Description

The claimed utility model relates to railway transport and concerns the body structure of universal gondola cars.

Known design gondola car [RF Patent for utility model No. 158582 published 03/03/2015], consisting of undercarriages, couplers, braking equipment, a body consisting of a base in the form of a beam frame containing a spinal, two pivot and two end beams connected to the base of the side and end walls, while each end wall consists of a frame and a sheathing and includes an upper part and a lower part, while the upper part is located vertically and is made of a flat shape, and the lower part is located obliquely and connects the upper part to the end beam, moreover, the upper part of the end wall is located at a distance of 100 to 300 mm, measured horizontally from the sheathing of the upper part of the end wall to the middle part of the end surface of the end beam at the location of the impact socket.

The disadvantage of this design is the execution of the connection of the upper part of the end wall with the middle part of the end surface of the end beam at the installation site of the impact socket in such a way that the upper part of the end wall is located at a distance of 100 to 300 mm, measured horizontally from the sheathing of the upper part of the end wall to the middle part of the end surface of the end beam at the installation site of the impact socket.

The location of these elements significantly reduces the manufacturability of the gondola car body due to the complex design of the end wall of the gondola car body, which requires large labor costs in the manufacture, which together is a very laborious process that increases the production cycle.

The above disadvantages lead to a significant increase in the cost of manufacturing the gondola car body structure.

Also known is the design of a railway freight car [RF Patent for utility model No. 158625 published on January 20, 2016], consisting of a body with a frame, side and end walls, brake equipment, a bogie and an automatic coupler, and the upper part of the end wall is made flat and placed outside the frame , the lower boundary of the extended end wall is connected to the frame by an inclined section, and the outer length of the body is less than the distance between the axes of the gondola car couplers by 550-700 mm.

This utility model was chosen as a prototype.

A significant disadvantage is that the end wall is made flat, that is, frameless, which reduces the strength of the body and leads to fractures of the end wall. During the operation of such a gondola car, the destruction of the end walls will most likely occur and, as a result, the requirement for the safety of the cargo will not be met, which is unacceptable.

At the same time, a significant disadvantage of this utility model is the implementation of a gondola car with a length along the axes of coupling of automatic coupling devices of 13920 mm (13.920 m) in accordance with GOST 26725-97 “Four-axle universal gondola cars for 1520 mm gauge mainline railways. General technical conditions”, under which it is possible to place on the station tracks with a length of 988.32 m of cars in the amount of not more than 71 pcs. Based on the parameters of ^the universal gondola car model 12-132 with a body volume of 88 m 2.930 m, internal height of the body - 2.360 m, internal length of the body -13.920-0.55-0.150⋅2=13.070 m 0.150 m, which may be more, then the volume of the body will be less than the calculated one)). Thus, the body volume will be 2.930⋅2.360⋅13.070=90.38 m ³ , therefore, a train formed from such gondola cars can carry cargo (for example, coal) with a volume of 6417 m ³ . This fact allows us to conclude that it is possible to increase the volume of cargo carried in the train, formed from such gondola cars, while the weight of the train remained unchanged.

In addition, this gondola car has an increased tare weight, which increases the length of the rolled products (profiles) used, such as the center girder, I-beam, side wall upper trim, side wall lower trim, corrugated sheathing, the cost of which is increased due to labor intensity. profile manufacturing.

The task to be solved by the claimed utility model is to create a gondola car design that will provide an increase in the number of gondola cars in the train, thereby increasing the volume of cargo carried in the whole train and reducing the tare weight of the gondola car, with a decrease in the length of the used rolled products, combined with an increase in rigidity and strength of the body, as well as a decrease in labor costs in the manufacture of the gondola car body.

The problem is solved due to the fact that the length of the gondola car body ranges from 11662 mm to 11700 mm, the width of the gondola car body does not exceed 3212 mm, the height of the gondola car from the level of the rail head does not exceed 3824 mm, the height from the level of the rail head to the lower horizontal longitudinal profile of the frame the side wall ranges from 1340 mm to 1380 mm.

The essence of the proposed design lies in the fact that a railway gondola car includes bogies, automatic couplers, braking equipment and a body containing a frame with covers in the floor and with a composite spinal beam consisting of upper and lower sections, side and end walls are installed on the frame, consisting from a frame, including horizontal longitudinal and vertical profiles, and from a sheathing located on the inside of the body, while each end wall has several sections, and the upper section is extended beyond the frame towards the coupler and is made of a flat shape, while the length of the gondola car body ranges from 11662 mm to 11700 mm, the width of the gondola car body does not exceed 3212 mm, the height of the gondola car from the level of the rail head does not exceed 3824 mm, the height from the level of the rail head to the lower horizontal longitudinal profile of the side wall frame ranges from 1340 mm to 1380 mm.

The ratio of the height of the lower section of the main beam to the height of the upper section of the main beam is more than 2.389.

The length of the gondola car along the axes of coupling of automatic couplers is 12210 mm.

The frame length ranges from 10985 mm to 10995 mm.

The gondola base is 6940 mm.

Equipped with bogies with an axle load of 25 tons per axle.

The floor of the gondola car body includes twelve manhole covers.

In the lower part of the body, on the side of each end wall, an end sill is installed, connecting the end wall sheathing to the frame.

Railway gondola car, includes bogies (1), automatic couplers (2), brake equipment (3) and a body (4). The body (4) contains a frame (5) with covers (6) in the floor and with a composite center beam (7). Composite main beam (7) consists of upper (7.2) and lower (7.1) sections. Side (8) and end (9) walls are installed on the frame (5), consisting of a frame (10), including horizontal longitudinal (11) and vertical (12) profiles, and from a sheathing (13) located on the inside of the body ( 4). Each end (9) wall has several sections. The upper section (9.1) of the end wall (9) is extended beyond the frame (5) towards the coupler (2) and is made of a flat shape. The length (L) of the body (4) of the gondola car ranges from 11662 mm to 11700 mm, the width of the body (B) of the gondola car does not exceed 3212 mm. The height of the gondola car (H) from the level of the rail head (14) does not exceed 3824 mm. The height (h) from the level of the rail head (14) to the lower horizontal longitudinal profile (15) of the frame (10) of the side (8) wall is in the range from 1340 mm to 1380 mm.

The ratio of the height (b) of the lower (7.1) section of the main beam (7) to the height (a) of the upper (7.2) section of the main beam (7) is more than 2.389.

The length (L1) of the gondola car along the axes of coupling of automatic couplers (2) is 12210 mm.

The length (L2) of the frame (5) ranges from 10985 mm to 10995 mm.

The base (B) of the gondola car is 6940 mm.

The gondola car is equipped with bogies (1) with an axle load of 25 tons per axle.

The floor of the body (4) of the gondola car includes twelve covers (6) of hatches.

In the lower part of the body (4), on the side of each end (9) wall, there is an end sill (16) connecting the skin (13) of the end (9) wall with the frame (5).

The technical result of the claimed utility model is that the length of the gondola car body ranges from 11662 mm to 11700 mm, the width of the gondola car body does not exceed 3212 mm, the height of the gondola car from the level of the rail head does not exceed 3824 mm, the height from the level of the rail head to the lower horizontal longitudinal side wall frame profile ranges from 1340 mm to 1380 mm, which allows to increase the volume of transported cargo (for example, coal) in one train, located on tracks 988.32 m long, by 3.2%.

This indicator was obtained as follows:

- taking into account that the outer length of the body (L) ranges from 11662 mm to 11700 mm, and the thickness (S1) which includes the thickness of the upper trim of the end wall and the displacement of reinforcing pads in the corners of the top trim of the side and end walls beyond the upper trim of the end wall , is 174 mm on each side, then the length (L3) of the body is calculated as follows:

min: 11662 mm - (174 mm + 174 mm) = 11662 mm - 348 mm = 11314 mm (11.314 m).

max: 11700 mm - (174 mm+174 mm) = 11700 mm - 348 mm = 11352 mm (11.352 m).

- taking into account that the outer width (B) of the gondola car body does not exceed 3212 mm, and the thickness (S2) of the upper trim of the side wall is 124 mm on each side, the width (B1) of the body is calculated as follows:

3212 mm - (124 mm + 124 mm) = 3212 mm - 248 mm = 2964 mm (2.964 m).

- in this case, the internal height of the body (A) is the difference (H-h):

min: 3824 mm - 1340 mm = 2484 mm (2.484 m).

max: 3824 mm - 1380 mm = 2444 mm (2.444 m).

- body volume is calculated as the product of length, width and height:

11.314 m × 2.964 m × 2.484 m \u003d 83.30 m ³ .

11.314 m × 2.964 m × 2.444 m \u003d 81.96 m ³ .

11.352 m × 2.964 m × 2.484 m \u003d 83.58 m ³ .

11.352 m × 2.964 m × 2.444 m \u003d 82.23 m ³ .

- we find the average body volume (83.30 m ³ + 81.96 m ³ + 83.58 m ³ + 82.23 m ³ ) / 4 = 82.77 m ³ .

- we find the number of gondola cars according to the proposed technical solution in one train, located on tracks 988.32 m long, while the nominal length (L1) of the gondola car along the axes of coupling of automatic couplers is 12210 mm (12.210 m):

988.32/12.210=80.94 gondola cars, therefore it is possible to install 80 gondola cars in one train.

The volume of cargo in one train, formed from such gondola cars, will be 6621.6 m ³ of cargo (82.77 m ³ ⋅80 pol. \u003d 6621.6 m ³ ).

Thus, if we make comparisons with the prototype (6416.98 m ³ ), then it is possible to assert that the proposed utility model (6621.6 m ³ ) increases the volume of cargo carried in one train by 3.2%.

In addition, the use of the proposed length of the body will allow to reduce the length of the applied longitudinal profiles by 1700 mm, and thereby reduce the tare weight and the cost of the gondola car.

The implementation of the ratio of the height of the lower section of the main beam to the height of the upper section of the main beam in such a way that it is more than 2.389 allows you to increase the volume of the body, reduce the center of gravity of the gondola car, and, as a result, improve the dynamic qualities of the car.

This ratio of the heights of the main beam was obtained as follows:

The height (a) of the upper section is max 128.5 mm.

The height (b) of the lower section is min 307 mm.

Ratio (b)/(a) = 307 mm / 128.5 mm = 2.389.

That is, the ratio of the height of the lower section of the main beam to the height of the upper section of the main beam is more than 2.389.

The length of the gondola car along the axes of coupling of automatic couplers with a size of 12210 mm ensures the installation of 80 gondola cars according to the proposed utility model in one train, located on tracks 988.32 m long.

The execution of the frame length in the range from 10985 mm to 10995 mm ensures the length of the gondola car along the axes of coupling of automatic couplers in the amount of 12210 mm.

The execution of the gondola car base, that is, the distance between the two centers of the pivot nodes, in the amount of 6940 mm, ensures the unhindered passage of the gondola car into the radius curves of the railway tracks.

Installation of bogies with an axle load of 25 tons per axle under the gondola car body provides an increase in the gondola car carrying capacity, which in turn increases the train carrying capacity.

The execution of the floor, which includes twelve hatch covers, ensures the use of universal hatch covers, as well as unimpeded unloading of the gondola car through open hatch covers.

The execution in the lower part of the body from the side of each end wall of the end sill, which connects the skin of each end wall with the end beam, allows to increase the strength in the lower part of the gondola car body.

Currently, design documentation has been developed for the declared utility model and comprehensive testing of prototypes is being carried out.
