Device for automatically detecting position of industrial electric-arc furnace electrode electric conduction arm stand column

The invention relates to a device for automatically detecting the position of an industrial electric-arc furnace electrode electric conduction arm stand column. A linear displacement sensor and a metal pull wire structure are utilized for detecting the position of an electrode electric conduction arm stand column of a traditional electric arc furnace, and the data error of the position is large. A fixed center shaft base is fixed on the lower portion of a stand column guide pulley platform, the lower portion of the fixed center shaft base is rotatably connected with a movable balance base through a movable shaft, and a balance weight is fixed on the movable balance base. A support extending downwards is fixed on the movable balance base and is connected with a rotating encoder fixing base, and a rotating encoder is fixed to the rotating encoder fixing base. The rotating encoder is connected with a measuring guide pulley through a locking pin and is closely attached to the surface of a stand column guide rail.
