Abstract

The utility model relates to railway transport, namely, to a wagon-platforms intended for the carriage of various counter-loads on a closed route and on this basis corresponds to the IPC index B61D 3/00. The wagon-platform, characterized by the fact that it contains trucks, frame, four swap bodies, two of which are equally shorter than the other two, having the possibility to change places with two equally longer ones, and on the platform frame there are four pairs of stationary and eight pairs of folding fitting stops, the location of which residual for attaching swap bodies in any location. The technical result of the utility model is as follows: - swap bodies can hold much more cargo than standard containers, so it is enough to fill only two swap bodies with a load to the full carrying capacity of the platform, using the remaining loading area - for returning two empty bodies; - a flatcar may alternately transport lightweight goods in one side in elongated bodies, and in the other side - heavy in shortened bodies having appropriate structures. - swapping swap bodies, you can place loaded loaded bodies always in the center of the platform, and empty bodies - at the ends of the platform, which reduces the moment of inertia and the dynamic load on the platform, as well as the impact on the path. for transportation of piece-packaged, mostly lightweight cargo. Approximate its length is 7 m. The shortened demountable body is designed for the transport of bulk, bulk, mainly heavy cargo. The shortened swap body is about 5 m. In case of oncoming traffic on a closed route in both directions, the proposed platform car with an axle load of 25 tons can carry up to 75 tons of raw materials or fuel in one direction, and in both directions 135-150 tons. while four-axle 80-foot flat cars, when four containers are mounted on them, can carry no more than 75 tons of raw materials and only in one direction, since It is usually not possible to find return freight in the same containers. Thus, the amount of cargo transported in the declared four-axle wagon when transporting cargo in both directions is approximately doubled. Accordingly, the cost of transporting cargo is reduced, and the high economic efficiency of the declared platform car is ensured. A platform car with four two-axle bogies or two three-axle bogies with an axial load of 22.5 tons can carry loads even more.

Description

The utility model relates to railway transport, namely, to wagon-platforms designed for the carriage of various counter-loads in containers, or swap bodies, and on this basis corresponds to the index of MGT B61D 3/00.

Rally platforms transport raw goods in containers in most cases only in one direction, and return in the opposite direction empty. Under the conditions when in Russia the overwhelming majority of cargoes are raw materials and fuel, large empty runs of railcars, platforms and containers are formed.

In this situation, wagons capable of transporting raw materials and fuel in one direction of a closed route, and in the opposite direction another cargo, for example, bulk or piece-packaged, thus eliminating empty runs, are extremely in demand.

The universal platform car is known, model 13-6851 developed by VNIITSTT LLC [Resource https://www.uniwagon.com]. Allows to transport large-capacity containers with a gross weight up to 36 tons. These carriages carry raw goods in one direction only. Back containers are returned empty on a separate platform.

This design is adopted for the prototype 1 car platform.

The known conveyor platform type with four biaxial carriages model 14-6055, type 3935, having a carrying capacity of up to 120 tons, and intended for heavy and long loads [http://rzd-agent.ru].

A platform type transporter with two three-axle bogies of the model 14-T021, also designed for heavy and long loads, is known [http://www.agonta.com/cont.ru/railcars/rc.transporter.ru].

Known 20-foot removable body designed for the transport of various goods [http://vremyaovk.uniwagon.com], having a width of 3.2 m., A length of 6 m, the usable volume is about 55 m ³ . The design and purpose of such removable bodies may be different. This model is adopted for the prototype of the swap body of the declared flat car.

The objective of the claimed utility model is to create a platform car providing dual transportations of any container-capable cargo, including cargo incompatible with each other, alternately in both directions in demountable bodies along closed routes with empty bodies loaded together with the bodies loaded on the same platform.

A platform car, characterized by the fact that it contains bogies, a frame, four swap bodies, two of which are equally shorter than the other two, having the ability to change places with two equally longer ones, and on the frame of the platform there are four pairs of stationary and eight pairs of folding fitting stops, the location of which is sufficient for mounting removable bodies in any of their placement.

The model has the following essential features that ensure the implementation of the stated tasks:

1) On the platform there are four removable bodies with the maximum width for this platform;

2) Two elongated and two shortened demountable bodies are installed on the platform;

3) Removable bodies have a different design, length, capacity and carrying capacity, depending on the transported goods and features of the platform;

4) For mounting, the frame contains four fixed and eight folding fitting stops.

The technical result of utility models is as follows:

- swap bodies, having the maximum width allowed for this platform, can accommodate much more cargo than widespread 60-foot containers, due to which it is sufficient to load only two swap bodies with a load to the full carrying capacity of the platform car, using the remaining loading area to return two empty bodies ;

- due to the different lengths and body designs, the flatcar can alternately transport lightweight cargo in one direction in elongated bodies of maximum capacity, and in the other side - heavy in shortened bodies of maximum carrying capacity.

- a certain arrangement of stationary and folding fittings allows swapping swap bodies, which allows placing loaded loaded bodies always in the center of the platform, and empty bodies at the ends of the platform. This allows to reduce the moment of inertia of the platform and the dynamic load on the carts.

Figure 1 shows the declared flat car with four removable bodies placed on it. Figure 2 shows the installation diagrams of the bodies using fixed and folding fitting stops (pairs of fitting stops are indicated by numbers).

The model (Fig. 1) contains two two-axle bogies 5, two elongated demountable bodies 1, two shortened demountable bodies 2, four lower and four upper fittings in each body, frame 3, on which there are four pairs of stationary and eight pairs of folding fittings four.

In the marketable utility model, the design and dimensions of swap bodies may be different depending on the nature of the goods transported. The width of the body, the maximum width of the frame.

All of them are similar to removable prototype bodies [resource http://vremyaovk.uniwagon.com].

We give examples of the proposed removable bodies.

The elongated demountable body intended for the transportation of piece-packaged, mainly lightweight cargoes, has a length of about 7 m. The internal volume of the body can reach 64 m ³ .

Shortened swap bodies intended for the carriage of bulk, bulk, liquid, mainly heavy cargo, having a length of about 5 meters, and an internal volume of about 44 m ³ .

For the transport of bulk cargo can be used removable body, similar to tank containers, and for the transport of perishable products - thermokuzova, similar to thermal containers.

The bodies on the platform are installed in such a way that either shortened swap bodies are placed in the center of the frame, and elongated bodies - at the ends, or elongated swap bodies - are placed in the middle of the frame, and shortened bodies - at the ends. In the center of the platform can be loaded body, and on the edges of the platform - empty.

Removable body installation:

Four pairs of stationary fitting stops (1, 6, 7, 12) located in the center and along the edges, and eight pairs of folding fitting stops (2-5, 8-11) are used (Fig. 2).

When installing elongated removable bodies in the center, four pairs of folding fittings (2, 3, 10, 11), remote from the center, are transferred to the working position and participate in fastening, and those installed closer to the center are moved to the non-working position.

When installing an elongated body at the ends of the four pairs of folding fitting stops (4, 5, 8, 9), located closer to the center, are transferred to the working position. In the case when the folding fitting stops are not located under the fittings and do not participate in the fastening, they are transferred to the non-working position.

The order of transportation is as follows:

After selecting a pair of oncoming goods to be transported on a given route, the respective carriages of couples of demountable bodies are fixed to the wagon platforms, after which:

- Two containers are loaded with cargo and installed in the middle part of the platform;

- Two empty containers are installed at the ends of the frame;

- The car is sent to the destination point of the route;

- Upon arrival, the loaded containers are removed from the platform and sent for unloading;

- Arrived empty swap bodies are loaded with new cargo and installed in the middle of the car;

- Unloaded swap bodies are installed in the empty state at the ends of the car;

- The car as part of the block train is sent to the starting point of the route.

The economic efficiency of the claimed utility model is due to the fact that, in case of oncoming traffic on a closed route in both directions, the proposed platform car with an axle load of 25 tons can transport up to 75 tons of raw materials or fuel in one direction, and in the opposite direction approximately 60 tons of piece cargo, While 80-foot carriages, when four containers are mounted on them, can transport no more than 75 tons of raw materials on average, and only in one direction, since It is usually not possible to find return freight in the same containers. Thus, the amount of cargo transported in the stated 80-foot car platform, taking into account the load in both directions, is approximately doubled. Accordingly, the cost of transporting cargo is reduced, and the high economic efficiency of the declared flatcar is ensured.

The platform car with four two-axle bogies with an axle load of 22.5 tons has an even greater carrying capacity and allows 120 tons to be transported in one direction, and 200-240 tons in both directions.

A platform car with two three-axle bogies with an axial load of 22.5 tons has a carrying capacity of 95 tons and allows 95 tons to be transported in one direction, and 170-190 tons on both sides.
