Description

Technical Field

[0001] The utility model relates to the technical field of frog equipment, in particular to a frog which is convenient for partial replacement. Background Art

[0002] A frog, also called a turnout, is a line connection device that allows locomotives and vehicles to transfer from one track to another. It is also one of the weak links of the track and is usually laid in large quantities at stations and marshaling yards. With a turnout, the line's capacity can be fully utilized. Even for a single-track railway, laying a turnout and building a fork line that is longer than the length of the train will allow trains to run in opposite directions. Turnouts play an important role on railway lines. The main structures of existing alloy steel frogs include forged alloy steel heart rail combination frogs, alloy steel rail combination frogs, and welded wing rail reinforced alloy steel combination frogs. The wing rails of these three types of frogs retain the shape of the rails, and the vulnerable position is an integrated structure with the wing rail body. When the vulnerable part fails, it cannot be replaced separately.

[0003] In order to solve the above problems, a Chinese utility model patent with authorization announcement number CN218861229U discloses a partially replaceable frog. The frog body and the insert core of the device are detachable and assembled, and the vulnerable parts can be quickly replaced online and offline, saving costs while meeting usage requirements.

[0004] However, in actual use, when the inlay is damaged and needs to be replaced, the frog part needs to be completely removed from the track, the T-bolts can be unscrewed, and then the inlay can be removed, which is cumbersome and inconvenient to replace. Utility Model Content
