Abstract
The invention relates to a method for improving locomotive wheel-rail adhesion. Specifically, high pressure hot wind is utilized to blow and dry a rail surface, the exit temperature of the high pressure hot wind is not lower than 100DEG C, the difference between an exit wind speed and a locomotive speed is not less than 50m/s. The method substantially improves the operating effects of the locomotive in rain, fog, frost, thin ice and other environments, and has obvious economic and social benefits.
Description
Technical field
The present invention relates to a kind of method of improving the wheel drive track adhesion, belong to the railway locomotive technical field.
Background technology
The operation of locomotive is to utilize the creep that produces between wheel and the rail, and the friction force promotion locomotive that creep produces advances or brakes.After the locomotive manufacturing was finished, the weight of locomotive is also just fixing accordingly no longer to have changed, and determines the factor of locomotive traction/braking force size to have only the adhesion factor of locomotive so.The factor that influences the locomotive adhesion factor is a lot, the material of the difference in the build guality of locomotive, wheel footpath, the property difference of traction electric machine, track quality, wheel track, axle such as heavily shift at the utilization that all can influence locomotive adhesion factor or locomotive adhesion factor, wherein, the rail level state is very big to the influence of adhesion, dry rail level adhesion factor height, and drizzle reduces adhesion factor, and track has mist, thin ice, leaf etc., and adhesion factor obviously descends.Environmental aspect between the wheel track is very big to wielding influence of the locomotive tractive effort.
Various kinds of vehicles generally adopts stucco to improve the adhesion factor of locomotive for many years, at four jiaos of bogie trucks or an end of locomotive locomotive sandbox and sanding device is set.Because the locomotive space is limited, so the capacity of locomotive sandbox also can be restricted.And under environment inclement weathers such as light rain, mist, frost, locomotive can frequently dally, stucco.But sand is under the influence of environment such as mist, frost, and the adhesion effect is not desirable especially.And, because long-term stucco can cause the wheel track surface to produce pitted skin, reduce the locomotive adhesion.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, a kind of method of improving the wheel drive track adhesion is provided, under environment atrocious weather situations such as light rain, mist, frost, the frequency that can reduce locomotive wheel spin and slide, reduce ramp parking equivalent risk, improve traction, the braking force of locomotive.
The object of the present invention is achieved like this: a kind of method of improving the wheel drive track adhesion is characterized in that with high-pressure hot wind raceway surface being purged oven dry handles.
In order to realize purpose of the present invention better, the temperature out of above-mentioned high-pressure hot wind is not less than 100 ℃, and the difference of outlet wind speed and the speed of a motor vehicle is not less than 50m/s.
Adopt the solution of the present invention, locomotive will obviously improve in the operational effect of environment such as rainwater, fog, frost, thin ice, has tangible economic and social benefit.
Description of drawings
Fig. 1 is the high-pressure hot wind principle of device scheme drawing of the embodiment of the invention.
Be labeled as among the figure: the total reservoir of 1-, 2-reducing valve, 3-heating resistor band, 4-heating chamber, 5-outlet.
The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Referring to Fig. 1, the high-pressure hot wind device is by total reservoir 1, reducing valve 2, heating chamber 4, heating resistor band 3 and export 5 and form.3 pairs of air that enter heating chamber 4 of heating resistor band heat, and the heating resistor band can be divided into several groups, drops into and excises by contactless switch.Outlet at device is provided with the temperature sensor (not shown), gathers outlet air temperature, and temperature data is fed back in the control microcomputer, and input and the excision of control heating resistor guarantee that outlet air temperature is not less than 100 ℃.
Air after the heating is dried raceway surface through being installed in four angle upcast ventilation pipes of engine truck, and high pressure purges, and makes raceway surface reach dry degree as far as possible.Consider the influence of the speed of a motor vehicle, by the pressure sensor (not shown) pressure data fed back in the control microcomputer that the air pressure of control heating chamber guarantees that the difference of outlet wind speed and the speed of a motor vehicle is not less than 50m/s.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
Claims (2)
