Safety anti-collision device for highway guardrail
The invention discloses a safety anti-collision device for a road guardrail. The safety anti-collision device comprises: a stand column, a guardrail which comprises a metal fixing plate arranged in awave shape, a buffer cushion layer and a protection mechanism, wherein the metal fixing plate is fixedly connected to the stand column, the buffer cushion layer is arranged on the surface, facing theroad, of the metal fixing plate, the protection mechanism comprises a protection layer which is a protection plate arranged outside the buffer cushion layer; the protective layer can slide along the grooves in the stand columns, a driving module which is connected to the protective layer; a control mechanism which comprises a distance measuring module and a control module, wherein the control module is connected with the driving module, when the distance measuring module detects that the distance between a running vehicle and the stand column is smaller than a preset first threshold value, a trigger control module controls the drive module to drive the protective layer to move downwards so that the buffer cushion layer can be exposed. It is guaranteed that the guardrail device has enough strength, the dynamic shearing force borne by a collided vehicle can be reduced to the maximum extent, and therefore the safety of passengers in the vehicle is protected to the maximum extent.
本发明公开了一种公路护栏安全防撞装置，包括：立柱；护栏，其包括呈波浪形设置的金属固定板、缓冲垫层以及保护机构；金属固定板固定连接于立柱；缓冲垫层设置于金属固定板朝向公路的表面；保护机构包括：保护层，其为设置于缓冲垫层外部的保护板；且保护层可沿立柱上的凹槽滑动；驱动模块，其连接于保护层；控制机构，其包括距离测量模块和控制模块；控制模块连接驱动模块；距离测量模块在检测到行驶车辆距离立柱间的距离小于预设的第一阈值时，触发控制模块控制驱动模块驱动保护层向下移动，以使缓冲垫层裸露。其既保证了护栏装置具有足够的强度，还能够最大限度的减小碰撞车辆受到的动态剪切力，从而最大程度的保护了车辆内乘员的安全。
