Research on the Structural Design of Coal Mine Hoist Disc Brake
By introducing the current research status of mine hoist disc brake and the characteristics of its control system,the optimal design of its structure is studied.Bidirectional parallel oil circuit and four-cylinder brake are selected for the hydraulic circuit of the brake system.A one-way throttle is set for the disc brake bypass to delay the bypass braking slightly,which will achieve two-stage braking and make the work more stable.This type of disc brake is usually closed,which means that when the hoist is not working,the brake is in the braking state to prevent accidents.This type of brake is safe,reliable and sensitive in action.The brake pad material is made of rigid asbestos plastic,which has a stable friction coefficient,good abrasion resistance,insensitivity to water-containing media and acid and alkali particles,and has a flexible mounting position,making it easy to use,adjust and maintain.
