Highway protective fence capable of cushioning during collision
The invention discloses a highway protective fence capable of cushioning during collision, and belongs to the field of highway supporting facilities. The highway protective fence capable of cushioning during collision comprises a fence column shell, a flat handrail, a columnar block, a first cushioning mechanism and a second cushioning mechanism, the columnar block penetrates through the front wall of the fence column shell and is in sliding connection with the front wall of the fence column shell, the flat handrail is fixedly connected with the front end of the columnar block, the first cushioning mechanism is arranged on the upper side in the fence column shell, the second cushioning mechanism is arranged on the inner lower side of the fence column shell, the first cushioning mechanism comprises a piston assembly and an air valve assembly, a limiting ring is arranged in the middle of the inner wall of a air cylinder body, and a piston can be prevented from being extruded out of the air cylinder body when the air cylinder body is inflated; a communicating pipe is fixedly connected between the air cylinder body of the first cushioning mechanism and the air cylinder body of the second cushioning mechanism, the air pressure between the two air cylinder bodies is the same, the two pistons move backwards at the same speed when the air cylinder bodies are impacted, and damage can be reduced.
本发明公开了一种能够在撞击时缓震的公路防护栏，属于公路配套设施领域。一种能够在撞击时缓震的公路防护栏，包括栏柱外壳、平板栏杆、柱状块、一号缓震机构和二号缓震机构，柱状块贯穿栏柱外壳前壁并与栏柱外壳前壁滑动连接，平板栏杆固定连接于柱状块前端，一号缓震机构设于栏柱外壳内上侧，二号缓震机构设于栏柱外壳内下侧，一号缓震机构包括活塞组件和气阀组件，气缸体内壁中部设有限位环，能够在气缸体内充气时防止活塞被挤出气缸体，一号缓震机构和二号缓震机构的气缸体之间固定连接有连通管，使得两个气缸体之间的气压相同，在被撞击时，两个活塞以相同的速度向后运动，能够减少损坏。
