Abstract

The present disclosure relates to a track travelling device, comprising a vehicle body, a connection device and two groups of wheels. The two groups of wheels are disposed on two sides of the vehicle body respectively and the wheels comprise rims matched with tracks. One end of the connection device is connected to a bottom of the vehicle body and the other end of the connection device is connected to the wheels. The connection device comprises an elastic member and the elastic member is configured to be deformed under the gravity of the vehicle body to adjust distances between the rims of the two groups of wheels. Under the gravity of the vehicle body, the track travelling device of the present disclosure can closely attach the rims of the wheels to side surfaces of the tracks, thereby preventing the vehicle body from swaying side to side. Meanwhile, the connection device comprises the elastic member for adaption to a change of a track gauge.
