HEIGHT ADJUSTMENT SYSTEM OF STAFF FOR GEODETIC SURVEYING

摘要

The present invention relates to a height adjustment system of a staff for geodetic surveying, in which a horizontal adjustment means adjusts a staff coupler in a perpendicular direction to install the staff, coupled to the staff coupler, in a perpendicular state, a zero point adjustment means positions a zero point checking rod and a staff coupling unit coupled at an upper end of the zero point checking rod at a direct upper side in the perpendicular direction of the ground control point or each local point when a deviation between a zero point checking unit and the ground control point or each local point occurs in the process that a horizontal adjustment means adjusts the staff coupler in the perpendicular direction in a state that the zero point checking unit of the zero point checking rod is positioned at the direct upper side in the perpendicular direction of the ground control point or each local point as a landing rod lands on an inclined ground surface, to install the staff correctly at the direct upper side in the perpendicular direction with respect to the ground control point or each local point when a coupling protrusion coupled to a lower end of a lower staff is inserted and coupled into a coupling recess of the staff coupling unit, thereby enhancing precision in geodetic surveying, and the staff can be rapidly installed at the direct upper side in the perpendicular direction of the ground control point or each local point, thereby shortening a measurement time.;COPYRIGHT KIPO 2020
