Description

Railway frog

Technical Field

The utility model relates to the technical field of track turnouts, in particular to a railway frog.

Background

Frog is a key component of railway turnout and plays a role in guiding the crossing direction change of a train on a line. The alloy steel combined frog is mainly formed by connecting a wing rail, an alloy steel frog core and a fork heel rail through high-strength bolts and nuts, wherein the wing rail has the function of ensuring that locomotive wheels safely pass through important parts of the frog. At present, an alloy steel combined frog wing rail for a common speed railway and urban rail transit is generally manufactured by adopting a 60kg/m steel rail, and when the type turnout is maintained and replaced, the maintenance workload of alloy steel parts is large because of the large space between the rail web and the rail head edge of the 60kg/m steel rail, so that the separation iron between the wing rail and the alloy steel and the dismounting of the wing rail piece are difficult. The structural form of the alloy steel fork core combined frog used on the current line is that a U75V on-line quenching steel rail is used for wing rails and fork following rails, and a forged bainitic steel is used for the fork core. When the wheel passes through the frog, the strength and toughness of the forged bainitic steel are higher than those of the steel rail, and the damage to the wing rail caused by the impact and crushing of the wheel when the train goes into the fork in the forward direction is more than that of the fork center, so that the service lives of the wing rail and the fork center are inconsistent in use, and the passing total amount of part of alloy steel frog is reduced in advance due to the damage of the wing rail.

The prior art has the following problems:

Through searching, chinese patent publication number: CN217203392U provides a railway switch frog structure, by setting up straight stock rail and fork follow rail on the backing plate and constitute, including the wing rail of discrete setting to and set up the fork center between two wing rails, and run through fixedly through bolt and nut, the lateral wall of fork center is with adjacent parts complex terminal surface structure, set up the spacer iron between wing rail and the fork center, be equipped with the insert between spacer iron and the wing rail, two sides of insert have can with spacer iron or wing rail matched with terminal surface, the width of the railhead of the working limit of wing rail is less than the width of its non-working limit, and this patent is through the interval of changing the railhead working face of wing rail, increases the distance between wing rail and the fork center, can effectively solve the part dismouting that present alloy steel combination frog exists and change the problem of difficulty, in order to reduce work maintenance work load.

However, the problem that the above patent still needs to be improved in the in-service use process, it is comparatively obvious when maintaining the change to the wing rail that descends in advance because of damaging, because the wing rail is global design, it is loaded down with trivial details hard when leading to maintaining the transport, and can't change alone to wearing and tearing serious position to lead to the higher problem of maintenance cost.
