Abstract

The invention discloses an escalator main driving wheel state monitoring system. The system comprises a clamping-type electromagnetic monitoring device, an angle positioning device and a data collecting and processing module, wherein the clamping-type electromagnetic monitoring device comprises a clamping support and three electromagnetic modules; each electromagnetic module comprises an E-shapedmagnetic core, an exciting coil and two induction coils, magnetic force lines emitted by the exciting coils pass through a main driving wheel and then penetrate through the induction coils at the twosides to form a closed circuit, and a detection area is formed; the data collecting and processing module is connected with the induction coils of all the electromagnetic modules so as to detect the defects of the main driving wheel according to magnetic flux; and the angle positioning device is mounted on a rotating shaft of the main driving wheel so as to position the main driving wheel throughthe rotation of the main driving wheel. According to the system, the magnetic flux change of the main driving wheel is detected through the three electromagnetic modules, the defects are judged and positioned, reliable data support is provided for timely maintenance of an escalator, and the operation safety of the escalator is guaranteed.

本发明公开了一种自动扶梯主驱动轮状态监测系统，包括夹持式电磁监测装置、角度定位装置和数据采集处理模块，夹持式电磁监测装置包括夹持支架和三个电磁模块；电磁模块包括E型磁芯、激励线圈和两个感应线圈，激励线圈发射的磁力线经过主驱动轮，再穿过两侧的感应线圈形成闭合回路，形成一个检测区域；数据采集处理模块与各电磁模块的感应线圈分别连接，以通过磁通量情况，对主驱动轮的缺陷进行检测；角度定位装置安装在所述主驱动轮的旋转轴上，以通过所述主驱动轮的转动实现对所述主驱动轮的定位。本发明通过三组电磁模块检测主驱动轮的磁通量变化，判断和定位缺陷，为自动扶梯的及时检修提供可靠的数据支持，保障自动扶梯的运行安全。
