The invention discloses a rail train and a rail gauge changing device thereof, and relates to the technical field of rail traffic, and the rail gauge changing device comprises a rail changing line, a rail changing bogie, a magnetic circuit guide rail, a magnetic circuit coil assembly, a rotary hydraulic cylinder, a distance detection module and an oil supply module. The orbital transfer bogie can move on an orbital transfer line, the magnetic circuit coil assembly and the magnetic circuit guide rail repel each other through a magnetic field so as to unload loads acting on wheels, the rotary hydraulic cylinder comprises a cylinder body and a piston rod, and the distance detection module is used for detecting the distance between the wheels and the center of an axle. And the oil supply module is used for supplying oil to the rotary hydraulic cylinder when the distance detected by the corresponding distance detection module is inconsistent with the set orbital transfer distance, so that the piston rod extends or retracts relative to the cylinder body, and the distance between the wheel and the center of the axle is adjusted. According to the gauge changing device, the overall structure of the bogie can not be damaged, rapid track changing can be achieved, the track changing time is greatly shortened, the transnational train operation efficiency is improved, and the manpower and material resource cost is reduced.
本申请公开了一种轨道列车及其变换轨距装置,涉及轨道交通技术领域,变换轨距装置包括变轨线路、变轨转向架、磁路导轨、磁路线圈组件、旋转液压缸、距离检测模块和供油模块。变轨转向架可在变轨线路上移动,磁路线圈组件与磁路导轨通过磁场排斥,以对作用于车轮上的载荷进行卸载,旋转液压缸包括缸体和活塞杆,距离检测模块用于检测车轮与车轴中心的距离,供油模块用于在对应的距离检测模块检测到的距离与设定的变轨距离不一致时向旋转液压缸供油,使得活塞杆相对缸体伸出或缩回,实现车轮与车轴中心的距离调节。上述变换轨距装置能够不破坏转向架整体结构并能够快速变轨,大幅减少了变轨时间,加快了跨国列车运行效率,降低了人力和物力成本。
