Description

Technical Field

[0001] This utility model relates to the field of wide-body vehicle technology, specifically to a ring beam structure and a wide-body vehicle. Background Technology

[0002] Wide-body trucks generally refer to large transport vehicles with wider bodies. For example, mining wide-body trucks are heavy-duty off-highway dump trucks mainly used in open-pit coal mines, stone mines, and other transportation industries. Wide-body trucks can have a maximum gross weight of around 150 tons when fully loaded, resulting in heavy daily operating loads. In addition, mining roads are often steep, muddy, and full of potholes, making the operating environment for mining wide-body trucks extremely harsh. The chassis is the core load-bearing component of a wide-body truck. The rectangular ring beam at the front of the chassis is typically a rectangular ring structure. To ensure structural strength, the rectangular ring beam is usually welded integrally to the longitudinal beams of the chassis main body. The rectangular space inside is generally used to install and secure the vehicle's power system.

[0003] However, after long-term use, the integral welded rectangular ring beam is prone to stress concentration at its right-angle corners, leading to structural deformation, cracking and other instability. At the same time, when maintaining the vehicle's power system, the integral welded structure hinders maintenance operations such as removing the engine from the power system, making maintenance inconvenient and affecting the efficiency of maintenance work. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to improve the convenience of maintenance and repair while ensuring the strength of the ring beam structure.

[0005] This utility model provides a ring beam structure for a wide-body vehicle frame. The ring beam structure includes an upper ring beam and a lower ring beam. The upper ring beam has an inverted U-shape and two first rounded corner bends symmetrically arranged on its upper part. The lower ring beam has a U-shape and two second rounded corner bends symmetrically arranged on its lower part. The frame includes two parallel longitudinal beams. The two lower ends of the upper ring beam are detachably connected to the upper surfaces of the two longitudinal beams, and the two upper ends of the lower ring beam are connected to the lower parts of the two longitudinal beams at positions corresponding to the upper ring beam.

[0006] Optionally, both the upper ring beam and the lower ring beam are box girder structures assembled and welded from plates.

[0007] Optionally, a reinforcing plate is welded inside the lower ring beam.

[0008] Optionally, a reinforcing rib is provided at the connection between the lower ring beam and the longitudinal beam.

[0009] Optionally, the upper end of the lower ring beam is used to weld to the side of the longitudinal beam, and the weld between the lower ring beam and the side of the longitudinal beam is set as a wavy line structure.

[0010] Optionally, the ring beam structure further includes a support platform, which is used to be welded to the upper end face of the lower ring beam and the upper end face of the longitudinal beam.

[0011] Optionally, a mounting plate is welded to the connection between the support platform and the lower ring beam.

[0012] Optionally, the lower end of the upper ring beam is connected to the upper end face of the support platform by bolt thread.

[0013] Optionally, the upper end face of the upper ring beam is provided with a lifting lug.

[0014] Compared with the prior art, the ring beam structure provided by this utility model has the following technical effects:

[0015] The ring beam structure provided by this utility model can be applied to and installed on the frame of a wide-body vehicle. By setting an inverted U-shaped upper ring beam and a U-shaped lower ring beam, and by setting two parallel longitudinal beams on the wide-body vehicle frame, the upper and lower ring beams, when installed at corresponding positions on the two longitudinal beams, form an approximately rectangular installation space. This space can be used to install the powertrain of the wide-body vehicle. Furthermore, by setting two symmetrical first rounded corner bends on the upper part of the upper ring beam and two symmetrical second rounded corner bends on the lower part of the lower ring beam, the rounded corner bend structure can... This design effectively transitions and transfers stress, preventing stress concentration issues that can easily occur in right-angle structures, thus improving the stability of the ring beam structure. Furthermore, by detachably connecting the upper ring beam to the longitudinal beams of the frame, the upper ring beam can be easily removed from the frame, facilitating the maintenance and repair of components such as the power system installed within the ring beam structure. Through the above structural design, not only is the structural strength and stability of the ring beam structure improved and its service life extended, but it also facilitates the maintenance and repair of internal components, such as the power system, thereby enhancing the convenience of maintenance and repair operations.

[0016] In addition, this utility model also provides a wide-body vehicle, including the above-mentioned ring beam structure.

[0017] Compared with the prior art, the wide-body vehicle provided by this utility model has the same technical effect as the aforementioned ring beam structure by setting a ring beam structure, and will not be described in detail here. Attached Figure Description

Therefore, it should not be construed as a limitation on the scope of protection of this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0027] To solve the above technical problems, such as Figure 1 and Figure 2 As shown, this utility model embodiment provides a ring beam structure, characterized in that it is used for the frame of a wide-body vehicle. The ring beam structure includes an upper ring beam 10 and a lower ring beam 20. The upper ring beam 10 has an inverted U-shaped structure, and two first rounded corner bending structures are symmetrically arranged on the upper part of the upper ring beam 10. The lower ring beam 20 has a U-shaped structure, and two second rounded corner bending structures are symmetrically arranged on the lower part of the lower ring beam 20. The frame includes two parallel longitudinal beams 01. The two lower ends of the upper ring beam 10 are respectively used to detachably connect to the upper surfaces of the two longitudinal beams 01. The two upper ends of the lower ring beam 20 are respectively used to connect to the lower part of the two longitudinal beams 01 at the positions corresponding to the upper ring beam 10.

[0028] It should be noted that in existing technologies, ring beam structures are generally made by directly welding steel plates to the vehicle frame, which can easily lead to stress concentration at right angles, resulting in instability such as weld cracking and deformation. In this embodiment, by setting rounded corners at the corresponding four corners of the upper ring beam 10 and the lower ring beam 20, stress concentration is avoided, allowing for effective stress transition and transfer, thereby improving the overall structural stability and strength. Preferably, the first and second rounded corner bending structures on the upper ring beam 10 and the lower ring beam 20, without affecting the installation of, for example, the powertrain of a wide-body vehicle, have their rounded corners maximized to further reduce stress concentration.

[0029] Specifically, the ring beam structure is installed on the frame of the wide-body vehicle, and the main body of the frame consists of two parallel longitudinal beams 01, such as... Figure 2 As shown, both the upper ring beam 10 and the lower ring beam 20 are symmetrical structures, which meet the overall symmetrical installation requirements of the wide-body vehicle and improve structural stability. The upper ring beam 10, the lower ring beam 20 and the two longitudinal beams 01 are connected to form a ring-shaped installation space for installing the power system of the wide-body vehicle. At the same time, the lower part of the lower ring beam 20 is also symmetrically provided with mounting seats 70. The mounting seats 70 can be used as the installation structure for components in the front axle system or front suspension system of the wide-body vehicle. The structural layout is more reasonable and reliable.

[0030] In this embodiment, the ring beam structure provided can be applied to and installed on the frame of a wide-body vehicle. By setting an inverted U-shaped upper ring beam 10 and a U-shaped lower ring beam 20, and by setting two parallel longitudinal beams 01 on the frame of the wide-body vehicle, after the upper ring beam 10 and the lower ring beam 20 are installed on the two longitudinal beams 01 at corresponding positions, an approximately rectangular installation space can be formed, which can be used to install the power system of the wide-body vehicle, etc. At the same time, by setting two symmetrical first rounded corner bends on the upper part of the upper ring beam 10 and two symmetrical second rounded corner bends on the lower part of the lower ring beam 20, the rounded corner bends... The structure effectively transitions and transmits stress, preventing stress concentration issues that can easily occur in right-angle structures, thus improving the stability of the ring beam structure. Furthermore, by detachably connecting the upper ring beam 10 to the longitudinal beam 01 of the frame, the upper ring beam 10 can be easily removed from the frame, facilitating the maintenance and repair of components such as the power system installed within the ring beam structure. Through the above structural design, not only is the structural strength and stability of the ring beam structure improved and its service life extended, but the maintenance and repair of internal components, such as the power system, are also facilitated, enhancing the convenience of maintenance and repair operations.

[0031] Optionally, such as Figure 1 and Figure 2 As shown, both the upper ring beam 10 and the lower ring beam 20 are box girder structures assembled and welded from plates.

[0032] For example, the lower ring beam 20 is a box beam structure with a rectangular or square cross section formed by welding an inner plate 21, two side plates 22 and an outer plate 23. The mounting base 70 is welded to the outer plate 23. Correspondingly, the structure and form of the upper ring beam 10 are similar to those of the lower ring beam 20. It is also a box beam structure with a rectangular or square cross section formed by welding plates. No specific limitation is made here.

[0033] In this embodiment, by setting both the upper ring beam 10 and the lower ring beam 20 as box girder structures made of welded plates, on the one hand, the box girder structure is more stable and reliable and can effectively bear bending moment or torque; on the other hand, its hollow structure can reduce the overall weight and save materials.

[0034] Optionally, such as Figure 1 and Figure 2 As shown, a reinforcing plate is welded inside the lower ring beam 20.

[0035] Specifically, multiple reinforcing plates are provided, which can be distributed within the lower ring beam 20 according to actual needs. Preferably, the reinforcing plates are welded to the inner plate 21, side plate 22 and outer plate 23 inside the lower ring beam 20, resulting in higher structural strength and a more stable and reliable structure.

[0036] In this embodiment, by welding a reinforcing plate inside the lower ring beam 20, the structural strength of the lower ring beam 20 can be further improved, making the lower ring beam 20 more resistant to bending and torsion, and further improving the stability of the overall structure.

[0037] Optionally, such as Figure 1 and Figure 2 As shown, a reinforcing rib plate 30 is provided at the connection between the lower ring beam 20 and the longitudinal beam 01.

[0038] Specifically, there are two sets of reinforcing ribs 30, with two reinforcing ribs 30 in each set. Each set of reinforcing ribs 30 is welded to the lower end face of the longitudinal beam 01 and the front side plate 22 of the lower ring beam 20, respectively. In other words, the reinforcing ribs 30 are welded to the lower end face of the longitudinal beam 01 and the front side plate 22 of the lower ring beam 20, respectively. A support plate is also welded between the two reinforcing ribs 30 in a set, which can further improve the strength and stability of the structure.

[0039] In this embodiment, by providing a reinforcing rib 30 at the connection between the lower ring beam 20 and the longitudinal beam 01, the strength and stability of the structure can be further improved, making the overall structure more robust and reliable, and also increasing the service life of the ring beam structure.

[0040] Optionally, such as Figure 1 and Figure 2 As shown, the upper end of the lower ring beam 20 is used to weld to the side of the longitudinal beam 01, and the weld between the lower ring beam 20 and the side of the longitudinal beam 01 is set as a wavy line structure 40.

[0041] Specifically, the two upper ends of the lower ring beam 20 are symmetrically provided with two L-shaped notch structures, that is, the upper ends of the lower ring beam 20 are covered and welded to the bottom and outer sides of the longitudinal beam 01, making the connection more stable and reliable, and further improving the structural strength.

[0042] In this embodiment, by welding the upper end of the lower ring beam 20 to the side of the longitudinal beam 01, the connection area is increased, making the connection more stable and reliable. At the same time, by setting the weld between the lower ring beam 20 and the side of the longitudinal beam 01 as a wavy line structure 40, on the one hand, the weld length is extended, improving the reliability of the connection; on the other hand, the wavy line structure 40 also prevents stress concentration that is prone to occur with straight welds, effectively avoiding weld cracking and other adverse conditions, further improving the stability of the ring beam structure.

[0043] Optionally, such as Figure 1 and Figure 2 As shown, the ring beam structure also includes a support platform 50, which is used to be welded to the upper end face of the lower ring beam 20 and the upper end face of the longitudinal beam 01.

[0044] Specifically, there are two support platforms 50, which are arranged symmetrically on the left and right. The support platforms 50 can be reserved with installation structures to provide installation and support structures for other components of the wide-body vehicle, making the structural layout more reasonable and reliable.

[0045] In this embodiment, by simultaneously welding a support platform 50 to the upper end face of the lower ring beam 20 and the upper end face of the longitudinal beam 01, the support platform 50 serves two purposes. First, it can act as an installation and load-bearing structure for other components of the wide-body vehicle, resulting in a more rational structural layout. Second, by welding the support platform 50 to both the lower ring beam 20 and the longitudinal beam 01, the connection strength between the lower ring beam 20 and the longitudinal beam 01 is further strengthened, thereby further improving the stability and reliability of the ring beam structure.

[0046] Optionally, such as Figure 1 and Figure 2 As shown, an mounting plate 60 is welded at the connection between the support platform 50 and the lower ring beam 20.

[0047] Specifically, there are two sets of mounting plates 60 arranged symmetrically on the left and right. Each set contains two mounting plates 60. A support plate can also be set between the two mounting plates 60 in each set to further strengthen the structure. At the same time, structures such as bushings can be set on the mounting plates 60, for example, as the articulation structure of the front suspension cylinder in the front suspension system of a wide-body vehicle, making the structural layout more reasonable.

[0048] In this embodiment, a mounting plate 60 is welded at the connection between the support platform 50 and the lower ring beam 20. That is, the mounting plate 60 is welded to the support platform 50 and the lower ring beam 20 respectively. On the one hand, the mounting plate 60 can serve as the mounting structure for other components on the wide-body vehicle, such as the front suspension cylinder of the front suspension system, making the structural layout more reasonable and reliable. On the other hand, the mounting plate 60 also plays the role of strengthening the rib support, further improving the structural strength.

[0049] Optionally, such as Figure 1 and Figure 2 As shown, the lower end of the upper ring beam 10 is connected to the upper end face of the support platform 50 by bolt thread.

[0050] Specifically, the lower end of the upper ring beam 10 can be laterally extended with a plate or connecting seat structure, and a threaded hole is vertically opened. Similarly, the support platform 50 is also vertically opened with a corresponding threaded hole at the corresponding position, which is threadedly connected with bolts. The structure is stable and reliable, and is easy to connect and disassemble.

[0051] In this embodiment, by connecting the lower end of the upper ring beam 10 to the upper end face of the support platform 50 with bolt threads, it is not only easy to assemble and produce, but also easy to disassemble, that is, easy to remove the upper ring beam 10, thereby improving the convenience of maintenance and repair of the power system of vehicles such as wide-body vehicles.

[0052] Optionally, such as Figure 1 and Figure 2 As shown, the upper end face of the upper ring beam 10 is provided with a lifting lug 11.

[0053] Specifically, there are two lifting lugs 11, which are symmetrically arranged on the left and right sides, making the lifting structure more stable and reliable.

[0054] In this embodiment, by providing a lifting lug 11 at the upper end of the upper ring beam 10, it is convenient to cooperate with other lifting mechanisms, that is, to facilitate the removal of the upper ring beam 10 from the frame, thereby further improving the convenience and efficiency of maintenance and repair operations.

[0055] In addition, another embodiment of this utility model provides a wide-body vehicle, including the above-mentioned ring beam structure.

[0056] For example, the wide-body vehicle is a mining heavy-duty off-highway wide-body dump truck, including a frame, the frame including two parallel longitudinal beams 01.

[0057] In this embodiment, the wide-body vehicle provided by this embodiment, by setting the above-mentioned ring beam structure, has roughly the same technical effect as the above-mentioned ring beam structure, and will not be described again here.

[0058] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
