The invention discloses a carriage for a dump truck or a dump semitrailer, which comprises a bottom plate, side plates, a front plate and a rear plate, and is characterized in that the bottom plate isprovided with a sinking part, and the sinking part is positioned on the median line of the bottom plate and extends along the length direction of the bottom plate; hooking and folding parts are arranged on the lower sides of the side plates, and after the bottom plate and the side plates are welded, the hooking and folding parts are closed by the bottom plate to form a hollow beam so as to reinforce and protect a welding part. The sinking part is designed, so that loaded materials automatically move towards the middle, and the purposes of automatically centering and lowering the gravity center are achieved; and after the side plates and the bottom plate are welded and fixed, the hooking parts and the bottom plate form hollow longitudinal beams, so that the overall structural strength of the carriage is improved, particularly, the welding positions of the bottom plate and the side plates are reinforced and protected, the situation that the welding positions are broken is reduced, and the anti-swelling capacity of the side plates can be improved to a certain extent.

    本发明公开了一种用于自卸车或自卸半挂车的车厢,包括底板、侧板、前板和后板,其中:所述底板设置有下沉部,下沉部位于底板的中位线上,且沿底板的长度方向伸延;所述侧板的下侧设置有勾折部,在底板与侧板焊接后,勾折部被底板封闭构成中空梁以加强和保护焊接部位。本发明通过设计下沉部使得装载的物料自动往中间走,达到自动找中和降低重心的目的;且侧板和底板焊接固定后,勾折部和底板构成中空的纵梁,提高了车厢的整体结构强度,特别是对底板与侧板焊接的位置起到加强和保护的作用,减少焊接部位破裂的情况发生,且能够在一定程度上提高侧板的防涨能力。
