The invention belongs to the technical field of storage, and relates to an intelligent storage industry, in particular to a centering platform for steel plates in the transferring process of the steelplates in a plate storage warehouse. The centering platform is mainly composed of the three parts of a main frame, centering clamping plates and centering mechanisms. A guide rail allowing the centering clamping plates to slide, the at least two sets of oppositely arranged centering clamping plates and the two sets of centering mechanisms are installed on the main frame, each set of centering clamping plates is composed of two push plates, and the centering mechanisms drive the centering clamping plates to relatively slide on the guide rail to be used for solving the sorting placement problemof the steel plates with different specifications in the transferring process. According to the centering platform for the steel plates, motor control is adopted, no hydraulic system is arranged, a tray structure is not adopted, the structure is simple, and the working efficiency is high; and the centering action is simple, the plate specifications are diverse, the adaptability is high, the requirements of the plates with the different specifications for superposition carrying can be met, the centering platform is suitable for intelligent development of a plate finished product warehouse, andthe warehouse labor cost is reduced.
