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 railway equipment field, particularly relate to a kind of turnout switch of railroad track.
Background technology
Along with the fast development of society, railway is also in the middle of high speed development, and the input of fund is also more and more nervous, under the prerequisite ensureing safety of railway operation, how to extend the life-span of Iron-surfur clusters, is the problem that pendulum is badly in need of solving in face of us.Extend the application life of key railway product, not only can solve the anxiety that railway fund drops in advance, and can save a large amount of maintenance costs and therefore produce affect the problems such as the blockade point that railway normally runs.
Vitals tongue in railway switching machines is the parts the most easily worn away, the employing of the sixties in last century carries out hard surfacing by the wide 10mm section of tongue rail head, by the wide 5mm section of tongue rail head, carry out the quenching of tongue rail head surface to adopting when the eighties, tongue significantly improves application life.But quenching is not implemented to tongue rail head wide 5mm section tip in tongue top, it is in the majority that the point of switch is sawtooth pattern abrasion, and that thus causes tongue descends road in advance.
Summary of the invention
In order to the tongue overcome in traditional railway turnout switch easily weares and teares the problem causing application life short, the invention provides a kind of alloy steel and strengthen tongue.
The technical scheme that the present invention is adopted for achieving the above object is: tongue strengthened by alloy steel, and the point of switch installs panelling, and tongue and panelling are bolted, also bonding by adhesive between the point of switch and panelling; Field joint iron on bolt, installing insulating sheet between connecting iron and straight switch, installing insulating pipe inside connecting iron and between bolt surface, bolt is positioned at mounting nuts outside connecting iron, installing insulating packing ring between nut and connecting iron.
Mounting and adjusting sheet between described tongue and insulating trip.
Between described nut and insulating washer, packing ring is installed.
The panelling of described tongue is bainitic steel.
Tongue strengthened by alloy steel of the present invention, utilize adhesive bonding technique quench section cannot divide the bainitic steel edge carrying out high-strength abrasion-proof point to the point of switch, to improve the application life of newly making tongue, also can scrap tongue to what worn away simultaneously, sawing is except the tip of abrasion, change the tongue sticking into edge point, make it use safer.Panelling technique solves tongue front end because of cannot heat treatment, although or through Overheating Treatment, but limit by material own, locomotive by time bear incessantly huge impact, the common problem of flake-off block is caused at tongue front end place, tongue after panelling reparation, its use will exceed the application life of common new tongue.
Accompanying drawing explanation
Fig. 1 is that tongue structure chart strengthened by alloy steel of the present invention.
Detailed description of the invention
As shown in Figure 1, panelling 1 is installed at tongue 2 tip to alloy steel reinforcement tongue structure of the present invention, and tongue 2 and panelling 1 are fixed by bolt 3, also bonding by adhesive between tongue 2 tip and panelling 1; Field joint iron 6 on the one end of bolt 3 extending tongue 2, installing insulating sheet 5 between connecting iron 6 and straight switch 2, mounting and adjusting sheet 4 between tongue 2 and insulating trip 5.Installing insulating pipe 7 inside connecting iron 6 and between bolt 3 surface, bolt 3 is positioned at mounting nuts 10 outside connecting iron 6, installing insulating packing ring 8 between nut 10 and connecting iron 6, installs packing ring 9 between nut 10 and insulating washer 8.
Within nearly ten years, oneself warp of China can produce high-strength, wear-resisting bainitic steel, within 2009, disclose again engineering machinery high-strength abrasion-proof bainite steel plate national standard, 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 quench section cannot divide the bainitic steel edge carrying out high-strength abrasion-proof point to the point of switch, to improve the application life of newly making tongue, also can scrap tongue to what worn away, sawing is except the tip of abrasion simultaneously, change the tongue sticking into edge point, make it use safer.Panelling technique solves tongue front end because of cannot heat treatment, although or through Overheating Treatment, but limit by material own, locomotive by time bear incessantly huge impact, the common problem of flake-off block is caused at tongue front end place, tongue after panelling reparation, its use will exceed the application life of common new tongue.Alloy steel is strengthened tongue panelling technique and will be extended one of best technique in tongue application life from now on by being.Popularize in an all-round way in the Ministry of Railways, the pressure of railway fund will be alleviated greatly.Will adopt by vast railway user, for the development of railway cause makes a due contribution, also can bring economic benefit widely for enterprise and society.
