THEODOLITE SETTING INCLINED PLANES Russian patent published in 2000 - IPC

FIELD: geodetic instrumentation. SUBSTANCE: invention is intended for taking out such inclined planes to nature where design provides for inclination along two axes. Theodolite has limb, alidade, supports put on alidade, horizontal axis carrying vertical plate, unit for attachment and inclination of additional axis of rotation of telescope. Unit for attachment and inclination of additional axis has case made fast to horizontal axis, cylindrical member, additional axis of rotation of telescope put on cylindrical member, sector of worm wheel made fast to cylindrical member, worm mounted on case for interaction with gear of worm wheel and having handle on one end and gear on the other end which provides for kinematic coupling with reading unit. Telescope made fast to additional axis is bent in central part and two rhombic prisms are placed inside it. EFFECT: enhanced productivity thanks to avoidance of precomputation of general gradient and of seeking for azimuthal direction of this greatest gradient on locality. 4 dwg
