Abstract
The utility model relates to a novel structure of a high manganese steel frog point rail, which not only can reliably bear a huge alternating shock load of wheels, but also can ensure that the top surface of the rail is difficult to strip and chip. The novel structure comprises the high manganese steel frog point rail; the high manganese steel frog point rail is uniformly and gradually widened to 6mm from a place from 80 mm to an actual tip; and the obliquity of a working edge is gradually transited from 1:5 to 3:8. The utility model has the advantages that 1, the high manganese steel frog point rail structure is optimized, the contact form of the top surface of the point rail is improved, and the service life of a frog is prolonged; 2, the actual tip of the frog point rail is widened by 40 percent, so that effective contact area of the point rail is obviously enlarged, the strength of a small cross section of the point rail is enhanced, the wear resistance of the point rail is improved, and the whole service life of the frog is prolonged; 3, the widened structure of the high manganese steel frog point rail is easy to design and easy to cast and machine; and 4, the novel structure provides safety guarantees for high-density, large-traffic-volume and great-axle-load railways with passengers and freight traffics.
Description
Technical field
The utility model relate to a kind of can either the huge alternating shock load of anti-reliably wheel, can guarantee that again the tread face is difficult for producing a kind of novel high manganese steel frog heart rail structure of flake-off piece, belong to high manganese steel frog heart rail and make the field.
Technical background
Along with fast development of national economy, railway operation speed improves day by day, and the track switch of using on the circuit is had higher requirement.Railway frog is as a critical component of track switch, the application life and the overall trip speed that directly affect track switch.Potassium steel is widely used in the railway frog manufacturing with its excellent shock peening performance, high strength and good impact toughness as best material.Through effort for many years, China's Quality of High-manganese Steel Frog level improves constantly, and just reached world level through gross weight one hundred million ton in the mid-90 in 20th century application life.But owing to China railways high density, large conveying quantity, heavy, the passenger-cargo specific condition of using with of macro-axis; High manganese steel frog in use; Receive the huge alternating shock load effect of wheel; It is more obvious because of the little flake-off piece of tread contact area that the tread face is prone to produce flake-off piece, particularly heart rail 20～50mm section, becomes railway frog and may wear to one of principal mode of limit inefficacy.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of can either the huge alternating shock load of anti-reliably wheel, can guarantee that again the tread face is difficult for producing a kind of novel high manganese steel frog heart rail structure of flake-off piece.
Design scheme: for realizing above-mentioned purpose of design.The utility model through theoretical demonstration and experiment repeatedly, is widened processing with heart rail working edge on structure design, increase the contact area of heart rail, strengthens the light-gauge intensity of heart rail, thereby improves the abrasion resistance of heart rail and the whole service life of railway frog.Its core is: high manganese steel frog heart rail is widened processing; Heart rail 80mm section is widened 0mm and is transitted to actual tip gradually and widen the 6mm (see figure 1); Increase effective contact area of heart rail; The working edge gradient transits to 3:8 gradually by 1:5, strengthens the light-gauge intensity of heart rail, thereby improves the abrasion resistance of heart rail and the whole service life of railway frog.
Technical scheme: a kind of novel high manganese steel frog heart rail structure, it comprises high manganese steel frog heart rail, said high manganese steel frog heart rail 80mm should evenly be widened to 6mm gradually to actual tip; The working edge gradient transits to 3:8 gradually by 1:5.
The utility model is compared with background technology, and the one, optimized high manganese steel frog heart rail structure, improve the contact form of heart tread face, improve the application life of railway frog; The 2nd, the actual tip width of central body of frog widens 40%, obviously increases effective contact area of heart rail, not only strengthens the light-gauge intensity of heart rail, and improves the abrasion resistance of heart rail and the whole service life of railway frog; The 3rd, it is simple that high manganese steel frog heart rail is widened structure design, is easy to casting and machine; The 4th, for high density, large conveying quantity, macro-axis weigh, passenger-cargo mixed fortune provides safety assurance.
Description of drawings
Fig. 1 is the sketch map of novel high manganese steel frog heart rail structure.
Fig. 2 is the actual most advanced and sophisticated structural representation of high manganese steel frog heart rail.
Fig. 3 is the wide structural representation of high manganese steel frog heart rail.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1-3.A kind of novel high manganese steel frog heart rail structure, it comprises high manganese steel frog heart rail, the manufacture craft of high manganese steel frog heart rail is a prior art, is not described herein at this.Said high manganese steel frog heart rail 80mm should evenly be widened to 6mm gradually to actual tip, and promptly heart rail working edge is widened processing, increases the contact area of heart rail, strengthens the light-gauge intensity of heart rail, thereby improves the abrasion resistance of heart rail and the whole service life of railway frog; The working edge gradient transits to 3:8 gradually by 1:5.Said heart rail 80mm section is widened 0mm and is transitted to actual tip gradually and widen 6mm.
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 (2)
1. novel high manganese steel frog heart rail structure, it comprises high manganese steel frog heart rail, it is characterized in that: said high manganese steel frog heart rail 80mm should evenly be widened to 6mm gradually to actual tip; The working edge gradient transits to 3:8 gradually by 1:5.
2. novel high manganese steel frog heart rail structure according to claim 1 is characterized in that: said heart rail 80mm section is widened 0mm and is transitted to actual tip gradually and widen 6mm.
