Block is rushed by collision deformation, buffer stopper can be taken out from dashpot, individually replaced at this time, avoids replacing anticollision box,
Further decrease the cost that accident treatment is dealt with problems arising from an accident.
The utility model is further arranged to：Cellular stepped construction is equipped in the buffer stopper.
Stacked through the above technical solutions, the cross section of buffer stopper is a large amount of cellular hexagonal structures, by
To when hitting, crumple orderly equably occurs for hexagonal structure, can absorb the maximum amount of kinetic energy with minimal deformation, lead to
Preferable buffering effect can be played by crossing relatively thin buffer stopper.
The utility model is further arranged to：Spring base is threaded with by bolt assembly in the dashpot, it is described
Spring base is equipped with buffer spring, and the one end of the buffer spring far from spring base is connected on buffer stopper.
Through the above technical solutions, while buffer stopper is by crumple deformation is hit, buffer spring is squeezed into dashpot,
Buffer spring forced compression, absorbs impact force in a manner of elastically-deformable, is conducive to improve buffering effect.Pacified by bolt assembly
The spring base of dress is easy to dismount, and is conducive to improve the convenience for replacing buffer stopper.
The utility model is further arranged to：The bottom of the anticollision box is equipped with support leg, and one end of the support leg connects
It connects on the ground, the support leg is equipped with spring spool.
Through the above technical solutions, support leg plays a supportive role on ground in face of anticollision box, when anticollision box is impacted, vertically
The shock being subject on direction can be reduced subaerial influence attached on viaduct pier and be destroyed by the flexible of spring spool.
The utility model is further arranged to：The anticollision box lower box, which is equipped with, swings chamber, is equipped in the swing chamber
One end of buffering pendulum, the buffering pendulum is rotatably connected on swing top of chamber, and the buffering pendulum is swung along vertical anti-collision case direction, institute
It states buffering pendulum bottom and is equipped with pendulum.
Through the above technical solutions, when anticollision box is hit, kinetic energy is transmitted to anticollision box box house, and buffering pendulum is rushing
It is swung under the action of hitting, the impact force of horizontal direction is transmitted to tangential direction, it, can by the consumption kinetic energy that swings back and forth
The impact transmitted to viaduct pier is reduced, the effect for improving protection viaduct pier is conducive to.
The utility model is further arranged to：The swing intra-bladder instillation has buffer solution.
Through the above technical solutions, buffer solution uses sticky semifluid, when buffering pendulum is swung, buffer solution puts buffering
Larger resistance is generated, the entrained energy of buffering pendulum is to transform into thermal energy during buffer solution friction, by buffer solution
It absorbs, to further be effectively treated conversion to impact force.
The utility model is further arranged to：The flexible connector uses spring.
Through the above technical solutions, flexible connector using diameter it is thicker, the shorter spring of length, using spring cost compared with
It is low, at the same spring have the effect of it is good kinetic energy is transformed into elastic potential energy, be conducive to improve buffer strip absorb impact
Effect.
In conclusion the utility model has the advantages that：
1. by the deformation crumple of buffer stopper, buffer stopper can absorb a large amount of kinetic energy for hitting and generating, to pass through buffering
The damage of block exchanges the protection to viaduct pier for, can be effectively prevented Vehicular impact damage viaduct pier；
2. swinging intracavitary swing by buffering pendulum, potential energy is converted kinetic energy into, kinetic energy is further absorbed by buffer solution.
