Abstract

The utility model provides a combination rail, belongs to mechanical technical field. Including a railhead and a rail body, this set device is symmetrical structure, adopts the alloy material, the rail body that excel in through independent design, the railhead that adopts railhead and rail body because of easy wearing and tearing and adopts low strong base metal material, railhead and the unique configuration design of rail body to make a series of technical measures such as the two perfect combination because of easily losing the utility model discloses a technique can realize that the rail to the perfect matching of strong degree and toughness, has low in production cost, characteristics such as strong degree is high, toughness good, long service life.

Description

A kind of combination rail

Technical field

This utility model belongs to field of mechanical technique, relates to a kind of rail that can combine.

Background technology

Rail be railroad track mainly comprise parts.Its function is that the wheel of pilot engine vehicle advances, and bears The immense pressure of wheel, and be delivered on sleeper.Rail is necessary for wheel to be provided continuously, smoothes out and the rolling table of resistance minimum Face.For making rail will not be depressed or wear away too fast, rail should have enough intensity and hardness, but hardness is the highest, and rail is subject to Easily causing the web of the rail to be lost during impact, therefore, rail should have certain toughness, and traditional rail is an entirety, therefore Hardness can not get both with both toughness.To this end, JP sends out a kind of combination rail, patent device is owing to using rail head and rail body Independent design, rail head uses high-strength alloy material, and to ensure that rail head has high strong hardness and good wearability, rail body is adopted With low strong ordinary metallic material, to ensure that the configuration design that rail body has good impact flexibility, rail head and rail body unique can So that the two is organically combined, such that it is able to realize rail to strong hardness and the purpose of toughness Perfect Matchings.

Summary of the invention

The purpose of this utility model is open one combination rail.

The technical solution of the utility model is realized in.

Combination rail is made up of a rail head and rail body two parts.

Rail head alloy material makes, and for shoulder pole shape solid construction, is X font along cross-sectional view, and described X font is by upper Under two isosceles trapezoids being arranged symmetrically with combine, the minor face of two described isosceles trapezoids is close to each other and has a spacing From, it is used for assigning rail body.

Rail body ordinary metallic material makes, and for Openworks shape structure, described rail body is become through flexural deformation by I-steel, Keeping constant along cross-sectional view, the base of described I-steel and waist, the two ends, left and right of top margin curve an obtuse angle respectively inwards, Forming the screens groove of an isosceles trapezoid, the shape of described rail body screens groove is similar to the shape of described rail head isosceles trapezoid, institute The screens groove stating rail body should be slightly larger than the isosceles trapezoid of described rail head, in order to assign described rail head, it is achieved described rail head and institute The screens stating rail body connects.

Design principle: it is low strong general that rail head uses high-strength alloy material, rail body to use because easily losing because of easy to wear Logical metal material, to ensure that rail body has good toughness, the two can have been carried out by rail head with the configuration design of rail body uniqueness U.S. combination.

This utility model has a characteristic that

Owing to this device uses rail head and the independently combinable design of rail body, on the one hand rail head uses alloy material to make, and Rail body then can use ordinary metallic material to make, and has saved the consumption of alloy material, and rail head become can with the thin pieces of through hardening, Convenient processing and heat treatment, as long as the joint length of rail head is carried out lengthening the effect that i.e. can reach common overlength rail simultaneously, right The joint length of rail body can be not required, and therefore, production cost is relatively low；

Owing to this device uses rail head and the independent design of rail body, rail head uses high-strength alloy material, to ensure rail head Having high strong hardness and good wearability, rail body uses low strong ordinary metallic material, good to ensure that rail body has Toughness, it is thereby achieved that rail is to strong hardness and the Perfect Matchings of toughness；

Owing to this device uses rail head and the independent design of rail body, rail head uses high-strength alloy material because of easy to wear, Rail body uses low strong ordinary metallic material because easily losing, and to ensure that rail body has good toughness, rail head is unique with rail body Configuration design the two can be carried out perfect combination, therefore, the service life of rail head and rail body is all extended.

By this utility model Patent equipment, it is achieved that rail, to strong hardness and the purpose of toughness Perfect Matchings, has life Produce the features such as low cost, strong hardness height, good toughness, length in service life.

Five, detailed description of the invention:

Below in conjunction with embodiment, this utility model is described in further detail.

Combination rail is made up of 1, rail body 2 of a rail head.

Assembling process: as shown in Figure 1-Figure 3, first by described rail body 2 horizontal positioned, then by a described rail head In the 1 screens groove being horizontally inserted described rail body 2, so, package unit is completed, and can come into operation.

Lay skill: in view of principle of expanding with heat and contracting with cold, between two adjacent described rail bodies 2, certain gap should be left, Gap between two adjacent described rail heads 1 can be widened during summer, can be by two adjacent described rail heads 1 during winter Between gap shrinks, to ensure traffic safety.

By embodiment it can be seen that combination rail has that production cost is low, strong hardness is high, good toughness, service life are long Etc. feature.
