The rail vehicle according to claim 2, further comprising a limiting portion, wherein the limiting portion is vertically arranged on the movable component and synchronously acts with the movable component, when the lifting type rail-changing device acts in place, one end of the linkage limiting portion is clamped into the limiting portion through the elastic component, and the movable component is constrained through the cooperation of the linkage limiting portion and the limiting portion.

4. The rail vehicle according to claim 3, wherein the limiting portion includes a limiting groove, and when the lifting type rail-changing device is in place, one end of the linkage limiting portion is clamped into the corresponding limiting groove under the elastic force of the elastic component, and the movable component is restrained;

or, spacing portion includes two spacing grooves, two spacing grooves set up respectively in the not co-altitude department of movable part, when over-and-under type becomes rail device and moves, the one end of the about portion of linkage is in for movable part move between two spacing grooves, when over-and-under type becomes rail device and moves in place, the one end of the about portion of linkage is gone into corresponding spacing groove under elastic component's elastic force effect to realize the restraint to movable part.

5. The rail vehicle as claimed in claim 4, wherein an arc guide part is provided at the notch of the limit groove, and/or an arc guide part is provided at one end of the linkage constraint part.

6. The rail vehicle as claimed in claim 3, wherein the linkage constraint part and the frame form a rotation pair or a moving pair, and the linkage constraint part is a linkage rod, a linkage plate, a combination of a plurality of linkage rods, a combination of a plurality of linkage plates, or a combination of a linkage rod and a linkage plate; the elastic component is one or a combination of more of an extension spring, a compression spring or a torsion spring.

7. The rail vehicle as claimed in claim 3, wherein the linkage constraint portion is provided at an end thereof with a roller or a ball head for being caught in and withdrawn from a corresponding limit groove.

8. The railway vehicle according to claim 3, wherein the stopper portion is integrally formed with the movable member, or the stopper portion is fixed to the movable member by welding, bonding, bolting, or riveting.

9. The rail vehicle according to claim 3, characterized in that the limiting portion comprises a groove of W-shaped configuration or a limiting plate of W-shaped configuration.

10. The rail vehicle as claimed in claim 4, wherein the lifting type rail transfer device comprises a driving motor and a reverse synchronization mechanism, the reverse synchronization mechanism comprises an upper swing arm, a lower swing arm and two vertically arranged connecting rods, rail transfer wheels are respectively arranged at the tops of the connecting rods, two ends of the upper swing arm and two ends of the lower swing arm are respectively hinged to the two connecting rods, and four hinged parts are respectively located at four vertexes of a parallelogram; the middle parts of the upper swing arm and the lower swing arm respectively form a revolute pair with the supporting seat, the supporting seat is fixed on the frame, and the driving motor is connected with the middle parts of the upper swing arm or the lower swing arm and used for driving the track-changing wheels on one side to ascend and the track-changing wheels on the other side to descend synchronously; the movable part is a connecting rod, an upper swing arm or a lower swing arm.
