Description

Technical Field

[0001] The utility model relates to the technical field of steel structure detection, in particular to a detection mechanism for steel structures. Background Technique

[0002] Steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. In a steel structure, the components or parts are connected by welds, bolts or rivets. Steel structures have the characteristics of high strength, light self-weight, strong deformation ability, good toughness and high reliability. Applying steel structures in construction projects can effectively improve the performance of construction projects and save construction costs. In order to ensure the quality of steel structures without damage, it is necessary to conduct non-destructive testing on steel structures. In the existing public patents: a steel structure detection device (publication number: CN220438034U), "By starting the motor to drive the movable rod and the first gear to rotate, the second gear meshing with the first gear will be driven to rotate, and the first threaded rods at both ends will rotate. Due to the existence of threads, the support plate can be driven to slide and adjust inside the rectangular opening, so as to drive the first clamping plates at both ends to clamp and fix the steel structure placed on the top of the detection table, which can be applicable to steel structures of different lengths. Then rotate the turntable to drive the second threaded rod to rotate, and the second clamping plates at both ends can be driven to move inward, so as to fix the placed steel structure again, which can be applicable to steel structures of different widths, and the fixing effect is good. By starting the hydraulic cylinder to work, the pressure plate can be driven to press down until the pressure sensor contacts the steel structure, which is convenient for stress detection of the steel structure." There are still certain defects in the process of use. During the existence and use of steel structures, a lot of dust will adhere to the surface and a lot of rust will be generated. In the above patent, the surface of the steel structure cannot be cleaned, and too much dust and rust will affect the detection results, and then reduce the detection accuracy.

[0026] Specifically, the moving block 5 slides in the fixed slot 2 to restrict the moving block 5, and the moving plate 6 is slidably connected to the surface of the workbench 1, enabling the moving plate 6 to move stably.

[0027] Preferably, the upper end of the first hydraulic rod 7 is fixedly connected to the lower part of the sliding plate 8, and the outer side of the limit slider 11 is slidably connected to the outer wall of the moving plate 6.

[0028] Specifically, the sliding of the limit slider 11 and the moving plate 6 makes the entire dust extraction frame 12 move stably.
