[0012] Beneficial effects

[0013] In the present utility model, moving brackets are provided on both sides of the detector body. The wire duct and the damping rod on the surface of the detector body both penetrate into the moving bracket and pass through the return spring inside the moving bracket. The damping block is fixed to the moving bracket by being screwed into the threaded hole of the damping rod. A DC motor is provided inside the moving bracket, and the DC motor is electrically connected to the main board inside the detector body. A battery is provided inside the detector body, and a CCD camera is provided on the bottom surface of the detector body.

[0021] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present utility model.

[0022] The specific embodiments of the present utility model will be described below with reference to the drawings. Specific embodiment one:

[0024] Refer to Figures 1-5 , a non-destructive testing device for in-service steel structures, including a detector body 1, moving brackets 2 are provided on both sides of the detector body 1, two damping rods 6 are provided on the surface of the detector body 1, cable ducts 12 are provided on both sides of the two damping rods 6, damping blocks 14 are provided inside the two moving brackets 2, threaded holes 10 are provided on the surfaces of the two damping rods 6, two DC motors 11 are provided inside the two moving brackets 2, pulleys 5 are provided on one side of the two DC motors 11, return springs 9 are provided inside the two moving brackets 2, cover plates 4 are provided on one side of the two return springs 9, fixed bolts 13 are provided on one side of the cover plates 4, a CCD camera 3 is provided on the bottom surface of the detector body 1, a main board 7 is provided inside the detector body 1, a battery 8 is provided on the top of the main board 7, the two damping rods 6 are both provided on both sides of the detector body 1, and the damping rods 6 are provided at the center of the surface of the detector body 1. One end of each of the two damping rods 6 penetrates into the inside of the moving bracket 2, and one end of the damping rod 6 penetrates through the return spring 9. The two damping blocks 14 are threadedly installed in the threaded holes 10 on the surface of the damping rod 6 through the bottom ends, and the damping blocks 14 are threadedly connected to the damping rods 6. The two cover plates 4 are installed on the two moving brackets 2 through the fixed bolts 13, and the cover plates 4 are all provided on the side far from the detector body 1. The cable ducts 12 and the damping rods 6 are in a parallel state, and one end of each of the cable ducts 12 penetrates into the moving bracket 2. One end of each of the four DC motors 11 penetrates through the moving bracket 2, and the pulleys 5 are all installed on the DC motors 11. The DC motors 11 are electrically connected to the main board 7.

[0025] On both sides of the detector body 1, there are moving brackets 2. On the surfaces of both sides of the detector body 1, two wire conduits 12 and damping rods 6 are installed. Both the wire conduits 12 and the damping rods 6 penetrate into the moving brackets 2 and pass through the return springs 9 inside the moving brackets 2. The damping blocks 14 are screwed into the threaded holes 10 of the damping rods 6 to fix the moving brackets 2. The two wire conduits 12 and the damping rods 6 are in a parallel state. The two wire conduits 12 and the damping rods 6 are made of iron material. When the moving brackets 2 move, the two wire conduits 12 will act as guide rods to prevent the moving brackets 2 from rotating during use. Since the diameter of the damping blocks 14 is larger than that of the return springs 9, when the damping blocks 14 are installed, the return springs 9 will be clamped into the inside of the moving brackets 2 by the damping blocks 14. After the damping blocks 14 are installed, the cover plate 4 can be installed on the moving brackets 2 through the fixing bolts 13 to prevent foreign objects from entering the moving brackets 2 and jamming the return springs 9. Inside the moving brackets 2, there is a DC motor 11, and the DC motor 11 is electrically connected to the main board 7 inside the detector body 1. The wires enter the moving brackets 2 through the wire conduits 12 on the surface of the detector body 1 and are connected to the DC motor 11. The DC motor 11 is installed inside the moving brackets 2. Inside the detector body 1, there is a battery 8, and a CCD camera 3 is provided on the bottom surface of the detector body 1. The CCD camera 3 is installed on the bottom surface of the detector body 1 through the fixing bolts 13 and is electrically connected to the main board 7. When in use, pull the moving brackets 2 to open the two moving brackets 2 to both sides, place the detector body 1 on the special-shaped steel frame. The special-shaped steel frame is in the shape of "I", and then release the moving brackets 2 to make the moving brackets 2 stuck on the special-shaped steel frame. At this time, the detector body 1 can be controlled by the remote control. The remote control will transmit the control signal to the main board 7 inside the detector body 1 through the internal transmitter. The main board 7 receives the information and processes it, and transmits the electrical signal of the battery 8 and the processed information to the DC motor 11, so that the DC motor 11 starts and drives the pulley 5 to rotate through the output shaft, so as to make the detector body 1 move. When moving, turn on the CCD camera 3 through the remote control to start the CCD camera 3. The camera of the CCD camera 3 converts the captured object into an image signal, and then sends it to the dedicated image processing system. According to the information such as pixel distribution, brightness, and color, it is converted into a digital signal; the image system performs various operations on these signals to extract the features of the target, and then according to the preset allowable range and other conditions, to achieve the automatic recognition function. When rust or cracks are detected, these images are converted into data, and these data are transmitted to the controller through the main board 7. Specific Embodiment Two:

[0027] Refer to Figures 1-5, three small pulleys 5 can be provided on the surfaces of the two moving brackets 2. The pulleys 5 are arranged in parallel on the surfaces of the moving brackets 2 on the side away from the cover plate 4, and a clamping block is provided on the surface of the moving brackets 2. The pulleys 5 are clamped into the clamping blocks through the rotating shafts at both ends. See (Appendix Figure 5 ). In this way, when the moving bracket 2 contracts, the pulley 5 will abut against the special-shaped steel frame, enabling the detector main body 1 to move normally and preventing the moving bracket 2 from rubbing against the special-shaped steel frame during movement, thereby causing damage to the moving bracket 2.

[0028] To sum up:

[0029] 1. Moving brackets 2 are provided on both sides of the detector main body 1. The wire duct 12 and the damping rod 6 on the surface of the detector main body 1 both penetrate into the moving brackets 2 and pass through the return spring 9 inside the moving brackets 2. The damping block 14 is installed in the threaded hole 10 of the damping rod 6 through threads to fix the moving brackets 2. A DC motor 11 is provided inside the moving brackets 2, and the DC motor 11 is electrically connected to the main board 7 inside the detector main body 1. A battery 8 is provided inside the detector main body 1, and a CCD camera 3 is provided on the bottom surface of the detector main body 1. When in use, pull the moving brackets 2 to open the moving brackets 2 and place the detector main body 1 on the special-shaped steel frame, and then release the moving brackets 2 to make the moving brackets 2 stuck on the special-shaped steel frame. At this time, the detector main body 1 can be controlled by the remote control. When the remote control transmits the signal to the main board 7 inside the detector main body 1 through the internal transmitter, the main board 7 receives the information for processing and transmits the electrical signal of the battery 8 to the DC motor 11 to start the DC motor 11 and rotate the pulley 5, so that the detector main body 1 moves. When moving, turn on the CCD camera 3 through the remote control to start the CCD camera 3 and perform visual detection on the surrounding steel frames. When rust or cracks are detected, convert these images into data and transmit these data to the controller through the main board 7, solving the drawback that manual detection of steel cannot be carried out quickly.
