Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a cargo box structure and a wide-body dump truck equipped with it. Background Technology

[0002] Wide-body dump trucks are commonly used in mining or engineering construction. The cargo box of a typical wide-body dump truck is usually composed of a front panel, side panels, bottom panel, and rear panel. The connection between the panels is usually a vertical connection, that is, the side panels and bottom panels are joined vertically and fixed by welding or bolts to form a connection structure.

[0003] In actual use, when the cargo load in the container is large, the cargo will impact the container body, especially at the connection between the side panels and the bottom panel. When the cargo weight is large or the transportation conditions are poor, the stress at the connection between the side panels and the bottom panel will increase, which can easily lead to problems such as weld cracking, bolt loosening or plate deformation, which is not conducive to improving the service quality of the container body. Utility Model Content

[0017] Furthermore, a third reinforcing beam is provided on the side where the side plate is connected to the tail plate. The top of the third reinforcing beam is connected to the top of the side plate, and the bottom of the third reinforcing beam is connected to the first longitudinal beam.

[0018] Compared with related technologies, this application has the following advantages:

[0019] (1) The cargo box structure described in this application, by making the bottom of the side plate arc-shaped and connecting it to the first longitudinal beams on both sides of the bottom plate, facilitates the transfer of the force on the side of the cargo box to the bottom plate.

[0026] (8) By setting the second reinforcing rib, the connection strength between the first crossbeam and the first longitudinal beam and the second longitudinal beam is improved, which facilitates the design and implementation.

[0027] (9) By making the first crossbeam a plurality of spaced-apart ones along the length of the bottom plate, it helps to establish multiple force transmission paths on the bottom plate, which facilitates better distribution of the force on the two side plates, thereby improving the structural strength of the cargo box structure and making the design and implementation easier.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" 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 or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0048] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0049] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0050] The first aspect of this application provides a cargo box structure for use on a wide-body dump truck, mainly for loading goods. The cargo box structure of this embodiment, with its innovative structural design, can ensure the structural strength of the cargo box during use, reduce the probability of damage to the cargo box, and thus help reduce the maintenance cost of the cargo box.

[0051] In related technologies, wide-body dump trucks are often used for heavy-load applications, thus requiring the cargo box to have high structural strength to ensure the transportation of goods. The cargo box of a common wide-body dump truck is usually composed of a front panel, side panels, bottom panel, and rear panel. The connection between the panels is usually a vertical connection, that is, the side panels and bottom panel are butt-jointed vertically and fixed by welding or bolts to form a connection structure.

[0052] In actual use, when the cargo load inside the container is large, the weight of the cargo itself and the bumps caused by poor road conditions will cause the cargo to impact the container body inside the container. In particular, the connection between the side panels and the bottom panel will generate greater stress, which can easily lead to problems such as weld cracking, bolt loosening or plate deformation at the connection points, which is not conducive to improving the service quality of the container body.

[0053] In view of this, in order to overcome the shortcomings of the related technology, the cargo box structure of this embodiment combines... Figures 1 to 7 As shown, the overall design includes a base plate 1 and side plates 2.

[0054] The side plate 2 is located on both sides of the base plate 1 along the width direction. The base plate 1 has first longitudinal beams 5 on both sides, and the bottom of the side plate 2 is connected to the first longitudinal beams 5. The bottom of the side plate 2 is arc-shaped, and the side plate 2 is provided with a first reinforcing beam 6. The bottom of the first reinforcing beam 6 is connected to the first longitudinal beam 5 on the corresponding side, and the top of the first reinforcing beam 6 extends towards the top of the side plate 2.

[0055] A first crossbeam 7 is provided between the first longitudinal beams 5 on both sides of the base plate 1, and the connection between the first crossbeam 7 and the first longitudinal beam 5 is provided corresponding to the connection between the first reinforcing beam 6 and the first longitudinal beam 5.

[0056] Therefore, by making the bottom of the side plate 2 arc-shaped and connecting it to the first longitudinal beams 5 on both sides of the bottom plate 1, it is convenient to transfer the force on the side of the cargo box to the bottom plate 1. Furthermore, by setting the first crossbeam 7 between the first longitudinal beams 5 on both sides, the force on the side plates 2 on both sides can be transferred to the bottom plate 1 and offset, thereby helping to improve the structural strength of the side plate 2 and the bottom plate 1, and improving the structural strength of the cargo box structure, which in turn helps to improve the quality of use of the cargo box.

[0057] Based on the above overall introduction, specifically, as an exemplary structural form, the cargo box structure of this embodiment is still composed of... Figures 1 to 2 As shown, in addition to the base plate 1 and the side plate 2, it generally also includes the front plate 3 and the tail plate 4.

[0058] The front panel 3 is connected to the bottom plate 1 near the front of the vehicle to form the front of the cargo box. Alternatively, on some mining dump trucks, the top of the front panel 3 extends towards the front of the vehicle and covers the cab of the dump truck to provide protection for the cab.

[0059] The connection method between the front panel 3 and the bottom panel 1 can be referenced from the existing connection method between the front panel 3 and the bottom panel 1 of the cargo box (such as plug welding, etc.), and will not be described in detail here.

[0060] Furthermore, the tailgate 4 is located near the rear of the vehicle on the floor 1 and is typically connected to the two side panels 2 via a flipping structure (such as a hinge). During unloading, the tailgate 4 can be flipped open to allow the cargo to tip over. Simultaneously, the connection between the tailgate 4 and the floor 1 usually has an openable locking structure to ensure that the tailgate 4 is restrained on the floor 1 during transportation, preventing cargo spillage. The connection methods between the tailgate 4 and the side panels 2, and between the tailgate 4 and the floor 1, can be referenced from the existing cargo box structures and will not be elaborated further here.

[0061] It is worth mentioning that the structures of the front panel 3 and the rear panel 4, in addition to adopting the structures described above, can be derived from the relevant structures in existing cargo box bodies, and will not be elaborated further here.

[0062] Continue to combine Figures 1 to 7 As shown, in some exemplary embodiments, for example, the side panel 2 in this embodiment may have a second reinforcing beam 8 located near the rear of the vehicle.

[0063] The bottom of the second reinforcing beam 8 is connected to the first longitudinal beam 5 on the corresponding side, and the top of the second reinforcing beam 8 is connected to the top of the side plate 2. The connection points of the second reinforcing beams 8 on both sides and the first longitudinal beams 5 on the corresponding side are respectively set.

[0064] It should be noted that the body of a common dump truck is usually raised by a lifting mechanism to tilt the body so that the goods can be dumped out from the rear. It can be understood that by setting the second reinforcing beam 8, the structural strength of the side plate 2 near the rear of the vehicle is improved, which is beneficial to the use of the cargo box during the self-unloading operation and helps the design and implementation.

[0065] In a specific implementation, the side plate 2 may, for example, be provided with a side beam 9 to improve the structural strength of the side plate 2. The side beam 9 extends along the length of the side plate 2. The second reinforcing beam 8 may include an upper beam body located above the side beam 9 and a lower beam body located below the side beam 9. The top of the upper beam body is connected to the top of the side plate 2, and the bottom of the upper beam body is connected to the upper side of the side beam 9. The top of the lower beam body is connected to the lower side of the side beam 9, and the bottom of the lower beam body is connected to the side plate 2.

[0066] Continue to combine Figures 1 to 7 As shown, in some exemplary embodiments, the cargo box structure still includes side panels 2 and bottom panels 1 as an example. This embodiment may, for example, make the cargo box structure also include front panels 3 and rear panels 4.

[0067] The front panel 3, side panel 2, tail panel 4 and bottom panel 1 form a storage space for placing goods. The storage space is provided with a first panel 10, a second panel 11 and a third panel 12. The first panel 10 is connected between the vertical sections of the front panel 3 and the side panel 2, the second panel 11 is connected between the arc-shaped sections of the front panel 3 and the side panel 2, and the third panel 12 is connected between the front panel 3 and the bottom panel 1.

[0068] It is understandable that by setting the first plate 10, the second plate 11 and the third plate 12 in the storage space, it is beneficial to protect the connection position between the front plate 3 and the bottom plate 1 and the side plate 2, improve the connection strength between the front plate 3 and the bottom plate 1 and the side plate 2, and thus help to improve the structural strength of the cargo box structure.

[0069] In specific implementation, the top of the first plate 10 is bent and connected to the front plate 3 and the side plate 2. The bottom of the first plate 10 is connected to the top of the second plate 11. The bottom of the second plate 11 is connected to the third plate 12. After the first plate 10, the second plate 11, and the third plate 12 are connected, they are fastened in the storage space and cooperate with the front plate 3, the side plate 2, and the bottom plate 1 to form a load-bearing structure. When goods are loaded into the box, the above load-bearing structure can protect the connection between the front plate 3, the side plate 2, and the tail plate 4, and can disperse part of the weight and impact force of the goods, so as to better improve the structural strength of the cargo box.

[0070] Continue to combine Figures 1 to 7 As shown, in some exemplary embodiments, taking the cargo box structure including side plate 2, bottom plate 1 and tail plate 4 as an example, this embodiment may provide a third reinforcing beam 13 on the side where the side plate 2 is connected to the tail plate 4. The top of the third reinforcing beam 13 is connected to the top of the side plate 2, and the bottom of the third reinforcing beam 13 is connected to the first longitudinal beam 5.

[0071] Understandably, the installation of the third reinforcing beam 13 enhances the structural strength of the rear of the side plate 2, facilitates the self-unloading operation of the cargo box, and is beneficial to the design and implementation.

[0072] In practical implementation, the top of the third reinforcing beam 13 is equipped with a hinge, and the top of the tail plate 4 is flipped onto the third reinforcing beam 13 via the hinge. The connection between the tail plate 4 and the third reinforcing beam 13 can be either a hinge or, in other words, a connection between the tail plate 4 and the side plate 2 of the existing box body, which will not be described in detail here.

[0073] Continue to combine Figures 1 to 7 As shown, in some exemplary embodiments, taking the side plate 2 with a first reinforcing beam 6 as an example, this embodiment may, for example, have a skirt plate 14 on the side plate 2, with the top of the first reinforcing beam 6 connected to the skirt plate 14, and the skirt plate 14 extending outward and downward from the side plate 2.

[0074] Understandably, the skirt 14 further transfers the force on the side plate 2 downwards, and together with the first reinforcing beam 6, it further enhances the structural strength of the side plate 2, which is conducive to design implementation.

[0075] In practice, one end of the skirt plate 14 is connected to the side plate 2, and the other end extends diagonally downward from the side plate 2. The top of the first reinforcing beam 6 is connected to the skirt plate 14, and the skirt plate 14 forms a cover over the top of the first reinforcing beam 6.

[0076] Continue to combine Figures 1 to 7 As shown, in some exemplary embodiments, taking the side plate 2 with a skirt plate 14 as an example, this embodiment may, for example, provide a first reinforcing rib 15 between the skirt plate 14 and the first reinforcing beam 6.

[0077] The first reinforcing rib 15 includes a first stiffening plate 1501 and a second stiffening plate 1502 that are connected to each other. The first stiffening plate 1501 is connected between the skirt plate 14 and the first reinforcing beam 6, and the second stiffening plate 1502 extends from the first stiffening plate 1501 toward the connection between the skirt plate 14 and the first reinforcing beam 6.

[0078] It is understandable that by setting the first reinforcing rib 15, a new force transmission channel is established between the skirt plate 14 and the first reinforcing beam 6, which facilitates the skirt plate 14 to transmit the force of the side plate 2 downward, and improves the connection strength between the side plate 2 and the skirt plate 14, which is beneficial to the design and implementation.

[0079] In specific implementation, the first stiffener 1501 can be rectangular for example, and the second stiffener 1502 can be triangular for example. The second stiffener 1502 can also be provided with a hollow, so as to reduce the weight of the second stiffener 1502 and facilitate assembly.

[0080] It should be noted that by setting the first reinforcing rib 15, a new force transmission channel is constructed between the skirt plate 14 and the first reinforcing beam 6. At this time, after the skirt plate 14 receives the force distributed from the side plate 2, it can transmit the force received to the first reinforcing beam 6 through the first reinforcing rib 15, and then transmit the force to the bottom plate 1 through the first reinforcing beam 6, and cancel out the force on the other side plate 2.

[0081] Continue to combine Figures 1 to 7 As shown, in some exemplary embodiments, for the base plate 1 of this embodiment, the base plate 1 may be provided with a second longitudinal beam 16, the second longitudinal beam 16 being arranged at intervals between the first longitudinal beams 5 located on both sides, and the second longitudinal beam 16 extending along the length direction of the base plate 1.

[0082] The first crossbeam 7 includes a first segment 701 located between the first longitudinal beam 5 and the second longitudinal beam 16, and a second segment 702 located between two adjacent second longitudinal beams 16.

[0083] It is understandable that by setting the second longitudinal beam 16, the structural strength of the base plate 1 is improved, and the segmented setting of the first cross beam 7 facilitates the transfer of the force of the side plate 2 to the first longitudinal beam 5 and the second longitudinal beam 16 for dispersion, which helps to improve the structural strength of the base plate 1, facilitates processing and manufacturing, and helps with design implementation.

[0084] In specific implementation, in order to better improve the structural strength of the base plate 1, a central longitudinal beam 17 is also provided in the middle of the base plate 1. The central longitudinal beam 17 extends from the middle of the base plate 1 along the length direction of the base plate 1. Through the setting of the central longitudinal beam 17, the second section 702 located between the two second longitudinal beams 16 is further divided into two parts, so as to facilitate the distribution of the force on both sides to other parts through the connection of the central longitudinal beam 17.

[0085] Continue to combine Figures 1 to 7 As shown, in some exemplary embodiments, taking the second longitudinal beam 16 on the base plate 1 as an example, this embodiment may provide a second reinforcing rib 18 at the connection between the first segment 701 and the first longitudinal beam 5, and at the connection between the first segment 701 and the second longitudinal beam 16.

[0086] Understandably, the addition of the second reinforcing rib 18 improves the connection strength between the first crossbeam 7 and the first longitudinal beam 5 and the second longitudinal beam 16, facilitating design and implementation.

[0087] In specific implementation, the second reinforcing rib 18 can be formed by combining multiple triangular plates and rectangular plates. The combination of multiple triangular plates and rectangular plates forms a reinforcing structure and is fastened to the connection between the first horizontal beam 7 and the first longitudinal beam 5, as well as the connection between the first horizontal beam 7 and the second longitudinal beam 16. This not only protects the connection but also disperses the force, thereby helping to improve the structural strength of the connection.

[0088] Continue to combine Figures 1 to 7 As shown, in some exemplary embodiments, taking the second longitudinal beam 16 on the base plate 1 as an example, this embodiment may, for example, make the first crossbeam 7 a plurality of beams spaced apart along the length of the base plate 1.

[0089] Among them, a second crossbeam 19 is provided between two adjacent second sections 702 located in the middle and rear part of the base plate 1, and the two ends of the second crossbeam 19 are respectively connected to the second longitudinal beam 16 on the corresponding side.

[0090] It is understandable that by arranging multiple first crossbeams 7 at intervals along the length of the base plate 1, it helps to establish multiple force transmission paths on the base plate 1, which facilitates better distribution of the force on the two side plates 2, thereby improving the structural strength of the cargo box structure and making the design and implementation easier.

[0091] In practical implementation, the second crossbeam 19 is located between two connected second longitudinal beams 16, which can establish an additional force transmission path between two adjacent second longitudinal beams 16, so that the force transmitted to the second longitudinal beam 16 is further dispersed and transmitted to the second longitudinal beam 16 on the other side through the second crossbeam 19, thereby canceling it out.

[0092] It is worth noting that, regarding this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still... Figures 1 to 7 As shown, it generally includes a base plate 1, side plates 2, front plate 3, and tail plate 4.

[0093] The base plate 1 has first longitudinal beams 5 on both sides, and side plates 2 are arranged along the width direction of the base plate 1 on both sides, with the bottom of the side plates 2 connected to the first longitudinal beams 5. The bottom of the side plates 2 is arc-shaped, and a first reinforcing beam 6 is provided on the side plates 2. The bottom of the first reinforcing beam 6 is connected to the first side beam on the corresponding side, and the top of the first reinforcing beam 6 extends towards the top of the side plates 2. A first transverse beam 7 is provided between the two first longitudinal beams 5, and the connection between the first transverse beam 7 and the first longitudinal beam 5 corresponds to the connection between the first reinforcing beam 6 and the first longitudinal beam 5.

[0094] The front panel 3 is connected to the front of the bottom panel 1 and has a protective edge covering the cab. The rear panel 4 is hinged and flipped between the two side panels 2, and a locking structure is provided at the connection between the rear panel 4 and the bottom panel 1. Within the storage space formed by the front panel 3, side panels 2, rear panel 4 and bottom panel 1, there are a first panel 10, a second panel 11 and a third panel 12. The first panel 10 is connected between the vertical sections of the front panel 3 and the side panels 2, the second panel 11 is connected between the arc-shaped sections of the front panel 3 and the side panels 2, and the third panel 12 is connected between the front panel 3 and the bottom panel 1.

[0099] In the preferred embodiment of the above cargo box structure, the specific setting and arrangement of the bottom plate 1, side plate 2, first reinforcing beam 6 and second reinforcing beam 8, etc., can still be referred to the description in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the bottom plate 1, side plate 2, first reinforcing beam 6 and second reinforcing beam 8, etc., can also be referred to the description in the above exemplary embodiments.

[0100] The cargo box structure of this embodiment adopts the above design. By making the bottom of the side plate 2 arc-shaped and connecting it to the first longitudinal beams 5 on both sides of the bottom plate 1, it is convenient to transfer the force on the side of the cargo box to the bottom plate 1. Furthermore, by setting the first crossbeam 7 between the first longitudinal beams 5 on both sides, the force on the side plates 2 on both sides can be transferred to the bottom plate 1 and offset, thereby helping to improve the structural strength of the side plates 2 and the bottom plate 1, and improving the structural strength of the cargo box structure, which in turn helps to improve the quality of use of the cargo box.

[0101] An embodiment of the second aspect of this application provides a wide-body dump truck, which has a cargo box structure as described above.

[0102] In the wide-body dump truck of this embodiment, the aforementioned cargo box structure has storage space and is typically mounted on the chassis of the wide-body dump truck. The connection method between the cargo box structure and the chassis of the wide-body dump truck can be referenced from the connection method of existing wide-body dump trucks, and will not be described in detail here.

[0103] In addition, still based on Figures 1 to 3 Taking the embodiment shown as an example, in a specific application, when the cargo exerts a force on the side plate 2, the force on the side plate 2 can be transmitted to the bottom plate 1 and cancel out the force on the other side plate 2.

[0104] In this embodiment of the wide-body dump truck, the bottom of the side plate 2 is arranged in an arc shape and connected to the first longitudinal beams 5 on both sides of the bottom plate 1. This facilitates the transfer of the force on the side of the cargo box to the bottom plate 1. Furthermore, the first crossbeam 7 located between the first longitudinal beams 5 on both sides can transfer the force on the side plates 2 to the bottom plate 1 and offset it. This helps to improve the structural strength of the side plates 2 and the bottom plate 1, as well as the structural strength of the cargo box structure, thereby improving the quality of use of the cargo box and thus enhancing the overall quality of use of the wide-body dump truck.

[0105] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
