The invention relates to the technical field of rail transit, and discloses an anti-derailment train coupler, which comprises a fixed seat, wherein the fixed seat is fixedly connected with a connecting rod, the connecting rod is connected with a connecting hook through the connecting seat, an unhooking pin is arranged on the connecting hook, and a wedge-shaped table is arranged on the upstream ofthe upper surface of the connecting rod. According to the anti-derailment train coupler, when a train is derailed, automatic unhooking is conducted, so that the influence of derailment carriages on rear carriages is avoided; the connecting rods of the on-track carriages are inserted into pressing grooves of the derailment carriages, and impact and extrusion force between the two carriages are changed into the derailment carriages to press the on-track carriages, so that the probability of continuous derailment of the rear on-track carriages is reduced so as to avoid the further expansion of accidents; and energy absorption is conducted through fracture of an energy absorption substance and a shear pin in a pressing groove to reduce impact damage, the connecting rod and the connecting hookare actively made to fall off and are directly fixed through the inserting plate, so that expansion of the accident caused by random falling of the inserting plate can be avoided.

    本发明涉及轨道交通技术领域,且公开了一种防脱轨的列车车钩,包括固定座,所述固定座固定连接有连接杆,所述连接杆通过连接座连接有连接钩,所述连接钩上设有脱钩销钉,所述连接杆的上表面上游楔形的楔形台。该防脱轨的列车车钩,列车脱轨时,自动脱钩,避免脱轨车厢对后面车厢的影响,同时通过在轨车厢的连接杆插入脱轨车厢的按压槽中,将两个车厢之间的撞击和挤压力变为脱轨车厢按压在轨车厢,继而降低后方在轨车厢继续脱轨的几率,避免事故的进一步扩大,其次,通过按压槽中的吸能物质和剪切销钉的断裂进行吸能,减少撞击伤害,并且主动使连接杆和连接钩掉落,并直接通过插板固定,可避免插板随机掉落引起事故的扩大。
