The crack detector is no longer located in the crawler lamp tube 50. The staff takes the crawler lamp tube 50 placed on the load-carrying rotation unit.

[0048] Working principle: During operation, the staff places the crawler lamp tube 50 to be inspected on the load-carrying rotation unit, and drives the lifting box 2 to move downward through the damping lifting structure. When the force of the bottom of the pressing ring 3 pressing the top of the crawler lamp tube 50 reaches a preset value, the damping lifting structure stops driving the lifting box 2 to move downward, and drives a plurality of first threaded sleeves 4 and the pressing ring 3 to rotate through the synchronous driving assembly. The first threaded sleeve 4 drives the first screw rod 5 and the crack detector to move downward relative to the lifting box 2. The crack detector detects cracks on the inner wall of the crawler lamp tube 50, and the pressing ring 3 drives the crawler lamp tube 50 to rotate relative to the operating table 1 through friction, so that the crack detector detects different positions on the inner wall of the crawler lamp tube 50. When the crack detector detects cracks, the first threaded sleeve 4 drives the first screw rod 5 and the crack detector to move downward relative to the operating table 1. After the test is completed, the lifting box 2 is driven to move up to the initial height through the damping lifting structure, the pressing ring 3 no longer presses the crawler lamp tube 50, and the first threaded sleeves 4 and the pressing ring 3 are driven to rotate in the opposite direction through the synchronous driving component, so that the first screw rod 5 and the crack detector are reset to the initial height relative to the pressing ring 3, and the crack detector is no longer located in the crawler lamp tube 50. The staff can take the crawler lamp tube 50 placed on the object-carrying rotation unit, and the force of the pressing ring 3 and the object-carrying rotation unit to clamp the crawler lamp tube 50 can be within a preset range, so as to avoid cracks in the crawler lamp tube 50 after being clamped and fixed, reduce the defective rate, and facilitate the simultaneous detection of the inner walls of multiple crawler lamp tubes 50, thereby improving the detection efficiency;

[0049] The first damping disk 12 is driven to rotate by the servo motor 11, and the first damping disk 12 drives the second damping disk 13 and the second screw rod 14 to rotate by friction. The second screw rod 14 drives the second threaded sleeve 15 and the lifting box 2 to move downward, and the second guide column 48 slides relative to the guide sleeve 49. The second guide column 48 and the guide sleeve 49 are designed to enable the lifting box 2 to move smoothly in the vertical direction. When the force of the bottom of the pressing ring 3 pressing the crawler lamp tube 50 reaches a preset value, as the first damping disk 12 continues to rotate, the first damping disk 12 cannot drive the second damping disk 13 to rotate continuously by friction. The camera 7 on the mounting seat 6 can be used to detect cracks on the inner wall of the crawler lamp tube 50. The bright lamp 8 illuminates the interior of the reptile lamp tube 50. When the lifting box 2 needs to be driven to move upward, the servo motor 11 drives the first damping disk 12 to rotate in the opposite direction. The first damping disk 12 drives the second damping disk 13 to rotate in the opposite direction through friction, so that the second screw rod 14 drives the second threaded sleeve 15 and the lifting box 2 to move upward. When the lifting box 2 moves up to the initial height, the top of the lifting box 2 contacts the bottom of the support ring 43, and the support ring 43 limits the position of the lifting box 2, and the lifting box 2 stops moving up. With the continuous rotation of the first damping disk 12, the first damping disk 12 cannot drive the second damping disk 13 to rotate continuously through friction, so that the lifting box 2 automatically stops after moving up to the preset position.

[0050] When the lifting box 2 moves downward so that the pressing ring 3 contacts the top of the crawler lamp tube 50, as the lifting box 2 continues to move downward, the distance between the lifting box 2 and the pressing ring 3 decreases, the compression spring 19 is in a compressed state, and the pressure applied by the compression spring 19 to the lifting seat 16, the first threaded sleeve 4 and the pressing ring 3 increases, and the pressure on the crawler lamp tube 50 increases. At this time, the side of the stop plate 36 away from the movable plate 34 contacts the side wall of the support block 18, and the tension spring 35 is in a tensioned state. As the lifting box 2 and the stop plate 36 continue to move downward, the stop plate 36 slides vertically relative to the support block 18, and the lifting box 2 drives the first rotating sleeve 22 and the second damping ring 21 to move downward synchronously, and the distance between the second damping ring 21 and the first damping ring 20 decreases. , and the lifting box 2 drives the fixed box 26 to slide relative to the first rotating shaft 24 through the connecting shaft 28, and the second rotating sleeve 23 drives the guide bar 27 to slide in the guide groove 25. When the force of the pressing ring 3 pressing the crawler lamp tube 50 reaches a preset value, the bottom horizontal position of the support block 18 is consistent with the top horizontal position of the stop plate 36, and the tension spring 35 drives the movable plate 34 and the stop plate 36 to move, so that the top of the stop plate 36 is in contact with the bottom of the support block 18, and at this time the second damping ring 21 is in contact with the first damping ring 20. When the servo motor 11 drives the first damping disk 12 to rotate continuously, the first damping disk 12 cannot drive the second damping disk 13 to rotate synchronously through friction, and at this time the first damping disk 12 drives the first rotating shaft 24 to rotate, and the first rotating shaft 24 drives the second rotating sleeve 23, the first connecting column 33 and the gear ring 32 to rotate through the guide bar 27, the gear ring 32 drives the connecting shaft 28 and the second gear 30 to rotate through the third gear 31, the second gear 30 can drive the first rotating sleeve 22 and the second damping ring 21 to rotate through the first gear 29, the second damping ring 21 drives the first damping ring 20, the first threaded sleeve 4 and the pressing ring 3 to rotate through the friction force, the pressing ring 3 can drive the crawler lamp tube 50 to rotate relative to the operating table 1 through the friction force, and at this time the first threaded sleeve 4 drives the first screw rod 5 to slide downward relative to the lifting box 2, the first screw rod 5 and the slide groove 47 slide relative to the prism 46, so that the camera 7 can move downward, when the mounting seat 6 and the camera 7 are lowered to the lowest position, the bottom end of the stop column 9 and the load When the lifting box 2 is lifted up, the first rotating shaft 24 is in contact with the first damping ring 20, and the first threaded sleeve 4 is in contact with the first damping ring 20. ..., the first threaded sleeve 4 is in contact with the first damping ring 20, and the first damping ring 20 is in contact with the first damping ring 20. When the lifting box 2 is lifted up, the first rotating shaft 24 is in contact with the first damping ring 20, and the first threaded sleeve 4 is in contact with the first damping ring 20. When the lifting box 2 is lifted up, the first rotating shaft 24 is in contact with the first damping ring 20, and the first threaded sleeve 4 is in contact with the first damping ring 20, the first threaded sleeve 4 is in contact with the first damping ring 20, and the first threaded sleeve 4 is in contact with the first damping ring 20. When the lifting box 2 is lifted up, the first rotating shaft 24 is in contactWhen the lifting box 2 moves up to the initial height and the first screw rod 5 drives the crack detector to be pulled out of the crawler lamp tube 50, the staff can remove the crawler lamp tube 50 from the load-carrying rotation unit, and the staff holds the handle 37 and drives the handle 37 and the stop plate 36 to move so that the top of the stop plate 36 is no longer in contact with the bottom of the support block 18, and the tension spring 35 is in a tensioned state, releasing the support positioning of the support block 18, and the compression spring 19 drives the lifting seat 16 and the first guide column 17 to move downward, so that the first threaded sleeve 4 drives the first damping ring 20 to move downward relative to the second damping ring 21, and the tension spring 35 applies tension to the movable plate 34 to make the stop plate 36 close to the side wall of the support block 18, and finally the pressing ring 3 drops to the initial position relative to the lifting box 2;

[0051] The staff inserts the bottom end of the crawler lamp tube 50 into the corresponding loading slot 39 and limits the position of the crawler lamp tube 50 by the loading slot 39. When the pressing ring 3 presses the crawler lamp tube 50 and the pressing ring 3 drives the crawler lamp tube 50 to rotate, the loading block 38 drives the second rotating shaft 42 to rotate relative to the operating table 1 through the clamping block 41, so that the crawler lamp tube 50 rotates relative to the operating table 1. When the crawler lamp tube 50 needs to be disassembled, the staff drives the crawler lamp tube 50 to move upward to make the bottom end of the crawler lamp tube 50 disengage from the corresponding loading slot 39. When it is necessary to inspect crawler lamp tubes 50 of different specifications, the staff drives the loading block 38 to move upward to make the clamping block 41 disengage from the clamping slot 40 to complete the removal of the loading block 38. According to the specifications of the crawler lamp tube 50, the loading block 38 with loading slots 39 of other specifications can be replaced.
