Highway crash barrier
The invention relates to the technical field of highway safety facilities, and discloses a highway crash barrier. The highway crash barrier comprises landing vertical rods, and the number of the landing vertical rods is two. Sleeves are fixedly mounted on the corresponding sides of the two landing vertical rods, and the number of the sleeves is two. A transverse rod is movably connected between the interiors of the two sleeves in a sleeving mode, a vertical rod located between the sleeves is fixedly connected into the transverse rod in a sleeving mode, supporting rods are fixedly installed onthe two sides, located below the transverse rod, of the vertical rod, and a telescopic device is movably connected to the bottom of the vertical rod. According to the highway crash barrier, the sleeves, the transverse rod and the telescopic plate are arranged, and when the two landing vertical rods move back to back, the transverse rod can be pulled out of the two sleeves, meanwhile, the wave-shaped telescopic plate on the lower portion is stressed to stretch, and therefore the length of the crash barrier is changed, and road maintenance personnel can effectively prolong the crash barrier without increasing the number of the crash barrier.
本发明涉及公路安全设施技术领域，且公开了一种公路防撞护栏。该公路防撞护栏包括落地立杆，所述落地立杆的数量为两个，两个所述落地立杆相对应的一侧均固定安装有套筒，所述套筒的数量为两个，两个所述套筒的内部之间活动套接有横杆，所述横杆的内部固定套接有位于套筒之间的竖杆，竖杆位于横杆下方的两侧均固定安装有支撑杆，竖杆的底部活动连接有伸缩装置。该公路防撞护栏，通过设置套筒、横杆和伸缩板，当两个落地立杆相背运动的时候，将会使得横杆从两个套筒中抽出，同时下方的波形伸缩板受力伸张，从而改变了该防撞护栏的长度，使得公路维护人员不需要增加防撞护栏的数量，即可实现防撞护栏的有效延长。
