According to the anti-rotation device, the anti-creeping energy absorption device and the railway vehicle, the limiting groove used for containing the special-shaped nut is formed in the base of the anti-rotation device, at least one set of limiting walls are arranged in the limiting groove so as to limit at least one set of opposite sides of the special-shaped nut, the anti-rotation baffle is arranged above the limiting groove, and the anti-creeping energy absorption device is arranged above the anti-rotation baffle. The anti-rotation baffle is provided with an anti-rotation blocking table extending into the limiting groove to limit the other edges of the special-shaped nut, and all the edges of the special-shaped nut are limited and prevented from rotating through cooperation of the limiting baffle and the limiting groove so that torque can be applied. A first through hole corresponding to a threaded hole of the special-shaped nut is formed in the groove bottom of the limiting groove, and a second through hole corresponding to the threaded hole of the special-shaped nut is formed in the anti-rotation baffle in a penetrating mode so that a part to be installed can conveniently penetrate through the first through hole to be fixed to the special-shaped nut in a threaded mode. Therefore, application of torque is guaranteed, and the anti-rotation function is achieved. Limiting operation does not need to be provided in the torque applying process, replacement is convenient when damaged, only the special-shaped nut needs to be replaced, and cost is reduced.

    本申请实施例中提供了一种防转装置、防爬吸能装置以及轨道车辆,防转装置在底座上设置用于容置异形螺母的限位槽,限位槽内设有至少一组限位壁,以对异形螺母的至少一组对边进行限位,在限位槽的上方设置防转挡板,防转挡板设有延伸至限位槽内的防转挡台对异形螺母的其余边进行限位,通过限位挡板和限位槽的配合对异形螺母的各边进行限位防转以施加扭矩;限位槽的槽底设有与异形螺母的螺纹孔对应的第一通孔,防转挡板贯通设有与异形螺母的螺纹孔对应的第二通孔,以方便待安装部件穿过第一通孔与异形螺母进行螺纹固定。由此以保证扭矩的施加并实现防转功能;保证施加扭矩过程无需提供限位操作,在损坏时方便更换,仅需异形螺母更换即可,降低成本。
