Belt conveyor operation monitoring and early warning system

Abstract

The invention discloses a belt conveyor bearing temperature monitoring and early warning system, and belongs to the technical field of equipment state detection. The system comprises a belt conveyor,an early warning unit and multiple monitoring assemblies. According to the monitoring assemblies, the type of a bearing is monitored, the monitoring assemblies are generalized in different early warning area sets, and correspond to one early warning unit, the monitoring assemblies in the same early warning area set send monitored temperature data and vibration data to the corresponding early warning unit through a communication module, comparison is carried out to obtain pairwise comparison difference values of the monitoring assemblies, analysis is carried out according to the high and low sorting, and a regression line is obtained. The early warning unit obtains the belt conveyor bearing stable condition through analysis according to the tendency angle, the highest temperature data valueand the highest vibration data value of the regression line. Through temperature vibration detection, running of a bearing in a belt conveyor is detected, and through the bearing running condition, amonitor can more know the running health condition of the belt conveyor.

Description

technical field [0001] The invention relates to the technical field of equipment state detection, in particular to a belt conveyor operation monitoring and early warning system. Background technique [0002] In the field of cement production, it is necessary to carry ore materials or other materials to the belt conveyor to realize different equipment. As an important protection device of the belt conveyor, the pull switch of the belt conveyor is connected in series. Once the pull switch flashes off, it will cause the belt conveyor to stop frequently. Moreover, since the length of the belt conveyor is measured in kilometers, it is very difficult to find the fault and it is easy to occur. Safety accidents, the consequences are unimaginable, and even cause belt tearing, personal injury and death accidents; as a power transmission device, the belt conveyor gearbox is difficult to overhaul due to harsh working environment, heavy load, and long running time, resulting in gears, dr...

As an important protection device of the belt conveyor, the pull switch of the belt conveyor is connected in series. Once the pull switch flashes off, it will cause the belt conveyor to stop frequently. Moreover, since the length of the belt conveyor is measured in kilometers, it is very difficult to find the fault and it is easy to occur. Safety accidents, the consequences are unimaginable, and even cause belt tearing, personal injury and death accidents; as a power transmission device, the belt conveyor gearbox is difficult to overhaul due to harsh working environment, heavy load, and long running time, resulting in gears, drive shafts and bearings. Various failures occur, such as tooth profile error, gear wear, broken teeth, shaft imbalance, bearing fatigue peeling and pitting, etc. At the same time, the temperature of the gearbox is too high, which reduces the lubrication effect of the components and further aggravates the failure To a certain extent, once a failure occurs, it will cause the equipment to stop and bring huge economic losses to the enterprise; the belt conveyor pulley is an important part of the direct output force in the belt conveyor drive device, and it contacts with the belt to drive the belt conveyor to run through friction. Long running time, excessive load, or uneven coal loading and belt deviation will cause occasional shaft shifting of the drum. Once the shaft of the drum shifts, it will further worsen the deviation of the belt, and even cause serious accidents such as belt tearing. It affects the normal operation of other driving devices of the belt conveyor, causing the paralysis of the entire operation process and causing great losses to production

In the prior art, there is no system or method for comprehensively monitoring the running status of the belt conveyor
