Technical field

The invention relates to the technical field of surveying and mapping devices, specifically an adjustable surveying and mapping stand and a surveying and mapping device based on digital technology.

Background technique

Surveying and mapping instruments are measurement and testing tools that need to be used in land surveying and mapping. Simply put, surveying and mapping instruments are instruments and devices designed and manufactured for data collection, processing, and output for surveying and mapping operations. They are carried out during the planning, design, construction, and operation and management phases of project construction. Various orientation, distance measurement, angle measurement, height measurement, mapping and photogrammetry instruments required for surveying work;

Chinese Patent Publication No. CN217762905U discloses an adjustable surveying and mapping bracket, which includes a bracket. A partition is fixedly connected between both sides of the inner wall of the bracket. The interior of the bracket is divided into two storage chambers by the partition. A first permanent magnet is fixedly connected to the bottom of the partition, and a movable block is movably connected between both sides of the inner wall of the bracket and located at the bottom of the partition. The utility model moves the guide ring up and down and cooperates with the connecting rod to drive the support legs to fold or unfold, and indirectly drives the telescopic frame to move up and down through the rotation of the rotating handle, thereby realizing the elongation or contraction of the telescopic frame. When the surveying and mapping bracket is not needed, the utility model can The telescopic frame moves to the inside of the storage cavity, folds the support legs and then moves the inside of the storage cavity. The attraction of the first permanent magnet and the second permanent magnet adsorbs and fixes the support legs, so that the support legs are stored inside the storage cavity, which can reduce the energy consumption. The small volume between surveying and mapping brackets makes it easier for users to carry, improving the convenience of carrying surveying and mapping brackets;

Most of the existing surveying and mapping stands require manual operation to adjust the height. However, during manual operation, it is impossible to observe whether the height is appropriate through the surveying and plotting instrument, and the surveying and mapping stands are often used in uneven places.
