Hook Scrap Detection Device and Its Detection Method Based on Image Recognition Technology

Abstract

The invention provides a hook scrapped detection device based on image recognition technology, which includes: a base; two image collectors for simultaneously collecting images of the hook; two calibration plates for image size calibration; The side of the seat can be adjusted to be connected with a fixed frame, and each fixed frame is fixed with a calibration board and an image acquisition device; a lower computer control module; an upper computer control module; and a display module connected with the upper computer control module. The hook scrapping detection device of the present invention has high measurement accuracy, is easy to use, and meets the requirements of hoisting machinery safety regulations. The detection device can also realize fast and reliable detection while improving the opening degree of the hook and the measurement accuracy of the wear degree of the dangerous section. And accurately detect and judge the scrapping of the hook. The present invention also provides a detection method using the above-mentioned detection device, which can improve the measurement accuracy of the opening degree of the hook and the wear degree of the dangerous section, thereby improving the accuracy of the detection and determination of the scrapped hook.

Description

technical field [0001] The invention relates to the technical field of engineering detection, and more specifically, to a hook scrapped detection device and a detection method based on image recognition technology. Background technique [0002] Hoisting machinery is an indispensable logistics and transportation equipment for improving material handling conditions in modern economic construction, realizing automation and mechanization of production processes, and improving labor productivity. Among them, the hook is the most widely used pick-up device on the crane, and it is one of the important parts of the crane. The hook bears all the loads of hoisting, and its force condition is very complicated during the working process. In addition to bearing the weight of heavy objects, it also needs to bear the impact load generated by lifting and braking. Therefore, the poor quality of the hook or the hook with a long service life will inevitably crack or even break during use, whi...

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
