具体的，参照图2a至图2c所示，图2a为本发明提供的一种货运列车底架连接多个第二底架模块的结构示意图。图2b为本发明提供的一种货运列车底架连接单个第二底架模块的结构示意图。图2c为本发明提供的一种货运列车底架未连接第二底架模块的结构示意图。本实施例提供的货运列车底架1 为适应不同尺寸长度的货物或者集装箱，可以是多个第二底架模块120相互之间通过连接模块130连接后，再通过连接模块130与第一底架模块110进行连接。如此，实现货运列车底架1长度可调节，能够适应不同尺寸长度的货物。可选的，参照图2c所示，在货物尺寸较短时，本实施例提供的货运列车底架1可以仅由两个第一底架模块110通过连接模块130连接而成。如此，避免了在列车底架长度固定的情况下，对于尺寸较小的货物，列车底架空间富余，避免了空间浪费，提高了货运列车的空间利用率和货运列车的运输量。
可选的，本实施例中提供的货运列车底架，第二底架模块120与第一底架模块110通过至少两个连接模块130连接，第二底架模块120之间通过至少两个连接模块130连接。

进一步的，参照图3和图4所示，本实施例提供的货运列车底架。连接模块130还包括调整板135，调整板135的厚度可调，调整板135用于在胀紧器134用于插入异形孔1311内时与第二连接件132相抵接。
