The invention discloses an intelligent arch bridge hanger rod replacement system, the replacement system includes a central control system; and a hydraulic pressing drive system, the central control system controls the working of the hydraulic pressing drive system; the replacement system also includes a tension oil cylinder device, the hydraulic pressing drive system provides hydraulic pressing oil for the tension oil cylinder device; and a monitoring component, which is connected with the central control system using communications, the monitoring component is used for monitoring the performance data of the arch bridge, and transfers the performance data to the central control system. The replacement system can achieve a nil step continual conversion of the two inner forces of the new and old hanger rods and a temp load bearing system, the displacement variation control is precise and the curved line is smooth, the replacement system has a full process of data acquisition automations, data analysis control intellectualizations and a displacement and force control precisions, and records and outputs the monitoring data files; the replacement system is suitably applied to hanger rod replacements under the state of bridge deck traffic passing through, the hydraulic pressing system constantly stabilizes pressure and compensates, acting as a damper for safeguarding the safety of bridge structure; and can be coupled with multiple units of equipments, and simultaneously replaces multiple pieces of hanger rods.
