Bei all denjenigen Fangvorrichtungen, die mit Druckgas betrieben werden, wird man damit rechnen müssen, daß der Gasdruck durch Undichtigkeiten der Leitungen und Ventile so weit herabsinken kann, daß die durch denselben gebremst gehaltenen Fördereinrichtungen ihren Fall fortsetzen.With all those safety gears that are operated with compressed gas, one will Have to expect that the gas pressure can drop so far through leaks in the lines and valves that the continue their fall by the same braked conveyors.
Bei der durch Patent 193848 geschützten Bremseinrichtung tritt ein solches Weiterstürzen des Fahrkorbes z. B. ein, wenn der Gasdruck auf 10 Atmosphären heruntergesunken ist. Um auch in diesen Fällen ein sicheres Festhalten des gebremsten Fahrkorbes zu ermöglichen, erscheint es zweckmäßig, neben der gewöhnlichen Bremseinrichtung noch eine selbsttätige Befestigung der Förderschale für den Fall des Herabsinkens des Gasdruckes auf vielleicht 20 Atmosphären einzuführen. Dies soll durch die in den Fig. 1, 2 und 3 dargestellte Vorrichtung erreicht werden. When protected by patent 193848 Braking device occurs such a further falling of the car z. B. a, if the Gas pressure has dropped to 10 atmospheres. To even in these cases one To enable the braked car to be held securely, it appears expedient to In addition to the usual braking device, there is also an automatic attachment of the conveyor bowl in case the gas pressure drops to perhaps 20 atmospheres. This is to be achieved by the device shown in FIGS. 1, 2 and 3.
Von einem im Fahrkorb befindlichen Druckgasbehälter aus wird der Kolben a, der in seiner Verlängerung das Ventil b schließt, durch ständigen Druck gegen die Feder g gepreßt. Diese Feder ist erst dann stark genug, den Kolben α zu heben und das Ventil δ zu öffnen, wenn der Druck über dem Kolben α sich durch Undichtigkeiten usw. auf 20 Atmosphären vermindert hat. The piston a, which closes the valve b in its extension, is pressed by constant pressure against the spring g from a pressurized gas container located in the car. This spring is only strong enough to lift the piston α and open the valve δ when the pressure above the piston α has decreased to 20 atmospheres due to leaks etc.
Durch das geöffnete Ventil b gelangt dann durch eine besondere Zuleitung das Druckgas in einen Zylinder unter den Kolben d, der im Vorrücken eine Rolle oder einen Keil β zwischen die Führungsschienen der Schale und diejenigen des Schachtes preßt und damit die Schale dauernd feststellt.The compressed gas then passes through the open valve b through a special feed line into a cylinder under the piston d, which presses a roller or a wedge β between the guide rails of the shell and those of the shaft and thus permanently fixes the shell.
