The invention relates to a train humping marshalling duplex retarder. The problem that no compensation function exists when a retarder breaks down and is disabled is effectively solved. According to the technical scheme, the device comprises a grooved rail with a U-shaped section, the grooved rail is fixed to a train rail through bolts, a front retarder and a rear retarder are installed in the grooved rail and arranged in a spaced mode, the front retarder is located in the coming direction of a train, the rear retarder is located in the going direction of the train, and the front retarder is in an extending state. The rear retarder is in a non-stretching locking state, and when the front retarder is disabled, the rear retarder is unlocked and stretches out to replace the front retarder to work; by means of the method, compensation can be conducted on the disability of the retarder when the retarder has a false roof fault and a dead roof fault, and safe deceleration during train humping marshalling is guaranteed.
本发明涉及一种列车溜放编组双联减速顶,有效的解决了减速顶发生故障失能时无代偿功能的问题;解决的技术方案包括截面为U型的槽轨,槽轨经螺栓固定在列车轨道上,槽轨内装有一个前置减速顶和一个后置减速顶,前置减速顶和后置减速顶间隔设置,前置减速顶位于列车来向,后置减速顶位于列车去向,前置减速顶处于伸出状态,后置减速顶处于未伸出锁定状态,当前置减速顶出现失能时,后置减速顶解锁伸出代替前置减速顶工作;本发明能在减速顶发生“假顶”故障和“死顶”故障时对减速顶的失能进行代偿,确保列车溜放编组时的安全减速。
