Description

Technical Field

[0001] This application relates to the field of coal mine vehicle technology, and more specifically, to a sidewall structure for an open wagon and the open wagon itself. Background Technology

[0002] In the design of freight vehicles, especially bulk cargo transport vehicles such as open coal wagons, effective volume is a key indicator for measuring their transport efficiency. In order to increase loading volume under the condition of limited overall vehicle dimensions, the thickness of the side walls of the wagon is usually reduced to increase the interior space of the open wagon.

[0003] Traditional open wagons typically use a plate-and-column structure for their side walls, consisting of side panels and external pillars. This structure provides the structural rigidity required to resist cargo pressure by riveting multiple pillars to the outside of the relatively thin side panels. However, this results in a large overall thickness of the side wall, which limits the effective width and volume inside the open wagon.

[0004] Therefore, how to increase the interior space of a convertible while ensuring the rigidity of the vehicle body sidewalls has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a side wall structure for a convertible, so as to increase the interior space of the convertible while ensuring the rigidity of the side wall of the vehicle body.

[0006] Another object of this application is to provide a wagon having the aforementioned sidewall structure for a wagon.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A sidewall structure for a convertible, comprising:

[0009] The columns include a plurality of columns spaced apart.

[0010] A wall panel is disposed between two adjacent columns. Each column has a mounting groove that can accommodate the end of the wall panel. The wall panel has a mounting part that is adapted to the mounting groove. The mounting part can be embedded in the mounting groove and welded and fixed. The wall panel and the columns are located on the same plane on the side facing the interior of the open wagon.

[0011] Both the columns and the wall panels are hollow extruded profiles.

[0012] Optionally, in the above-described sidewall structure, the column is provided with a first connecting portion and a second connecting portion. The first connecting portion and the side of the column facing the interior of the open wagon are located on the same plane, and the first connecting portion extends in a direction away from the column. The second connecting portion and the side of the column away from the interior of the open wagon are located on the same plane, and the second connecting portion extends in a direction away from the column. The mounting groove is formed between the first connecting portion and the second connecting portion.

[0013] Optionally, in the above-described sidewall structure, the length of the first connecting portion is greater than the length of the second connecting portion.

[0014] Optionally, in the above-described sidewall structure, a notch is formed between the mounting portion and the side of the wall panel facing the interior of the convertible to accommodate the first connecting portion.

[0015] Optionally, in the above-described sidewall structure, the column has a first cavity, and the mounting groove is symmetrically arranged on both sides of the first cavity along the width direction of the column.

[0016] Optionally, in the above-described sidewall structure, the wall panel has at least one second cavity, and the mounting portion is symmetrically arranged on both sides of the second cavity along the width direction of the wall panel.

[0017] Optionally, the above-mentioned side wall structure also includes a top beam, which is a hollow extruded profile. The top beam has a third connecting part, which is located on the same plane as the side of the top beam facing the interior of the open wagon. The upper ends of the column and the wall panel are both connected to the side of the third connecting part away from the interior of the open wagon and fixed by multiple fasteners.

[0018] Optionally, in the above-mentioned side wall structure, a positioning protrusion is provided at the bottom of the top beam. The positioning protrusion is on the same plane as the side of the top beam that is away from the interior of the open wagon, and the positioning protrusion is used to position the installation position of the column.

[0019] Optionally, in the above-mentioned side wall structure, the columns, the wall panels, and the top beams are all aluminum alloy extruded profiles with rectangular cross-section cavities.

[0020] A convertible, comprising the sidewall structure as described in any of the preceding claims.

[0021] The side wall structure for open wagons provided in this application involves placing wall panels between two adjacent uprights, with the mounting portion of the wall panels embedded in the mounting grooves of the uprights and welded in place. The side of the wall panels and uprights facing the interior of the open wagon are on the same plane, and both the wall panels and uprights are made of hollow extruded profiles. As can be seen from the above example, the side wall structure for open wagons provided in this application, by using hollow profiles for both the wall panels and uprights and welding them together, can significantly reduce the thickness of the side walls while ensuring structural rigidity. This effectively increases the internal volume and load capacity of the vehicle, improving transportation efficiency. Furthermore, the flat inner wall facilitates the smooth sliding out of bulk cargo, avoiding material snagging during unloading and improving loading and unloading efficiency. Simultaneously, the use of hollow profiles for both the wall panels and uprights provides high structural rigidity, effectively resisting cargo pressure, reducing side wall expansion deformation, improving vehicle operational reliability, and achieving lightweight and thin-walled design of the vehicle body, further increasing the vehicle's effective load and volume.

Detailed Implementation

[0030] The core of this application is to provide a side wall structure for a convertible that can increase the interior space of the convertible while ensuring the rigidity of the side wall.

[0031] Another key aspect of this application is to provide a wagon with the aforementioned sidewall structure for wagons.

[0032] 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.

[0033] In the design of freight vehicles, especially bulk cargo transport vehicles such as open coal wagons, effective volume is a key indicator for measuring their transport efficiency. In order to increase loading volume under the condition of limited overall vehicle dimensions, the thickness of the side walls of the wagon is usually reduced to increase the interior space of the open wagon.

[0034] Traditional open wagons typically use a plate-and-column structure for their side walls, consisting of side panels and external pillars. This structure provides the structural rigidity required to resist cargo pressure by riveting multiple pillars to the outside of the relatively thin side panels. However, this results in a large overall thickness of the side wall, which limits the effective width and volume inside the open wagon.

[0035] Therefore, such as Figure 1 As shown in the illustration, this application discloses a sidewall structure 100 for an open wagon, including columns 10 and wall panels 20. By using hollow profiles for both the wall panels 20 and columns 10 and fixing them together through interlocking welding, the sidewall thickness can be significantly reduced while maintaining the rigidity of the sidewall structure 100. This effectively increases the vehicle's internal volume and load capacity, improving transportation efficiency. Furthermore, the smooth inner wall facilitates the smooth sliding out of bulk cargo, preventing material snagging during unloading and improving loading and unloading efficiency. Simultaneously, the use of hollow profiles for both the wall panels 20 and columns 10 provides high structural rigidity, effectively resisting cargo pressure, reducing sidewall expansion deformation, improving vehicle operational reliability, and achieving lightweight and thin-walled design of the vehicle body, further increasing the vehicle's effective load and volume.

[0036] The following will combine Figures 1 to 5The side wall structure 100 for open wagons disclosed in the embodiments of this application will be explained and described in detail.

[0037] like Figure 1 As shown, the columns 10 can be set along the height direction of the open wagon, that is, the columns 10 extend towards the height direction of the open wagon, and multiple columns 10 can be distributed at intervals along the length direction of the open wagon. At the same time, the wall panels 20 are located between two adjacent columns 10, and along the length direction of the open wagon, the wall panels 20 and columns 10 are arranged alternately to form the side wall structure 100.

[0038] To achieve both lightweight and high strength in the side wall structure 100, both the columns 10 and wall panels 20 can be made of hollow extruded profiles. This allows for a significant reduction in side wall thickness while maintaining the rigidity of the side wall structure 100, thereby effectively increasing the vehicle's internal volume and load capacity, improving transportation efficiency, and effectively resisting cargo pressure, reducing side wall expansion deformation, and improving vehicle operational reliability. In this embodiment, both the columns 10 and wall panels 20 are preferably made of aluminum alloy hollow extruded profiles, which have advantages such as low density, high strength, and corrosion resistance. Furthermore, the extrusion molding process can produce hollow profiles with complex cross-sectional shapes in a single step, thereby improving the production efficiency of the side wall structure 100.

[0039] In some embodiments, such as Figure 2 As shown, the column 10 can be made of aluminum alloy extruded profile with a rectangular cross-section cavity, which helps to improve the strength and stability of the column 10. At the same time, the rectangular cross-section cavity has excellent bending strength and stiffness, which can effectively resist external loads and deformation, thereby improving the lateral stiffness of the column 10 to resist coal pressure and effectively prevent the vehicle body from expanding beyond the limit. In addition, the aluminum alloy extruded profile with a rectangular cross-section cavity can make fuller use of the material, that is, the rectangular cross-section area is larger, which can reduce the overall weight while ensuring strength and improve the material utilization efficiency.

[0040] In some embodiments, such as Figure 3 As shown, the wall panel 20 can be made of extruded aluminum alloy profile with a rectangular cross-section cavity, and multiple longitudinal stiffeners can be set inside the rectangular cross-section cavity. Each stiffener can divide the rectangular cross-section cavity into multiple parallel and independent rectangular chambers. The multi-chamber structure not only greatly improves the local stiffness and stability of the wall panel 20 itself, enabling it to evenly bear and distribute the pressure of goods acting on its surface, but also provides a better energy absorption and cushioning effect in the event of an accidental impact.

[0041] like Figures 2 to 4As shown, the column 10 may have a mounting groove 11, and the wall panel 20 has a mounting part 21. The mounting part 21 at the end of the wall panel 20 can be embedded in the mounting groove 11 and reliably connected and fixed by welding, preventing the connection between the wall panel 20 and the column 10 from loosening after the side wall structure 100 is impacted, thereby improving the reliability of the connection between the wall panel 20 and the column 10. At the same time, the inner sides of the wall panel 20 and the column 10, that is, the sides of the wall panel 20 and the column 10 facing the interior of the open wagon, are located on the same plane, which can effectively increase the internal volume and load capacity of the vehicle, improve transportation efficiency, and the flat inner wall facilitates the smooth sliding out of bulk cargo, avoids the phenomenon of material snagging during unloading, and improves the efficiency of loading and unloading operations.

[0042] In some embodiments, such as Figure 2 As shown, the column 10 may be provided with a first connecting portion 12 and a second connecting portion 13. The first connecting portion 12 may be located on the same plane as the inner side of the column 10, that is, the first connecting portion 12 may be coplanar with the side of the column 10 facing the interior of the wagon, and the first connecting portion 12 may extend in a direction away from the column 10. Simultaneously, the second connecting portion 13 may be located on the same plane as the outer side of the column 10, that is, the second connecting portion 13 may be coplanar with the side of the column 10 away from the interior of the wagon, and the second connecting portion 13 may extend in a direction away from the column 10. A mounting groove 11 may be formed between the first connecting portion 12 and the second connecting portion 13, so that the mounting portion 21 of the wall panel 20 can be embedded in the mounting groove 11 between the first connecting portion 12 and the second connecting portion 13. Figure 4 As shown.

[0043] In some embodiments, such as Figure 2 and Figure 4 As shown, the length of the first connecting part 12, i.e., the distance the first connecting part 12 extends away from the column 10 in the length direction of the open wagon, can be greater than the length of the second connecting part 13, i.e., the distance the second connecting part 13 extends away from the column 10 in the length direction of the open wagon. This allows for a larger welding area between the first connecting part 12 and the mounting part 21 of the wall panel 20, ensuring the reliability of the connection between the first connecting part 12 and the mounting part 21 of the wall panel 20. At the same time, the mounting part 21 of the wall panel 20 can overlap the second connecting part 13 and be fixed by welding to ensure the reliability of the connection between the wall panel 20 and the column 10. In addition, the second connecting part 13 can extend to the end wall position of the mounting part 21 near the column 10 to reduce the contact area between the weak area on the outside of the mounting part 21 and the second connecting part 13. This allows the supporting force of the second connecting part 13 to be transferred from the end wall of the mounting part 21 to the entire side wall structure 100, ensuring the reliability of the connection between the wall panel 20 and the column 10.

[0044] In some embodiments, such as Figure 3As shown, a notch 22 is formed between the mounting part 21 and the inner side of the wall panel 20, i.e., the side of the wall panel 20 facing the interior of the open wagon, to accommodate the first connecting part 12. This allows the first connecting part 12 to be located within the notch 22, and the inner side of the first connecting part 12 and the inner side of the wall panel 20 to be on the same plane. During assembly, the mounting part 21 of the wall panel 20 can be inserted into the mounting groove 11 of the column 10, while the first connecting part 12 is located within the notch 22 and fits tightly against the end face of the notch 22. This ensures that the inner side of the first connecting part 12 and the inner side of the wall panel 20 are on the same plane. Then, they are connected and fixed by welding to ensure the reliability of the connection.

[0045] In some embodiments, such as Figure 2 and Figure 4 As shown, the column 10 may have a first cavity 14 with a rectangular cross-section, and two mounting slots 11 may be used. These two mounting slots 11 are symmetrically arranged on both sides of the first cavity 14 along a direction parallel to the width of the column 10, i.e., the length of the open wagon, so that the column 10 can be inserted and connected to the wall panels 20 on both sides. Figure 4 As shown.

[0046] In some embodiments, such as Figure 3 and Figure 4 As shown, the wall panel 20 may have at least one second cavity 23 with a rectangular cross-section, that is, there may be one, two or more second cavities 23. At the same time, there may be two mounting parts 21, and the two mounting parts 21 may be symmetrically arranged on both sides of the second cavity 23 along the width direction parallel to the width direction of the wall panel 20, that is, the length direction of the open wagon, so that the wall panel 20 can be plugged and connected to the columns 10 on both sides.

[0047] The side wall structure 100 for open wagons disclosed in this application embodiment is constructed by placing a wall panel 20 between two adjacent columns 10, and embedding the mounting portion 21 of the wall panel 20 into the mounting groove 11 of the column 10 and welding it in place. The side of the wall panel 20 and the column 10 facing the interior of the open wagon are located on the same plane, and both the wall panel 20 and the column 10 are made of hollow extruded profiles.

[0048] The side wall structure 100 for open wagons disclosed in this application uses hollow profiles for both the wall panels 20 and the columns 10, which are welded together in an interlocking structure. This significantly reduces the side wall thickness while maintaining the rigidity of the side wall structure 100, thereby effectively increasing the vehicle's internal volume and load capacity, improving transportation efficiency. Furthermore, the flat inner wall facilitates the smooth sliding out of bulk cargo, preventing material snagging during unloading and improving loading and unloading efficiency. Simultaneously, the hollow profiles of both the wall panels 20 and the columns 10 provide high structural rigidity, effectively resisting cargo pressure, reducing side wall expansion deformation, improving vehicle operational reliability, and achieving lightweight and thin-walled design of the vehicle body, further increasing the vehicle's effective load and volume.

[0049] In some embodiments, such as Figure 1 and Figure 5 As shown, the side wall structure 100 may further include a top beam 30, which may be made of hollow extruded profile to meet the requirements of lightweighting and high strength. In this embodiment, the top beam 30 may be made of aluminum alloy extruded profile with an approximately rectangular cross-section cavity to meet the requirements of lightweighting while improving the strength and stability of the top beam 30. The top beam 30 may have a third connecting part 31, and the third connecting part 31 and the inner side of the top beam 30 are located on the same plane, that is, the third connecting part 31 and the side of the top beam 30 facing the interior of the open wagon are coplanar. The upper ends of the column 10 and the wall panel 20 may overlap the outer side of the third connecting part 31, that is, the side of the third connecting part 31 away from the interior of the open wagon, and can be riveted and fixed by multiple rivets and other fasteners 40, so that the top beam 30 and the column 10 can form a stable load-bearing frame structure of the side wall structure 100, while the wall panel 20 can provide a protective effect to prevent cargo leakage.

[0050] In some embodiments, such as Figure 5 As shown, a positioning protrusion 32 can be provided at the bottom of the top beam 30, and the positioning protrusion 32 can be on the same plane as the outer side of the top beam 30, that is, the side of the top beam 30 away from the interior of the open wagon. At the same time, the positioning protrusion 32 can extend along the axial direction of the top beam 30, that is, the length direction of the open wagon, so as to achieve precise positioning of the installation position of the column 10 through the positioning protrusion 32, thereby improving the installation efficiency between the column 10, the wall panel 20 and the top beam 30. During assembly, the top of the column 10 is abutted against the positioning protrusion 32. At this time, the column 10 and the wall panel 20 can be riveted and fixed to the third connection part 31 of the top beam 30 by multiple fasteners such as rivets 40, thereby realizing the rapid installation between the column 10, the wall panel 20 and the top beam 30.
