The invention belongs to the technical field of rail traffic safety protection, and particularly relates to a multi-level high-speed train anti-collision buffer. A multi-level high-speed train anti-collision buffer comprises an expansion cavity, an impact contact plate and a rear base plate, a buffer medium is arranged in the expansion cavity in advance, an oil pressing piston and a cavity partition plate are arranged in the expansion cavity, and the oil pressing piston comprises a pressing plate at the bottom, a pressing rod in the middle and a pressing head at the top. The pressing plate is located in the expansion cavity and not connected with the bottom of the expansion cavity, and the pressing head is located above the top of the expansion cavity. The left side and the right side of the oil pressing piston are each provided with a cavity division partition plate, the bottom ends of the cavity division partition plates are fixed to the bottom of the expansion cavity, the tops of the cavity division partition plates extend to the position above the top of the expansion cavity, and the interior of the expansion cavity is divided into a plurality of branch cavities through the cavity division partition plates. According to the buffering device, the traditional anti-collision energy-absorbing buffering mode that a rigid long rod extends to impact a compressible structural material is changed, and the energy-absorbing buffering effect is better.
本发明属于轨道交通安全防护技术领域,具体涉及一种多层级高速列车防撞缓冲器。一种多层级高速列车防撞缓冲器,包括膨胀腔体、冲击接触板和后垫板,膨胀腔体内预置有缓冲介质,膨胀腔体内部设置有压油活塞和分腔隔板,压油活塞包括底部的压板、中部的压杆和顶部的压头,压板位于膨胀腔体内部且不与膨胀腔体底部连接,压头位于膨胀腔体的顶部以上;在压油活塞的左右两侧各设置有一个分腔隔板,分腔隔板的底端固定在膨胀腔体的底部,而顶部延伸至膨胀腔体的顶部以上,分腔隔板将膨胀腔体内部分隔为多个分腔。该种缓冲装置改变了刚性长杆延伸撞击可压缩结构材料的防撞吸能缓冲的传统方式,吸能缓冲效果更好。
