Design and Test of Intelligent Safety Protection System for Vertical Shaft Friction Hoisting
Aiming at the phenomenon of friction hoist skidding and rope slipping in a mine,we use dynamics to analyse the friction hoisting system,and design a friction hoisting system skidding and rope slipping accident intelligent protection system according to the principle of mechanics,and make the friction hoisting system skidding and rope slipping accident intelligent protection equipment,and select the type of electronic control components.Through the experiments on the protection system,the results show that:whether it is forward or reverse,the difference between the actual displacement of the guiding wheel and the friction wheel when the rope is slipping is less than 2m,and the reaction time of the rope-slip and skidding accident phenomena is less than 2s,which shows that the system perceives the rope-slip signals accurately,and the response is sensitive and reliable.
