Composite vibration reduction anti-collision guardrail
The invention relates to a composite vibration reduction anti-collision guardrail which comprises a guardrail body, a plurality of first vibration reduction mechanisms are fixed to the guardrail body, at least one second vibration reduction mechanism is arranged on each of the two sides of each first vibration reduction mechanism, each first vibration reduction mechanism comprises a first shell fixed to the guardrail body, and each first shell is elastically connected with an extrusion cover. The second vibration reduction mechanism comprises a second shell fixed to the guardrail body, a container is arranged in the second shell, an impeller and damping liquid are arranged in the container, the impeller is in threaded connection with a first connecting rod, and the first connecting rod penetrates through the container and the second shell and then is hinged to one end of a second connecting rod. The outer edges of blades of the impeller are connected with the container in a sliding mode, flexible plates are arranged between the adjacent extrusion covers, and the guardrail can achieve multiple vibration reduction and is suitable for vibration reduction and collision prevention of high-speed vehicles.
本发明涉及一种复合减振防撞护栏，包括护栏本体，护栏本体固定有多个第一减振机构，每个第一减振机构的两侧均设有至少一个第二减振机构，第一减振机构包括与护栏本体固定的第一外壳，第一外壳与挤压盖弹性连接，挤压盖与筒体之间设有惯容机构，第二减振机构包括固定在护栏本体的第二外壳，第二外壳内设有容器，容器内设有叶轮和阻尼液，叶轮与第一连杆螺纹连接，第一连杆穿过容器和第二外壳后与第二连杆的一端铰接，第二连杆的另一端与挤压盖铰接，叶轮的叶片外边缘与容器滑动连接，相邻挤压盖之间设有柔性板，本发明的护栏能够实现多重减振，适用于高速车辆的减振防撞。
