[0012] Figure 2 for Figure 1 A partial enlargement of the marked area. DETAILED DESCRIPTION

[0013] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0014] See also Figure 1-Figure 2 The utility model provides a pipe inspection device, including a pipe conveying mechanism 1, a visual inspection module 2 and a rotating mechanism. The rotating mechanism is arranged at the output end of the pipe conveying mechanism 1, and the visual inspection module 2 is arranged on one side of the rotating mechanism. The pipe conveying mechanism 1 conveys the pipe axially to the rotating mechanism and places the pipe in the inspection position of the visual inspection module 2.

[0015] During inspection, the pipe is transported to the inspection position by the conveying mechanism 1, and then inspected by the visual inspection module 2. The operator does not need to operate, and the surface defects of the pipe are automatically detected, which is not prone to misjudgment, missed inspection, etc. During inspection, the rotating mechanism drives the pipe to rotate, so that the surface of the pipe can be fully inspected at one time, which is more convenient to operate.

[0016] Furthermore, the rotating mechanism includes a bracket 31, a worm gear 32, a worm 33, a motor 34 and a rotating frame 35. The worm gear 32 is rotatably mounted on the bracket 31, the worm 33 is rotatably mounted on the bracket 31 and engages with the worm gear 32, the motor 34 is fixedly mounted on the bracket 31 and connected to the worm 33, and the rotating frame 35 is fixedly connected to the worm gear 32. The bracket 31, the worm gear 32 and the rotating frame 35 are all provided with through holes for the pipe to pass through, and the rotating frame 35 is provided with a fixing mechanism for fixing the pipe.

[0017] Furthermore, the fixing mechanism includes two clamping rollers 41 and four pushing mechanisms for pushing the clamping rollers 41. Four slide grooves 42 are provided on the rotating frame 35.

The spring 44 is sleeved on the bolt 1 45 and one end contacts the cover plate 46, and the other end contacts the slide plate 43 to push the two clamping rollers 41 to clamp the pipe.

[0018] Four propulsion mechanisms, arranged in groups of two, are located at either end of the clamping rollers 41. Because the width of the connecting groove 48 is greater than that of the connecting block 47, the slide 43 has a certain amount of floating space. After the pipe enters between the two clamping rollers 41, the spring 44 pushes the clamping rollers 41 to clamp the pipe. The rotating frame drives the clamping rollers 41 to rotate, which in turn drives the pipe, allowing the visual inspection module 2 to inspect the entire circumference at once. During operation, the motor 34 drives the worm 33, which in turn drives the worm gear 32, which in turn drives the rotating frame 35, thereby rotating the pipe.

[0020] After the conveyor mechanism 1 delivers a long length of pipe, the end of the pipe extends between two support rollers 53. The support rollers 53 support the pipe to prevent damage due to localized excessive stress. The slider 55 and the chute can adjust the distance between the support rollers 53 to accommodate pipes of different diameters.

[0021] Furthermore, two pressing plates 56 are provided, and the two pressing plates 56 are arranged on the left and right sides of the second slide groove 54, so that the sliding block 55 is subjected to balanced force and the overall structure is more stable.

The lifting frame 62 is installed on the bracket 31 in a lifting manner, and the screw 61 is installed on the top of the bracket 31 in a rotatable manner. A nut is fixed on the lifting frame 62, and the screw 61 engages with the nut to drive the lifting frame 62 to move up and down. The rotating mechanism is installed on the lifting frame 62.

[0023] By setting the lifting mechanism, when detecting pipes of different diameters, the height of the rotating mechanism can be adjusted so that the pipe can be clamped exactly in the middle of the clamping roller 41, so that the pipe is evenly stressed when being clamped, and the overall structure will not be cheap and will be more firm and stable.
