A smart diagnosis method for steel crane beams based on real-time monitoring

Abstract

The present invention relates to a real-time monitoring-based intelligent diagnosis method for steel crane girders, which includes the following steps: (1) initial detection: obtaining detection parameters and ratings, the detection parameters include ① fatigue cracks, ② track eccentricity, ③ appearance quality and safety, ④ Usability of appearance quality; (2) Real-time wireless monitoring: Obtain and rate monitoring parameters, including ⑤ strain value and ⑥ deflection value; (3) Intelligent diagnosis: conduct safety inspection according to the rating results of parameters ①, ②, ③, and According to the rating results of parameters ④ and ⑥, the usability rating is performed, and on this basis, the reliability of the steel crane girder is rated in real time. The present invention is based on a real-time wireless monitoring method, which can evaluate the safety, usability and reliability of the steel crane girder in real time after the initial detection of the equipment and under long-term unsupervised conditions, and grasp the status of the steel crane girder at any time, saving time and cost , and provide a basis for subsequent analysis of component damage causes and deterioration trends.

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
