Description

The invention relates to a railway wagon with a container loading support device.

Err1:Expecting ',' delimiter: line 1 column 250 (char 249)

It is also increasingly desirable to be able to transport freight containers, as used for transporting goods on ships, on such wagons, which would greatly simplify the handling of the goods transported, since there is no need to transfer the goods from the shipping container to the wagon if the container as a whole can be used in the wagon.

The railway flat wagon shown in DE 101 55 696 A1 is suitable for transporting such a container. The flat wagon has a centrifugal device which limits the usable width of the cargo compartment. To support a container, the known wagon has supporting devices extending over the entire height of the sidewall of the flat wagon. This wagon has the disadvantage that although it can carry containers, it cannot easily carry bulk goods, since the flat would not be loaded in terms of weight. For the transport of bulk goods with optimum load wagons, freight transport usually uses wagons with high sidewalls, e.g. the aforementioned Ea-aggons.

The present invention is intended to specify a freight wagon which can be used for the transport of both bulk or unit goods and cargo containers without the need to make changes to the wagon when changing the type of cargo.

This task is solved by a railway carriage as claimed in claim 1.

The freight wagon of the invention shall have at least one floor and at least one side wall. The side walls shall comprise at least one longitudinal wall and at least one transverse wall, the length of which shall be greater than that of the at least one transverse wall, and the length of which shall be essentially perpendicular to the length of at least one transverse wall, and at least some of the side walls shall have supporting devices on the inside of the interior, which shall be at the height of one third of the wall on the upper sides and shall extend from each side into the interior of the space enclosed by the side walls.

The supporting devices allow containers, such as the above-mentioned shipping containers, to be carried safely without slipping and thus endangering the contents. The risk of slipping or moving the container would be present without supporting devices, especially during acceleration and braking operations. In addition, the supporting devices also allow the container to be guided when it is loaded into the wagon and when it is taken out of the wagon.

Unlike the state of the art according to DE 101 55 696 A1, the supporting devices do not extend over the entire height of the side walls of the wagon, but only about the upper third, preferably the upper quarter of the same. This results in a saving in material and weight in the manufacture of the wagon. Surprisingly, it has been found to be completely sufficient to provide the supporting devices over only a small part of the height H of the side walls.

In contrast to the state of the art mentioned above, the railway wagon of the invention does not have any limitation in the cargo space; without any significant weight limitation due to fittings, the wagon of the invention can carry both containers and bulk goods in the usual quantity, i.e. the quantity authorized for the type of wagon.

According to a preferred embodiment of the railway car according to the invention, there are four side walls which enclose an interior space and thus form a closed carriage.

Preferably, the railway wagon of the invention has at least one door in its longitudinal wall, which facilitates loading and unloading of goods not contained in containers, as well as cleaning and waiting of the wagons.

In the practical design of the railway car according to the invention, the supporting devices are preferably composed of a base plate which is attached to the respective side wall in an angle to it and a load limiting plate which is attached to the base plate at an angle which is preferably a right angle, although slight deviations of 90°, e.g. 85° to 95°, are possible.

The base plate of the supporting device, on the other hand, has an optimum thickness of about 8 to 15 mm.

The base plate and/or the load limiting plate are preferably welded together, and a welding connection is preferred for the attachment of the base plate to the side wall of the wagon for stability.

According to a particularly suitable embodiment of the invention, the load limiting plate has a slope on its upper side further away from the floor wall. This means that the load limiting plate is tapered upwards. This results in advantages, especially when loading a container into the wagon according to the invention, as the container is guided so that it can slide safely to the desired position.

In addition to or as an alternative to the design described above, the load limiting plate may also have a slope on its bottom side closer to the floor wall and thus taper towards the floor side, thus providing a particularly good guide during unloading.

For this purpose, the railway wagon of the invention shall have four supporting devices on at least one of the longitudinal walls, the distance between the first supporting device and one end of the longitudinal wall being approximately 35 cm, the distance between the first and second supporting devices being approximately 610 cm, the distance between the second and third supporting devices being approximately 10 cm, and the distance between the third and the fourth supporting devices being approximately 610 cm. In this way, two containers can be safely transported and protected against slippage at the same time. However, a single container of double length may also be used.

In addition to the supporting devices on the longitudinal walls, at least one of the transverse walls may have two supporting devices separated by 249 cm.

The present invention is further explained in relation to the attached drawings, which are a preferred example of the embodiment. Figure 1 shows a railway carriage of the invention in view;Figure 2 shows a longitudinal view of a supporting device for a longitudinal wall; andFigure 3 shows a longitudinal view of a supporting device for a transverse wall.

In the example shown, the railway carriage of the invention has two longitudinal walls 1 and two transverse walls 2 which are arranged in a rectangular pattern, and all the walls 1, 2 are fixed on a floor wall 3 in the usual way at their bottom.

As can be seen, there are four supporting devices 4 on each of the longitudinal walls 1 and two supporting devices 2 on each of the transverse walls 2 and, of course, a different number of supporting devices can be selected as needed.

The supporting devices consist of a base plate 4a, which runs parallel to and adjacent to the side walls, and a load limiting plate 4b, which extends into the interior space enclosed by the side walls.

The height of the supporting structures 4 is only a fraction, in particular about a quarter to a fifth, of the height H of the side walls and is in the upper third of the height of these side walls. In numerical terms, the height of the supporting structures is preferably between 25 and 60 cm, with a range of 30 to 45 cm being considered particularly preferable. The height of the supporting structures of the longitudinal walls may be lower than the height of the supporting structures of the transverse walls.

As can be seen from the illustrations in Figures 2 and 3, the load limiting plates 4b of the supporting devices 4 have the shape of a trapezoid in longitudinal view, i.e. perpendicular to the view in Figure 1, i.e. their upper and lower corners are highly slanted, thus ensuring a safe direction or centering of the containers during loading and unloading of the railway wagon of the invention.

The railway wagon of the invention allows the transport of containers normally used for ship transport as well as bulk cargoes in the usual way without the need for modification of the type of cargo. This allows the wagon to be economically optimal. The supporting devices required for this can be realized with low material consumption due to the invention.
