Description

Technical Field

[0001] This invention relates to the field of mining transportation technology, specifically to a cargo box and vehicle. Background Technology

[0002] Currently, cargo boxes used for transporting materials are mostly rectangular or polygonal in shape, meaning that the side panels of the cargo box are vertically mounted on the bottom plate, or the side panels are bent outward from the position where they are connected to the bottom plate to form a polygon.

[0003] For example, the cargo boxes of mining dump trucks are mostly rectangular in shape. By loading materials into the cargo boxes, they can be used for large-scale transportation in large mines, large-scale water conservancy projects, and the energy sector.

[0004] However, in the case of cargo boxes of the above shape, during the loading process, the material will directly impact the connection between the side panels and the bottom panel and the bending points of the side panels. Since the connection between the side panels and the bottom panel and the bending points of the side panels are stress concentration areas, long-term material impact can lead to deformation and cracking. Summary of the Invention

[0005] This invention provides a cargo box and vehicle to solve the problem of cargo boxes being prone to deformation and cracking in the prior art.

[0007] The upper part of the side plate is a straight plate, and the lower part of the side plate is an arc-shaped plate. The two side plates are respectively connected to the two sides of the bottom plate through the arc-shaped plate.

[0008] The outer side of the arc-shaped plate has multiple outer curved plates along its length, and the shape of the outer curved plates is adapted to the shape of the arc-shaped plate.

[0010] According to the cargo box provided by the present invention, a positioning structure is provided between the side edge of the front panel and the side panel and / or between the bottom edge of the front panel and the bottom plate.

[0011] According to the cargo box provided by the present invention, the positioning structure includes a positioning protrusion and a positioning hole, one of the positioning protrusion and the positioning hole is provided on the front plate, and the other is provided on the side plate and / or the bottom plate.

[0012] According to the cargo box provided by the present invention, the bottom of the base plate is provided with a mesh first reinforcing structure.

[0013] According to the cargo box provided by the present invention, the reinforcing structure includes multiple third crossbeams and multiple first longitudinal beams. The third crossbeams are provided with insertion holes, and the first longitudinal beams are inserted into the insertion holes. The multiple third crossbeams and the multiple first longitudinal beams are interwoven to form a mesh.

[0014] According to the cargo box provided by the present invention, a shock-absorbing adjustment structure is provided between the third crossbeam and the vehicle frame, and the shock-absorbing adjustment structure is used to buffer and protect the vehicle frame during the loading of materials.

[0015] According to the cargo box provided by the present invention, the shock absorption adjustment structure includes:

[0016] A shock-absorbing pad, wherein the shock-absorbing pad is connected to the third crossbeam by bolts;

[0017] An adjusting plate is disposed between the shock-absorbing pad and the third crossbeam, and the adjusting plate is used to adjust the distance between the shock-absorbing pad and the third crossbeam.

[0018] According to the cargo box provided by the present invention, the top of the rear panel is hinged to the two side panels, and an inclined chain is provided between the bottom of the rear panel and the frame, the chain being used to lock the rear panel and the frame.

[0019] A second aspect of the invention provides a vehicle including the cargo box as described above.

[0020] One of the above technical solutions has the following advantages: The cargo box provided by this technical solution is a hollow box structure composed of a front panel, a rear panel, side panels, and a bottom panel. The lower part of the side panel is an arc-shaped plate. Each side panel is connected to both sides of the bottom panel through the arc-shaped plate. Multiple outward curved plates are provided along the length direction on the outer side of the arc-shaped plate. The shape of the outward curved plates is adapted to the shape of the arc-shaped plate. By setting the lower part of the side panel as an arc-shaped plate structure, the stress on the side panel of the cargo box can be effectively improved. During the loading process, when the material impacts the arc of the arc-shaped plate, the arc will evenly distribute the force, making the side panel uniformly stressed.

[0021] Furthermore, multiple outer bending plates are placed between the first and second crossbeams, which enhances the resistance to deformation. The outer bending plates are also overlapped between the first and second crossbeams, resulting in greater stability. Half of the width of the second crossbeam is covered by the outer bending plates, which can reduce the stress on the weld seams in the lower part of the side plate.

[0022] Furthermore, positioning structures are provided between the sides of the front panel and between the bottom edge of the front panel and the bottom plate. Alternatively, positioning structures can be selectively provided between the sides of the front panel and between the bottom edge of the front panel and the bottom plate. When welding the front panel to the side panel or the bottom plate, the positioning structures are used for pre-fixation before welding, which can reduce the stress at the weld and improve the overall strength of the cargo box.

[0023] Furthermore, the vehicle provided by the present invention also possesses the various advantages described above due to having a cargo box as described above. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0048] Currently, cargo boxes used for transporting materials are mostly rectangular or polygonal in shape, meaning that the side panels of the cargo box are vertically mounted on the bottom plate, or the side panels are bent outward from the position where they are connected to the bottom plate to form a polygon.

[0049] For example, the cargo boxes of mining dump trucks are mostly rectangular in shape. By loading materials into the cargo boxes, they can be used for large-scale transportation in large mines, large-scale water conservancy projects, and the energy sector.

[0050] However, in the case of cargo boxes of the above shape, during the loading process, the material will directly impact the connection between the side panels and the bottom panel and the bending points of the side panels. Since the connection between the side panels and the bottom panel and the bending points of the side panels are stress concentration areas, long-term material impact can lead to deformation and cracking.

[0051] In one embodiment of the present invention, by setting the lower part of the side plate as an arc-shaped plate structure, the stress on the side plate of the cargo box can be effectively improved. During the loading process, when the material impacts the arc of the arc plate, the arc will evenly distribute the force, making the side plate uniformly stressed. At the same time, the arc-shaped plate structure between the side plate and the bottom plate can prevent material from sticking, improve the unloading speed, and increase work efficiency. The outer curved plate is welded to the outside of the arc plate, and the shape of the outer curved plate is adapted to the shape of the arc plate, so that it can fit tightly with the arc plate and improve the strength of the side plate.

[0052] The following is combined with Figures 1 to 9 The present invention describes the cargo box and vehicle.

[0053] like Figure 1 and Figure 2 As shown, in a first aspect, one embodiment of the present invention provides a cargo box, which is a hollow box structure composed of a front panel 1, a rear panel 2, a side panel 3 and a bottom panel 4. The cargo box is mounted on a vehicle frame 5 and can be flipped relative to the vehicle frame 5 to complete the loading and unloading of materials.

[0054] The upper part of the side plate 3 is a straight plate 31, and the lower part of the side plate 3 is an arc-shaped plate 32. The two side plates are respectively located on both sides of the bottom plate 4. Each side plate 3 is connected to both sides of the bottom plate 4 through the arc-shaped plate 32. Multiple outer curved plates 33 are provided on the outer side of the arc-shaped plate 32 along the length direction. The shape of the outer curved plates 33 is adapted to the shape of the arc-shaped plate 32.

[0055] Specifically, the cargo box consists of a front panel 1, a rear panel 2, side panels 3, and a bottom panel 4. Two side panels are connected to both sides of the bottom panel 4. The upper part of each side panel 3 is a straight plate 31, and the lower part is an arc-shaped plate 32. The arc-shaped plate 32 is formed by bending the lower part of the side panel 3 15 times to create an arc shape, which is then welded to the bottom panel 4. The arc-shaped plate 32 structure of the lower part of the side panel 3 effectively improves the stress distribution on the side panel 3. During loading, when materials impact the arc of the arc-shaped plate 32, the force is evenly distributed, resulting in uniform stress on the side panel 3. Simultaneously, the arc-shaped plate 32 structure between the side panel 3 and the bottom panel 4 prevents materials from sticking together, increases unloading speed, and improves work efficiency. Since the lower part of the side panel 3 needs to be bent to form an arc-shaped panel 32 structure, the thickness of the side panel 3 is less than that of the bottom panel 4. Furthermore, for cargo box structures with equal width, the lower part of the side panel 3 is set as an arc-shaped panel 32 structure, replacing part of the bottom panel 4 with an arc, which reduces the weight of the cargo box and lowers material costs.

[0056] In order to further improve the strength of the arc-shaped plate 32 structure, in this embodiment, multiple outer curved plates 33 are provided on the outer side of the arc-shaped plate 32 along the length direction. The outer curved plates 33 are welded to the outer side of the arc-shaped plate 32, and the shape of the outer curved plates 33 is adapted to the shape of the arc-shaped plate 32, so that they can fit tightly with the arc-shaped plate 32, thereby improving the strength of the side plate 3.

[0057] In one embodiment of the present invention, by setting the lower part of the side plate 3 as an arc-shaped plate portion 32 structure, the stress on the side plate 3 of the cargo box can be effectively improved. During the loading process, when the material impacts the arc of the arc portion 32, the arc will evenly distribute the force, making the side plate 3 uniformly stressed. At the same time, the transition between the side plate 3 and the bottom plate 4 using the arc portion 32 structure can prevent material adhesion, improve unloading speed, and increase work efficiency. The outer curved plate 33 is welded to the outer side of the arc portion 32, and the shape of the outer curved plate 33 is adapted to the shape of the arc portion 32, so that it can fit tightly with the arc portion 32, improving the strength of the side plate 3. Furthermore, multiple first reinforcing ribs are also provided between the outer curved plate 33 and the arc portion 32.

[0058] Continue as Figure 2As shown, in some embodiments of the present invention, a first crossbeam 34 is provided on the outer side of the connection between the straight plate portion 31 and the arc-shaped plate portion 32, and a second crossbeam 35 is provided on the outer side of the connection between the arc-shaped plate portion 32 and the bottom plate 4. Multiple outer curved plates 33 are provided between the first crossbeam 34 and the second crossbeam 35, and half of the width of the second crossbeam 35 is covered by the outer curved plates 33. The lengths of the first crossbeam 34 and the second crossbeam 35 are the same as the length of the side plate 3. Compared with the existing broken beam structure, the structure of the first crossbeam 34 and the second crossbeam 35 has stronger resistance to deformation, no weld defects, and the outer curved plates 33 overlap between the first crossbeam 34 and the second crossbeam 35, resulting in stronger stability. When the side plate 3 is welded to the bottom plate 4, it is welded to the bottom plate 4 through the second crossbeam 35. In order to reduce the stress on the lower part of the weld of the side plate 3 and prevent the stress from concentrating at the weld, the outer bending plate 33 is overlapped on the second crossbeam 35, and half of the width of the second crossbeam 35 is covered by the outer bending plate 33, which can reduce the stress on the lower part of the weld of the side plate 3.

[0059] When welding the front plate 1 to the side plate 3 and the bottom plate 4, they are all manually held and fixed. The welding process involves welding the sides of the front plate 1 one by one. This method of welding one by one can easily cause stress at the weld joints. To solve this problem, such as... Figure 3 As shown, in some embodiments of the present invention, positioning structures are provided between the side edge of the front plate 1 and the side plate 3, and between the bottom edge of the front plate 1 and the bottom plate 4. Alternatively, positioning structures can be selectively provided at these two locations: between the side edge of the front plate 1 and the side plate 3, and between the bottom edge of the front plate 1 and the bottom plate 4. When welding the front plate 1 to the side plate 3 or the bottom plate 4, pre-fixing is performed using the positioning structures before welding, which can reduce the stress at the weld and improve the overall strength of the cargo box.

[0060] The positioning structure can be configured as a positioning pin and a positioning groove, or as a positioning protrusion 11 and a positioning hole. Specifically, the positioning structure includes a positioning protrusion 11 and a positioning hole. The positioning protrusion 11 is located on the front plate 1, and the positioning hole is located on the side plate 3 and the bottom plate 4, or the positioning hole can be selectively located on the side plate 3 and the bottom plate 4. The positioning protrusion 11 and the positioning hole are first inserted and then welded, which can reduce the stress at the weld and improve the overall strength of the cargo box.

[0061] like Figure 4 As shown, in some embodiments of the present invention, the bottom of the base plate 4 is provided with a mesh-like first reinforcing structure. The first reinforcing structure is formed by welding reinforcing ribs into a crisscrossing mesh, which can improve the strength of the base plate 4.

[0062] Specifically, the reinforced structure includes multiple third crossbeams 41 and multiple first longitudinal beams 42. The third crossbeams 41 are provided with insertion holes 43, and the first longitudinal beams 42 are inserted into the insertion holes 43. The multiple third crossbeams 41 and the first longitudinal beams 42 are interwoven to form a mesh, which improves the strength of the base plate 4. The strength at the intersection point is improved, which can reduce the stress on the weld and improve the service life.

[0063] The bottom plate 4, the third crossbeam 41, and the first longitudinal beam 42 are evenly provided with perforated structures. The heat of the engine on the frame 5 can be used to heat the perforated structures, so that the bottom plate 4 of the cargo box is heated evenly and the materials inside the cargo box can be heated. In winter, this prevents materials with high moisture content from sticking to the bottom plate 4 and making them impossible to unload.

[0064] Furthermore, a shock-absorbing adjustment structure 6 is provided between the third crossbeam 41 and the frame 5. The shock-absorbing adjustment structure 6 is used to buffer and protect the frame 5 during the loading process, preventing the impact of loading materials on the cargo box and causing wear to the upper surface of the frame 5. The shock-absorbing adjustment structure 6 can be equipped with a spring and rubber pad structure to buffer and protect the frame 5 and improve the service life of the frame 5.

[0065] like Figure 5 As shown, in some other embodiments, the shock absorption adjustment structure 6 includes a shock absorption pad 61 and an adjusting plate 62. The shock absorption pad 61 is connected to the third crossbeam 41 by bolts. The adjusting plate 62 is located between the shock absorption pad 61 and the third crossbeam 41. The adjusting plate 62 is used to adjust the distance between the shock absorption pad 61 and the third crossbeam 41, and to adjust the fit between the shock absorption pad 61 and the frame 5 to ensure uniform force distribution.

[0066] The cargo box is mounted on the frame 5 and can be flipped relative to the frame 5. Therefore, a lifting seat 7 is provided on the side of the bottom plate 4 near the front plate 1. Two lifting seats 7 are symmetrically arranged to form a double lifting seat structure, which, together with the double lifting cylinder structure of the whole machine, provides power for the cargo box to flip. The double lifting seat structure, together with the double lifting cylinder structure, results in a short lifting time, more stable lifting, and less cylinder dislodgement.

[0067] A tilting seat 8 is provided on the side of the bottom plate 4 near the rear plate 2. There are two tilting seats 8, which are set in correspondence with two lifting seats 7. The cargo box is hinged to the frame 5 through the tilting seat on the bottom plate 4. With the help of the double lifting cylinder structure, the cargo box is tilted relative to the frame 5.

[0068] like Figure 6 and Figure 7As shown, the tilting seat 8 consists of two upright plates 81 on both sides and a connecting plate 82 in the middle. The upright plates 81 have rectangular connecting holes 83 and cutouts 84 facing the base plate 4. These holes and cutouts are used to pass through the first longitudinal beam 42 on the base plate 4, forming an interlaced structure with the first longitudinal beam 42 to strengthen the connection with the base plate 4. The upright plates 81 have pin holes 85 and two limiting seats 86. A pin shaft 87 is inserted into the pin hole 85, and the tilting seat 8 is hinged to the frame 5 via the pin shaft 87. A limiting plate 88 is provided on one side of the pin shaft 87. After the pin shaft 87 is inserted into the pin hole 85, the limiting plate 88 on the pin shaft 87 connects to the limiting seat 86 on the upright plate 81. The limiting seat 86 and the limiting plate 88 limit the pin shaft 87, preventing it from rotating relative to the tilting seat 8. The pin shaft 87 can only rotate relative to the frame 5, reducing wear on the tilting seat 8 and further improving the service life of the cargo box. The cargo box and the frame 5 are hinged together by a flip seat 8, which facilitates cargo box installation and saves labor.

[0069] like Figure 8 As shown, in some embodiments of the present invention, the rear plate 2 is provided with a second reinforcing structure, which is formed by welding reinforcing ribs into a crisscross mesh, thereby improving the strength of the rear plate 2.

[0070] Specifically, the second reinforcing structure includes a fourth crossbeam 21 and multiple second longitudinal beams 22. The fourth crossbeam 21 is located in the middle of the rear plate 2. The fourth crossbeam 21 and the multiple second longitudinal beams 22 are connected in a continuous splicing manner, forming a mesh that improves the strength of the rear plate 2. The increased strength at the intersection points reduces the stress on the welds, preventing weld breakage due to material impact and extending service life. Reinforcing plates 23 are provided on both sides of the fourth crossbeam 21 to reduce the stress on the welds on both sides of the fourth crossbeam 21.

[0071] At the bottom of the rear plate 2, there is a fifth crossbeam 24. The outer side of the fifth crossbeam 24 is covered by a protective plate 25. The protective plate 25 has an L-shaped structure, which can improve the rigidity of the fifth crossbeam 24 and prevent deformation. Reinforcing ribs are set on the inner side of the fifth crossbeam 24 to prevent the fifth crossbeam 24 from being deformed by impact.

[0072] like Figure 9 As shown, the top of the rear panel 2 is hinged to the two side panels 3, allowing the rear panel 2 to be flipped open relative to the side panels 3 for easy loading and unloading of materials inside the cargo box. An inclined chain 9 is provided between the bottom of the rear panel 2 and the frame 5. The chain 9 is used to lock the rear panel 2 and the frame 5, and the angle between the chain 9 and the horizontal plane is 18°. This angle is reduced compared to existing angles, reducing the stress on the chain 9 and preventing material impact on the rear panel 2 from causing the chain 9 to break.

[0073] In one embodiment of the present invention, by hinged between the rear plate 2 and the side plate 3, the rear plate 2 can be opened to facilitate loading and unloading of materials in the cargo box. At the same time, an inclined chain 9 is provided between the bottom of the rear plate 2 and the frame 5 for locking, and the angle between the chain 9 and the horizontal plane is reduced, which can reduce the force on the chain 9 and prevent the chain 9 from breaking due to the impact of materials on the rear plate 2.

[0074] In one embodiment of the present invention, the upper part of the side plate 3 is configured as a straight plate 31, and the lower part of the side plate 3 is configured as an arc-shaped plate 32. The arc-shaped plate 32 is formed by bending the lower part of the side plate 3 15 times to form an arc shape, and then welded to the bottom plate 4 of the cargo box. The arc-shaped plate 32 structure of the lower part of the side plate 3 can effectively improve the stress on the side plate 3 of the cargo box. During the loading process, when the material impacts the arc of the arc-shaped plate 32, the arc will evenly distribute the force, making the side plate 3 uniformly stressed. At the same time, the transition between the side plate 3 and the bottom plate 4 using the arc-shaped plate 32 structure can prevent material adhesion, improve unloading speed, and increase work efficiency. Since the lower part of the side panel 3 needs to be bent to form an arc-shaped panel 32 structure, the thickness of the side panel 3 is less than that of the bottom panel 4. Furthermore, for cargo box structures with equal width, the lower part of the side panel 3 is set as an arc-shaped panel 32 structure, replacing part of the bottom panel 4 with an arc, which reduces the weight of the cargo box and lowers material costs.

[0075] Multiple outer curved plates 33 are disposed between the first crossbeam 34 and the second crossbeam 35, with half the width of the second crossbeam 35 covered by the outer curved plates 33. The lengths of the first crossbeam 34 and the second crossbeam 35 are the same as the length of the side plate 3. Compared with the existing broken beam structure, the structure of the first crossbeam 34 and the second crossbeam 35 has stronger resistance to deformation and no weld defects. Furthermore, the outer curved plates 33 are overlapped between the first crossbeam 34 and the second crossbeam 35, resulting in greater stability. When the side plate 3 is welded to the bottom plate 4, it is welded to the bottom plate 4 through the second crossbeam 35. In order to reduce the stress on the lower part of the weld of the side plate 3 and prevent stress concentration at the weld, the outer curved plates 33 are overlapped on the second crossbeam 35, with half the width of the second crossbeam 35 covered by the outer curved plates 33. This can reduce the stress on the lower part of the weld of the side plate 3.

[0076] On the other hand, one embodiment of the present invention also provides a vehicle, including the cargo box provided in any of the above embodiments. The vehicle can be a mining dump truck or other transport vehicle with a cargo box structure. The derivation process of the beneficial effects of the vehicle in one embodiment of the present invention is largely similar to the derivation process of the beneficial effects of the cargo box described above, and therefore will not be repeated here.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
