The invention discloses an extendable gauge-adjustable low-speed rail trolley frame structure. The structure comprises closed boxes and a control system which are symmetrical to each other, the two sides of the two closed boxes are fixedly connected with a first frame and a second frame respectively, a distance adjusting mechanism is arranged between the first frame and the second frame, stabilizing mechanisms are arranged in the first frame and the second frame, the distance adjusting mechanism comprises a hollow pipe and a solid pipe, and the inner surface of the hollow pipe is in sliding connection with the outer surface of the solid pipe. The invention relates to the technical field of trolley frames. According to the extendable gauge-adjustable low-speed rail trolley frame structure, the distance adjusting mechanism is arranged, spring columns and through grooves are used for achieving clamping connection, and the distance is adjusted in cooperation with mutual sliding of the hollow pipe and the solid pipe, so that the gauge of the bottoms of the frames is adjusted, rail replacement of a trolley is facilitated, meanwhile, troubles caused by dismounting and replacing are avoided, and the operation of replacing the distance between vehicles is more convenient and faster.

    本发明公开了一种具有延伸性的可调轨距低速轨道小车车架结构,包括相互对称的密闭箱和控制系统,两个所述密闭箱的两侧分别固定连接有第一车架和第二车架,所述第一车架和第二车架之间设置有调距机构,所述第一车架和第二车架的内部设置有稳固机构,调距机构中包括空心管和实心管,且空心管的内表面与实心管的外表面滑动连接,本发明涉及小车车架技术领域。该具有延伸性的可调轨距低速轨道小车车架结构,通过设置有调距机构,利用弹簧柱与通槽实现卡接,配合空心管和实心管的相互滑动进行调距,从而实现了对车架底部的轨距进行调节,便于小车进行轨道的更换,同时避免了拆除更换造成的麻烦,使得更换车距的操作更加的便捷。
