Shock absorption and noise reduction multidirectional displacement bridge expansion device

The utility model discloses a shock absorption and noise reduction multidirectional displacement bridge expansion device. The device comprises a first base pressing plate, a second base pressing plate, a first comb-shaped plate, a second comb-shaped plate and a water stop rubber belt, first comb teeth and second comb teeth are arranged on the first comb-shaped plate and the second comb-shaped plate respectively. The first comb teeth correspond to the second comb teeth, the first base pressing plate is matched with the first comb-shaped plate, and the matching structure formed by the second comb-shaped plate and the second base pressing plate is the same as the matching structure formed by the first comb-shaped plate and the first base pressing plate. The bridge shock absorber is tightly attached to the beam end while meeting bridge displacement and deflection, damage caused by load impact is reduced, meanwhile, the bridge shock absorber has good shock absorption performance, and the service life of a bridge c
