摘　　要：我国铁路有四条长大重载运煤专线,2022年铁路煤炭总运量已达到27.9亿t,铁路货运总量49.84亿t,煤炭约占铁路货运总量的56%。运煤专线的列车有一个显著的特点,“满载而来、空载而归”,运煤专列货车在运输过程中只有全空和全重两种空重车状态。同时我国铁路货车空重车调整装置与世界先进水平相比还存在一定差距,列车在运用中,空重车调整装置存在作用性能及橡胶件密封可靠性较差、检修周期短等问题。基于这种现状,研究一种适用于我国铁路运煤专线的新型两级空重车调整装置,通过原理创新和结构创新,显著提升空重车调整装置作用性能和可靠性。Chinese railways contains four heavy-duty coal lines,realizing a total railway traffic of coal up to 2.79 billion tons in 2022 and a total railway freight traffic of 4.984 billion tons of which the coal transportation representing about 56%.The coal trains have an obvious characteristic that is“come fully loaded and return empty”,the coal cars have only two states during transportation:completely empty cars and fully loaded cars.Meanwhile,there is a certain gap between the empty/load adjusting equipment for Chinese railway wagons and the world advanced level.During operation of train,the empty/load adjusting equipment presents problems such as lower reliability of operational performance and airtightness of rubber parts and shorter maintenance cycle.Based on this actuality,the article studies a new type of two-stage empty/load adjusting equipment applicable to Chinese railway coal lines which can obviously improve the operational performance and the reliability of the empty/load adjusting equipment through innovation of principle and structure.
