Description

Technical Field

[0001] This utility model relates to the field of special vehicle manufacturing technology, and in particular to a dump truck. Background Technology

[0002] Currently, the mainstream materials used in the manufacture of existing dump trucks are ordinary steel plates, manganese steel plates, and high-strength steel plates, which have long been widely used in the industry. To ensure sufficient strength to cope with complex and ever-changing transportation environments and cargo loading requirements, traditional dump trucks adopt a relatively heavy-duty structural design. The inner and outer lining plates of key structures such as the underframe I-beams and crossbeams all require thicker plates to ensure that the underframe does not deform or break under immense pressure. At the same time, horizontal and vertical ribs are added to the front, bottom, side, and rear panels to enhance the overall structural strength. This design philosophy has ensured the reliability and durability of vehicles to a certain extent in the past, but with market development and changes in user needs, many problems have gradually emerged.

[0003] The heavy weight of traditional dump trucks is one of the most significant problems. Due to the use of thicker sheet metal and increased structural rigidity, the vehicle's weight is significantly increased. This not only directly leads to higher fuel consumption and increased operating costs, but also, under the current national regulations on overloading and the strong promotion of standard-load and safe transportation, the heavier vehicle limits the cargo capacity, reduces transportation efficiency, and puts the vehicle at a disadvantage in market competition.

[0004] The small effective volume of the cargo box is also a problem for traditional dump trucks. The increased thickness of the sheet metal and the addition of ribs to enhance structural strength occupy a significant amount of internal space, resulting in a smaller effective cargo volume that can be loaded within the same vehicle body size. This directly reduces the amount of cargo that can be transported per trip, impacting transportation efficiency and making it difficult to meet users' demands for improved transportation efficiency.

[0005] High unloading residue rates are also a problem with traditional dump trucks. Their cargo box structure and materials make it easy for cargo residue to remain during unloading. A high unloading residue rate not only wastes goods and increases transportation costs, but also, when transporting polluting goods, the residue may pollute the environment, which is inconsistent with the concept of green and environmentally friendly development.

[0006] The susceptibility to corrosion and short service life of the carriages are also drawbacks of traditional materials and designs. When faced with corrosive goods or harsh operating environments, carriages made of traditional materials are easily corroded, leading to a decrease in structural strength, damage, and deformation, thus shortening the vehicle's service life and increasing maintenance and replacement costs.

[0007] The low residual value of the vehicle is also a significant concern. Due to the numerous problems mentioned above, the performance and value of traditional dump trucks decline sharply after a period of use, resulting in low residual value. This not only affects the economic interests of the vehicle owner but also hinders the recycling and reuse of the vehicle, leading to a waste of resources.

[0008] With the government's strict control over overloading and strong advocacy for standard-load and safe transportation, user demands for dump trucks have undergone profound changes. Today, users no longer focus solely on vehicle strength and basic transportation functions, but demand higher specifications for parameters such as effective volume, overall weight, driving stability, and service life. The design philosophy of increasing vehicle strength through heightening, thickening the frame, and reinforcing the vehicle, as employed a few years ago, is no longer suitable for market development and user needs. Users urgently require dump trucks with higher driving stability, lighter weight, larger volume, longer service life, and higher residual value to improve transportation efficiency, reduce costs, ensure safety, and achieve greater economic benefits.

[0009] Despite ongoing efforts within the industry to improve the design and manufacturing processes of traditional dump trucks in an attempt to address these issues, no breakthrough has yet been achieved. Some improvements often only alleviate certain problems to a limited extent, failing to fundamentally resolve the inherent drawbacks of traditional dump trucks, such as their heavy weight, small volume, and short service life. Summary of the Invention

[0010] This utility model provides an aluminum alloy front-top dump truck, which has the advantages of light weight, large volume, long service life, low unloading residue rate and high residual value. It can effectively solve the drawbacks of traditional dump trucks, such as large weight, small volume and short service life.

[0011] To solve the above problems, the technical solution adopted by this utility model is: It includes a chassis assembly, on the bottom of which a running gear assembly is mounted and on top of which a cargo box assembly is mounted; at the front end of the cargo box assembly, a hydraulic cylinder assembly is mounted between the chassis assembly and the cargo box assembly; Both the underframe assembly and the carriage assembly are made of aluminum alloy. The carriage assembly includes a front panel assembly and a rear panel assembly located at the front and rear ends of the carriage assembly, side panel assemblies on the left and right sides, and a bottom panel assembly. The underframe assembly includes an underframe I-beam and an underframe crossbeam installed between the underframe I-beams. Both the underframe I-beam and the underframe crossbeam are aluminum alloy open-form material structures. The front panel assembly includes a front panel bottom plate with front panel frames installed on the left and right sides, a front panel upper frame installed on the top, and a front panel central vertical rib installed on the outer side. A front panel cylinder central vertical rib is installed between the front panel central vertical ribs. The front panel frames, front panel upper frame, front panel central vertical ribs, and front panel cylinder central vertical ribs are all aluminum alloy open mold material structures, and the front panel bottom plate is an aluminum alloy sheet structure. The side plate assembly includes a side plate bottom plate with a side plate bottom frame installed at the bottom, a side plate top frame installed at the top, and a side plate rear column installed at the rear end. The side plate bottom frame, the side plate top frame, and the side plate rear column are all aluminum alloy open-form material structures, and the side plate bottom plate is an aluminum alloy open-form material structure. The rear panel assembly includes a rear panel base plate with rear panel frames installed on the left and right sides, a rear panel upper frame installed on the top, and a rear panel lower frame installed on the bottom. The rear panel frames, the rear panel upper frame, and the rear panel lower frame are all aluminum alloy molded material structures, and the rear panel base plate is an aluminum alloy sheet structure. The base plate assembly includes a base plate with a base plate crossbeam laid on top, a base plate connecting plate installed at the front end, and a base plate rear crossbeam installed at the rear end. The base plate crossbeam and the base plate rear crossbeam are both aluminum alloy open mold material structures, and the base plate and the base plate connecting plate are aluminum alloy sheet structures.

[0012] A more specific technical solution than the above-mentioned technical solution is that the bottom plate crossbeam and the bottom plate rear crossbeam are respectively welded to the side plate lower frame to form a frame structure.

[0013] Furthermore, the vertical ribs in the front plate cylinder are used to install the cylinder and are connected to the bottom plate connecting plate to form a frame structure.

[0014] Furthermore, the vertical ribs in the front plate are directly opposite the I-beams of the base frame.

[0015] Furthermore, the rear panel assembly also includes a rear panel small door frame, and the rear panel small door frame is provided with a rear panel small door central vertical rib; wherein, the rear panel small door frame and the rear panel small door central vertical rib are aluminum alloy mold material structures.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: 1. This utility model achieves the goal of minimizing weight and achieving a lightweight design by limiting both the chassis assembly and the carriage assembly to aluminum alloy materials and adjusting the specific structure of the chassis assembly and the carriage assembly.

[0017] 2. Both the chassis assembly and the carriage assembly of this utility model are made of aluminum alloy. Because aluminum alloy is highly corrosion resistant, this utility model has a longer service life.

[0018] 3. Both the chassis assembly and the carriage assembly of this utility model are made of aluminum alloy. Since the surface of aluminum alloy is smooth and does not easily stick to materials, this utility model unloads goods more cleanly with a low residue rate.

[0019] 4. Both the chassis assembly and the carriage assembly of this utility model are made of aluminum alloy. Since aluminum alloy is recyclable and reusable, and is green and pollution-free, this utility model has high recycling value and high residual value.

[0020] 5. The side plate assembly of this utility model eliminates the transverse and longitudinal beams (i.e., unreinforced structure) of the traditional dump truck side plate, reducing the thickness of the side plate. At the same time, it limits the lower frame, upper frame and rear column of the side plate to aluminum alloy open mold material structure. Under the premise of unchanged external dimensions and guaranteed strength, it increases the effective volume of the box, increases the loading capacity and significantly improves economic benefits.

[0021] 6. This utility model further improves its strength by welding the bottom plate crossbeam and the bottom plate rear crossbeam to the side plate lower frame to form a frame structure.

[0022] 7. This utility model forms a frame structure by connecting the vertical ribs in the front plate cylinder to the bottom plate connecting plate, thereby dispersing the stress of the vertical ribs in the front plate cylinder.

[0023] 8. This utility model ensures stress transmission by aligning the vertical ribs in the front plate with the I-beams of the base frame. Attached Figure Description

[0043] In summary, this utility model mainly achieves the goal of minimizing weight and achieving ultimate lightweight design by using aluminum alloy for both the chassis assembly 1 and the carriage assembly 3, and by adjusting the specific structure of the chassis assembly 1 and the carriage assembly 3.

[0044] A more specific technical solution could be to weld the bottom plate crossbeam 3-4-2 and the bottom plate rear crossbeam 3-4-5 to the side plate lower frame 3-3-2 to form a frame structure, thereby further improving its strength.

[0045] Furthermore, the vertical rib 3-1-5 in the front plate cylinder is used to install the cylinder and can be connected to the bottom plate connecting plate 3-4-3 to form a frame structure, thereby dispersing the stress of the vertical rib 3-1-5 in the front plate cylinder.

[0046] Furthermore, the vertical reinforcement bars 3-1-4 in the front plate can be aligned with the I-beam 1-1 of the base frame to ensure stress transmission.
