Description
Grubenstempelkopf. Die Erfindung betrifft einen Grubenstempelkopf zur Aufnahme des gegen das Hangende zu legenden Rundholzes. Das Neue besteht darin, daß das Rohrstück mit halbkreisrundem Querschnitt in der Längsrichtung gebogen ist, so daß eine Rinnensohle entsteht, deren höchster Punkt in der Mitte der Sohle gerade über der senkrechten Mittellinie des Stempels liegt. Diese Anordnung hat den Vorteil, dem Stempel stets eine mittlere Belastung zu sichern, auch dann, wenn er sich aus irgendwelchen Gründen schief stellt.Pit punch head. The invention relates to a pit punch head to take up the round timber to be laid against the hanging wall. The new thing is that the pipe section is bent with a semicircular cross-section in the longitudinal direction, so that a gutter sole is created, the highest point of which is straight in the middle of the sole above the vertical center line of the punch. This arrangement has the advantage always ensure a medium load on the stamp, even when it is off for whatever reason.
Die Zeichnung veranschaulicht den neuen Stempelkopf beispielsweise in einem Langschnitt.The drawing illustrates the new stamp head, for example in a long cut.
Die etwa halbkreisrunde Rinne i dient dazu, daß das eingelegte Rundholz 2 nicht seitlich abgleitet. Der eigentliche Stützpunkt 3 des Stempelkopfes gegen das Rundholz und gegen das Hangende überträgt die Belastung, so daß in weiten Grenzen der Neigung der Stempel noch immer mittig beansprucht wird. In der Zeichnung ist absichtlich eine schräge Stellung des Stempels dargestellt, um zu zeigen, daß auch für diese Stempelneigung die Belastung keine einseitige Beanspruchung des Stempels erzeugt. Der Grubenstempelkopf nach der Erfindung kann 'bei den verschiedensten Stempelarten verwendet werden.The approximately semicircular channel i serves that the inserted round wood 2 does not slide sideways. The actual support point 3 of the punch head against the round timber and against the hanging wall transfers the load so that within wide limits the inclination of the punch is still stressed in the middle. In the drawing is intentionally shown an oblique position of the stamp to show that too for this punch tendency the load is no unilateral stress on the punch generated. The pit punch head according to the invention can 'with the most diverse Types of stamps are used.
