The invention provides an integrated valve block for a hydraulic braking system of an empty-container stacking machine. The integrated valve block comprises a valve body and an energy accumulator, wherein an oil inlet communicated with the oil outlet of a braking pump, an oil return opening, an oil feeding opening of a cooling oil channel of a driving bridge, an oil feeding opening of a hydraulic pilot oil source, a parking-brake oil feeding opening and a running-brake oil feeding opening are formed in the valve body; one path of the oil inlet is connected with the oil return opening, the oil feeding opening of the cooling oil channel of the driving bridge, and a signal feedback port of a pressure reducing valve separately through a direct-acting overflow valve, and the outlet of the pressure reducing valve is communicated with the oil feeding opening of the hydraulic pilot oil source; another path of the oil inlet is connected with the running-brake oil feeding opening, the energy accumulator, a prefill valve, a two-position three-way electromagnetic valve and the pressure reducing valve separately through an one-way valve; the outlet of the prefill valve is connected with the two-position three-way electromagnetic valve; the outlet of the two-position three-way electromagnetic valve is communicated with the parking-brake oil feeding opening; the pressure reducing valve is communicated with the oil feeding opening of the hydraulic pilot oil source. The integrated valve block integrates five major functions, so that the arrangement of pipelines is reduced, the valve block is convenient to examine and maintain, and the cost is reduced.
