Detailed Description

The utility model will be better explained by the following detailed description of the embodiments with reference to the drawings. References herein to terms such as "upper", "lower", "inner" and "outer" refer to the orientation of FIG. 1. The position of the bar-shaped side plate 11 with respect to the arc-shaped side plate 12 is defined as "up"; the position of the first wear layer 20 relative to the first wear plate 10 is defined as "inner".

As described above, the inventors have found in studies on a vehicle body and a vehicle that, in order to carry an object, the vehicle may include a vehicle body through which the object can be carried. In the mining process, the heavy-load mining electric dumper can be applied to surface mining, and hybrid power electric vehicles can also be used. Mining vehicles may carry 400 tons of objects or even heavier. When the bearing weight is increased, the wear resistance requirement of the carriage can be correspondingly increased. During loading, transporting and unloading objects, collisions and friction may occur between the objects and the truck bed, causing damage to the truck bed and a reduction in the service life of the truck bed. The plane plate can be used as a wear-resistant plate to be paved on the bottom plate of the carriage so as to reduce the abrasion of the bottom plate. However, the wear plate may be damaged after long-term contact with the carried object, thereby causing wear of the bottom plate below the wear plate and the carried object due to contact. Wear plates are typically provided for the bottom plate, but not for the side plates, and therefore, damage to the side plates can occur, thereby affecting the service life of the truck bed. In addition, the solution of thickening the wear plate will increase the cost of the truck bed.
