The invention discloses a brake monitoring method for a mine hoist and a monitoring device thereof. The monitoring method comprises a brake shoe clearance monitoring method for a brake and a deflection monitoring method for a brake disc of the hoist. According to the deflection monitoring method for the elevator brake disc, non-contact displacement sensors are installed on brakes on the two sides of the brake disc, and the non-contact displacement sensors are used for monitoring the linear distance between sensor probes and the surface of the brake disc in real time; the displacement sensors can be arranged on the brake bodies on the two sides of the brake disc to monitor the linear distance between the brake disc and the brake shoe in real time, so that the maximum distance and the minimum distance are detected, the deflection condition of the brake disc is obtained, the problems of uneven stress on the two sides of the brake disc, brake disc heating, brake block smoking and brake base shaking are solved, normal operation of an elevator is met, and the service life of the elevator is prolonged. And in addition, the sensor used for monitoring the brake shoe clearance is arranged, so that the brake shoe can be prevented from generating excessive abrasion during working, and accidents are prevented.

    本发明公开了一种用于矿井提升机的制动监测方法及其监测装置,包括对制动器的闸瓦间隙监测方法以及对提升机闸盘的偏摆监测方法;提升机闸盘的偏摆监测方法包括安装在闸盘两侧制动器上的非接触式位移传感器,非接触式位移传感器用于实时监测传感器探头与闸盘表面之间的直线距离,闸盘偏摆监测时;本发明能够在闸盘两侧的制动器体上设置位移传感器,以实时监测闸盘与闸瓦之间的直线距离,从而检测出最大间距与最小间距,获得闸盘的偏摆情况,以避免闸盘两侧受力不均、闸盘发热、闸块冒烟、闸座晃动的问题,满足提升机的正常运转,提高安全性,此外,设置用于监测闸瓦间隙的传感器,可避免闸瓦在工作时产生过渡磨损,防止造成意外事故。
