Folding overhaul platform for high-current line of arc furnace

Abstract

The invention relates to a folding overhaul platform for a high-current line of an arc furnace, belonging to the technical field of metallurgy and iron and steel. The folding overhaul platform, which is used to overhaul a high-current power supply line, includes a fixed section overhaul corridor and a folding platform which are arranged on the two sides of the high-current power supply line. The fixed section overhaul corridor is fixedly connected with a supporting pillar, and a guide wheel is arranged at one end of the supporting pillar away from the fixed section overhaul corridor. One end of the folding platform is rotationally connected to the fixed section overhaul corridor, and the other end is fixed to the supporting pillar by a rope. A driving device is arranged on the fixed section overhaul corridor. One end of the folding platform away from the fixed section overhaul corridor is connected with a transmission line body. The transmission line body is connected to the driving device after bypassing the guide wheel. By arranging the folding platform at the front end of the fixed section overhaul corridor, the problem of smelting production interruption caused by regular maintenance is solved, the assistance time of overhaul is reduced, and the work efficiency of overhaul is improved.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and iron and steel, and relates to a foldable inspection platform for high-current lines of electric arc furnaces. Background technique [0002] When the existing steelmaking electric arc furnace and ladle refining furnace are in production, the working current of the high-current power supply line is tens of thousands of amperes. The magnetic field induction and electromagnetic vibration force generated by the large-current line will cause the power supply line and the surrounding various Metal objects are heated by induction, and electromagnetic vibration force makes bolts and other joints loose due to vibration. Water leakage often occurs due to the loosening of cooling water pipe clamps caused by vibration. [0003] Various conductive metal dusts will accumulate on the high-current lines during smelting, which will cause grounding short circuit of the power supply lines and interfere with n...
