Description

Technical Field

[0001] The present invention relates to the technical field of steel structure corrosion detection devices, and in particular to an electromagnetic detection device for steel structure corrosion damage detection and a use method thereof. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Steel structure is easy to rust, and the degree of rust needs to be detected by electromagnetic detection equipment during the use of steel structure.

[0003] The existing electromagnetic detection device for detecting rust damage to steel structures uses an electromagnet to adsorb the steel structure during the detection process, thereby causing the slider to move in the slide groove. However, some iron filings will accumulate in the slide groove, and these iron filings need to be cleaned manually. At the same time, due to the small specifications of the slide groove, it is not convenient for the staff to clean it, which increases the cleaning difficulty of the staff and reduces the practicality of the device. In addition, during use, the existing electromagnetic detection device for detecting rust damage to steel structures is always exposed to the air by the electromagnet, which is easily corroded by moisture in the air, affecting the performance and service life of the electromagnet. In addition, the existing electromagnetic detection device for detecting rust damage to steel structures uses bolts to fix the steel structure, and since the spacing between the slide grooves cannot be adjusted, the device can only be applied to steel structures of the same specification, reducing the functionality of the device. Therefore, an electromagnetic detection device for detecting rust damage to steel structures is urgently needed to solve the existing problems. Summary of the invention

At the same time, due to the small size of the slide slot, it is not convenient for the staff to clean it, which increases the cleaning difficulty of the staff and reduces the practicality of the device. The present invention sets a through cavity, a guide rail, a protrusion and a collection box. During the movement of the slider, the specifications of the through cavity are smaller than those of the slide slot, so that the iron filings spilled in the slide slot can fall into the collection box through the through cavity, and the iron filings are automatically cleaned. The collection box is unloaded by the guide rail and the protrusion to clean the collected iron filings, without manual cleaning, reducing the work intensity of the staff and improving the functionality of the device.

[0025] 2.
