Bernd Heltewig Leichtbohrkronenrohr-DeckelBernd Heltewig lightweight core bit tube cover

BESCHREIBUNGDESCRIPTION

Gegenstand meiner Gebrauchsmusterschutzajimeldung ist ein Bohrkronenrohr, bestehend aus dem Mantel ( 1 ), dem mit gewichtssparenden Materialausnehmungen ( 2 ) versehenem Deckel (3) und der Abdeckplatte ( 4 ) .The subject of my utility model application is a drill bit tube, consisting of the casing ( 1 ), the cover ( 3 ) provided with weight-saving material recesses ( 2 ) and the cover plate ( 4 ).

Anzahl und Größe der gewichtssparenden Materialausnehmungen ( 2 ) im Deckel ( 3 ) richtet sich, statisch bedingt, nach dem jeweiligen Bohrkronenrohr-Durchmesser und dem Antriebswellendruck, wobei die Durchbiegung des ganzen Deckels ( 3 ) berücksichtigt wird.The number and size of the weight-saving material recesses ( 2 ) in the cover ( 3 ) depends, for static reasons, on the respective drill bit tube diameter and the drive shaft pressure, whereby the deflection of the entire cover ( 3 ) is taken into account.

Die Abdeckplatte ( 4 ) verhindert während des Betriebes den Austritt des im Bohrkronenrohr befindlichen Kühlwassers.The cover plate ( 4 ) prevents the cooling water in the drill bit tube from escaping during operation.

Im Gegensatz zu herkömmlichen Bohrkronenrohrdeckeln, sind die Bohrkronenrohrdeckel ( 3 ) mit Materialausnehmungen gewichtsmäßig leichter und beim Transport sowie bei Bohrarbeiten wesentlich besser zu handhaben.In contrast to conventional core bit tube covers, the core bit tube covers ( 3 ) with material recesses are lighter in weight and are much easier to handle during transport and drilling work.
