Automatic detection device of industrial electric arc furnace electrode conduction arm column position

The utility model relates to an automatic detection device of an industrial electric arc furnace electrode conduction arm column position. A traditional electric arc furnace uses a line displacement sensor and a metal traction line structure to detect an electrode conduction arm column position and a data error of the position is large. According to the utility model, a fixing center shaft seat which is fixed below a column guide wheel platform is arranged; a lower portion is in rotation connection with a movable balance seat through a movable shaft; a counterweight block is fixed on the movable balance seat; a support which is extended downwardly is fixed on the movable balance seat and the movable balance seat is connected with a rotary encoder fixing seat, wherein a rotary encoder is fixed on the rotary encoder fixing seat; the rotary encoder is connected with a measurement guide wheel through a fastening pin and is stuck tightly on a column guide rail surface; a dustproof scraper plate which is vertical t
