Abstract
Vorrichtung zur Steuerung eines Bohrgestänges mit einem das Bohrgestänge umgebenden Außengestänge, das an dem Bohrkopf zugewandten Ende eine das Bohrgestänge umfassende Exzentrische Führung aufweist, wobei ein Steuergehäuse (4) mit einer Führungsnut (5), in die ein Führungsstift (6) greift, exzentrisch und derart drehbar in dem Außengestänge (3) gelagert ist, daß einer Axialverschiebung des Außengestänges (3) eine Veränderung der Führung des Bohrgestänges (1) bewirkt. Device for controlling a drill pipe with an outer pipe surrounding the drill pipe, which has an eccentric guide comprising the drill pipe at the end facing the drill head, a control housing (4) having a guide groove (5) into which a guide pin (6) engages, eccentrically and is rotatably mounted in the outer rod (3) in such a way that an axial displacement of the outer rod (3) causes a change in the guidance of the drill rod (1).
