Abstract
The middle-low speed magnetic levitation track structure with the variable track gauge conveniently realizes the track gauge adjustment and greatly reduces the construction cost of a test field. The sleeper comprises a sleeper fixedly arranged on a support structure under a rail through a fastener, wherein the center of the sleeper is disconnected to form a left sleeper and a right sleeper which are symmetrically arranged relative to the central line of a line, and longitudinal adjusting through holes and vertical adjusting through holes corresponding to different gauges are respectively formed on a waist vertical plate and a bottom flange of the left sleeper and the right sleeper at intervals. The left sleeper and the right side sleeper are connected into a whole by the bolt component passing through the two side mounting holes and the longitudinal adjusting through holes corresponding to the track gauges. The main body of the fastener passes through the vertical adjusting through holes corresponding to the track gauge to fixedly mount the left sleeper and the right sleeper on the lower rail supporting structure below the left sleeper and the right sleeper.
