Problems solved by technology

Usually, the guardrails on both sides of the road or bridge are directly fixed. When the car accidentally collides with the guardrail, both the guardrail and the car are prone to damage, and the fixed guardrail has poor interception performance against the high-speed impact of the car. Car crashes off road and bridge

Abstract

The invention discloses an anti-collision device for a highway bridge, and relates to the field of highway bridge equipment. The anti-collision device includes a road slab, main buffering mechanisms and auxiliary buffering mechanisms, wherein multiple groups of the main buffering mechanisms are symmetrically arranged on the two sides of the road slab, the main buffering mechanisms include main buffering sleeves, main buffering shafts and fence supporting bars, multiple groups of the auxiliary buffering mechanisms are arranged on the upper surfaces of the fence supporting bars in the longitudinal direction, and the auxiliary buffering mechanisms include fence supporting columns, buffering telescopic rods and protective plates. According to the anti-collision device, in protection, the fencesupporting columns inclined outwards by impacting, the fence supporting bars are moved outwards of the road slab under dragging of the fence supporting columns, the main buffering shafts connected with the fence supporting bars are drawn out of pulling shaft sliding cavities formed in the main buffering sleeves, main pulling springs connected between the main buffering shafts and the inner partsof the pulling shaft sliding cavities are stretched, the main pulling springs can effectively buffer the impact force generated in car impacting, and a car can be effectively held up.

Description

technical field [0001] The invention relates to the field of highway bridge facilities, in particular to an anti-collision device for highway bridges. Background technique [0002] Guardrails are usually installed on both sides of the road or bridge to prevent the vehicle from deviating from the road or bridge during driving, especially for cars traveling at high speed on the bridge. Once the guardrail does not stop the car, the car will fall accidentally. Usually, the guardrails on both sides of the road or bridge are directly fixed. When the car accidentally collides with the guardrail, both the guardrail and the car are prone to damage, and the fixed guardrail has poor interception performance against the high-speed impact of the car. Accidents where cars ran off roads and bridges. Therefore, it is necessary to invent a kind of anti-collision device for highway bridge to solve the above problems. Contents of the invention [0003] The object of the present invention i...
