DETAILED DESCRIPTION First embodiment [0017]As shown in Figures 4 to 6, a rail wagon according to a first embodiment of the present application includes a car body, and the car body includes at least two side plates 1 arranged face to face, a top chord 2 is arranged at an outer side of a top of each side plate 1, and multiple posts 3 are arranged at both side plates 1. The post 3 has a U-shaped cross section, and an opening side fixed on the side plate 1. The side plate 1 includes an upper side plate 11 and a lower side plate 12, and the upper side plate 11 has a bottom portion fixedly connected to a top portion of the lower side plate 12 and a top portion inclined toward an inside of the car body. The post 3 includes an inner post 31 and an outer post 32, and the outer post has an opening side 32a fixed on an outer side of the upper side plate, and the inner post has an opening side fixed on an inner side of the lower side plate. The inner post 31 includes an upper post 311 and a lower post 312, the upper post 311 has a bottom portion fixedly connected to a top portion of the lower post 312, and an opening side 311a matching the opening side 32a of the outer post. [0018] In a circumstance that the wagon has a fixed gabarite, the rail wagon according to the present application employs the post having an internal and external combination structure, that the post has one part arranged inside the car body and the other part arranged outside the car body, which may effectively increase the volume of the wagon and improve the strength of the post. 5182595 1 (GHMatters) P96431.AU 7/03/14 - 5 [0019] In one solution of the first embodiment, referring to Fig. 6, the inner post 31 and the outer post 32 are both formed by a curved plate. The post made of an integral curved plate has no welding seam, thus is difficult to be deformed and has a higher overall strength compared to the post of the welding structure. Second embodiment [0020]As shown in Figures 5 and 7, as another implementation manner of the first embodiment, the inner post 31 and the outer post 32 each includes a bottom surface and two side surfaces surrounding two sides of the bottom surface respectively. Two side surfaces 10 of the outer post are both of an inverted triangular shape, and two side surfaces 20 of the upper post are both of a regular triangular shape. Edges, connected to the outer side of the upper side plate, of the two side surfaces 10 of the outer post matches with edges, connected to the inner side of the upper side plate, of the two side surfaces 20 of the upper post. [0021] In this embodiment, the two side surfaces 10 of the outer post and the two side surfaces 20 of the upper post for supporting the upper side plate 11 are each of a triangular shape, since triangle has a greater stability, the post having the above structure has a higher strength and a greater stability, and since the main part of the post is the inner post, the volume of the wagon won't be affected, thereby ensuring not only the volume of the carriage but also the strength and stability of the post. [0022] In a preferable solution of the second embodiment, for further enhancing the strength of the post in a height direction of the car body, the side surfaces of the inner 5182595 1 (GHMatters) P96431.AU 7/03/14 - 6 post and the side surfaces of the outer post are combined to form side surfaces of the post. The side surface of the post is of a trapezoid shape, and a top edge of the trapezoid has a length shorter than that of a bottom edge of the trapezoid. [0023]As a preferable technical solution for all the above described embodiments, a bottom of the lower post is connected to a bottom surface of the car body via a surrounding plate 4. The surrounding plate 4 is of a concaved arc shape and is configured to prevent bulk cargos, such as ores, from being retained at the bottom of the post, thereby reducing the stress at the weld seam between the inner post and the chassis of the car body and increasing the fatigue life of the weld seam. [0024]It should be noted that, the above embodiments are only intended for describing the technical solutions of the present application, and should not be interpreted as limitation to the present application. Although the present application is described in detail in conjunction with the above embodiments, it should be understood that, for those skilled in the art, modifications may be made to the technical solutions of the above embodiments, or equivalent substitutions may be made to part or all of the technical features in the technical solutions; and these modifications and substitutions also fall into the protection scope of the present application defined by the claims.
