Description

Technical Field

[0001] The utility model relates to the field of mining machinery, in particular to a dump truck cargo compartment mechanism and a dump truck with the cargo compartment mechanism. Background Art

[0002] Currently, most domestic mines utilize electric dump trucks, which are very large in size, weight, and payload. The cargo box is one of the major load-bearing components of an electric dump truck, determining its payload capacity. Furthermore, the complex, rugged, and bumpy roads in mining areas place even more stringent demands on the cargo box. Furthermore, mining environments are generally harsh, with remote and isolated locations, making maintenance and after-sales services difficult. Therefore, optimizing the design of the cargo box, a key component of dump trucks, is crucial.

[0003] Electric dump truck cargo bodies are primarily categorized as square and U-shaped. Square bodies feature a flat, square main structure reinforced with channel beams. The floor, front, side, and front guard panels are heavily ribbed to meet the overall rigidity requirements. However, the disadvantages of this traditional cargo body include its heavy weight, reduced elastic deformation, low impact resistance, ineffective chassis protection, low fatigue strength, and the tendency for sticky materials to adhere to the floor during unloading. U-shaped bodies often utilize the elastically deformable dump truck body structure. The floor, front, and front guard panels utilize curved surfaces instead of traditional flat surfaces. This reduces ribs to reduce weight and enable the transport of larger loads within the maximum allowable load. This curved surface increases resistance to collisions and impacts and provides maximum structural flexibility, preventing stress concentration that could damage the cargo body. It also increases unloading speed and improves transportation efficiency.

[0004] However, the current width of cargo compartment floors generally exceeds 2 meters, requiring custom fabrication. This is costly and requires long lead times. Furthermore, during unloading, friction between cargo and the floor causes significant wear and tear on the rear end of the floor, shortening the lifespan of the compartment and increasing operating and maintenance costs.

[0007] Furthermore, the bottom plate includes a main plate and an auxiliary plate, a portion of the auxiliary plate overlaps with the main plate and is fixed to each other by welding, and another portion of the auxiliary plate forms an angle with the main plate in the range of 120°-160°.

[0008] Furthermore, both the main plate and the auxiliary plate are bent into a curved shape, the main plate is bent with 2-4 knives, and the auxiliary plate is bent with 7-9 knives.

[0009] Furthermore, the compartment plate assembly also includes a first support plate and a second support plate welded to the bottom of the main plate. The length directions of the first support plate and the second support plate are consistent, the second support plate is closer to the auxiliary plate than the first support plate, and an avoidance gap is formed between one end of the second support plate and the auxiliary plate to avoid the weld between the main plate and the auxiliary plate.

At the same time, the bottom plate is bent 10 times, bending the plate into a nearly U-shape. The number of bending cuts in the cargo compartment is relatively small, which greatly reduces the processing cost and difficulty of the cargo compartment. In a further embodiment, the number of bending knives of the main plate is preferably 2, and the number of bending knives of the auxiliary plate is preferably 8.

The two compartment panel assemblies are welded from one side of the bottom panel 5 by welding, so that the two compartment panels are combined to form a cargo compartment body with an opening on one side.

[0028] In order to protect the bottom plate of the cargo compartment, the panel assembly further comprises a pressing plate 4 for shielding the welding seam formed on the bottom plate 5 when the two sets of panel assemblies are connected by welding, and a protection plate 6 for preventing the bottom plate from being worn out, which is arranged on the side of the bottom plate away from the front plate and connected with the bottom plate by plug welding or circumferential welding, thereby prolonging the service life of the cargo compartment and reducing the replacement cost.
