Description
Für die Signalgebung in Bergwerken in Blindschächten,. Förderbergen und in Förderstrecken «erden Schlagsignalgeber, sog. Schachthammer oder 1?inschlagwecker, benutzt, bei denen der Hammer mit Federkraft oder elektrischer Energie betätigt wird. Im folgenden wird eine Vorrichtung beschrieben, bei der die Betätigung des Hammers durch Druckluft über einen Druckluftkolben oder eine federnde Membran erfolgt.For signaling in mines in blind shafts. Mining mountains and in conveyor lines «earth impact signal generators, so-called shaft hammers or alarm clocks, used in which the hammer is operated with spring force or electrical energy will. The following describes a device in which the actuation of the Hammer is done by compressed air via a compressed air piston or a resilient membrane.
Die Erfindung wird an Hand der Abb. r und 2 näher erläutert. Die Vorrichtung besteht aus einem Luftventil i. das durch die Druckfeder 2 geschlossen wird. Beim Ziehen an dem Betätigungsseil 3 wird über den Kniehebel .I durch den Stößel 5 das Ventil i geöffnet. Die Luft strömt in das Steuergehäuse 6 und von da in den Zylinder 7 unter den Kolben 8 und treibt diesen mit dem Stößel 9 gegen den Hebel io. Durch den Federstahlbügel i i wird der Hammer 12 gegen den Ansatz 13 der Glockenschale geschlagen. Die Glockenschale 1.4 ist mit Schraube 15 und Scheibe 16 an dem mit Vierkant 17 versehenen Tragbolzen 18 befestigt, der auf der gemeinsamen Grundplatte i9 verschweißt ist.The invention is explained in more detail with reference to Figs. The device consists of an air valve i. which is closed by the compression spring 2. At the Pulling on the operating cable 3 is via the toggle lever .I through the plunger 5 the Valve i open. The air flows into the control housing 6 and from there into the cylinder 7 under the piston 8 and drives it with the plunger 9 against the lever io. By the spring steel bow i i is the hammer 12 against the approach 13 of the bell shell beaten. The bell shell 1.4 is with screw 15 and washer 16 on the Square 17 provided support bolt 18 attached to the common base plate i9 is welded.
ach Loslassen des Seilzuges 3 schließt sich das Ventil i wieder. Der Kolben 8 wird durch die an dem Hebel io angebrachte Rückholfeder 20 in die Ausgangsstellung gezogen. Die Vorrichtung ist zur Abgabe eines neuen Schlagsignals bereit.After releasing the cable 3, the valve i closes again. Of the Piston 8 is returned to its starting position by the return spring 20 attached to lever io drawn. The device is ready to emit a new impact signal.
Der Einfluß des Seilgewichtes des Seiles 3 wird bei unterschiedlicher Länge dadurch ausgeglichen, daß es in geringer oder weiterer Entfernung vom Drehpunkt des Ilebels 4 iii dafür vorgesehene Bohrungen angebracht «-ird.The influence of the rope weight of the rope 3 is different Length compensated by having it at a smaller or further distance from the pivot point des Ilebels 4 iii drilled holes provided for this purpose.
