Abstract

L'appareil de forme tubulaire 1 contient des instruments 4 et 5 de mesure de l'inclinaison et de l'orientation, par exemple un clinomètre et un compas gyroscopique, et une caméra de télévision 6 qui envoie des images des cadrans des instruments à un moniteur et à un magnetoscope 10 placés en surface. L'appareil 1 est centré positivement par des doigts mobiles radialement, qu'un moteur met en extension au moyen d'un pignon et de crémaillère. Des doigts de mesure du calibre du trou sont mis en extension à des instants voulus, sous l'action d'un mécanisme hydraulique.The tubular device 1 contains instruments 4 and 5 for measuring inclination and orientation, for example a clinometer and a gyroscopic compass, and a television camera 6 which sends images of the dials of the instruments to a monitor and a VCR 10 placed on the surface. The device 1 is centered positively by radially movable fingers, which a motor sets in extension by means of a pinion and rack. Hole gauge measuring fingers are extended at desired times under the action of a hydraulic mechanism.
