Title
(EN) Hoist spindle crack online monitoring system and working method thereof
(ZH) 提升机主轴裂纹在线监测系统及其工作方法
Abstract
(EN)
The invention discloses a hoist spindle crack online monitoring system and a working method thereof. The system comprises a rope power portion, a crack detecting portion, a wireless transmission portion, and a computer. The rope power portion comprises two traction ropes, two guide wheels, two stepping motors and two stepper motor drivers. The crack detecting portion comprises a spiral guide rail,a sliding body, and an ultrasonic generator. The wireless transmission portion comprises three zigbee wireless sensing modules. The zigbee wireless sensing module accepts commands from the computer and passes the commands to the stepper motor driver to control the rotation of the motor. The stepping motor drives the guide wheel to rotate to realize the winding of the rope to pull the sliding bodyto slide on the spiral guide rail. The ultrasonic generator clamped on the sliding body monitors the rotating spindle along the spiral guide rail. The zigbee wireless sensing module transmits the detected data to the computer in real time. The invention can monitor in time before the hoist spindle fails, thereby avoiding accidents.
