Description

FIELD OF TECHNOLOGY

The utility model relates to railway transport, in particular to devices for transporting liquid cargo.

BACKGROUND

There are various technical solutions in this area.

For standard tank-type tank wagons, for example, for tank-wagons 15-9545 (see the link http: //xn--1520-u4d3ahgsb9pe.xn--p1ai/wagon/1638/), the boiler is attached to the spine beam using paws and relies on the support legs. Accordingly, with dynamic longitudinal loads acting on the tank car, the supporting element is a spinal beam.

So known is the design of a tank-type tank car (RU patent for utility model No. 49778, IPC B61D5 / 06, published December 10, 2005) containing a frame, a running gear and a boiler fixed to the frame by pivot sections using clamps, and in the middle parts - with the help of shaped paws connected by special bolts to the paws of the frame. The paws of the frame are fixed on the lateral surfaces of the spinal beam.

A disadvantage of the known design is the low manufacturability, namely, the high complexity of installing the boiler on the frame due to the spatial shaped profile of the legs of the boiler.

A characteristic feature of frameless tank cars is that the boiler accepts all the main types of loads, therefore, a tank frame is not required for such a tank car. Frameless tank wagons, as a rule, are equipped with shortened semi-frames located in cantilever units and serving to transfer loads from the boiler to the running gears and vice versa, as well as for the location of shock-traction devices. This approach allows to reduce the weight of the tank car and increase its carrying capacity. However, since tank wagons are mainly used for the transport of dangerous goods, increased demands are placed on the strength and reliability of the boiler and its support units on the chassis.

Due to the fact that in the process of manufacturing the boiler of a tank car, its shape may differ from ideal, as well as due to the large metal consumption of the design of the boiler supports, in practice there are technological difficulties with welding the boiler's smooth supports to an uneven boiler.

Known RU patent for utility model No. 154206 (IPC B61D 5/00, B61F1 / 02, publ. 08/20/2015) "Support boiler frameless tanks." This technical solution, as the closest to the proposed combination of essential features, is selected as a prototype. The known support of the boiler of a frameless tank containing a frame formed by rigidly connected spine and end beams is characterized in that the frame is provided with a longitudinal support containing vertical sheets reinforced by shelves connected to the spine beam through a horizontal sheet and with the bottom of the boiler through a boiler reinforcing plate .

A disadvantage of the known design is the same problem with welding the boiler supports to the boiler due to the difficulty of connecting the boiler supports to the curved surface of the boiler supports and the high metal consumption of the boiler support structure.

Thus, the technical problem that currently exists is the technological problems that arise when welding the boiler supports to the surface of the boiler, especially for frameless tank cars. With poor-quality welding, the overall structural strength of the tank car decreases, which leads to a decrease in reliability and increased accident rate during operation of the product.

DISCLOSURE OF THE ESSENCE OF A USEFUL MODEL

The indicated technical problem is solved by means of a tank car containing a boiler assembly with running gears and automatic couplers fixed in cantilever parts of the tank car on two half frames formed by spinal and end beams rigidly connected to each other using longitudinal supports containing sheets connected with the corresponding spinal beam through the upper horizontal sheet of the spinal beam and with the corresponding section of the bottom of the boiler through reinforcing pads, sheets of longitudinal supports the thread is composite, so that they contain lower and upper parts, between the sheets of longitudinal supports install a reinforcing transverse sheet, with each lower part of the longitudinal supports is a protrusion of the side wall of the spinal beam of the half frame, each upper part of the longitudinal supports has a thickness less than the thickness of the lower parts.

Thus, the technical result is to increase reliability and reduce accident rate during operation of the product while reducing the metal consumption of the structure by providing more reliable and high-quality welding of longitudinal supports to the bottom of the boiler. This is achieved through the use of composite different thicknesses of the lower and upper parts of the longitudinal supports, each lower part of which is a protrusion of the side wall of the spinal beam of the half frame, each upper part of which has a thickness less than the thickness of the lower part adjacent to it, and a reinforcing transverse sheet is installed between the lower and upper parts .

The upper parts of the longitudinal supports may be made of two or more sheets.

The upper parts of the longitudinal supports can be installed obliquely towards the boiler.

The use of the integral longitudinal support of the boiler makes it easier and more reliable to carry out the assembly process of the tank car, because parts of the sheet, unlike the whole sheet, it is easier to qualitatively dock and weld to the boiler. The use of different thickness parts of the longitudinal support of the boiler can also reduce the metal consumption of the design of the longitudinal support of the semi-frame, and therefore of the entire tank car as a whole.

BRIEF DESCRIPTION OF THE DRAWINGS

4 - automatic coupler;

5 - longitudinal support of the boiler;

IMPLEMENTATION OF A USEFUL MODEL

As shown in figure 1, the proposed tank car contains a boiler 1 assembled with running gears in the form of bogies 3 and automatic couplers 4. The boiler 1 is fixed in the cantilever parts of the tank car on two half frames 2 formed by spinal and trailer rigidly interconnected beams using longitudinal supports 5.

The longitudinal supports 5 are made integral and contain lower 8 and upper 7 parts (FIGS. 2, 3), connected, for example, by a weld, between which a reinforcing transverse sheet 9 is connected, connected to the corresponding spinal beam through the upper sheet 10 of the spinal beam and with the corresponding a section of the bottom of the boiler through reinforcing pads 6. Each lower part 8 of the longitudinal support 5 has a thickness S and represents a protrusion of the side wall of the spinal beam of the half frame 2, and each upper part 7 of the longitudinal support 5 has a thickness s less than the thickness S. Thus, the thickness s of each upper 7 part is less than the thickness S of the lower 8 part adjacent to it.

In the shown embodiment, in the longitudinal support 5, single-component upper parts 7 are made, however, it is also possible to use upper parts consisting of two or more sheets. In addition, in the shown embodiment, the upper parts 7 of the longitudinal supports 5 are mounted strictly vertically, but they can be installed obliquely towards the boiler 1 relative to the lower parts 8 for easier docking to the boiler and more efficient welding to the boiler. When the upper parts 7 are made of two or more sheets, these sheets can be installed vertically, or at an angle to the side of the boiler 1.

The use of composite longitudinal supports of the boiler, consisting of lower parts, each of which is a protrusion of the side wall of the spinal beam of the half frame, and upper parts, each of which has a thickness less than the thickness of the lower parts adjacent to them, as well as the installation between the lower and upper parts of the longitudinal support reinforcing transverse sheet allows easier and more reliable to carry out the assembly process of the tank car, because parts of the longitudinal support, in contrast to the integral longitudinal support, with their lower metal consumption provide a simpler, but at the same time better and more reliable joining and welding of sheets of the longitudinal support to the boiler. Accordingly, the present utility model provides a technical result in the form of increasing reliability and reducing accident rate during operation of a tank car while reducing the metal consumption of its structure.

Thus, the proposed tank car has improved technical characteristics compared to known structures.
