The invention discloses a rigid frame and a dump truck, and relates to the technical field of engineering machinery. The longitudinal beams are sequentially provided with bumper assemblies, front suspension supports, wing supports, gantry beams and connecting rod supports from front to back, wherein the bumper assemblies wrap the front ends of the longitudinal beams, the front suspension supports are installed on the two longitudinal beams in a bilateral symmetry mode, the wing supports are installed on the front suspension supports, the gantry beams are installed on the two front suspension supports, and the connecting rod supports are arranged at the bottoms of the two longitudinal beams. The tail beam is arranged at the tail end of the longitudinal beam; and the hinged support is arranged on the tail beam. Parts such as a bumper assembly of the frame which have great influence on transportation efficiency are changed into assembled structures, and the problems that in the prior art, a traditional rigid frame needs to be transported integrally and cannot be disassembled, and the transportation cost is high are solved; in addition, a welding structure is poor in interchangeability, once the frame goes wrong, the whole assembly and even the whole frame can be replaced, and unnecessary maintenance cost is caused.

    本发明公开了一种刚性车架及自卸车,涉及工程机械技术领域,车架整体包括:左右对称平行设置的纵梁,所述纵梁从前到后依次设有包裹在所述纵梁前端的保险杠总成、左右对称安装在两所述纵梁上的前悬支座、所述前悬支座上安装的翼部支座、安装于两所述前悬支座上的龙门粱、两所述纵梁底部的连杆支座、所述纵梁末端安装的尾粱和所述尾粱上安装的铰接支座。本发明将车架的保险杠总成等对运输效率影响较大的部件更改为装配式结构,解决了现有技术中出现的传统的刚性车架需整体运输,不能拆卸,运输成本高;另外焊接结构存在互换性差,一旦车架出现问题会导致整个组件甚至整个车架进行更换,造成不必要的维修成本的问题。
