TANK-CONTAINER Russian patent published in 2003 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to containers for transportation and storage of liquids and gases and it can be used in railway, road and water transport. Proposed tank-container has tank with convex end plates, two end face rectangular frames consisting of posts and crossmembers connected at corners by angular fittings and at spans, by diagonal braces. Tank-to-end frame fastening system includes at least lower support beams arranged in pairs at each side of tank and secured by some ends of corresponding angular fittings and by other ends, through pad members, on cylindrical part of tank lower than its horizontal axis of symmetry within zones chosen on tank surface with account of minimization of power actions caused by external actions on container, on tank, lower support beams and angular fittings of end face frame. Each zone is arranged between two generatrices of tank cylindrical surface corresponding to angles of 30o and 60o relative to horizontal axis of symmetry of tank and is limited in axial direction by arcs of two circumferences passing along cylindrical surface of tank at distance from corresponding angular fitting measured along longitudinal axis of tank equal to 0.8R and 1.2R, respectively, where R is outer radius of tank. Invention provides reduction of cost of manufacture. EFFECT: improved reliability of tank-container, reduced material usage. 3 dwg
