摘　　要：针对当前控制技术在矿井提升机减速转换装置中电压与油压变化的响应速度较慢导致减速度响应过慢、提升机启动时易出现冲击造成设备故障的问题,提出一种矿井提升机减速转换装置电液控制方法。将电磁比例溢流阀作为关键电液元件,并测定伺服阀流量。根据减速度计算原理及闭环控制增益原理,构建减速转换装置控制模型。增加盘形制动器,构建盘形制动器数学模型,完成减速转换装置电液控制。应用测试结果表明,该技术对电压与油压变化的响应速度较快,可在短时间内完成减速度响应,避免出现设备启动冲击现象。Aiming at the problem that the current control technology responds slowly to the change of voltage and oil pressure in the deceleration conversion device of mine hoist,which leads to the slow deceleration response,and the impact when the hoist starts,which causes equipment failure,an electrohydraulic control method for the deceleration conversion device of mine hoist was proposed.Took the electromagnetic proportional relief valve as the key electro-hydraulic component,and measured the flow of the servo valve.According to the deceleration calculation principle and the closed-loop control gain principle,the control model of the deceleration conversion device was constructed.Added disc brake,built the mathematical model of disc brake,and completed the electrohydraulic control of deceleration conversion device.The application test results show that this technology has a fast response to the change of voltage and oil pressure,and can complete the deceleration response in a short time to avoid equipment startup impact.
