Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, in particular to an engineering measurement device for a circular rod axis. Background Art

[0002] The circular rod axis measuring device is a measuring and observation device used for the axis points at the ends of cylindrical rods in engineering surveying. The two symmetrical prism lenses installed on it are observed by a total station. After the observation values ​​are taken, the accurate coordinates of the axis endpoints are obtained. There is no need for manual hand-held prisms, which reduces measurement errors and improves measurement accuracy.

[0003] According to the search, the Chinese patent document, authorization announcement number CN208125117U, discloses a circular rod axis measuring device for engineering measurement. When the device is in use, the end of the circular rod is inserted between the arc-shaped outer frame and the connecting plate, and then the prism lenses are installed on both sides of the adapter. The prism lenses on both sides are observed by the total station to obtain the end coordinates of the circular rod and the coordinates of the bottom of the connecting plate, and then the axial length of the circular rod is calculated. The structure is simple and easy to operate, but the device cannot be adjusted according to circular rods of different diameters. Circular rods of different diameters will be involved in the engineering measurement process, and a single measuring device is only applicable to circular rods of a single diameter. Its scope of application is limited, which increases the measurement cost, so it is necessary to improve the existing device to meet actual needs. Utility Model Content
