Abstract
The utility model relates to a survey gyroscope. A magnetic compass is arranged on the coaxal position of a horizontal circle of the survey gyroscope and can complete the initial direction of the survey gyroscope in quick, convenient, and accurate form by making use of the characteristic of north direction of the magnetic compass. The magnetic compass has the same shaft with the horizontal circle. The utility model is suitable to directional tasks for the mobile launch of missile, etc. with high orientation time requirement.
Description
Technical field
The utility model relates to a kind of azimuthal slewing gyro-theodolite of independently measuring fast and easily.
Background technology
Present gyro-theodolite adopts split-type structural usually, be that gyroscope and transit are two independent device, during use both are installed together the JT-15 gyro-theodolite of T16 that Switzerland WILD company is arranged of the type and GAK1 gyro-theodolite, optical instrument factory, Xuzhou etc.
Transit mainly is made up of horizontal dial, altitude circle, vertical pivot, transverse axis, optical axis and pedestal etc.Gyroscope mainly is made up of gyrostatic shell, gyro, suspension strap and power supply.Gyroscope and transit are that all-in-one-piece is installed, and the gyro vector axis of the gyro that suspension strap hangs is swung near meridian ellipse, and the equilibrium position of its swing is exactly a meridian ellipse.When rotating the alidade of transit, the alidade that gyrostatic shell is also followed transit rotates together.When the equilibrium position of gyro swing was in the same vertical plane with optical axis, optical axis also just was in the meridian ellipse, had just determined the horizontal dial of transit and the relation in geographical north at this moment, had also just finished the orientation of transit.
The orientation of gyro-theodolite has four steps usually: set up and leveling instrument, summary orientation, thick orientation and accurate pointing.Summary is directed utilize separate with gyro-theodolite or only be placed on the gyro-theodolite, do not have the magnetic compass of accurate position relation with gyro-theodolite, and finish no accuracy requirement, time 1-number minute with other method.Thick orientation utilizes a small amount of observation data of gyro-theodolite to finish, thick directed precision ± 3 '--± 10 ' in, the time was generally about 5 minutes.Above-mentioned summary orientation, thick orientation need be finished step by step, and orientation time is long.
The utility model content
The purpose of this utility model is exactly to finish thick orientation for solving two steps of needs that the above-mentioned background technology exists, the problem that orientation time is long, provide a kind of simple in structure, orientation time short, can finish the gyro-theodolite of directed task fast.
The technical scheme that the utility model provides is: a kind of slewing gyro-theodolite, comprise gyroscope and transit and vertical pivot thereof, transit is provided with the reading device of alidade and horizontal dial and read level circle reading, it is characterized in that: magnetic compass is installed on the transit, and magnetic compass is coaxial with horizontal dial.
Above-mentioned magnetic compass is provided with the needle window.
Be marked with nill pointer on the above-mentioned needle window, the reading index of the reading device of nill pointer and horizontal dial be separated by 180 the degree.
The reading index of above-mentioned nill pointer, reading device and the axial line of vertical pivot are in same vertical plane.
The utility model adopts technique scheme, and the directed and thick orientation of summary of routine is merged into a step, and it is directed and thick directed promptly once to finish summary at short notice, and the precision of finishing thick orientation also is better than conventional method.Can be fast and accurately finish thick orientation, make the time of finishing total orientation shorten dramatically, this is for directed tasks such as the motor-driven emission of demanding guided missile of orientation time are seemed particularly important.
Because instrument sets up, leveling is the same with smart directed finishing, when not considering these times, conventional gyro-theodolite was finished the time of thick orientation greater than 5 minutes, precision ± 3 '--± 10 ' in, the time of finishing thick orientation with gyro-theodolite of the present utility model is less than 1 minute, and precision is better than ± 3 '.

Embodiment
Referring to Fig. 1～Fig. 4, the utility model comprises gyroscope 17 and transit 18 and vertical pivot 1 thereof, transit 18 is provided with the reading device 9 of alidade 7 and horizontal dial 10 and read level scale 10 readings, on the transit 18 magnetic compass is installed, and magnetic compass is coaxial with horizontal dial 10.
In vertical pivot 1 upper end of gyro-theodolite high precision bar shaped needle 2 is installed, its needle rotating shaft 3 is supported by metal (upper 4, part at the alidade 7 of the intersection point equal height of the line at two needle tips 5 and needle rotating shaft 3 is equipped with needle window 6, be carved with nill pointer 12 on the needle window 6 and delineate 13, head bearing 4 is fixing by support 8, vertical pivot 1 is equipped with horizontal dial 10, and light source 11 illuminates horizontal dial 10, and by reading device 9 read level scales 10 readings.
In actual use, at first set up gyro-theodolite, and according to the spirit lever leveling gyro-theodolite on the gyro-theodolite.Finished gyro-theodolite set up with leveling after, the alidade 7 of spinning top transit, seek the image at the needle tip 5 of needle 2 by needle window 6, and the image at needle tip 5 is freely swung in needle window 6, and the equilibrium position that makes swing is near the magnetic meridian plate, and lock transit this moment makes it no longer free to rotate.
Horizontal inching gear by gyro-theodolite, make the alidade 7 of gyro-theodolite rotate around vertical pivot 1, this moment, nill pointer 12 rotated with the alidade 7 of gyro-theodolite, when the south seeking pole at needle tip 5 overlaps with nill pointer 12, at this moment the line at two needle tips 5 just is in magnetic meridian plate, the reading index of the reading device 9 of horizontal dial 10 also is in magnetic meridian plate, and promptly the optical axis 14 of the telescope 15 of gyro-theodolite points to magnetic north.Because magnetic declination equals the angle between magnetic meridian and the geographic coordinate meridian, geographic coordinate north=magnetic north-correction of magnetic variation, for the zero reading that makes gyro-theodolite horizontal dial 10 corresponding with geographic north, when the south seeking pole at needle tip 5 overlaps with nill pointer 12, under the motionless situation of the alidade 7 of gyro-theodolite, rotate horizontal dial 10, make the reading=correction of magnetic variation of gyro-theodolite horizontal dial 10, when at this moment the alidade 7 of gyro-theodolite rotates, the reading of its horizontal dial 10 is exactly the position angle, has so just finished the thick orientation of gyro-theodolite.When around vertical pivot 1 spinning top transit when horizontal dial 10 readings are zero, the reading index of the reading device 9 of horizontal dial 10 is in geographical south, and the object lens 16 of telescope 15 are at geographic north, the optical axis 14 of telescope 15 is in the geographical meridian ellipse of locality.
Magnetic compass can adopt bar shaped, also can adopt circle or other shape.Magnetic compass can be positioned on the upper end of vertical pivot 1, also can be positioned on the lower end of vertical pivot 1.
