[0002] During the construction process, the quality and distribution of steel bars play a decisive role in the stability and durability of the entire building structure. During the construction phase, the steel bars are first laid, and then the pre-prepared concrete slurry is evenly poured into the area where the steel bars are erected, so that a good bond is formed between the steel bars and the concrete, thereby improving the stress-bearing performance of the overall structure. Steel bar depth detection can help determine whether the layout of the steel bars in the building meets the design requirements and evaluate the construction quality of the building structure.

[0003] After searching, the Chinese patent announcement number is: CN220039397U, which discloses a reinforced concrete structure protective layer thickness detection device, which mainly targets the existing reinforced concrete protective layer thickness detection devices, most of which use manually operated ultrasonic detectors to complete the detection of the plate-shaped reinforced concrete protective layer thickness. Due to manual hand-held operation, the detection efficiency is reduced, and the shaking of the arm can easily affect the detection results. In addition, the instrument needs to be frequently changed to complete the detection of the protective layer thickness of different parts of the reinforced concrete, which brings inconvenience to the detection work. The following technical solution is proposed: it includes a support frame and an ultrasonic detector, and the ultrasonic detector is located in the support frame. The utility model realizes rapid positioning of the ultrasonic detector, which is convenient for adjusting its position according to the detection situation, and the device has good flexibility, which solves the problem of inconvenient manual operation. However, in actual use, there are certain limitations in determining the depth of steel bars and internal defects. For this reason, an X-ray steel bar depth detection device is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the present invention provides an X-ray steel bar depth detection device, which aims to improve the problem that the existing technology has certain limitations in determining the depth and internal defects of steel bars.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an X-ray steel bar depth detection device, comprising a mobile platform and a fixed block two, the bottom of the fixed block two is fixedly connected to an X-ray generator, the top of the mobile platform is provided with a lifting assembly, the right side of the X-ray generator is provided with a penetration opening, the top of the fixed block two is provided with a rotating assembly, the top of the mobile platform is provided with a receiver, the left side of the mobile platform is fixedly connected to a data analyzer, the left side of the data analyzer is fixedly connected to a control panel, and the right side of the penetration opening is provided with a tightening mechanism.

[0040] Specifically, the height of the X-ray generator 11 is controlled by the operation of the hydraulic cylinder 6, and the angle of the X-ray generator 11 is controlled by controlling the operation of the servo motor 9, so that the detection device can detect steel bars at different positions and angles, adapt to various complex building structures, and improve the flexibility and comprehensiveness of detection.
