Correction device and method of optical plummet of Leica base

Abstract

The invention discloses a correction device and method of an optical plummet of a Leica base. The device comprises a triangular base matched with an installation base platform and a base connector which is arranged on the triangular base in an inverted manner and is used for correcting the Leica base in an assisting and cooperative manner, wherein the triangular base is connected with the base connector through a connecting piece, and the Leica base is arranged at one end, far away from the triangular base, of the base connector in an inverted manner; the method comprises the following steps of firstly, installing a correction device of a Leica base optical plummet; secondly, setting a correction point; thirdly, adjusting a reticule of the optical plummet of the Leica base to coincide withthe reticule of a cross correction point on an auxiliary object; and fourthly, rotating the Leica base by 180 degrees, and observing whether the two reticules are overlapped again. The triangular base and the base connector are connected by manufacturing the connecting piece for connecting the same, and a rotatable function of the base connector is used for driving the non-rotatable Leica base with the optical plummet to rotate, thereby facilitating the correction of the Leica base without being limited by the environment.

Description

technical field [0001] The invention belongs to the technical field of calibration of a Lycra base aligner, and in particular relates to a calibration device and method for a Lycra base aligner. Background technique [0002] The Leica theodolite is mainly used in precision engineering survey fields such as high-precision deformation observation and geodetic control survey. On the pedestal, and the Leica pedestal itself cannot be rotated. At present, when correcting the Lycra pedestal, one is to install the Lycra pedestal on the theodolite, turn the Leica theodolite upside down and put it on the table, and draw a correction on the ceiling. point, move the Leica theodolite to make the crosshair of the plummet coincide with the correction point on the ceiling, and then use the rotating part of the Leica base and the theodolite to rotate the Leica base within 180°, and see the crosshair of the plummet on the Leica base Whether it coincides with the calibration point on the ceil...

[0002] The Leica theodolite is mainly used in precision engineering survey fields such as high-precision deformation observation and geodetic control survey. On the pedestal, and the Leica pedestal itself cannot be rotated. At present, when correcting the Lycra pedestal, one is to install the Lycra pedestal on the theodolite, turn the Leica theodolite upside down and put it on the table, and draw a correction on the ceiling. point, move the Leica theodolite to make the crosshair of the plummet coincide with the correction point on the ceiling, and then use the rotating part of the Leica base and the theodolite to rotate the Leica base within 180°, and see the crosshair of the plummet on the Leica base Whether it coincides with the calibration point on the ceiling, if it coincides, it means that the point aligner is qualified; in the process of turning the Leica base, because the Leica theodolite does not have a fixed device, it is just placed on the table, so it is unstable and moves back and forth, which is very It is difficult to calibrate accurately. If there is no coincidence, it needs to be calibrated repeatedly. When adjusting the transmission screw in the counter with the dial needle, because the Lycra base and the theodolite are not fixed, it will move back and forth, which is laborious and inaccurate to operate; Calibration of instruments and equipment needs to be repeated many times; in this way, if there is no special equipment for calibration, it will be difficult to calibrate the Leica base collimator, or even impossible to calibrate

The second is to send the Lycra base to the Surveying and Mapping Bureau, and use the multi-tooth indexing table dedicated to the Surveying and Mapping Bureau to calibrate the point counter on the Lycra base. The multi-tooth indexing table is expensive and not suitable for portable use in the field
