Steel crane beam intelligent diagnosis method based on real-time monitoring

Abstract

The invention relates to a steel crane beam intelligent diagnosis method based on real-time monitoring, and the method comprises the following steps: (1) initial detection: obtaining and grading detection parameters which comprise (1) fatigue crack, (2) track eccentric distance, (3) appearance quality safety, and (4) appearance quality usability; (2) real-time wireless monitoring: acquiring monitoring parameters and rating, wherein the monitoring parameters comprise a strain value (5) and a deflection value (6); and (3) intelligent diagnosis: performing safety rating according to rating results of the parameters 1, 2, 3 and 5, performing usability rating according to rating results of the parameters 4 and 6, and performing real-time rating on the reliability of the steel crane beam on thebasis. On the basis of a real-time wireless monitoring means, the safety, usability and reliability of the steel crane beam can be rated in real time, the condition of the steel crane beam can be mastered at any time, time and cost are saved, and a basis is provided for subsequent analysis of component damage reasons and degradation trends after initial detection of equipment is completed and under the condition of long-term unsupervised operation.

Description

technical field [0001] The invention relates to structural intelligent diagnosis technology, in particular to an intelligent diagnosis method for steel crane beams based on real-time monitoring, belonging to the field of structural intelligent diagnosis of buildings. Background technique [0002] The steel crane beam is a very important structural component of the industrial plant. Whether the steel crane beam can work normally directly affects the production operation, especially the steel crane beam of the heavy-duty and extra-heavy working cranes in the steel-making plant. Usually, the tonnage Large and run frequently. In recent years, with the vigorous development of the steelmaking industry, steelmaking plants have continued to increase production and expand capacity, which has further aggravated the workload of steel crane beams, and damage and cracking of steel crane beams have occurred from time to time. [0003] At present, the diagnosis technology for steel crane ...

AI Technical Summary

Problems solved by technology

Due to the busy production and complex environment in industrial plants, there are many inconveniences in the investigation and testing of steel crane girders; and the on-site measurement work is usually only carried out once, and the status of steel crane girders cannot be obtained in real time. An intelligent diagnostic method is urgently needed to solve the above problems
