Detection device and method for scrapping of lifting hook based on image recognition technology

Abstract

The invention provides a detection device for the scrapping of a lifting hook based on an image recognition technology. The detection device comprises a base, two image acquiring devices for simultaneously acquiring an image of the lifting hook, two calibrating plates for calibrating the sizes of the images, two fixed frames which are respectively connected with the side face of the base in an adjusting mode, a lower computer control module, an upper computer control module and a display module, wherein one calibrating plate and one image acquiring device are fixed on each fixed frame; the display module is connected with the upper computer control module. The detection device for the scrapping of the lifting hook, disclosed by the invention, is high in measurement precision and convenient for use and meets the requirement on safe regulation of a hoisting machine; according to the detection device, the opening degree of the lifting hook and the measuring precision of the wear degree of a dangerous section are improved, and the scrapping of the lifting hook can be detected and judged quickly, reliably and accurately. The invention also provides a detection method adopting the detection device. According to the detection method for the scrapping of the lifting hook, the opening degree of the lifting hook and the measuring precision of the wear degree of the dangerous section can be improved, and further the accuracy for detecting and judging the scrapping of the lifting hook is improved.

Description

Technical field [0001] The invention relates to the technical field of engineering detection, and more specifically, to a hook scrap detection device based on image recognition technology and a detection method thereof. Background technique [0002] Lifting machinery is an indispensable logistics and transportation equipment to improve material handling conditions in modern economic construction, and to realize automation and mechanization of the production process and increase labor productivity. Among them, the hook is the most widely used retrieval device on the crane, and one of the important parts of the crane. The hook bears the entire load of the lifting, and its stress condition is very complicated during the working process. In addition to bearing the weight of the heavy object, it also bears the impact load caused by lifting and braking. Therefore, hooks with poor quality or long service life will inevitably have cracks or even breaks during use, which often leaves hid...

AI Technical Summary

Problems solved by technology

However, manual detection will be subjective, and relevant data cannot be measured quickly, reliably and accurately, resulting in large measurement errors of opening degree or wear degree of dangerous sections, low measurement accuracy, low detection efficiency and inaccurate scrap judgment results, etc. question

This test has the problems of high measurement difficulty and low measurement accuracy. Not only can it not reflect the safety information of the hook equipment in time, but it cannot effectively ensure the safe operation of the hoisting machinery.

[0008] Moreover, with the increase in the number of cranes, the inspection business of special equipment has also continued to grow. The traditional inspection method using manual operations and special tools such as vernier calipers and dial indicators for measurement has been unable to meet the accuracy required by the inspection. The labor time spent It is also unable to meet the development needs of today's inspection business
