Problems solved by technology

After the vehicle collides with the guardrail in an accident, when the guardrail is difficult to protect, the vehicle will directly break through the guardrail, and the consequences are difficult to estimate. Especially for the poor protection ability of the bridge guardrail, the vehicle may directly break through the guardrail and fall into the bridge

Embodiment 1

[0040] see Figure 2-10 As shown, the flexible crash barrier system for cross-sea bridges includes:

[0041] The protective components 100 are arranged in a row;

[0042] The first railing 300 is used for connecting and fixing the protective components 100, and the airbag ejection group box 200 is installed on the first railing 300,

[0043] Wherein, the protective assembly 100 includes a cylinder 10, the cylinder 10 is sleeved with an inner box 20 that can rotate around the cylinder 10, the inner box 20 is surrounded by an outer box 30, and the box wall of the outer box 30 is ejected from the airbag through the rope body 220. The assembly 200 is connected, and the airbag ejection assembly 200 is activated to eject the airbag through the rotation of the outer case 30 .

[0044] The present invention implements the arrangement of guardrails along the road by arranging the protective components 100 in an array, and plays a protective role for passing vehicles. Connecting each...

Embodiment 2

[0057] see Figure 11 As shown, in this embodiment, the protective components 100 are arranged in a "W" row, and the protective components 100 are arranged at intervals. And utilize the first railing 300 to connect, can realize installing anti-collision guardrail along the road, realize reducing accident casualties.

Embodiment 3

[0059] see Figure 12 As shown, in this embodiment, the protective components 100 are arranged in an "X" shape; by arranging the protective components 100 at intervals. And utilize the first railing 300 to connect, can realize installing anti-collision guardrail along the road, realize reducing accident casualties.

Abstract

The invention discloses a flexible anti-collision guardrail system of a sea-crossing bridge, and belongs to the technical field of road safety protection. The flexible anti-collision guardrail system of the sea-crossing bridge comprises protection assemblies arranged in a whole column and a first handrail used for connecting and fixing the protection assemblies, wherein air sac ejection assemblies are installed on the first handrail, each protection assembly comprises a cylinder body, an inner box which can rotate around each cylinder body is connected with each cylinder body in sleeving mode, an outer box is arranged around the exterior of each inner box, the box wall of each outer box is connected with each air sac ejection assembly through a rope body, and the air sac ejection assemblies are started for ejecting air sacs by rotating the outer boxes. The flexible anti-collision guardrail system of the sea-crossing bridge can achieve a buffer function when a vehicle strikes a guardrail, achieves elastic collision between the vehicle and the bridge guardrail, and effectively reduces harm and loss which are caused by rigid collision to the vehicle and passengers.

Description

technical field [0001] The invention belongs to the technical field of road safety protection, and in particular relates to a flexible anti-collision guardrail system for cross-sea bridges. Background technique [0002] With the continuous development of economic construction, transportation is becoming increasingly busy. Traffic accidents occur most frequently on roads and bridges. In order to reduce the occurrence of traffic accidents, various guardrails are installed on both sides of the road and the bridge. Since the guardrails are made of iron structure and inelastic, the guardrails such as rigid guardrails have strong protection ability, but when the car collides with the guardrail , under the action of instantaneous impact load, the guardrail basically does not move or deform. The energy absorption in the collision cover process depends on the plastic deformation of the car itself, the second is the friction contact between the car and the guardrail, and the third is...
