A multi-stage multi-dimensional combined type anti-creeping energy absorption device comprises an energy absorption device mounting plate, an anti-creeping tooth mounting plate and a thin-walled pipe between the energy absorption device mounting plate and the anti-creeping tooth mounting plate, and a plurality of main guide rods are further arranged between the energy absorption device mounting plate and the anti-creeping tooth mounting plate; the inner diameter of the cutting sleeve is smaller than that of the guide pipe, and the outer diameter of the cutting sleeve is consistent with that of the guide pipe; an upper step structure is arranged on the radial outer side face of the first open end of the cutting sleeve, and a guide part extending into the guide pipe in the axial direction of the first open end is arranged on the radial inner side of the first open end. A cutting tool for cutting the upper step structure is arranged on the end face of the second open end of the guide pipe, and a guide slope for guiding the guide part to move into the guide pipe is arranged on the radial inner side face of the second open end; a high-pressure air bag capable of being axially compressed is mounted in the guide pipe; and a multi-stage crushing material layer capable of crushing in the axial direction is arranged in the cutting sleeve. The multi-layer and multi-dimensional longitudinal energy absorption and anti-creeping and anti-deviation effects can be achieved.

    一种多级多维度组合式防爬吸能装置,包括吸能装置安装板、防爬齿安装板和两者之间的薄壁管,吸能装置安装板和防爬齿安装板之间还设有多根主导向杆;还包括切削套筒和导向管,切削套筒内径小于导向管内径,切削套筒外径与导向管外径一致;切削套筒的第一敞口端的径向外侧面设置有上台阶结构,第一敞口端的径向内侧设有沿其轴向延伸至导向管内的导向部;导向管的第二敞口端端面设置有用于切削上台阶结构的切削刀具,第二敞口端径向的内侧面设置有引导导向部向导向管内移动的引导斜面;导向管内安装有能被轴向压缩的高压气囊;切削套筒内设有能够沿轴向溃缩的多级压溃材料层。本发明能够实现多层级多维度的纵向吸能和防爬防偏作用。
