Expressway safety multi-stage buffer device
The invention relates to a safety multi-stage buffering device for an expressway, and effectively solves the problem that multi-stage buffering cannot be formed when the vehicle speed is too high or serial collision occurs. According to the technical scheme, the device comprises a shell; a vertical plate is arranged in the shell, a first rectangular block and a rectangular plate are arranged on the vertical plate, the rectangular plate can rotate front and back, a torsional spring is arranged between the rectangular plate and the vertical plate and enables a rectangular rod to be perpendicular to the rectangular plate, and a transverse rod is arranged at the rear end of the vertical plate; a first through groove is formed in the rear end of the shell, a U-shaped block is arranged on the first through groove, a U-shaped plate is arranged in the shell, a second rectangular block is arranged in front of the U-shaped plate, and a long rod is arranged on the second rectangular block; the rectangular plates can rotate backwards and reset, and the multiple rectangular plates can rotate forwards in sequence and reset. The problem that multi-stage buffering cannot be formed when the vehicle speed is too high or serial collision occurs is solved, and the vehicle is decelerated through two times of multi-stage buffering, so the vehicle damage degree and the personnel injury degree are reduced.
本发明涉及一种高速公路安全多级缓冲装置，有效解决因车速过快或发生连环撞击时不能形成多级缓冲的问题；其解决的技术方案是包括壳体，壳体内有竖板，竖板上有第一矩形块和矩形板，矩形板能前后转动，矩形板与竖板之间有扭簧，扭簧能使矩形杆与矩形板保持垂直，竖板后端有横杆；壳体后端有第一通槽，第一通槽上有U形块，壳体内有U形板，U形板前方有第二矩形块，第二矩形块上有长杆；矩形板能向后转动并复位，多个矩形板能依次向前转动并复位；本发明解决了因车速过快或发生连环撞击时不能形成多级缓冲的问题，通过两次多级缓冲对车辆进行减速减轻车辆损伤和人员受伤程度。
