Abstract

A ground rail transfer device includes: a support rail provided on the ground and used for unloading a vertical load of a bogie in a rail vehicle; a guide rail provided on the ground and used for driving the bogie to perform a rail transfer operation; and a transition plate provided on the ground and located between a first rail and a second rail which are different in a gauge; wherein a difference between the top surface height of the transition plate and the top surface height of the first rail is equal to a distance between a wheel rim vertex circle and a wheel tread of the rail vehicle.

Claims17

Dependent claims

A ground railway transfer device for driving a railway vehicle to switch between a first railway and a second railway, the first railway having a gauge called as a first gauge, the second railway having a gauge called as a second gauge, the first gauge being different from the second gauge;

the first railway and the second railway extending in a longitudinal direction, wherein the ground railway transfer device comprises:
a support rail arranged on the ground and configured for unloading a vertical load of a bogie in the railway vehicle;
a guide rail arranged on the ground and configured for driving the bogie to perform a railway transfer operation, such that the bogie switches between the first gauge and the second gauge;
a transition plate arranged on the ground and located in the longitudinal direction between the first railway and the second railway, a difference in a height direction between a top surface of the transition plate and a top surface of the first railway being equal to a distance between a wheel rim tip circle and a wheel tread of the railway vehicle,
wherein
the guide rail comprises:
two guide bodies with a same structure, the two guide bodies being symmetrically distributed on both sides of the transition plate;
each of the guide bodies is provided with a guide structure, the guide structure is a guide groove for accommodating a railway transfer guide member arranged on the bogie, a side wall of the guide groove being in contact with the railway transfer guide member to provide the railway transfer driving force to the railway transfer guide member;
and
wherein a center line of the guide groove is at a set angle to the longitudinal direction;
a difference in the transverse distances between two ends of the center line of the guide groove and an extension line of a center line of the first rail is equal to one half of a difference between the first gauge and the second gauge.
