The invention provides an engineering vehicle walking device capable of crossing obstacles, which belongs to the technical field of engineering vehicles and comprises a front wheel assembly and a rear wheel assembly which are symmetrically arranged and have the same structure, the front wheel assembly comprises a control assembly and two walking frame units connected with each other. Each walking frame unit comprises a main frame plate, a transmission assembly and two movable walking wheel assemblies; according to the movable walking wheel assembly, a rack is fixedly arranged at the top of a main frame plate; a gear and a moving assembly; the moving assembly is slidably arranged on one side of the main frame plate, and the gear is rotatably arranged on the moving assembly and engaged with the rack; the gear rotates to drive the moving assembly to move in the advancing direction. The lifting assembly is arranged on the moving assembly; a moving plate is arranged on the lifting assembly and driven by the lifting assembly to ascend and descend. A joint bearing is arranged on the movable plate; a wheel shaft of the wheel is fixed with an inner ring of the knuckle bearing; a control shaft is fixedly arranged at the top of the outer ring of the knuckle bearing at the front end; the control shaft is in transmission fit with the control assembly through the transmission assembly. The control assembly drives the two control shafts to rotate synchronously and drives the two wheels at the front end to swing by the same amplitude. According to the engineering vehicle walking device, crossing of large obstacles is achieved, the overall stability is good, and control is easy.
