Fabricated energy consumption type anti-falling beam device

The utility model belongs to the technical field of bridges, and particularly relates to an assembly type energy dissipation type anti-beam-falling device which comprises a pull rod. The energy dissipation assembly is arranged at the end of the pull rod and sequentially comprises a rubber buffering cushion, an inner base plate, a steel pipe damper, an outer base plate and interlocking double nuts in threaded connection to the tail end of the pull rod from inside to outside, and the pull rod is sleeved with the rubber buffering cushion, the inner base plate, the steel pipe damper and the outer base plate. The steel pipe damper is provided with a plurality of yield grooves, the yield grooves sequentially yield when a falling beam occurs, and the yield grooves are matched with the rubber buffer pad to act on the falling beam, so that the effect of buffering energy consumption can be achieved, and the falling beam is prevented from falling. And the steel pipe damper controls the yield force by controlling the mac
