Title
(EN) A DRILL STAND FOR A CONCRETE DRILLING DEVICE WITH A LEVEL INDICATOR
(FR) SUPPORT DE FOREUSE POUR APPAREIL À FORER LE BÉTON AVEC INDICATEUR DE NIVEAU
Abstract
(EN)
A drill stand (3) for a concrete drilling apparatus having a concrete drill (1) and a drilling device (2) for rotating the concrete drill (1), said drill stand (3) including a support device (4) having a base (4') adapted to be anchored to a floor, a wall, or fitted to a structure that in turn is anchored in a suitable manner, said drill stand (3) further including a drill column (5) having a vertical normal position, a shaft member (6) by which one end of the drill column (5) is pivotally attached to the support device (4), means for adjusting an inclination of the pivotal drill column (5) in relation to the normal position, said drilling device (2) being mounted on the drill column (5) and movable there along toward and away from the pivotally attached end of the drill column (5), and means including a graduated arc (11) and a cooperating mark (12) movable relative each other along the graduated arc (11) for indicating an inclination of the drill column (5) in relation to its vertical normal position. To provide a drill stand with a drill inclination gauge(10) that is easy to read and can be used also on sloping surfaces without needing correction, the drill stand is provided with a level indicator (101), and a rotary member (103), on/in which the level indicator (101) is mounted, said rotary member (103) being mounted on/in said drilling device (2), and one of said mark (12) and cooperating graduated arc (11) being provided on said rotary member (103) and the other one being provided on said drilling device (2).
(FR)
L'invention concerne un support (3) de foreuse destiné à un appareil à forer le béton doté d’un trépan (1) à béton et d’un dispositif (2) de forage servant à faire tourner le trépan (1) à béton, ledit support (3) de foreuse comprenant un dispositif (4) d’appui doté d’un socle (4’) prévu pour être ancré à un plancher, un mur, ou monté sur une structure elle-même ancrée de manière appropriée, ledit support (3) de foreuse comportant en outre une colonne (5) de forage possédant une position normale verticale, un élément (6) d’arbre par lequel une extrémité de la colonne (5) de forage est en liaison pivot avec le dispositif (4) d’appui, un moyen de réglage de l’inclinaison de la colonne pivotante (5) de forage par rapport à la position normale, ledit dispositif (2) de forage étant monté sur la colonne (5) de forage et mobile le long de celle-ci de façon à être rapproché et éloigné de l’extrémité en liaison pivot de la colonne (5) de forage, et des moyens comprenant un arc gradué (11) et un repère associé (12) mobiles l’un par rapport à l’autre le long de l’arc gradué (11) afin d’indiquer une inclinaison de la colonne (5) de forage par rapport à sa position normale verticale. Afin de constituer un support de foreuse doté d’un indicateur (10) d’inclinaison de foreuse facile à lire et utilisable y compris sur des surfaces en pente sans nécessiter de correction, le support de foreuse est muni d’un indicateur (101) de niveau et d’un élément rotatif (103) sur / dans lequel est monté l’indicateur (101) de niveau, ledit élément rotatif (103) étant monté sur / dans ledit dispositif (2) de forage, l’un des éléments parmi ledit repère (12) et ledit arc gradué associé (11) étant installé sur ledit élément rotatif (103) et l’autre élément étant installé sur ledit dispositif (2) de forage.
