Road and bridge fence protective guard structure

Abstract

The invention discloses a road and bridge fence protective guard structure. The structure comprises a plurality of buffer protective devices, and each buffer protective device comprises a protective main supporting seat and a buffer main plate. A first supporting seat groove is formed in one side of the protective main supporting seat, and a first lifting transverse plate, a first buffer mechanismand a second buffer mechanism are arranged in each first supporting seat groove; a first main plate slotted hole is formed in the upper part of each buffer main plate; a first moving column and a second moving column are connected into the middle part and the lower part of each buffer main plate; the first lifting transverse plates are clamped in the first main plate slotted holes, the first moving columns are connected with the first buffer mechanisms, and the second moving columns are connected with the second buffer mechanisms; second lifting plate grooves are formed in the first lifting transverse plates, first inner compression springs and buffering auxiliary plates are arranged in the second lifting plate grooves, and the buffering auxiliary plates are connected with the first lifting transverse plates through first limiting mechanisms. The road and bridge fence protective guard structure can perform multi-stage buffering, and is higher in safety, simpler and more novel in structure and high in innovativeness.

Description

technical field

[0001] The invention relates to the field of engineering machinery, in particular to a road and bridge fence structure. Background technique

[0002] With the gradual improvement of people's living standards, more and more families have cars. However, the incidence of car accidents is also increasing year by year. The light ones consume money, and the serious ones cause casualties, which destroys family happiness. Among them, on highways or bridges The fatality rate of traffic accidents in this location is the highest. If a car suddenly blows out while driving at high speed, the car will deviate from the route and crash into the guardrail. The safety guardrails of existing road bridges are mostly made of steel or cement, and the structural design is simple, only in the shape of columns connected with cross bars. In addition, the traditional guardrails are mainly rigid structures. Without the buffer force, the car will be subjected to a very strong reaction f...
