Abstract
The present invention relates to one and can effectively improve railway frog bulk strength, strengthen casting technique operability, can reduce and eliminate again the casting flaw of cast-internal, improve the fixed solid manganese steel frog new structure of railway frog tread internal soundness and dense structure's property, comprise solid manganese steel frog, the box-structure design that railway frog in solid manganese steel frog adopts horizontal bar, vertical muscle combines, heart rail big cross section adopts vertical muscle structure, and all the other are horizontal bar structure.Advantage: one is the box-structure that railway frog adopts horizontal bar, vertical muscle combines, and improves railway frog bulk strength, strengthens railway frog impact resistance; Two is horizontal bar structures of railway frog particular design, strengthen the operability of casting technique, reduce and eliminate the casting flaw of cast-internal, railway frog tread internal soundness can reach 1 ~ 2 grade through microradiography X, improve the compactness of tissue, thus strengthen the abrasion resistance of heart rail, wing rail.
Description
Technical field
The present invention relates to one and can effectively improve railway frog bulk strength, strengthen casting technique operability, can reduce and eliminate again the casting flaw of cast-internal, improve the fixed solid manganese steel frog new structure of railway frog tread internal soundness and dense structure's property, belong to solid manganese steel frog and manufacture field.
Background technology
CN202416083U, title " a kind of high manganese steel frog of special construction ", it comprises high manganese steel frog, two throat railway frog Central Symmetry in described high manganese steel frog, and it is 0 ° that two throat structures railway frog reverse enters to branch off the angle of shock.
CN201942958U, title " a kind of stiff frog with high ride ", comprise heart rail, be arranged on the wing rail on heart rail both sides, it is characterized in that described wing rail correspond to from throat of frog to that section of tread of the complete stressed section of heart rail be one section with wheel tread profile and the convex surface that matched by the decline degree of wheel when this section, described heart rail from heart rail actual most advanced and sophisticated to that section of tread of stressed section heart rail be one section therewith section wing rail end face keep the rising curved surface of necessary relative relief, the stressed section from heart rail of heart rail is one section of straight curved surface to that section of tread of the complete stressed section of heart rail.
Above-mentioned background technology relates separately to two throat structures of fixed high manganese steel frog, rail top surface structure, overall structure force analysis and structure to the impact etc. of casting technique.
Summary of the invention
Purpose of design: design one can improve railway frog bulk strength effectively, strengthen casting technique operability, can reduce and eliminate again the casting flaw of cast-internal, improve railway frog tread internal soundness and dense structure's property, greatly increase again the fixed solid manganese steel frog new structure in railway frog application life simultaneously.
Design scheme: in order to realize above-mentioned purpose of design.The present invention is in structure design, and the box-structure that fixed solid manganese steel frog adopts horizontal bar, vertical muscle combines designs, and heart rail big cross section adopts vertical muscle structure, and all the other are horizontal bar, improves railway frog bulk strength; Horizontal bar is only connected with bottom flangeway and both sides wall, strengthen the operability of casting technique, be conducive to railway frog the filling type and solidify of molten steel in casting cycle, reduce and eliminate the casting flaw of cast-internal, improve the compactness of railway frog internal soundness and tissue, strengthen the abrasion resistance of railway frog, thus improve the whole service life of railway frog.
Technical scheme: a kind of fixed solid manganese steel frog new structure, comprise solid manganese steel frog, the box-structure design that railway frog in solid manganese steel frog adopts horizontal bar, vertical muscle combines, heart rail big cross section adopts vertical muscle structure, and all the other are horizontal bar structure.
The present invention is compared with background technology, and one is the box-structure that railway frog adopts horizontal bar, vertical muscle combines, and improves railway frog bulk strength, strengthens railway frog impact resistance; Two is horizontal bar structures of railway frog particular design, strengthen the operability of casting technique, reduce and eliminate the casting flaw of cast-internal, railway frog tread internal soundness can reach 1 ~ 2 grade through microradiography X, improve the compactness of tissue, thus strengthen the abrasion resistance of heart rail, wing rail.

Detailed description of the invention
Embodiment 1: with reference to accompanying drawing 1-6.A kind of fixed solid manganese steel frog new structure, comprises solid manganese steel frog, and the box-structure design that the railway frog in solid manganese steel frog adopts horizontal bar 1, vertical muscle 2 combines, heart rail big cross section adopts vertical muscle structure, and all the other are horizontal bar structure.Railway frog horizontal bar only with bottom flangeway 4 and both sides wall 5 be connected, away from wing rail end face 3.Railway frog tread internal soundness reaches to 1 ~ 2 grade.That is, the box-structure design that fixed solid manganese steel frog adopts horizontal bar, vertical muscle combines, heart rail big cross section adopts vertical muscle structure, and all the other are horizontal bar, improves railway frog bulk strength; Horizontal bar is only connected with bottom flangeway and both sides wall, strengthen the operability of casting technique, be conducive to railway frog the filling type and solidify of molten steel in casting cycle, reduce and eliminate the casting flaw of cast-internal, improve the compactness of railway frog internal soundness and tissue, strengthen the abrasion resistance of railway frog, thus improve the whole service life of railway frog.
It is to be understood that: although above-described embodiment to be contrasted detailed text description to mentality of designing of the present invention; but these text descriptions; just the simple text of mentality of designing of the present invention is described; instead of the restriction to mentality of designing of the present invention; any do not exceed mentality of designing of the present invention combination, increase or amendment, all fall within the scope of protection of the present invention.
