[0018] The present invention has the following beneficial effects:

[0019] The present invention utilizes the different thicknesses of steel structures to move the detection rod upward or downward, and then the thickness of the steel structure can be judged by the degree of upward or downward movement of the detection rod. Specifically, the motor is started, and the motor drives the rotating shaft to rotate. The rotating shaft drives the rotating sleeve to rotate through the belt, and the rotating sleeve drives the fixed convex ring and the rotating rod to rotate one by one through the sliding sleeve. The rotating rod drives the roller to rotate, and then the device can be driven to move as a whole. During the movement, the thickness of the steel structure can be detected by the lifting of the detection rod. This design does not require manual movement of the device for detection, and while improving efficiency, it can avoid irregular manual operations, which cause inconsistency and subjectivity in the detected data, resulting in inaccurate or unstable measurement results.

[0020] During the detection process of the present invention, if one part is thinner, the detection rod will have space to move downward, and the spring 1 will push the recording pen downward, and then push the air in the fixed sleeve 2 into the air duct, and the air duct will pass the air into the fixed sleeve 1. The air passed into the fixed sleeve 1 will press the detection rod downward, so that the ball at the bottom of the detection rod is always close to the steel structure. In the process of the movement of the trolley, the rotating rod 1 will drive the gear shaft to rotate through the bevel gear, and the gear shaft will drive the rotating rod 2 to rotate through the belt 2. The rotation of the rotating rod 2 will pull the recording paper wrapped thereon, and will also cause the paper roll to rotate to continuously output the recording. Recording paper. When the recording paper moves, the recording pen will leave marks on it. When the recording pen moves up and down, the marks left on the recording paper will also change synchronously. By making the lines drawn by each recording pen have different colors, it is possible to determine which position the record pen is drawing. When the line rises or falls, it means that some parts of the steel structure are thicker or thinner. This design can record the thickness of each part of the steel structure when detecting it, and can intuitively display the changing trend of the detected thickness, making the data easier to understand and analyze, providing a reference basis for subsequent maintenance, and thus improving the efficiency and accuracy of detection.

[0021] In the process of the recording pen moving up and down, the present invention will drive the detection light ring 1 downward or drive the detection light ring 2 upward. The downward movement of the detection light ring 1 will drive the pressure ring 1 to compress the air in the fixed sleeve 3, and then pass the air in the fixed sleeve 3 into the hose 1. The hose 1 will pass the air into the fixed sleeve 4, and use the air to squeeze the marking pen downward and stretch the spring 2. The marking pen moves downward and contacts the steel structure and leaves a mark on it. Similarly, the upward movement of the detection light ring 2 will compress the air in the fixed sleeve 5 through the pressure ring 2, and input the air into another fixed sleeve 4 through the hose 2 and the hose 3. The steel structure is then marked by pressing the marking pen downward. The specific position can be observed in conjunction with the recording paper. The fixed sleeve 4 is fixedly connected to the outer surface of the detection rod, so that the marking pen can always maintain a fixed distance from the steel structure. This distance is the maximum allowable error. This design can use the marking pen to mark the vicinity of the thickness defect position, and can accurately determine the defective position by comparing it with the information recorded on the recording paper, which can reduce the time and labor cost of manual marking while improving the efficiency of detection.

[0022] When the device of the present invention moves to the final position or there is an obstacle in front of the device, as the device moves, the detection plate will contact the obstacle. As the device continues to move, the detection plate will compress spring three and then retract into the fixed rod, and by pushing the air in the fixed rod, the sliding plate will compress spring four and extend out from the fixed rod. When the sliding plate moves, it will drive the sliding sleeve teeth to move together, thereby disengaging the sliding sleeve teeth from the rotating sleeve teeth. At this time, the rotating sleeve teeth are in an idling state and can no longer drive the device to move, thereby stopping the device. This design can automatically detect obstacles and stop, which can effectively prevent the device from being damaged, reduce the need for human intervention, and further improve the automation and detection efficiency of the device.

The rotation of the second 201 will pull the recording paper 205 wound thereon, and will also cause the paper roll 206 to rotate to continuously output the recording paper 205. During the movement of the recording paper 205, the recording pen 211 will leave a mark on it. When the recording pen 211 moves up and down, the mark left on the recording paper 205 will also change synchronously. By making the color of the line drawn by each recording pen 211 different, it is possible to determine which position the mark of the recording pen 211 is. When the line rises or falls, it means that the steel structure 113 has a thicker or thinner part. This design can record the thickness of each part of the steel structure 113 when detecting it, and can intuitively display the changing trend of the detected thickness, making the data easier to understand and analyze, and providing information for subsequent The invention provides a reference basis for maintenance, thereby improving the efficiency and accuracy of detection. In the process of the recording pen 211 moving up and down, it will drive the detection light ring 1 301 downward or drive the detection light ring 2 308 upward. The detection light ring 1 301 moving downward will drive the pressure ring 1 302 to compress the air in the fixed sleeve 303, and then pass the air in the fixed sleeve 303 into the hose 1 304. The hose 1 304 will pass the air into the fixed sleeve 4 305, and use the air to squeeze the marking pen 306 downward and stretch the spring 2 307. The marking pen 306 moves downward and contacts the steel structure 113, leaving a mark on it. Similarly, the detection light ring 2 308 moves upward and compresses the air in the fixed sleeve 5 310 through the pressure ring 2 309.And the air is input into another fixed sleeve four 305 through the hose two 311 and the hose three 312, and then the steel structure 113 is marked by pressing down the marking pen 306. The specific position can be observed in conjunction with the recording paper 205. The fixed sleeve four 305 is fixedly connected to the outer surface of the detection rod 111, so that the marking pen 306 can always maintain a fixed distance from the steel structure 113. This distance is the maximum allowable error. This design can use the marking pen 306 to mark the vicinity of the thickness defect position, and can compare with the information recorded on the recording paper 205 to accurately determine the defective position, which can reduce the time and labor cost of manual marking while improving the efficiency of detection. When the device moves to the final position or there is an obstacle in front of the device When the device encounters an obstacle, the detection plate 401 comes into contact with the obstacle as the device moves. As the device continues to move, the detection plate 401 compresses the spring three 402, which then retracts into the fixed rod 403. By pushing the air in the fixed rod 403, the sliding plate 404 compresses the spring four 405 and extends from the fixed rod 403. As the sliding plate 404 moves, it also drives the sliding sleeve gear 406 to move, thereby disengaging the sliding sleeve gear 406 from the rotating sleeve gear 408. At this time, the rotating sleeve gear 408 is in an idling state and can no longer drive the device to move, thereby stopping the device. This design can automatically detect obstacles and stop the device, effectively preventing damage to the device, reducing the need for human intervention, and further improving the automation and detection efficiency of the device.
