Claims8
A drive apparatus for a drill stem, in particular for de-coking systems, having a feeder (4) connected to a water supply (8) via a first interface (6) and to a drill stem (12) via a second interface (10), and having a drive (14) and a gearbox (16) for rotatably driving said feeder (4) and said drill stem (12), characterized in that
- said feeder (4) has a first water carrying section (20) releasably connected to said water supply (8) and a second water carrying section (40) connected to said drill stem (12) and said first (20) and second (40) sections are releasably connected to each other at a point above the gearbox,
- said first section (20) of said feeder (4) forming an assembly together with sealing elements (32) and said first interface (6), and
- said assembly being formed as a unit being removable from the feeder in a direction transverse to a central axis of the feeder (4) upon releasing the connection of the first water carrying section (20) to said water supply (8) and the connection of said first (20) and second (40) sections.
