[0002] The bridge shock absorber is used to prevent the bridge from vibrating and to protect and maintain the stability of the bridge. Because the bridge itself has a natural frequency, when the vehicle above it is driven, it will bring downward pressure to the bridge itself, because the object will produce elasticity after deformation Momentum will make the bridge deck easy to vibrate. If the vibration is not stopped, it will directly cause the bridge to break, which will greatly reduce the service life of the bridge and cause the danger of bridge safety accidents. The existing bridge damping equipment installation It is inconvenient, and it is not convenient for large-scale installation. It can only be installed for individual bridge areas, which will reduce the practicability of the equipment. Effective shock absorption, which greatly reduces the reliability of equipment shock absorption

The invention discloses a bridge shock absorber. Bottom bridge base, a middle inner cavity penetrating left and right is formed in the bottom bridge base. Symmetrical bridge deck beams are arranged onthe upper end face of the middle inner cavity in an abutting mode. An open supporting inner cavity is formed in the bridge deck beam. A sliding plate is arranged in the middle inner cavity in a sliding manner; symmetrical side connecting plates are fixedly arranged on the end faces of the two sides of the sliding plate. A built-in hydraulic push cylinder is fixedly arranged in the side connectingplate; a top substrate is arranged on the upper side of the built-in hydraulic push cylinder in a power connection manner; the top substrate abuts against and supports the bridge floor beam. A pushing and supporting device for supporting and fixing the bridge floor beams on the two sides is arranged in the sliding plate; the equipment is simple in structure, the design of the pushing supporting device, the elastic supporting device and the variable-height supporting device is adopted, so that the equipment can stably support the bridge deck beam, the supporting stability and firmness of the equipment are improved through the multiple supporting devices, and the shock resistance of the equipment is further improved.
