Abstract
In view of the simple determination of the safety value of the wire rope tension of the pitching mechanism in the scraper reclaimer,it is impossible to comprehensively and accurately evaluate the operation safety factor of the scraper reclaimer,the common pitching angles and their corresponding tension values were regressed,the curve regression equations of the pitching angles and the corresponding tension of each angle were calculated,and the fitting degree and significance of the curve were detected.Based on this equation,the mathematical model of wire rope pitching tension protection was established.By setting the theoretical wire rope tension protection curve of the reclaimer in no-load state or heavy-load state as a safety detection program,and combining with the operation logic of the control software,the start-up,pitching and traveling of the equipment are restricted to ensure the operation safety of equipment.关键词
