Embodiment Construction

[0026] A first embodiment of a drilling device according to the invention is shown in FIG. 1 . The drilling device has a base plate 1 on which a column 2 is rotatably arranged. The bracket 22 is arranged on the column 2 , and the bracket 22 can move along the column 2 in a drilling direction.

[0027] The drill drive 11 designed as a rotary drive is arranged on the bracket 22, and the drill pipe 6 is arranged on the output shaft 19 of the drill drive 11 in a rotationally mounted, eg axially mounted manner. The drill pipe 6 is rotatable by operating the drill drive 11 . By moving the carriage 22 the drill pipe 6 can be moved axially by the drill drive 11 in the drilling direction. The drill pipe 6 is coupled to the output shaft 19 by means of a detachable pipe connector 18 arranged on the lower end of the output shaft 19 .

[0028] The drill pipe 6 can be designed in several sections comprising a plurality of pipe elements interconnected by separable pipe connectors. At the...
