The invention relates to the technical field of aerial work equipment, in particular to a traveling chassis capable of expanding axles in situ and an aerial work platform, the traveling chassis comprises a main frame, a wheel assembly, a front axle unit and a rear axle unit, and each axle unit comprises a left half-axle structure and a right half-axle structure which are symmetrically arranged and rotationally connected to the main frame; the end, away from the main frame, of each half-bridge structure is rotationally connected with a wheel assembly. The axle unit further comprises a first pushing device and a second pushing device, and the first pushing device can push the half-axle structure to swing relative to the main frame in the horizontal direction. The second pushing device can push the wheel assembly to rotate relative to the half-bridge structure in the horizontal direction till the rolling direction of the wheel assembly is generally consistent with the swinging tangential direction of the half-bridge structure. The wheel assemblies are pushed to rotate until the rolling direction of the wheel assemblies is consistent with the swinging tangential direction of the half-bridge structure, and the wheel assemblies synchronously roll and advance in the swinging process, so that in-situ bridge expansion of the driving chassis is realized.

    本发明涉及高空作业设备技术领域,具体涉及一种能够原地扩桥的行驶底盘及高空作业平台,行驶底盘包括主车架、车轮组件以及前后两个车桥单元,车桥单元包括左右两个对称设置且分别转动连接在主车架上的半桥结构,每个半桥结构上远离主车架的一端都转动连接有车轮组件;车桥单元还包括第一推动装置和第二推动装置,第一推动装置能够推动半桥结构在水平方向上相对于主车架摆动,第二推动装置能够推动车轮组件在水平方向上相对于半桥结构转动至车轮组件的滚动方向与半桥结构的摆动切向大体一致。通过推动车轮组件并使其转动至自身滚动方向与半桥结构的摆动切向一致,在摆动过程中车轮组件同步滚动行进,从而实现所述行驶底盘的原地扩桥。
