(54) (57) The goniometric device for surveying GIROKOSHLSA comprising telescope with autocollimation eyepiece and located coaxially with gnroblokrm READOUT th device comprising a horizontal limb system transfer image diametrically opposite grooves formed in the form of an optical bridge of two prisms RA-90 ° and two-lens wrapping system, the second two-lens wrapping system

and an optical micrometer, so that, in order to reduce the dimensions of the gyrocompass, the horizontal limb is rigidly fixed on the vertical axis of the gyroblock, into the optical channel of the telescope, enter a block of two rectangular prisms .РБ-186 and AR-90, with the BR-180 ° prism, the hypotenuse of which is connected to the catheter face of the AR-90 ° prism, is installed perpendicular to the horizontal axis of the giroblok and the optical axis of the visual axis, and three BM-EO prisms are added to the reading device, with This prism AkR-90 ° optical bridge is placed En between the output face of an AR-90 ° prism and the first lens of the optical bridge wrapping system, the second lens of which is optically coupled to the input of the optical micrometer through the first prism BM-90 ° - 90 °, the horizontal limb, the second prism BM, sequentially installed on the same optical axis -90 ° - 90 °, the second two-lens wrapping system and the third prism BM-90 ° - 90 °. The invention relates to the field of gyroscopic instrumentation is can be used in the development of precision small surveying gyrocompasses. The aim of the invention is to reduce the DiFHHe dimensions of the surveying gyrocompass. Fig. 1 shows a diagram of a reading device; Fig.2 is a diagram of the telescope. The reading device (Fig. 1) contains a light source 1, located below the horizontal limb 2, an optical bridge, with which the image of limb strokes is transferred to the diametrically opposite part of the limb, consisting of prism AP-90 ° 3, prism AKP-90 ° 4 , lenses 5 and 6 of the first inverting system and the prism BM-90 ° - 907, the prism BM-90 90 ° 8, which is diametrically opposite to the light source 1; lenses 9 and 10 of the second inverting system, the output of which is optically coupled to the input of an optical micrometer 12 through a BM-90 ° - 90 ° 11 prism; the output of which is through sequentially installed prisms AP-90 ° 13 and BP-90 14 optically connected to a microscope , containing an example lens 15 and an eyepiece 16. The telescope (Fig. 2) contains an inlet nozzle 17, behind which a swivel mirror 18 fixed on a horizontal axis and optically connected to the inlet catheter face of prism AR-90 ° 19, an exit catheter face which is connected with the z-mortgage edge of the prism BR- 180 ° 20, mounted in front of the lens 21, in the image plane of which a grid 22 of an autocollimation eyepiece is located, consisting of a light source 23, an illuminating prism 24 glued to the grid 22, and an eye lens 25, and a mirror 26 of the gyromotor 27 placed inside the gyroblock 28. The reading device works in a barely dull way. The light beam from the light source 1 falls on the detected part of limb 2, the image of the strokes of which with the help of an optical tick system including prisms 3 and 4, lenses 5 and 6 of the first reversing system and prism 7, bypassing the gyroblock 28, placed in the center of the limb 2 (Fig. 2), is projected into the plane of the strokes of the second diametrically opposite side of the limb. Further, images focused on one plane of diametrically opposed limb strokes by a prism 8, lenses 9 and 10 of the second wrapping system and prism 11 are directed to an optical micrometer system 12, out of which, prisms 13 and 14 are transmitted to the lens 15 of the microscope projecting strokes in the focal plane of the ocular is 16. The sighting channel of the telescope works as follows. Light from an object through an entrance window 17 hits a rotating mirror-18, reflected from which, hits a catheter face of a prism 19, then onto a hypotenuse face of a prism 20, coming out of which, is directed into an objective 21 forming an image of the object in the grid plane 22, placed in the focal plane, the ocular 25, which is viewed by the ocular 25. 25. The autocollimation channel of the telescope works as follows. The rays from the light source 23 are directed by an illuminating prism 24, on that part of the grid 22 where the test object (bisector) is applied, the lens passes and a parallel beam is fed to the hypotenuse edge of the prism 20, then to the mirror 26 of the gyromotor 27. Reflecting from the mirror 26, in the reverse direction, the rays in the focal plane of the lens form an autocollimation image of the test object, which is observed in the eyepiece p 25 of the telescope. Thus, the introduction of additional elements into the proposed goniometer device makes it possible to obtain a layout that allows the goniometric device and the gyro unit to be placed in one case, and thereby reduce the size and weight of the gyrocompass while maintaining the high accuracy found the geani needed for surveying work.
