Description

The utility model relates to the field of railway technology, namely refrigerated cars.

Refrigerated cars equipped with air ducts are known from the prior art, for example a car model 16-3000 (https://stylishbag.ru/19-foto/vagon-termos-chertezhi.html)

A device for heat treatment and ventilation of the cargo space of a refrigerated car is known from the prior art, containing a cooler, a heater, fans located under the ceiling of the car, a longitudinal air duct with outlet holes in the side walls, a floor grille and a circulation channel, characterized in that, in order to increase safety cargo by improving the temperature regime of the car; it is equipped with panels installed along the side walls of the longitudinal air duct at an angle to them (SU 1 090 605, B61D 27/00, B60P 3/20, publ. 05/07/84).

A device for heat treatment and ventilation of the cargo space of a refrigerated car is known from the prior art, containing a cooler, a heater, at least one fan, a longitudinal distribution air duct located under the ceiling of the car, a floor grille and a circulation channel, characterized in that, in order to increase efficiency by to improve the safety of cargo when transporting it with heating, it is equipped with air distribution channels placed in the cavity of the floor grille, and the circulation channel is located below the level of the floor grille and is equipped with guide elements mounted in its lower part and dividing the channel into outlets, the number of which is equal to the number of air distribution channels ( SU 1 004 179, B61D 27/00, publ. 03.15.83).

The disadvantages of the known solutions are the high weight of the car and insufficient carrying capacity.

There is a known method for assembling a railway car, which includes: forming the bottom of a railway car, limited in part by a central beam having a plurality of cross braces, transverse supports and body beams extending from it, together with a first end beam and a second end beam located adjacent to opposite ends of the central beam ; forming a pair of side wall assemblies and a pair of end wall assemblies, each side wall assemblies and each end wall assemblies having an outer metal surface and an inner surface of fiber reinforced material with foam insulation disposed therebetween; forming each sidewall assembly with an opening for loading and unloading cargo; attaching the first sidewall assembly to one side of the subframe of the railroad car; attaching the second sidewall assembly to the other side of the subframe of the railroad car; attaching the first end wall assembly to the first end beam of the railroad car subframe; attaching a second end wall assembly to a second end beam of the railroad car subframe; attaching the roof assembly to the side wall assemblies and end wall assemblies opposite the car subframe; fastening the primary floor assembly to the car subframe; applying insulating material to the respective connections formed between the end wall assemblies and the side wall assemblies, the main floor assembly and the side wall assemblies and the end wall assemblies, and the roof assembly and the end wall assemblies and side assemblies; attaching a door assembly adjacent to a corresponding opening formed in each side wall assembly to control access to the railroad car; and installation of a second floor assembly on the first floor opposite the carriage subframe (US patent 7543367 B2).

The disadvantages of the known solution are the lack of information about the possibility of making the inner lining from light metal, for example aluminum (possibly implying the use of steel sheets), as well as the lack of information about the method of attaching the air duct to the inner lining (possibly implying welding). The use of steel sheets for cladding, as well as connecting the air duct to the internal lining with welded seams increases the weight, and therefore leads to a decrease in load capacity. Other solutions regarding the execution of the internal lining and the connection of the air duct to the lining do not directly follow and are not obvious from the description of the solution (US patent 7543367 B2).

The device (patent No. US 7543367 B2) was chosen as the closest analogue.

The technical problem solved by the proposed utility model is the high weight of the car and insufficient load capacity.

The technical result achieved by the utility model is an increase in load capacity.

The technical result is achieved due to the fact that the refrigerated car contains a body with a frame, and the body contains a frame mounted on the frame, sheets of inner and outer skins and insulation between these sheets, a chassis, automatic coupling devices, braking equipment, doors, an engine room, including refrigeration and heating equipment, an air duct, wherein the air duct, including vertical walls, a lower horizontal shelf and upper horizontal shelves, is rigidly attached inside the body to the sheets of the inner lining and is adjacent to the refrigeration and heating equipment, the air duct is made of aluminum alloy, according to the utility model, the sheets The inner lining is made of aluminum alloy, while the air duct is rigidly attached to the sheets of the inner lining with its upper horizontal flanges using stainless steel rivets, and the distance between adjacent rivets is 50-150 mm.

The claimed utility model is illustrated by drawings:

in fig. 2 - section of the car with a view of the air duct,

in fig. 3 - air duct,

in fig. 4 - fastening the air duct to the inner lining,

The inventive refrigerator car contains a body 1 with a frame 2, while the body 1 contains a frame mounted on a frame 2, sheets of inner 10 and outer 11 cladding and insulation between these sheets, a chassis 3, automatic coupling devices 4, brake equipment 5, doors 6, engine room 7, including refrigeration and heating equipment 9, air duct 8. Air duct 8, including vertical walls 8.1, lower horizontal shelf 8.2 and upper horizontal shelves 8.3, is rigidly attached inside the body 1 with its upper shelves 8.3 to the inner lining sheets 10 and is adjacent to the refrigeration - heating equipment 9. The inner lining sheets 10 are made of aluminum alloy. The air duct 8 is made of aluminum alloy. The air duct is rigidly attached to the inner lining sheets 10 with its upper horizontal flanges using rivets 12 made of stainless steel.

Compared to steel inner lining, making the inner lining 10 and air duct 8 from aluminum alloy makes it possible to reduce the weight of the car and thereby increase the load-carrying capacity of the car. Rigid fastening of the air duct 8 to the sheets of internal cladding 10 using the upper horizontal shelves 8.3 allows you to avoid the installation of additional fastening devices that will increase the weight and reduce the load capacity. Rigid attachment of the air duct 8 to the sheets of the inner lining 10 with its upper flanges 8.3 using stainless steel rivets 12 allows you to reliably fasten the air duct 8 to the inner lining 10, while in comparison with a continuous weld, such a point fastening allows you to reduce weight and increase the load capacity.

The distance between adjacent rivets 12 can be 50-150 mm. A distance of less than 50 mm will not allow saving on weight and increasing the carrying capacity of the car. A distance of more than 150 mm will not allow the air duct to be securely fastened, which will not allow it to be used.

An experimental refrigerated car was manufactured, in which the air duct and internal lining were made of aluminum alloy. The air duct was rigidly attached to the inner lining sheets with its upper horizontal flanges using stainless steel rivets. The distance between adjacent rivets was 95-105 mm. At the same time, the necessary strength of the air duct was ensured; the air duct was securely attached to the inner lining of the car. Calculations showed that, compared to the analogue, the car's carrying capacity increased by 940 kg.

Consequently, the claimed utility model makes it possible to provide a technical result consisting in increasing the carrying capacity of the car.
