Problems solved by technology

In order to ensure the measurement accuracy, the center of the prism group is required to be plumb to the ground point. However, due to various factors in the actual use process, the center of the prism group and the ground point are not plumb, so it is necessary to correct the round blister, but the normal accuracy of the round blister Poor, resulting in a decline in surveying and mapping accuracy, unable to meet the needs of use

Abstract

The invention discloses a high-precision engineering-measurement centering rod device. The high-precision engineering-measurement centering rod device comprises a centering rod, a limiting device, a detachable conical head arranged at the bottom end of the centering rod, a water level assembly fixedly connected on the centering rod, a left supporting assembly and a right supporting assembly, wherein the left supporting assembly and the right supporting assembly are symmetrically arranged on the two sides of the centering rod; a left connecting rod and a right connecting rod are fixedly connected with the top end of an F-shaped support separately, and the F-shaped support is fixedly connected with the centering rod; a fine adjustment assembly and a fast adjustment assembly which are capableof adjusting the length of the left supporting assembly and the length of the right supporting assembly are also arranged on the left supporting assembly and the right supporting assembly respectively; the water level assembly comprises a right pipe water level and a left pipe water level which are perpendicular to each other, and the two side edges of the limiting device are in contact cooperation with the left connecting rod and the right connecting rod respectively so that the left connecting rod and the right connecting rod can be parallel to the right pipe water level and the left pipe water level respectively. By means of the high-precision engineering-measurement centering rod device, the measurement precision of the centering rod can be effectively increased, adjustment of the water levels can be achieved through the fine adjustment assembly and the fast adjustment assembly, and different using requirements are met.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping equipment, in particular to a centering rod device for high-precision engineering survey. Background technique [0002] As an indispensable centering device in surveying and mapping, the surveying and mapping centering rod has a wide range of uses in surveying and mapping. At present, when the existing centering rod is working, the lower end of the centering rod is used to align the tip of the centering rod with the target point to be measured, and the two support rods are adjusted to center the round blister. The prism group is plumb with the underground target point. In order to ensure the measurement accuracy, the center of the prism group is required to be plumb to the ground point. However, due to various factors in the actual use process, the center of the prism group and the ground point are not plumb, so it is necessary to correct the round blister, but the normal accuracy o...
