Analysis And Research On Safety Braking System Of Metallurgical Electric Hoist Lifting

Electric hoists play an important role in the metallurgical industry due to their excellent performance,simple structure,and reliable operation.In metallurgical applications,due to the high temperature,high corrosion,and frequent starting of the environment,the lifting mechanism of electric hoists is prone to various failures,which can cause major safety accidents in severe cases.Therefore,it is necessary to conduct in-depth research on the safety braking system of metallurgical electric hoists and improve the safety and reliability of the lifting braking system.This project is based on the safety and reliability of the lifting brake system,analyzes the configuration strategy and reasonable plan of the lifting brake system,and studies the braking performance of the lifting brake system.The main content of the study is as follows:(1)Analysis and research on configuration strategies.Based on the braking forms of general lifting machinery lifting mechanisms,this paper explores the safety and reliability of lifting braking systems under different configuration methods,mainly considering the form,installation position,combined braking form,regulatory requirements,and other aspects of the brakes,laying a certain foundation for determining the safety braking system of metallurgical electric hoist lifting.(2)Theoretical analysis.Based on the analysis and research of the configuration strategy,the lifting braking system configuration scheme suitable for the metallurgical electric hoist is proposed,the working principle and braking conditions of the system are described,and the safety and reliability of the braking system under different braking conditions are described mathematically using the relevant theoretical knowledge such as kinematics and vibration mechanics.(3)Simulation analysis.Based on practical situations and theoretical analysis,the safety and reliability of the lifting braking system under emergency braking conditions are studied.ABAQUS simulation software is mainly used to simulate the braking process of the brake,and the impact of wear behavior between friction pairs on the braking system is studied.(4)Bench test analysis.Combining theoretical analysis and simulation analysis,build a test bench that can test the braking performance of the electric hoist lifting brake system.Based on the test bench,analyze the braking performance of the lifting braking system under different braking conditions;Analyze the safety and reliability of the lifting braking system,the specific impact of braking factors,and the rationality of the braking system configuration plan through the experimental data obtained;Reveal the impact of the wear mechanism between friction pairs on the braking system through macroscopic,hardness testing,electron microscopy scanning,and other methods.This article conducts a systematic strategy analysis on the safety and reliability of the lifting safety braking system,and systematically studies the braking performance of the lifting braking system through theoretical,simulation,experimental and other methods.This has certain guiding significance for the safe,reliable and reasonable design of the lifting safety braking system of metallurgical lifting machinery.
