The high-tech measuring instrument is a surveying and mapping instrument system integrating the functions of horizontal angle, vertical angle, distance (oblique distance, horizontal distance), and height difference measurement. 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. Total stations are widely used in precision engineering measurement or deformation monitoring fields such as large-scale buildings on the ground and underground tunnel construction. The existing total station is usually set up on a tripod for use. Due to the unevenness of the ground, the total station usually needs to use a leveling device to level it before using it in the wind turbine foundation construction process. During the leveling process, it usually needs After two steps of preliminary leveling and precise leveling, the primary leveling is mainly by changing the height of the three legs of the tripod, so that the support plate on the top of the tripod is kept on a horizontal plane. When adjusting the length of the legs, it is necessary to first Loosen the locking bolts on the outriggers, and then manually adjust the height of the outriggers. When adjusting, the height of the outriggers is changed little by little based on experience. The adjustment efficiency is not high, and deviations are prone to occur; The height of the threaded rod, and then adjust the angle of the total station above, so that the total station is kept in a horizontal position. However, after the adjustment, the foot screw is exposed outside, and it is easy to touch the adjustment part during misoperation, resulting in the need for fine-tuning again. Waste of construction work time. Therefore, the present application provides a leveling device for wind turbine foundation construction.
