The invention discloses a railway retarder ballast blocking prevention device and a method thereof. The railway retarder ballast blocking prevention device is characterized in that a retarder is fixedly connected with an upper connecting sleeve and a lower connecting sleeve, the upper connecting sleeve and the lower connecting sleeve are movably sleeved in an inner cavity of a top spigot sleeve, a spring is installed in an inner cavity of a base, and the upper connecting sleeve and the lower connecting sleeve slide up and down in the inner cavity of the top spigot sleeve and the inner cavity of the base. The bottom surface of the retarder is a distance away from the top surface of the spring, the bottom surface of the base is a distance away from rock ballast, the base is installed in a pre-digging hole of the track rock ballast, and when a traveling crane brakes and the retarder descends to the spring, the spring has rebound force to support the retarder for buffering, it is guaranteed that the retarder does not make direct contact with the track rock ballast surface, and the retarder is prevented from being jacked by the rock ballast to be damaged. The device is simple and reasonable in structure, easy to manufacture, convenient to install and use, large in safety coefficient, safe and reliable.

    本发明公开了一种铁路减速顶防碴堵塞装置及其方法,特征是减速顶与上下连接套固接,上下连接套活动套在顶止口套内腔,弹簧安装在底座内腔,上下连接套在顶止口套内腔和底座内腔上下滑行。减速顶底面离弹簧顶面有距离,底座底面离石渣有距离,底座安装在轨道石渣的预挖坑里,当行车刹车时,减速顶下行到弹簧时弹簧有反弹力托顶减速顶缓冲,保障减速顶不直接与轨道石渣面接触,避免减速顶被石渣顶压至损环。结构简单合理,制造容易,安装使用方便,保险系数大,安全可靠。
