Description

Vorrichtung zum Einspannen feuerfester Platten in metallische Rahmen von Schieberverschi üssen Device for clamping refractory plates in metal frames of slide closures
B e s c h r e i b u n gDescription
Die Erfindung bezieht sich auf eine Vorrichtung zum Einspannen von feuerfesten Platten in metallische Rahmen von SchieberverschlUssen für den Ausguß metallurgischer Gefäße, mit einem Keil stück, das durch Verstellen mittels eines im Rahmen angeordneten Gewindebolzens Keilwirkung über eine schräg zum Plattenumfang geneigte Treibfläche ausübt.The invention relates to a device for clamping refractory plates in metallic frames of slide closures for the pouring of metallurgical vessels, with a wedge piece that exerts wedge action by adjusting by means of a threaded bolt arranged in the frame over a driving surface inclined to the plate circumference.
Aus der DE-OS 35 22 134 sind Spannvorrichtungen mit Keilstücken bekannt, die zwischen der Umfangsf l che der feuerfesten Platte und einem Umfangsboard des metallischen Rahmens zur Wirkung kommen, indem durch Löcher der Keilstücke gesteckte und in Gewindebohrungen des Rahmens eingeschraubte Gewindebolzen festgezogen werden. Nachteilig ist dabei, daß beim Lösen der Gewindebolzen, beispielsweise zum Plattenaustausch, die Keilstücke infolge von Wärmeverspannungen und Verschmutzungen oftmals festklemmen und aus ihrer Position nur mühsam entfernt werden können, was einem zügigen Auswechseln der Platten hinderlich ist. Die mit vorliegender Erfindung zu lösende Aufgabe besteht in einer Verbesserung der Wirkungsweise der Spannvorrichtung, insbesondere beim Lösen der Verspannung.From DE-OS 35 22 134 clamping devices with wedge pieces are known, which come into effect between the peripheral surface of the refractory plate and a peripheral board of the metallic frame, by inserting threaded bolts through holes in the wedge pieces and screwing them into threaded holes in the frame. The disadvantage here is that when loosening the threaded bolts, for example for plate replacement, the wedge pieces often jam due to thermal stresses and soiling and can only be removed with difficulty from their position, which is an obstacle to rapid replacement of the plates. The object to be achieved with the present invention is to improve the mode of operation of the tensioning device, in particular when releasing the tension.
Die gestellte Aufgabe wird gemäß der Erfindung im wesentlichen dadurch gelöst, daß das Keilstück auf dem Gewinde eines im Rahmen verdrehbar gelagerten Gewindebolzens bewegl ch ist und mit seiner Treibfläche auf die Druckfläche einer im Rahmen gleitenden Spannbacke wirkt, die mit dem Keilstück über entsprechend der Treibfläche geneigte Führungsbahnen in Eingriff steht. Auf diese Weise wird beim Anziehen des Gewindebolzens nicht nur ein gleichmäßig einspannender Flächendruck über die Spannbacke auf die Plattenumfangsflache übertragen, die in jedem Fall lotrecht zur Plattenebene steht, sondern beim Aufdrehen des Gewindebolzens mit dem Lösen des KeilStückes gleichzeitig ein Zurückfahren der Spannbacke vom Plattenumfang erreicht. Dadurch wird die feuerfeste Platte für einen unbehinderten schnellen Plattenwechsel im Rahmen automatisch offengelegt.The object is achieved according to the invention essentially in that the wedge piece on the thread of a rotatably mounted threaded bolt in the frame is movable and acts with its driving surface on the pressure surface of a sliding jaw which slides in the frame and inclined with the wedge piece over the driving surface Guideways engaged. In this way, when tightening the threaded bolt, not only is a uniformly clamping surface pressure transferred to the circumferential surface of the plate via the clamping jaw, which is in any case perpendicular to the plane of the plate, but when the threaded bolt is unscrewed, the clamping jaw is simultaneously retracted from the circumference of the plate. As a result, the fireproof plate is automatically exposed in the frame for an unimpeded quick plate change.
Im einzelnen wird bezüglich des Aufbaues der Vorrichtung zweckmäßig so vorgegangen, daß die Spannbacke in einem Bett des Rahmens gleitet und dabei das auf dem Gewindebolzen bewegliche Keilstück U-förmig mit in Gleitrichtung liegende Längsseiten umfaßt, in derem Berührungsbereich die Führungsbahnen liegen. Diese sind vorteilhaft als an der Druckfläche der Spannbacke in den Längsseiten angeordnete Nuten und gegenprofilierte Federn des KeilStückes ausgebildet. Eine solche Konstruktion ist einfach und wirkungsvoll.In detail, with regard to the structure of the device, the procedure is expediently such that the clamping jaw slides in a bed of the frame and thereby comprises the U-shaped wedge piece which is movable on the threaded bolt and has longitudinal sides lying in the sliding direction, in whose contact area the guideways lie. These are advantageously designed as grooves arranged on the pressure surface of the clamping jaw in the longitudinal sides and counter-profiled springs of the wedge piece. Such a construction is simple and effective.
Bezüglich der Ausbildung, Anordnung und Handhabung des das Keilstück tragenden Gewindebolzens schlägt die Erfindung vor, daß der Bolzen lotrecht oder nahezu lotrecht zur Plattenebene angeordnet ist und mit einem Bund in einer abgesetzten Ausnehmung des Rahmens lagert und ein Steckschiüsselprofil in dem zur Montagefläche des Rahmens zeigenden Gewindeteil hat. Dadurch ergibt sich eine kompakte Bauweise der Vorrichtung, die verspannt vollständig im Rahmen integriert ist. Die Erfindung ist nachstehend anhand der Zeichnung an einem Ausführungsbeispiel erläutert. Es zeigen:With regard to the design, arrangement and handling of the threaded bolt carrying the wedge piece, the invention proposes that the bolt be arranged perpendicular or almost perpendicular to the plane of the plate and supported with a collar in a recessed recess in the frame and a socket profile in the threaded part pointing towards the mounting surface of the frame Has. This results in a compact construction of the device, which is fully integrated under tension in the frame. The invention is explained below with reference to the drawing using an exemplary embodiment. Show it:

Figur 5 einen Querschnitt des Teils 8 nach Figur 4,FIG. 5 shows a cross section of part 8 according to FIG. 4,
Figur 6 eine Draufsicht auf den Teil 18 nach Figur 3, undFigure 6 is a plan view of part 18 of Figure 3, and
Figur 7 eine Seitenansicht des Teils 18 nach Figur-6.Figure 7 is a side view of part 18 of Figure 6.
Der im einzelnen nicht näher beschriebene Schieberverschluß 1 nach Figur 1 hat zwei feuerfeste Verschlußplatten 2, eine ortsfeste Bodenplatte und eine verstellbare Schieberplatte. Beide sind in metallischen Rahmen 3 gehalten. Die Bodenplatte im Gehäuserahmen 4 und die Schieberplatte im Schieberrahmen 5, der in einer über die Schließstellung hinausgefahrenen Position um die Achse 6 aus der Betriebsstellung nach unten herausgeschwenkt werden kann. In dieser in Figur 1 der Einfachheit halber nicht gezeigten Stellung des Schieberrahmens 5 sind die identischen Spannvorrichtungen 7 zugänglich, mit denen die Platten 2 in ihren Rahmen 3 eingespannt sind, um Relativbewegungen zwischen der Platte 2 und dem Rahmen 3 beim Verstellen des Schieberrahmens 5 zu vermeiden. Weitere Vorrichtungen können zum Einspannen der ortsfesten Unterplatte an Dreiplatten- Schieberverschlüssen vorgesehen sein. Jede Vorrichtung 7 hat eine U-förmig ausgebildete Spannbacke 8, die mit an den U-Schenkeln vorgesehenen Flankenleisten 9 in einem Gleitbett 10 des Rahmens 3 geführt ist. Die äußere Seite des die Schenkel verbindenden U-Steges dient als Kontaktseite 11 gegenüber dem Plattenumfang 14, und zwar über einen darauf aufgezogenen Blechreifen 13. Parallel zur Kontaktseite 11 ist an der Innenseite des U-Steges eine schräg zum Plattenumfang 14 geneigte Druckfläche 15 vorgesehen, deren Enden in an den Innenseiten 16 der U-Schenkel mit derselben Schräglage angeordneten Nuten 17 hineinverlängert sind (Figuren 4 und 5),The slide closure 1 according to FIG. 1, which is not described in detail, has two fire-resistant closure plates 2, a stationary base plate and an adjustable slide plate. Both are held in metallic frames 3. The base plate in the housing frame 4 and the slide plate in the slide frame 5, which can be pivoted out about the axis 6 from the operating position in a position moved beyond the closed position. In this position of the slide frame 5, which is not shown in FIG. 1 for the sake of simplicity, the identical clamping devices 7 are accessible with which the plates 2 are clamped in their frame 3 in order to avoid relative movements between the plate 2 and the frame 3 when the slide frame 5 is adjusted . Further devices can be provided for clamping the fixed lower plate on three-plate slide closures. Each device 7 has a U-shaped clamping jaw 8 which is guided in a sliding bed 10 of the frame 3 with flank strips 9 provided on the U-legs. The outer side of the U-web connecting the legs serves as a contact side 11 with respect to the plate circumference 14, specifically by means of a sheet metal tire 13 mounted thereon. the ends of which are extended into grooves 17 arranged on the inner sides 16 of the U-legs with the same inclined position (FIGS. 4 and 5),
Die U-förmige Spannbacke 8 umfaßt ein Keilstück 18, das mit Federn 19 in die Nuten 17 greift und dessen Treibfläche 20 die Gegenfläche zur Druckfläche 15 bildet. Umgekehrt könnte auch mindestens eine Feder in der Spannbacke 8 ausgebildet sein, die in entsprechender Weise in Eingriff mit einer im Keilstück 18 ausgebildeten Nut stehen würde. Dabei ist das mit einer Gewindebohrung 21 versehene Keilstück 18 vertikal zur Planebene von Platte 2 und Rahmen 3 verstellbar auf einem in einer abgesetzten Bohrung 22 des Rahmens 3 um die Längsachse verdrehbar lagernden Gewindebolzen 23 angeordnet. Dieser hintergreift mit einem Bund 24 einen Absatz 25 der die Rahmendicke durchstechenden Bohrung 22 und trägt in seiner gewindeseitigen Stirnfläche 26 ein Profil 24 zum Einführen eines Steckschlüssels 28. Der am Absatz 25 erweiterte Teil 29 der Rahmenbohrung 22 ist die Einführseite des Bolzens 23 und durch einen Stopfen 30 verschließbar. Im übrigen grenzt das Keilstück 18 mit seinem von der Spannbacke 7 nicht umfaßten, abgerundeten Umfangsbereich 30 an die das Gleitbett 10 im Rahmen 3 beendende Querwand 32 an.The U-shaped clamping jaw 8 comprises a wedge piece 18 which engages in the grooves 17 with springs 19 and whose driving surface 20 forms the counter surface to the pressure surface 15. Conversely, at least one spring could also be formed in the clamping jaw 8, which would be in a corresponding manner in engagement with a groove formed in the wedge piece 18. The wedge piece 18, which is provided with a threaded bore 21, is adjustable vertically to the plane of the plate 2 and frame 3 and is arranged on a threaded bolt 23 which is rotatable about the longitudinal axis in a stepped bore 22 of the frame 3. This engages with a collar 24 a shoulder 25 of the bore 22 piercing the frame thickness and carries in its thread-side end face 26 a profile 24 for inserting a socket wrench 28. The part 29 of the frame bore 22, which is extended on the shoulder 25, is the insertion side of the bolt 23 and through a Stopper 30 closable. For the rest, the wedge piece 18 borders with its rounded peripheral region 30, which is not encompassed by the clamping jaw 7, against the transverse wall 32 which ends the sliding bed 10 in the frame 3.
Wie insbesondere aus Figur 3 ersichtl ch, fährt beim Hantieren des Schlüssels 28 zum Festspannen der Platte 2 im Rahmen 3 das Keilstück 18 in den Gewindebolzen 23 hinein und bewegt die Spannbacke 8 durch Druckgebung über die Treibfläche 20 und die Druckfläche 15 im Gleitbett 10 in Richtung des Plattenumfanges 14, bis der Einspanneffekt erreicht ist. Umgekehrt schieben beim Lösen der Einspannung durch Herausfahren des KeilStückes 18 aus dem Gewindebolzen 23 die in den Führungsbahnen 17 gleitenden Federn 19 die Spannbacke 8 vom Plattenumfang 14 weg und geben somit die P atte 2 zur Handhabung frei .As can be seen in particular in FIG. 3, when the key 28 for clamping the plate 2 in the frame 3 is being manipulated, the wedge piece 18 moves into the threaded bolt 23 and moves the clamping jaw 8 in the direction of pressure by means of the driving surface 20 and the pressure surface 15 in the sliding bed 10 of the plate circumference 14 until the clamping effect is reached. Conversely push when loosening the Clamping by moving the wedge piece 18 out of the threaded bolt 23, the springs 19 sliding in the guideways 17, the clamping jaw 8 away from the plate circumference 14 and thus releasing the plate 2 for handling.
Es liegt im Wesen der Erfindung, die Vorrichtung 7 an anderen Umfangsbereichen der Platte 2 al s des gezeigten stirnseitigen Bereiches einzusetzen. Ferner können mehrere Vorrichtungen 7 über den Plattenumfang 14 verteilt vorgesehen sein, der im Zusammenwirken mit der K&ntaktflache 11 der Spannbacke 8 beispielsweise auch ovale oder runde Gestalt haben kann.It is in the essence of the invention to use the device 7 on other peripheral regions of the plate 2 as the end region shown. Furthermore, a plurality of devices 7 can be provided distributed over the plate circumference 14, which in cooperation with the contact surface 11 of the clamping jaw 8 can also have an oval or round shape, for example.
Ferner könnte der Gewindebolzen statt lotrecht, ebensogut parallel zur Plattenebene und zu deren Umfang im Rahmen 3 gelagert sein; die Treib-und die Druckfläche müßten dann in horizontaler Richtung schräg sein, und in entsprechender Weise zum Ausführungsbeispiel würde eine an der Treibfläche ausgebildete Mitnehmerfeder mit einer in der Spannbacke vorgesehenen Nut in Eingriff stehen. Furthermore, the threaded bolt could be mounted parallel to the plane of the plate and its circumference in the frame 3 instead of perpendicular; the drive and pressure surfaces would then have to be oblique in the horizontal direction, and in a corresponding manner to the exemplary embodiment, a driver spring formed on the drive surface would engage with a groove provided in the clamping jaw.
