The invention relates to the technical field of operation machinery, and provides a telescopic chassis and an operation machine.The telescopic chassis comprises a pair of main beams, a pair of auxiliary beams and a pair of supporting rods, the middle beam is arranged between the pair of main beams; the lengthened beam assembly comprises a pair of inner lengthened beams, the pair of inner lengthened beams are correspondingly connected with the ends of the main beams respectively, and the pair of inner lengthened beams are located on the same side of the middle beam. The inner lengthened beam can be switched between a contraction state and an expansion state; in the contraction state, the inner lengthened beams are perpendicular to the main beam, and the free ends of the pair of inner lengthened beams are arranged in a staggered mode in the vertical direction. In the unfolded state, the inner lengthened beams extend outwards from the ends of the main beams respectively. The pair of complementary beams is used for compensating the height of the free end of the inner lengthened beam in the unfolded state. On the basis of the original length size, the connecting mode that the free ends of the inner lengthened beams are vertically staggered is adopted, the length of the inner lengthened beams is increased, and the requirement for a larger gauge is met.

    本发明涉及作业机械技术领域,提供一种伸缩式底盘及作业机械,伸缩式底盘包括:一对主梁,一端设置有加长梁组件;中间梁,设置于一对主梁之间;加长梁组件包括:一对内加长梁,一对内加长梁分别对应与主梁的端部连接,且一对内加长梁位于中间梁的同一侧;内加长梁能够在收缩状态和展开状态下切换;在收缩状态,内加长梁与主梁垂直,且一对内加长梁的自由端在竖直方向上错位布置;在展开状态,内加长梁分别自主梁的端部向外延伸;一对互补梁,用于在展开状态下对内加长梁的自由端的高度补偿。本发明在原来长度尺寸的基础上,采用内加长梁的自由端上下错位的连接方式,增加内加长梁的长度,达到更大的轨距要求。
