Description

Freight wagon on rails.

Technical field

The invention relates to a freight car on rails for bulk loading with a frame with at least 2 individual axes or a bogie, as well as a container that presents the less a lower discharge duct, presenting the container to the minus an additional camera on the bogie, which has a conduit of lower discharge in the bogie area.

State of the art

A freight wagon on rails is known for bulk loading of the type described at the beginning by the document US-PS-5,248,227. In the wagon of goods known from document DE 7344758 U1, the surface of the container floor is formed by juxtaposed cones, which respectively have a lockable hole in the directed tip down and thereby form a lower discharge duct. The conical shape is necessary so that after opening the duct bottom discharge, bulk cargo leave the container completely due to the force of gravity. At the beginning and end of frame is respectively a bogie with wheels. The Bottom discharge ducts of the container are located approximately at the height of the bogies between the front bogie and rear. With this configuration, the space on the bogies is essentially unused, since the walls of the container have to climb starting from both lower discharge ducts directed outward at least with such an inclination angle that guarantees the exit of the bulk cargo.

As for the accommodation of a container in boiler shape in the frame of a freight wagon, the DE 41 32 047 A1 shows a complicated mounting frame composed of two parts limitedly mobile to each other in direction longitudinal, each part being welded to the container In a small contact area.

In addition, wagons in the form of a boiler are known for DE 4037014C2, DE 1605105C3 and utility model G 8705085.4, in which support plates directed towards the boiler up and out of the frame support a boiler cylindrical The support plates are attached to the walls of the boiler only partially. In this way, they can originate easily stress concentrators at the corners of the joints, which can cause cracks and other damage after a prolonged time. This is especially true when the junction between the support plate and the container is welded and the container is made of some resistant material like aluminum.

For the document FR-A-2,634,440 a wagon is known cistern that presents support plates directed towards the tank.

Presentation of the invention, objective, solution, advantages

Given this background, the objective of the invention is to develop a freight wagon on freight lanes to bulk that has an improved capacity utilization, in that the union of the container with the frame is configured of the more stable way.

This goal is achieved with a wagon of goods on rails with the characteristics of the claim 1. The subordinate claims detail advantageous configurations.

The freight wagon on loading rails in bulk it has a frame with at least 2 individual axes or a bogie, preferably with a bogie at each end of the frame. It also has a container for bulk loading, presenting the container at least one bottom discharge duct and at least an additional camera on the bogie / s, which has a conduit Lower discharge in the bogie area.

The configuration according to the invention of the freight wagon according to the invention affects the assembly of the container on the frame. According to this configuration, the frame presents a surrounding substructure, which is attached, preferably welded, to the container. The decisive thing is that the substructure is linked in a closed line with the container, of so that there is nowhere a beginning or an end of the union where stress concentrators could be formed. A union surrounding of this type of substructure with the container gives place, therefore, at a higher maximum permissible load and a life Longer service.

Said substructure is formed by a sheet support, which, starting from the frame direction to the wall of the container, surrounds the container once forming a band closed.

This takes advantage of the freight car on the space over bogies for bulk cargo storage at extend the container in that space through a camera additional. The emptying of this additional chamber is ensured by a lower discharge duct located relative to the axis longitudinal car in the bogie area.

According to a first configuration the lower discharge duct of the additional chamber may be placed above the bogie. Other discharge ducts lower are, on the contrary, typically located to it height than the bogies, in order to maximize the volume of storage. Being the lower discharge duct of the additional camera located higher, it can accommodate slightly less than volume in the additional chamber than in the "normal" cameras. TO Despite this, there is an increase in available space considerable when the space on the Bogies

In addition, the discharge duct can be arranged bottom of the additional chamber so that it passes through the Bogie In this case it ends at approximately the same height that the "normal" lower discharge ducts of the remaining cameras, thus maximizing the volume of the camera additional. For this, it is necessary, if necessary, to modify the bogie structure so as to leave free space for the camera additional and / or its lower discharge duct. In the case of a biaxial bogie the lower discharge duct is typically located Between the two axes.

The dumps bottom of the container of the freight wagon preferably have a conical shape, of way to conduct the bulk cargo contained in the container towards the opening as a funnel. The cones of ducts Adjacent lower discharge are typically in contact with each other. others, so that the entire floor of the container is formed by sloping walls and, as a result, when the ducts of bottom discharge are open the total load is discharged to bulk container.

Brief description of the figure

The invention is described below with the aid of the figure. The only figure shows a side view of the wagon of goods on rails for bulk cargo according to the invention 100.

Best way to realize the invention

The freight car consists of a frame 15 with a container 16 on it. The frame 15 presents in its front and back ends a biaxial bogie 10a and 10b respectively, on which it is driven on rails (not represented).

The container 16 has at its bottom five conical lower discharge ducts 12 whose openings in vertical direction are located approximately at the height of the Bogies 10a, 10b. The exit cones are contiguous and each of they vertically form a conical camera K2, K3, K4, K5 and K6

In freight wagons known, the container 16 has only the aforementioned cameras K2, K3, K4, K5 and K6, which are characterized in that their lower discharge ducts 12 are located in the direction of the two bogies 10a and 10b, seen in the direction of the longitudinal axis of the car. Container length complete is thus considerably limited by the separation of The Bogies In traditional freight wagons the space about the bogies remains essentially unused as consequence of the inclination angle of the exit cones, especially in the case of exit cones K2 and K6, it should not be too flat for the bulk cargo to slide to the exterior and that the sheet of the outer cones K2 and K6 has to go through the bogie 10a and 10b.

To maximize the capacity of the freight car, prolongs the container 16 according to the invention by two Additional cameras K1 and K7 at both ends. These cameras Additional K1 and K7 have the same as "normal" K2 cameras - K6 a lower conical discharge duct 11a and 11b to be able to completely unload bulk cargo. Unlike cones "normal" the lower discharge ducts 11a and 11b are found horizontally in the area of bogies 10a and 10b and in vertical located on each of them.

Thanks to the additional cameras K1 and K7 it you can also take advantage of the space on the bogies and with it increase the capacity of container 16. At the same time ensures that container 16 maintains the minimum separation D of the bumper of the freight wagon 100 prescribed in the codes relevant. Except because of this prescribed separation, it is not Wastes no cargo space.

Another advantage of the freight wagon 100 depicted in the figure resides in the form of assembly of the container 16 on the frame 15. This assembly takes place on a substructure in the form of support plates 13 which are from the frame 15 upwards towards the container 16. The support plates 13 form a closed band around the container 16. The container 16 and the support plates 13 are soldiers in your contact line. Welding line 14 like this generated is continuous and closed, unlike that of constructions traditional, in which support plates only support the container walls in some areas. This prevents the ends of the welding line appear concentrators of tensions Wagons with a boiler-shaped container design conventional are, especially those that are manufactured in aluminum, very sensitive to the appearance of fissures in the substructure under continuous load due to this type of stress concentrators. On the contrary, the assembly proposed surrounding and welding of the container to the sheets of support are considerably more robust and with a lifetime of Longer service
