Bei gewissen Arten von Druckluftschaltern, z. B. Schaltern ohne schnellwirkende Reihentrennschalter, ist es wünschenswert, nach einem Schaltvorgang den beweglichen Kontakt des Schalters in offener Lage halten zu können. Die Erfindung betrifft einen hierfür geeigneten Schaltmechanismus für einen solchen Druckluftschalter und ist dadurch gekennzeichnet, daß die Haltekraft der Greifanordnung vom Druck der Betätigungsluft abhängt und mit steigendem Betätigungsluftdruck zunimmt.With certain types of compressed air switches, e.g. B. switches without quick-acting series disconnectors, it is desirable to keep the movable contact of the switch in the open position after a switching operation to be able to hold. The invention relates to a switching mechanism suitable for this purpose Compressed air switch and is characterized in that the holding force of the gripping arrangement from pressure depends on the actuating air and increases with increasing actuating air pressure.
Es ist bekannt, den beweglichen Kontakt in offener Lage zu verriegeln. Eine solche Verriegelung wird in manchen Fällen als Greifvorrichtung bezeichnet. Demgegenüber bringt die Erfindung eine beträchtliche Vereinfachung, da die Abhängigkeit der Haltekraft von dem Druck der Betätigungsluft bewirkt, daß bei abgeschalteter Betätigungsluft die Greifanordnung nahezu unwirksam wird. Man braucht daher zum Betätigen für den Kontakt und für die Verriegelungsanordnung nur eine einzige Betätigungsluftanordnung. It is known to lock the movable contact in the open position. Such a lock is in sometimes referred to as a gripping device. In contrast, the invention brings a considerable Simplification, since the dependency of the holding force on the pressure of the actuating air causes that when the actuating air is switched off, the gripping arrangement is almost ineffective. You need therefore only a single actuating air arrangement for actuation for the contact and for the locking arrangement.
Die Greifanordnung wird von der Betätigungsluft über einen Kolben und ein Hebelsystem betätigt, und der bewegliche Kontakt ist mit einer Stange verbunden, deren freies Ende mit einem Absatz oder einer Ausnehmung für die Greifanordnung versehen ist. Die Greifanordnung selbst besteht vorteilhaft aus zwei parallelen Rollen, die im wesentlichen winkelrecht zu der Bewegungsrichtung der Kontaktstange angeordnet sind. Die Rollen legen sich in der offenen Lage des beweglichen Kontaktes gegen die Kontaktstange und werden dabei, wenn der Betätigungsluftdruck auf den Kolben der Greifanordnung einwirkt, mit solcher Kraft gegen die Stange gedrückt, daß der bewegliche Kontakt in offener Lage gehalten wird.The gripping arrangement is actuated by the actuating air via a piston and a lever system, and the movable contact is connected to a rod, the free end of which with a shoulder or a recess is provided for the gripping arrangement. The gripping arrangement itself advantageously consists of two parallel rollers which are substantially perpendicular to the direction of movement of the contact rod are arranged. In the open position of the movable contact, the rollers lie against the contact rod and when the actuating air pressure acts on the piston of the gripper assembly, pressed against the rod with such force that the movable contact is held in the open position.
Die Erfindung hat gegenüber bekannten Konstruktionen vor allem den Vorteil, daß ein zum Schaltmechanismus gehörendes Blasventil von derselben Betätigungsluft betätigt werden kann wie der bewegliche Kontakt, ohne daß zusätzliche Steuerventile oder Leitungen erforderlich sind.The invention has the main advantage over known constructions that a switching mechanism belonging blow valve can be actuated by the same actuating air as the movable one Contact without the need for additional control valves or lines.
Eine Ausführungsform der Erfindung ist an Hand des im folgenden beschriebenen Schalters angegeben. In der Zeichnung, die den Schaltmechanismus in geschlossener Lage zeigt, bezeichnet 1 einen Teil eines Druckluftbehälters. In seiner Wand ist ein Gehäuse 2 für den beweglichen düsenförmigen Kontakt 3 angeordnet. 4 ist ein fester Kontakt, der von einer in der Wand des Behälters 1 angeordneten, in der Zeichnung nicht gezeigten Durchführung getragen wird. Der Behälter kann durch die Düse im beweglichen Kontakt 3 und ein Blasventil 5 über Kanäle 6 mit der Schaltmechanismus für DruckluftschalterAn embodiment of the invention is given with reference to the switch described below. In the drawing showing the switching mechanism in the closed position, 1 denotes part of a Compressed air tank. A housing 2 for the movable nozzle-shaped contact 3 is arranged in its wall. FIG. 4 is a fixed contact that is made by one disposed in the wall of the container 1 in the drawing implementation not shown is worn. The container can be moved through the nozzle Contact 3 and a blow valve 5 via channels 6 with the switching mechanism for compressed air switches

freien Luft in Verbindung gesetzt werden. Das Blasventil 5 ist mit einem Kolben 7 verbunden, auf dessen einer Seite ein Raum 8 über eine Betätigungsluftleitung 9 mit einem Druckluftbehälter oder mit der freien Luft in Verbindung gesetzt werden kann. Der Raum 10 auf der Rückseite des Kolbens 7 steht durch einen Kanal 11 ständig in Verbindung mit dem Raum 8. Eine Feder 12 drückt den beweglichen Kontakt 3 gegen den festen Kontakt 4, und eine Feder 13 hält das Blasventil geschlossen.free air. The blow valve 5 is connected to a piston 7, on one side of which a space 8 can be connected to a compressed air tank or to the free air via an actuating air line 9. The space 10 on the back of the piston 7 is constantly in communication with the space 8 through a channel 11. A spring 12 presses the movable contact 3 against the fixed contact 4, and a spring 13 keeps the blow valve closed.
Im Raum 8 sind zwei Greif arme 14 auf den am Gehäuse 2 befestigten Bolzen 15 schwenkbar angeordnet. An der Spitze jedes Greifarmes 14 ist eine Rolle 16 befestigt. Der Kolben 17 betätigt die Greifarme über ihre Ansätze 18. Zwischen jedem Ansatz 18 und dem Kolben 17 ist eine Feder 19 angeordnet. Der bewegliche Kontakt ist mit einer Stange 20 verbunden, die am unteren Ende verjüngt ist, um leichter zwischen die Rollen 16 der Greifarme gepreßt werden zu können. Die Stange 20 ist mit einer Ausnehmung 21 versehen.In space 8, two gripping arms 14 are pivotably arranged on the bolts 15 attached to the housing 2. A roller 16 is attached to the tip of each gripping arm 14. The piston 17 actuates the gripping arms via their lugs 18. Between each lug 18 and the piston 17, a spring 19 is arranged. The moving contact is connected to a rod 20, which is tapered at the lower end to more easily pressed between the rollers 16 of the gripping arms to be able to. The rod 20 is provided with a recess 21.
Der Schalter wird dadurch geöffnet, daß der Raum 8 mit Druckluft gefüllt wird. Dabei wird das Blasventil 5 geöffnet, und die Druckluft im Behälter 1 strömt durch den beweglichen Kontakt 3 und die Kanäle 6 hinaus. Wegen der dabei entstehenden Drucksenkung unter dem beweglichen Kontakt wird dieser vom Druck im Behälter 1 nach unten geführt und trifft dabei auf den Ventilkopf des Blasventils 5, der, nachdem der Luftdruck zwischen den Räumen 8 und 10 ausgeglichen worden ist, von dem beweglichen Kontakt in geschlossene Lage getrieben wird.The switch is opened in that the space 8 is filled with compressed air. The blow valve 5 is opened and the compressed air in the container 1 flows out through the movable contact 3 and the channels 6. Because of the resulting pressure drop under the movable contact, it is guided downward by the pressure in the container 1 and hits the valve head of the blow valve 5, which, after the air pressure between the spaces 8 and 10 has been equalized, from the movable contact to closed Location is driven.

In dieser Lage sind die Rollen 16 in die Ausnehmung 21 hinuntergefallen und werden nun vom Luftdruck, der auf den Kolben 17 einwirkt, gegeneinandergepreßt. Der Kontakt 3 wird in dieser Weise in seiner offenen Lage gehalten. Sobald der Raum 8 in Verbindung mit der freien Luft gesetzt wird und der Druck in diesem Raum unter einen gewissen Wert gesunken ist, werden die Rollen 16 getrennt, wenn die schräggestellten Wände der Ausnehmung 21 mittels der Feder 12 des beweglichen Kontaktes aufwärts gegen die Rollen gepreßt werden, die nun genügend Kraft hat, den Schalter zu schließen.In this position, the rollers 16 have fallen down into the recess 21 and are now from the air pressure, which acts on the piston 17, pressed against each other. The contact 3 is in this way in his kept open. As soon as the space 8 is put in connection with the open air and the Pressure in this space has fallen below a certain value, the rollers 16 are separated when the inclined walls of the recess 21 by means of the spring 12 of the movable contact upwards pressed against the rollers, which now has enough force to close the switch.
