HEIGHT ADJUSTMENT APPARATUS FOR BENCH MARK SURVEYING OF UNIFIED CONTROL POINT AND TRIANGULATION POINT

摘要

The present invention relates to a height adjustment device for surveying the level of unified control point and national bench mark. The present invention comprises a top support; three legs having the top coupled to the top support to be rotated so that it can be spread and pursed; an equipment mount coupled to the top support to mount survey equipment; an inclination detection unit installed in the equipment mount to detect the inclination of the equipment mount; an equipment mount horizontality maintaining unit for allowing the equipment mount to automatically maintain a horizontal state according to the inclination detection signal of the inclination detection unit; a control part embedded in a control box mounted on the underside of the top support; and a power supply unit for supplying power to the inclination detection unit, the equipment mount horizontality maintaining unit, and the control part. If the surveying equipment is mounted on the equipment mount after a tripod is installed at a time when the horizontality of the top surface of the equipment mount is automatically maintained by the equipment mount horizontality maintaining unit by spreading and landing the legs on the ground, the horizontality of the surveying equipment is maintained and the height adjustment of the equipment mount is quickly and conveniently performed; thereby quickly and efficiently performing the surveying work.
