摘要

为解决单机紧急停车过程中由于大量撒砂造成自闭区段轨道电路分路不良，机车占用闭塞分区无显示，易导致追尾的严重问题，开发了单机紧急制动自动截止撒砂装置，并对该装置进行了全面的静态、动态试验以对设计功能进行有效的验证，最后根据试验情况找出了需要完善的项点。

Abstract

To solve the serious problem of automatic block district track circuit bad shunting caused by massive sanding in single locomotive emergency stop and locomotive occupying block district with no display, which caused frequently rear-end collision accident, automotive cut-off sanding device in single locomotive emergency braking was developed. Design function of the device was verified and advanced by overall static and dynamic test.
