Anti-collision guardrail for expressway
The invention discloses an anti-collision guardrail for an expressway, which comprises a first supporting column, a second supporting column, a first protective device and a second protective device,wherein the first protective device and the second protective device are arranged between the supporting columns; the first protective device comprises a fixed block, a sleeve, a buffer spring, an ejector rod and a first buffer block; the first buffer block is arranged at the right end of the sleeve; the right side wall of the first buffer block is fixedly connected to the left side wall of the second supporting column; the second protective device sequentially comprises a second buffer block, a supporting rod, a supporting spring and a guardrail body from left to right; and a protective layeris arranged on the right surface of the guardrail body. According to the invention, the first protective device and the second protective device are arranged on the supporting columns; the double protection devices can improve the buffering performance of the anti-collision guardrail on vehicles, so that the guardrail body can always protect the two sides of a road, reliable protection is formedfor passing vehicles, the vehicles are prevented from rushing out of the road surface, and the driving safety is improved. The anti-collision guardrail is simple in structure, low in cost and suitablefor application and popularization.
本发明公开了一种高速公路防撞护栏，包括第一支柱、第二支柱、以及设置在支柱之间的第一防护装置、第二防护装置，第一防护装置包括固定块、套管、缓冲弹簧、顶杆、第一缓冲块，套管的右端设置有第一缓冲块，第一缓冲块的右侧壁固定连接在所述第二支柱的左侧壁上，第二防护装置从左至右依次包括第二缓冲块、支撑杆、支撑弹簧、以及护栏本体，护栏本体的右表面设置有防护层。本发明通过在支柱上设置第一防护装置、第二防护装置，双重防护装置可提高防撞护栏对车辆的缓冲性，使得护栏本体可以始终防护在公路的两侧，对过往的车辆形成可靠的防护，避免车辆冲出路面，提高行车安全，本发明结构较为简单，成本较为低廉，适合推广使用。
