The invention discloses a sleeve-type lifting device for hot-line work. The sleeve-type lifting device comprises a mobile vehicle, a vertical telescopic unit, a horizontal telescopic unit and an insulation jaw. The mobile vehicle plays the effects of bearing and moving. The vertical telescopic unit can ascend and descend in the vertical direction, and the horizontal telescopic unit can stretch and retract in the horizontal direction. The insulation jaw is used for bearing a dry ice jet cleaning device. The dry ice jet cleaning device is used for performing dry ice jet cleaning on a cleaning target. The sleeve-type lifting device is simple in structure, convenient to move and operate, high in working efficiency and capable of completing cleaning tasks at a specific occasion efficiently. In addition, the sleeve-type lifting device uses electric power and compressed air as power sources at the same time, key components are made of insulation materials, and therefore working stability of the device can be not disturbed and influenced by high potentials, and insulation safety can be guaranteed.
