(FR) ENSEMBLE BUSE DE CHARGE
Abstract
(EN)
The invention provides a rock drill adaptor which makes use of the supportive function of a rock drill associated with an air leg or a similar mounting device (hereinafter also referred to as "a vertically extensible support") as a means to inflate a pressure vessel, such as a rock bolt, and retain a mesh support against a rock wall simultaneously.
(FR)
L'invention concerne un adaptateur de trépan qui utilise la fonction de support d'un trépan associé à une béquille pneumatique ou à un dispositif de montage similaire, tel que celui décrit dans la description de ZA2009/07868 (ci-après également désigné par « support verticalement extensible »), comme moyen pour gonfler une cuve sous pression, telle qu'un boulon d'ancrage, et retenir simultanément un support de maille contre une paroi rocheuse.
