geodetic instrumentation. SUBSTANCE: given theodolite is intended for survey and layout operations carried out in process of erection of building structures on inclined planes and for planning operations. Theodolite includes horizontal circle, telescope with cylindrical level, horizontal axis, additional axis for rotation of telescope, sector of worm wheel, worm wheel. Additional axis for rotation of telescope is perpendicular to horizontal axis. Telescope is bent in center part and has two rhombic prisms. Unit for attachment and inclination of additional axis of rotation of telescope has body in the form of cylindrical bushing made fast to horizontal axis. Axis of rotation of cylindrical bushing and additional axis coincide. Worm wheel is located on horizontal circle, interacts with sector of worm wheel and maintains kinematic coupling with counter. Plane of sector of worm wheel is perpendicular to horizontal axis. EFFECT: increased labor productivity thanks to expansion of area of site covered by planning operation from single station. 3 dwg |
