Condition Monitoring of Brake Discs and Optimisation of Braking System for Mining Hoists
Aiming at the problems of slow braking speed,large braking impact and lack of stability that exist in the non-closed-loop control mode of the hoist system,a new brake disc state monitoring and braking system for the hoist is proposed.The brake disc status monitoring module realizes real-time monitoring of the brake disc status,provides basic data information for the braking system and realizes closed-loop regulation,which solves the shortcomings of the traditional control mode that can only brake poorly according to the preset procedures.The whole system structure,brake disc monitoring scheme and practical application were studied.The results show that the new braking system can reduce the braking reaction speed of the hoist by 33.3％,reduce the braking impact by 72.4％,and greatly improve the operational stability and reliability of the hoist.
