Description

Technical Field

[0001] The present application relates to the field of magnetization equipment, and in particular to a large-scale component magnetization device and a magnetization method. Background Art

[0002] Gravity pier pier, also known as gravity pier pier or solid pier pier, is a pier structure that relies on its own gravity and external forces to maintain strength and stability. It is mainly composed of several independent piers, which can be block structures, caisson structures or other forms. The piers may be connected by footbridges, etc. The block structure is mainly made of aggregate, water, cement and other admixtures. The total number of large-scale pier blocks exceeds 160, ranging from 337 tons to 510 tons.

[0003] Since the block structure is easily mixed with metal debris such as nails, screws and cables in each link of the actual production process, these debris are easily magnetized in a strong magnetic environment, making the surface of the block structure magnetic, which will interfere with the normal operation of other equipment systems in the terminal, such as the navigation signal in the port's automated transportation system. Therefore, the block structure needs to be inspected. When metal impurities are detected on the surface of the block structure, the metal impurities at the corresponding position need to be chiseled out and the block structure needs to be repaired. Then, in the actual inspection process, general metal detection equipment is difficult to directly detect deeper metal. In order to improve the accuracy of metal detection, the metal can generally be magnetized by magnetization. However, since the current magnetization equipment cannot magnetize components as large and heavy as the block structure, there is still room for improvement. Summary of the invention
