Description
Sicherheitsvorrichtung für die Befestigung von Röstofenarmen mit Bajonettverschluß Die bekannten Ausführungen der Röstofenarme mit Bajonettverschluß haben gegenüber den Bauarten, bei denen die- Befestigung durch Schrauben, Keile usw. erfolgt, den Vorteil, däß sie leichter während- kurzer Betriebspausen, also auch bei heißem Ofen, ausgebaut werden können. Es bleibt dabei aber immer noch die Schwierigkeit, die Arme gegen Verdrehung um ihre eigene Achse zu sichern.Safety device for attaching roasting oven arms with bayonet lock The known versions of the roasting oven arms with bayonet lock have opposite the types in which the fastening is carried out by screws, wedges, etc., the Advantage that they are easier to use during short breaks in operation, i.e. even when the oven is hot, can be expanded. But there still remains the difficulty that To secure arms against twisting around their own axis.
Die vorliegende Erfindung schafft- eine einfache und bequem zu handhabende Vorrichtung, durch welche dieser Übelstand beseitigt wird. Sie besteht darin, daß an dem Rostofenarm ein Riegel.a verschieblich und drehbar so gelagert ist, daß er in seiner einen Endstellung in eine Vertiefung e der. Rührwelle hineinragt, wobei er durch einen am. Röstofenarm befestigten Knaggen c- gehalten, und daß er zwecks Lösung der Verbindung durch eine Drehung außer Eingriff mit dem Knaggen gebracht und zurückgezogen wird. b Man kann diese Sicherheitsvorrichtung sehr leicht von einer Ofentür aus bedienen, und da= durch, daß sie an dem luftgekühlten Rührarm befestigt ist, wird sie stets genügend gekühlt und vor Verbrennen gesichert.The present invention provides a simple and convenient one to use Device by which this deficiency is eliminated. It consists in that on the grate furnace arm a Riegel.a is slidably and rotatably mounted so that it in its one end position in a recess e the. Stirrer shaft protrudes, wherein it is held by a catch attached to the roaster arm, and that it is for the purpose of Release of the connection brought out of engagement with the lug by a rotation and is withdrawn. b This safety device can be removed very easily from an oven door, and there = by that they on the air-cooled agitator arm is attached, it is always sufficiently cooled and protected from burning.
Es sind zwar auch Befestigungsarten von Röstofenarmen bekannt, bei denen die Rührarme entgegen der Drehrichtung der Königswelle eingeschoben und durch besondere Keile auch gegen ein zufälliges Lösen gesichert sind. Diese Keile können jedoch weder bei heißem Ofen noch von außen gelöst werden, so daß ein Ausbauen solcher Rührarme in kurzen Betriebspausen ebenfalls nicht möglich ist.There are also known types of attachment of roasting oven arms which the agitator arms are pushed in and through against the direction of rotation of the vertical shaft special wedges are also secured against accidental loosening. These wedges can However, neither when the furnace is hot nor from the outside, so that such a dismantling Mixing arms in short breaks in operation is also not possible.
-Die Zeichnung gibt ein Ausführungsbeispiel wieder, und zwar in Abb. i in Ansicht: Abb. a ist ein teilweiser Schnitt nach der-Linie A-B -und Abb. 3 eine Ansicht in Pfeilrichtung C.-The drawing shows an embodiment, namely in Fig. i in view: Fig. a is a partial section along the line A-B and Fig. 3 is a View in the direction of the arrow C.
Wie die Zeichnung erkennen- läßt, ist an dem Rührarm f ein Vorsprung d angebracht, in welchem ein winklig gebogener Riegel a gleiten kann. Ferner ist an dem Rührarm ein Knaggen c befestigt. Wenn der Rührarm mittels des Bajonettverschlusses richtig in die Rührwelle g eingeführt ist, schiebt man den Riegel a aus der - strichpunktiert gezeichneten Stellung -vor und dreht ihn gleichzeitig um i8o°. Dadurch gelangt das vordere Ende des Riegels in, die Ausnehmung e der Rührwelle, so daß der Rührarm gegen Verdrehung gesichert ist. Das hintere Ende -b des Riegels liegt aber dann vor dem Knaggen c, so daß die Sicherung sich nicht zufällig lösen kann. Wenn- man den Rührarm aus der Rührwelle herausnehmen will, so dreht man den Riegel ä um 18o' nach oben, so daß er nicht mehr durch den Knaggen c behindert ist, und zieht ihn so weit zurück, daß er nicht mehr in Eingriff mit der Rührwelle steht.As the drawing shows, there is a projection on the agitator arm f d attached, in which an angled bolt a can slide. Furthermore is a catch c is attached to the agitator arm. When the agitator arm by means of the bayonet lock is correctly inserted into the agitator shaft g, one pushes the bolt a out of the - dash-dotted line position drawn in front of it and at the same time rotates it by 180 °. This is how the front end of the bolt in, the recess e of the agitator shaft, so that the agitator arm is secured against rotation. The rear end -b of the bolt is then in front of the collar c, so that the fuse cannot accidentally come loose. If want to remove the agitator arm from the agitator shaft, turn the bolt ä by 18o ' upwards, so that it is no longer obstructed by the collar c, and pulls it so far back that it is no longer in engagement with the agitator shaft.
