The invention discloses a multi-platform foldable tunnel maintenance operation device which comprises a balancing weight, a telescopic arm, a first operation platform and a variable-amplitude operation mechanism. The telescopic arm comprises a basic arm and an unfolding arm; one end of the basic arm is connected with the balancing weight; the other end of the basic arm is slidably connected with the unfolding arm; a first rotating mechanism is arranged at the bottom of the basic arm; the free end of the unfolding arm is fixedly connected with the variable-amplitude operation mechanism; and theinner side of the free end of the unfolding arm is rotatably connected with one end of the first operation platform through a second rotating mechanism, so that the first operation platform can be unfolded in the horizontal direction, and the variable-amplitude operation mechanism can be unfolded in the vertical direction; in the folded state, the length direction of the first operation platformand the variable-amplitude operation mechanism is the same as the direction of the telescopic arm; and the variable-amplitude operation mechanism comprises a plurality of operation platforms which aredistributed in a stepped mode when being unfolded. The device is large in operation coverage, large in bearing capacity, capable of achieving half-section simultaneous operation, high in operation efficiency, high in safety, small in carriage folding area, simple in structure and low in cost.
