Road traffic anti-collision protection device
The invention relates to a road traffic anti-collision protection device which comprises a base, a stand column is fixedly connected to the upper end face of the base, a through hole is formed in the stand column, a cross beam is slidably connected into the through hole, horizontal transverse plates which are horizontally placed front and back are fixed to the two ends of the cross beam respectively, sinking grooves are formed in the left side and the right side of the base respectively, and a rectangular block is arranged in each sinking groove. The rectangular blocks can slide up and down, the upper end face of each rectangular block is fixedly connected with a plurality of blocking rods, after the rectangular blocks move upwards, the blocking rods can stretch out of the sinking grooves, after the transverse plate on one side moves towards the stand column under external force, the rectangular blocks on the non-stress side move upwards along the sinking grooves, and after the transverse plates make contact with the stand column and continue to move towards the stand column, the rectangular block on the stress side pops up; and after a vehicle collides with the device, the springs and the blocking rods on the two sides sequentially achieve different buffering and blocking effects at different times, triple buffering of the device on the collided vehicle is achieved, the vehicle speed is reduced in a fastest and effective mode, and the safety coefficient of the protective fence is greatly increased.
本发明涉及一种道路交通防撞飞防护装置，包括底座，底座上端面固定连接有立柱，立柱上开有通孔，通孔内滑动连接有横梁，横梁两端分别固定有一个水平前后放置横板，底座左右两侧分别开有一个沉槽，每个沉槽内有一个矩形块，矩形块能上下滑动，每个矩形块的上端面均固定连接有多个阻挡杆，矩形块向上移动后，阻挡杆能探出沉槽，当一侧的横板受外力向立柱方向移动后，未受力侧的矩形块沿沉槽向上移动，当横板接触立柱后继续向立柱方向移动后，受力侧的矩形块向上弹出；本发明通过车辆撞击装置后，弹簧和两侧的阻挡杆不同时间依次起到不同的缓冲阻挡效果，实现装置对撞击车辆的三重缓冲，用最快速有效的方式降低车速，大大提高了防护栏的安全系数。
