Abstract
The utility model discloses a grinder of a wheel tread cleaner of a high speed motor train unit, which consists of a steel back (1) of the grinder which can be connected with the tile back stand of the cleaner as well as a friction body (2) made by wear resistant material; the grinder of a wheel tread cleaner of a high speed motor train unit is mainly characterized in that the steel back (1) and the friction body (2) are fixedly connected; the grinder has the characteristics of simple structure, good cleaning effect, and the like. Besides, the adhesion between wheel tracks can be enhanced; a phenomenon of wheel lock sliding under a high speed brake state can be effectively prevented.
Description
Technical field
The utility model relates to a kind of clearing apparatus of rail vehicles wheel tread, is specifically related to a kind of cleaning part of EMU tread cleaner.
Background technology
Continuous lifting along with railroad locomotive running speed, for preventing rail vehicles, particularly speed per hour is that the motor train unit of 200km/h～300km/h are under the high speed braking mode, wheel lockup slides the generation of phenomenon, and wheel tread has been proposed higher cleaning requirement, promptly only at foreign material such as the iron rust on the wheel tread, sand and dust under situation about removing fully, could prevent effectively that the phenomenon that wheel lockup slides from taking place.For this reason, study a kind of wheel tread swabbing pig and seem particularly important for maintenance cart wheel tread cleaning, and grinding is the important composition part in the wheel tread swabbing pig, can descend at mal-conditions such as rain, snow, sand, dirt for motor train unit provide a kind of, thoroughly remove grinding of the foreign material on the wheel tread, the most important thing especially seems.
Summary of the invention
The utility model aims to provide a kind of grinding of simple in structure, the effective EMU wheel tread swabbing pig of cleaning.
The utility model realizes that the technical scheme of its purpose is:
A kind of grinding of EMU wheel tread swabbing pig, by constituting with watt back bracket bonded assembly steel backing of described swabbing pig with by the friction piece that high-abrasive material is made, described steel backing is captiveed joint with friction piece.
After adopting such structure,, and clean foreign material on the tread, thereby it is simple in structure and clean effectively, has realized its purpose that will realize by described friction piece and wheel tread applying because this grindings has only two component set-ups.
The further innovative point of the utility model is:
Described steel backing is captiveed joint by hot-press solidifying is bonding with friction piece.Processing is more convenient like this, and structure is more reliable.
The shape and the wheel tread arc of the wheel tread touching position of described friction piece and described motor train unit are suitable.Adopt such structure, can clean the foreign material on the tread more up hill and dale, the cleaning better effects if.
Described steel backing grinds sub the holder by the sub-holder of first grinding and second and constitutes, and described first grinding holder and sub holder of second grinding are fixedly connected by welding.
After technique scheme was implemented, what the utility model had was simple and reasonable for structure, clean effective, can maintenance cart the cleaning of wheel tread, strengthen characteristics such as wheel and interorbital binding force, be conspicuous.
Description of drawings
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the partial schematic sectional view of Fig. 1;
The specific embodiment
Below contrast accompanying drawing, by the description of the specific embodiment, the utility model is described in further detail.
The specific embodiment is shown in accompanying drawing 1 to 3.
A kind of grinding of EMU wheel tread swabbing pig, this grinding is by constituting with watt back bracket bonded assembly steel backing 1 of described swabbing pig with by the friction piece 2 that high-abrasive material is made, and described steel backing 1 is captiveed joint with friction piece 2.
Described steel backing 1 can be captiveed joint by hot-press solidifying is bonding with friction piece 2; Certainly also can be by mode captive joints such as welding.
The shape of the wheel tread touching position of described friction piece 2 and described motor train unit is made and wheel tread arc shape adapting during fabrication, so more helps the applying with wheel tread.
Described steel backing 1 grinds sub-holder 1-1 by first and the sub-holder of second grinding 1-2 constitutes, and this first grinding asks the 1-1 and second grinding to ask 1-2 to be steel part, and is fixedly connected by welding.
Described friction piece 2 can adopt the High Performance composite friction material, forms by polymer binder and all kinds of filler compacting with tackify, cleaning, wear-resisting functions.Both to have cleaning and tackify function in order reaching, can not to bring the effect that is harmful to loss to wheel tread again, can reasonably match the granularity of types of functionality filler, hardness etc.
The restriction that range of use of the present utility model is not described by this specification sheets.
The utility model first sample is good at the car trial effect.
