[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 11As shown, an embodiment of the present invention provides an open car, which includes a bottom bracket 10, a side wall 20, and an end wall 30. The bottom bracket 10 includes a transverse beam 11, a longitudinal beam 12 and a floor 13, and the transverse beam 11 and the longitudinal beam 12 are staggered on the floor 13; the side wall 20 is located at the side of the bottom bracket 10, and the side wall 20 includes a side plate 21 and a side column 22 arranged on the side plate 21, and the side column 22 extends vertically, and the lower end of the side plate 21 is riveted to the side of the floor 13, and the lower end of the side column 22 is riveted to the transverse beam 11; the end wall 30 is located at the end of the bottom bracket 10, and the end wall 30 includes an end plate 31 and an end column 32 arranged on the end plate 31, and the end column 32 extends vertically, and the lower end of the end plate 31 is riveted to the end of the floor 13, the side of the end plate 31 is riveted to the side plate 21, and the end column 32 is riveted to the longitudinal beam 12.

[0040] By applying the technical solution of the present invention, the open car includes a bottom bracket 10, a side wall 20 and an end wall 30. The bottom bracket 10 is placed on an assembly table, the side wall 20 and the end wall 30 are placed on the bottom bracket 10 respectively, and the relative positions of the side wall 20 and the end wall 30 are adjusted. After the requirements are met, the floor 13 is riveted to the side plate 21 and the end plate 31 respectively, the side column 22 is riveted to the transverse beam 11, and the end column 32 is riveted to the longitudinal beam 12, and the assembly of the open car can be completed. Compared with the method of welding the bottom bracket 10, the side wall 20 and the end wall 30, there is no need for large-scale turning equipment, and the welding workload is greatly reduced, the long weld between the bottom plate and the side plate 21 is omitted, and a large number of welders are not required, which reduces environmental pollution and manufacturing costs.

[0041] In this embodiment, the side pillars 22 are located inside the side panels 21, which enables the open car to have a larger volume compared to a solution in which the side pillars 22 are located outside.

[0042] There are two side walls 20 and two end walls 30 , the two side walls 20 are respectively located at two sides of the bottom bracket 10 , and the two end walls 30 are respectively located at two ends of the bottom bracket 10 .

[0043] like Figure 1 and Figure 2 As shown, the side column 22 is located in the side plate 21, and the side column 22 includes a column body 221 and a connecting plate 222 connected to the lower end of the column body 221. The connecting plate 222 is located above the floor 13, and the rivets pass through the connecting plate 222 and the floor 13 to be riveted to the transverse beam 11. The side column 22 with the above structure uses the column body 221 to support the side plate 21, and uses the connecting plate 222 to be riveted to the floor 13, which has the advantages of simple structure and easy assembly.

[0044] like Figure 2 As shown, the connecting plate 222 includes an inclined plate 2221 and a riveted plate 2222 connected to each other, the inclined plate 2221 is inclined, the riveted plate 2222 is parallel to the floor 13, the inclined plate 2221 is connected to the column 221, and the rivets pass through the riveted plate 2222 and the floor 13 and are riveted to the transverse beam 11. By using the above-mentioned connecting plate 222, the inclined plate 2221 is used to eliminate the right angle of connection between the column 221 and the floor 13, so as to avoid the accumulation of materials that are difficult to clean. The riveted plate 2222 is used to realize the riveting of the side column 22 and the floor 13.

[0045] The inclined plate 2221 may be configured as a bent structure with multiple bends for easy connection. The inclined plate 2221 and the riveted plate 2222 are welded together, and the multiple bent structures are also welded together.

[0046] In this embodiment, the inclined plate 2221 is connected to the column 221 by welding.

[0047] In other embodiments, the floor 13 is provided with an escape notch, the lower end of the side column 22 passes through the escape notch, and the lower end of the side column 22 is riveted to the end wall of the transverse beam 11. With the above structure, by making the side column 22 pass through the floor 13 and riveted to the end of the transverse beam 11, the connection strength between the two can be enhanced.

[0048] Among them, a shielding plate needs to be connected to the side wall of the side column 22 to shield the avoidance gap.

[0049] like Figure 4 and Figure 6 As shown, the floor 13 includes a floor plate body 131 and a bottom folded plate 132 connected to the side of the floor plate body 131, and the side plate 21 includes a side plate body 211 and a side folded plate 212 connected to the lower end of the side plate body 211. The side folded plate 212 and the bottom folded plate 132 are both located on the inner side of the side plate body 211, and the bottom folded plate 132 and the side folded plate 212 are riveted together. The above structure can avoid the limit, ensure the connection quality of the gondola when the gondola has a larger volume, and has the advantages of simple structure and easy operation.

[0050] In this embodiment, the side folded plate 212 is located on the inner side of the bottom folded plate 132 , and the connecting plate 222 is butted against the lower end of the bottom folded plate 132 and connected by welding.

[0051] The bottom folding plate 132 and the side folding plate 212 can be set as a plate structure with only one bend or a plate structure with multiple bends. When only one bend is used, the rivet extends obliquely to increase the volume of the vehicle body. When multiple bends are used, the rivet extends horizontally for easy operation.

[0052] In this embodiment, the bottom folding plate 132 and the side folding plate 212 are both inclined, which has the advantages of simple structure and easy processing.

[0053] Among them, the advantage of overlapping the side plate 21 and the floor 13 at the inclined surface is that it not only avoids the right-angle structure at the intersection of the side plate 21 and the floor 13, which causes the goods to be unloaded incompletely, but also makes full use of the inclined surface structure, reserves the space required for the rivet ring, avoids the interference of the rivet with the vehicle limit, and can ensure that the vertical surface of the side plate 21 is as close to the vehicle limit as possible, thereby increasing the volume of the vehicle body. In addition, the bending structure of the side plate 21 and the floor 13 can improve the rigidity of the side plate 21 and the floor 13 to a certain extent, reduce the deformation of the side plate 21 and the floor 13 during the transportation of large parts, and improve the flatness of the side plate 21.

[0054] like Figure 4 and Fig.11 As shown, the gondola also includes a support block 40, which is correspondingly arranged below the side column 22, and the support block 40 is respectively in contact with the bottom folded plate 132 and the transverse beam 11. The support block 40 can support the bottom folded plate 132 and the side folded plate 212 to avoid deformation, thereby enhancing the service life of the gondola.

[0055] like Figure 4 As shown, the floor 13 includes a floor plate body 131 and an end folded plate 133 connected to the end of the floor plate body 131, and the upper end of the end folded plate 133 is riveted to the lower end of the end plate 31. The above connection structure can be used to rivet the floor 13 and the end plate 31, which has the advantages of simple structure and easy operation.

[0056] Specifically, the floor 13 further includes an inclined end reinforcement plate 134, the upper end of the end reinforcement plate 134 is connected to the end folded plate 133, and the lower end of the end reinforcement plate 134 is connected to the floor 13. The end reinforcement plate 134 can eliminate the right-angle connection, thereby preventing materials from piling up at the right angles, which is inconvenient to clean.

[0057] like Figures 8 to 10 As shown, the end column 32 is located outside the end folded plate 133, the lower end of the end column 32 protrudes from the lower surface of the end folded plate 133, the end of the longitudinal beam 12 protrudes from the side wall of the end folded plate 133, the lower end of the end column 32 is riveted to the portion of the longitudinal beam 12 protruding from the end folded plate 133, and the side wall of the end column 32 is riveted to the end folded plate 133. The above structure can make the end column 32 and the longitudinal beam 12 riveted, which has the advantages of simple structure and easy operation.

[0058] like Fig. 9 and Fig.10As shown, the floor 13, the end folded plate 133 and the end reinforcing plate 134 form a cavity, the floor 13 is provided with a floor through hole 135, the end folded plate 133 is provided with a folded plate through hole 1331, and the floor through hole 135 and the folded plate through hole 1331 are both connected to the cavity. Due to the shielding of the end reinforcing plate 134, the operator can operate through the floor through hole 135 and the folded plate through hole 1331 to rivet the end column 32 and the end folded plate 133.

[0059] Furthermore, since the end reinforcement plate 134 shields the floor through hole 135 and the folding plate through hole 1331, the cargo in the open car will not leak.

[0060] like Fig. 9 and Fig.10 As shown, the open car also includes an end connecting plate 50, which includes a U-shaped plate 51, a first extension plate 52 and a second extension plate 53. The U-shaped plate 51 is arranged on the end folded plate 133 and covers the outer side of the end column 32. The first extension plate 52 and the second extension plate 53 are respectively connected to the two sides of the end column 32. The first extension plate 52 and the second extension plate 53 are respectively riveted to the end folded plate 133, and the bottom wall of the U-shaped plate 51 is riveted to the end column 32. The end connecting plate 50 is used, the first extension plate 52 and the second extension plate 53 are respectively connected to the end folded plate 133, and the U-shaped plate 51 is connected to the end column 32, which has the advantages of simple structure and easy operation.

[0061] The operator reaches into the end column 32 through the floor through hole 135 and the folding plate through hole 1331 , and rivets the end column 32 and the U-shaped plate 51 .

[0062] like Figure 5 As shown, the side panel 21 includes a side panel body 211 and a corner folded plate 213 provided on the side of the side panel body 211, the corner folded plate 213 extends vertically, and the side of the end panel 31 is riveted to the corner folded plate 213. With the side panel 21 having the above structure, the side panel body 211 and the end panel 31 can be connected by using the corner folded plate 213.

[0063] A plurality of wear plates are disposed on the outer side of the side plate body 211, and the positions of the wear plates correspond to the support plates of the tipping machine, so as to prevent the side plate body 211 from being worn when the tipping machine is unloading.

[0064] like Figure 3 As shown, the open car further includes a corner connecting plate 60, which is respectively connected to the side wall 20 and the end wall 30. The side wall 20 and the end wall 30 can be pre-connected by using the corner connecting plate 60 to connect and fix the two.

[0065] Among them, the corner connecting plate 60 is connected to the side wall 20 and the end wall 30 by bolts. The side wall 20 also includes a side beam arranged at the upper end of the side plate 21, and the end wall 30 also includes an end beam arranged at the upper end of the end plate 31. The corner connecting plate 60 includes a first L-shaped plate and a second L-shaped plate connected to each other. The first L-shaped plate is connected to the side plate 21 and the end plate 31 respectively, and the second L-shaped plate is connected to the side beam and the end beam respectively. By using the above-mentioned corner connecting plate 60, the side and top of the side wall 20 and the end wall 30 can be connected respectively, so that the pre-connection effect is more stable.

[0066] In this embodiment, the diameters of all rivet holes are the same, which reduces the specifications of the rivets. In addition, the collars of the rivets are all located on the outside of the vehicle body, which is conducive to unloading the goods.

[0067] The application of the open wagon provided in this embodiment has the following beneficial effects:

[0068] (1) The bottom bracket 10, the side wall 20, and the end wall 30 of the open car are all connected by riveting, without welds, which reduces the welding workload and does not require large tooling equipment such as a turning machine. Since the riveting operation is simpler than the welding operation, this solution reduces the difficulty of assembly and improves the assembly efficiency.

[0069] (2) It avoids the emission of welding fumes and realizes green manufacturing during the assembly of open wagons, which is particularly suitable for manufacturing in areas with high environmental protection requirements.

[0070] (3) The vehicle has a large volume due to the built-in side pillars and no lower side beams.

[0071] (4) The manufacturing process is fully considered, and all rivets are inserted from the inner side of the car body to the outer side of the car body, which has good riveting process and is easy to operate.
