Description

Die Erfindung betrifft ein Stütz- und Führungsgerüst gemäß dem Oberbegriff des Anspruches 1.The invention relates to a support and guide frame according to the preamble of claim 1.

Stütz- und Führungsgerüste dieser Art sind bereits aus der DE-C Nr. 2 425 883 bekannt. Bei diesem bekannten Gerüst ist je Stützsegment eine von diesem unabhängige randseitige Rolle vorgesehen, die in Lagerböcken am Tragrahmen montiert ist, wobei die Lagerböcke mit Justiereinrichtungen zum Ausrichten dieser separaten Rolle versehen sind. Die einzelnen Stützsegmente werden im Reparaturfall entlang von Ausbauschienen ohne separate Rolle zwischen benachbarten Stützsegmenten hochgezogen und dann mit einem Kran zur Werkstätte geführt. Reparierte oder Austauschsegmente werden in gleicher Weise ohne separate Rolle zwischen benachbarten Stützsegmenten über die Ausbauschienen wiederum eingesetzt, wobei die Schwierigkeit besteht, daß eine Justierung der am Tragrahmen montierten Rolle notwendig ist.Support and guide frames of this type are already known from DE-C No. 2 425 883. In this known scaffolding, an independent edge-side roller is provided for each support segment, which is mounted in bearing blocks on the supporting frame, the bearing blocks being provided with adjusting devices for aligning this separate roller. In the event of a repair, the individual support segments are pulled up along extension rails without a separate roller between adjacent support segments and then taken to the workshop with a crane. Repaired or replacement segments are used in the same way without separate roles between adjacent support segments on the expansion rails, with the difficulty that an adjustment of the role mounted on the support frame is necessary.

Die Erfindung bezweckt die Vermeidung dieser Schwierigkeit und stellt sich die Aufgabe, ein Stütz- und Führungsgerüst für eine Bogenstranggießanlage zu schaffen, mit dem eine rasche Auswechselbarkeit der einzelnen Stützsegmente nach der Innenseite des Bogens möglich ist, und wobei alle Rollen des Stützsegmentes eine justierte Einheit darstellen, ohne daß beim neu eingebauten Stützsegment Justierarbeiten an dessen randseitiger bzw. randseitigen Rolle bzw. Rollen nötig sind.The invention aims at avoiding this difficulty and has as its object to create a support and guide frame for a continuous sheet caster, with which the individual support segments can be quickly exchanged towards the inside of the arch, and all the rollers of the support segment constitute an adjusted unit without adjustment work on the edge-side or edge-side roller or rollers of the newly installed support segment.

Die Erfindung löst die Aufgabe durch die Merkmale des kennzeichnenden Teiles des Anspruches 1.The invention solves the problem by the features of the characterizing part of claim 1.

Vorteilhaft ist der Querträger nach Lösung vom Stützsegment in eine Ausnehmung am Tragrahmen absetzbar.The cross member can advantageously be placed in a recess on the support frame after being released from the support segment.

Die Erfindung wird an einem Ausführungsbeispiel näher erläutert, wobei die Fig. 1 eine schematische Seitenansicht eines Teiles des Führungsbogens, der einen kreisförmigen Querschnitt aufweist, im eingebauten, d. h. im gießbereiten Zustand zeigt. In Fig. 2 ist eine ähnliche Darstellung während des Ausbaues eines Stützsegmentes gezeigt.The invention is explained in more detail using an exemplary embodiment, wherein FIG. 1 is a schematic side view of a part of the guide arch, which has a circular cross section, in the built-in, ie. H. shows in the ready-to-pour condition. 2 shows a similar illustration during the removal of a support segment.

In Fig. 1 sind mit 1 und 2 benachbarte Teile des Tragrahmens gezeigt, die bei 3 in einem schwenkbaren Festlager und bei 4 in einem Loslager an einem Bolzen 5 gelagert sind. Der hakenförmige Teil 6 dieser Tragrahmenteile enthält einen in Richtung der Krümmung bzw. Tangente des Bogens gerichteten Schlitz, so daß bei Wärmeeinwirkung eine Ausdehnung der Tragrahmenteile ohne Versetzungen erfolgen kann. Die Tragrahmenteile enthalten nach innen zu bearbeitende Stützflächen 7, 7', an denen sich jeweils ein Stützsegment 8, 8' abstützt. Diese Stützsegmente besitzen bearbeitete, an die Stützflächen 7, 7' passende Gegenflächen 9, 9', so daß der Einbau der einzelnen Segmente ohne Passungsarbeit im Austauschfall leicht möglich ist. Zwischen den Stützflächen 7, 7' befindet sich eine Tasche 10 von trapezförmigem Querschnitt. Eine weitere Tasche 11 bzw. Ausnehmung von rechteckigem Querschnitt befindet sich jeweils an der Stirnseite benachbarter Stützsegmente. In den Stützsegmenten 8, 8' sind die Rollen 12 der Innenbahn und die Rollen 13 der Außenbahn im Abstand voneinander gegenüberliegend gelagert, wobei jeweils die randseitige erste Rolle, die mit 14 bezeichnet ist, lösbar am Stützsegment befestigt ist, und zwar derart, daß sie an einem Querträger 15 gelagert ist, welcher seinerseits mit Schrauben 16 am Segment befestigbar ist. Es können jedoch statt nur einer Rolle auch zwei oder mehrere Rollen der äußeren Führungsbahn am Querträger 15 montiert sein, was dann vorteilhaft ist, wenn bei enger Rollenteilung und großen Strangdicken die Platzverhältnisse beengt sind. Ebenso ist es natürlich möglich, statt einlaufseitiger Rollen auslaufseitige lösbar zu gestalten.In Fig. 1 with 1 and 2 adjacent parts of the support frame are shown, which are mounted at 3 in a pivotable fixed bearing and at 4 in a floating bearing on a bolt 5. The hook-shaped part 6 of these support frame parts contains a slot directed in the direction of the curvature or tangent of the arc, so that the support frame parts can expand without dislocations when exposed to heat. The support frame parts contain support surfaces 7, 7 'to be machined inwards, on each of which a support segment 8, 8' is supported. These support segments have machined counter surfaces 9, 9 'which match the support surfaces 7, 7', so that the installation of the individual segments is easily possible without fitting work in the event of an exchange. There is a pocket 10 of trapezoidal cross-section between the support surfaces 7, 7 '. Another pocket 11 or recess of rectangular cross section is located on the end face of adjacent support segments. In the support segments 8, 8 ', the rollers 12 of the inner web and the rollers 13 of the outer web are mounted opposite one another at a distance from one another, the edge-side first roller, which is designated by 14, being releasably attached to the support segment, in such a way that it is is mounted on a cross member 15, which in turn can be fastened to the segment with screws 16. However, instead of just one roller, two or more rollers of the outer guideway can also be mounted on the cross member 15, which is advantageous if the space is tight with narrow roller division and large strand thicknesses. It is of course also possible to design releasable on the outlet side instead of rollers on the inlet side.

Die Querträger 15 liegen im eingebauten, gießbereiten Zustand, wie in Fig. 1 gezeigt, den Taschen 10 bzw. 11 gegenüber. Beim Ausbau eines Stützsegmentes, wie in Fig. 2 gezeigt, wird der Querträger 15 mit der Rolle 14 vom Stützsegment gelöst und in die Tasche 10 abgesetzt. Sodann kann das Stützsegment 8' auf Ausbauschienen 17 geführt ausgebaut werden, worauf der zwischenzeitlich abgesetzte Querträger 15 mit der Rolle 14 nachgeholt werden kann. Dieser Querträger mit der Rolle 14 kann vorteilhaft seitlich aus der Anlage herausgezogen werden. In der Werkstätte werden die Rollen des Ausbaustützsegmentes 8' nachgearbeitet und die Rolle 14 bei dieser Nacharbeitung mitangepaßt, so daß zwischen der lösbaren und den übrigen Rollen keine Versetzungsstellen vorkommen können.The cross members 15 lie in the installed, ready-to-cast state, as shown in FIG. 1, opposite the pockets 10 and 11, respectively. When a support segment is removed, as shown in FIG. 2, the cross member 15 with the roller 14 is released from the support segment and placed in the pocket 10. The support segment 8 'can then be removed in a guided manner on expansion rails 17, whereupon the cross member 15 which has meanwhile been offset can be made up for with the roller 14. This cross member with the roller 14 can advantageously be pulled laterally out of the system. In the workshop, the rollers of the support segment 8 'are reworked and the roller 14 is also adapted during this reworking, so that no dislocation points can occur between the releasable and the other rollers.

Der Einbau des Stützsegmentes erfolgt in umgekehrter Arbeitsweise durch Absetzen bzw. Einziehen des Querträgers 15 mit der Rolle 14 in die Tasche und nachfolgendes Einführen des Stützsegmentes über die Schienen 17. Da die Verbindungslöcher zwischen dem Querträger 15 und dem Stützsegment 8' vorgebohrt sind, sind Passungsarbeiten an der Anlage nicht mehr erforderlich. Statt Paßschrauben können auch andere formschlüssige Paß- und Verbindungsmittel verwendet werden.The installation of the support segment is carried out in the reverse way of working by placing or pulling the cross member 15 with the roller 14 into the pocket and then inserting the support segment over the rails 17. Since the connecting holes between the cross member 15 and the support segment 8 'are pre-drilled, fitting work is required no longer required on the system. Instead of fitting screws, other form-fitting fitting and connecting means can also be used.
