[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] The cargo compartment of the railway freight car comprises side walls arranged on the left and right sides of the cargo compartment and end walls arranged on the front and rear ends of the cargo compartment, and the side wall straight rails 3 are arranged on the top ends of the side walls.

[0023] like Figure 1 As shown, this embodiment provides an independent end rail structure, including a transition rail 1 and an end wall straight rail 2, the transition rail 1 is used to connect the end wall straight rail 2 and the side wall straight rail 3, one end of the transition rail 1 is fixedly connected to the end wall straight rail 2 by welding, and the other end of the transition rail 1 is used to be plugged into the side wall straight rail 3 of the cargo compartment, a first mounting seat 4 is arranged on the transition rail 1, and the first mounting seat 4 is used to be detachably connected to the end wall of the cargo compartment by bolts, a second mounting seat 5 is arranged on the end wall straight rail 2, the second mounting seat 5 is welded to the side of the end wall straight rail 2 close to the end wall, and the second mounting seat 5 is used to be detachably connected to the end wall of the cargo compartment by bolts.

[0024] like Figure 2 As shown, the transition rail 1 is fan-shaped, and the transition rail 1 includes a circular arc track 6 and two fan-shaped plates 7. The structures of the two fan-shaped plates 7 are exactly the same and are arranged in parallel. The arc outer edges of the two fan-shaped plates 7 are connected to the inner wall of the circular arc track 6 by welding to form a whole. A plurality of mounting holes 8 are provided near the center of the fan-shaped plate 7, and the first mounting seat 4 is detachably fixedly connected to the fan-shaped plate 7 by bolts passing through the mounting holes 8.

[0025] An insert block 9 is welded between the two sector plates 7. The insert block 9 is U-shaped, with its opening facing the sector plate 7, and one end of the insert block 9 away from the opening protrudes out of the sector plate 7. Figure 3 As shown, a socket 10 is provided at one end of the side wall straight rail 3 near the transition rail 1, and the plug block 9 is inserted into the socket 10 of the side wall straight rail 3, so that the upper end surface of the side wall straight rail 3 and the outer wall of the arc track 6 are smoothly transitioned and connected. In this embodiment, the plug block 9 and the socket 10 are interference fit to ensure the stability of the track operation.

[0026] In this embodiment, the side wall straight rail 3 and the side wall of the cargo compartment are an integrated structure, that is, when the side wall is produced, the top of the side wall is processed into a track structure, and there is no need to process the side wall straight rail 3. On the one hand, it is beneficial to reduce the overall weight of the vehicle. On the other hand, there is no need to install the side wall straight rail 3, which reduces the installation process.
