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

Abstract

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. A dustproof scraper blade perpendicular to the stand column guide rail is fixed on the support, and the end of the dustproof scraper blade is closely attached to the surface of the stand column guide rail. The numerical value of the electrode electric conduction arm stand column can be accurately detected, the electrical characteristics of the working of an electrode inside the electric-arc furnace are grasped, the fluctuation of an arc current is reduced, the operating ratio of the production of the electric-arc furnace is improved, and a reliable basis and a means are provided.

[0003] During the production of industrial electric arc furnaces, linear displacement sensors and metal pull wire structures are used to detect the position of the electrode conductive arm column. In different production stages, with the continuous vibration of the electrode conductive arm column, the tension of the metal pull wire changes continuously. The repeatability of the linear displacement sensor is poor, resulting in a large data error in the position of the electrode conductive arm column, which cannot accurately reflect the position of the conductive arm
