Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, in particular to a centering rod rapid calibration device. Background Art

[0002] With the development of modern surveying and mapping science and technology, GPS-RTK technology is widely used in construction mapping and layout with its all-weather, high-precision, automated, and no need for line of sight for measuring points. It is used in conjunction with the centering rod. As a commonly used equipment in field surveying and mapping, the RTK centering rod should not be deformed and all buckles should function normally during field measurements in order to ensure the reliability of the measurement results. The most important thing is that its verticality must meet the standard. The verticality index of the centering rod is mainly represented by the centering of the bubble of the circular level on the rod body.

[0003] The existing centering rod rapid calibration device has low calibration efficiency during use, which affects the measurement efficiency. At the same time, it is inconvenient to fix the centering rod and has poor stability. Therefore, we propose a new type of centering rod rapid calibration device. Utility Model Content
