Device and method for calibrating plumb aligner

Abstract

The invention discloses a device for calibrating a plumb aligner. An upright column is provided with a plumb aligner holding cabin and an operating platform which are connected with a laser mirror cabin through a supporting column; the laser mirror cabin is connected with a fine adjusting cabin through a supporting column; the fine adjusting cabin is provided with a rough adjusting head; and the rough adjusting head is provided with a plurality of rough adjusting bolts. The invention provides the device and a method for calibrating the plumb aligner, which are used for calibrating a sight axis and a laser optical axis by taking a vertical axis and a zenith / nadir sighting mark (or remote fixed sighting mark) of the plumb aligner calibrated by a water level as dynamic bench marks. In the calibration process, the calibrated plumb aligner always keeps the leveling state during use, the target seeking task is completely finished by the zenith / nadir sighting mark, and therefore, the influence of included target seeking of the plumb aligner in the traditional method on the indeterminacy of a calibration result is greatly reduced. In addition, fewer adjustment times, shorter adjustment time, higher correction precision and more convenience for operation are realized.

Description

technical field [0001] The invention relates to the field of plummet calibration, in particular to a device and method for calibrating a plummet. Background technique [0002] The website of Dalian Latch Laser Technology Development Co., Ltd. (www.latchina.com) discloses a standard device for indoor calibration of the plummet. on the platform. Its optical plummet calibration takes the collimator as the zenith and nadir infinite target; the laser plummet calibration uses multiple mirrors and photoelectric digital receiving targets to achieve limited distance calibration. The device is a four-in-one optical-mechanical-computer-calculator, and the calibration items are comprehensive. [0003] The disadvantage is that the calibrated optical plummet and the collimator are not in the direction of the plumb line, which deviates from the use state of the plummet, and the conversion error will inevitably be caused by using optical elements such as pentagonal prisms to bend the opti...
