Railway wagon for transportation of swap bodies, especially containers

Abstract

A railway wagon for transportation of swap bodies, in particular containers, is length-adjustable, consisting of length-adjustable end sections (1) (overhangs) and a length-adjustable middle section (2) for flexible adjustment of wagon length for the purposes of efficient transport by rail. The end (overhang) section (1) of the wagon is designed for the installation of buffers, automatic coupling, for placement of push-pull rods, or buffers for short coupling of wagons, thus enabling creation of double and multi-section wagon length versions (80', 90', 92', 96', 104', and others).

Description

FIELD OF TECHNOLOGY

[0001] The invention relates to a freight railway wagon designed for freight railway and intermodal transport.STATE OF THE ART

[0002] Freight and, in particular, intermodal rail transport is an important and rapidly developing form of freight transport in Europe. This is closely linked to the need to increase both the efficiency and flexibility of transport. Since the design and operational life of containers and swap bodies is approximately half that of a freight wagon, there is a faster replacement of swap bodies in terms of both number and, above all, type. This shortcoming is addressed or compensated for by modularity in design solutions so that freight rail transport can respond flexibly to market demands.

[0003] There are currently several systems at the market that address modularity, the first of which is the Flex Freight System, which focuses more on logistics than on modular rail wagon solutions. Another is the Trans Ant modular complex, which consists of container wagons made of high-strength steel and available in various lengths from 11 to 23 m. Another system is the DBm 2< system, in which the underframe of the wagon has a special design and consists of two overhangs connected by a centre beam of various lengths. Another is the KIRUNA WAGON'S Modular System, which allows production of a basic platform of various lengths, but the supporting structure itself is not part of the basic platform; these are separate superstructures for transporting various types of cargo.NATURE OF TECHNICAL SOLUTION

[0004] The length modularity of railway wagons for transporting swap bodies, especially containers, is solved by a solution defined in the claims, the essence of which is that it allows flexible length adjustment of the wagon in both the end and central (or other) part, which allows the length of the wagon to be adjusted according to the type or length of the swap body being transported. A railway wagon for transporting swap bodies, in particular containers, is lengthened by extending the sliding end part of the overhang, i.e. the extension is performed in the end overhang part (at one or both ends) and / or by extending the sliding central part or by inserting an extension part in the central or other part of the wagon underframe between the end parts (overhangs). The end section of the wagon is designed for the installation of buffers, automatic coupling, push-pull rod, or buffers for short coupling of wagons. In practical terms, this means that the technical solution allows different combinations of lengths to be created from a single wagon length without the need to purchase specially manufactured wagons. For example, it will be possible to create variations in lengths of 45', 52', 80', 90', 92', 96', 104', and others from a wagon with the type designation Sgmmns 40' (40 feet).

[0005] The advantage of this concept in terms of wagon lengths is that it is possible to use the existing positions of container pins for most of the anticipated loading schemes. This also applies to multi-section wagon combinations and articulated wagon designs. The proposed solution uses both fixed and adjustable positions for container elements and other securing mechanisms for placing swap bodies, especially containers.OVERVIEW OF FIGURES IN THE DRAWINGS

[0006] Figure 1 shows a wagon with three different parts for adjusting its length. Figure 2 shows the end part of the wagon with an adjustable overhang. Figure 3a shows a wagon with an extension of the central part of the wagon by extending or inserting one or more parts. Figure 3b shows a wagon with an extendable end section (overhang) designed for buffers or with an extendable end section (overhang) on the side of the articulated connection between wagons. Figure 3c shows a standard wagon without a solution for adjusting its length.EXAMPLES OF EMBODIMENT

[0007] A railway wagon for transportation of swap bodies, in particular containers, such as that shown in Figure 1, the Sgmmns(s) 40' wagon, is prolonged by extending the sliding end section 1 of the overhang, i.e. the prolongation is made in the end (overhang) section (at one or both ends), as shown in Figure 2, and / or by extending the sliding central section 2 or inserting the central section 2 in the middle or another part of the wagon underframe between the end sections 1 (overhangs). The end (overhang) section 1 of the wagon is designed for the installation of buffers, automatic coupling, for placement of a push-pull rod, or buffers for short coupling of wagons, thus making it possible to create double and multi-section wagon length versions (80', 90', 92', 96', 104', and others).INDUSTRIAL APPLICATIONS

[0008] The described solution consists of flexible adjustment of the wagon length according to the current market demand for transportation of containers and swap bodies or other cargo. The solution offers increased modularity and flexibility for the end customer. The solution enables increased transport efficiency, increased competitiveness of rail transport, and reduces costs of purchasing new wagons.
