Description
Kappschuh aus Flacheisen, dessen umgebogenes unteres Ende dem Stempel gegen den Seitendruck ein nachgiebiges Widerlager bietet Gegenstand der Erfindung ist ein nachgiebiger schmiedeeiserner Kappschuh für den Grubenausbau.Cutting shoe made of flat iron, the bent lower end of which is attached to the stamp a resilient abutment against the side pressure provides the subject of the invention is a resilient wrought iron cap shoe for pit lining.
Das Neue besteht darin, daß die vordere Anlage des Kappschubes an den Stempel aus einem halben Hohlzylinder besteht, dessen Mantel an seinem unteren Ende spiralig nach innen zu einem Zylinder geringen Durchmessers eingerollt ist, um bei wechselndem seitlichen Gebirgsdruck nach Streckung und fortlaufender Kürzung des Halbzylindermantels infolge Indiestreckewanderns des Stempelkopfes dessen Vorwärtsbewegung zu begrenzen.The novelty is that the front attachment of the Kappschubes on the stamp consists of half a hollow cylinder, the jacket of which at its lower The end is curled spirally inwards to form a cylinder of small diameter, around with changing lateral rock pressure after stretching and continuous shortening of the half-cylinder jacket as a result of the die head's forward movement in the indie stretch to limit.
Wie aus der Zeichnung ersichtlich ist, wirkt bei beginnendem Seitendruck der überhaupt mögliche längste Hebelarm auf die an der vorderen Anlagefläche des Kappschuhes an die Schiene befindliche Biegestelle, während bei fortschreitendem Druck dieser Hebelarm fortschreitend kürzer wird, wodurch naturgemäß der dem Vorwärtswandern des Stempelkopfes entgegengesetzte Widerstand sich fortlaufend verstärkt.As can be seen from the drawing, it works when the side pressure starts the longest lever arm possible at all on the at the front contact surface of the Kappschuhes on the rail located bending point, while advancing The pressure of this lever arm becomes progressively shorter, which naturally results in the forward hike the opposite resistance of the punch head increases continuously.
Die Erfindung hat gegenüber dem bisher Bekannten den Vorteil einer größeren Nachgiebigkeit. Dies bezieht sich sowohl auf die Kappschuhe, bei denen das untere Schenkelende parallel zu sich selbst umgebogen ist, als auch auf die Kappschuhe mit splintar tig gebogenem Eisenband. Bei dem letzteren besitzen die von dem Auge umschlossenen Einsatzstücke bei der unbedingten und nicht zu vermeidenden Verschiedenheit ihrer Härte ganz verschiedene Widerstände, während bei dieser Erfindung der Widerstand in jedem Kappschuh der gleiche und ein absolut gleichmäßig sich steigernder ist.The invention has the advantage over the previously known greater compliance. This applies to both the slippers where the lower leg end is bent parallel to itself, as well as on the Heeled shoes with a splint-like bent iron band. In the case of the latter, the inserts enclosed by the eye in the case of the unconditional and unavoidable Differences in hardness quite different resistances, while in this invention the resistance in each cutting shoe is the same and an absolutely evenly increasing one is.
