The utility model discloses a double amplification
energy consumption mechanism used between railway
pier beams and a railway, comprising a rotation amplification device, one end of which is arranged at the bottom of a main beam and the other end of which is arranged on a
pier; one end of the bridge-type amplifying device is connected with the rotary amplifying device, the other end of the bridge-type amplifying device is connected with a bridge
pier lug plate, and the end of the bridge pier lug plate is arranged on the bridge pier; the self-resetting
energy consumption damping device is arranged in the
bridge type amplifying device; the self-resetting energy dissipation damping device comprises a self-resetting
assembly and an energy dissipation
assembly, and the self-resetting
assembly and the energy dissipation assembly are of an integrated structure. According to the mechanism, through mutual cooperation of the rotation amplifying device, the
bridge type amplifying device and the self-resetting energy dissipation damping device, the energy dissipation capacity of a bridge structure is improved, the
relative displacement between a pier and a pier beam is reduced, structural resetting after an earthquake and
energy consumption in the earthquake are achieved through self-resetting energy dissipation, damage to components of a bridge main body structure is avoided, and the service life of the bridge is prolonged.
Damage control and post-earthquake function restorability of the bridge structure are achieved.
