A steel strip deviation monitoring and automatic alarm system

Abstract

The utility model discloses a kind of steel band deviation monitoring and automatic alarm system, including deviation monitoring device and alarm device;Deviation monitoring device is set respectively on the both sides of conveying steel band, and it include: limit wheel and proximity switch;Limit wheel is set in the side of conveying steel band, with certain distance interval, limit wheel is passively rotated and is set, its wheel surface corresponds the side of conveying steel band, when conveying steel band deviates and contacts limit wheel wheel surface, then drives limit wheel to rotate;Proximity switch is set on one side of limit wheel wheel surface;The wheel surface of limit wheel corresponds the position of proximity switch and is opened groove, multiple are set in the circumferential direction of wheel surface in groove, form periodic signal trigger surface, when limit wheel rotates, proximity switch periodically detects wheel surface and groove, its frequency is positively correlated with conveying steel band operating speed, and deviation is triggered by threshold value determination.This utility model can realize unmanned intelligent monitoring, reduce the uncertainty of manual inspection, greatly reduce deviation fault discovery time.
