Abstract

The invention discloses a centering and leveling device for engineering surveying. The centering and leveling device comprises a mounting box. An adjusting mechanism is mounted at the top of the mounting box. A laser range finder is mounted on the adjusting mechanism. A distance measuring box is mounted at the bottom end of the mounting box. The center of the bottom end of the distance measuring box is hinged to one end of a supporting rod. The other end of the supporting rod is hinged to the center of the top of the leveling box. A water tank is arranged in the leveling box. The water tank isfixed at the inner bottom end of the leveling box through a mounting base, and a horizontal calibration mechanism is arranged between the leveling box and the mounting box. The device is convenient to use, high in horizontal calibration efficiency and accurate in distance measurement.

Description

technical field [0001] The invention relates to the technical field of engineering survey, in particular to a centering and leveling device for engineering survey. Background technique [0002] In engineering construction, the terrain is often inspected, and the most commonly used tool for measuring terrain is the level, which can measure the ground in all directions. However, due to the large size of the traditional level, it is troublesome to move, and it takes a long time to perform level calibration. When encountering uneven ground, it needs to be recalibrated after moving, which is very troublesome to use, and the distance measurement value is not accurate enough. [0003] Therefore, in view of the above current situation, it is urgent to develop a centering and leveling device for engineering measurement. Contents of the invention [0004] The object of the present invention is to provide a centering and leveling device for engineering survey, so as to solve the pro...
