Description
Technical Field
[0001] The utility model relates to the technical field of truck cargo boxes, in particular to a special-shaped wide-body lightweight cargo box for mining. Background Art
[0002] Wide-body dump trucks have been promoted and applied as the mainstream transportation tools for outsourcing stripping projects in small and medium-sized open-pit mines and large and extra-large open-pit mines due to their low price and high cost performance. Wide-body dump trucks, as the name implies, meet the purpose of increasing the vehicle's effective load by raising and widening its carriage. The cargo box of wide-body mining vehicles is used to carry materials in the mining area. The weight and loading and unloading efficiency of the cargo box will directly affect the use of wide-body mining vehicles.
[0003] The cargo box of a traditional wide-body dump truck for mining is a rectangular cargo box, and the connection between the main boards is mainly straight plate welding. This type of cargo box has a simple structure, but has poor unloading performance when transporting mud or materials with high viscosity. When unloading, materials are prone to stick to the corners of the cargo box. If not handled, over time, the materials stuck in the cargo box will increase the weight of the cargo box, reduce the actual load capacity, and reduce transportation efficiency.
[0004] In the prior art, wide-body dump truck cargo boxes for mining usually have a heating system added to the bottom to reduce the phenomenon of materials sticking to the inside of the cargo box. However, the installation of the heating system will increase the weight of the cargo box, and the processing and manufacturing steps are cumbersome, which will further increase the cost of cargo box manufacturing, which does not conform to the principle of reducing costs and increasing efficiency. In addition, the side panels of the existing cargo boxes will increase the structural strength and reliability of the side panels by adding reinforcing beams, which is costly and does not conform to the principle of reducing costs and increasing efficiency. Utility Model Content
[0005] In order to solve the technical problem in the prior art that the bottom heating system of the cargo box of a wide-body dump truck for mining and the reinforcing beams of the side panels increase the weight and cost of the cargo box, the utility model provides a special-shaped wide-body lightweight cargo box for mining.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A special-shaped wide-body lightweight cargo box for mining, comprising a front plate, a bottom plate and two side plates arranged opposite to each other, wherein the front plate is connected to the front ends of the two side plates, the bottom plate is connected to the bottoms of the two side plates, the side walls of the side plates are gradually bent and protruded toward the outside of the cargo box in the direction from the bottom to the middle, and the side walls of the side plates are gradually bent and retracted toward the inside of the cargo box in the direction from the middle to the top; the connection between the side plates and the bottom plate is an arc surface, and the arc surface protrudes toward the outside of the cargo box.
[0008] By adopting the above-mentioned structural scheme, the bending form of the side panel can effectively strengthen the structural strength of the side panel, reduce the side panel reinforcement beam, reduce costs, reduce the weight of the cargo box, and the actual carrying volume of materials is large. The bottom of the side panel adopts an arc transition design, which can improve the material pouring performance and reduce the adhesion of materials to the corners of the cargo box. There is no need to set up a heating system to reduce adhesion and reduce the weight of the cargo box. This application complies with the principle of reducing costs and increasing efficiency.

One end of the inclined beam corresponds to the position of the flat beam, and the other end is inclined downward.
[0014] The above structural solution is adopted to replace the traditional vertical arrangement of the front reinforcement beam. The force-bearing area of the present application is reduced, the impact force of the cargo on the front plate is smaller, the reliability of the front plate structure is improved, and costs are reduced and efficiency is increased.
