Forced total station centering device used for measuring track datum point of high-speed railway
The invention relates to a forced total station centering device used for measuring a track datum point of a high-speed railway. A total station has to be installed at the track datum point in track datum point plane arrangement, and the center of the total station is required to be strictly aligned to the track datum point. The forced total station centering device comprises a levelling bearing platform and a triangular support frame; the levelling bearing platform comprises a sleeve seat and an alignment plate arranged on the top face of the sleeve seat, and a horizontal total station base is fixed to the top face of the alignment plate through support columns; alignment bolts are arranged on the side face of the alignment plate; center shaft holes are arranged in the alignment plate and the sleeve seat, and a centering rod is arranged in the holes; the top end of the centering rod is a centering cone while the bottom end is a positioning cone; the triangular support frame comprises two horizontal large support arms which are fixed to the bottom surface of the sleeve base and form an acute angle, and a connecting strip is connected with the two large support arms; upright support rods are arranged at the other ends of the large support arms, and a support rod adjusting knob is arranged on each support rod. The forced total station centering device is reasonable in structure, easy to use and reliable in centering and provides fundamental guarantee to accurate measurement of the total station.
