Full-automatic utility pole centralizer

The invention relates to a full-automatic utility pole centralizer comprising a hoop, a hydraulic mechanism, a length adjuster, a connecting shaft, a right hand thread screw, a left hand thread screw, a base, a mercury switch and an electric hydraulic pump. The hoop is connected with the hydraulic mechanism through the connecting shaft. The hydraulic mechanism and the right hand thread screw are welded together. The right hand thread screw and the left hand thread screw are screwed in two ends of the length adjuster, respectively. A limit stopper is arranged at the end of each of the screws screwed into the length adjuster. The other end of the left hand thread screw is connected with the base through the connecting shaft. The hydraulic mechanism is provided with a relief valve and a hydraulic joint. The electric hydraulic pump is connected with the hydraulic joint through a high-pressure rubber pipe. The mercury switch is parallelly attached to a utility pole and is connected with the electric hydraulic pump through a circuit. The full-automatic utility pole centralizer has the advantages that when tilting, the utility pole can be automatically centralized with no power outage; power supply reliability is ensured, work efficiency is improved, and risks caused by power outage are reduced.
