Abstract
The utility model relates to a high manganese steel frog with a special structure, which can avoid a harmful space in a high manganese steel frog. The frog comprises a high manganese steel frog, wherein a double-throat frog of the high manganese steel frog is symmetric about a center of the double-throat frog, and a reverse access turnout impact angle of the double-throat frog is zero degree. The frog provided by the utility model has the advantages that: 1, the distance of the harmful space in the frog is shortened, the smoothness of the frog is strengthened, the contact area of a wheel is enlarged, the wear to the frog can be relieved or slow down, and further, the whole service life of the frog and riding comfortableness can be improved; 2, the double throats are symmetric about the center of the frog, so that the traveling safety of a vehicle is ensured; 3, the reverse frog feed impact angle of the double-throat frog is reduced to zero degree, so that the turnout passing smoothness of the wheel can be increased; 4, the frog has a simple double-throat structure, is easy to forge and process; and 5, the double-throat structure of the frog can shorten the distance of the harmful space in the frog by about 1/2, and can strengthen the smoothness of the frog.
Description
Technical field
The utility model relates to a kind of high manganese steel frog that can avoid a kind of special construction of high manganese steel frog idle space, belongs to high manganese steel frog and makes the field.
Background technology
Railway frog is to make wheel by the path at grade intersection equipment of one rail through another strand rail, can be divided into fixed railway frog and movable-point crossing according to the structure of heart rail.Railway frog is as a critical component of track switch, the application life and the overall trip speed that directly affect track switch.Speed per hour more than 200 kilometers with the quasi high-speed section track laying of part movable-point crossing, all the other circuits generally use the fixed solid manganese steel frog.The fixed solid manganese steel frog has the following advantages: the one, and good integrity, upper track is changed convenient, safeguards simple; The 2nd, excellent work hardening ability, abrasion resistance is good; The 3rd, good impact toughness, if crackle, crack propagation velocity is slow; The 4th, advanced explosion hardening technology is adopted on the driving surface, further improves the railway frog abrasion resistance; The 5th, adopt one section common rail of stainless steel medium welding at the high manganese steel frog two ends before dispatching from the factory, to satisfy the requirement of gapless track field Welding.But there is inevitable idle space in the fixed high manganese steel frog, and path interrupts, and has irregularities how much, causes producing through train rocking, and not only makes passenger's ride quality poor, has also quickened the abrasion of railway frog, reduces railway frog application life.Therefore, need the structure at gap in the frog position is optimized, alleviate or alleviate its influence the railway frog whole service life.
The utility model content
The purpose of design: avoid the weak point in the background technology, design a kind of high manganese steel frog that can avoid a kind of special construction of high manganese steel frog idle space.
Design scheme: in order to realize above-mentioned purpose of design.The utility model is researched and developed the new structure at a kind of gap in the frog position---two throat structures; Shorten the distance of gap in the frog; Reversely advance to branch off the angle of shock and be decreased to 0 °; So both strengthen the railway frog ride comfort, alleviated or delayed the abrasion of railway frog again, thereby improved the whole service life of railway frog and the comfort level of riding.On structure design, the two throat structures of high manganese steel frog are meant the former throat of railway frog parallel to theoretical tip direction extension (see figure 1).
Technical scheme: a kind of high manganese steel frog of special construction, it comprises high manganese steel frog, two throat railway frog centers symmetry in the said high manganese steel frog, it is 0 ° that two throat structure railway frogs reverse advances to branch off the angle of shock.
The utility model is compared with background technology, and the one, the distance of shortening gap in the frog strengthens the railway frog ride comfort, increases the contact area of wheel, alleviates or delay the abrasion of railway frog, thereby improves the whole service life of railway frog and the comfort level of riding; The 2nd, two throats should have been guaranteed travel safety about railway frog center symmetry; The 3rd, two throat structure railway frogs reverse advances to branch off the angle of shock and is decreased to 0 °, strengthens wheel and crosses the trouble ride comfort; The 4th, the two throat structure designs of railway frog are simple, are easy to casting and machine; The 5th, the two throat structures of railway frog can either shorten idle space distance about 1/2, strengthen the railway frog ride comfort again.
Description of drawings
Fig. 1 is the sketch map of two throat structures in the high manganese steel frog of special construction.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of high manganese steel frog of special construction, it comprises high manganese steel frog, two throat railway frog centers symmetry in the said high manganese steel frog, it is 0 ° that two throat structure railway frogs reverse advances to branch off the angle of shock.Its method for designing: it comprises high manganese steel frog, and the two throat structures of said high manganese steel frog are meant the former throat of railway frog parallel to theoretical tip direction extension, shorten the distance of gap in the frog, strengthen the railway frog ride comfort, increase the contact area of wheel.Said idle space reduced distances 40%-60%.
What need understand is: though the foregoing description is to the mentality of designing of the utility model detailed text description of contrasting; But these text descriptions; Just the simple text of the utility model mentality of designing is described; Rather than to the restriction of this exposed installation meter thinking, any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the utility model.
Claims (1)
1. the high manganese steel frog of a special construction, it comprises high manganese steel frog, it is characterized in that: it is 0 ° that two throat railway frog centers symmetry in the said high manganese steel frog, two throat structure railway frogs reverse advance to branch off the angle of shock.
