METHOD OF RAILWAY CAR INNER SURFACE CLEANING OF STUCK OR FROZEN-ON LOOSE MATERIAL AND DEVICE TO THIS EFFECT Russian patent published in 2008 - IPC B65G67/24 B60S3/00 B65G69/20 

FIELD: transport, production engineering.

SUBSTANCE: method of railway car inner surface cleaning of stuck or frozen-on loose material consists in that the inductors incorporating indentors. The inductor reaction force is perceived by bumper (8) pressed at 0.5 to 10 kN to the car surface, the said force being controlled by pickups. The bumper (8) working position signal received, power pulse is fed to the inductor windings. The force between the latter and the indentors varies from 10 to 100 kN to throw the stuck or frozen-on loose material from the car inner surfaces. The device to clean the car side and bottom surfaces incorporates bumper (8) representing a lever hinged to the frame (4), the lever larger arm being fitted with weight (9) and its smaller arm being provided with a block housing the inductor (2) and indentor (3). The bumper is forced into its initial position by power cylinder (11).

EFFECT: higher efficiency.
