Description
Grubenstempel Gegenstand der Erfindung ist ein Grubenstempel mit rohrförmigem Außenstempel, dessen Hohlraum durch ein von Hand zu öffnendes Ventil in zwei Kammern unterteilt ist, wobei in einer dieser Kammern der Innenstempel geführt'wird, der nach dem Setzen des Grubenstempels bei geschlossenem Ventil auf einem Füllmittel aufruht. Derartige Grubenstempel sind bekannt. Anderseits ist es nicht neu, zum Setzen des Stempels eine Flüssigkeit als Füllmittel durch Preßluft aus einer Kammer des Innenstempels, die durch ein abhebbares Ventil verschließbar ist, in den Hohlraum des Außenstempels zu pressen und damit die Stempelteile auseinanderzuscHeben. Bei diesem Stempel ist hierbei zwischen der Flüssigkeit, die sich im Außenstempel befindet, .und dem als Kolben ausgebildeten Ende des Innenstempels ein Luftkissen vorgesehen.Pit punch The subject of the invention is a pit punch with a tubular Outer stamp, the cavity of which is divided into two chambers by a valve that can be opened by hand is subdivided, the inner stamp being guided in one of these chambers, the after setting the pit punch with the valve closed on a filler rests. Such pit punches are known. On the other hand, it's not new to the Setting the stamp a liquid as a filler by compressed air from a chamber of the inner die, which can be closed by a valve that can be lifted off, into the cavity to press the outer punch and thus lift the punch parts apart. at this stamp is between the liquid that is in the outer stamp, .And the end of the inner plunger designed as a piston is provided with an air cushion.
Nach der Erfindung befindet sich in der Kammer, in die der Innenstempel nicht eintritt, ein Kolben, der beim Setzen des Grubenstempels durch Preßluft die als Füllmittel dienende Flüssigkeit in die andere Kammer einpreßt.According to the invention is in the chamber in which the inner punch does not occur, a piston that when the pit punch is set by compressed air forcing liquid serving as a filler into the other chamber.
Der Grubenstempel besteht aus seinem rohrförmigen Außenstempela, b, dessen Hohlraum durch ein von Hand zu öffnendes Ventil c in zwei Kammern a1, b1 unterteilt ist. In der Kammer a1 befindet sich der Kolben d des als Kolbenstange ausgebildeten Innenstempels e, der mit einer Druckplatte f zur Aufnahme des Quetschholzes g versehen ist. In der Kammer a1 ist unterhalb des Kolbens d im leeren Raum bei k .ein Luftkissen, das je nach dem Gebirgsdruck größer oder kleiner gewählt werden kann, -vorgesehen. In der Kammer bi befindet sich der Kolbenlt. Am unteren Ende des Außenstempels ist ein. Hahn, Ventil oder auch eine Muffe usw. zur Anbringung eines Preßluftanschlusses i angebracht. Unterhalb des Ventils c ist die Kammer bx mit einer Flussigkeit (Wasser, Öl, Tran usw.) gefüllt. Beim tiefsten Stand des Kolbens h steht die Flüssigkeit über Kolben I bis unmittelbar unter das Ventil c. Arbeitsvorgang Erst Ventil c, dann Ventil! öffnen. Durch den Anschluß i strömt Preßluft ein und drückt den Kolben h und damit die Flüssigkeit aus der Kammer b1 durch Ventil c in die Kammer ai. Der Kolben d wird hochgedrückt, und zwar so lange, bis der Stempel fest zwischen das Liegende und das Hangende gepreßt ist. Jetzt wird Ventil c geschlossen. Das Hangende kann nunmehr Druck bekommen, der Stempel kann nicht weichen. Die Wiedergewinnung dieser Stempel kann vollkommen gefahrlos geschehen dadurch, daß das Ventil c durch einen Draht, Haken oder Latte usw. aus einiger Entfernung geöffnet wird, um dann weggezogen zu werden.The pit punch consists of its tubular outer punch a, b, the cavity of which is divided into two chambers a1, b1 by a valve c that can be opened by hand. The piston d of the inner plunger e, which is designed as a piston rod and is provided with a pressure plate f for receiving the pinch wood g, is located in the chamber a1. In the chamber a1 there is an air cushion below the piston d in the empty space at k, which can be selected larger or smaller depending on the rock pressure. The piston is located in the chamber bi. At the bottom of the outside stamp is a. Faucet, valve or a sleeve etc. for attaching a compressed air connection i attached. Below the valve c, the chamber bx is filled with a liquid (water, oil, oil, etc.). When the piston h is at its lowest level, the liquid is above piston I to just below valve c. Work process First valve c, then valve ! to open. Compressed air flows in through connection i and pushes piston h and thus the liquid out of chamber b1 through valve c into chamber ai. The piston d is pushed up until the punch is pressed firmly between the lying and the hanging wall. Valve c is now closed. The hanging wall can now receive pressure, the stamp cannot give way. The recovery of these stamps can be done in a completely safe manner in that the valve c is opened by a wire, hook or lath, etc. from some distance, in order to then be pulled away.
