Abstract
The utility model provides a C-shaped guard rail steel for railway frog which has horizontal upper and lower end faces, straight work edge, and symmetrical C-shaped cross-section in respect to horizontal center line, the utility model as section bar for production of guard rail of railway frog, compared with the normal guard rail production method, has advantages of saving metal material, high production efficiency, low cost and long lift time. And compared with H-shaped guard rail steel in the present technology, cross-section has simple shape, facilitate production and processing, and less cross section material in the same service performance for central shaft has long distance from working edge.
Description
Technical field
The utility model relates to railroad frog shaped steel, is specifically related to a kind of railroad frog C type guard rail steel.
Background technology
At present, be used for the guard rail of railroad frog, generally adopt common rail by mach means moulding, there is two subject matters, the one, be that raw material processing guard rail need excise unnecessary part with common rail, not only cause waste of material, and production efficiency is low; The 2nd, because the working edge of guard rail is a side of common rail head of rail, in case this working edge wear and tear overrun is promptly scrapped, application life is short.For solving with common rail is that raw material is produced the problem that guard rail exists, the applicant's application number is the patent application formerly of 200620127538.X, a kind of " railroad frog H type guard rail steel " is provided, with this guard rail steel is raw material, by simple metal processing is plastic railroad frog guard rail, has not only saved metal material and processing charges, has also improved the production efficiency of guard rail, and because the working edge of symmetrical structure is interchangeable, the application life of also effectively having improved railway counter-rail.
Summary of the invention
The purpose of this utility model is to make full use of the design advantage that above-mentioned H type guard rail steel is had, when keeping the characteristics that it is easy to process, production efficiency is high, working edge has interchangeability, provide a kind of structure simpler, save the railroad frog C type guard rail steel of material more.
The technical scheme that realizes above-mentioned purpose is: a kind of railroad frog is with C type guard rail steel, it is characterized in that this guard rail steel puts working edge and with respect to horizontal center line laterally zygomorphic " C " tee section for having the upper and lower end face of level and erecting.
The utility model is compared with the mode that adopts common Rail Production guard rail as the section bar of producing the railroad frog guard rail, has to save that metal material, production efficiency height, cost are low, the characteristics of long service life.And with respect to H type guard rail steel, its cross sectional shape is simple, production and processing is convenient, and because its neutral axis is big with respect to the working edge distance, under identical military service performance condition, the section material consumption still less.
Description of drawings
Accompanying drawing is this railroad frog C type guard rail steel cross sectional view.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, this railroad frog with C type guard rail steel for having the upper and lower end face of level 1 and perpendicularly putting working edge 2 and with respect to horizontal center line laterally zygomorphic " C " tee section.
Claims (1)
1, a kind of railroad frog is characterized in that with C type guard rail steel: this guard rail steel is put working edge (2) and with respect to horizontal center line laterally zygomorphic " C " tee section for having the upper and lower end face of level (1) and erecting.
