The invention provides an anti-seismic device for reinforcing an old bridge. The device comprises a check block fixing system and an energy dissipation and seismic mitigation system, the check block fixing system comprises fixing plates and bolts, the fixing plates are arranged on the three side faces of an anti-falling beam check block, and the fixing plates are fixedly connected to the anti-falling beam check block in a manner that the bolts are inserted into the anti-falling beam check block; the energy dissipation and seismic mitigation system is located between the anti-falling beam checkblock and a main beam and comprises two energy dissipation plates, two elastic thin plates, four stiffening plates and four sealing plates, the two energy dissipation plates are arranged in a crossedmanner, the cross sections, in the direction perpendicular to the length direction of the main beam, of the two energy dissipation plates are of an X-shaped structure, and the side, right opposite tothe main beam, of the X-sh
