Abstract
The invention provides a calibrator for an optical plummet and is a specialized equipment for the efficient examination and calibration of the optical plummet of an optical theodolite, an electric theodolite and a total station instrument of the surveying and mapping field in particular. The calibrator for the optical plummet is adopted to examine the optical plummet and then the offset value of the optical plummet can be determined for correction. The invention has simple, convenient and shortcut operation and reliable performance.
Description
Affiliated technical field:
The present invention relates to mapping instrument technology field.Comprise the check and the correction of optical theodolite, electronic theodolite and total powerstation optical plummet.
Background technology:
At present both at home and abroad instrument factory and applying unit adopt the correction of testing of two kinds of ways to optical theodolite, electronic theodolite and total powerstation optical plummet are general:
1, the fixed correction method of parallel light tube is forced to proofread and correct to tested optical plummet, this way light-receiving tube structural limitations, and when factors vary such as the light pipe graticule is shaken, tested optical plummet can't be proofreaied and correct.Do not possess versatility.
2, actual observation method need be placed on instrument and is fixed on the foot rest, presses the rules operation that instrument uses, and the operator will have rich experience, and the operation of will standing for a long time.When detecting many instruments, exist shortcomings such as labour intensity is big, time-consuming, effort.
Summary of the invention:
The present invention's (optical plummet rectifier) is the specialized equipment of a kind of detection optical transit, electronic theodolite and total powerstation optical plummet.Can measure the cultellation deviation of optical plummet efficiently and accurately, provide the correction foundation for optical plummet.
Technical scheme of the present invention is:
The present invention is according to the parallel light tube principle, use 25 times of focal lengths, 130mm telescope to throw and make special-purpose parallel light tube, two graticules that are carved with crosshair are set in light pipe, regulate two slow motion screws that link to each other with graticule, can make the fine motion of graticule, measure the cultellation deviation of tested counter point device along orthogonal both direction.The present invention's (optical plummet rectifier) is a light source with the 6V illuminating lamp, and the parallel light tube tube bottom is equipped with two rolling bearings, a pressure bearing and a drag knob, can guarantee that the light pipe tube rotates reposefully flexibly and brakes.
The invention has the beneficial effects as follows:
1, improves the calibration precision.Owing to be subjected to the influence of various factors, with conventional method calibration optical plummet on 0.5m and 2 distances of 1.8m, guarantee its minimum to a deviation less than 2mm than difficult.And come the calibration adjustment just much easier with the optical plummet rectifier, satisfy fully and improved counter point device cultellation accuracy requirement (skew is less than 1mm).
2, alleviated labour intensity.With conventional method calibration optical plummet, the operator stands for a long time and rotates with instrument, and labour intensity is big.Come calibration with the optical plummet rectifier, before the operator is sitting in worktable, after transit is installed on the optical plummet rectifier, optical plummet eyepiece and human eye are in the same plane, be need not Anping by test examination instrument, the operator only need rotate the light pipe tube, can adjust light path neatly.
3, improved work efficiency.Counter point device of conventional method calibration needs 20 minutes, and only proofreading and correct with the optical plummet rectifier needed to finish in 5～10 minutes.
4, dexterous convenient.The optical plummet rectifier is simple in structure, flexible operation, stable performance, the operator is not had specific (special) requirements.Its work accuracy, reliability all are better than conventional calibration method.

Embodiment:
1, hand-held transit allows transit bottom centre threaded hole aim at the M16 screw on testing-calibrating instrument top, rotates the light pipe tube it is screwed, and rough Anping transit enters in the testing-calibrating instrument light pipe tube optical plummet optical axis.Before the operator was sitting in testing-calibrating instrument, in the calibration process, the optical plummet eyepiece was connected the 6v power supply towards the operator.
2, adjust the optical plummet focal length, see graticule I clearly, rotate two mutually perpendicular final motion screws that graticule I moves on the light tube, the crosshair intersection point of graticule I and the graduation circle on the optical plummet graticule are met as Fig. 2.
3, rotation light pipe tube 180 degree are braked on the locking light pipe tube and are turned round, and observe the axis that meets of counter point device graduation circle and graticule I.Rotation light pipe tube, if both are offset (Fig. 3), illustrate the counter point device optical axis in the 0.5m scope with transit feathering axis axes intersect or overlap.As be offset to p ', and show that then counter point device graduation circle and the crosshair of graticule I have departed from L on the x axle, on the y axle, departed from H, illustrated that the counter point device optical axis does not overlap (as Fig. 2) with the transit feathering axis.
4, at this moment,, correct the L/2 and the H/2 of side-play amount respectively, make p ' displacement p " with two final motion screws that control graticule 1 on the light socket moves.
5, after graticule I adjusts and finishes, see graticule II clearly with optical plummet again, repeat aforesaid operations.When graticule I, II all adjust finish after, at this moment the crosshair focus of graticule I, II is adjusted to the transit feathering axis.
