Fault monitoring device for belt sampling head and diagnostic method for fault early warning

Abstract

A belt sampling head failure monitoring device, by connecting the sampling head position detection module, the main shaft detection module, the reducer detection module, the motor detection module and the load detection module to the monitoring management module respectively, the monitoring management module sends the above modules Receive and analyze the data signal and the load data signal of the belt conveyor, monitor the running status of the sampling head in real time, give early warning of the fault information of the sampling head in time, and send the early warning information to the upper-level equipment to ensure the operation reliability of the sampling machine and stability; the diagnostic method of early warning of sampling head failure. Through the recording, analysis and calculation of the data of the belt sampling head during operation, it can be found in time whether the sampling head exceeds the set early warning threshold during the actual conveyor load operation. When any indicator exceeds the early warning threshold, the monitoring and management module will issue early warning information about the failure of the sampling head, and the early warning information will be sent to the upper-level equipment to remind relevant personnel to respond accordingly.

Description

technical field [0001] The invention relates to a belt sampling head failure monitoring device and a diagnosis method for failure early warning, belonging to the technical field of electrical equipment failure monitoring. Background technique [0002] Coal is a bulk commodity with inhomogeneity. Coal commodities are priced by quality. To accurately identify the quality of coal products, it is necessary to sample, prepare and test coal products. Among the three links of sampling, sample preparation and testing in the coal analysis process, sampling is the most important part. Take a part of a batch of materials for testing, and use the obtained test results to represent the quality of the entire batch of materials. This process is called sampling. [0003] Traditional manual sampling is affected by sampling tools, subjective factors, etc., and the test results obtained have large deviations. The error caused by manual sampling accounts for about 80% of the coal quality anal...

AI Technical Summary

Problems solved by technology

The working performance and reliability of the sampling head are directly related to the performance and reliability of the entire sampling device. However, due to the poor working environment of the sampling head, the coal flow is often mixed with some impurities such as plastics, wood chips and even metal chips, which may easily cause sampling problems. Head failure, such as excessive coal flow load and sticky coal, causing the sampling head to get stuck in the coal flow and cause equipment failure; the main shaft of the sampling head is broken during use; the coupling is damaged, causing the sampling head to fail to operate. have a major impact on production and safety
