The invention relates to a hydraulic synchronous control device and a control method thereof, provides a parallel hydraulic system based on a synchronous shunt motor and a control valve block, and aims to realize output control of equal-volume oil quantity at the same time point and equal hydraulic output values so as to achieve the design purpose of driving a mechanical structure to synchronously act. The hydraulic synchronous control device comprises a hydraulic station, and a jacking oil cylinder and a rail changing oil cylinder which are respectively communicated with the hydraulic station. A control valve group, a synchronous shunting motor and a synchronous valve group are connected among the jacking oil cylinder, the rail changing oil cylinder and the hydraulic station; the hydraulic synchronous control device is provided with n groups (n is greater than or equal to 2) of jacking oil cylinders, rod cavities of all the jacking oil cylinders are connected in series, and rodless cavities of all the jacking oil cylinders are connected in parallel; the hydraulic synchronous control device is provided with n groups (n > = 2) of rail changing oil cylinders, rod cavities of all the rail changing oil cylinders are connected in series, and rodless cavities of all the rail changing oil cylinders are connected in parallel.
