According to the prefabricated bridge hoisting protection device and the using method thereof, before a bridge is hoisted, a first side frame, a second side frame and a bottom frame are placed on the three faces of the bridge, and connecting rods on the first side frame and the second side frame can be connected with hooks; during hoisting, the connecting rod can drive the first rotating frame and the second rotating frame to rotate through the steel wire rope, the first rotating frame can push out the extending rod, and therefore extrusion limiting of the first rubber pad is achieved, the movable base can be pulled along with movement of the steel wire rope, and the movable base can move along the guide base; when the movable seat moves, the telescopic rod can be driven to lift, and the telescopic rod can drive the second rubber pad to extrude and limit the bottom of the bridge, so that the bridge is supported, the load of the bridge is reduced, and the bridge is protected.
本申请公开了一种预制桥梁吊装防护装置及其使用方法，进行桥梁吊装前将第一侧架、第二侧架和底架放置在桥梁的三面，第一侧架和第二侧架上的连杆就可与挂钩相连，进行吊装时连杆就可通过钢丝绳带动第一转动架和第二转动架转动，第一转动架就可将伸杆推出，从而实现第一橡胶垫的挤压限定，随着钢丝绳的活动移动座就可被拉动，移动座就可沿着导座进行活动，移动座活动时就可带动伸缩杆进行抬升，伸缩杆就可带动第二橡胶垫对桥梁的底部进行挤压限定，从而实现对桥梁的支撑减轻其荷载，从而保护了桥梁。
