[0024] One embodiment of this utility model has the following advantages or beneficial effects:
[0025] This utility model provides a mining dump truck body and a mining dump truck. The straight section has a relatively straight structure and can contact the mounting surface of the frame without modifying the main frame structure, thus improving versatility. During loading, guided by the inclined section, the cargo slides down the inclined section to the straight section, reducing the risk of material residue. The cargo first impacts the upward-curving inclined section before sliding to the straight section, absorbing the impact force and reducing wear on the straight section, extending its service life. During cargo transportation, the upward-bending inclined section acts as a temporary baffle, preventing cargo from falling off the body and reducing road pollution and cargo damage. During unloading, the cargo gathers along the inclined section to the straight section, shifting the center of gravity forward and reducing the lifting torque of the lifting device, saving unloading production costs. Simultaneously, due to the relatively forward shift of the center of gravity, the risk of tipping over is reduced when going uphill, improving the dump truck's driving stability and climbing safety.

[0044] This embodiment provides a mining dump truck, which includes a frame and a mining dump truck body. The mining dump truck body is mounted on the frame and can rotate relative to the frame. The mining dump truck body is used to load goods. When the mining dump truck body rotates relative to the frame, the goods are unloaded from the mining dump truck body, realizing the unloading process.
[0045] In one embodiment, the mining dump truck includes a lifting device, which may be a lifting cylinder. The lifting device is mounted on the chassis, and one end of the mining dump truck body is connected to the output end of the lifting device, while the other end is rotatably connected to the chassis. When the lifting device drives the mining dump truck body to rise, the mining dump truck body can rotate relative to the chassis to achieve the unloading process.
[0046] This embodiment also provides a mining dump truck body, such as... Figure 1 As shown, the mining dump truck includes a reinforcing frame 1 and a body 2. The body 2 is disposed on the reinforcing frame 1. For example, the reinforcing frame 1 is disposed on the outer side wall of the body 2. The reinforcing frame 1 provides a certain support force for the body 2 and can increase the structural strength of the body 2.
[0047] Among them, the reinforcing frame 1 can adopt I-beam reinforcing ribs. Compared with the traditional rib grooves used in the reinforcing frame 1, the cross-sectional area of the reinforcing frame 1 is smaller under the same bending stiffness, which reduces the weight of the reinforcing frame 1, increases the material utilization rate, optimizes the welding process of the carriage, and reduces the manufacturing difficulty and cost.
[0048] The compartment 2 has at least one plane, which is parallel to the horizontal plane. The height direction of the compartment 2 is perpendicular to the plane. The length direction and the width direction of the compartment 2 are two mutually perpendicular directions within the plane, that is, the length direction, the width direction, and the height direction of the compartment 2 are mutually perpendicular to each other. The length direction of the compartment 2 is identified by D1, the width direction by D2, and the height by D3.
[0049] Specifically, the container 2 includes a bottom plate 21, a top plate 22, side plates 23, and a middle plate 24. The two side plates 23 are respectively disposed on both sides of the bottom plate 21 along the width direction of the container 2. One side of the bottom plate 21 along the length direction of the container 2 is connected to the top plate 22 through the middle plate 24. A loading space is formed between the bottom plate 21, the top plate 22, the side plates 23, and the middle plate 24. The middle plate 24 is disposed on one side of the bottom plate 21 along the length direction of the container 2. One end of the middle plate 24 along the height direction of the container 2 is connected to the bottom plate 21, and the other end is connected to the top plate 22. That is, along the height direction of the container 2, the bottom surface of the top plate 22 is higher than the top surface of the bottom plate 21.
[0050] The base plate 21, top plate 22, side plate 23, and middle plate 24 can be fixed to the reinforcing frame 1 by bolts or welding. During prolonged operation, if the base plate 21, top plate 22, side plate 23, and middle plate 24 gradually wear out and become unusable, they can be removed from the reinforcing frame 1 by hammering or other methods. New base plates 21, top plate 22, side plate 23, and middle plate 24 can then be installed on the reinforcing frame 1, reducing cost waste.
[0051] Among them, such as Figures 1-2 As shown, the bottom plate 21 includes a straight section 211, one end of which is connected to the middle plate 24 along the length of the body 2, and the straight section 211 is mounted on the frame.
[0052] For example, the plane containing the straight section 211 is parallel to the plane containing the length direction and the width direction of the body 2. The structure of the straight section 211 is relatively straight. The straight section 211 can contact the mounting surface of the frame. That is, the straight section 211 can be adapted to the flat bottom frame without modifying the main structure of the frame, thus improving versatility.
[0053] Among them, such as Figures 1-2 As shown, the bottom plate 21 also includes an inclined portion 212. Along the length of the body 2, one end of the straight portion 211 is connected to the middle plate 24, and the other end is connected to the inclined portion 212. The inclined portion 212 and the straight portion 211 are arranged at an angle. Along the height of the body 2, the end of the inclined portion 212 away from the straight portion 211 is higher than the connection position between the straight portion 211 and the inclined portion 212.
[0054] For example, the inclined portion 212 is inclined relative to the straight portion 211 in a direction away from the frame, that is, it is partially bent upward at the rear end of the base plate 21, without affecting the flatness of the straight portion 211.
[0055] During loading, guided by the inclined section 212, the cargo slides down to the straight section 211, reducing the risk of cargo residue. The cargo first impacts the upward-curving inclined section 212 before sliding to the straight section 211, absorbing the impact force and reducing wear on the straight section 211, thus extending its service life. During transport, the upward-bending inclined section 212 acts as a temporary baffle, preventing cargo from falling from the container body 2 and reducing road pollution and cargo damage. During unloading, the cargo converges along the inclined section 212 to the straight section 211, shifting the center of gravity forward and reducing the lifting torque of the lifting device, thus saving unloading costs. Simultaneously, the forward shift of the center of gravity reduces the risk of tipping over when going uphill, improving the driving stability and climbing safety of the dump truck.
[0056] The base plate 21 provided in this embodiment is not an overall boat-shaped or V-shaped structure. Instead, it adopts a combination design of a straight section 211 and an inclined section 212. While the straight section 211 of the base plate 21 maintains an overall straight structure, only the tail end of the base plate 21 is partially raised to form the inclined section 212. The straight section 211 can be directly installed on a standard flat-bottom frame without additional padding or modification. It is compatible with standard flat-bottom frames and also has the advantages of clean unloading, good passability, and easy lifting.
[0057] Specifically, the included angle between the inclined portion 212 and the straight portion 211 is 10° to 14°. For example, the included angle between the inclined portion 212 and the straight portion 211 can be 10°, 12°, or 14°, such as 12°.
[0058] In this manner, the angle between the inclined section 212 and the straight section 211 is not too large, avoiding the problem of a larger tilt angle affecting the loading space volume and structural stress concentration. The angle between the inclined section 212 and the straight section 211 is also not too small, and the rear end of the bottom plate 21 is not excessively raised, giving the rear end of the bottom plate 21 a certain ground clearance, for example, increasing it by 5cm to 7cm. When the rear door is not installed, the inclined section 212 can act as a baffle to prevent goods from rolling off. Simultaneously, this tilt angle allows goods to slide a certain distance towards the middle plate 24, shifting the center of gravity forward and reducing the risk of goods falling off during sharp turns or on slopes. Furthermore, goods can slide down the inclined section 212, resulting in clean unloading without the need for secondary cleaning, reducing maintenance costs.
[0059] In one embodiment, along the height direction of the compartment 2 and away from the bottom plate 21, the distance between the two side plates 23 along the width direction of the compartment 2 gradually decreases. That is, along the width direction of the compartment 2, the distance between the ends of the two side plates 23 away from the bottom plate 21 is less than the width of the bottom plate 21.
[0060] Specifically, the container 2 adopts a wedge-shaped structure that is wider at the bottom and narrower at the top. Since the side panels 23 need to withstand the lateral pressure of the cargo, and the pressure increases with the depth of the cargo, the width of the side panels 23 also increases accordingly. This maximizes the cross-sectional area at the point of maximum stress, improving the uniformity of stress distribution. Furthermore, the upper part of the side panels 23 experiences less pressure, thus reducing the width of the side panels 23 and minimizing material waste. Simultaneously, during unloading, the cargo can slide down the inclined side panels 23, reducing the risk of residue sticking to the container and facilitating the cleaning of the container 2.
[0061] In one embodiment, such as Figure 1 and Figure 3 As shown, the mining dump truck body also includes a first arc plate 25, and the bottom plate 21 is connected to the side plate 23 through the first arc plate 25.
[0062] For example, the side edge of the bottom plate 21 along the width direction of the compartment 2 and the lower edge of the first arc plate 25 along the height direction of the compartment 2 are welded together. Along the height direction of the compartment 2, the upper edge of the first arc plate 25 and the lower edge of the side plate 23 are welded and fixed together. In this way, the bottom plate 21 and the side plate 23 are connected by an arc plate transition, reducing stress concentration at the connection point and improving stress distribution uniformity. Simultaneously, goods can fall along the side plate 23 through the first arc plate 25 to the bottom plate 21. The first arc plate 25 has no dead angles, ensuring smooth unloading of goods.
[0063] In one embodiment, such as Figure 1 and Figure 3 As shown, the mining dump truck body also includes a second arc plate 26, and the bottom plate 21 is connected to the intermediate plate 24 through the second arc plate 26.
[0064] For example, the side edge of the bottom plate 21 along the length of the body 2 and the lower edge of the second arc plate 26 along the height of the body 2 are welded together. Along the height of the body 2, the upper edge of the second arc plate 26 and the lower edge of the intermediate plate 24 are welded and fixed together. In this way, the bottom plate 21 and the intermediate plate 24 are connected by an arc plate transition, reducing stress concentration at the connection point and improving stress distribution uniformity. Simultaneously, goods can fall along the side plate 23 onto the bottom plate 21 via the second arc plate 26, which has no dead angles, ensuring smooth unloading of goods.
[0065] In one embodiment, such as Figures 1-4As shown, the reinforced frame 1 includes a frame 14, a crossbeam 11, and a longitudinal beam 12. The crossbeam 11 is located on the side of the body 2 away from the loading space. The crossbeam 11 is located inside the frame 14 and connected to the frame 14. The longitudinal beam 12 is located on the side of the body 2 away from the loading space. The longitudinal beam 12 is located inside the frame 14 and connected to the frame 14. The crossbeam 11 and the longitudinal beam 12 are arranged at an angle.
[0066] For example, the included angle between the crossbeam 11 and the longitudinal beam 12 can be 30°, 60°, 90°, etc. For instance, the crossbeam 11 extends approximately along the length of the compartment 2, and the longitudinal beam 12 extends approximately along the width of the compartment 2. The included angle between the crossbeam 11 and the longitudinal beam 12 is 90°. The crossbeam 11 and the longitudinal beam 12 act as reinforcing ribs, reducing the occurrence of local buckling and deformation under shear force, and significantly improving the structural strength and stability of the compartment 2.
[0067] The crossbeams 11 and longitudinal beams 12 can both be located on the outer side wall of the compartment 2 away from the loading space, or they can be located in different areas of the compartment 2. For example, along the length of the compartment 2, the crossbeam 11 extends along the edge of the top plate 22 away from the bottom plate 21 to the middle plate 24 and the second arc plate 26, and then continues to the edge of the bottom plate 21 away from the top plate 22. The crossbeam 11 bends at the position corresponding to the middle plate 24, but the crossbeam 11 extends approximately along the length of the compartment 2. For example, the longitudinal beam 12 is located on the bottom plate 21, and extends along the width of the compartment 2 to both sides to the first arc plate 25, and then continues to the side plate 23. The longitudinal beam 12 bends at the first arc plate 25, and the longitudinal beam 12 has a U-shaped structure, allowing it to simultaneously increase the structural strength of the side plate 23, the first arc plate 25, and the bottom plate 21. For example, both the crossbeam 11 and the longitudinal beam 12 are provided on the base plate 21, further increasing the structural strength of the base plate 21.
[0068] Among them, there are multiple crossbeams 11, which are arranged in parallel at intervals and along the width direction of the compartment 2; and / or, there are multiple longitudinal beams 12, which are arranged in parallel at intervals and along the length direction of the compartment 2.
[0069] Multiple crossbeams 11 and multiple longitudinal beams 12 form a small grid structure, which can improve the structural strength of the box body 2 in both the length and width directions. Furthermore, the even distribution of the crossbeams 11 and longitudinal beams 12 increases the uniformity of the box body 2's stiffness. Simultaneously, the box body 2 needs to bear the weight of the cargo, vehicle inertia, and centrifugal force during turns, all of which can be transmitted to the frame along the path of the cross grid, optimizing the transmission path and reducing additional bending moments.
[0070] This lightweight design reduces energy consumption during empty return trips, increases the capacity of a single trip, and thus improves overall economic efficiency. Lightweight design also helps reduce fuel consumption, conserve energy, reduce emissions, and decrease greenhouse gas emissions, aligning with green and environmentally friendly requirements.
[0071] In one embodiment, such as Figures 1-4 As shown, the reinforcing frame 1 also includes a connector 13, which is located between the crossbeam 11 and the longitudinal beam 12 and is connected to the crossbeam 11 and the longitudinal beam 12 respectively. The connector 13 is located at the intersection between the crossbeam 11 and the longitudinal beam 12, which increases the connection strength and improves the structural stability of the reinforcing frame 1.
[0072] In one embodiment, such as Figure 4 As shown, the reinforcing frame 1 also includes a connecting beam 6, which is disposed between the intermediate plate 24 and the bottom plate 21. The connecting beam 6 is at least partially in contact with the frame. Exemplarily, the connecting beam 6 has two side arms, which are perpendicular to each other and connected at their closest points, i.e., the connecting beam 6 has an L-shaped structure. One side arm of the connecting beam 6 is connected to the intermediate plate 24, and the other side arm is connected to the bottom plate 21. The connecting beam 6 protrudes from the body 2. The fact that the connecting beam 6 is at least partially in contact with the frame increases the contact area with the frame and further improves the installation stability of the body on the frame.
[0073] In one embodiment, such as Figure 1 and Figure 5 As shown, a rotating seat 3 and a lifting seat 4 are provided on the side of the reinforced frame 1 away from the loading space. The lifting seat 4 is located at one end of the bottom plate 21 along the length of the body 2 and facing the middle plate 24. The rotating seat 3 is located at one end of the bottom plate 21 along the length of the body 2 and away from the middle plate 24. The rotating seat 3 is rotatably connected to the frame. The lifting seat 4 is used to connect to the output end of the lifting device.
[0074] For example, the rotating seat 3 is provided with a shaft hole, and the rotating shaft passes through the shaft hole and the frame, so that the entire carriage can rotate relative to the rotating shaft.
[0075] For example, the output end of the lifting device can be directly connected to the lifting seat 4, or it can be not connected to the lifting seat 4, that is, the output end of the lifting device abuts against the lifting seat 4 to realize the lifting of the carriage. The lifting seat 4 can be set at the intersection between the crossbeam 11 and the longitudinal beam 12 to distribute the concentrated force transmitted by the lifting seat 4 to the reinforcing frame 1 and reduce the risk of fatigue cracking of the weld.
[0076] For example, the rotating seat 3 and the lifting seat 4 can be set on the longitudinal beam 12 to minimize the torque transmission path, ensure the rationality of the stress on the reinforcing frame 1, and facilitate modular assembly.
[0077] In one embodiment, a limiting plate 5 is provided on the side of the reinforcing frame 1 away from the loading space, and the limiting plate 5 is used to limit the distance between the body 2 and the frame.
[0078] For example, the frame is provided with a first limiting block (not shown in the figure) and a second limiting block (not shown in the figure) corresponding to the limiting plate 5. Along the height direction of the cargo box 2, the first limiting block is located above the second limiting block. The first limiting block can be called the upper limiting block, and the second limiting block can also be called the lower limiting block. When the lifting device lifts the cargo box 2 to the maximum tilt angle, the limiting plate 5 directly contacts the first stop block of the frame, which serves to tilt the upper limit block, and the lifting device stops rising continuously, preventing the cargo box 2 from tipping over. When unloading and falling back down, the limiting plate 5 contacts the second limiting block of the frame, which serves to lower the lower limit block, allowing the cargo box 2 to fall back smoothly onto the frame, preventing a rigid collision caused by the cargo box 2 falling directly onto the frame due to inertia. This method can prevent the cargo box 2 from overturning and also prevent it from overshooting during the fall.
