Description

The utility model relates to railway rolling stock, namely to the design of articulated wagons designed for bulk transportation of goods.

Known articulated hopper car (Russian patent No. 149541, IPC B61D 7/00, publ. 01/10/2015), the closest in technical essence to the claimed device and adopted as a prototype containing a chassis and a body that is mounted on the chassis and which contains at least two consecutive sections for receiving cargo, and the chassis contains at least three trolleys, each section of the body resting on two trolleys, and adjacent sections of the body resting directly or indirectly on a common trolley.

The disadvantages of the known car are:

- low carrying capacity, which does not allow full use of the volume of bodies when transporting goods with high bulk density. Loading and unloading operations of wagons are carried out, as a rule, on racks providing for the simultaneous loading / unloading of several wagons. In this regard, this type of carriage has a typical length along the clutch axes of automatic couplings. To eliminate the need for additional operations to disband and form the composition of the cars during loading / unloading, an articulated car should have a multiple of a typical length along the clutch axes of automatic couplings. Moreover, in connection with the execution of the car in the form of an articulated car, this car will have fewer bogies compared to several four-axle cars combined in the same length. Thus, when using the same type of bogies, the carrying capacity of an articulated car will be lower than the total carrying capacity of several four-axle wagons combined in the same length. This decrease in carrying capacity is permissible when transporting goods with a low bulk density, when transporting them in four-axle wagons, the carrying capacity is not fully used when the body volume is fully used. However, when transporting goods with a high bulk density, the mass of the cargo transported in an articulated wagon will be less than the total mass of the cargo transported in several four-axle wagons combined in the same length. At the same time, the volume of the articulated car bodies will not be fully used.

- asymmetry of the internal volume of the body of the section relative to the vertical plane perpendicular to the longitudinal axis of the car and equidistant from the inner surfaces of the sheathing sheets of the end walls of the body of the section. Known four-axle wagons have, as a rule, the internal volume of the body (limited by the surfaces of the power elements and body sheathing sheets and manhole covers facing the interior of the body), symmetrical with respect to the vertical longitudinal and vertical transverse planes of the car. At the same time, body bunkers with unloading hatches are located in the space between the carriage bogies. In the aforementioned articulated carriage, at least one discharge hopper is provided in the cantilever part of the end section. The location of the hopper in the console part of the section is adopted to increase the uniformity of load distribution on the wagon trolleys. However, with such a body structure of the extreme section, the internal volume of the body of this section is asymmetric with respect to the vertical plane perpendicular to the longitudinal axis of the car and equidistant from the inner surfaces of the sheathing sheets of the end walls of the body. It is worth noting that the well-known wagons are intended for the transportation of a wide range of bulk cargoes. The bulk density of various cargoes differs from each other and lies in a wide range. Accordingly, the volume occupied in the wagon body by various weights with full use of the wagon's carrying capacity (i.e., with the same mass of transported cargo) will also differ and lie in a certain range. In this case, the center of gravity of goods with different bulk density, placed in the body of the extreme section, will be located at different points. The indicated points will be located at some distance from each other in the vertical direction due to the different loading level of the body, as well as in the direction of the longitudinal axis of the car due to the asymmetry of the section body. It is worth noting that due to the invariance of the distance between the extreme and middle carriages of the carriage, the equality of the vertical loads acting on the truck spars from the loaded sections of the carriage will be ensured only in cases when the center of gravity of the cargo is located on a plane perpendicular to the longitudinal axis of the carriage; the position of the indicated plane along the longitudinal axis of the car depends on the design of the car and for each model of the articulated car is strictly defined and unchanged. Thus, due to the asymmetry of the internal volume of the body during transportation of various cargoes (especially with high bulk density), cases of uneven distribution of the vertical load acting on the truck trolleys from the loaded sections of the car are possible. Since the excess of the calculated static axial load of the bogies is not allowed in operation, one of the consequences of the uneven distribution of the specified vertical load is the underutilization of the carriage capacity. In addition, the uneven distribution of this vertical load leads to a deterioration in the dynamic performance of the car.

The technical problem solved by the creation of a utility model is the insufficient carrying capacity of articulated cars.

The technical result, which the utility model aims to achieve, is to increase the carrying capacity of an articulated hopper car.

An articulated hopper car is proposed, consisting of carriage sections arranged in series, containing a body for placing cargo and an unloading hopper for unloading it, and connected to each other by an articulated joint assembly, and containing a common chassis formed by end carts and an intermediate carriage, each the section rests on the extreme biaxial trolley, and the sections of the car in the area of the articulated joint assembly are supported on one intermediate trolley.

The intermediate trolley is a triaxial trolley.

At the same time, the hopper car contains an unloading hopper in each section of the car, located in the space between the extreme and intermediate carts, on which the car section is supported.

An increase in the carrying capacity of an articulated hopper car is achieved through the use of a three-axle carriage and a discharge hopper in each section of the car as a common (intermediate) carriage.

Thus, the use of a triaxial trolley as a common (intermediate) trolley ensures the full utilization of the bearing capacity of all wagon trolleys, each extreme section of which has a body symmetrical about a plane perpendicular to the longitudinal axis of the car.

Also achieved:

a) improving the dynamic qualities of a loaded articulated wagon during the transportation of goods with high density;

b) ensuring the full use of the wagon's carrying capacity when transporting goods of the entire range of bulk densities, including goods with a high density;

c) increasing the economic efficiency of the transportation of goods with high density.

The inventive device is illustrated in the figure, which shows a General view of the car of the articulated type, as an example shows a General view of the hopper car.

The inventive device consists of the following elements:

1 - extreme biaxial carts;

2 - intermediate triaxial trolley;

3 - section of the car;

4 - body;

5 - articulated joint.

The wagon contains the carriage chassis, which is formed by two extreme biaxial trolleys 1 and one intermediate triaxial trolley 2, and also contains two successive sections of the carriage.

In addition, the car contains two sections 3 of the car, each of which has a body 4, designed to accommodate the transported cargo.

Each section 3 of the car is connected to the adjacent section by an articulated joint 5.

Each section 3 of the car with one end rests on the corresponding extreme biaxial trolley 1.

Moreover, a pair of adjacent sections 3 of the car in the area of the joint 5 is supported directly or indirectly on one common triaxial intermediate carriage 2.

Each of these sections 3 of the car is mounted on two bogies, has a body for accommodating cargo and is connected to the neighboring section 3 by an articulated joint 5.

Moreover, each section 3 of the carriage is supported by one extreme biaxial carriage 1, and each pair of adjacent sections 3 of the carriage in the area of the articulated joint 5 is supported directly or indirectly by one common intermediate three-axle carriage 2. In this case, the body 4 of each section 3 of the carriage has parts of at least one discharge hopper with a hatch for unloading the transported cargo from the body 4. In addition, each hopper for unloading the transported cargo from the body 4 of each section 3 of the car is located in the space between the extreme biaxial 1 and ezhutochnoy triaxial two bogies on which rests said carriage section 3.

The body 4 of each section 3 of the car, in a preferred embodiment, has an internal volume (limited by the surfaces of the power elements and / or sheets of the skin of the body 4 and the manhole covers facing the inside of the body 4), while the body is made symmetrical about a plane perpendicular to the longitudinal axis of the car.

The use of bunkers allows you to increase the volume of the body 4 cars and, accordingly, the carrying capacity of the articulated hopper car.

In this case, a reduction in operational, time, material and labor costs is achieved.

These positive effects have a favorable effect on the overall performance of the car.
