Description
Vorrichtungen zum Antrieb von Apparaten, z. B. von elektrischen- Schaltern, die durch einen Elektromotor betätigt werden sollen, werden häufig auch mit einer Einrichtung versehen, durch die mau bei versagendem Motor den Schalter auch von Hand bedienen kann. Zu diesem Zweck wird mit der Schalterwelle, gegebenenfalls über ein Vorgelege, eine Welle gekuppelt, die mit einem AnsatzDevices for driving apparatus, e.g. B. of electrical switches through an electric motor to be operated, are often also with a device provided, through which the switch can also be operated by hand when the engine fails can. For this purpose, the switch shaft, if necessary via an intermediate gear, a shaft coupled to the one approach
ίο versehen ist, auf den ein Handrad oder eine Kurbel aufgesetzt werden kann. Um zu verhindern, daß bei aufgesetzter Kurbel der Antriebsmotor mit der Schalterwelle gekuppelt wird, oder daß bei gekuppeltem Motor die Kurbel aufgesetzt werden kann, wird eine Sperrvorrichtung angeordnet, die an Hand der Zeichnung beschrieben werden soll, α ist die Welle für den Handantrieb, die mit der nicht gezeichneten Schalterwelle fest gekuppelt und an ihrem Ende mit einem Vierkant b versehen ist, auf den eine Kurbel durch die Öffnung c in dem Gehäuse d aufgeschoben werden kann. Die Welle e dient zum Kuppeln und Entkuppeln des Antriebsmotors mit der Schalterwelle. In der gezeichneten Stellung, in der der Motor mit der Welle gekuppelt ist, wird vermittels der um den Punkt / drehbaren Stange g und der durch die Welle e bewegten Stange h ein Riegel i aus Blech vor die öffnung c geschoben, so daß die Kurbel durch diese Öffnung nicht eingeführt werden kann. Wird der Motor entkuppelt, so wird durch Drehen der Welle e das Gestänge und das Blech i in die gestrichelte Stellung bewegt und dadurch die öffnung c freigegeben. Außerdem muß bei aufgesetzter Kurbel ein Versuch, die Welle e in die Kuppelstellung zu bewegen, mißlingen, weil das Blech« gegen die Kurbel stößt und die Bewegung der Welle e in die Endstellung verhindert.ίο is provided on which a handwheel or a crank can be placed. In order to prevent the drive motor from being coupled to the switch shaft when the crank is attached, or that the crank can be attached when the motor is coupled, a locking device is arranged, which is to be described with reference to the drawing, α is the shaft for the manual drive, which is firmly coupled to the switch shaft, not shown, and is provided at its end with a square b , onto which a crank can be pushed through the opening c in the housing d. The shaft e is used to couple and uncouple the drive motor with the switch shaft. In the position shown, in which the motor is coupled to the shaft, a bolt i made of sheet metal is pushed in front of the opening c by means of the rod g which can be rotated around the point / and the rod h moved by the shaft e , so that the crank through this opening cannot be inserted. If the motor is decoupled, the rod and the plate i are moved into the position shown by the dashed line by rotating the shaft e, thereby releasing the opening c . In addition, when the crank is in place, an attempt to move the shaft e into the coupling position must fail because the sheet metal strikes the crank and prevents the shaft e from moving into the end position.
An Stelle der Kupplung zwischen Motor und Antrieb kann auch ein Schalter zum Einschalten des Motors treten. Weiterhin kann man auch gleichzeitig mechanische Kupplung und Motorschalter mit der Verriegelung des Kurbelangriffspunktes verbinden.Instead of the coupling between motor and drive, a switch can also be used to switch on of the engine. Furthermore, you can also lock the mechanical clutch and motor switch at the same time Connect the crank point of application.
