Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a wide-body dump truck body and a wide-body dump truck. Background Technology

[0002] Wide-body dump trucks with through-holes can complete rock and soil stripping and ore transportation tasks in open-pit mines and large-scale water conservancy projects. Their working characteristics are short transport distance and heavy load capacity. They are usually loaded with large electric shovels or hydraulic shovels and travel back and forth between the mining point and the unloading point.

[0003] Domestic wide-body dump trucks are mostly off-road wide-body vehicles, which are very large in size, weight / load capacity. In addition, the road conditions in mining areas are complex, resulting in high fuel consumption and significant emissions pollution.

[0004] Current wide-body dump truck cargo box designs typically involve simply thickening the steel material on a conventional road vehicle cargo box, resulting in a flat, rectangular main structure reinforced with bent steel plates. Numerous reinforcing ribs are placed on the bottom, front, and side plates to meet overall rigidity requirements. However, this structure presents several problems: the increased weight of the cargo box increases the overall vehicle weight, leading to higher fuel consumption and reduced carrying capacity, thus lowering the overall operational cost-effectiveness. The large amount of steel used also increases the manpower and material costs associated with welding during manufacturing. Furthermore, the flat, rectangular cargo box structure relies on the inherent rigidity of the steel plates and the support of the reinforcing ribs to overcome stress and strain, placing extremely high demands on welding quality and making it highly susceptible to weld cracking due to poor weld quality. Summary of the Invention

[0005] The purpose of this invention is to provide a wide-body dump truck body and a wide-body dump truck that can significantly reduce the weight of the truck body, ensure reliability, and increase the overall vehicle loading capacity.

[0011] In one embodiment, the side panel assembly includes a main side panel and a rear side panel. The front end of the rear side panel is fixedly connected to the rear end of the main side panel. In the longitudinal direction of the base plate, the top dimension of the rear side panel is smaller than the bottom dimension. The main side panel includes a first straight plate portion, a first arc-shaped portion, and a first connecting portion. The first arc-shaped portion is connected between the first straight plate portion and the first connecting portion. The first straight plate portion is substantially perpendicular to the body portion of the base plate. The first connecting portion is connected to the body portion of the base plate. The rear side panel includes a second straight plate portion, a second arc-shaped portion, and a second connecting portion. The second arc-shaped portion is connected between the second straight plate portion and the second connecting portion. The second straight plate portion is substantially perpendicular to the upturned portion of the base plate. The second connecting portion is connected to the upturned portion of the base plate.

The flue assembly is located at the bottom of the main side panel, the rear flue is located at the bottom of the rear side panel, the upper side beam is located at the top of the main side panel, and the cover plate covers the upper side beam. A plurality of ring beams are spaced apart on the main side panel, and one end of each ring beam is fixedly connected to the flue assembly. The front tail rib is located at the connection between the main side panel and the rear side panel, and is connected to both the main side panel and the rear side panel. One end of the front tail rib is connected to the upper side beam, and the other end is aligned with and connected to the third crossbeam. The rear tail rib is located at the end of the rear side panel away from the main side panel. One end of the rear tail rib is connected to the rear flue, and the other end is connected to the tail of the upper side beam and the cover plate.

[0013] In one embodiment, the front panel assembly includes a front panel, a middle horizontal rib, side horizontal ribs, vertical ribs, and a cylinder mounting plate.

The cylinder mounting plate is located in the area enclosed by the middle horizontal rib and the vertical rib, and the two sides of the cylinder mounting plate overlap with the two vertical ribs respectively.

[0014] In one embodiment, the bottom of the front panel is provided with a plurality of spaced protrusions, wherein two of the protrusions correspond to the vertical ribs and the longitudinal beams of the bottom plate assembly, and the other two protrusions correspond to the flue assembly of the side plate assembly; or, the top edge of the front panel is formed with a sill plate, the sill plate is bent toward the side of the front panel away from the loading cavity to form a bent plate that is inclined at a certain angle relative to the front panel, and the bending angle of the sill plate is consistent with the inclination angle of the brim assembly relative to the front panel.

Moreover, the arc-shaped side plate assembly can absorb the impact energy of the cargo through the elastic deformation of the plate itself, extending the service life of the cargo box and reducing the impact of the cargo box on the whole vehicle, thus improving the reliability of the wide-body dump truck body. At the same time, the upward tilting of the rear end of the bottom plate assembly can ensure the concentration of materials and ensure the loading capacity without a tailgate.

[0025] To further illustrate the technical methods and effects of the present invention in order to achieve the intended purpose, the specific implementation methods, structure, features and effects of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0026] Please refer to Figure 1An embodiment of the wide-body dump truck body of the present invention includes a floor assembly 11, side panel assemblies 13, a front panel assembly 15, and a visor assembly 17. Two side panel assemblies 13 are respectively connected to two opposite sides of the floor assembly 11. The front panel assembly 15 is connected to one end of the floor assembly 11 and the side panel assemblies 13. The floor assembly 11, side panel assemblies 13, and front panel assembly 15 together form a loading cavity for loading ore, etc. The visor assembly 17 is connected to the side panel assemblies 13 and the front panel assembly 15 and extends towards the side opposite to the loading cavity. The floor assembly 11 and the side panel assemblies 13 overlap at their connection points, and the cross-section of the side panel assembly 13 near its connection with the floor assembly 11 is arc-shaped. The end of the floor assembly 11 away from the front panel assembly 15 curves upwards towards the loading cavity. The ends of the floor assembly 11 and the side panel assemblies 13 away from the front panel assembly 15 are open to facilitate material unloading when the truck body is lifted.

[0027] In this embodiment of the wide-body dump truck body, by forming the side panel assembly into an arc shape and connecting the side panel assembly and the bottom plate assembly in an overlapping manner, the strength requirements and usage conditions of the cargo body can be met without adding a large number of reinforcing ribs, thereby reducing the weight of the cargo body and achieving the purpose of lightweighting. Moreover, the arc-shaped side panel assembly can absorb the impact energy of the cargo through the elastic deformation of the sheet metal itself, extending the service life of the cargo body and reducing the impact of the cargo body on the whole vehicle, thus improving the reliability of the wide-body dump truck body. At the same time, the upward tilting of the rear end of the bottom plate assembly can ensure the concentration of materials and ensure the loading capacity without a tailgate.

[0028] In this embodiment, the overlap length of the base plate assembly 11 and the side plate assembly 13 can be greater than or equal to 50 mm.

[0029] In this embodiment, please refer to Figure 2 and Figure 3 The base plate assembly 11 includes a base plate 111, longitudinal beams 113, a first crossbeam 115, a second crossbeam 116, a third crossbeam 117, and hinged supports 119. The base plate 111 has a front facing the loading cavity and a back facing away from the loading cavity. The longitudinal beams 113, first crossbeam 115, second crossbeam 116, third crossbeam 117, and hinged supports 119 are all connected to the back of the base plate 111. Two longitudinal beams 113 are spaced apart and extend longitudinally along the base plate 111 (i.e., the longitudinal direction of the dump truck). The first crossbeam 115 and second crossbeam 116 are spaced apart between the two longitudinal beams 113. Two hinged supports 119 are respectively connected to one end of the two longitudinal beams 113, and the third crossbeam 119 is located at the connection between the hinged supports 119 and the longitudinal beams 113.

[0030] Specifically, the base plate 111 includes a body portion 1111 and an upturned portion 1113. The upturned portion 1113 is located at the end of the base plate assembly 11 away from the front plate assembly 15, causing one end of the base plate assembly 11 to be upturned. The upturned angle of the upturned portion 1113 relative to the body portion 1111 is greater than or equal to 8°. Specifically, the longitudinal dimension of the upturned portion 1113 in the base plate 111 is approximately one-third of the dimension of the body portion 1111, such that the upturned portion 1113 is upturned approximately at one-quarter of the length of the base plate 111.

[0031] Specifically, the base plate 111 is a single plate, and its material can be wear-resistant plate 450 (wear-resistant plate 450 is a steel plate with an average Brinell hardness of 450).

[0032] Specifically, the front end of the longitudinal beam 113 is flush with the front end of the base plate 111. The longitudinal beam 113 is a hollow frame, and multiple spaced-apart first support ribs 121 are provided inside the longitudinal beam 113. By making the longitudinal beam 113 hollow, the weight of the wide-body dump truck body can be further reduced, while the first support ribs 121 can ensure the strength of the longitudinal beam 113. Specifically, in this embodiment, each longitudinal beam 113 is provided with 8 first support ribs 121. More specifically, the multiple first support ribs 121 are respectively aligned with the two sides of the first crossbeam 115.

[0033] Specifically, the width of the first crossbeam 115 is greater than the width of the second crossbeam 116, and multiple first crossbeams 115 and multiple second crossbeams 116 are alternately arranged. Specifically, both the first crossbeam 115 and the second crossbeam 116 are perpendicular to the longitudinal beam 113.

[0034] Specifically, the third crossbeam 117 is provided to pass through the rear end of the longitudinal beam 113 and the front end of the hinge support 119. That is, the bottom of the rear end of the longitudinal beam 113 and the front end of the hinge support 119 are both provided with openings, the third crossbeam 117 is inserted into the openings, and the upper part of the openings of the rear end of the longitudinal beam 113 and the front end of the hinge support 119 are both pressed on the third crossbeam 117.

[0035] Specifically, the third crossbeam 117 is a hollow frame, and multiple spaced-apart second support ribs 122 are provided inside the third crossbeam 117. By making the third crossbeam 117 hollow, the weight of the wide-body dump truck body can be further reduced, while the second support ribs 122 ensure the strength of the third crossbeam 117. Specifically, in this embodiment, there are eight second support ribs 122. Specifically, four of the second support ribs 122 are aligned with the two sides of the two longitudinal beams 113 respectively. The dimension of the third crossbeam 117 in the transverse direction of the longitudinal beams 113 (i.e., the left-right direction of the dump truck) is larger than the dimension of the bottom plate 111.

[0036] Specifically, the hinge support 119 is aligned with the longitudinal beam 113. The hinge support 119 includes two spaced-apart opposing vertical plates 1191 and an intermediate stiffening plate. The intermediate stiffening plate connects the two vertical plates 1191. Hinge holes 1193 are respectively provided at corresponding positions on the two vertical plates 1191, through which the hydraulic cylinders of the lifting compartment can be hinged to the hinge support 119. More specifically, the positions of the hinge holes 1193 on the two hinge supports 119 are also corresponding. Specifically, the thickness of the vertical plates 1191 is much greater than the thickness of the bottom plate 111, the longitudinal beam 113, the first crossbeam 115, the second crossbeam 116, and the third crossbeam 117. By aligning the hinge support 119 with the longitudinal beam 113, the overall rigidity of the wide-body dump truck compartment is increased, and its impact resistance is strengthened.

[0037] Specifically, the body portion 111 of the base plate 111 is provided with a plurality of triangular ribs 124 at one end away from the upturned portion 1113, and at least one triangular rib 124 is aligned with one side of the longitudinal beam 113.

[0038] In this embodiment, please refer to Figure 4 and Figure 5 The side panel assembly 13 includes a main side panel 131 and a rear side panel 133. The front end of the rear side panel 133 is fixedly connected to the rear end of the main side panel 131. In the longitudinal direction of the base plate 111, the top dimension of the rear side panel 133 is smaller than the bottom dimension. Please refer to [the relevant documentation / reference]. Figure 6 The main side panel 131 includes a first straight section 1311, a first arcuate section 1313, and a first connecting section 1315. The first arcuate section 1313 connects the first straight section 1311 and the first connecting section 1315. The first straight section 1311 is generally perpendicular to the body section 1111 of the base plate 111, and the first connecting section 1315 is connected to the body section 1111 of the base plate 111. The rear side panel 133 includes a second straight section, a second arcuate section, and a second connecting section. The second arcuate section connects the second straight section and the second connecting section. The second straight section is generally perpendicular to the upturned section 1113 of the base plate 111, and the second connecting section is connected to the upturned section 1113 of the base plate 111. Corresponding to the upturned section 1113, the bottom of the rear side panel 133 is also inclined at a certain angle relative to the body section 1111 of the base plate 111. The side panel assembly 13 is composed of two parts, the main side panel 131 and the rear side panel 133, which not only satisfies the overall arc-shaped structure, but also ensures that the upward angle of the tail is consistent with the upward angle of the bottom plate 111.

[0039] Specifically, the first arc-shaped portion 1313 and the second arc-shaped portion can be approximately a quarter-circle arc. The first arc-shaped portion 1313 is tangent to the first straight plate portion 1311 and the first connecting portion 1315, respectively, and the second arc-shaped portion is tangent to the second straight plate portion and the second connecting portion, respectively.

[0040] Specifically, the side panel assembly 13 also includes a flue assembly 135, a rear flue 137, an upper side beam 139, a cover plate 141, a ring beam 143, a front tail rib 145, and a rear tail rib 147. The flue assembly 135 is located at the bottom of the main side panel 131, the rear flue 137 is located at the bottom of the rear side panel 133, the upper side beam 139 is located at the top of the main side panel 131, and the cover plate 141 covers the upper side beam 139. Multiple ring beams 143 are spaced apart on the main side panel 131, and one end of each ring beam 143 is fixedly connected to the flue assembly 135. The front tail rib 145 is located at the connection between the main side panel 131 and the rear side panel 133, and is connected to both the main side panel 131 and the rear side panel 133. One end of the front tail rib 145 is connected to the upper side beam 139, and the other end is aligned with and connected to the third crossbeam 117. The rear tail rib 147 is located at the end of the rear side plate 133 away from the main side plate 131. One end of the rear tail rib 147 is connected to the rear flue 137, and the other end is connected to the tail of the upper side beam 139 and the cover plate 141. Since the top dimension of the rear side plate 133 is smaller than the bottom dimension, the rear tail rib 147 is arranged at an angle. The angle between the rear tail rib 147 and the front tail rib 145 can be an acute angle, and the sum of this acute angle and the inclination angle of the bottom of the rear side plate 133 is 90°. Specifically, the number of ring beams 143 is the same as the number of first crossbeams 115, and their positions correspond to those of the first crossbeams 115. The arrangement of the ring beams 143 can further enhance the strength of the arc position of the side plate assembly 13, and the control of their number reduces the overall weight and welding workload.

[0041] Specifically, the rear tail rib 147 includes an upper rear tail rib 1471 and a lower rear tail rib 1473 that are connected to each other. The upper rear tail rib 1471 is connected to the tail of the upper side beam 139 and the cover plate 141, and the lower rear tail rib 1473 is connected to the rear flue 137.

[0042] Specifically, the two side panel assemblies 13 are respectively disposed on both sides of the base plate assembly 11, forming a left side panel assembly and a right side panel assembly respectively.

[0043] Specifically, the main side panel 131 is a single piece of material, which can be made of wear-resistant plate 450. The rear side panel 133 can also be made of wear-resistant plate 450.

[0044] In this embodiment, please refer to Figure 7 and Figure 8The front panel assembly 15 includes a front panel 151, a central horizontal rib 153, side horizontal ribs 155, vertical ribs 157, and a cylinder mounting plate 159. The central horizontal rib 153, side horizontal ribs 155, vertical ribs 157, and cylinder mounting plate 159 are all located on the side of the front panel 151 facing away from the loading cavity. The central horizontal rib 153 and side horizontal ribs 155 are arranged transversely along the bottom plate 111 on the front panel 151. The vertical ribs 157 are arranged on the front panel 151 in a direction perpendicular to the central horizontal rib 153. The two vertical ribs 157 are arranged parallel to each other at intervals. The central horizontal rib 153 is located between the two vertical ribs 157. Side horizontal ribs 155 are respectively provided on the outer side of the two vertical ribs 157. The cylinder mounting plate 159 is located in the area enclosed by the central horizontal rib 153 and the vertical ribs 157, and the two sides of the cylinder mounting plate 159 overlap with the two vertical ribs 157 respectively. Specifically, the two sides of the cylinder mounting plate 159 are arc-shaped, and the thickness of the cylinder mounting plate 159 is higher than that of the vertical rib 157.

[0045] Specifically, the bottom of the front panel 151 is provided with a plurality of spaced protrusions 1511, two of which are provided to correspond to the vertical ribs 157 and the longitudinal beams 113 of the bottom plate assembly 11, and the other two protrusions 1511 are provided to correspond to the flue assembly 135 of the side panel assembly 13.

[0046] Specifically, a flange 1513 is formed on the top edge of the front panel 151. The flange 1513 is bent toward the side of the front panel 151 opposite to the loading cavity to form a bent plate that is inclined at a certain angle relative to the front panel 151. The bending angle of the flange 1513 is consistent with the inclination angle of the brim assembly 17 relative to the front panel 151.

[0047] Specifically, the front panel 151 is a single plate, and its material can be wear-resistant plate 450.

[0048] In this embodiment, the brim assembly 17 includes a brim plate 171, a front protruding edge 173, and a side protruding edge 175. The front protruding edge 173 is located on the side of the brim plate 171 away from the front plate assembly 15. The two opposite ends of the brim plate 171 are respectively connected to the side protruding edges 175, and the two side protruding edges 175 are respectively connected to the front end of the flue assembly 135 of the two side plate assemblies 13. The brim plate 171 is connected to the edge plate 1513 of the front plate 151 of the front plate assembly 15.
