DEVICE FOR INSTALLATION OF GEODETIC BEACON Russian patent published in 1997 - IPC

FIELD: geodetic instrument engineering, applicable in satellite geodesy. SUBSTANCE: the device uses a carrier, spring plate and a bedplate joined by screws and having axial holes alternately installed in which are the working bush and the centering member consisting of an adjusting rod with the geodetic beacon, supporting bush and head with a level, use is made of a collet chuck threaded on the adjusting rod and placed inside the supporting bush. The collet is made in the form of a nut with tapered lugs and slots on both ends, the slots are staggered and have a length exceeding a half of the collet length. One tapered lug is positioned in the bottom part of the supporting tapered bush, and fitted on the other lug is a clamp in the form of a hollow screw with an internal cone on the threaded side. The bedplate has unfastening members installed in holes and made in the form of an external bush with an eccentric threaded hole, which receives the internal bush resting on the ground surface and the rod installed in the internal bush and dipped in the ground. EFFECT: enhanced accuracy of measurement of geodetic beacon coordinates in three-dimensional space. 3 dwg
