A high-precision and fast measuring target

Abstract

The invention provides a high-precision fast measuring target, which includes a precision positioning system, a precise leveling system and a precision centering system. The precise leveling system includes a support mechanism, a rotation mechanism and an alignment mechanism. The support mechanism includes a tripod bracket, a top seat It is connected with the base, the base is connected with the tripod bracket, the top base is connected with the base, the rotation mechanism is connected with the base, the alignment mechanism includes two tube levels, and the two tube levels are arranged perpendicular to each other, the precision centering system Including the centering mechanism, the centering mechanism includes a centering needle, a centering nut, a centering screw and a sandwich core, the centering needle and the centering screw are connected by a centering spring, the sandwich core is a four-leaf spring structure, and the sandwich sleeve It is arranged on the centering needle, the centering nut is threadedly connected with the centering screw rod, and the core is in conflict with the centering nut. The invention has the effects of faster erection speed, stronger adaptability, more convenient carrying, and higher reliability of observation and use.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a high-precision and rapid measurement target. Background technique [0002] The target refers to a frame set on a triangular point or a precise wire point for observation. It is made of wood, steel or other materials, in the shape of a triangular cone or quadrangular cone, with a height of several meters to tens of meters. The center of the sighting part is located on the vertical line of the triangular point or the wire point for sighting and observation elsewhere. [0003] Aiming at the problems of the target plate involving the large angle error introduced by the alignment error when measuring the short side angle, and the increase of the alignment error due to the relocation or transportation of the target plate, which is difficult to detect, a set of high-precision and rapid detection target standard is developed. . Compared with the currently used target plate,...
