Technical field
The utility model is related to field of traffic facilities, more particularly to a kind of viaduct pier anticollision barrier.
Background technology
With the development of society, the case where urban traffic blocking is increasingly severe, and the building in city is intensive, street
It is difficult to widen, in order to solve this problem, mostly uses overpass as traffic dispersion, overpass is usually above ground level more, leads to
It crosses and supports overhead bridge floor in ground setting bridge pier.It still needs to carry the larger magnitude of traffic flow, bridge simultaneously on road surface below overpass
Pier is difficult to avoid that the shock that may suffer from errant vehicle on the ground.
Currently, the Chinese invention patent that publication No. is CN107513954A discloses a kind of overpass with collision prevention function
Beam, it includes bridge floor, bridge pier and anticollision mechanism, and anticollision mechanism is arranged on the outside of bridge pier, and anticollision mechanism includes that shell and setting exist
Crashworthy plate, detection components, PLC on shell and air bag component, detection components include fixed block, first walk block, second walk
Block, spring, the first contact block, the second contact block, third contact block and the 4th contact block, air bag component include main gasbag, air pump and compression group
Part.
Although this elevated bridge can absorb certain shock dynamics in automobile impacting bridge pier, in the mistake for bearing to hit
Cheng Zhong needs the inflation that air bag is controlled by the signal of PLC, when the case where contact block generation poor contact, it is possible to lead to air bag
It cannot open, anti-collision effect can not be effectively acted as.
Utility model content
The purpose of this utility model is to provide a kind of viaduct pier anticollision barrier, its advantage is that can effectively act as
Prevent the effect of Vehicular impact damage viaduct pier.
The above-mentioned technical purpose of the utility model technical scheme is that:A kind of viaduct pier use

In the buffer stopper for absorbing impact.
Through the above technical solutions, when errant vehicle hits viaduct pier, buffer strip vehicle and viaduct pier it
Between work as a buffer.Vehicle hits buffer stopper first, and buffer stopper, by kinetic energy absorption, is not necessarily to additional electronics by way of deformation
Component triggers, reliable and stable, can effectively act as the effect for preventing Vehicular impact damage viaduct pier.In the mistake of shock
Cheng Zhong, each anticollision box abutted originally mutually disperse under the action of impact force, and tensile-elasticity connector, elastic force connector is being drawn
The kinetic energy of Vehicular impact is further absorbed during rising, while maintaining the integrality of buffer strip.In addition, after accident, directly
Connecing the anticollision box for bearing Vehicular impact and damaging can be individually replaced, and without whole buffer strip is needed to change, advantageously reduce at accident
The cost of reason.
The utility model is further arranged to:The anticollision box has dug dashpot away from the side of viaduct pier, institute
It states buffer stopper and fills out and be located in dashpot.
Through the above technical solutions, buffer stopper is filled in dashpot, in the case of minor impact accident, only delay
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.
