PLANT FOR INCLINOMETER ADJUSTMENT AND EXPERIMENTAL RESEARCHES Russian patent published in 2002 - IPC

FIELD: researches of boreholes, more specifically, complexes of researches and stand testing of new type of inclinometers, particularly, adjustment and balancing of their sensitive members. SUBSTANCE: plant has U-shaped support in the form of plate and two vertical posts; the first platform with fastening units to stationary base; the second platform installed between plate and the first platform coaxially with them and having stop of orthogonal fixation. The first platform has four recesses equidistant from its generating surface. The third platform is made with cantilevered semiaxles which are connected through rotation bearings with upper parts of vertical posts. Unit for fastening of inclinometer body is made in the form of two handwheels, cylinders and changeable collet. Handwheels are connected with cylinder by thread. Changeable collet is located in cylinder coaxially with it. Plant also has three discs of worm gearings. The first disc is rigidly connected with plate and horizontally located. The second disc is rigidly connected with cylinder of unit of fastening of inclinometer body. Installed parallel to discs are three dials of angle coarse reading. Deal of angle of sight is rigidly connected with the second disc. Azimuth dial is connected with plate by means of two thread fastening units. Connected with discs are three spring-located worms by means of worm gearing. The third disk with zenith angle dial whose scale is located from external side of vertical post, is rigidly connected with one of semiaxles of the third platform. Dials of angle coarse reading are conjugated directly with fine reading dials. Dial of azimuth angle accurate measurement is rigidly secured to the second platform. Dial of zenith angle accurate measurement is secured to respective vertical post. Dial of sight angle accurate measurement is installed on the third platform. Instrument table is installed on the second semiaxle against unit of fastening of inclinometer body. EFFECT: extended performance potentialities, higher accuracy of measurement and convenience in operation. 8 dwg
