Description

DETAILED DESCRIPTION

[0042] The core of the present application is to provide an end side wall connecting structure for an open wagon, which can realize the light weight of the open wagon while ensuring the reliability of the end side wall connection of the open wagon.

[0043] Another key aspect of this application is to provide a wagon with the aforementioned end-side wall connection structure for wagons.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Traditional coal-carrying open wagons typically employ an all-steel welded structure, where the steel end walls and side walls are welded together as a single unit. While this method offers high connection strength, the high density of steel results in excessive wagon weight, increasing traction energy consumption and reducing transportation efficiency. Furthermore, the enormous size of the wagons makes it difficult to collect and manage the large amounts of welding fumes generated during the overall welding process, failing to meet the green and environmentally friendly requirements of modern manufacturing.

[0046] Therefore, such as Figure 1 As shown in the figure, this application discloses an end wall connection structure 100 for a convertible, including an end wall 10, a side wall 20, and a corner connection assembly 30. Through the corner connection assembly 30 and the plug-in connection method, different components of the end wall 10 and the side wall 20 are specifically connected to form a complete non-welded connection structure, thereby ensuring the reasonable transfer of loads in the vehicle body structure, effectively bearing and transmitting longitudinal impact loads, and ensuring the safety and reliability of the entire vehicle structure. Simultaneously, by using lightweight alloys as the main materials for the end wall 10 and the side wall 20, and replacing traditional large-scale welding operations with fastener connections, the vehicle body weight is significantly reduced, saving operating energy consumption. Furthermore, it avoids the smoke and dust pollution generated during the welding process, greatly improving the green level of the manufacturing process. Moreover, the connection structure design of each component is simple, facilitating the modular design of the end wall 10 and the side wall 20. The plug-in connection method of the end crossband 11 and the side crossband 21 can play a role in rapid positioning and guidance during assembly, simplifying the assembly process and improving production efficiency.

[0051] In some embodiments, as shown in Figure 9 , the mounting groove 40 can have a slot 41 capable of inserting the plug-in part 50, wherein the mounting groove 40 can extend towards the outside, that is, the mounting groove 40 can extend towards the edge away from the end wall 10 or the side wall 20, so as to form the slot 41 for inserting the plug-in part 50, while the plug-in part 50 can be inserted into the mounting groove 40 from the slot 41 along the direction perpendicular to the bottom wall of the mounting groove 40, and riveted into the side wall of the mounting groove 40 and the plug-in part 50 from one side of the side wall of the mounting groove 40 by the first fastener 31, so as to realize the reliable connection between the end cross belt 11 of the end wall 10 and the side cross belt 21 of the side wall 20, as shown in Figure 11 .

[0054] In some embodiments, as shown in Figure 1 and Figure 3 , the end wall 10 can include an end plate 12 and an end wall beam 13 connected to the top of the end plate 12. The end plate 12 can be made of aluminum alloy plate to play a containment role to prevent leakage of goods. The end wall beam 13, as the main load-bearing component of the end wall 10, can be made of aluminum alloy material and manufactured by extrusion process to improve its strength, and the end wall beam 13 and the end plate 12 can be connected and fixed by riveting. At the same time, the connecting flanges of the end cross strip 11 can be riveted to the end plate 12 to increase the lateral stiffness of the end plate 12 to resist the lateral pressure of the goods on the end plate 12. Accordingly, as shown in Figure 1 and Figure 4As shown, the side wall 20 can include a side plate 22 and a side wall beam 23 connected to the top of the side plate 22, and the side plate 22 can be made of aluminum alloy plate to play a role of enclosure to prevent leakage of goods, and the side wall beam 23 as the main load-bearing component of the side wall 20 can be made of aluminum alloy material and manufactured by extrusion process to improve its strength, and the side wall beam 23 and the side plate 22 can be fixed by riveting connection. At the same time, the side cross belt 21 can be riveted on the side plate 22 to increase the lateral stiffness of the side plate 22 to resist the lateral pressure of the goods on the side plate 22.

[0055] In some embodiments, as shown in Figure 1 and Figure 2 The corner connecting assembly 30 can include a first corner connecting piece 32 and a second corner connecting piece 33. Among them, the first corner connecting piece 32 can be arranged at the connecting position of the end plate 12 and the side plate 22, and the first corner connecting piece 32 can be riveted and fixed with the end plate 12 and the side plate 22 by the first fastener 31 respectively. At the same time, the second corner connecting piece 33 can be arranged at the connecting position of the end wall beam 13 and the side wall beam 23, and the second corner connecting piece 33 can be riveted and fixed with the end wall beam 13 and the side wall beam 23 by the first fastener 31 respectively.

[0056] In some embodiments, as shown in Figure 1 , Figure 5 and Figure 8 The first corner connecting piece 32 can connect the end plate 12 and the side plate 22, and can extend along the height direction of the open car, and cover the outside of the corner of the end plate 12 and the side plate 22, to ensure the sealing of the connection of the end plate 12 and the side plate 22, and prevent leakage of goods. Among them, the first corner connecting piece 32 can be made of aluminum alloy material and manufactured by extrusion process, and the first corner connecting piece 32 can have two first connecting parts 321 perpendicular to each other to form an L-shaped structure, so that the two first connecting parts 321 can be riveted and fixed with the end plate 12 and the side plate 22 by the first fastener 31 respectively. When assembling, the first corner connecting piece 32 is arranged outside the open car formed by the end wall 10 and the side wall 20, and the concave surface of the L-shaped first corner connecting piece 32 covers and fits the outside corner formed by the end plate 12 and the side plate 22, and is riveted and fixed. As shown in Figure 5 and Figure 8As shown, the two first connecting portions 321 of the first corner connecting piece 32 and the corresponding end plate 12 and side plate 22 are provided with preformed connecting holes, so that a plurality of rivets or other first fasteners 31 can pass through the preformed connecting holes to rivet one first connecting portion 321 of the first corner connecting piece 32 with the edge region of the end plate 12, and rivet the other first connecting portion 321 of the first corner connecting piece 32 with the edge region of the side plate 22. In this way, the end plate 12 and the side plate 22 are firmly combined, and the first corner connecting piece 32 itself can act as an important reinforcing column of the open car corner, greatly improving the impact resistance and deformation resistance of the corner region, and forming a smooth and continuous open car inner surface, thereby increasing the volume of the open car.

The second corner connecting piece 33 can be made of high-strength carbon steel material, such as structural steel of Q345 or the like, to achieve lightweight while providing sufficient strength and rigidity to the critical stress point of the top corner of the open car. In addition, the second corner connecting piece 33 can have two second connecting portions 331 arranged perpendicular to each other to form an L-shaped structure, so that the two second connecting portions 331 can be riveted and fixed to the end wall beam 13 and the side wall beam 23, respectively, by using rivets or other first fasteners 31. When assembling, the second corner connecting piece 33 is arranged inside the open car formed by the end wall 10 and the side wall 20, and one of the two second connecting portions 331 of the second corner connecting piece 33 is flush with the inner side wall of the end wall beam 13, and the other second connecting portion 331 of the second corner connecting piece 33 is flush with the inner side wall of the side wall beam 23, so that the second corner connecting piece 33 can effectively lap the joint between the end wall beam 13 and the side wall beam 23. In order to achieve the connection and fixation of the second corner connecting piece 33, the two second connecting portions 331 of the second corner connecting piece 33 and the corresponding end wall beam 13 and side wall beam 23 are provided with a plurality of aligned connecting holes, so that a plurality of rivets or other first fasteners 31 can pass through the aligned connecting holes to tightly rivet the second corner connecting piece 33, the end wall beam 13 and the side wall beam 23. By arranging multiple rows and columns of rivets or other first fasteners 31, the reliability of the connection can be ensured, so that the longitudinal load acting on the end wall beam 13 can be smoothly transmitted to the side wall beam 23 through the second corner connecting piece 33, and the transverse load acting on the side wall beam 23 can also be smoothly transmitted to the end wall beam 13 through the second corner connecting piece 33, thereby ensuring the stability and load-bearing capacity of the entire open car top frame structure.

The side post 24 can be riveted and fixed to the side wall beam 23. The side post 24, the side wall beam 23, and the end wall beam 13 can form a stable frame structure together, thereby ensuring the stability of the open car.

[0059] In some embodiments, as shown in Figure 1 and Figure 10 The side post 24 can be made of an aluminum alloy material and manufactured by an extrusion process to achieve lightweighting while improving the strength and rigidity of the side post 24. The side post 24 can be provided with a third connecting portion 241, and the third connecting portion 241 can extend from the side post 24 toward a direction away from the side post 24. The side portion crossband 21 and the side plate 22 can be connected to opposite sides of the third connecting portion 241, respectively. The side plate 22 can be connected to a side of the third connecting portion 241 close to the interior of the open car, and the side portion crossband 21 can be connected to a side of the third connecting portion 241 away from the interior of the open car. In addition, the side portion crossband 21 and the side plate 22 can share a second fastener such as a rivet to be riveted and fixed to the third connecting portion 241. The rivet can pass through the side portion crossband 21, the third connecting portion 241, and the side plate 22 in sequence to achieve riveted connection between the side portion crossband 21, the side plate 22, and the side post 24. This can reduce the number of parts, simplify the assembly process, and improve the assembly efficiency.
