Abstract
A drill stand for a core drilling machine (1) for driving an annular core bit (2) rotatable about a rotational axis (A) has a base plate formed of a post plate (3) and a vacuum plate (6) securable with each other with a possibility of displacement relative to each other in a plane (E) separating the post and vacuum plates (3,6), at least one post (5), an attachment element (4) for securing the post (5) on the post plate (3); and a vacuum planar attachment element (7) for mounting the base plate on a surface.
Claims11
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).
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 plane (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 plate (3) has a concave recess (13) open toward the rotational axis (A) of the annular core bit (2).
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 plane (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 a side of the post plate (3) adjacent to the vacuum plate (6) is shaped as a segment of a circle.
