Description
Fangvorrichtung für Eimerketten. Die Erfindung bezweckt, die Fangvorrichtung nach dem Hauptpatent derart weiter auszubilden, daß sie auch den Antriebmotor der Eimerkette ausschaltet, sobald sie durch die gerissene Kette belastet wird. Zu diesem Zweck sind die beweglich gelagerten Fangarme mit einem Sehalter verbunden, der bei der durch die Belastung der Fangarme bei Kettenbruch erfolgenden Bewegung im Sinne einer Ausschaltung des Antriebmotors betätigt wird. Vor anderen Ausschaltungsvorrichtungen zeichnet sich die Erfindung dadurch aus, daß die Ausschaltevorrichtung keine beweglichen Teile besitzt, die im laufenden Betriebe die Kette berühren. Infolgedessen werden die unerwünschten zufälligen Ausschaltungen des Antriebmotors vermieden, die bei anderen Ausschaltvorrichtungen auch in solchen Fällen erfolgen können, wo die Kette nicht gerissen ist oder gefangen wird.Safety catch for bucket chains. The aim of the invention is the safety gear to train according to the main patent so that they also the drive motor of the Bucket chain switches off as soon as it is loaded by the broken chain. To this Purpose, the movably mounted tentacles are connected to a Sehalter, which at the movement caused by the load on the tentacles in the event of chain breakage a shutdown of the drive motor is operated. Before other shutdown devices The invention is characterized in that the disconnection device is not movable Owns parts that touch the chain during operation. As a result will be the undesired accidental shutdowns of the drive motor avoided with other disconnection devices can also be made in cases where the chain is not cracked or caught.
Die Zeichnung zeigt zwei Ausführungsbeispiele der Erfindung -in schematischer Darstellung. Abb. i zeigt eine Vorrichtung mit unmittelbarer Verbindung eines Kontaktes mit den Fangarmen, Abb. 2 mit Verbindung durch Übersetzungshebel. Die Fangarme a der Fangvorrichtung sind am Gestell des Baggers b schwingend gelagert; ein bei c am Baggergestell befestigter Bolzen d begrenzt die Bewegung der Fanghebel unter Zwischenschaltung von Spiralfedern e. An den Fanghebeln ist eine Feder angebracht, die im laufenden Betriebe einen Kontakt i berührt. Durch die Feder und den Kontakt ist der Strom des Motörs oder eines Ruhestromrelais für einen Motorausschalter geführt. Bewegen sich bei Kettenbruch unter der Last des abstürzenden Kettentrums die Fangarme, so wird der Kontakt bei i unterbrochen und dadurch der Motorstrom ausgeschaltet. Die Einrichtung nach Abb. 2 unterscheidet sich von der nach Abb. i nur dadurch, daß zwischen den Kontakt i und die Fangvorrichtung noch ein Übersetzungshebel k eingeschaltet ist.The drawing shows two exemplary embodiments of the invention in schematic form Depiction. Fig. I shows a device with a direct connection of a contact with the tentacles, Fig. 2 with connection through transmission lever. The tentacles a the safety gear are swingably mounted on the frame of the excavator b; a at c Bolt d attached to the excavator frame limits the movement of the catch lever Interposition of spiral springs e. A spring is attached to the catch levers, which touches a contact i during operation. By the spring and the contact the current of the motor or a closed-circuit relay for a motor cut-off switch is conducted. If the chain breaks, the tentacles move under the load of the falling chain strand, so the contact at i is interrupted and the motor current is switched off. The device according to Fig. 2 differs from that according to Fig. I only in that that between the contact i and the safety gear still a transmission lever k is switched on.
