An inner part of the annular cylinder body 1 is provided with a placement part for placing magnetic tiles. The placement part includes two groups of placement plates 4. The two groups of placement plates 4 are symmetrically arranged inside the annular cylinder body 1 and extend along the height direction of the annular cylinder body 1. An inner wall of the annular cylinder body 1 is provided with a housing 3 in the height direction. One side of the housing 3 close to the placement plate 4 is provided with an ultrasonic flaw detector probe 34. The ultrasonic flaw detector probe 34 is slidably arranged along the axial direction of the housing 3. One end of the annular cylinder body 1 is provided with a rotation assembly for driving the housing 3 to rotate circumferentially along the annular cylinder body 1.

[0020] In an optional embodiment: a first driving motor 31 is installed on one side inside the housing 3. An output shaft of the first driving motor 31 is fixedly connected with a nut block 33. The other end of the nut block 33 is rotatably connected with the other side inside the housing 3. A threaded rod 32 is threadedly connected to the nut block 33. An activity port 30 is opened on one side of the housing 3 close to the placement plate 4. The activity port 30 is opened along the axial direction of the housing 3. One end of the ultrasonic flaw detector probe 34 is fixedly connected with the nut block 33. The nut block 33 is slidably connected to the activity port 30. When the first driving motor 31 is started, the ultrasonic flaw detector probe 34 can be driven by the nut block 33 to move in the axial direction of the housing 3.

[0021] In an optional embodiment: a base 2 is arranged at the bottom of the annular cylinder body 1. One ends of the two placement plates 4 far from the rotation assembly are connected through a U-shaped frame 41. The U-shaped frame 41 is fixedly connected with the base 2 through a vertical rod 42, so that the two placement plates 4 can be stably connected inside the annular cylinder body 1.

[0022] In an optional embodiment: the two placement plates 4 are both inclined. The included angle between the placement plate 4 and the horizontal plane is between 120° and 150°. In this way, both sides of the magnetic tile to be detected can be placed more stably on the placement plate 4.

[0023] In an alternative embodiment: The rotating assembly includes a second driving motor 5, a fixed mounting plate 51, and a rotating rod 52. The second driving motor 5 is fixedly mounted on the fixed mounting plate 51. One end of the rotating rod 52 is connected to the output shaft of the second driving motor 5, and the other end of the rotating rod 52 is fixedly connected to the housing 3. The side of the housing 3 close to the annular cylinder 1 is adapted to the inner sidewall of the annular cylinder 1 and is in contact with the inner sidewall of the annular cylinder 1. When the housing 3 is rotated, the housing 3 can be rotated more stably. Specifically, the present application further includes a controller and a display. The first driving motor 31, the ultrasonic flaw detector probe 34, the second driving motor 5, and the display are all electrically or wirelessly communicatively connected to the controller. The detection data of the magnetic tile detected by the ultrasonic flaw detector probe 34 is conveniently displayed through the display.

[0024] Specifically, when detecting the defects of the magnetic tile to be detected, first place the magnetic tile on the two placing plates 4. After the placement is completed, first operate the first driving motor 31 to drive the ultrasonic flaw detector probe 34 connected to the nut block 33 to move to one side of the magnetic tile, then start the ultrasonic flaw detector probe 34, and then start the first driving motor 31 to gradually drive the ultrasonic flaw detector probe 34 to move in the length direction of an area of the magnetic tile, so that the ultrasonic flaw detector probe 34 can comprehensively detect this area. After the detection of this area is completed, the ultrasonic flaw detector probe 34 on the housing 3 is rotated to align with the next area of the magnetic tile through the rotating assembly, and then the above steps are performed to comprehensively detect this area, so that the entire area of the magnetic tile can be effectively and comprehensively detected, improving the inspection effect and efficiency.

[0025] When the ultrasonic flaw detector probe 34 is rotated and adjusted to be close to the side of the magnetic tile, the part of the side of the magnetic tile that is not blocked by the placing plate 4 can be detected first. When the inspection is completed, only axially move the magnetic tile so that the side of the magnetic tile that was previously blocked by the placing plate 4 is no longer blocked, and the side area of the magnetic tile can be effectively detected.

[0026] Moreover, through the present application, it is not necessary to flip and adjust the position of the magnetic tile and clamp it to detect the other side of the magnetic tile, which saves time and effort and improves the detection efficiency of the magnetic tile.

[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
