verlängerung derselben ein ebenfalls eine Rollenbahn 17 enthaltender Käfig 18 vorgesehen, der um die mit 19 bezeichnete Achse am Stützgerüst 15 drehbar gelagert ist. Zum Drehen des Käfigs 18 dient der aus Fig. 2 ersichtliche Antriebsmotor 20, dem ein Getriebe 21 vorgeschaltet ist. An den beiden Enden 22, 23 des Käfigs sind Klemmwalzen 24 vorgesehen, die zum Festklemmen des aus aneinander angelenkten Gliederkörpern 25 bestehenden Anfahrstranges 26 dienen. Zum Hochfördern des Anfahrstranges 26, wenn dieser von den letzten vor dem Brennschneidrollgang angeordneten Treibrollen 10 ausgefördert wird, dienen Treibrollengerüste 27, von denen eines an der ortsfesten Rollenbahn 16 und eines etwa in der Mitte des Käfigs 18 vorgesehen ist.As can be seen from FIG. 1, the swiveled switch 12 (position B) is followed by a stationary roller conveyor 16 mounted on a support frame 15. At the upper end of this fixed roller conveyor 16, a cage 18, which also contains a roller conveyor 17, is provided in the extension thereof, which is rotatably mounted on the support frame 15 about the axis 19. The drive motor 20 shown in FIG. 2, to which a gear 21 is connected upstream, is used to rotate the cage 18. At the two ends 22, 23 of the cage, clamping rollers 24 are provided, which are used to clamp the starting strand 26 consisting of articulated link bodies 25. Drive roller stands 27, one of which is provided on the stationary roller conveyor 16 and one approximately in the middle of the cage 18, are used to convey the starting strand 26 when it is being conveyed out by the last drive rollers 10 arranged in front of the flame cutting roller table.

Ganz am Anfang des Brennschneidrollganges ist ein Zangenöffnungsmechanismus 28 angeordnet, mit dem ein zangenförmig ausgebildeter Anfahrkopf 29 des Anfahrstranges aufgeklappt werden kann. In der Gießhalle ist auf Trägern 30 ein Hallenkran 31, der als Portalkran ausgebildet ist, verfahrbar.At the very beginning of the flame cutting roller table there is a pincer opening mechanism 28 with which a pincer-shaped starting head 29 of the starting strand can be opened. A hall crane 31, which is designed as a gantry crane, can be moved on supports 30 in the casting hall.

Die Funktion der erfindungsgemäßen Einrichtung ist folgende:The function of the device according to the invention is as follows:

Zu Gießbeginn wird der mit seinem Anfahrkopf 29 am Kranhaken 32 des Hallenkrans 31 hängende Anfahrstrang 26 "Fuß voran" (der Fuß ist mit 33 bezeichnet) durch die Kokille 1 hindurch in die Strangführung eingefädelt, bis der Anfahrkopf die Kokille nach unten zu abschließt. Dieser Vorgang ist in Fig. 1 mit strichlierten Linien veranschaulicht. Nach Gießbeginn wird der Anfahrstrang mittels der angetriebenen Stützrollen 6 und mit ihm der Gußstrang ausgezogen. Sobald der Fuß 33 des Anfahrstranges von den Treibrollen 10 erfaßt ist, wird die kufenffrmige Weiche 12 in die in Fig. 1 strichliert dargestellte Position B geschwenkt, sodaß der Anfahrstrang über die Weiche der ortsfesten, bogenförmigen Rollenbahn 16 zugeleitet wird. Sobald der Anfahrkopf 29 unter den Zangenöffnungsmechanismus 28 zu liegen kommt, werden die Zangenhälften des Anfahrkopfes aufgeklappt und der so vom Gußstrang getrennte Anfahrstrang mittels des Treibrollengerüstes 27, das an der ortsfesten Rollenbahn 16 vorgesehen ist, weiter in die Höhe gefördert. Wenn der Kopf 29 des Anfahrstranges an der ortsfesten Rollenbahn zu liegen kommt, wird die Weiche 12 wieder nach unten in die Position A geklappt, sodaß die Weiche dem weiter ausgeförderten Gußstrang nicht hinderlich ist. Der Anfahrstrang wird sodann weiter in die Höhe gefördert, bis er zur Gänze im Käfig 18 zu liegen kommt. Dies ist in Fig. 1 mit voll ausgezogenen Linien dargestellt. Der Anfahrkopf 29 und der Fuß 33 des Anfahrstranges sind von den Klemmwalzen 24, der mittlere Teil von den Treibrollen des Treibrollengerüstes 27 gehalten.At the start of casting, the start-up strand 26 "foot ahead" (the foot is designated 33) with its start-up head 29 hanging on the crane hook 32 of the overhead crane 31 is threaded through the mold 1 into the strand guide until the start-up head closes the mold down. This process is illustrated in Fig. 1 with dashed lines. After the start of casting, the starting strand is pulled out by means of the driven support rollers 6 and with it the cast strand. As soon as the foot 33 of the start-up line is gripped by the drive rollers 10, the skid-shaped switch 12 is pivoted into the position B shown in broken lines in FIG. 1, so that the start-up line is fed via the switch to the fixed, curved roller conveyor 16. As soon as the start head 29 under the pincer opening mechanism 28 comes to rest, the pincer halves of the starting head are opened and the starting strand, which is separated from the cast strand, is conveyed further upwards by means of the drive roller stand 27, which is provided on the stationary roller conveyor 16. When the head 29 of the start-up strand comes to rest on the stationary roller conveyor, the switch 12 is folded down again into position A, so that the switch does not hinder the cast strand which is conveyed further. The start-up line is then conveyed further up until it comes to rest entirely in the cage 18. This is shown in Fig. 1 with full lines. The start head 29 and the foot 33 of the start strand are held by the pinch rollers 24, the middle part by the drive rollers of the drive roller stand 27.

Will man nun den Anfahrstrang abermals in die Kokille einfädeln, so wird zunächst der Käfig 18 um 180 geschwenkt, sodaß der zuerst mit seinem Fuß 33 nach oben ragende Anfahrstrang nunmehr mit seinem Anfahrkopf 29 nach oben ragt (Fig. 2). Sodann wird der Anfahrkopf 29 vom Kranhaken 32 des Hallenkranes erfaßt und der Anfahrstrang, wie in Fig. 2 mit strichpunktierten Linien dargestellt ist, aus dem Käfig herausgezogen, worauf der Hallenkran 31 über die Kokille 1 fährt, wie mit strichlierten Linien in Fig. 1 eingezeichnet ist.If you now want to thread the start-up line again into the mold, the cage 18 is first pivoted by 180, so that the start-up line, which initially protrudes with its foot 33, now projects upwards with its start-up head 29 (FIG. 2). Then the start head 29 is gripped by the crane hook 32 of the hall crane and the start line, as shown in FIG. 2 with dash-dotted lines, is pulled out of the cage, whereupon the hall crane 31 moves over the mold 1, as shown with dashed lines in FIG. 1 is.

Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt, sondern kann in verschiedener Hinsicht modifiziert werden.The invention is not limited to the exemplary embodiment shown, but can be modified in various ways.

Beispielsweise ist es möglich, auf die ortsfeste, bogenförmige Rollenbahn zu verzichten, wenn die kufenartig ausgebildete Weiche den Anfahrstrang um etwa 90° abbiegt. Es kann der Käfig direkt an die Weiche angeschlossen wenden. Weiters ist es möglich, die in denFor example, it is possible to dispense with the fixed, curved roller conveyor if the switch, which is designed like a skid, bends the starting strand by approximately 90 °. The cage can turn directly connected to the switch. Furthermore, it is possible that in the

Figuren dargestellten Rollenbahnen für den Anfahrstrang durch Gleitbahnen zu ersetzen. Der Käfig selbst kann um 180 jeweils hin- und hergeschwenkt werden, wie die Pfeile 34 andeuten, oder auch um 3600 gedreht werden. Die Drehachse 19 des Käfigs muß nicht, wie in Fig. 1 dargestellt, genau mittig und parallel zu einer Rolle der Rollenbahn des Käfigs angeordnet sein, sondern sie kann auch außermittig des Käfigs liegen, wodurch der Käfig in einer Lage (zur Aufnahme des Anfahrstranges) mit seinem Ende 22 unterhalb der Gießbühnenebene 35 zu liegen kommt und in der anderen, um 1800 geschwenkten Lage (zwecks Erfassen des Anfahrkopfes mittels des Kranhakens) mit seinem dem Anfahrkopf 29 zugeordneten Ende 23 oberhalb der Gießbühne 35 zu liegen kommt. Dies hat den Vorteil, daß der Anfahrkopf 29 leichter erfaßbar ist.Figures shown to replace roller tracks for the starting strand by slideways. The cage can be toggled 180, respectively, and hergeschwenkt, as indicated by the arrows 34, or can be rotated 360 0th The axis of rotation 19 of the cage need not, as shown in FIG. 1, be arranged exactly in the middle and parallel to a roller of the roller conveyor of the cage, but it can also be located off-center of the cage, as a result of which the cage is in one position (for receiving the starting strand) with its end 22 comes to lie below the Gießbühnenebene 35 and comes to rest in the other, 0 180 pivoted position (for the purpose of detecting the dummy bar by means of the crane hook) with its end facing the dummy bar 29 associated with end 23 above the casting floor 35th This has the advantage that the starting head 29 is easier to grasp.

Eine weitere Modifikation der erfindungsgemäßen Einrichtung kann darin bestehen, daß der Käfig 18 selbst vom Kran angehoben und zur Kokille 1 gefördert wird, wobei während des horizontalen Verfahrens des Käfigs in Richtung zur Kokille der Käfig geschwenkt werden kann.Another modification of the device according to the invention can consist in that the cage 18 itself is lifted by the crane and conveyed to the mold 1, wherein the cage can be pivoted in the direction of the mold during the horizontal movement of the cage.

Der Käfig selbst muß nicht, wie in Fig. 1 dargestellt, zur Aufnahme des Anfahrstranges senkrecht stehen, sondern er kann dazu auch geneigt angeordnet sein, wodurch sich beim Verschwenken des Käfigs (zwecks "nach oben Richten" des Anfahrkopfes) von 1800 abweichende Schwenkwinkel ergeben.The cage itself need not, as shown in FIG. 1, perpendicular to the recording of the dummy bar, but may to be arranged inclined, whereby ( "upwardly directing" the dummy bar for the purpose) of 180 0 deviating during pivoting of the cage pivot angle surrender.

Nach einer weiter abgewandelten Ausführungsform kann die Kokille und gegebenenfalls auch ein Strangführungsteil darunter entfernt werden, bevor der Anfahrstrang in die Strangführung eingefädelt und eingezogen wird. Es kann auch ein Teil der Strangführung zur Freigabe einer Einfädelöffnung aufklappbar gestaltet sein.According to a further modified embodiment, the mold and possibly also a strand guide part below it can be removed before the start-up strand is threaded into the strand guide and drawn in. A part of the strand guide can also be designed to be openable in order to release a threading opening.
