Description

Die Erfindung bezieht sich auf den Gebirgsdruck anzeigende mehrteilige Stempel oder Aush.auteile.The invention relates to the rock pressure indicating multi-part Stamp or stamping parts.

Mit anzeigenden Vorrichtungen für Gebirgsdruck ausgerüstete Stempel od. -dgl. sind in zahlreichen Ausführungsformen bekannt. Sämtlichen bekannten Konstruktionen ist jedoch verhältnismäßig geringe Tragkraft gemeinsam. Um diese Tragleraft zu vergrößern, sind an ihren Enden doppelt ausgebildete Stahlstempel vorgeschlagen worden. Diese besitzen jedoch den Nachteil, daß sich die Enden, die sich bei t@berlastung verbiegen, jeweils wieder treu gerichtet werden müssen. In der Praxis hat sich wegen der den bekannten Konstruktionen eigenen Nachteile keine derselben in nennenswertem Umfange einführen können.Stamps equipped with indicating devices for mountain pressure or the like are known in numerous embodiments. All known constructions however, they have a relatively low load capacity in common. In order to enlarge this portrayal, double steel punches have been proposed at their ends. These have the disadvantage, however, that the ends, which bend when overloaded, must be judged faithfully again in each case. In practice, because of the known constructions own disadvantages none of the same to any significant extent can introduce.

Durch die Erfindung wird ein Gebirgsdruck anzeigender Stempel von hoher Tragfähigkeit dadurch geschaffen, daß symmetrisch zu der in Druckrichtung stehenden Längsachse des Stempels zwei oder mehrere etwa gleichen Druck aufnehmende, in gewissem Abstand voneinander ohne Zwischenstück stehende Profileisen derart angeordnet sind, daß sie sich unter Einwirkung des Gebirgsdruckes zueinander verbiegen können, wobei das von außen erkennbare Maß der Durchbiegung -die Beobachtung des Gebirgsdruckes zuläßt. Die Benutzung der Durchbiegung der beiden Teile zueinander als Maßgröße ist von Vorteil, weil ihr Maß begrenzt ist bzw. im Endzustand, in welchem die tragenden Teile besonders stark gegen Knicken beansprucht sind, ein weiteres Durchbiegen nicht mehr erfolgen kann. Bei Entlastung geht die elastische Verformung wieder zurück, und der Stempel ist ohne Nachrichten wieder brauchbar.The invention provides a rock pressure indicating stamp of high load capacity created by being symmetrical to that in the direction of pressure standing longitudinal axis of the stamp two or more approximately equal pressure absorbing, at a certain distance from each other without an intermediate piece standing profile iron arranged in this way are that they can bend towards each other under the action of the mountain pressure, where the amount of deflection that can be seen from the outside - observation of the rock pressure allows. The use of the deflection of the two parts to one another as a measure is advantageous because its size is limited or in the final state in which the load-bearing Parts are particularly stressed against buckling, no further bending more can be done. When the load is removed, the elastic deformation goes back again, and the stamp can be used again without notice.

In. der Abbildung sind Horizontalschnitte durch die beiden Stempelteile dargestellt, und zwar links die beulen Stempelteile in der Normallage, in der Mitte in durch Druck etwas, einander genähertem Zustande und rechts in der Stellung, in der der weiteren elastischen Durchbiegung infolge des zur Anlagekommens der Stempelteile aneinander Halt geboten ist.In. the illustration are horizontal sections through the two stamp parts shown, on the left the bulging stamp parts in the normal position, in the middle in a condition somewhat closer to each other by pressure and on the right in the position in that of the further elastic deflection as a result of the punch parts coming into contact hold on to each other is required.

PATENTANSPRUCH: Den Gebirgsdruck anzeigender mehrteiliger Stempel oder Grubenausbauteil mit mehreren die Last elastisch aufnehmenden, etwa parallel zueinander angeordneten Druckelementen, gekennzeichnet durch eine solche Anordnung der Druekelemnente zueinander, daß sie im Zuge .der Druckaufnahme ausknickend oder sich durchbiegend zur Anlage aneinander kommen und damit ihre Durchbiegung begrenzt ist.
