Research on Multi-Channel Constant Deceleration Braking System for a Hoist
In order to solve the problems of high impact force and unstable braking of mine hoists with constant torque braking,this paper proposes a constant deceleration hydraulic station based on previous research to improve braking performance.At the same time,in order to effectively strengthen the stability of the braking process and reduce hydraulic circuit oil pressure impact,a multi-channel constant deceleration hydraulic braking system is designed.By connecting double proportional relief valves in the circuit for pressure regulation,the redundant design of the constant deceleration braking system is achieved,providing a basis for the smooth and safe operation of the hoist.
