Abstract
The invention relates to an alloy steel reinforced point rail, which is characterized in that a panel is installed on the front end of a linear point rail and a curve point rail, wherein the liner point rail and the curve point rail are fixedly connected with the panel through a bolt, and the front end of the point rail is bonded with the panel through bond; an iron connector is installed on the bolt, an insulation plate is installed between the iron connector and the point rail, an insulation pipe is installed between the inner side of the iron connector and the surface of the bolt, and a nut is installed on the outer side of the iron connector on the bolt. According to the alloy steel reinforced point rail, the part of a sharp end of the point rail, which cannot be quenched, is tipped by bainitic steel with high strength and wear resistance by utilizing a cementing technology, the worn sharp end of a worn rejected point rail also can be cut off and replaced by a tipped point rail, so that the point rail is safer to use. The problems of the panel process that the front end of the point rail cannot bear huge impact when a locomotive passes through the point rail and the front end of the point rail is stripped because the front end of the point rail cannot be thermally treated or is limited by the material per se after being subjected to the heat treatment can be solved, and after the point rail is repaired by the panel, the service life is longer than that of an ordinary new point rail.
Description
Technical field
The present invention relates to the railway equipment field, relate in particular to the turnout switch that a kind of railroad track is used.
Background technology
Along with the fast development of society, also in the middle of high speed development, the input of fund is also more and more nervous, under the prerequisite that guarantees safety of railway operation, how to prolong the life-span of railway product for railway, is the pendulum problem that urgent need solves in face of us.Prolong the application life of railway critical product, not only can solve the anxiety that railway fund drops in advance, and the problems such as blockade point that affect the normal operation of railway that can save a large amount of maintenance costs and therefore produce.
Vitals tongue in the railway switch railway switch is the parts that the most easily wear away, the employing of the sixties in last century begins to carry out hard surfacing by the wide 10mm section of tongue rail head, adopt during to the eighties by the wide 5mm section of tongue rail head to begin to carry out the quenching of tongue rail head surface, tongue obviously improves application life.But quenching is not implemented to the wide 5mm section of tongue rail head tip in tongue top, and it is in the majority that the point of switch is the sawtooth pattern abrasion, thereby causes the road that descends in advance of tongue.
Summary of the invention
For the easy wearing and tearing of tongue that overcome in the traditional railway turnout switch cause short problem in application life, the invention provides a kind of alloy steel and strengthen tongue.
The technical scheme that the present invention adopts for achieving the above object is: alloy steel is strengthened tongue, and the point of switch is installed panelling, and tongue and panelling are bolted, and also pass through polymer adhesive between the point of switch and the panelling; Field joint iron on the bolt, installing insulating sheet between connecting iron and the straight switch, installing insulating pipe between connecting iron inboard and the bolt surface is positioned at connecting iron outside mounting nuts, installing insulating packing ring between nut and the connecting iron on the bolt.
Between described tongue and the insulating trip trimmer is installed.
Between described nut and the insulating washer packing ring is installed.
The panelling of described tongue is bainitic steel.
Alloy steel of the present invention is strengthened tongue, utilize adhesive bonding technique can't quench section divide the bainitic steel edge that carries out high-strength abrasion-proof point to the point of switch, to improve the application life of newly making tongue, simultaneously also can be to the tongue of scrapping that has worn away, sawing is except the tip of abrasion, change the tongue that sticks into the edge point, make its use safer.Panelling technique has solved the tongue front end because of can't heat treatment, although or through Overheating Treatment, but limited by material own, locomotive by the time bear and do not live huge impact, cause the common problem of flake-off piece at tongue front end place, tongue after panelling is repaired, its use will surpass the application life of common new tongue.
Description of drawings
Fig. 1 is that alloy steel of the present invention is strengthened the tongue structure chart.
The specific embodiment
Alloy steel of the present invention is strengthened the tongue structure as shown in Figure 1, the tongue 2 most advanced and sophisticated panellings 1 of installing, and tongue 2 and panelling 1 are fixing by bolt 3, also pass through polymer adhesive between tongue 2 tips and the panelling 1; Extend field joint iron 6 on the end of tongue 2 on the bolt 3, installing insulating sheet 5 between connecting iron 6 and the straight switch 2 is installed trimmer 4 between tongue 2 and the insulating trip 5.Installing insulating pipe 7 between connecting iron 6 inboards and bolt 3 surfaces is positioned at connecting iron 6 outside mounting nuts 10 on the bolt 3, installing insulating packing ring 8 between nut 10 and the connecting iron 6 is installed packing ring 9 between nut 10 and the insulating washer 8.
Oneself warp of China can be produced high-strength, wear-resisting bainitic steel in nearly ten years, announced again engineering machinery high-strength abrasion-proof bainite steel plate national standard in 2009, bainite high-strength degree abrasion-resistant stee intensity can reach 1200Mpa, and hardness reaches 360-440HB, and elongation per unit length is more than 10%.The present invention utilizes adhesive bonding technique can't quench section divide the bainitic steel edge that carries out high-strength abrasion-proof point to the point of switch, to improve the application life of newly making tongue, simultaneously also can be to the tongue of scrapping that has worn away, sawing is except the tip of abrasion, change the tongue that sticks into the edge point, make its use safer.Panelling technique has solved the tongue front end because of can't heat treatment, although or through Overheating Treatment, but limited by material own, locomotive by the time bear and do not live huge impact, cause the common problem of flake-off piece at tongue front end place, tongue after panelling is repaired, its use will surpass the application life of common new tongue.It will be to prolong from now on one of best technique in tongue application life that alloy steel is strengthened tongue panelling technique.Popularize in an all-round way in the Ministry of Railways, will alleviate greatly the pressure of railway fund.Will be adopted by vast railway user, for the development of railway cause makes a due contribution, also can bring widely economic benefit for enterprise and society.
