[0028] like Figures 1 to 5 As shown, the railway turnout slide bed 1 of the present embodiment includes a bottom plate 11, a table plate 12, a guide iron 21 and an iron seat 3, the table plate 12 and the iron seat 3 are respectively arranged on the surface of the bottom plate 11, and the bottom plate 11 and the table plate 12 are cast as one piece; a pressing tongue 14 is formed on the side of the table plate 12 facing the iron seat 3, and a cavity 13 for inserting a spring piece is provided between the table plate 12 and the bottom plate 11 along the length direction of the slide bed 1, and the cavity 13 is connected to the bottom surface of the bottom plate 11; it also includes a packaging plate 2, the iron seat 3 is formed on the packaging plate 2, the shape of the packaging plate 2 matches the cavity 13, and the packaging plate 2 is used to be embedded in the cavity 13.

[0029] The working principle of the slide bed 1 is consistent with the working principle of the slide bed 1 in the prior art. The pressing tongue 14 of the table 12 is used to rigidly buckle the rail. The spring piece is fixed to one side of the rail and penetrates the cavity 13 to fix and position the rail. It should be noted that the iron seat 3 can be cast as a whole with the base plate 11 and the table 12 or the iron seat 3 can be welded to the base plate 11 according to actual needs.

[0030] It can be understood that the slide bed 1 structure is formed by integrally casting the bottom plate 11 and the table plate 12, which effectively avoids welding operations, reduces processing steps, and avoids defects caused by welding; by setting the packaging plate 2, the guide iron 21 structure is formed on the packaging plate 2, so that the structure of the cavity 13 is streamlined, and the complete slide bed 1 structure can be obtained by only embedding and assembling the packaging plate 2 into the cavity 13, which not only avoids the problem of difficult processing and molding of the complex structure in the cavity 13, but also reduces casting defects, while ensuring structural strength, and the processing and assembly operations are simple, the structure is streamlined and reasonable, and the service life is improved.

[0031] In this embodiment, the thickness of the packaging plate 2 matches the thickness of the bottom plate 11, the surface is flat after installation, and the overall structural strength is guaranteed;

[0032] In this embodiment, a limiting hole for inserting a pin is opened on one side of the table 12 away from the iron seat 3. After the spring sheet is inserted into the cavity 13, the pin is inserted into the limiting hole so that the pin is pressed on the spring sheet to increase the buckling pressure of the spring sheet and ensure stability.

[0033] In this embodiment, the bottom plate 11 and the packaging plate 2 are respectively matched with positioning structures. By setting the positioning structures, the packaging plate 2 is inserted into the cavity 13 and positioned in place, so that the structure is stable and the assembly is simple.

[0034] Specifically, the positioning structure includes a step structure 15 of a preset length opened on the bottom surface of the bottom plate 11 and on both sides of the cavity 13, and the positioning structure also includes a convex eave 23 formed on both sides of the packaging board 2 and matching the width and length of the step structure 15. After the packaging board 2 is embedded in the cavity 13, the convex eave 23 abuts against the step structure 15 to achieve positioning;

[0035] Furthermore, the positioning structure also includes positioning protrusions 22 formed on both sides of one end of the packaging plate 2 and a positioning groove opened on the bottom plate 11. The shape of the positioning groove matches the positioning protrusion 22. The positioning function is achieved by setting the positioning protrusion 22 and the convex eaves 23 together, and the assembly is more stable.

[0036] In this embodiment, the width of the platform 12 matches the width of the bottom plate 11 , which effectively improves the strength of the slide bed 1 .

[0037] In this embodiment, mounting holes are respectively provided on both sides of the bottom plate 11 for connecting with the switch sleepers through bolts.

[0038] In some embodiments, the iron guide 21 structure is formed on one side of the surface of the packaging board 2 so that its side wall is flush with the side wall of the packaging board 2, simplifying the structure and ensuring structural strength. The iron guide 21 structure can be a trapezoid or a triangle to guide the spring.
