Road and bridge safety crash barrier based on inertia principle
The invention relates to a road and bridge safety crash barrier based on an inertia principle. When a first protection frame is impacted by an external force to move towards a second protection frame;under an effect of inertia, an inertia vehicle is kept still relative to the ground; and when the second protection frame moves towards a right side, a pushing piece pushes a blocking piece into a groove through a first through hole equivalently, a first supporting plate is released, and under pushing of a first elastic piece, the first supporting plate pushes the protection device to extend outof the opening in the upper portion of the first protection frame and expand to form a buffer wall. Meanwhile, a first linkage plate is pushed by the first protection frame and enters a second containing cavity through a second through hole. And then a first shifting piece is pushed to enable a first rotating wheel to rotate anticlockwise, and a first mounting rod is driven by the first rotating wheel to rotate anticlockwise. The first mounting rod enables the supporting block to be separated from the bottom of the first blocking frame by pulling a steel cable so that the first blocking frameinclines towards the second protection frame and supports the side part of the second protection frame.
本申请涉及一种基于惯性原理的道路桥梁安全防撞栏，当第一防护架受到外力冲击朝向第二防护架移动时，在惯性作用下，惯性车保持相对于地面保持不动，而第二防护架朝向右侧移动，此时相当于推动件通过第一通孔向凹槽中推动阻挡件，第一支撑板被释放，在第一弹性件的推动下，第一支撑板推动防护装置从所第一防护架的上部开口伸出，并膨胀形成缓冲墙。同时，第一联动板被第一防护架推动并通过第二通孔进入第二容纳腔。然后推动第一拨动件使第一转轮逆时针旋转，在第一转轮的带动下第一安装杆也逆时针旋转。第一安装杆通过拉动钢索使得支撑块脱离使第一阻挡架的底部，使第一阻挡架朝向第二防护架倾斜并支撑第二防护架的侧部。
