Energy-absorbing buffering expressway protective fence
The invention relates to the technical field of protective fences. The invention aims to an energy-absorbing buffering expressway protective fence comprising a protective fence body which is arranged on the edge of a lane and extends in the length direction of the lane, and the protective fence body comprises a plurality of stand columns distributed at intervals and a protective fence body arranged on the stand columns; a first energy-absorbing buffer mechanism and a second energy-absorbing buffer mechanism arranged at two ends and the middle part of the oscillating rod; the second energy-absorption buffer mechanism comprises a fixed pile fixedly arranged on the outer side of the guardrail main body and a traction buffer assembly used for connecting the fixed pile and the swing rod; the traction buffer assembly comprises a first inhaul cable and a deformation pull rod. A traditional guardrail body collapse energy absorption mode is changed, step absorption of impact force is achieved in the rotating process of the swing rods, and the buffering performance is better.
本发明涉及防护栏技术领域。目的在于提供一种吸能缓冲高速公路防护栏,包括设置在车道边沿的沿车道长度方向延伸的防护栏，所述防护栏包括若干间隔分布的立柱和设置在立柱上的护栏主体；摆动杆的两端及中部分别设置有第一吸能缓冲机构和第二吸能缓冲机构；所述第二吸能缓冲机构包括固定设置在护栏主体外侧的固定桩以及用于连接固定桩与摆动杆的牵拉缓冲组件；所述牵拉缓冲组件包括第一拉索和变形拉杆。本发明改变了传统的护栏主体溃变吸能方式，在摆动杆旋转的过程中实现冲击力的梯级吸收，缓冲性能更好。
