Description

Technical Field

[0001] The utility model relates to the field of engineering surveying and mapping, in particular to an engineering surveying and mapping laser surveying and mapping positioning device. Background Art

[0002] A total station, also known as a total station electronic distance meter, is a high-tech measuring instrument that integrates optics, mechanics and electronics. It is a surveying and mapping instrument system that integrates horizontal angle, vertical angle, distance (slant distance, horizontal distance) and height difference measurement functions.

[0003] To facilitate the rotation of the total station, the tray on which the total station is installed is connected in a rolling manner to the support rod. To facilitate limiting the position of the total station, a structure in which a clamping bolt directly cooperates with a threaded hole on the cylinder body is often used for pressure limiting. However, during the rotation of the clamping bolt, fine dust can easily enter the threaded hole with the clamping bolt, which not only increases the tightening resistance of the clamping bolt, but also makes it difficult to clean the dust in the threaded hole. Therefore, in view of the above problems, a laser surveying and positioning device for engineering surveying is proposed. Utility Model Content
