The invention belongs to the technical field of railway safety protection construction, and provides a railway concrete protective fence positioning and installation platform. The railway concrete protective fence positioning and installation platform comprises a support frame body, wherein four support legs are arranged at the bottom of the support frame body, an adjusting screw rod is arranged at the bottom of each support leg, and a foot-pad steel plate is arranged at the bottom of each adjusting screw rod. A longitudinal moving frame body is arranged above the support frame body, a transverse moving frame body is arranged above the longitudinal moving frame body, and upright column fixing fixtures and level bubbles are fixedly arranged above the transverse moving frame body. The support frame body is provided with longitudinal clamping grooves, four longitudinal moving walking wheels capable of walking along the longitudinal clamping grooves are arranged at the bottom of the longitudinal moving frame body, transverse clamping grooves are formed in the upper part of the longitudinal moving frame body, and four transverse moving walking wheels capable of walking along the transverse clamping grooves are arranged at the bottom of the transverse moving frame body. According to the railway concrete protective fence positioning and installation platform, the time required for positioning and fixing upright columns is greatly reduced, the operation is simple, the installation quality of protective fences is improved, and the popularization value is extremely extensive.
