Description

Stütz- und Führungsgerüst für eine BogenstranggießanlageSupport and guide scaffold for a continuous caster

Die Erfindung betrifft ein Stütz- und Führungsgerüst für eine Bogenstranggießanlage mit Stützsegmenten, in denen die Rollen der einander gegenüberliegenden inneren und äußeren Führungsbahn im Abstand voneinander gelagert sind, wobei die Stützsegmente von der Bogenaußenseite ausbaubar und austauschbar sind.The invention relates to a support and guide frame for a continuous sheet caster with support segments in which the rollers of the opposing inner and outer guideway are mounted at a distance from one another, the support segments being removable and replaceable from the outside of the arch.

Einrichtungen solcher Art sind bereits bekannt und beispielsweise in der DE-AS 1 920 757 beschrieben. Die von der Bogenaußenseite her austauschbaren Führungssegmente haben den Vorteil, daß die einzelnen Rollen in einem geringeren Achsabstand voneinander angeordnet werden können, was bei breiten Brammen wichtig ist. Bei von der Bogeninnenseite her ausbaubaren Segmenten sind größere Achsabstände der Rollen erforderlich, um ein Verklemmen der Stützsegmente beim Ausbau zu vermeiden.Devices of this type are already known and are described, for example, in DE-AS 1 920 757. The interchangeable guide segments from the outside of the sheet have the advantage that the individual rollers can be arranged at a smaller axial distance from each other, which is important for wide slabs. In the case of segments that can be removed from the inside of the bend, larger center distances of the rollers are required in order to avoid jamming of the support segments during removal.

Bei dem oben erwähnten bekannten Stütz- und Führungsgerüst ist parallel zur Strangführungsbahn eine Schienenführung für eine Ausbauvorrichtung bzw. Tragvorrichtung im Abstand zur Unterseite des Stützrollengerüstes vorgesehen. Diese Ausbauvorrichtung besteht aus einem mit Rädern an der Schienenführung fahrbaren Rahmen und einem Hydraulikzylinder, der die Segmente aus der Einbau-Stel- . lung herauszieht. Das ausgebaute Stützsegment wird sodann an der Schienenführung nach abwärts bewegt, deren letzter Teil in die Horizontale klappbar ist. Von dort wird das Stützsegment samt der Ausbau- bzw. Tragvorrichtung in eine auf dem horizontalen Auslauf angeordnete Aufnahmeposition gebracht und von einem Kran abgenommen. Der Einbau erfolgt in umgekehrter Reihenfolge.In the known support and guide frame mentioned above, a rail guide for an expansion device or support device is provided parallel to the strand guide track at a distance from the underside of the support roller frame. This expansion device consists of a frame that can be driven by wheels on the rail guide and a hydraulic cylinder that separates the segments from the installation position. lung pulls out. The expanded support segment will be like this then moved downwards on the rail guide, the last part of which can be folded into the horizontal. From there, the support segment together with the removal or carrying device is brought into a receiving position arranged on the horizontal outlet and removed by a crane. Installation is the reverse order.

Die bekannte Konstruktion ist, wie ersichtlich, sehr aufwendig, weil sie eine eigene fahrbare Ausbau- bzw. Tragvorrichtung benötigt, mit der das Stützsegment bis in die Aufnahmeposition transportiert werden muß. Weitere Schwierigkeiten ergeben sich auch dadurch, daß an der Außenseite des Bogens eine Anzahl von bewegten bzw. angetriebenen Einrichtungen vorhanden sein müssen, die Verzunderungen und Verschmutzungen unterliegen.The known construction is, as can be seen, very complex because it requires its own mobile removal or carrying device with which the support segment has to be transported to the receiving position. Further difficulties also arise from the fact that on the outside of the arch there must be a number of moving or driven devices which are subject to scaling and contamination.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, den Ausbau bza. den Austausch von Stiazsegmenten von der Bogenaußenseite mit konstruktiv einfachen Mitteln bewerkstelligen zu können, ohne eine eigene Tragvorrichtung für die Stützelemente vorsehen zu müssen.The invention aims to avoid these disadvantages and difficulties and has the task of expanding or. to be able to carry out the exchange of stia segments from the outside of the arch with structurally simple means without having to provide a separate supporting device for the supporting elements.

Diese Aufgabe wird bei einem Stütz- und Führungsgerüst der eingangs bezeichneten Art dadurch gelöst, daß die einzelnen Stützsegmente auf Schienen zu Aufnahmepositionen verfahrbar sind, welche Aufnahmepositionen an der Rückseite des Bogens in verschiedener Höhenlage, vorzugsweise stufenförmig versetzt zueinander angeordnet sind.This object is achieved in a support and guide frame of the type described in the introduction in that the individual support segments can be moved on rails to receiving positions, which receiving positions on the back of the sheet are arranged at different heights, preferably offset in steps from one another.

Vorteilhaft sind die Schienen zweiteilig ausgebildet, wobei ihr dem Bogen zugewandter vorderer Teil radial und ihr hinterer Teil horizontal verläuft.The rails are advantageously constructed in two parts, their front part facing the arc running radially and their rear part horizontally.

Zweckmäßig sind die Stützsegmente in der eingebauten gießbereiten Stellung durch Konsolen gegenüber dem Anlagentragwerk festgelegt.The support segments are expediently fixed in the installed, ready-to-cast position by brackets opposite the system structure.

Die Erfindung wird an einem Ausführungsbeispiel in der Zeichnung näher erläutert, wobei die Fig. 1 eine schematische Darstellung der Anlage in Seitenansicht, Fig. 2 die Ansicht eines Stützsegmentes in ausgefahrener Stellung in der Aufnahme- bzw. Abhebeposition und Fig. 3 eine Draufsicht auf das Stützsegment in Richtung des Pfeiles III der Fig. 2 zeigen. Fig. 4 ist eine Ansicht in Richtung des Pfeiles IV der Fig. 1.The invention is explained in more detail using an exemplary embodiment in the drawing, in which Fig. 1 is a schematic representation of the system in side view, Fig. 2 is the view of a support segment in the extended position in the receiving or lifting position and Fig. 3 is a plan view of the Show support segment in the direction of arrow III of FIG. 2. FIG. 4 is a view in the direction of arrow IV of FIG. 1.

In Fig. 1 sind mit 1, 2, 3 und 4 aufeinanderfolgende Stützsegmente im Kreisbogenbereich der Strangbogenführung bezeichnet-, wobei jedes Stützsegment gegenüberliegende Rollenbahnen 5, 6 aufweist, die von im Abstand voneinander angeordneten Rollen 7, 8 gebildet werden. Die einzelnen Segmente sind aus ihrer eingebauten Position lösbar und entlang der Schienen 9 bzw. 10 bzw. 11 bzw. 12 ausfahrbar. Die Schienen bestehen aus einem führungsbahnseitigen radialen Teil 9' bzw. 10' bzw. 11' bzw. 12' und einem daran anschließenden horizontalen Teil 9", 10", 11" und 12". Diese horizontalen Schienenteile liegen in verschiedener Höhenlage und vorteilhaft auch in horizontaler Richtung stufenförmig bzw. treppenartig zueinander versetzt, sodaß die Aufnahme- und Abhebepositionen, die mit A, A' und A" bezeichnet sind, von einem Kran ohne gegenseitige Störung bedient werden können.In Fig. 1, 1, 2, 3 and 4 successive support segments in the circular arc region of the strand arch guide are designated, each support segment having opposite roller tracks 5, 6 which are formed by rollers 7, 8 arranged at a distance from one another. The individual segments can be released from their installed position and can be extended along the rails 9 or 10 or 11 or 12. The rails consist of a radial part 9 'or 10' or 11 'or 12' on the guideway side and an adjoining horizontal part 9 ", 10", 11 "and 12". These horizontal rail parts are at different heights and advantageously also offset in the horizontal direction step-like or step-like, so that the pick-up and lift-off positions, which are designated by A, A 'and A ", can be operated by a crane without mutual interference.

In Fig. 2 ist das Segment 2 in der ausgebauten Stellung in Position A' dargestellt. Das Stützsegment besteht im wesentlichen aus einem Rahmen 13, dem äußeren Querträger 14 und dem inneren Querträger 15, den Rollenträgern 16 und 17 mit den Rollen 7 und 8. Auf den Trägern 14 und 15 sind Aufhängelaschen 18 und 19 angeordnet. Mit 20 sind Einstelleinrichtungen für den Rollenabstand bezeichnet. Am Rahmen 13 sind beidseitig des Segmentes Laufräder 21 befestigt, die auf im Querschnitt winkelförmigen Schienen, 10 geführt sind.2 shows the segment 2 in the removed position in position A '. The support segment consists essentially of a frame 13, the outer cross member 14 and the inner cross member 15, the roller carriers 16 and 17 with the rollers 7 and 8. On the carriers 14 and 15, suspension brackets 18 and 19 are arranged. With 20 are Adjustments for the roller spacing called. On the frame 13, impellers 21 are fastened on both sides of the segment and are guided on rails 10 which are angular in cross section.

In Fig. 4 ist das Segment 2 in eingebauter, d.h. gießbereiter Position gezeigt, wobei es durch Konsolen 22 am Anlagentragwerk 23 festgelegt ist.In Fig. 4, segment 2 is built in, i.e. Shown ready position shown, wherein it is fixed by brackets 22 on the system structure 23.

Zum Ausbau des Stützsegmentes aus dem Führungsbogen bzw. zum Einbau des Stützsegmentes in den Führungsbogen ist, wie ersichtlich, keine eigene fahrbare Trägervorrichtung erforderlich. Nach Lösen der Schrauben 24 bzw. anderer geeigneter Verbindungsmittel, mit denen die Konsolen mit dem Stützsegment verbunden sind, kann das Stützsegment entlang des radial geneigten Schienenstückes 10' ausgefahren werden, wobei ein eigener Antrieb nicht erforderlich ist. Es genügt eine im Zentrum des Kreisbogens angeordnete (hier nicht dargestellte) Seilwinde, mit der das Stützsegment beim Ausfahren gebremst und beim Einfahren gezogen wird. Für den Transport im horizontalen Teilstück 10 genügen einfachste übliche Zugvorrichtungen.As can be seen, no separate mobile support device is required to remove the support segment from the guide arch or to install the support segment in the guide arch. After loosening the screws 24 or other suitable connecting means with which the brackets are connected to the support segment, the support segment can be extended along the radially inclined rail section 10 ', a separate drive not being necessary. A cable winch (not shown here) arranged in the center of the circular arc is sufficient, with which the support segment is braked when it is extended and pulled when it is retracted. The simplest conventional pulling devices are sufficient for transport in the horizontal section 10.
