新型高性能提升机智能电液制动系统的研究

摘要

The high performance intelligent electro-hydraulic hoist braking system further improves the safety of large mine hoist braking performance.Using modern electro-hydraulic control theory,the system is made up of high performance disc brakes,brake on-line monitor system,constant deceleration,hydraulic station,constant deceleration cabinet and the speed measurement equipment.When emergency braking,the system can always brake as the pre-set deceleration speed,not change along with load or working conditionIt not only improves the safety and reliability of mine hoist,but also improves production efficiency.%为进一步提高大型矿井提升机安全制动性能,运用现代电液控制理论,设计了由高性能盘形制动器、制动器在线监控系统、恒减速度液压站、恒减速度电控柜,以及测速装置组成的智能电液制动系统。该系统在紧急制动时,能使制动减速不随负载、工况变化而变化,始终按预先设定的减速度值进行制动,既可提高矿井提升机的安全可靠性,又提高生产效率。
