Embodiment 1

[0052] like figure 1 As shown, the present invention provides a frog assembly 100, comprising: a wing rail 102, a fork heel rail 104 and a core rail 106, wherein the wing rail 102 includes a first wing rail 1022 and a second wing rail 1024; 104 includes a first fork and heel rail 1042 and a second fork and heel rail 1044 .

[0053] Specifically, one end of the first fork heel rail 1042 is inserted at one end of the first wing rail 1022; one end of the second fork heel rail 1044 is inserted at one end of the second wing rail 1024; a core rail 106 is also included, which is arranged on the second wing rail 1024. The first wing rail 1022 and the second wing rail 1024 are located at the junction of the wing rail 102 and the fork heel rail 104 ;

[0054] The frog assembly 100 provided by the present invention includes a wing rail 102, a core rail 106, and a fork heel rail 104, wherein the wing rail 102 includes a first wing rail 1022 and a second wing rail 1024, and the fork heel ...

Embodiment 2

[0057] On the basis of the above examples, if figure 1 and Figure 4 As shown, the frog assembly 100 provided by the present invention may also include: a first spacer iron 110 disposed between the core rail 106 and the wing rail 102; the core rail 106, the wing rail 102 and the first spacer iron 110 pass through the second The connection part 112 is connected.

[0058] Specifically, a first spacer iron 110 is provided between the first wing rail 1022 and the core rail 106 and between the second wing rail 1024 and the core rail 106. Meanwhile, the first wing rail 1022 is connected to the , the second wing rail 1024 , the core rail 106 and the first spacer iron 110 are connected. Through the setting of the first spacer iron 110, when the train passes the frog assembly 100, the first spacer iron 110 acts as a buffer against the impact between the wing rail 102 and the core rail 106, preventing the core rail 106 and the wing rail 102 from Transitional wear improves the service...

Embodiment 3

[0061] On the basis of any of the above-mentioned embodiments, such as figure 1 and Figure 5 As shown, the frog assembly 100 provided by the present invention may also include: a second spacer iron 114 disposed between the first wing rail 1022 and the second wing rail 1024; the first wing rail 1022, the second wing rail 1024 and the second wing rail 1024 The two spacer irons 114 are connected by a third connecting portion 116 .

[0062] Specifically, the second spacer iron 114 is set between the first wing rail 1022 and the second wing rail 1024, so that the size of the second spacer iron 114 can be used to ensure the distance between the first wing rail 1022 and the second wing rail 1024. distance, so as to ensure the installation size of the frog assembly 100, thereby ensuring the stability of the frog assembly 100. Further, the second spacer iron 114 can be arranged at the throat of the first wing rail 1022 and the second wing rail 1024, that is, the minimum distance bet...

Abstract

The invention provides a frog assembly and a turnout structure. The frog assembly comprises wing rails and a fork heel rail, and the wing rails comprise a first wing rail and a second wing rail; the fork heel rail comprises a first fork heel rail and a second fork heel rail, and one end of the first fork heel rail is inserted into one end of the first wing rail; one end of the second fork heel rail is inserted into one end of the second wing rail; a point rail is included, is arranged between the first wing rail and the second wing rail and is positioned at a joint of the wing rails and the fork heel rail; and the point rail is connected with the wing rails and the fork heel rail through a first connecting part. The invention provides the frog assembly. The wing rails, the point rail and the fork heel rail are arranged to be a detachable structure and the three parts are connected and fastened through the first connecting part. Compared with an integrated alloy steel frog, by using thefrog assembly and the turnout structure of the invention, the performance of the frog is guaranteed, meanwhile, casting machining difficulty of the frog assembly is reduced, manufacturing cost of thefrog assembly is decreased, and in addition, a transportation process of the frog assembly can be more convenient through a detachable structural design.

Description

technical field [0001] The invention relates to the technical field of railway tracks, in particular to a frog assembly and a turnout structure. Background technique [0002] In the related technology, the frog in the tramway turnout is an alloy steel frog that integrates the wing rail and the fork center. The integrated structure is difficult to process, the processing cost is high, and the transportation process is inconvenient and the installation efficiency is low. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] Therefore, the first object of the present invention is to provide a frog assembly. [0005] The second object of the present invention is to provide a switch structure. [0006] In view of this, the first aspect of the present invention provides a frog assembly, comprising: a wing rail and a fork heel rail, wherein the wing rail includes a first w...
