Safety guardrail for highway construction
The present invention relates to a safety guardrail for highway construction. The safety guardrail comprises a rectangular frame and a steel wire net arranged on the front side of the frame, a plurality of buffering assemblies are horizontally and evenly distributed on the frame, and each buffering assembly is formed by universally hinging two rollers which are coaxially arranged up and down; a plurality of guide rods in one-to-one correspondence with the buffering assemblies are arranged on the frame, the upper ends of the guide rods are vertically connected with the frame in a sliding mode and connected with the frame through first springs, the guide rods slide upwards under the elastic force of the first springs, and the lower ends of the guide rods are universally hinged to the upper ends of the buffering assemblies; a plurality of positioning rods in one-to-one correspondence with the buffering assemblies are arranged on the frame, the lower ends of the positioning rods are rotationally connected with the frame, and the upper ends of the positioning rods are universally hinged to the lower ends of the buffering assemblies. Impact force in all directions can be effectively decomposed, buffered and resisted in a multiple mode, the protection effectiveness is greatly improved, the overall service life of the guardrail is prolonged, the guardrail can be recycled, and unnecessary material and labor cost is reduced.
本发明涉及一种公路施工用安全护栏，包括矩形框架和置于框架前侧的钢丝网，所述的框架上有水平均布的多个缓冲组件，缓冲组件由上下同轴设置的两个滚筒万向铰接组成；所述的框架上有置于与缓冲组件一一对应的多个导杆，导杆的上端与框架竖向滑动连接并经第一弹簧连接，导杆在第一弹簧的弹力下向上滑动，导杆的下端与缓冲组件的上端万向铰接；框架上有与缓冲组件一一对应的多个定位杆，定位杆的下端与框架转动连接，定位杆的上端与缓冲组件的下端万向铰接；本发明可将各个方向的冲击力进行多重有效的分解、缓冲和抵挡，使得防护有效性大大提高，并提高了护栏的整体使用寿命，可进行循环使用，减少了不必要的物料与人工成本。
