The invention discloses a container rear tail door, a container, a dumper and a manufacturing method. The container rear tail door comprises a door plate, a connecting arm, an upper cross beam, a middle cross beam and a lower cross beam. Connecting arms are arranged at the left and right ends of the outer side surface of the door plate. The connecting arm is a 7-shaped arm plate, the lower end is close to the lower edge of the door plate, and the upper end exceeds the upper edge of the door plate. An upper beam, a middle beam and a lower beam are clamped between the two connecting arms, the upper beam abuts against the upper edge of the door plate, the middle beam abuts against the middle area of the door plate, and the lower beam abuts against the lower edge of the door plate. The heights of the connecting arms are gradually reduced from top to bottom, and the heights of the sections of the upper cross beam, the middle cross beam and the lower cross beam are correspondingly reduced in sequence. The upper end of the connecting arm is hinged to the tail of the container so that the rear tail door can rotate relative to the container. The rear tail door is simple in structure, small in welding amount, easy to manufacture, high in bearing capacity, concentrated in stress, small in welding stress and capable of adapting to impact force and alternating stress in the operation process, cracking is reduced, and production efficiency is improved.
本发明公开了一种货箱后尾门、货箱、自卸车及制造方法,包括门板、连接臂、上横梁、中横梁、下横梁。在门板外侧面的左右两端各设有连接臂。连接臂为7字形臂板,下端靠近门板下边沿,上端超出门板上边沿一段。两个连接臂间夹有上横梁、中横梁、下横梁,上横梁紧靠在门板上边沿,中横梁紧贴在门板中间区域,下横梁紧贴在门板下边沿。连接臂高度从上至下为逐渐缩小,上横梁、中横梁、下横梁的截面高度相应依次缩小。连接臂上端与货箱尾部铰接连接,以便后尾门相对货箱转动。本发明公开的后尾门,结构简单、焊接量少、制造容易,并且承载高,应力集中和焊接应力少,能够适应作业过程中的冲击力及交变应力,减少开裂发生,提升生产效率。
