The invention discloses a semi-automatic lifting early warning device for an open pit coal mine production command vehicle. The semi-automatic lifting early warning device comprises a carrier mechanism, a lifting mechanism and a warning mechanism. The carrier mechanism comprises a vehicle front driving part and a vehicle rear compartment part connected with the vehicle front driving part; the lifting mechanism comprises a base and a first threaded column which is in threaded connection with the interior of the vehicle rear compartment part and corresponds to the bottom of the base, a fixing rod is connected to the upper end of the base through a bolt, a lead screw is arranged in the fixing rod, a lifting rod in the spiral line trend is arranged at the top of the lead screw, and the lifting rod does telescopic motion on the lead screw; and a first threaded groove is formed in the top of the lifting rod. According to the invention, the early warning capability can be improved during early warning, the overall height can be reduced when the electric pressure telescopic rod is contracted, and the electric pressure telescopic rod can pass through a limited high point; and when stretching out, attention of a mining truck driver is drawn enough, and accidents of personnel in the disassembly and assembly process are avoided.
