The invention discloses a monitoring system for a disc brake of an elevator, and relates to the field of elevators. A magnetostriction sensor is installed on a shoe to measure a brake gap, a photoelectric encoder is installed at the shaft end of a roller to monitor the rotating state of the roller, a strain gauge is installed on a shoe push rod to measure the brake positive pressure, a detection unit and a PLC are used cooperatively to achieve self-adaptive feedback adjustment, a servo motor cooperates with a ball screw pair to push the brake shoe, rapid response, on-line brake torque adjustment and self-adaptive brake spacing adjustment can be achieved, vibration sensors are installed in the horizontal direction and the vertical direction of the shoe respectively and are used for detecting the vibration states in the horizontal direction and the vertical direction respectively, the vibration condition of the brake in the working process can be accurately measured, safe operation of abrake system is guaranteed, potential safety hazards are repaired and alarmed timely, the failure rate of the brake is substantially reduced, and reliable braking and stable operation of a mine hoistare guaranteed.

    本发明公开了一种提升机盘式制动闸的监控系统,涉及提升机领域。磁致伸缩传感器安装在闸瓦上测量制动间隙,光电编码器安装在滚筒轴端,监控滚筒转动状态,应变片安装在闸瓦推杆,测量制动正压力,检测单元与PLC的配合使用实现自适应反馈调节,使用伺服电机配合滚珠丝杆副推动制动闸瓦,能够实现快速反应、在线调整制动力矩、自适应调节制动间距,在闸瓦水平方向和竖直方向各安装一个振动传感器,分别用于检测水平与竖直方向的振动状态,能够精确测量制动闸在工作过程中的振动情况,保证制动系统的安全运行,对存在的安全隐患及时修复与报警,大幅度降低制动器的故障率,保障了矿井提升机的可靠制动和稳定运行。
