The biggest difficulty of the 45-foot tank container is also the biggest difference from the 40-foot tank container in the design of the frame, and according to the relevant standard requirements, the 45-foot tank container is provided with four inner corner fittings at two ends of the length of 40 feet. In order to arrange the inner corner fittings, the inner end frames like the outer end frames need to be arranged, so that the stability of the integral structure of the frame and the safety when the inner corner fittings are used for hoisting can be ensured. However, unlike the outer end frame, in order to ensure the maximum volume of the tank body, the inner end frame cannot be made into a complete four-side frame structure, and each side of the inner end frame must be disconnected from the middle and then directly welded and fixed with the outer cylinder body. However, stress concentration at the welding position is caused, and local overlarge stress is easily caused to deform the outer cylinder body and even tear the outer cylinder body. On the basis, the triangular plate is added, so that concentrated stress is dispersed, and the structural strength of the outer cylinder is ensured.

In the present embodiment, the outer cross beam 32, the outer upright post 33, the transverse tube 42, the vertical tube 43, and the connecting tube 7 are all rectangular tubes. The two lower transverse tubes 42 in the inner end frame 4 are connected, so that the support strength can be increased after the arrangement.

A gooseneck groove 81 is arranged on the lower parts of the end saddle 5, the outer supporting seat 34 and the inner supporting seat 45 of the two supporting frames, and three gooseneck grooves 81 on each supporting frame are mutually aligned in the front-back direction. The gooseneck tunnel 81 is provided to accommodate different container flatbeds in different countries throughout the world.

A plurality of rings of T-shaped steel reinforcing rings arranged at intervals are welded on the inner side wall of the outer barrel of the tank body 1, and a web plate of each T-shaped steel reinforcing ring is welded with the inner side wall of the outer barrel. The diameter of the inner cylinder is increased in order to enlarge the volume of the tank container, but the diameter of the outer cylinder cannot be increased by the same proportion due to the limitation of the standard external dimension width of the container, so that the interlayer space is further reduced. Meanwhile, the inner cylinder body adopts a cold tensile strain strengthening structure, and the interlayer needs to reserve enough allowance for the strengthened inner cylinder body. The angle steel reinforcing ring structure of the original outer cylinder body can not meet the requirements. The T-shaped steel is adopted as the reinforcing ring structure of the outer cylinder body, and the reinforcing rings with different thicknesses are adopted through stress analysis and calculation of the inertia moment of the T-shaped steel, so that the strength of the outer cylinder body can be guaranteed while the height is reduced.

The outer end seal of the rear end of the external pipeline of the tank body 1 is a shallow dish-shaped end seal. In order to ensure the volume, the length of the inner cylinder body is also lengthened to the limit, and the interlayer distance between the front seal head and the rear seal head is also greatly reduced compared with the conventional case. But in order to guarantee the pipeline arrangement of the back head intermediate layer, the outer head of the jar body adopts shallow dish head, for standard 1: the butterfly-shaped end socket of 10, shallow dish-shaped end socket can increase the interbedded space of end socket, provides help for the arrangement of intermediate layer pipeline.

And the four corners of the outer end frame 3 are respectively welded with an inclined strut 82, and two ends of the inclined strut 82 are respectively welded with the outer cross beam 32 and the outer upright post 33.
