Abstract
The invention discloses a theodolite calibrating installation. The calibrating installation includes a light source 1, an eyepiece micrometer device 2, a beam splitter prism 3, a 3 m reticle 4, a small reflector 5, a large reflector 6 and an objective lens 8; each member is fixed on a shell 14; the top end of the light source 1 is provided with a collimation reticle 13; the eyepiece micrometer device 2 is above the light source 1; the beam splitter prism 3 is installed on the eyepiece micrometer device 2; the 3 m reticle 4 is installed at the front end of the beam splitter prism 3; the small reflector 5 and the large reflector 6 are located on the right of the light source 1 and the eyepiece micrometer device 2, and are in parallel arrangement; the objective lens 8 is installed in the middle of the right side of the shell 14; a high collimator 7 and a low collimator 9 are respectively installed at the upper part and lower part of the right side of the shell 14; and the light horizontally passing through the objective lens 8 is a collimated light, and both the included angle between the high collimator 7 and the collimated light and the included angle between the low collimator 9 and the collimated light are 18 DEG.
Description
technical field [0001] The technology belongs to the verification device field, and in particular relates to a theodolite verification device. Background technique [0002] Theodolite is a precision instrument widely used in astronomy, geodetic and engineering surveys. It is mainly used in geodesy, meteorology, railways, highways, bridges, water conservancy, mining, construction, large-scale machinery manufacturing, installation and measurement work, and is also used in transportation or other large-scale models to accurately determine the orientation. As a measuring instrument, it can precisely measure angles and also measure large spatial dimensions. With the continuous development of production and technology, theodolite is playing an increasingly important role. [0003] The accuracy of the theodolite directly affects the accuracy of its measurement results. Therefore, it must undergo strict metrological verification before use, and the theodolite will produce certain ...
