煤矿提升机液压制动装置的研究与分析

Research and Analysis of Hydraulic Brake Device for Coal Mine Hoist

针对传统的换绳工艺速度较慢,会产生新旧绳缠绕的问题,通过分析矿井提升机的换绳技术,对换绳装置和液压制动装置进行具体研究。通过实际换绳装置应用表明,换绳工作从开始到结束仅仅用了5 h,极大地减少了换绳工作的时间;液压制动装置的安装,提升机速度从3.5 m/s降为0,所需时间为6 s,减速度为0.6 m/s^(2),降低了提升机制动成本,保证了提升机运行的稳定性和安全性,为煤矿安全开采提供了必要保障。

For the traditional rope changing process is slow and creates the problem of old and new rope tangling,through practical application,the results show that the rope changing work from the beginning to the end only took 5 h,greatly reducing the time of rope changing work,the installation of hydraulic brake device,hoist speed from 3.5 m/s to 0,the time required is 6 s,the deceleration speed is0.6 m/,reducing the cost of hoist braking,ensuring the stability and safety of hoist operation,and providing the necessary guarantee for safe coal mining.
