Surveying instrument positioning equipment for engineering surveying and mapping and positioning method thereof

Abstract

The invention discloses surveying instrument positioning equipment for engineering surveying and a positioning method of the surveying instrument positioning equipment, and belongs to the field of engineering surveying, the surveying instrument positioning equipment comprises a supporting frame and an adjusting frame located in the supporting frame, and is characterized in that a center rod is arranged in the middle of the interior of the adjusting frame, a supporting plate is arranged at the top end of the center rod, and the supporting plate and the center rod are connected through a universal ball to rotate; transparent pipes in threaded connection with the supporting plate are symmetrically arranged on the outer wall of the supporting plate, a plurality of adjusting lead screws are annularly distributed in the adjusting frame with the center rod as the axis at equal intervals, a plurality of supporting shells are arranged at the bottom end of the supporting frame, the supporting shells and the supporting frame are rotationally connected through fixing bases, and supporting pieces are symmetrically arranged in the supporting shells. An adjusting block is arranged on one side of the supporting shell. While the surveying instrument is supported, the equipment can autonomously realize an axial positioning function and carry out horizontal positioning and vertical positioning, so that the positioning adjustment direction can be quickly determined by taking a supporting structure as a reference or taking a supporting surface structure as a reference.

Description

technical field [0001] The invention relates to the technical field of engineering surveying and mapping, in particular to a mapping instrument positioning device for engineering surveying and mapping. Background technique [0002] The total station, that is, the electronic total station (Electronic Total Station), is a high-tech measuring instrument integrating light, machinery and electricity. It is a set of horizontal angle, vertical angle, distance (slope distance, horizontal distance), A surveying and mapping instrument system integrating height difference measurement functions. Compared with the optical theodolite, the electronic theodolite replaces the optical dial with a photoelectric scanning dial, and replaces the manual optical micrometer reading with the automatic recording and display reading, which simplifies the angle measurement operation and avoids the occurrence of reading errors. Because it can complete all the survey work on the station once the instrume...

AI Technical Summary

Problems solved by technology

It is widely used in the field of precision engineering measurement or deformation monitoring such as large-scale buildings on the ground and underground tunnel construction, and is the main equipment for engineering surveying and mapping; when the total station is used, it is usually supported by a tripod to achieve a stable placement of the total station Once the total station is placed on the tripod, it will be time-consuming and laborious to change the height of the total station. The terrain and location of the surveying points are the ground without obstacles on the platform. If the surveying points are replaced, it will inevitably lose certain surveying accuracy, because the tripod structure is too simple, and it is difficult to ensure sufficient environmental tolerance and level. It is also difficult to provide positioning references, which will make the adjustment frequency of the surveying instrument more than that of the tripod, the functionality is insufficient, the surveying and mapping time is prolonged, and it is difficult to meet the needs of engineering surveying and mapping.
