In the above-mentioned hoisting device for maintenance of power transmission lines, the suspension wall and the support rod are movably connected, that is, an upper bearing is arranged between the suspension wall and the support rod, the outer ring of the upper bearing is fixedly connected to the support rod, and the inner ring of the upper bearing is fixedly connected to the connecting shaft. A locking bolt is arranged on the supporting rod at the lower part of the upper bearing, and the locking bolt passes through the supporting rod to contact with the connecting shaft. the

In the aforementioned hoisting device for maintenance of transmission lines, the support rod is formed by combining and fixing multiple support rod assemblies, and the bearing is arranged on the top support rod assembly. the

In the lifting device for transmission line maintenance, a support arm is further provided between the boom and the support rod, and a lower bearing is further provided between the support arm and the top support rod assembly, and the inner ring of the lower bearing is fixedly connected to the top support rod assembly. The support arm is fixed on the outer ring of the lower bearing. the

The above-mentioned hoisting device for maintenance of transmission lines is provided with at least two pulleys at different positions in the horizontal direction on the boom. the

By adopting the above-mentioned technical scheme, the utility model has the following advantages: the power tool that needs to be hoisted is hung on the hook of the utility model, since the steel wire rope arranged on the hook goes around the pulley on the boom and the pulley and is fixed on the base On the roller, start the reduction motor connected on the roller shaft, and the steel wire rope can be driven to lift the tool upwards, which is convenient for lifting the power tool. At the same time, an upper bearing is provided between the top of the support rod and the boom, and a lower bearing is provided between the upper part of the support rod and the support arm to facilitate the rotation direction of the boom according to the specific working conditions, and the multi-section support rod assembly can adapt to different heights For maintenance operations, multiple pulleys are set on the boom, and the distance between the hook and the support rod can be adjusted by adjusting the wire rope to go around different pulleys and passing wheels, so as to adapt to the hoisting work of power tools in different directions. the
