The invention discloses a self-adjusting anti-climbing energy absorption device which comprises an upper cover plate, a lower cover plate, an energy absorption unit and self-adjusting sliding rods, the upper cover plate and the lower cover plate are oppositely arranged, and the energy absorption unit is arranged between the upper cover plate and the lower cover plate and fixedly connected with the inner surface of the upper cover plate and the inner surface of the lower cover plate; and self-adjusting sliding rods are further arranged on the peripheral face of the upper cover plate and the peripheral face of the lower cover plate, one end of each self-adjusting sliding rod is connected to the peripheral face of the upper cover plate and can horizontally slide on the peripheral face of the upper cover plate, and the other end of each self-adjusting sliding rod is connected to the peripheral face of the lower cover plate and can horizontally slide on the peripheral face of the lower cover plate. According to the self-adjusting anti-climbing energy absorption device, the self-adjusting sliding rods are arranged on the periphery of the energy absorption unit, when eccentric collision occurs, the energy absorption unit in non-contact area can still generate elasticoplastic deformation through the interaction between the self-adjusting sliding rods and the upper cover plate and the interaction between the self-adjusting sliding rods and the lower cover plate, and therefore it is guaranteed that the energy absorption device cannot lose the energy absorption effect.
本发明公开了一种自调整防爬吸能装置,包括上盖板、下盖板、吸能单元、自调整滑杆,所述上盖板与所述下盖板相对设置,所述吸能单元设在所述上盖板与下盖板之间,并与所述上盖板、下盖板的内表面固定连接;所述上盖板与下盖板的外周面还设有自调整滑杆,所述自调整滑杆的一端连接在所述上盖板的外周面、并可在所述上盖板的外周面上水平滑动,另一端连接在所述下盖板的外周面、并可在所述下盖板的外周面上水平滑动。本发明的自调整防爬吸能装置通过在吸能单元的四周设置自调整滑杆,在发生偏心碰撞时,能够通过自调整滑杆与上、下盖板之间的相互作用,使未接触区域的吸能单元仍然发生弹塑性变形,从而保证了吸能装置不会丧失吸能作用。
