Abstract
The invention relates to a novel structure of a fixed type high manganese steel integrated cast frog. The novel structure comprises the high manganese steel integrated cast frog, a transverse bar and longitudinal bar combined box type structural design is adopted on the frog, a longitudinal bar structure is adopted on a point rail large section, and transverse bar structures are adopted on the rest. The novel structure has the advantages that the transverse bar and longitudinal bar combined box type structural design is adopted on the frog, the overall strength of the frog is improved effectively, and the impact resistance of the frog is strengthened; and due to the specially designed transverse bar structures of the frog, the operability of the casting process is enhanced, casting defects inside castings are reduced and even eliminated, the quality inside frog treads can reach 1-2 levels after X radiograph test, tissue compactness is improved, and therefore abrasion resistances of point rails and wing rails are enhanced.
Description
Technical field
The present invention relates to a kind ofly can effectively improve the railway frog bulk strength, strengthen the casting technique operability, can reduce and eliminate the casting flaw of foundry goods inside again, 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 make the 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 Symmetries in the described high manganese steel frog, it is 0 ° that two throat structure railway frogs reverse advances 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, that section tread corresponding to from throat of frog to the complete stressed section of heart rail that it is characterized in that described wing rail be one section with wheel tread profile and the decline degree of wheel is complementary during by this section convex surface, described heart rail from actual most advanced and sophisticated that section tread that begins stressed section to heart rail of heart rail be one section therewith section wing rail end face keep the rising curved surface of necessary relative relief, heart rail to begin stressed section from heart rail be one section straight curved surface to that section tread of the complete stressed section of heart rail.
Two throat structures, tread face structure, overall structure force analysis and the structure that the above-mentioned background technology relates separately to the fixed high manganese steel frog is on impact of casting technique etc.
Summary of the invention
Purpose of design: design and a kind ofly can effectively improve the railway frog bulk strength, strengthen the casting technique operability, can reduce and eliminate the casting flaw of foundry goods inside again, improve railway frog tread internal soundness and dense structure's property, improved widely 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 on structure design, and the box-structure that the fixed solid manganese steel frog adopts horizontal bar, vertical muscle to combine designs, and the large section of heart rail adopts vertical muscle structure, and all the other are horizontal bar, improve the railway frog bulk strength; Horizontal bar only is connected with flangeway bottom 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 foundry goods inside, improve the compactness of railway frog internal soundness and tissue, strengthen the abrasion resistance of railway frog, thereby 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 the solid manganese steel frog adopts horizontal bar, vertical muscle to combine, the large section of heart rail adopts vertical muscle structure, and all the other are the horizontal bar structure.
The present invention compares with background technology, and the one, the box-structure that railway frog adopts horizontal bar, vertical muscle to combine has improved the railway frog bulk strength, strengthens the railway frog impact resistance; The 2nd, the horizontal bar structure of railway frog particular design, strengthen the operability of casting technique, reduce and eliminate the casting flaw of foundry goods inside, railway frog tread internal soundness can reach 1～2 grade through microradiography X, improve the compactness of tissue, thereby strengthened the abrasion resistance of heart rail, wing rail.
