The invention discloses a crushing type omni-directional anti-creeper for a railway vehicle. The omni-directional anti-creeper is provided with an anti-creeper toothed plate, and an anti-creeper tooth array which is regularly arranged in a chessboard mode is arranged on the anti-creeper toothed plate; each anti-creeper tooth is provided with a top guide section and a bottom meshing section, the top guide section is of a conical variable cross-section structure, and the bottom meshing section is of a columnar uniform cross-section structure; the left side, the right side, the upper side and the lower side of each anti-creeper tooth are provided with concave parts used for containing the anti-creeper teeth of the collision anti-creeper; an energy absorption pipe of the anti-creeper is changed into a two-dimensional cross section pipe wall with a porous cross section from a traditional round pipe with a simple section solid pipe wall; and/or, the anti-creeper assembly replaces traditional welding with completely detachable threaded connection. According to the omni-directional anti-creeper, automatic centering can be always achieved, the energy absorption effect is greatly improved, and compactness, usability, replaceability and maintainability of the omni-directional anti-creeper are all enhanced.

    一种全向防爬器,该防爬器具有防爬齿板,该防爬齿板上设有棋盘式规则排布的防爬齿阵列;每个防爬齿设有顶部引导段和底部啮合段,顶部引导段具有锥形式变截面结构,而底部啮合段具有柱状等截面结构;在每个防爬齿的左右两侧和上下两侧,设有用于容纳相撞防爬器的防爬齿的凹部。防爬器的吸能管由传统的简单截面实心管壁的圆管改为截面具有多孔特征的二维横截面管壁;和/或,防爬器装配体以完全可拆卸的螺纹连接替换传统的焊接。根据本发明的全向防爬器,总能够实现自动对中,吸能效果得以大幅升级,全向防爬器的紧凑性、易用性、可替换性、可维修性均得以增强。
