TANK BOILER PROTECTIVE SCREEN Russian patent published in 2023 - IPC B61D5/00 

FIELD: railway transport.

SUBSTANCE: invention relates to the design of tank cars for the transport of liquid and gaseous products. The protective screen of the cistern boiler contains a support sheet with stiffening ribs located on the side of the cistern boiler bottom. The support sheet is made bent with the formation of two sections (1.1, 1.2) located at an angle with respect to each other. In one section (1.2), the support sheet is rigidly attached to the tank frame, and in the other section (1.1) of the support sheet, stiffening ribs are made in the form of concentric rings (4) located symmetrically relative to the longitudinal axis of the tank boiler. The height of the stiffening rings decreases from the outer ring to the inner, the thickness of the stiffening rings increases from the outer ring to the inner.

EFFECT: invention improves shock-absorbing properties of the protective screen and its energy efficiency, provides redistribution of shock load over the entire protective screen and absorption of energy from collision with protruding elements of an adjacent car, and also increases the strength and reliability of the screen and simplifies the design.
