Safe, energy-absorbing and rollover-reducing road guardrail
The invention provides a safe, energy-absorbing and rollover-reducing road guardrail, and relates to the technical field of engineering construction. The safe energy-absorbing rollover-reducing highway guardrail comprises a fixed transverse plate, fixed connecting plates are slidably connected to the two ends of the upper end of the fixed transverse plate, guardrail stand columns are fixedly connected to the upper surfaces of the two fixed connecting plates, and clamping grooves are formed in the upper end and the lower end of one side of each guardrail stand column. A fixed transverse plate is pushed through a guardrail stand column, the fixed transverse plate slides at the upper end of a mounting base, a disc extrudes a spring while the fixed transverse plate slides, so that a part of collision force is counteracted again, and meanwhile, the guardrail stand column pushes the fixed transverse plate to slide and pushes an insertion plate to move towards a fixed vertical plate; the inserting plate can drive a limiting gear to rotate in the moving process, the limiting gear drives a second rotating shaft and a supporting column to rotate, and therefore the supporting column is inserted into a clamping groove in one side of the guardrail stand column and abuts against the guardrail stand column, and the protection effect is achieved.
本发明提供一种安全吸能降低侧翻公路护栏，涉及工程建设技术领域。该安全吸能降低侧翻公路护栏，包括包括固定横版，所述固定横版上端两端均滑动连接有固定连接板，两组所述固定连接板上表面均固定连接有护栏立柱，所述护栏立柱一侧上下端均设置有卡槽。通过通过护栏立柱推动固定横版，使固定横版在安装底座上端滑动，固定横版滑动的同时圆盘会挤压弹簧，从而再次抵消一部分碰撞力，同时护栏立柱推动固定横版滑动的同时推动插板向固定竖板移动，插板移动的过程会带动限位齿轮转动，限位齿轮带动第二转轴和支撑柱转动，从而使支撑柱插入护栏立柱一侧的卡槽内部，从而顶住护栏立柱，从而起到防护作用。
