The embodiment of the invention provides an energy-absorbing anti-creeping device and a railway vehicle. The energy-absorbing anti-creeping device comprises an energy-absorbing barrel and an anti-creeper, and the anti-creeper is located at one end, in the axial direction, of the energy-absorbing barrel; the connecting assembly is arranged at the end, away from the anti-creeper, of the energy absorption cylinder in a sleeving mode in the axial direction, the connecting assembly comprises a radial connecting part and an axial connecting part, the radial connecting part is used for being fixed to a vehicle body floor, a tool mounting hole is formed in the circumferential outer wall of the axial connecting part, and a tool mounting concave part corresponding to the tool mounting hole is arranged on the circumferential outer wall of the energy absorption cylinder; and the cutter is positioned in the cutter mounting hole and the cutter mounting concave part along the radial direction. An anti-creeper is fixed to a vehicle body floor through a radial connecting part, a cutter mounting hole is formed in the circumferential outer wall of an axial mounting part, and a cutter is arranged on the circumferential outer wall of an energy absorption cylinder; therefore, the mounting mode of the cutter and the energy-absorbing cylinder is changed, so that in the process of dismounting and mounting the device and the vehicle body floor, no obstruction is caused, and the cutter and the energy-absorbing cylinder do not need to be dismounted and mounted.
本申请实施例中提供了一种吸能防爬装置及轨道车辆,包括:吸能筒体和防爬器,防爬器位于吸能筒体沿轴向的一端;连接组件,沿轴向套装于吸能筒体背离防爬器的一端,连接组件包括径向连接部和轴向连接部,径向连接部用于与车体地板固定,轴向安装部的周向外壁设有刀具安装孔,吸能筒体的周向外壁设有与刀具安装孔对应的刀具安装凹部;刀具沿径向位于刀具安装孔和刀具安装凹部内。其防爬器通过径向连接部与车体地板进行固定,轴向安装部的周向外壁设置刀具安装孔,将刀具设置在吸能筒体的周向外壁上;由此以改变刀具与吸能筒体的安装方式,使装置在与车体地板拆装的过程中,不造成阻碍,无需对刀具和吸能筒体进行拆装。
