Aerial work lifting device

The high-altitude operation lifting device comprises a first guide rail, a climbing mechanism and a driving mechanism, the first guide rail can be connected with a wire in a power transmission line, and the guiding direction of the first guide rail intersects with the length direction of the wire; the climbing mechanism is arranged on the first guide rail and can move in the guiding direction of the first guide rail. The driving mechanism comprises a power part and a first transmission part, the power part is connected with the first transmission part, the first transmission part is connected with the climbing mechanism and used for driving the climbing mechanism to move on the first guide rail, and the first transmission part has a locking function. Thus, when the power part cannot provide power for the climbing mechanism due to faults or power failure, the climbing mechanism can still be stably locked on the first guide rail, the climbing mechanism can be effectively prevented from falling off from the firs
