Buffering energy dissipation structure and beam falling prevention device

The utility model discloses a buffering energy dissipation structure and a beam falling prevention device, and belongs to the technical field of bridge engineering. The damping device is composed of a pressing block, a first damping element... an Nth damping element, a limiting cushion block and a supporting plate. Under the action of pressure generated when the pressing block is tensioned by the inhaul cable, buffering and energy reduction are achieved through elastic deformation of the multiple stacked damping elements; after being deformed, the damping elements are easily attached to each other and generate sliding friction to consume energy; when the deformation exceeds a certain displacement, the damping element generates plastic deformation, and the impact energy is further absorbed. The anti-falling beam device adopting the structure not only realizes dual energy consumption through elastic-plastic deformation and sliding friction of the damping piece, is high in energy consumption capacity, but also h
