Abstract
The invention relates to a special-structure high manganese steel frog capable of avoiding harmful gaps of the special-structure high manganese steel frog and a design method. The special-structure high manganese steel frog comprises a high manganese steel frog, double throats of the high manganese steel frog are in central symmetry, and a reverse fork entering punching angle of the frog in double-throat structure is 0 degree. The special-structure high manganese steel frog has the advantages that firstly, the distance of a harmful gap of the frog is shortened, smoothness of the frog is improved, contact area of wheels is increased, and abrasion of the frog is alleviated or delayed, therefore the integral service life of the frog is prolonged and riding comfortableness is improved; secondly, the double throats are in central symmetry relative to the frog, and running safety is guaranteed; thirdly, the reverse fork entering punching angle of the frog in the double-throat structure is reduced to 0 degree, smoothness of wheels passing the frog is improved; fourthly, the double-throat structure of the frog is simple in structural design and easy to be cast and machined; and fifthly, by means of the double-throat structure of the frog, about one second of the distance of the harmful gaps can be shortened, and the smoothness of the frog is further improved.
Description
Technical field
The present invention relates to a kind of high manganese steel frog and the method for designing that can avoid a kind of special construction of high manganese steel frog idle space, belong to high manganese steel frog and make 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.
Summary of the invention
The purpose of design: avoid the weak point in the background technology, design a kind of high manganese steel frog and the method for designing 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 present invention researches and develops 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 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.
Technical scheme 2: a kind of high manganese steel frog method for designing of special construction; It comprises high manganese steel frog; 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.
The present invention compares 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.
Embodiment 2: on the basis of embodiment 1; A kind of high manganese steel frog method for designing of special construction; 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 present invention detailed text description of contrasting; But these text descriptions; Just the simple text of mentality of designing of the present invention is described; Rather than to the restriction of this exposed installation meter thinking, any combination, increase or modification that does not exceed mentality of designing of the present invention all falls in protection scope of the present invention.
Claims (3)
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.
2. the high manganese steel frog method for designing of a special construction; It comprises high manganese steel frog; It is characterized in that: 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.
