Bidirectional multifunctional laser plumbing apparatus

Abstract

A kind of two-way multifunctional laser vertical collimator is made of bracket, zenith telescope module and nadir external laser telescope module, sphere vertical axis module and the triangular base. It is characterized in that: the zenith telescope module and nadir external laser telescope module are set on the A and B plane of main bracket top respectively, which are installed at the bracket orvertical axis center by the socket bolt and the column head bolt respectively. A phi 108 base hole is set below the main bracket, while, the outer of main bracket is set with a V-shape axile bush which is fixed the main bracket on the vertical axis module by a hole adjusting bolt to form a combination shafting which can rotate with the vertical axis; otherwise, a long level tube is installed on the side of main bracket which is used to adjust level and plumb.

Description

technical field [0001] The invention relates to a laser surveying and mapping instrument product, in particular to a two-way multifunctional laser plummet, which belongs to the category of optical instruments. Background technique [0002] The plummet is a kind of optical surveying instrument that uses the principle of collimation to provide a vertical alignment in the vertical direction, and is used to complete point, upper and lower vertical displacement (projection) measurements and horizontal deviation measurements relative to the plumb line. , it works see attached figure 2 . [0003] The instrument is at the origin of O, after centering, precise and stable orientation, and then rotated by the telescope, the center of the vertical axis of the instrument can be obtained at different heights by the average value of the two positions with a diameter of 180°, and the recorded coordinate position is the origin. The vertical point, the connecting line is the plumb line. Wi...

AI Technical Summary

Problems solved by technology

[0005] 1. It can only be used for vertical measurement in the direction of the zenith, and has a single function;

[0006] 2. Lower centering device 2~3 X The magnification, the centering accuracy is only ±1mm / 1500mm, which increases the error of the vertical measurement system, and it is difficult to improve the overall accuracy requirements of the vertical measurement;

[0007] 3. It can only perform one-way vertical alignment and short-distance alignment, so the longest distance of a vertical alignment measurement is also relatively short. The zenith laser plummet is 120-150 meters during the day and 250 meters at night;

[0008] 4. Due to the above-mentioned comprehensive reasons, the scope of use of the instrument is greatly limited, and the application range is not wide. For example: the zenith laser plummet cannot be used in the occasion where the ground point needs to be projected to the underground for a long distance; The quasi-measurement accuracy is not high, and it cannot be used in engineering measurement projects with high requirements, such as large-scale equipment, elevator installation, dam supervision, and deformation observation

[0009] With the sustainable development of my country's economy and urban construction, the types of engineering construction projects have increased, and the requirements for complexity, precision, and completion time have become higher and higher. Only one-way zenith laser plummets have been difficult to meet and meet. market user requirements
