Description
Nachgiebiger Grubenste'iripel oder Ausbaurahmen Der Erfindungsgegenstand ist ein nachgiebiger Grubenstempel oder Ausbaurahmen, dessen 'mit schrägen Verbindungsflächen überlappend zusammenstoßenden Teile durch Schellen und durch zwischen diese und die Ausbauteile eingetriebene Keilte ,aus nachgiebigem Werkstoff klemmfest zusammengehalten. werden. Derartige Grubenstempel sind bekannt. Nach der Erfindung sind die Schrägflächen der Ausbauteile in einem stumpfen Winkel derart gebrochen, daß die Knicklinie senkrecht zur Ebene des Ausbaurahmens bzw. zur Längsachse des Stempels liegt. Hierdurch wird gegenüber dem Bekannten der Vorteil erzielt, daß sich die Ausbauteile zunächst starr gegeneinander abstützen und erst bei zunehmender Druckbelastung verschieben, d. h. nachgiebig werden, wobei erst jetzt die klemmfeste Schellenverbindung ausschließlich -beansprucht wird.Resilient Grubenste'iripel or extension frame The subject of the invention is a flexible pit punch or support frame, whose 'with sloping connecting surfaces overlapping colliding parts by clamps and by between these and the expansion parts are driven in wedges, made of flexible material, held together so that they cannot be clamped. will. Such pit punches are known. According to the invention, the inclined surfaces the extension parts broken at an obtuse angle in such a way that the kink line is perpendicular to the level of the expansion frame or to the longitudinal axis of the punch. This will over the known achieved the advantage that the expansion parts are initially rigid support each other and only move when the pressure load increases, d. H. become yielding, only now the clamp-proof clamp connection exclusively - is claimed.
Erwähnt sei noch, daß ein starrer Grubenstempel bekannt ist, der lediglich zum Zwecke des bequemeren Wiedergewinnens durch treppenartig ausgebildete Schnitte unterteilt ist und ,auseinanderfällt, sobald die Halteschelle gelöst wird. Dieser Stempel besitzt keinerlei Nachgiebigkeit.It should also be mentioned that a rigid pit stamp is known which is only for the purpose of more convenient retrieval through stair-like cuts is divided and falls apart as soon as the retaining clip is loosened. This The stamp has no resilience whatsoever.
In den Zeichnungen sind zwei Ausbaurahmen als Ausführungsbeispiele der Erfindung schematisch dargestellt.In the drawings, two support frames are shown as exemplary embodiments of the invention shown schematically.
In den Abb. i und z bezeichnen die Buchstaben A den Schrägschnitt, B die Schelle und C den Keil. Die in Abb.3 beispielsweise dargestellte Schelle A ist an ihren Längsseiten entsprechend dem verwendeten Schienenprofil B eingedrückt. Mit ihrer Unterseite steht die Schelle entsprechend der zu verwendenden Keilstärke vom Schienenfuß ab. Beginnen nun die beiden überlappten und von Schelle und Keil zusammengehaltenen Enden der Einzelteile bei Druckbeanspruchungen an ihren Schrägschnitten zu gleiten, so wird zunächst der Keil, der z. B. aus Holz bestehen kann, bis zu einem gewissen Grade zusamrriengepreßt werden. Bei zunehmenden und namentlich plötzlichen Beanspruchungen werden sich die profilierten Längsseiten der Schelle strecken.In Figs. I and z, the letters A denote the bevel cut, B the clamp and C the wedge. The clamp A shown in Fig. 3, for example, is pressed in on its long sides in accordance with the rail profile B used. With its underside, the clamp protrudes from the rail foot according to the wedge thickness to be used. Now start the two overlapped and held together by clamp and wedge ends of the items under pressure loads on their bevel cuts, so first the wedge, the z. B. made of wood can be compressed to a certain extent. With increasing and especially sudden loads, the profiled long sides of the clamp will stretch.
