Example 1
In the process of leveling coal, the scraper of the coal leveling device of the railway carriage carries out lifting movement, and the scraper can receive the thrust in the horizontal direction of the coal pile when descending to the position of the coal pile, so that stress analysis is required to be carried out on each structure when designing the coal leveling device, and a protection mechanism is additionally arranged on a key stress mechanism through an analysis result so as to prevent the coal leveling device from being damaged due to overlarge stress. In the coal charging process, the heights of the coal piles are inconsistent due to the fact that manual operation and coal quality change, the horizontal thrust force borne by the scraping plates is different due to the influence of the heights of the coal piles, if the coal piles are very high, the horizontal thrust force borne by the scraping plates is large and easily exceeds the limit load force borne by the coal leveling device, and the coal leveling device is damaged; when the scraper blade finishes the coal leveling operation, if the scraper blade can not rise for a certain reason, the problem that the scraper blade directly collides with a railway carriage to cause safety accidents can occur. In order to solve the problems, the prior art adopts a scheme of additionally installing a proximity sensor mechanism, when a spring plate touches a carriage, a scraping plate rises immediately, but when a coal pile is too high, the proximity sensor mechanism is easy to submerge, and after the coal pile is in the state for a long time, the proximity sensor mechanism can be blocked and can not be used continuously.

In the practical application process, under the normal running condition, the train runs below the main body, and the scraping plates are fixed and partially extend into the carriage to level the coal pile.
