Assembly type steel structure weld joint detection device

Abstract

One or more embodiments of the invention provide an assembly type steel structure weld joint detection device. The device comprises a detection chamber. A conveying belt penetrates through the hollowinterior of the detection cavity. Through the conveyor belt, the steel structure can be conveyed through the hollow interior of the detection cavity. Through the magnetic powder spray head close to the feeding hole, magnetic powder can be uniformly sprayed on the steel structure. A magnetic field is generated through an electromagnetic device at the bottom end in the detection cavity, and the steel structure in the detection cavity can be magnetized. A leakage magnetic field is generated at a weld joint or a crack defect on the surface of the steel structure, to absorb and collect magnetic powders. The image information of the steel structure can be shot through the image shooting device close to the discharging opening, the image information is transmitted to the image processor, the grayvariance of the image information is processed and analyzed through the image processor so that the gathered magnetic powder can be detected, automatic batch detection can be achieved, detection is visual and convenient, and the detection efficiency is high.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of fabricated steel structure detection, and in particular to a weld seam detection device of fabricated steel structure. Background technique [0002] The prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories are processed and manufactured, transported to the construction site, and assembled and installed on site through reliable connection methods. , among them, the prefabricated steel structure is widely used in various buildings because of its unique performance. The construction steel structure usually needs to be welded when it is used, and the welds and cracks that may be caused by welding are obviously harmful to the use of steel structures. The safety performance is very important, so it is necessary to detect the weld seam, and the tradi...

[0002] The prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories are processed and manufactured, transported to the construction site, and assembled and installed on site through reliable connection methods. , among them, the prefabricated steel structure is widely used in various buildings because of its unique performance. The construction steel structure usually needs to be welded when it is used, and the welds and cracks that may be caused by welding are obviously harmful to the use of steel structures. The safety performance is very important, so it is necessary to detect the weld seam, and the traditional weld seam inspection device often needs to be manually hand-held to complete the inspection, which is time-consuming and laborious, and the detection efficiency is low. The detection efficiency and labor intensity cannot meet the needs of mass welding. Due to the various styles of welds in steel structures, the traditional weld detection device needs to reach and align with the welding position and observe the data in real time, resulting in inconvenient operation and poor practicability
