Description

Technical Field

[0001] The utility model relates to the technical field of geological surveying and mapping, in particular to an adjustable surveying and mapping instrument for complex terrain. Background Art

[0002] Geological surveying and mapping is the general term for all surveying and mapping work involved in geological investigations and mineral explorations and the compilation of their results maps, and surveying instruments are instruments and devices designed and manufactured for surveying and mapping operations for data collection, processing, and output.

[0003] When using existing geological surveying instruments, it is necessary to select a surveying location according to the terrain. If the surveying location is not suitable for placing the surveying instrument, only a nearby location can be selected for measurement. However, this method of surveying will result in insufficient surveying accuracy, and once it is impossible to find a similar nearby point for surveying, the surveying will be impossible.

[0004] Therefore, in view of the above-mentioned problems, the present technical solution proposes an adjustable surveying and mapping instrument for complex terrain. Utility Model Content

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: By arranging three groups of adjustable positioning brackets in a triangular distribution at the bottom of the base, and using the positioning wheel sets at the bottom of the adjustable positioning brackets, it can be in controllable contact positioning with different terrains, ensuring that the surveying instrument body can perform stable surveying on different terrains. At the same time, by adjusting the length of the telescopic connecting rod, the swing connection between the swing connecting column and the U-shaped connecting frame, and the rotary connection between the rotary connecting rod and the connecting frame, the flexibility and adjustability of the adjustable positioning brackets are further increased, fully expanding the applicable range of this surveying instrument.
