The invention discloses a mining dump truck bottom protection plate and a mining dump truck. The mining dump truck bottom protection plate comprises a front protection plate, a rear protection plate, a front fixing seat and a rear fixing seat. The front portion of the front protection plate penetrates into the left lug plate and the right lug plate through fasteners to be fixed to the left front fixing seat and the right front fixing seat respectively, the rear protection plate penetrates into fixing holes in the bent portion through fasteners to fix the rear side of the rear protection plate to the left rear fixing seat and the right rear fixing seat, a pin shaft penetrates into the connecting holes of the connecting supports of the front protection plate and the rear protection plate after the connecting holes are aligned, and a gasket and a cotter pin are additionally arranged for fixing. By means of the mode, the side protection capacity and the rear protection capacity of the bottom protection plate can be enhanced, an intercooler and an engine are better protected, and meanwhile maintenance convenience is guaranteed. In order to guarantee the air suction capacity of the intercooler, the front side protection plate adopts a conventional grid structure, but the structural strength of the fixing seat is enhanced through the optimized design of the fixing seat structure of the triangular side plates and the bent parts. Handles are designed on the left and right sides of the rear protection plate, so that the risk caused by lifting right below the bottom protection plate by people during disassembly and assembly of the bottom protection plate is avoided.

    本发明公开了一种矿用自卸车底护板及矿用自卸车,包括前护板、后护板及前后四个固定座。前护板前部通过紧固件分别穿入左右耳板固定在左、右前固定座上,后护板通过紧固件穿入折弯部上的固定孔后将后侧固定在左、右后固定座上,前、后护板的连接支座的连接孔对齐后将销轴穿入,加装垫片和开口销固定。通过上述方式,本发明能够增强底护板的侧防护及后部防护能力,更好的保护中冷器和发动机的同时,保证了维保的便利性。前侧护板为保证中冷器的吸风能力,采用了常规的栅格结构,但三角形侧板+折弯部的固定座结构优化设计增强了固定座的结构强度。后护板左右设计有把手,避免底护板拆装时需要人在底护板正下方托举带来的风险。
