The invention belongs to a sinking hoist control technique and provides movable high-voltage variable-frequency electric control equipment for a sinking hoist. The movable high-voltage variable-frequency electric control equipment comprises an electric control room and a control room both are closed hollow cubic members; the bottom of each of the electric control room and the control room is provided with a lug (13) allowing convenient hoisting and a cable passage (8) allowing passage of a power cable and a control cable; the electric control room allows the control cable to be connected with the power cable through the cable passage (8); a control cable exit in the electric control room is connected with a control cable in the control room through a quick connector, and independent hoisting and quick connection are achieved for the electric control room and the control room. The movable high-voltage variable-frequency electric control equipment is suitable for severe sinking sites and suitable for the condition of different supply voltages of high-voltage grids on different sinking sites.
