Abstract
Description
Technical Field
[0001] The utility model belongs to the field of mining dump trucks, and in particular relates to a self-cleaning carriage of an ultra-large mining dump truck. Background Art
[0002] Mining dump trucks are off-road dump trucks, which are used to transport coal, sand and gravel in off-road field sites, such as large open-pit mines and water conservancy projects. Most of the existing super-large mining truck carriages are directly welded from two pieces of carriage plates, which is difficult to process. The structural strength of the carriage plate cannot be guaranteed when using the two-piece carriage plate welding technology. There are huge safety hazards in the process of transporting materials, which may cause casualties and economic losses in serious cases.
[0003] Ordinary dump trucks are often used in engineering projects to transport concrete, clay and other materials with strong adhesion. The loading compartment of an ordinary dump truck is usually rectangular. During unloading, some concrete, clay and other materials will adhere to the bottom plate of the dump truck compartment, the right-angle intersection of the front fender and other positions. After unloading, it is necessary to use manual shoveling to remove the adhered materials, which not only wastes man-hours but also increases construction costs. Utility Model Content
[0004] The utility model aims to provide a self-cleaning carriage of an ultra-large mining dump truck, which can effectively reduce the processing technology of the carriage, enhance the strength and rigidity of the weld, and clean the residual materials attached to the carriage.
