Description

Die Erfindung betrifft ein Stütz- und Führungsgerüst für eine Bogenstranggießanlage mit an einem Tragrahmen abgestützten auswechselbaren Stützsegmenten, in denen die Rollen der einander gegenüberliegenden inneren und äußeren Führungsbahn im Abstand voneinander gelagert sind, wobei im Mittelpunkt des Kreisbogens, entlang dessen die Stützsegmente angeordnet sind, ein Schwenkhebel, dessen Länge kürzer ist als der radiale Abstand vom Mittelpunkt zu den Stützsegmenten, mit aus- und einschiebbaren Einrichtungen zum Erfassen und Ausziehen einzelner Stützsegmente gelagert ist.The invention relates to a support and guide frame for a continuous caster with interchangeable support segments supported on a support frame, in which the rollers of the opposing inner and outer guideway are mounted at a distance from each other, a in the center of the arc, along which the support segments are arranged Swivel lever, the length of which is shorter than the radial distance from the center to the support segments, is mounted with extendable and retractable devices for gripping and pulling out individual support segments.

Ein derartiges Stütz- und Führungsgerüst ist in der US-A-3763923 beschrieben. Bei dieser bekannten Konstruktion ist ein Wagen im Schwenkhebel fahrbar angeordnet, der das Führungssegment ergreift und mitnimmt.Such a support and guide frame is described in US-A-3763923. In this known construction, a carriage is movably arranged in the swivel lever, which grips and takes the guide segment with it.

Die Erfindung stellt sich die Aufgabe, eine verbesserte, konstruktiv weniger aufwendige Wechselvorrichtung zu schaffen, ohne daß ein eigener Wagen zur Aufnahme eines Stützsegmentes erforderlich ist, und bei der sichergestellt ist, daß das erfaßte Segment während des Ausbaues sicher gehalten und geführt ist, wobei die Einrichtung auch für Segmente schwerer Bauart eingesetzt werden kann.The invention has for its object to provide an improved, structurally less complex changing device without the need for a separate car to accommodate a support segment, and in which it is ensured that the detected segment is securely held and guided during removal, the Device can also be used for segments of heavy construction.

Diese Aufgabe wird erfindungsgemäß bei einem Stütz- und Führungsgerüst der eingangs erwähnten Art dadurch gelöst, daß am Schwenkhebel teleskopartig ein- und ausschiebbare Führungsschienen vorgesehen sind, die nach Ausschieben in die Strangführungsbahn ein Stützsegment gabelförmig umfassen, wobei am Stützsegment befestigte Gegenführungen mit den Führungsschienen in Eingriff gelangen, worauf das Stützsegment entlang der Führungsschienen aus der Einbaustellung entfernbar ist.This object is achieved according to the invention in a support and guide frame of the type mentioned at the outset in that telescopic guide rails which can be telescoped in and out are provided which, after being pushed out into the strand guide track, comprise a support segment in the form of a fork, with counter guides attached to the support segment engaging with the guide rails reach, whereupon the support segment along the guide rails can be removed from the installation position.

Vorteilhaft sind die Gegenführungen am Stützsegment als Räder oder Rollen ausgebildet.The counter guides on the support segment are advantageously designed as wheels or rollers.

Zweckmäßig sind der Schwenkhebel und die Führungsschienen als C-förmige Profile ausgebildet und sind in der Rückzugsposition im Schwenkhebel und in den Führungsschienen Ausnehmungen zum Durchritt der Gegenführungen vorgesehen.The pivot lever and the guide rails are expediently designed as C-shaped profiles and, in the retracted position, recesses are provided in the pivot lever and in the guide rails for passage of the counter guides.

Nach einer bevorzugten Ausführungsform sind im Mittelpunkt des Kreisbogens eine Seilwinde zum Ausziehen des Stützsegmentes und ein Stelltrieb zum Ein- und Ausschieben der Führungsschienen angeordnet.According to a preferred embodiment, a cable winch for pulling out the support segment and an actuating drive for pushing the guide rails in and out are arranged in the center of the circular arc.

Vorzugsweise ist zum Ein- und Ausschieben der Führungsschienen ein mit dem Schwenkhebel mitbeweglicher hydraulischer Antrieb vorgesehen.A hydraulic drive which is movable with the swivel lever is preferably provided for pushing the guide rails in and out.

Eine weitere Aufgabe, die der Erfindung zugrundeliegt, besteht darin, das Auswechseln der Stützsegmente ohne Verklemmen bewerkstelligen zu können, u.zw. auch dann, wenn die Achsabstände nebeneinanderliegender Rollen sehr gering sind.Another object of the invention is to be able to replace the support segments without jamming, etc. even if the center distances of adjacent rollers are very small.

Diese Aufgabe wird dadurch gelöst, daß an jedem Stützsegment mindestens eine an einem Träger befestigte randseitige Rolle der äußeren Führungsbahn lösbar am Stützsegment befestigt ist, wobei während des Ausbaus des Stützsegmentes der Träger mit der Rolle in eine Ausnehmung am Tragrahmen absetzbar ist.This object is achieved in that at least one edge-mounted roller of the outer guideway attached to a support is detachably attached to the support segment on each support segment, the support with the roller being removable into a recess on the support frame during the removal of the support segment.

Hierdurch ist es möglich, die Rollen in einem sehr geringen Abstand voneinander anzuordnen, ohne daß beim Ausbau eines Stützsegmentes eine Kollision mit einem benachbarten Element eintritt.This makes it possible to arrange the rollers at a very short distance from one another without colliding with an adjacent element when a support segment is removed.

Die Erfindung ist anhand zweier Ausführungsformen in der Zeichnung in schematischer Darstellung erläutert, wobei die fig. 1 bis 4 jeweils eine Seitenansicht (teilweise geschnitten) eines Führungsbogens gemäß einer Ausführungsform zeigen. Fig. 5 stellt eine Ansicht in Richtung des Pfeiles V der Fig. 1 dar. In fig. ist in zu Fig. 1 analoger Darstellung eine andere Ausführungsform dargestellt.The invention is explained using two embodiments in the drawing in a schematic representation, the fig. 1 through 4 each show a side view (partially sectioned) of a guide arch according to an embodiment. Fig. 5 shows a view in the direction of arrow V of Fig. 1. In fig. another embodiment is shown in a representation analogous to FIG. 1.

Auf einem einstückigen kreisbogenförmigen Tragrahmen 1, der am Fundament 2 mittels eines Festlagers und zweier Loslager 4 gelagert ist, sind nach innen zu bearbeitete stützflächen 5 vorgesehen, auf denen jeweils ein Stützsegment 6 abgestützt ist. Der Tragrahmen 1 könnte auch mehrteilig ausgebildet sein, wobei jeder der Teile mittels eines Festlagers und eines Loslagers gegen das Fundament abgestütz ist. Die Stützsegmente 6 besitzen bearbeitete, an die Stützflächen 5 passende Gegenflächen 7, sodaß der Einbau der einzelnen Stützsegmente 6 ohne Passungsarbeit im Austauschfall leicht möglich ist. Zwischen den Stützflächen 5 befindet sich jeweils eine Ausnehmung 8 von etwa trapezförmigem Querschnitt. Am oberen Ende 9 des Tragrahmens 1, an dem das oberste Stützsegment angeordnet ist, befindet sich ebenfalls eine Ausnehmung 10, die einen rechteckigen Querschnitt aufweist.On an integral circular support frame 1 which is supported on the foundation 2 by means of a fixed bearing and two floating bearings 4, support surfaces 5 are provided which are machined inwards and on which a support segment 6 is supported. The support frame 1 could also be constructed in several parts, each of the parts being supported against the foundation by means of a fixed bearing and a floating bearing. The support segments 6 have machined mating surfaces 7 which match the support surfaces 5, so that the installation of the individual support segments 6 is easily possible without fitting work in the event of an exchange. There is a recess 8 of approximately trapezoidal cross section between the support surfaces 5. At the upper end 9 of the support frame 1, on which the uppermost support segment is arranged, there is also a recess 10 which has a rectangular cross section.

In den Stützsegmenten 6, die vorteilhaft untereinander gleichartig ausgestaltet sind, sind die Rollen 11 der inneren Führungsbahn 12 und die Rollen 13 der äußeren Führungsbahn 14 im Abstand voneinander einander gegenüberliegend gelagert, wobei jeweils die randseitige erste Rolle, die mit 16 bezeichnet ist, äußeren Führungsbahn 14 lösbar am Stützsegment 6 befestigt ist, u.zw. derart, daß ihre Lager an einem Querträger 17 angeordnet sind, welcher seinerseits am Stützsegment 6 lösbar befestigt ist.In the support segments 6, which are advantageously configured identically to one another, the rollers 11 of the inner guideway 12 and the rollers 13 of the outer guideway 14 are mounted opposite one another at a distance from one another, with the edge-side first roller, which is denoted by 16, in each case the outer guideway 14 is releasably attached to the support segment 6, etc. such that their bearings are arranged on a cross member 17, which in turn is releasably attached to the support segment 6.

Im Mittelpunkt 18 der kreisbogenförmigen Führungsbahnen 12, 14 ist ein Schwenkhebel19, dessen Länge 20 kürzer ist als der radiale Abstand 21 vom Mittelpunkt zu den Stützsegmenten 6, schwenkbar gelagert. Zum Verschwenken dient ein ortsfest angeordneter Seiltrieb 22, dessen Seil 23 am Ende 24 des Schwenkhebels 19 befestigt ist. Der Schwenkhebel 19 weist zwei im Abstand 26 voneinander angeordnete C-förmige Profile 25 auf, wobei der Abstand 26 etwas größer gehalten ist als die Breite 27 det Stützsegmente 6. In diesen C-förmigen Profilen 25 sind ebenfalls als C-förmige Profile 28 ausgebildete ein- und ausschiebbare Führungsschienen vorgesehen. Zum Aus- und Einschieben dieser Führungsschienen dient jeweils ein im Mittelpunkt 18 drehbar gelagertes antreibbares Ritzel 29, welches in eine an der Unterseite dieser C-förmigen Träger angeordnete Zahnstange eingreift. Anstelle des Ritzels und der Zahnstange könnte auch, wie in Fig. 6 dargestellt, ein Druckmittelzylinder 30 vorgesehen sein. Im Mittelpunkt 18 ist außerdem eine Seilwinde 31 drehbar gelagert, deren Seil 32 an dem auszubauenden Stützsegment 6 befestigbar ist.A pivot lever 19, whose length 20 is shorter than the radial distance 21 from the center point to the support segments 6, is pivotably mounted in the center 18 of the circular guideways 12, 14. A stationary cable drive 22 is used for pivoting, the cable 23 of which is attached to the end 24 of the pivot lever 19. The pivot lever 19 has two C-shaped profiles 25 arranged at a distance 26 from one another, the Distance 26 is kept somewhat larger than the width 27 of the support segments 6. In these C-shaped profiles 25, guide rails which can be inserted and pushed out are also provided as C-shaped profiles 28. A pushable pinion 29, which is rotatably mounted in the center 18 and which engages in a toothed rack arranged on the underside of this C-shaped carrier, is used for pushing out and pushing in these guide rails. Instead of the pinion and the toothed rack, a pressure medium cylinder 30 could also be provided, as shown in FIG. 6. In the center 18, a cable winch 31 is also rotatably mounted, the cable 32 of which can be attached to the support segment 6 to be removed.

Die Funktion der Einrichtung ist folgende :

  • Zunächst wird mittels des Seiltriebes 22 der Schwenkhebel bei dem auszubauenden Stützsegment 6 in Stellung gebracht, wobei die ein-und ausschiebbaren Führungsschienen 28 sich in zurückgezogener Stellung befinden.
The function of the facility is as follows:
  • First, by means of the cable drive 22, the swivel lever is brought into position in the support segment 6 to be removed, the guide rails 28 which can be pushed in and out being in the retracted position.

Bei diesem Stützsegment wird die am Träger 17 gelagerte Rolle 16 vom Stützsegment 6 durch Lösen des Trägers 17 gelöst und der Träger wird mitsamt der Rolle in der am Tragrahmen 1 vorgesehen Ausnehmung 10 befestigt. Die Führungsschienen 28 werden nach außen verschoben, wobei dei Führungschienen 28 mit an den Seiten der Stützsegmente 6 angeordneten Gegenführungen, die als Räder33 ausgebildet sind, in Eingriff gelangen. Sodann wird das Seil 32 am Stützsegment befestigt (Fig. 1). Als nächster Schritt wird, wie aus Fig. ersichtlich ist, das Stützsegment 6 mittels des Seiles 32 zurückgezogen, bis es sich in der in Fig. 2 dargestellten Ausbaustellung befindet. Die Rückzugsbewegung des Stützsegmentes 6 ist durch einen Anschlag 34 begrenzt. Nachfolgend werden die führungsschienen 28 zurückgezogen, bis sie sich in der in Fig.3 dargestellten Rückzugsposition befinden. In dieser Position gelangen an der Oberseite der C-förmigen Profile 25 und 28 angeordnete Ausnehmungen 35 bzw., 36 übereinander. Als nächster Schritt wird der Schwenkhebel 19 in horizontale Stellung geschwenkt, was mittels des seiltriebes 22 erfolgt. Nach Auskuppeln des Seiles 32 aus dem im Schwenkhebel 19 befindlichen Stützsegment 6 kann das Segment, wie in Fig. 4 dargestellt, mittels eines Kranes aus dem Schwenkhebel19 gehoben werden.In this support segment, the roller 16 mounted on the support 17 is detached from the support segment 6 by loosening the support 17 and the support is fastened together with the roller in the recess 10 provided on the support frame 1. The guide rails 28 are displaced outwards, the guide rails 28 engaging with counter guides arranged on the sides of the support segments 6, which are designed as wheels 33. The rope 32 is then attached to the support segment (FIG. 1). As the next step, as can be seen from FIG. 1, the support segment 6 is pulled back by means of the cable 32 until it is in the expanded position shown in FIG. 2. The retraction movement of the support segment 6 is limited by a stop 34. The guide rails 28 are then withdrawn until they are in the retracted position shown in FIG. In this position, recesses 35 and 36 arranged on the top of the C-shaped profiles 25 and 28 pass one above the other. As the next step, the pivot lever 19 is pivoted into the horizontal position, which is done by means of the cable drive 22. After uncoupling the cable 32 from the support segment 6 located in the pivot lever 19, the segment can be lifted out of the pivot lever 19 by means of a crane, as shown in FIG. 4.
