Abstract:
1. A drill stand for a core drilling machine ( 1 ) for driving an annular core bit ( 2 ) rotatable about a rotational axis (A), the drill stand comprising post ( 5 ) for supporting the core drilling machine ( 1 ); a base plate for supporting the post ( 5 ) and extending in a plane (E) extending substantially transverse to the rotational axis (A) of the core bit ( 2 ), the base plate being formed of a post plate ( 3 ) and a vacuum plate ( 6 ) securable with each other with a possibility of both linear displacement relative to each other in the place (E) the base plate extends, and pivotal movement relative to each other; post attachment means ( 4 ) for securing the post ( 5 ) on the post plate ( 3 ) and linearly displaceable in the plane of the base plate; and vacuum attachment means ( 7 ) for mounting the vacuum plate ( 6 ) and, thereby, the base plate on a surface, wherein the post ( 5 ) comprises two upright posts ( 5 ), spaced from each other and extending parallel to each other and being arranged circumferentially with respect to the rotational axis (A) of the annular core bit ( 2 ).
