Problems solved by technology

[0002] Ordinary railway turnouts have harmful spaces, and the wheels may lose their guidance and stray into different lines and cause derailment accidents. Therefore, it is possible to develop a ride-on railway turnout, that is, the wing rail and the core rail are designed as movable structures. , and raise the movable wing rail and the movable core rail, so that the wheels can cross the basic rail of the frog. How to realize the working stability of this structure and increase the maximum speed of the side line of the turnout is a problem that needs to be solved at present.

Embodiment Construction

[0019] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". The following descriptions in the specification are preferred implementation modes for implementing the present invention, but the descriptions are for the purpose of illustrating the general principles of the present invention, and are not intended to limit the scope of the present invention. The scope of protection of the present invention should be defined by the appended claims.

Abstract

The invention discloses a runover frog which comprises a frog stock rail, a movable wing rail, a movable point rail, a frog switch machine main unit, a movable wing rail switch machine auxiliary unit and a movable point rail switch machine auxiliary unit. The movable wing rail and the movable point rail are respectively positioned on two sides of the frog stock rail; on one side where the movable wing rail and the movable point rail are in abutted connection, railhead lower jaws of the movable wing rail and the movable point rail are identical with the top face of the frog stock rail in height, and a shape formed by the railhead lower jaws is coincident with that of an apex angle of the frog stock rail; one ends at which the movable wing rail and the movable point rail are in abutted connection are connected through a first screw of the frog switch machine main unit. Straight rails of the runover frog and the railway turnout eliminate harmful space of common turnouts, and side rails also eliminate harmful space, so that a train is stable in running; the runover frog is made of P75-type steel rails, so that frequent replacement of the movable point rail and the movable wing rail can be reduced, and high economic benefit can be brought about within a full service life period of the frog.

Description

technical field [0001] The invention relates to the technical field of railway turnouts, in particular to a ride-on frog and a railway turnout with the frog. Background technique [0002] Ordinary railway turnouts have harmful spaces, and the wheels may lose their guidance and stray into different lines and cause derailment accidents. Therefore, a ride-on railway turnout can be developed, that is, the wing rail and the core rail are designed as movable structures. , and raise the movable wing rail and the movable core rail, so that the wheels can cross the frog basic rail, how to realize the working stability of the structure and increase the maximum speed of the turnout side line is a problem that needs to be solved at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ride-on frog that eliminates harmful spaces, operates smoothly, and has economic benefits. [0004] In order to solve the above-mentione...
