Summary:The invention relates to a tail pushing device for a bridge body. The device comprises a supporting seat assembly mechanism, a pushing oil cylinder, a plug pin mechanism and a guide plate assembly. The tail pushing device for the bridge body is connected with a track beam which needs to be moved through the plug pin mechanism, and the pushing oil cylinder can extend and retract a cylinder body to push the bridge body or the track beam to move forwards. When the bridge body needs to be pushed to move forwards, a plug pin of the plug pin mechanism enters the track beam to enable the pushing device to be fixed, and then, the pushing oil cylinder extends the cylinder body so as to push the bridge body to move forwards; the plug pin of the plug pin mechanism is pulled out to enable the pushing device to be separated from the track beam; the pushing oil cylinder retracts the cylinder body, and the reacting force of the bridge body is used to reversely draw the pushing oil cylinder to move forward, so that processes
