Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mining dump trucks, in particular to a mining dump truck cargo box unloading distance increasing structure and a dump truck cargo box. Background Art
[0002] A mining dump truck is a heavy-duty off-road dump truck used in open-pit mines to transport ore. It generally has a load capacity of more than 20 tons. Due to its maneuverability, strong climbing ability and small turning radius, it is widely used in various mines with complex and scattered mining terrain.
[0003] The main differences in wheelbase and cargo box are found in the current market for dump trucks. To meet customer requirements for larger cargo boxes, this is often achieved by simply lengthening the vehicle's wheelbase or extending the rear overhang. This results in an overload on the front axle when fully loaded, while moving the cargo box rearward can lead to an excessively long rear overhang, resulting in insufficient strength.
[0004] A common problem is that extending the cargo box requires a longer wheelbase, which places too much weight on the front axle. If the cargo box is moved rearward, the rear overhang becomes too long, affecting strength and reducing ground clearance between the rear door and the vehicle when the box is lifted. Currently, some mining dump trucks have shortened rear overhangs to improve strength, resulting in a shorter lead distance during unloading, making it easier for materials to damage the rear compartment. Utility Model Content
[0005] In view of the defects in the existing technology, the utility model provides a mining dump truck cargo box unloading distance extension structure and a dump truck cargo box to solve the problem that the mining dump truck has a short rear overhang, a short guiding distance during unloading, and materials easily damage the rear tail parts of the car body.

[0013] It can be seen from the above technical solution that the structural strength of the unloading distance-increasing structure of the cargo box of the mining dump truck provided by the utility model is improved by arranging the reinforcing brace, thereby improving the reliability.
[0014] Optionally, the protective plate includes an integrally formed vertical section, an inclined section and a horizontal section, the vertical section is located on the outside of the cargo box side panel, the inclined section adapts to the oblique angle setting of the bottom of the cargo box tail panel, and the horizontal section is arranged on the second plane section.
