Bridge road collision-prevention device capable of slowing down side impact

Abstract

The invention relates to a bridge road safety protection device, in particular to a bridge road anti-collision device capable of slowing down side impact, comprising a casing and a baffle. There is a groove opposite to the baffle, and an elastic ball is arranged between the groove and the baffle. The casing is provided with a fixed seat on both sides of the groove, and a slot matched with the insertion rod is arranged in the fixed seat. The side of the fixed seat is provided with a through hole that communicates with the slot, an O-ring is provided at the contact between the insertion rod and the fixed seat, a shock-absorbing groove is provided on the shell, and a shock-absorbing pad is arranged in the shock-absorbing groove. There are oppositely arranged springs inside, and shock-absorbing blocks are arranged on the side of the casing, and the shock-absorbing blocks are connected by springs; the technical solution provided by the present invention can effectively overcome the existing technology that cannot effectively slow down the accident between vehicles and bridges. Defects in the impact force generated when a side impact occurs between the two.

Description

technical field [0001] The invention relates to a bridge road safety protection device, in particular to a bridge road anti-collision device capable of alleviating lateral impact. Background technique [0002] With the continuous improvement of our country's national economy, the transportation industry has also achieved considerable development. Especially in recent years, the number of cross-sea bridges has increased significantly. On the one hand, it has eased the increasingly busy traffic pressure and promoted the development of land transportation; but On the other hand, since the current anti-collision devices for bridges and roads are mainly guardrails, and the existing guardrails are very simple in structure, they are easily deformed after being hit by the accident vehicle, and cannot effectively slow down the impact force generated during lateral impact, which is likely to cause relatively Serious road traffic accidents, at the same time, part of the structure of th...
