摘要
开行重载列车区段进行自动闭塞改造时,会产生危及行车安全的问题。本文首先阐述了对于开行重载列车自动闭塞改造过程中尤为突出的两个问题:"起得来"、"停得住"。"起得来"就是列车在长大上坡道区间通过信号机前停车后,在粘着良好、牵引力发挥正常条件下,能够在该区段完成上坡道起动作业。"停得住"就是货车在连续长大下坡道上运行能够满足《技规》的相关规定。其次给出了自动闭塞改造过程上述2个问题的验算原则,并结合案例进行了计算。最后对于不能满足自动闭塞改造条件的情况,提出了"突破限制速度"和"3机牵引"的解决方案。
Many safety problems will be appread during the renovation of automatic block section with heavy-duty train. This paper expounds two especial problems of the renovation process, ＂start＂ and ＂stop＂ . ＂Start＂ means the train can get start when it was stoped before the interval signal in the up gradi- ent. ＂Stop＂ means the train can satisfy the relevant provisions of the technical rules when running in the continuous down gradient. Secondly, two calculation principles were given about the problems of the auto- matic block transformation process, and a case was given too. Finally, two methods of ＂break through the limit velocity＂ and ＂3 machine traction＂ were given during the situation which can not satisfy the automatic block transformation conditions.
