Description
Technical field
The present invention relates to a kind of measurement reflecting prism, particularly the big sphere ball-type of magnetic is measured reflecting prism.
Background technology
At survey field, total powerstation is to obtain the very important equipment of spatial data.Total powerstation, promptly full site type electronic tachometer (Electronic Total Station).Being a kind of light harvesting, mechanical, electrically being the hi-tech surveying instrument of one, is to catchment the straight angle, vertical angle, distance (oblique distance, flat apart from), vertical survey function in the instrument of surveying and mapping system of one.Once settle instrument because of it and just can accomplish whole surveying works on this survey station, so be referred to as total powerstation.The total powerstation range measurement principle is that total powerstation sends light wave, and light wave runs into measuring object, and light wave is reflected, and calculates the transmission time of light wave, just can know that total powerstation is to the distance between the measuring object.So the total powerstation range finding must have light wave to be reflected; Some instrument has the non-prism distance measurement function at present, does not promptly need prism, and general reflectance target just can be found range; But this measuring distance is short; Measuring accuracy is low, also has only the part instrument to have such function, all will use reflecting prism under the exhausted big situation in the actual measurement.Total powerstation is through recording distance and the angular relationship between instrument and the prism, and the locus that can learn prism then through prism and spatial relationship testee, can obtain the locus of testee.
Because prism can not be vertical with the measurement light wave fully in instrumentation; So measuring prism is designed to the glass-reflected body of three mutually perpendicular reflectings surface and a face of tool; Incident ray is through reflecting behind several secondary reflections from vitreum like this; Emergent ray is parallel with incident ray, turns back to total powerstation, and total powerstation calculates total powerstation to the distance between the reflecting prism according to the propagation principle of light wave.During actual measurement, even always hope that the reflection kernel of prism remains unchanged under the situation of prism face of tool out of plumb light wave; The prism locus that obtains like this is only accurately, so during the design prism, require prism rotation transverse axis crossing with vertical rotary shaft; And follow the reflection kernel of prism to overlap; Be difficult in the production assembling process guarantee this point,, and overlap with the reflection kernel of prism so common prism seldom can accomplish to rotate transverse axis basically and vertical rotary shaft intersects.Contain this in the final measurement achievement because the error that the drift of prismatic reflection center produces, the precision of measurement achievement and accuracy decline.
Obtain the prism locus, calculate the locus of testee through the theoretical spatial relationship between prism and the testee.Common prism is owing to processing and assembling reason; So same model prism consistance is relatively poor; Measure same object with different prisms like this, the spatial relationship between prism and the testee is not fixed, and changes; And this species diversity causes final measurement achievement to contain because the error that the inconsistency of prism produces, the precision of measurement achievement and accuracy decline.
ZL97190034.5 has announced a kind of measurement ball reflector; Be through three each other the screw of 120 degree angles adjust the position of glass-reflected body; Make the reflection kernel of glass-reflected body be positioned at the spheroid centre of sphere, from preformed hole, insert silica gel then the glass-reflected body is fixed.In the actual production assembling process, adjustment glass-reflected body position difficulty is inserted silica gel and possibly changed the glass-reflected body position afterwards.
ZL20081030406.3 has announced a kind of ball type measuring prism; Through being installed in front and rear covers and the even position of regulating the glass-reflected body of orientation angle on the through hole that passes ball; Through hole makes the spheroid area of spherical surface tail off, the limited adjustment range of prism like this, and can't satisfy is the requirement of big angle of depression observation.Spheroid itself does not have magnetic in addition, and is then very high to the mounting object requirement, often need make special-purpose installing component, and versatility is poor.
Summary of the invention
The present invention is directed to the shortcoming of drift of common prismatic reflection center and consistance difference; Measure ball the allotment difficulty is installed; The glass-reflected body position is prone to the shortcoming of change, and ball type measuring prism limited adjustment range, the shortcoming that needs to make special-purpose installing component, provides a kind of installation easy to adjust; Has magnetic, the measurement reflection sphere of big sphere.
Be elaborated below in conjunction with accompanying drawing:
Like Fig. 1, the present invention includes magnetic spheres (1), a blind hole (2) is arranged on magnetic spheres (1); The centre of sphere of magnetic spheres (1) is positioned on the axis of blind hole (2), through the control machining precision, make that glass-reflected body (3) and erecting frame (4) are combined closely after; The reflection kernel of glass-reflected body (3) is positioned on erecting frame (4) column axis; Glass-reflected body (3) face of tool diameter, erecting frame (4) external diameter are consistent with blind hole (2) diameter, and glass-reflected body (3), erecting frame (4) are installed in the blind hole (2), and slide before and after can be in blind hole (2); Adjusting ring (5) is installed in blind hole (2) front end; Fix and adjusting glass-reflected body (3) and erecting frame (4), adjusting screw(rod) (7) is installed on the magnetic spheres (1), rotates adjusting ring (5) and adjusting screw(rod) (7); Can promote glass-reflected body (3) and erecting frame (4) front and back in blind hole (2) and slide, make the reflection kernel of glass-reflected body (3) overlap with the centre of sphere of spheroid (1).
Spheroid of the present invention (1) is from carrying magnetic, and is easy for installation.Big sphere can satisfy the high elevation angle and the observation requirement of the big angle of depression.Make the glass-reflected body (3) that is installed on the erecting frame (4) in blind hole (2), move forward and backward through reconciling circle (5) and adjusting screw(rod) (7), thereby make the reflection kernel of glass-reflected body (3) be positioned on spheroid (1) centre of sphere.In any case rotate magnetic large ball games planar survey reflection sphere; The position of the reflection kernel of glass-reflected body (3) in spheroid (1) is thick-and-thin; Thereby the magnetic large ball games planar survey reflection sphere locus that obtains is accurately; And the relation between spheroid (1) and the Measuring Object is fixed, and the locus of Measuring Object is accurately like this, has solved the problem of drift of prismatic reflection center and prism inconsistency.The precision and the accuracy of measuring achievement have all improved.
