Core-inlaid type high manganese steel frog structure

Abstract

The invention provides a core-inlaid type high manganese steel frog structure, comprising a high manganese steel frog structure body and an inlaid core; the high manganese steel frog structure is integrally casted and shaped, and comprises a wing rail connecting section, a fork core section and a fork-rail connecting section; the wing rail connecting section and the fork-rail connecting section are respectively arranged at front and back ends of the fork core section; the front part of the fork core section is provided with an installing groove for cooperatively mounting the inlaid core; a frog body is detachably connected with the inlaid core. The inlaid core comprises an upper connecting section and a lower connecting section; an arc transition is arranged between a point of the upper connecting section and the upper end face of the lower connecting section, the back end face of the upper connecting section is cooperatively connected with the front end face of the fork core section, the upper end face of the inlaid core and the upper end face of the fork core section are located at the same one plane. In the invention, the high manganese steel frog body is detachably connected with the inlaid core, and can conveniently replace the fragile part, save cost while meet the using requirement; the inlaid core can apply materials and production techniques which are different from the fork body, thus the using performance of the inlaid core is improved. The core-inlaid type high manganese steel frog structure is reasonable in design, and safe and reliable in use.

Description

Technical field [0001] The invention relates to the technical field of railway turnouts, in particular to a core-inlaid high-manganese steel frog structure. Background technique [0002] Frogs are a key component of railway turnout systems. High-manganese steel frogs are widely used worldwide due to their unique characteristics. With the continuous increase of railway operating mileage in my country, the demand for high manganese steel frogs continues to increase. At the same time, the increase in railway carrying capacity and speed also accelerates the wear of high manganese steel frogs and reduces the service life of the frogs. Studies have found that the high manganese steel frog is not damaged as a whole, but there is a local harmful space. Within the harmful space, the surface layer of the high manganese steel frog is likely to peel off, affecting normal use. The high manganese steel frog itself It is not easy to repair, so it can only be scrapped directly, which causes gre...

The study found that the high manganese steel frog is not damaged as a whole, but there is a local harmful space. In the harmful space, the surface layer of the high manganese steel frog is prone to peeling off, affecting normal use, and the high manganese steel frog itself It is not easy to repair, so it can only be scrapped directly, which causes great waste
