Anti-collision protection fence for roads and bridges

Abstract

The invention belongs to the technical field of anti-collision protection fences, and particularly relates to an anti-collision protection fence for roads and bridges, which comprises protection devices evenly laid along a road. A buffering mechanism comprises a guardrail and two first hinge seats, the two first hinge seats are located on the left side and the right side of the rear portion of the upper end of the bottom plate, first cylinder bodies are hinged to the first hinge seats, first piston cylinders are arranged at the front ends of the first cylinder bodies, first pistons are slidably connected to the first piston cylinders in a sealed mode, and first piston rods are fixedly connected to the front ends of the first pistons. And the protection device comprises a bottom plate, and a buffer mechanism and a jacking mechanism are arranged at the upper end of the bottom plate. Through three-layer buffer protection, when a vehicle collides with the guardrail, impact force generated when the vehicle collides with the guardrail can be gradually dispersed and absorbed. Hard collision between the vehicle and the guardrail is avoided, so that damage to the vehicle is reduced, and protectiveness to people in the vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of anti-collision protection fences, and in particular relates to an anti-collision protection fence for road bridges. Background technique [0002] As an essential facility on highways and bridges, anti-collision protection barriers have a certain impact on high-speed driving safety, driving comfort, highway landscape and project cost. Good road and bridge anti-collision protection barriers have an Driving safety plays an important role, so a kind of anti-collision protection fence of road bridge is more and more required; A hard collision will cause great damage to the vehicle, and the protection of the occupants in the vehicle is insufficient. In view of the above problems, we have proposed a kind of anti-collision protection fence for road bridges. Contents of the invention [0003] The object of the present invention is to provide an anti-collision barrier for road bridges, which is used to solve the...
