Precision geometric leveling measurement vertical ruler righting device and operating method thereof

Abstract

The invention provides a precision geometric leveling measurement vertical ruler righting device and an operating method thereof. The righting device comprises a levelling staff fixed-connection unit, a liftable fixing-clamping connector and a telescopic support, wherein two ends of a fixed-connection rod on the levelling staff fixed-connection unit are respectively connected with a ruler fixed-connection clamp hoop, the liftable fixing-clamping connector comprises a clamping cylinder sleeving the fixed-connection rod and a transverse connection rod, and the transverse connection rod is connected with the telescopic support. The operating method of the righting device comprises a fixing device, an erecting device and a storage and carrying device for adjusting precision, collecting, moving and transferring are arranged on the levelling staff. The problem that leveling measurement vertical ruler righting is not stable and the levelling staff and a vertical ruler have inclination errors is solved, and precision transfer of the height difference between leveling line points is achieved.

Description

technical field [0001] The invention relates to the field of precision engineering measurement, in particular to a precision geometric level measuring straightening device and an operation method thereof. Background technique [0002] Precision leveling is a common method to achieve high-precision height transfer in the field of precision engineering surveying. △ ) is not more than 1 mm, and generally refers to the national second-class or above geometric leveling. Usually, a precision level is used to read the readings of the leveling staff erected at two points on the horizontal line of sight of the instrument, and measure the height difference between two points on the ground. [0003] In the actual field operation process, due to factors such as external temperature and wind force, the vertical support of the ruler is not enough, which makes the vertical ruler of the leveling rod unstable or there is a straightening deviation, resulting in the inclination of the levelin...

AI Technical Summary

Problems solved by technology

[0003] In the actual field operation process, due to factors such as external temperature and wind force, the vertical support of the ruler is not enough, which makes the vertical ruler of the leveling rod unstable or there is a straightening deviation, resulting in the inclination of the leveling rod at the moment of observation readings, resulting in observation inclination error

This error cannot be eliminated or discovered in time because of its small and insignificant difference in single-station inspection at any distance. However, in the implementation of long-distance precision engineering, as the number of stations increases, the tilt error accumulates. Make the reading on the leveling rod increase all the time, resulting in a tilt error in the measurement section or a round-trip discrepancy error that is too large or even exceeds the limit
