Driving coordinate acquisition device for mine sandpit

The utility model relates to the field of coordinate acquisition, in particular to a driving coordinate acquisition device for a mine sandpit, which comprises an X-axis acquisition module and a Y-axis and Z-axis combined acquisition module, the X-axis acquisition module comprises guide rails fixed on the two sides of the sandpit and a walking assembly arranged on the guide rails in a sliding manner; the walking assembly comprises a shell, a wheel set which is rotationally arranged in the shell and rolls on the guide rail, and a first encoder arranged on the wheel set. The beneficial effects of the utility model are that during actual use, X-axis information is acquired through the X-axis acquisition module, Y-axis information and Z-axis information are acquired through the Y-axis and Z-axis combined acquisition module, so that a three-dimensional coordinate is formed through the X-axis information, the Y-axis information and the Z-axis information, the construction of a three-dimensional space model inside a
