[0002] With the acceleration of economic globalization and the continuous growth of international trade, the container transportation industry has flourished worldwide, providing a broad space for the development of railway container transportation in various countries. As an advanced mode of transportation, container transportation has become the main mode of modern logistics and multimodal transportation with its significant advantages such as high transportation efficiency, low transportation cost, convenient intermodal transportation, less cargo damage, and door-to-door transportation.

[0003] Compared with road transport, rail container transport has multiple advantages such as large transport volume, long transport distance, low cost and all-weather operation, so it has been widely adopted around the world. However, in the actual operation of rail container transport, how to improve transportation efficiency and reduce operating costs, especially in improving the carrying capacity of rail container cars, is still an important challenge facing the industry.

[0004] At present, my country's railway container transportation mainly uses container cars or shared flat cars as transportation tools. Each of these cars can usually transport one 40-foot container or two 20-foot containers.

[0059] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0062] Relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0063] In an embodiment of the present application, a train includes several railway container cars, and each railway container car is connected by a coupler and a buffer device; each railway container car specifically includes a car body, a coupler, a buffer device and a bogie, etc. The car body refers to a steel structure used to carry and place containers.

[0065] like Figure 1-Figure 4As shown, the car body 1000 of the railway container car of the utility model comprises a middle beam assembly 1 and an end beam assembly, wherein the middle beam assembly 1 extends along the length direction of the car body 1000, and the end beam assembly extends along the width direction of the car body 1000 and is fixedly connected to the front end and the rear end of the middle beam assembly 1, and the front side and the rear side of the middle beam assembly 1 are also connected to the coupler 101, and the coupler 101 passes through the end beam assembly to the outside of the end beam assembly; specifically, the end beam assembly comprises two end beam structures 200, one end beam structure 200 is connected to the middle beam assembly 1, and the other end beam structure 200 is connected to the middle beam assembly 1. At the front end of the beam assembly 1, another end beam structure 200 is connected to the rear end of the middle beam assembly 1. Each end beam structure 200 includes a connected end beam cover plate 21 and an end beam end plate 22. The end beam cover plate 21 is horizontally arranged, and the end beam end plate 22 is vertically arranged to the end beam cover plate 21. The end beam cover plate 21 and the end beam end plate 22 are an integrated structure; that is, the end beam structure 200 is formed by bending a whole piece of steel plate. This method can increase the bearing capacity of the end beam structure 200. Its manufacturing method is simple and has good processability. In the process of connecting each end beam structure 200 with the middle beam assembly 1, the end beam cover plate 21 is covered on the upper surface of the middle beam assembly 1 and riveted to the middle beam assembly 1. The front end face and the rear end face of the middle beam assembly 1 are against the end beam end plate 22 on the corresponding side and riveted to the end beam end plate 22 on the corresponding side.

[0066] The vehicle body 1000 further includes an end lock support structure 300 , and the end lock support structure 300 is used to set a locking device 400 , and the locking device 400 is used to limit the container 100 . The end lock support structure 300 specifically includes an end lock support plate 31 and a reinforcement structure 32. The end lock support plate 31 is horizontally arranged and is located in the same plane as the end beam cover plate 21. The end lock support plate 31 is connected to the side of the end beam end plate 22 opposite to the end beam cover plate 21. The end lock support plate 31 is vertically connected to the side of the end beam end plate 22 opposite to the end beam cover plate 21. For the end beam structure 200 located on the front side of the vehicle body 1000, the end lock support plate 31 is connected to the front side of the end beam end plate 22, and the rear side of the end beam end plate 22 is riveted to the front side of the middle beam component 1. For the end beam structure 200 located on the rear side of the vehicle body 1000, the end lock support plate 31 is connected to the rear side of the end beam end plate 22, and the front side of the end beam end plate 22 is riveted to the middle beam component 1. The rear end of the beam assembly 1 is riveted; the upper surface of the end lock support plate 31 is fixedly connected with a locking device 400, and the lower surface thereof is connected to the outer wall surface of the end beam end plate 22 through a reinforcing structure 32 (the outer wall surface of the end beam end plate 22 refers to the wall surface of the end beam end plate 22 away from the side of the middle beam assembly 1. For the end beam end plate 22 located at the front end of the middle beam assembly 1, the outer wall surface of the end beam end plate 22 refers to its front wall surface; for the end beam end plate 22 located at the rear end of the middle beam assembly 1, the outer wall surface of the end beam end plate 22 refers to its rear wall surface). The reinforcing structure 32 is, for example, a plurality of triangular reinforcing ribs arranged in parallel, and of course it can also be reinforcing ribs of other structures, so as to improve the connection strength between the end lock support structure 300 and the end beam end plate 22.

[0067] Through the arrangement in this embodiment, the end lock support plate 31 is connected to the side of the end beam end plate 22 away from the middle beam assembly 1, that is, the end lock support plate 31 extends to the outside of the end beam structure 200, which can reduce the minimum change length of the railway container car, thereby increasing the number of car body 1000 groups within the effective station line length, and improving the overall capacity of the train to transport containers 100. The specific reason is that in the length direction of the car body 1000, the space defined between the locking device 400 located at the front side and the locking device 400 located at the rear side is the accommodating space for the container 100, for example, one 40-foot container 100 or two 20-foot containers 100 can be accommodated in the accommodating space; by arranging the locking device 400 on the outside of the end beam assembly, the container 100 can occupy some space on the outside of the end beam assembly in the length direction, so that the size of the middle beam assembly 1 can be shortened accordingly, thereby reducing the minimum change length of the railway container car. The minimum change length of a conventional railway container car is 1.2. By adopting the solution of this application, the minimum change length of the railway container car can be reduced to 1.1 or less (the number of car bodies in a conventional train is 58, and the solution of the present application is adopted, the number of car bodies in a train is 61); wherein, the minimum conversion length of a railway container car refers to the ratio of the minimum vehicle length L1 of the minimum standard container 100 (20-foot or 40-foot container 100) loaded thereon to the converted standard length, that is, the ratio of the length between the connecting line a of the coupler 101 located at the front side of the car body 1000 and the connecting line a' of the coupler 101 located at the rear side of the car body 1000 to the converted standard length, and the converted standard length is specified as 11m; the two couplers 101 are connected to the middle beam component 1, and the shortening of the length of the middle beam component 1 can shorten the distance between the two couplers 101; contrast Figure 1 and Figure 2 For comparison, Figure 1 It is not the prior art. Figure 1 It is shown that the end lock support structure 300' is arranged on the end beam cover plate of the end beam structure 200'; Figure 2 The technical solution shown in this embodiment is Figure 2 In the embodiment, the end lock support structure 300 is not arranged on the end beam cover plate 21, but is arranged outside the end beam cover plate 21. Figure 1 In the embodiment, the minimum length L1' of the vehicle is the sum of the length L2' of the container 100' and the distance L3' between the end lock support structure 300' and the connection line a or a' of the coupler 101' on the corresponding side. Figure 2 By adopting the method of the present application, the minimum length L1 of the vehicle becomes smaller.

[0068] In this embodiment, see Figure 5-Figure 8The main part of the center beam component 1 is roughly in a "J" shape, and has a center beam upper cover plate 11 connected to the cross beam component and two center beam vertical plates 12 perpendicular to the center beam upper cover plate 11 and arranged opposite to each other along the width direction of the vehicle body 1000. The end faces of the center beam upper cover plate 11 and the center beam vertical plates 12 in the length direction serve as the front end face and the rear end face of the center beam component 1; a center beam connecting plate 13 is welded to the front end face of the center beam component 1, and the edge 132 of the center beam connecting plate 13 extends to the outside of the center beam component 1 and is riveted to the end beam end plate 22. A through hole 131 is provided in the middle of the connecting plate 13, and the through hole 131 is connected to the interior of the center beam assembly 1; by providing the center beam connecting plate 13, the end of the center beam assembly 1 can be riveted to the end beam end plate 22 on the corresponding side, thereby replacing the traditional welding connection process between the center beam assembly 1 and the end beam assembly, reducing the need for collecting welding smoke; at the same time, although the center beam connecting plate 13 and the center beam assembly 1 are welded, since the center beam connecting plate 13 is located at the end of the center beam assembly 1, even if a welding connection method is adopted, it is also convenient to collect welding smoke in a centralized manner.

[0069] In a specific implementation, Figure 1-Figure 8 as well as Fig. 9 and Fig.10 As shown, Fig. 9 is an assembly cross-sectional view of the end beam structure 200 and the middle beam structure 1; Fig.10It is a schematic diagram of the rear follower plate structure 5; the car body 1000 also includes the rear follower plate structure 5, which is used to contact the traction buffer device of the car body 1000 (the traction buffer device of the car body 1000 includes a coupler 101 and a buffer, and the coupler 101 contacts the rear follower plate structure 5 through the buffer, thereby transmitting stress); the rear follower plate structure 5 and the upper center plate 141 are fixedly connected to the middle beam component 1 through a fastening device. Specifically, the lower edges of the two center beam uprights 12 of the center beam assembly 1 are turned outward to form a center beam flange 121 (turning outward means turning toward the side away from the center line of the center beam assembly 1 in the length direction, and the center line of the center beam assembly 1 in the length direction extends along the length direction of the vehicle body 1000 and passes through the center of the center beam assembly 1, that is, the lower edges 132 of the two center beam uprights 12 are turned in the direction away from each other); the center beam flanges 121 of the two center beam uprights 12 extend a certain distance in the horizontal direction away from each other; the center beam assembly 1 also includes a center beam lower cover plate 14, which is arranged parallel to the center beam upper cover plate 11; the center beam lower cover plate 14 is against the corresponding center beam flange 121 and is riveted to the center beam flange 121. This can also replace the traditional welding method without collecting welding smoke. The lower surface of the center beam lower cover plate 14 is provided with an upper core plate 141, and the upper surface of the center beam lower cover plate 14 is provided with a rear follower plate structure 5; during the installation process, the center beam lower cover plate 14, the upper core plate 141 and the rear follower plate structure 5 are riveted together. The rear follower plate structure 5 is located between the two center beam upright plates 12 and is riveted to the center beam upright plates 12 on the corresponding side. In this way, the rear follower plate structure 5 is in contact with the vehicle body 1000 traction buffer device on the one hand; on the other hand, it is riveted to the core plate, thereby integrating the function of the core plate seat, thereby replacing the traditional core plate seat with the rear follower plate structure 5, reducing the number of components in the center beam component 1 (the traditional center beam component 1 is provided with the rear follower plate structure 5 and the core plate seat, which are spaced apart in the length direction, and the space of the center beam component 1 in the length direction is occupied), releasing the space in the length direction of the center beam component 1, and providing feasibility for shortening the length of the center beam component 1.

[0070] The specific form of the rear follower plate structure 5 is schematically illustrated below. The rear follower plate structure 5 includes a lower end plate 51 and an upper end plate 52. The lower end plate 51 and the upper end plate 52 are arranged in parallel in the height direction. The lower end plate 51 is riveted to the middle beam lower cover plate 14 of the middle beam component 1, and the upper end plate 52 is abutted against the middle beam upper cover plate 11 of the middle beam component 1, thereby transmitting the longitudinal load; two side plates 53 are connected between the lower end plate 51 and the upper end plate 52, and the two side plates 53 are arranged in parallel along the width direction of the vehicle body 1000; the two side plates 53 are riveted to the middle beam vertical plate 12 of the middle beam component 1 located on the corresponding side, thereby transmitting the load in the length direction of the vehicle body 1000; the rear follower plate structure 5 can be processed by casting, or it can be processed by welding steel plates.

[0071] Optionally, since the rear follower plate structure 5 in the present application integrates the functions of the core plate seat and the rear follower plate seat, therefore, in the present embodiment, the part where the side plate 53 is riveted to the center beam vertical plate 12 is arranged accordingly; the side plate 53 is divided into a first area 53a and a second area 53b, the first area 53a is closer to the buffer than the second area 53b, that is, in the length direction of the vehicle, the first area 53a is located between the buffer and the second area 53b, and the second area 53b is closer to the side where the upper core plate 141 is located than the first area 53a; the first area 53a and the second area 53b are both riveted to the center beam vertical plate 12 to form a plurality of riveted parts, and the size of the adjacent riveted parts located in the first area 53a in the length direction of the vehicle body 1000 is smaller than the adjacent riveted parts located in the second area 53b.
