Abstract
(EN) A tittle obliquity measurer, comprises a housing(1), a gravity pendulum(3), a set of gears(2), and a indication device(4). The power shaft(210) of the gears is fixed on the housing, and is parallel to the bottom surface of the housing. The gravity pendulum and the power gear are integrated. When the tittle obliquity measurer is tilted, the gravity pendulum rotates all the gears, and the bottom surface of the housing may be normal to the central line of a vertical shaft which is to be measured, the bottom surface of the housing may be normal to and be crossed with the approximate plumb surface at the horizontal line which is parallel to the power shaft, the indication device can indicate the obliquity. The tittle obliquity measurer may have the two sets of gears with power shafts be normal with each other and be parallel to the bottom surface of the housing.
(FR) L'invention concerne un appareil de mesure de faible angle d'inclinaison comprenant un boîtier (1), un pendule de gravité (3), un ensemble de pignons (2) et un dispositif indicateur (4). L'arbre d'entraînement (210) des pignons est fixé au boîtier et est parallèle à la surface inférieure du boîtier. Le pendule de gravité et le pignon d'entraînement sont intégrés. Lorsque l'appareil de mesure est incliné, le pendule de gravité fait tourner tous les pignons et la surface inférieure du boitier peut être perpendiculaire à l'axe central de l'arbre vertical à mesurer. La surface inférieure du boîtier peut être perpendiculaire et traversée par la surface d'aplomb approximative au niveau de la ligne horizontale qui est parallèle à l'arbre d'entraînement. Le dispositif indicateur peut alors indiquer l'obliquité. L'appareil de mesure considéré peut être équipé de deux ensembles de pignons avec des arbres menants perpendiculaires l'un à l'autre et parallèles à la surface inférieure du boîtier.
