Foldable retarding device at end part of anti-collision guardrail
The invention relates to the technical field of vehicle traffic and particularly relates to a foldable retarding device at an end of an anti-collision guardrail. The guardrail comprises a ground rail,a plurality of guardrail railings, X-shaped supporting rods and guardrail cross rods, wherein the guardrail railing comprises an upper handrail with the hollow interior, a lower handrail with the hollow interior, an extension spring, an upper pulley, a lower pulley and an inserting device, the upper handrail is arranged on the upper side of the lower handrail, an upper connecting block is arranged at a top end in the upper handrail, a lower connecting block is arranged at a bottom end in the lower handrail, an upper end of the extension spring is fixedly connected with the upper connecting block, a lower end of the extension spring is fixedly connected with the lower connecting block, the upper pulley is arranged at a top end of the upper handrail, the lower pulley is arranged at the bottom of the lower handrail, and the inserting device is arranged between the upper handrail and the lower handrail. The guardrail is advantaged in that when ends are impacted, the upper guardrail and the lower guardrail are separated after guardrails are stressed, the X-shaped supporting rods deform to generate resistance under the action of stretching and elastic force of the extension springs, then resistance is reflected in backward movement of the guardrails, and therefore a purpose of retarding the vehicle speed is achieved.
本发明涉及车辆交通技术领域，具体地说就是一种防撞护栏端部折叠式缓速装置，包括地轨、若干护栏栏杆、X形支杆和护栏横杆，护栏栏杆包括内部中空的上栏杆、内部中空的下栏杆、拉伸弹簧、上滑轮、下滑轮和插接装置，上栏杆设在下栏杆的上侧，上栏杆的内部顶端设有上连接块，下栏杆的内部底端设有下连接块，拉伸弹簧的上端固连在上连接块上，拉伸弹簧的下端固连在下连接块上，上滑轮设在上栏杆的顶端，下滑轮设在下栏杆的底部，插接装置设在上栏杆与下栏杆之间，本装置的端部在受到冲撞时，各护栏栏杆受力后上栏杆与下栏杆分离，拉伸弹簧张开，弹力作用下使X形支杆的变形产生阻力，进而阻力体现在护栏栏杆的向后移动，从而达到减缓车速的目的。
