The invention relates to the technical field of collision energy absorption of rail transit, in particular to a threaded energy-absorbing anti-climbing device for a rail vehicle, a folding shell is arranged between an anti-climbing plate and a base, a plurality of groups of connecting pipes are arranged on the outer side of an auxiliary energy-absorbing rod in a circumferential array mode, folding pipes are arranged in the middles of the connecting pipes, and the connecting pipes distributed in the circumferential array mode are communicated through connecting ring pipes. The energy-absorbing anti-creeping device has the advantages that an existing energy-absorbing anti-creeping device is improved, the connecting pipe and the folding pipe are matched to wrap the foaming material, after installation is completed, the foaming material is used for filling, the whole body is made to collide and extend, the folding shell is made to extend, and therefore the energy-absorbing anti-creeping device is formed. Therefore, the cutting ring used for energy absorption and the external threads abut against the cutting knife, acceleration after collision caused by a buffering gap is avoided, buffering and energy absorption are conducted in time, and the overall buffering and energy absorption performance is improved.
本发明涉及轨道交通碰撞吸能技术领域,具体为一种轨道车辆螺纹式吸能防爬装置,防爬板和底座之间设置有折叠外壳,副吸能杆的外侧圆周阵列设置有多组连管,连管的中间设置有折叠管,圆周阵列分布的连管之间通过连接环管连通,连管的端部设置有接口,接口连接注入发泡材料的料泵,有益效果为:通过对现有吸能防爬装置进行改进,利用连管和折叠管的配合,从而包裹发泡材料,当安装完成后,利用发泡材料的填充,使得整体碰撞延伸,折叠外壳延伸,从而使得用以吸能的切削环和外螺纹抵在切削刀上,避免出现缓冲间隙,造成碰撞后的加速,及时的进行缓冲、吸能,从而提高了整体的缓冲吸能性能。
