The invention relates to the field of dump trucks, and provides a mining vehicle which comprises a frame and a container arranged on the frame. The container bottom plate comprises at least two transverse supporting beams arranged in the width direction of the frame, and the transverse supporting beams are distributed in the length direction of the frame at intervals. The longitudinal supporting beams are distributed in the width direction of the frame at intervals, the longitudinal supporting beams and the transverse supporting beams are arranged in a crossed mode, and each longitudinal supporting beam is provided with a through hole allowing the corresponding transverse supporting beam to penetrate through, so that the transverse supporting beams are connected into the longitudinal supporting beams in a penetrating mode. By means of the arrangement, the transverse supporting beams and the longitudinal supporting beams are connected in a penetrating mode, the structural strength is high, the contact area of the connecting positions is increased, stress on the connecting positions of the transverse beams and the longitudinal beams can be dispersed through the through holes, and therefore stress on the welding positions of the transverse beams and the longitudinal beams is reduced, and the phenomenon that weld joints of traditional transverse beams and longitudinal beams crack is avoided; the shock resistance of the bottom plate can be greatly improved, the service life of a vehicle is effectively prolonged, and the maintenance cost of the vehicle is reduced.
本发明涉及自卸车领域,提供一种矿用车辆,包括车架、货箱,货箱设置在车架上。货箱底板包括:至少两个横向支撑梁,沿车架宽度方向设置,各个横向支撑梁沿车架长度方向间隔分布;至少两个纵向支撑梁,沿车架宽度方向间隔分布,纵向支撑梁和横向支撑梁交叉设置,各个纵向支撑梁均设有供横向支撑梁穿过的贯通孔,以使横向支撑梁贯穿连接于纵向支撑梁中。如此设置,若干横向支撑梁和纵向支撑梁采用贯穿式连接方式,其结构强度高,连接位置的接触面积增大,且通过贯通孔可将横纵梁连接处受力分散,从而降低横纵梁焊接处受力,避免出现传统横纵梁焊缝处开裂现象,能够大大提高底板的抗冲击性能,有效提升车辆使用寿命,降低车辆维护成本。
