Description
11-förmiger Kappschuh--für den eisernen Grubenausbau Es sind Kappschuhe für den eisernen Grubenausbau mit verstrebten Widerlagern bekannt, die aus einem Stück Blech im Gesenk durch Pressen hergestellt sind.11-shaped chopping shoe - for iron pit lining. They are chopping shoes known for the iron mine support with braced abutments that consist of a Pieces of sheet metal in the die are made by pressing.
Auch ist es bekannt, das Mittelstück eines Kappschubes, dessen Widerlager nicht verstrebt sind, durch eine wellenartige Verformung, die quer geschlitzt ist, so zu gestalten, daß sie den Steg des eisernen Stempels im Schlitz .erfaßt, also seitlich festlegt.It is also known, the center piece of a Kappschubes, its abutment are not braced, due to a wave-like deformation that is slit transversely, to make it so that it grips the web of the iron stamp in the slot, that is laterally fixed.
Neu ist es, diese Verformung nicht wellenartig, sondern topfartig zu gestalten, derart also, daß das Mittelstück ausgekümpelt wird. Diese Verformung wird geschlitzt, damit der Steg des Stempels Raum- findet. Sie hat den Vorzug, daß der Schuh widerstandsfähiger bleibt. Das ist namentlich dann der Fall, wenn die zwischen den Widerlagern und dem Mittelstück vorgesehenen, an sich bekannten Verstrebungen bis etwa zur Mitte der Kümpelung vorgezogen werden; denn die Endstelle dieser Verstrebungen bildet immer die schwächste Stelle des Kappschuhes, die aber bei Gegenwart der Kümpelung durch diese selbst wiederum erheblich verstärkt wird.What is new is that this deformation is not wave-like, but pot-like to shape, so in such a way that the middle piece is dislodged. This deformation is slotted so that the web of the stamp finds space. It has the merit that the shoe remains more resistant. This is particularly the case when the between the abutments and the center piece provided, known struts be brought forward until about the middle of the dishing; because the end of these struts always forms the weakest point of the cap shoe, but it does so in the presence of the dished is in turn considerably reinforced by this itself.
In der Zeichnung ist die Erfindung in fünf Figuren dargestellt.In the drawing, the invention is shown in five figures.
F ig. I zeigt eine Seitenansicht, Fig. 2 eine Vorderansicht; Fig.3 einen Grundriß, Fig. q. einen Schnitt nach A-B und Fig. 5 eine schaubildliche Darstellung.Fig. I shows a side view, FIG. 2 shows a front view; Fig. 3 a plan, Fig. q. a section according to A-B and FIG. 5 a diagrammatic representation.
Der Kappschuh ist aus Walzeisen durch Pressen hergestellt. An den Mittelteil schließen sich zwei Widerlager an. Das Widerlag-er a, das den Schlitz b besitzt, dient als Widerlager für die zumeist aus einer abgelegten Schiene bestehende Kappe c, die sich mit ihrem Steg in den Schlitz b einlagert. Gegen das Widerlager d legt sich der Stempele. Die Lage des Stempels ist durch den Schlitz f seitwärts gesichert. Dieser Schlitz befindet sich in einer Auskümpelung g des Schuhmittelteiles, der gerundet oder spitz zulaufen kann. Die Widerlager a und d sind mit dem Mittelteil durch die Verstrebungen k und i verbunden, so daß sie gegen Aufbiegen gut abgestützt sind. Diese Verstrebungen la und i enden nachbarlich bei k, und diese Endstelle liegt in Höhe der Auskümpelung g, die durch ihre auskragende Wandung eine wesentliche Verstärkung dieser an sich schwachen Stelle herbeiführt; die Steile k wird also durch die gekümpelten Wände überbrückt. Die Rippe l dient in an sich bekannter Weise dazu, das Widerlager d zu versteifen.The cutting shoe is made from rolled iron by pressing. Two abutments adjoin the middle part. The abutment-er a, which has the slot b , serves as an abutment for the cap c, which mostly consists of a stored rail and is embedded with its web in the slot b. The stamp rests against the abutment d. The position of the stamp is secured laterally by the slot f. This slot is located in a bulging g of the middle part of the shoe, which can be rounded or tapered to a point. The abutments a and d are connected to the middle part by the struts k and i, so that they are well supported against bending open. These struts la and i end next to k, and this end point is at the level of the bulging g, which, through its protruding wall, brings about a substantial reinforcement of this weak point; the steep k is bridged by the sloping walls. The rib l is used in a manner known per se to stiffen the abutment d.
