Description
Technical Field
The application relates to a safety monitoring system, in particular to a crane structure safety monitoring system.
Background
The large-scale special equipment plays an important role in each department of national economy, particularly in the field of hoisting machinery, and the number of the hoisting machinery in China is the first in the world and is essential transportation equipment in modern industrial development. At present, 234.79 ten thousand hoisting machines are used in China, 18.9824 ten thousand hoisting machines are used in Guangdong province, the occupation ratio is 1/11, the annual output of the hoisting machine manufacturing industry in the whole province exceeds 6 thousand cranes (sets), and the output value exceeds 150 million yuan. However, the safety problem existing after the development of the hoisting machinery industry is not negligible. Along with the increasing of the output and the market holding quantity of hoisting machinery in China, the accident rate is also increased continuously, and the property loss caused by the increasing is larger and larger. Most of which are caused by structural failure of the hoisting machinery. Therefore, the safety monitoring of the crane structure is particularly important.
The main safety guarantee method for the crane structure in China still mainly comprises regular inspection and monitoring, and most of the adopted technical means are conventional means such as visual inspection, sensory judgment, halt measurement, magnetic particle inspection, ultrasound, rays and the like, but the means still have a plurality of serious defects. On one hand, the conventional detection means is relatively lagged behind, the workload of inspectors is huge, but the detection efficiency is very low, the conventional detection method is basically carried out in a shutdown state, generally only macroscopic defects such as cracks, inclusions, air holes and the like can be detected, before the macroscopic cracks appear, the material defects are accumulated in microscopic damage, although the macroscopic cracks do not exist on the surfaces of some workpieces, the microscopic damage is serious, and if the conventional detection method is continuously used, the normal use of the workpieces is possibly influenced, and even danger occurs. Therefore, it is imperfect to simply detect the macroscopic defects, and the inspection result is difficult to reflect the actual operation state of the hoisting machine. On the other hand, due to the lack of long-period running state quantity, the degradation of the mechanical performance of the crane structure in service cannot be monitored in real time, the residual life of the crane structure cannot be objectively and accurately predicted, and for the crane machinery in service for a long time, accurate data of safety assessment and scientific basis of degradation transformation are lacked.
In recent years, simple stress sensors are adopted at home and abroad successively to acquire danger signals of the hoisting machinery and are compared and analyzed with theoretical calculated values, so that the stress condition and the strength storage condition of the crane can be objectively evaluated, and the problem that the load change of the hoisting machinery structure cannot be monitored in real time is solved to a certain extent. However, such devices also have a number of disadvantages. On one hand, metal defects of the crane, process manufacturing, sudden change of sections caused by inconsistent material thickness, stress concentration areas caused by welding process and the like can generate stress abnormity in stress test, and the existence of the defects can not be judged as the stress abnormity in a whole. On the other hand, the devices have limited functions in preventing sudden accidents, load data are generally collected, and when the load value reaches a threshold value, an alarm is given, so that the accidents already happen, and the purpose and the requirement of 'preventing accidents' cannot be met. Moreover, the absence of expert field detection opinions in the detection system cannot effectively, safely and reasonably supervise the safe operation of the large crane in real time.
Therefore, the current mode of monitoring the safety of the crane structure has the problems of low detection efficiency and poor real-time performance.
