Movable operation platform

The invention provides a movable operating platform which comprises a platform body and a walking assembly, the walking assembly comprises a first side walking device and a second side walking device, a first connecting arm and a second connecting arm are rotationally connected to the platform body, and the rotating axis of the first connecting arm and the rotating axis of the second connecting arm are both arranged in the vertical direction; the first bearing and the second bearing are used for advancing on a bottom plate of a main longitudinal beam in the longitudinal direction. The end, connected with the first bearing, of the first connecting arm and the end, connected with the second bearing, of the second connecting arm are oppositely arranged in the transverse direction. The operating platform can be driven by chain guide hoists and the like, so that the platform body longitudinally moves forwards on the bottom plate of the main longitudinal beam, blocking of structures such as stiffening ribs on the m
