Description

The utility model relates to the field of containers for storage and transportation of liquid, gas or bulk materials and can be used in the construction of tank containers.

A well-known container tank for transporting uncooled liquefied gases, class 2 KTs-25 / 2.0, KTs-25 / 2.0NS (Nizhny Tagil), which includes a cylindrical boiler on which fittings are mounted, shadow protection, control valves and having two bottoms which are fastened through the supporting elements and connecting elements to the end frames and on one of the bottoms there is a manhole with a cover and hardware. In this case, the manhole is installed in the center of the bottom, which does not allow full use of the permissible dimension along the length of the tank container, and the reinforcing elements around the manhole are not installed, which does not allow for a smooth distribution of stresses arising in the design of the boiler of the tank tank under the action of operational loads.

The tank tank for liquefied gases, model TS2000, developed by Azovvagonproekt-KOVS CJSC, in which the manhole is mounted on one of the bottoms below the axis of the boiler, makes it possible to rationally use the permissible dimension along the length of the tank container (see figure . Azovvagonproekt - KOVS CJSC (Mariupol) TS 2000.00.000 TO-01, sheet 39). But the reinforcing elements around the manhole are not installed. The large thickness of the welded elements of the hatch - manhole and bottom boiler does not allow for a smooth distribution of stresses arising in the design of the tank container tank under the action of operational loads (see the drawing. Azovvagonproekt - KOVS CJSC (Mariupol) TS 2000.01.000 SB, section NN).

The proposed utility model solves the technical problem of improving the design of the tank container and ensuring its operability even with significant longitudinal and vertical loads of the tank container.

To achieve the specified technical result, in a tank container, including a cylindrical boiler, on which the fittings, shadow protection, control of the fittings and having two bottoms are mounted, which are attached to the end frames through the supporting elements and corner connecting elements and a manhole is made on one of the bottoms with a lid and attachment hardware, a reinforcing pad is welded on the inside of the boiler to the bottom and manhole in shape that repeats the inner surface of the bottom, while at the end of the pad reinforcing from the side when arch to its bottom chamfer at an angle α provides reinforcement lining thickness at the end equal to half its nominal thickness.

Distinctive features of the proposed tank container are the presence in the boiler of the tank container from the inside of the boiler, a lining welded to the bottom and the manhole that supports the shape of the inner surface of the bottom, while at the end of the lining reinforcing it from the side of the lap, a chamfer is made at the angle α providing the thickness of the lining reinforcing at the end equal to half its nominal thickness.

Thanks to the presence of these signs, the task of improving the design of the tank container and ensuring its operability even with significant loads on the boiler from the product being transported, which is made up of its mass, product vapor pressure and pressure of the hydraulic shock, is being solved.

The proposed container tank is illustrated by the drawings shown in figures 1-3.

Figure 1 shows a General view of the tank container.

Figure 2 shows a view A indicated in figure 1.

In Fig.3 shows a remote element B in the context indicated in Fig.1.

The tank container contains a cylindrical boiler 1, on which the fittings 2, shadow protection 3, control of the fittings 4 and having two bottoms 5 are mounted, which are attached to the end frames 8 through the supporting elements 6 and the corner connecting elements 7. A hatch is made on one of the bottoms 5 hole 9 with a cover 10 and attachment hardware 11. Moreover, on the inside of the boiler, a weld 15 is welded to the bottom 5 by a weld 14 and a manhole 9 by a weld 15 a reinforcing pad 12 in shape repeating the inner surface of the bottom 5. At the end 13 of the pad reinforcing 12 with side welded about the seam 14, a chamfer 16 is made at an angle α, providing at the end face 13 of the lining reinforcing 12 a thickness S / 2 equal to half its nominal thickness S.

The utility model is as follows. The following loads act on the boiler from the transported product:

- mass of the transported product;

- steam pressure;

- the force of water hammer arising during transportation.

All of these loads are first perceived by a reinforcing plate, welded from the inside of the boiler to the bottom and to the manhole, and in shape that repeats the inner surface of the bottom, and then they are transferred to the manhole, while the chamfer at the end of the plate reinforcing from the side of the welding weld it is made to the bottom at an angle α and fulfills the thickness of the lining reinforcing at the end equal to half its nominal thickness provides a smooth distribution of stresses arising in the structure from existing loads.

In addition, the very presence of a reinforcing lining, welded from the inside of the boiler to the bottom and to the manhole, provides with a significant difference in thickness

the manhole and the bottom have a smooth transition and, as a result, a smooth distribution of stresses arising in the structure from existing stresses is ensured.

All of the above solves the problem of improving the tank container and ensuring its operability with significant loads on the boiler from the transported product
