Abstract
Description
Technical Field
[0001] This utility model relates to the side wall composition of a railway container transport vehicle and the railway container transport vehicle itself. Background Technology
[0002] Container shipping is a modern mode of transportation that uses containers as the unit of transport for goods. It is characterized by "safety, efficiency, convenience, greenness, and economy".
[0003] Currently, the main container types used in railway freight are 20-foot and 40-foot general-purpose containers. However, the number of 48-foot containers is gradually increasing. Existing vehicles transporting 48-foot containers have the problem that they cannot be directly loaded onto the lower level of the vehicle; instead, one 40-foot container or two 20-foot containers must first be loaded onto the lower level, and it is impossible to load 48-foot containers on two levels simultaneously.
[0004] The sidewalls are an important component of the railway container transport vehicle body.
[0005] Therefore, there is a need to provide an improved sidewall composition to accommodate extended railway container transport vehicles for transporting large double-stack containers. Utility Model Content
[0006] One objective of this invention is to provide a sidewall assembly for a railway container transport vehicle, applicable to extended railway container transport vehicles for transporting large double-stack containers. Another objective of this invention is to provide a railway container transport vehicle.
[0007] The present invention achieves the above objectives by adopting the following technical solution.
[0008] On the one hand, this utility model provides a side wall assembly for a railway container transport vehicle, which includes a middle side plate, a lower side beam assembly, a first column, and a second column;
[0009] The length direction of the middle side plate is the same as that of the railway container transport vehicle; the middle side plate is flat and vertically arranged, and has multiple weight-reducing holes.
[0010] The lower side beam comprises a vertical section, a horizontal section, and a U-shaped section, all three of which share the same length direction as the railway container car. The vertical section is flat and vertically positioned. The horizontal section is flat and horizontally positioned. One side of the horizontal section is connected to the bottom of the vertical section, forming an angle greater than 85° and less than 95° between them. The U-shaped section has a U-shaped cross-section and is located below the horizontal section. The top opening of the U-shaped section faces the horizontal section and is closed by the horizontal section. The center plane of the U-shaped section, perpendicular to its width direction, is perpendicular to the horizontal section.
[0011] The top of the vertical section is connected to the bottom of the middle side plate;
[0012] Both the first and second columns are multiple, and are arranged vertically and at intervals; a portion of the first columns are located near the end of the middle side plate, and another portion of the first columns are located near the middle of the middle side plate; at least a portion of the first columns are connected to the outer surface of the middle side plate, the outer surface of the vertical portion, and the outer surface of the U-shaped portion near the vertical portion, respectively; the second columns are connected to the outer surface of the middle side plate and the outer surface of the vertical portion, respectively; all these outer surfaces are far from the center plane of the railway container transport vehicle perpendicular to the width direction;
[0013] The width of the second column is smaller than that of the first column. This helps to reduce the weight while ensuring the structural stability of the side walls, making it suitable for loading and transporting large double-stacked containers on extended railway container wagons.
[0014] In this invention, weight-reducing holes are added to the middle side plate. These holes can be elliptical and are positioned closer to the top of the middle side plate. This helps to reduce the weight while ensuring structural stability.
[0015] Compared with the existing technology of lower side beam structure, the lower side beam structure of this utility model is more stable and has less self-weight.
[0016] In this invention, the length of the first column is greater than the length of the second column. At least a portion of the first column is connected to the outer surface of the middle side plate, the outer surface of the vertical portion, and the outer surface of the U-shaped portion near the vertical portion, thereby enabling the base of the first column to adopt an inward-curving structure, which helps to reduce wind resistance during operation.
[0017] According to the sidewall composition of the railway container transport vehicle described in this utility model, preferably, the bottom of the vertical part and one side of the horizontal part are connected by an arc-shaped structure, the arc of which is greater than 85° and less than 95°. This results in an included angle between the horizontal and vertical parts being greater than 85° and less than 95°. That is, the connecting section between the vertical and horizontal parts is an arc-shaped plate. The arc can be, for example, 90°.
[0018] According to the sidewall composition of the railway container transport vehicle described in this utility model, preferably, the outer contour of the vertical part is an isosceles trapezoid, which has an upper base, a lower base, a first hypotenuse, and a second hypotenuse. The length of the upper base is greater than the length of the lower base; the length of the lower base is the same as the length of the horizontal part, and the lower base is connected to the horizontal part through the arc-shaped structure. This structure facilitates connection with the end side plates and reduces weight.
[0019] According to the sidewall composition of the railway container transport vehicle of this utility model, preferably, the included angle between the first inclined side and the upper bottom side is greater than 10° and less than 50°. More preferably, this included angle is greater than 10° and less than 45°. This structure facilitates connection with the end side plates and reduces weight. The included angle between the second inclined side and the upper bottom side is greater than 10° and less than 50°. More preferably, this included angle is greater than 10° and less than 45°.
[0020] According to the sidewall composition of the railway container transport vehicle described in this utility model, preferably, the first uprights are configured as three or more, with two of them located near both ends of the middle side plate and one near the middle of the middle side plate; the second uprights are configured as eight or more, with the weight-reducing holes provided between adjacent second uprights; the weight-reducing holes are elliptical holes, and the length direction of the weight-reducing holes is the same as the length direction of the middle side plate. This helps to reduce the self-weight while maintaining the structural stability of the sidewall composition.
[0021] According to the side wall composition of the railway container transport vehicle described in this utility model, preferably, it also includes an upper side beam, the length direction of which is the same as the length direction of the railway container transport vehicle; the upper side beam is configured as a rectangular tube and is vertically arranged; the bottom of the upper side beam is connected to the top of the middle side plate; the length of the upper side beam is greater than the length of the middle side plate. The height of the transverse section of existing upper side beams is no more than twice the width of its transverse section. Compared with existing upper side beams, the upper side beam of this utility model is higher but narrower, indicating a larger vertical bending section modulus and stronger resistance to vertical deformation.
[0022] In this invention, the center plane of the upper side beam perpendicular to its length direction is coplanar with the center plane of the middle side plate perpendicular to its length direction. The thickness of the first column is less than the thickness of the upper side beam. The thickness of the second column is less than the thickness of the first column. The upper side beam is basically rectangular tubular.
[0023] According to the side wall composition of the railway container transport vehicle described in this utility model, preferably, the height of the transverse section of the upper side beam is greater than twice the width of its transverse section. This is beneficial for improving the vertical bending modulus and enhancing the resistance to vertical deformation.
[0024] Preferably, the sidewall composition of the railway container transport vehicle according to this utility model further includes end side plates, which include a first end side plate and a second end side plate, respectively symmetrically arranged at both ends of the middle side plate; the top of the end side plate is connected to the bottom of the upper side beam, and the bottom of the end side plate is connected to the vertical part. The specific shape and structure of the end side plate can refer to the prior art.
[0025] According to the side wall composition of the railway container transport vehicle described in this utility model, preferably, the upper part of the end side plate is provided with end side plate weight reduction holes.
[0026] On the other hand, this utility model also provides a railway container transport vehicle, including multiple carriages, characterized in that at least one carriage includes two sets of side walls as described above, and the two sets of side walls are symmetrically arranged with the central plane of the railway container transport vehicle perpendicular to the width direction as the symmetrical surface.
[0027] The side wall assembly of this utility model is an improvement on the existing structure. By optimizing the structure of the lower side beam, the setting of the first and second columns, and the structure of the upper side beam, and by adding weight-reducing holes in the middle side plate, the load-bearing capacity of the vehicle body is ensured and the self-weight is reduced. In addition, the thickness of the sheet metal of parts at different positions is reasonably matched (the thickness of the end side plate is greater than that of the middle side plate) to ensure the load-bearing capacity of the vehicle body.

[0038] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.
[0039] Example 1

Figure 2 This is a schematic diagram of the middle side plate and the end side plate of this utility model. Figure 3 for Figure 1 A right-side view of the lower side beams that make up the side wall. Figure 4 This is a three-dimensional schematic diagram of the lower side beam of this utility model. Figure 5 A front view schematic diagram of the lower side beam of this utility model.

Figure 7 This is a comparison diagram of the transverse cross-section of the upper side beam in the prior art and the transverse cross-section of the upper side beam of this utility model. Figure 8 This is a schematic diagram of the transverse cross-section of the lower side beam in the prior art.
[0042] In this embodiment, as Figure 1As shown, the sidewalls of the railway container transport vehicle consist of an upper side beam 21, a middle side plate 22, a lower side beam 23, an end side plate 24, a first column 25, and a second column 26. All of these are made of steel.
[0043] The length direction of the upper side beam 21, the middle side plate 22, and the lower side beam 23 is the same as the length direction of the railway container transport vehicle, and the upper side beam 21, the middle side plate 22, and the lower side beam 23 are connected sequentially from top to bottom.
[0044] like Figure 6 , Figure 7 (b) and Figure 1 As shown, the upper side beam 21 is a rectangular tubular shape and is vertically arranged. The length of the upper side beam 21 is greater than the length of the middle side plate 22. The thickness of the upper side beam 21 is greater than the thickness of the middle side plate 22. Figure 1 In the middle, the end of the upper beam 21 is provided with components (such as handrails and lugs, not marked in the figure), which will not be described in this embodiment.
[0045] The height of the rectangular tubular transverse section of the upper beam 21 is greater than twice the width of the transverse section. For example... Figure 7 As shown, compared with the upper side beam of the prior art (refer to...) Figure 7 Compared to (a)), the upper side beam 21 of this embodiment (refer to) Figure 7 (b) has a higher transverse section and a smaller width. This is beneficial for improving the load-bearing capacity of the vehicle body.
[0046] like Figure 1 and Figure 2 As shown, the middle side plate 22 is flat and vertically arranged. Multiple weight-reducing holes 221, for example, more than six, are provided on the middle side plate 22. The weight-reducing holes 221 are evenly distributed. The weight-reducing holes 221 can be elliptical, with their length direction being the same as the length direction of the middle side plate 22. The top of the middle side plate 22 is connected to the bottom of the upper side beam 21, for example, by welding them together. The center plane of the middle side plate 22 perpendicular to its length direction is coplanar with the center plane of the upper side beam 21 perpendicular to its length direction.
[0047] like Figures 3 to 6As shown, the lower beam assembly 23 includes a vertical section 231, a horizontal section 232, and a U-shaped section 233. The length directions of the vertical section 231, the horizontal section 232, and the U-shaped section 233 are all the same as the length direction of the railway container transport vehicle. The vertical section 231 is flat and vertically arranged. The horizontal section 232 is flat and horizontally arranged. One side of the horizontal section 232 is connected to the bottom of the vertical section 231, and the included angle between them is greater than 85° and less than 95°. Specifically, the bottom of the vertical section 231 and one side of the horizontal section 232 are connected by an arc-shaped structure, the curvature of which is greater than 85° and less than 95°, for example, 90°. The bottom surface of the vertical section 231 is higher than the upper surface of the horizontal section 232. In this embodiment, the horizontal section 232 and the arc-shaped structure can be integrally formed.
[0048] In this embodiment, the outer contour of the vertical portion 231 is an isosceles trapezoid, which has an upper base, a lower base, a first hypotenuse, and a second hypotenuse. The length of the upper base is greater than the length of the lower base. The length of the lower base is the same as the length of the horizontal portion 232, and the lower base is connected to the horizontal portion 232 by an arc-shaped structure. The angle between the first hypotenuse and the upper base is greater than 10° and less than 50°. The angle between the second hypotenuse and the upper base is greater than 10° and less than 50°. The thickness of the vertical portion 231 is the same as the thickness of the horizontal portion 232.
[0049] The U-shaped portion 233 has a U-shaped cross-section and is located below the horizontal portion 232. The top opening of the U-shaped portion 233 faces the horizontal portion 232 and is closed by the horizontal portion 232. The center plane of the U-shaped portion 233, perpendicular to the width direction, is perpendicular to the horizontal portion 232. The depth of the U-shaped portion 233 is greater than the thickness of the horizontal portion 232. The width of the U-shaped portion 233 is greater than half the width of the horizontal portion 232 and less than the width of the horizontal portion 232.
[0050] Combining with the lower side beam in the prior art (such as) Figure 8 Compared to the previous version, the new lower side beam assembly 23 can reduce its own weight while ensuring structural stability, making it more suitable for loading and transporting large containers on extended railway container transport vehicles.
[0051] The top of the vertical portion 232 of the lower side beam 23 (i.e., the lower base of the isosceles trapezoid) is connected to the bottom of the middle side plate 22, for example, by welding.
[0052] like Figure 1As shown, there are multiple first columns 25, all vertically arranged and spaced apart. A portion of the first columns 25 are located near the end of the middle side plate 22. At least a portion of the first columns 25 are connected to the outer surface of the middle side plate 22, the outer surface of the vertical portion 231 of the lower side beam 23, and the outer surface of the U-shaped portion 233 near the vertical portion 231, respectively; for example, they can be welded together. The first columns 25 can be stamped integral side columns, with enlarged bending radius, and the root of the first column 25 adopts an inward-curving structure (e.g., Figure 6 As shown), this minimizes the problem of high wind resistance caused by the outer columns. These outer surfaces are located away from the center plane perpendicular to the width direction of the railway container car, i.e., on the outer side of the car body. The top of the first column 25 and the bottom of the upper side beam 21 are also connected, for example, they can be welded together.
[0053] In this embodiment, the first column 25 is provided as three or more, for example, five. Four of them are evenly distributed near both ends of the middle side plate 22, and the other is near the middle of the middle side plate 22.
[0054] Multiple second columns 26 are provided, all vertically aligned and spaced apart. Each second column 26 is connected to the outer surface of the middle side plate 22 and the outer surface of the vertical portion 231 of the lower side beam 23, for example, they can be welded together. These outer surfaces are located away from the center plane of the railway container car, perpendicular to its width. The top of each second column 26 is also connected to the bottom of the upper side beam 21, for example, they can be welded together.
[0055] In this embodiment, there are eight or more second columns 26, and a weight-reducing hole 221 is provided between two adjacent second columns 26. The width and length of the second column 26 are smaller than the width and length of the first column 25, respectively. The thickness of the second column 26 is smaller than the thickness of the first column 25.
[0056] In this embodiment, both the first pillar 25 and the second pillar 26 are located on the outer side of the vehicle body. The brake lines can also pass through the first pillar 25 (not shown in the figure), so that the brake lines are arranged along the length of the middle side plate 22, and most of the brake lines are located on the outer side of the vehicle body, which is beneficial for the inspection and maintenance of the brake lines.
[0057] The end side plate 24 includes a first end side plate and a second end side plate, which are symmetrically arranged at both ends of the middle side plate 22. The top of the end side plate 24 is connected to the bottom of the upper side beam 21, and the bottom of the end side plate 24 is connected to the vertical part 231 of the lower side beam 23. The upper part of the end side plate 24 is provided with end side plate weight reduction holes. The area of the end side plate weight reduction holes is smaller than the area of the weight reduction holes 221 on the middle side plate 22.
[0058] In this embodiment, the width of one end of the end plate 24 connected to the middle side plate 22 is equal to the width of the middle side plate 22, while the width of the other end is less than the width of the middle side plate 22. The top surface of the end plate 24 is substantially coplanar with the top surface of the middle side plate 22. The bottom surface of the end plate 24 consists of a concave arc surface and a flat bottom, with the bottom surface near the middle side plate 22 being a flat bottom and substantially coplanar with the bottom surface of the middle side plate 22. The thickness of the end plate 24 is greater than the thickness of the middle side plate 22, meaning that the end plate 24 can be formed from a thicker steel plate. This is beneficial for improving load-bearing capacity.
[0059] Example 2
[0060] This embodiment provides a railway container transport vehicle, which includes multiple carriages. At least one carriage includes two sets of side walls as described in Embodiment 1. The two sets of side walls are symmetrically arranged with the central plane of the railway container transport vehicle perpendicular to the width direction as the symmetrical plane.
[0061] This utility model is not limited to the above-described embodiments. Any modifications, improvements, or substitutions that can be conceived by those skilled in the art without departing from the essential content of this utility model fall within the scope of this utility model.
