Abstract
Description
Technical Field
[0001] The utility model relates to the field of dump trucks, in particular to a dump truck cargo box. Background Art
[0002] Off-highway mining dump trucks, as the core transportation tools in mines and large-scale civil engineering projects, are designed for specific operating environments such as open-pit mines, earthwork stripping and ore transportation. They not only bear the heavy task of short-distance transportation, but also frequently travel between the mining point and the unloading point, and have high adaptability and durability.
[0003] In a mining dump truck, the function of the carriage is to provide loading space for materials. Among them, the rectangular (square) carriage has a larger loading volume and stronger functionality. It can not only carry sand and gravel, mining, but also some goods that can be loaded by ordinary railing carriages. However, since mining dump trucks often need to work in harsh environments, such as steep slopes and bumpy roads, the design of the carriage must fully consider the impact and collision of the goods. In order to ensure the strength and durability of the carriage, its materials are thicker and the structure is more complex. The weight of the carriage accounts for about 15%-25% of the total vehicle mass.
[0004] It can be seen that under the current demand and trend of lightweighting, reducing the weight of mining truck cargo boxes is an effective way to save costs and increase transportation capacity. Summary of the invention
[0005] Aiming at the problem that the cargo box of the current mining dump truck is heavy, the utility model provides a cargo box of the dump truck.
[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a dump truck cargo box, including a bottom plate, and side upright plates are arranged on both sides of the top surface of the bottom plate, the bottom plate includes a middle bottom plate and two side bottom plates, the side bottom plates are arranged on both sides of the middle bottom plate, the side upright plates are fixedly connected to the side edges of the side bottom plates away from the middle bottom plate, and the thickness of the side bottom plates is less than the thickness of the middle bottom plate. According to the characteristics of the loading process, the cargo box adopts a thickened bottom plate in the middle part of the cargo box that is subjected to greater impact from dumped goods, and the two sides are mainly rolling goods with less impact, and the thickness of the bottom plate is reduced here, and the weight reduction effect is achieved through reasonable thickness distribution, thereby improving the loading capacity.
[0007] Preferably, the bottom surface of the side bottom plate is flush with the bottom surface of the middle bottom plate, and the top surface of the side bottom plate is lower than the top surface of the middle bottom plate, so that the top surface of the bottom plate forms a complete plane, which is convenient for dumping goods and avoids small stones from getting stuck.
[0008] Preferably, the thickness of the midsole plate is 20-25 mm.
[0009] Preferably, the midsole plate and the side bottom plates are both made of NM400 material.
[0010] Preferably, the midsole plate comprises two midsole units, the two midsole units are connected to each other, and the joint between the two midsole units is also covered with a connecting plate. The midsole plate adopts a splicing structure, which is easy to manufacture.
[0011] Preferably, a side oblique strip is provided at the joint between the side bottom plate and the side vertical plate, and a set of opposite sides of the side oblique strip is respectively connected to the side vertical plate and the side bottom plate, so as to cover the right-angle turning area, improve the strength and avoid stone jamming.
[0012] Preferably, it further comprises a front plate, the bottom edge of the front plate is connected to the front side edge of the bottom plate, the two side edges of the front plate are respectively connected to the front side edges of the two side vertical plates; a front oblique strip is provided between the front plate and the bottom plate.
[0013] It can be seen from the above technical scheme that the advantages of the utility model are that, according to the characteristics of cargo loading and unloading, this scheme adopts thick plates in the middle area where the impact of dumping is large, and thin plates are used in the areas on both sides where stones slide down. By reasonably setting the thickness of the bottom plate, the weight of the cargo box is reduced while ensuring the functional strength, thereby improving the load-bearing capacity; through the design of the panel structure, the jamming of small stones is reduced, and dumping is cleaner.
