Abstract

The invention discloses a metal surface fatigue detecting system and a metal surface fatigue detecting method for an off-shored crane. The detecting system comprises a plurality of strain sensors and a detecting computer, wherein the plurality of strain sensors are arranged at a plurality of preset positions of the off-shored crane to detect stress data of each preset position of the off-shored crane under different working conditions; the detecting computer comprises a computing device and a display device; the display device is connected to the plurality of the strain sensors to receive the stress data for generating a variation image of the stress data and judging fatigue degree according to a preset model; and the display device is connected to the computing device for displaying the variation image and the judged results of the fatigue degree. According to the scheme, the off-shored crane realizes real-time detection display of the stress data, and guarantees fatigue degree detection and fault early warning in an operation process of the off-shored crane.

Description

technical field [0001] The invention relates to the field of lifting equipment, in particular to a fatigue detection system and method for a metal structure of a shore bridge crane. Background technique [0002] Due to the harsh environment, complex working conditions, and high level of work, fatigue has become the most important form of damage for shore-to-shore bridge cranes. The current inspection technology mostly focuses on visual inspection methods, and there is no better method for fatigue strength inspection. [0003] "Code for Design of Cranes" (GB / T3811-2008) clearly stipulates the structural fatigue strength check: use the stress ratio method to analyze and calculate the design load stress range, obtain the stress cycle characteristic value, and then according to the stress concentration level of the component Obtain the basic value of the fatigue allowable stress, and combine the calculation formula to obtain the fatigue allowable stress value of the component. ...
