Description

Rollen 8 ein ringförmiger Teil 9, der Antriebsring, gelagert mit dessen Hilfe das Ausschwenken und Einschwenken der Tragarme 7 in horizontaler Ebene erfolgen.Rollers 8 an annular part 9, the drive ring, supported with the help of the pivoting and Swiveling the support arms 7 take place in the horizontal plane.

Zu diesem Zweck sind die Tragarme 7 mit ihr Lager umfassenden Zahnsegmenten 10 ausgestattet, die mit entsprechenden, im Antriebsring angeordneten Zahnkranzteilen 11 im Eingriff stehen. Der Antrieb des Rings erfolgt über ein weiteres, an der Innenweite d_s Rings vorgesehenes Zahnsegment 12, welches mit einem Zahnradvorgelege 13 im Eingriff steht Der Antrieb kann von Hand aus durchgeführt werden, wie in F i g. 3 dargestellt indem die Bewegung mittels eines abnehm baren Schlüssels 14 eingeleitet wird, oder der Antrieb kann motorisch erfolgen, wie in Verbindung mit F i g. 4 näher beschrieben wird. Mit 15 ist in Fig. 3 eine Verriegelungsvorrichtung angedeutet; diese kann z. B. oin Sperrad mit Klinke sein. For this purpose, the support arms 7 are equipped with toothed segments 10 comprising their bearings, which are in engagement with corresponding toothed ring parts 11 arranged in the drive ring. The ring is driven via a further toothed segment 12, provided on the inner width of the ring, which meshes with a gear train 13. The drive can be carried out by hand, as shown in FIG. 3 represented by the movement is initiated by means of a removable ble key 14 , or the drive can be motorized, as in connection with FIG. 4 will be described in more detail. A locking device is indicated at 15 in FIG. 3; this can e.g. B. be oin ratchet with pawl.

Bei der Ausführungsform nach F i g. 4 ist ein motorischer Antrieb vorgesehen; hierbei ist der Tragarm 7 mit einem Hebel 16 verbunden, an dem ein Schub-Zug-Gerät, z. B. die Kolbenstange eines hydraulischen Zylinders 17, angelenkt ist An Stelle des Hydraulikzylinders kann auch ein Elektromagnet verwendet werden.G in the embodiment of F i. 4 a motor drive is provided; here the support arm 7 is connected to a lever 16 on which a push-pull device, e.g. B. the piston rod of a hydraulic cylinder 17 is articulated. Instead of the hydraulic cylinder, an electromagnet can also be used.

Die Funktion der erfindungsgemäßen Vorrichtung ist die folgende: Je nach der Innenkontur der auszumauernden Tiegelzone werden durch Handantrieb oder motorischen Antrieb des Rings 9 die Tragarme 7 teilweise oder ganz ausgeschwenkt, wie in den Fig.2a und 2b erläutert. Das Ausscnwenken erfolgt im Gegenuhrzeigersinn, das Einschwenken im Uhrzeigersinn. Das Aus- bzw. Einschwenken aller Tragarme erfolgt gleichzeitig über den einzigen vorhandenen Antrieb, wodurch der Zeitaufwand wesentlich geringer ist als bei den einzelnen betätigten Klapparmen der bekannten Konstruktionen. Sobald die Tragarme ganz oder teilweise ausgeschwenkt sind, werden sie durch Füllplattformteile abgedeckt, wie in den F i g. 2a und 2b mit 18 und 19 angedeutet.The function of the device according to the invention is as follows: Depending on the inner contour of the crucible zone to be lined, the support arms 7 are partially or completely swiveled out by hand drive or motor drive of the ring 9, as explained in FIGS. 2a and 2b. Swiveling out is counterclockwise, swiveling in clockwise. All support arms are swiveled out and in at the same time via the only existing drive, which means that the time required is significantly less than with the individually actuated folding arms of the known constructions. As soon as the support arms are fully or partially swung out, they are covered by filling platform parts, as shown in FIGS. 2a and 2b indicated by 18 and 19.

Die erfindungsgemäße Einrichtung bedarf nur geringer Wartung, da ihr Amneb geschützt unter dem zentralen Plattformteil 5 liirgt: sie zeichnet sich durch eine >:ute Handlichkeit und hohe Betriebssicherheii aus.The device according to the invention requires little maintenance, since its Amneb is protected under the central platform part 5 lies: it is characterized by >: ute handiness and high operational reliability.
