The invention provides an abnormality detection system of a passenger conveyor, which can check whether a wheel is abnormal or not during operation and dispose the wheel before the wheel is in a state requiring emergency stop. According to one embodiment of the invention, the abnormality detection system of the passenger conveyor is provided with a plurality of steps, and wheels supporting the steps move along a guide rail arranged in a truss. The abnormality detection system of the passenger conveyor is provided with a sensor, an inspection mechanism and a control device. The sensor detects the passage of each step at a specified inspection part on the guide rail. The inspection mechanism pushes the side surface of the wheel of each step at the inspection part along the axial direction with a certain force so as to inspect the inclination state of the wheel. And the control device judges whether the wheels of each step are abnormal or not according to the detection time of the sensor and the inspection result of the inspection mechanism.
本发明提供一种乘客输送机的异常检测系统,能在运转中查验车轮有无异常、在变为需要紧急停止的状态之前加以处置。本发明的一实施方式的乘客输送机的异常检测系统是具有多个梯级、支承这些梯级的车轮沿配设在桁架内部的导轨行进的乘客输送机的异常检测系统,其具备传感器、检查机构以及控制装置。上述传感器在上述导轨上规定的检查部位探测上述各梯级的通过。上述检查机构在上述检查部位沿轴向以一定的力推压上述各梯级的车轮的侧面来检查上述车轮的倾斜状态。上述控制装置根据上述传感器的探测时刻和上述检查机构的检查结果来判断上述各梯级的车轮有无异常。
