Embodiment Construction

[0020] In the first step, first loosen the measuring plate fixing screw of the measuring instrument, and pull the measuring plate out of the supporting and fixing slide groove plate.

[0021] The second step is to hold the measuring board in one hand according to the height of the measuring point from the ground, and the other hand to hold the measuring board fixing screw, so that the measuring board is roughly perpendicular to the supporting fixed slide groove plate, and the measuring board Roughly level (circular level bubble in the center), tighten the measuring plate fixing screw.

[0022] The third step is to open the right-angle auxiliary support plate, rotate it, and adjust the lifting micro-motion screw of the measuring plate to center the bubble of the vial even if the measuring plate is accurately level.

[0023] The fourth step is to fix the end point of the steel tape measure to the lower edge of the measuring board, and put the steel tape measure into any narrow groove o...

Abstract

A measuring instrument capable of accurately measuring heights of a theodolite, a total station, a reflecting prism, a GPS base station, targets, and the like is disclosed. The measuring instrument includes a measuring plate (including three parts which are a datum plate, a datum auxiliary plate and a datum ruler), a support fixed slide slot plate, a circular level, a level tube, a measuring plate fixing sleeve, a fixing screw, a measuring plate lifting and descending fine-motion screw, a right-angle auxiliary support plate, and the like. According to the measuring instrument, the measuring plate is horizontally put on a measuring station point (a control point, a level point, a GPS datum point, and the like), and then the height of an instrument, a prism, a target, and the like are accurately measured by virtue of a plumb bob and a steel tape. The measuring instrument can be widely used in the surveying and mapping industry, the industrial equipment installing industry, the building industry, the hydraulic engineering industry, the decoration industry, and the like, and has advantages of simple and convenient operation, high adaptability, few external interferences, and the like.

Description

Technical field: [0001] The invention belongs to an instrument that can measure height vertically. A measuring instrument that can accurately measure theodolite, total station, reflecting prism, GPS reference station and target elevation. Background technique: [0002] Theodolite, total station and GPS are the main instruments for survey work. When measuring the elevation of a ground point, it is often impossible to obtain more accurate results like a leveling instrument and leveling measurement. The main reason is that the height of the theodolite, total station, GPS base station antenna, prism and target cannot be accurately measured. If you want to use theodolite, total station, and GPS to accurately measure the height of a ground point, you must be able to accurately obtain the height of the instrument, prism, and target. Therefore, this is the inventive idea and purpose of the present invention. Summary of the invention: [0003] In order to get the height of theodolite, ...
