Intelligent control system and method for electric furnace charging crane

Abstract

The invention discloses an intelligent control system and method for an electric furnace charging crane. Main and secondary lifting height detection equipment are arranged on main and secondary lifting mechanisms. Electronic anti-swing equipment, a large vehicle gray bus and a main small vehicle gray bus are added. A cab camera is added. Material basket coordinate scanners, main hook recognizing cameras, material pit panoramic cameras and a secondary hook recognizing camera are arranged corresponding to material pits. A discharging position panoramic camera is arranged corresponding to an electric furnace. Wireless AP (Access Point) data equipment and video equipment are arranged at two ends of a crane running interval respectively. A wireless communication client and a wireless video client are arranged at two ends of a large vehicle end beam. Fireproof cotton is arranged on the main small vehicle gray bus. Detection means for carrier lifting, waste steel discharging and carrier resetting of the electric furnace charging crane are added, detection equipment on a crane body is screened, an effective protection means is adopted in an auxiliary manner, and remote video operation equipment is added, so that intelligent running of the electric furnace crane is realized. Compared with the unmanned running scheme of a conventional crane, artificial monitoring, intelligent detection and automatic running schemes are adopted.

Description

technical field [0001] The invention belongs to the field of intelligent control systems for cranes, in particular to an intelligent control system and a control method for electric furnace feeding cranes. Background technique [0002] In the electric furnace factory, the raw material for electric furnace steelmaking is scrap steel, and the feeding equipment is a feeding crane, which has several more mechanisms than conventional cranes, and because it belongs to production equipment, the electric control system usually adopts a mutual backup redundant system. The crane plays a vital role in the electric furnace steelmaking system. Currently, the electric furnace steelmaking system is operated under manual control. Since scrap steel is smelted in electric furnace steelmaking, the quality of steelmaking is changed by adding special impurities and special steel, and steel slag is removed by adding lime, so in the whole smelting process, it is necessary to open the furnace many ...

AI Technical Summary

Problems solved by technology

However, the electric furnace factory has been unable to carry out unmanned promotion due to many reasons such as the particularity of the equipment, the complexity of the process, and the harsh production environment.

The difficulty of its unmanned implementation is that firstly, the crane equipment has multiple mechanisms that need to be automatically controlled, while the automatic control of conventional cranes only needs to control three mechanisms; secondly, the crane equipment needs to lift scrap steel for furnace roof Feeding, and when feeding, the fire will spread to the top of the crane body. At this time, the equipment on the crane body will be roasted or burned by the flame, which has very strict requirements on the high temperature resistance of the equipment; the third is the feeding process. Complexity. Compared with the process flow of conventional cranes that only need to move the load from A to B, the process flow of the electric furnace charging crane is much more complicated; the fourth is the carrier lifting, scrap unloading and carrier return of the electric furnace charging crane. There is no effective detection method for automation
