AI Technical Summary
Technical Problem
The impact of falling ore on the cargo box floor caused cracks at the welds of the cross and longitudinal beams, affecting the vehicle's service life.
Method used
The transverse and longitudinal support beams are connected by a through-hole structure, which increases the contact area and strength, distributes the stress, and prevents cracking at the weld.
Benefits of technology
It improves the impact resistance of the cargo box floor, extends the service life of the vehicle, and reduces maintenance costs.

Abstract
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。
