Description

Technical Field

[0001] The utility model relates to the technical field of mining dump trucks, in particular to a bottom plate structure of a mining dump truck. Background Art

[0002] Mining dump trucks are only used in limited mining areas. There is no restriction on the vehicle's external dimensions. In order to increase the transport volume of each trip, the vehicle compartment volume is increased as much as possible, and the vehicle's external dimensions are widened and heightened. They cannot be driven on roads. They are mainly used for mining and engineering construction. When loading, large rocks fall into the compartment, and the impact force is transmitted to the compartment chassis, subframe and main engine longitudinal beams. Long-term use will cause these components to reach fatigue limits and be damaged. Therefore, a buffer structure such as a rubber pad is set in the floor structure of the mining dump truck.

[0003] For example, the Chinese utility model patent with authorization announcement number CN201833929U discloses a mining dump truck, specifically a mining dump truck floor structure. It includes a vehicle floor, characterized in that a rubber mat is laid on the vehicle floor, and a steel plate is laid on the rubber mat. This utility model has a simple structure and is easy to implement. When a mining dump truck is loaded with large rocks, the rubber mat between the two layers of steel plates acts as a buffer, thereby reducing the impact force acting on the vehicle floor frame, subframe, and mainframe longitudinal beams, reducing fatigue in these components and thereby extending the service life of the dump truck.

[0004] However, the existing bottom plate structure of a mining dump truck needs to be improved in strength and is inconvenient to disassemble and assemble. Therefore, we propose a bottom plate structure of a mining dump truck to solve the above problems. Utility Model Content
