TECHNICAL FIELD

[0001] The utility model relates to engineering surveying technical field especially relates to a leveling device of engineering surveying instrument. BACKGROUND

[0002] The leveling device of engineering surveying instrument is mainly used to ensure the level state of instrument in the use process to improve the measuring accuracy, and the traditional leveling mode depends on manual adjustment, and accurate level is realized through the adjustment of screw fine adjustment device, but there are problems such as complex operation and limited adjustment accuracy, therefore, research and development more efficient and convenient leveling device become the key to improve the measuring efficiency and accuracy.

[0003] However, in actual use, there are still the following deficiencies, for example: the leveling device of existing engineering surveying instrument cannot quickly and stably adjust the surveying instrument to the level state, for high-precision surveying instruments such as total station, when angle and distance measurement are carried out, the non-level of instrument will cause the deviation of vertical angle and horizontal angle of measurement, and then affect the accuracy of coordinate calculation and topographic survey, and the unstable leveling device can cause the slight inclination change of instrument in the measurement process, resulting in inconsistent measurement results, the instability of such data will bring difficulties to subsequent data processing and analysis, and it is difficult to determine accurate measurement value, thereby reducing the reliability of measurement data, when the leveling device cannot quickly and effectively adjust the instrument to the level state, the surveying personnel need to spend more time and energy to carry out leveling operation, which can cause the delay of the progress of the whole measurement work, especially in large-scale engineering projects, frequent measurement tasks are needed, and the extension of leveling time can seriously affect the work efficiency.
