By utilizing the mutual cooperation of the first stopper 3 and the second stopper 4, accurate and rapid positioning of the two guide rails is achieved, has a simple structure, is stable and reliable, and can realize automated docking control.

[0035] In the electric track crossing device of this embodiment, when it is in the undocking state, the electric push rod 1 is in the retracted state, the connecting rod assembly 2 drives the first stopper 3 to be set vertically, and the second stopper 4 is separated from the first stopper 3.
