Abstract

The utility model discloses a lifting module and an on-site material level simulation device, and belongs to the technical field of material level measurement. The lifting module comprises a rack, a lifting mechanism and a rack leveling assembly, the rack comprises a base and a stand column, and the stand column extends in the vertical direction and is fixed to the base; the lifting mechanism comprises a lifting driving assembly and a lifting platform, the lifting platform is installed on the stand column in a liftable mode, and the lifting driving assembly is used for driving the lifting platform to ascend and descend. The rack leveling assembly comprises a fixing piece and a lifting supporting piece, the fixing piece is fixed to the base, the lifting supporting piece is in threaded connection with the fixing piece and extends in the vertical direction, and the bottom of the lifting supporting piece can abut against the containing face of the base; the at least three rack leveling assemblies are evenly arranged at intervals and used for adjusting the horizontal posture of the base so that the whole lifting module can be kept in the horizontal state. The lifting module is applied to the on-site material level simulation device, overall leveling of the on-site material level simulation device can be achieved, and on-site in-situ calibration precision is improved.
