The invention provides an intelligent tri-fork stacking machine, and relates to the technical field of stacking machines. The machine structurally comprises an upper guide rail, a lower guide rail, amain body frame, a goods bearing platform, fork mechanisms, a horizontal running mechanism, a lifting running mechanism and an electric control cabinet, wherein the main body frame is horizontally glidingly mounted between the upper guide rail and the lower guide rail; the goods bearing platform is vertically glidingly mounted on the main body frame; three forks mechanisms are distributed on the goods bearing platform; the horizontal running mechanism is arranged at the bottom part of the main body frame and is used for driving the main body frame to horizontally move; the lifting running mechanism is arranged at one side of the main body frame and is used for driving the goods bearing platform to lift; and the fork mechanisms, the horizontal running mechanism and the lifting running mechanism are controlled through the electric control cabinet. The machine has the beneficial effects that the working efficiency of an automatic three-dimensional storehouse can be improved; and the one-time picking and warehousing efficiency of the stacking machine is three times the single-fork warehousing efficiency; and meanwhile, the energy consumption and the labor consumption are decreased; andmoreover, the space of the automatic three-dimensional storehouse can be fully utilized.
