The invention relates to the technical field of anti-creeper, and provides a self-centering friction type anti-creeper energy absorption device which comprises an energy absorption pipe, an anti-creeper part, a mounting part, a supporting part and at least one friction energy absorption unit arranged in the energy absorption pipe. According to the self-centering friction type anti-creeping energy absorption device, the friction energy absorption units which absorb energy in a relative friction mode are adopted, so that energy can be effectively absorbed when a train collides in a centering mode to dissipate collision energy, and when the train collides in an eccentric mode, the friction energy absorption units can effectively absorb the energy to dissipate the collision energy; in addition, eccentric extrusion force can be effectively absorbed and resisted through the friction energy absorption unit, so that the risk of overall failure of the anti-creeping energy absorption device under the eccentric collision condition is effectively reduced, and the reliability of the anti-creeping energy absorption device in actual application is further improved.

    本发明涉及防爬器技术领域,提供了一种自对中摩擦式防爬吸能装置,包括吸能管、防爬部、安装部、支撑部以及至少一个设置于吸能管内部的摩擦吸能单元。本发明提供的自对中摩擦式防爬吸能装置通过采用以相对摩擦的方式进行吸能的摩擦吸能单元,除了能够在列车发生对心碰撞时进行有效吸能以实现耗散碰撞能量外,当列车发生偏心碰撞时,还能够利用摩擦吸能单元有效吸收并抵御偏心挤压力,从而有效降低防爬吸能装置在偏心碰撞情况下整体失效的风险,进一步提高了防爬吸能装置在实际应用时的可靠性。
