The invention relates to a rail chassis assembly and a rail-mounted crane. The rail chassis assembly is used for the rail-mounted crane capable of being converted into multiple tonnages and comprises a plurality of roadbed box sets and a plurality of annular rails, each roadbed box set comprises a plurality of roadbed boxes capable of being arranged in a sector ring shape or a circular ring shape in the circumferential direction, and the radiuses of sector rings or circular rings corresponding to the roadbed box sets are different; each annular rail is in a closed or non-closed circular ring shape; under the maximum-tonnage circular rail operation working condition, the multiple roadbed box sets are arranged to form a first bottom foundation of the rail-mounted crane, the multiple roadbed box sets are concentrically arranged in the radial direction, and the multiple circular rails are concentrically arranged on the upper surface of the first bottom foundation; and under other circular rail operation working conditions of at least partial tonnages, at least partial roadbed box sets of the multiple roadbed box sets are arranged as a second bottom foundation of the rail-mounted crane, and partial circular rails of the multiple circular rails are concentrically arranged on the upper surface of the second bottom foundation.

    本公开涉及一种轨道底盘组件及轨道式起重机。轨道底盘组件用于可转换成多个吨位的轨道式起重机,包括:多个路基箱组,每个路基箱组包括能够被沿周向排布成扇环形或圆环形的多个路基箱,各个路基箱组对应的扇环形或圆环形的半径不同;和多个环形轨道,每个环形轨道呈封闭的或非封闭的圆环形;其中,在最大吨位的环轨运行工况下,多个路基箱组被布置成轨道式起重机的第一底部基础,且多个路基箱组同心且沿径向排布,多个环形轨道同心地设置在第一底部基础的上表面;在其他至少部分吨位的环轨运行工况下,多个路基箱组的至少部分路基箱组被布置成轨道式起重机的第二底部基础,且多个环形轨道中的一部分环形轨道同心地设置在第二底部基础的上表面。
