A transmission belt 12 is sleeved at the connection between the first motor 15 and the active roller 14;

[0038] During use, place the drill pipe between the passive roller 13 and the active roller 14. Then start the first motor 15 to drive the active roller 14 to rotate. The active roller 14 drives the drill pipe to perform a circular motion. At this time, the operator holds the flaw detection probe to perform a non-destructive flaw detection test on the drill pipe;

[0039] Retracting and extending assembly: The retracting and extending assembly includes a second motor 21, a rotating rod 22, a guide rod 23, a frame 24, an X-shaped frame 25, a mounting frame 26, a slider 27, and a guide groove 28;

The rotating rod 22 is rotatably connected to the center of the inner wall of the frame 24. The X-shaped frame 25 is rotatably connected to both sides of the inner wall of the chassis 11. Both ends of the guide rod 23 are fixedly connected to the inner side of the front end of the X-shaped frame 25. The mounting frame 26 is rotatably connected to the top end of the X-shaped frame 25. The slider 27 is fixedly connected to one end inner wall of the X-shaped frame 25. The guide groove 28 is slidably connected to both sides of the front end of the mounting frame 26;

[0041] The second motor 21 is used for installing and connecting the rotating rod 22, providing a sliding space for the guide rod 23 through the rotating rod 22, and at the same time limiting the sliding range of the guide rod 23 through the setting of the frame 24. Both ends of the guide rod 23 are fixedly connected to the inner wall of the lower end of one side of the X-shaped frame 25. At the same time, both upper ends of the X-shaped frame 25 are rotatably connected to both sides of the rear end of the mounting frame 26. The mounting frame 26 is used for opening the guide groove 28 and providing a sliding space for the slider 27 through the guide groove 28;

[0042] Through the auxiliary cooperation between the rotating rod 22 and the guide rod 23, a guiding sliding force can be provided for the guide rod 23 threadedly connected to the outside of the rotating rod 22, and at the same time, a turning force can be provided for the X-shaped frame 25, enabling the X-shaped frame 25 to change from a folded state to an unfolded state, thereby providing an upward force for the mounting frame 26.

[0043] Working principle: When using the transmission device for non-destructive flaw detection;

[0044] First, start the second motor 21 to work, so that the output shaft of the second motor 21 drives the rotating rod 22 to rotate through a coupling. Since the guide rod 23 and the rotating rod 22 are arranged on the same central axis, the guide rod 23 can be guided and slide along the thread track of the rotating rod 22;

[0045] Next, the slider 27 is guided to slide along the inside of the guide groove 28, so that the X-frame 25 is extended from the folded state to the unfolded state, which can provide a stable upward force for the mounting frame 26;

[0046] After the transmission device for nondestructive testing is used in this step, it can be retracted and protected, reducing the damage caused by the external influence on the transmission device for nondestructive testing and extending the service life of the transmission device for nondestructive testing.

[0047] Please refer to Figures 1-4 As shown, in this embodiment, on the basis of the above-mentioned Embodiment 1, there is also a protection component;

[0048] The protection component includes a connecting rod 31, a rotating gear 32, a connecting block 33, and a protection cover 34;

[0050] The connecting rod 31 is used to fixedly connect the protection cover 34 and can provide the power for the protection cover 34 to flip by being fixedly connected to one side of the inner wall of the rotating gear 32 at both ends. The rear side of the connecting block 33 is fixedly connected to the front and rear ends of the mounting frame 26;

[0051] Through the meshing cooperation between the connecting block 33 and the rotating gear 32, when the connecting block 33 rises, the meshing can be released and the rotational driving force can be provided, which can provide a stable flipping power for the protection cover 34;

[0052] Working principle: When the transmission device for nondestructive testing is in use;

[0053] First, when the mounting frame 26 is guided to rise, the connecting block 33 can be guided to slide, so that the rotating gear 32 engaged on one side rotates;

[0054] Next, the connecting rod 31 is rotated, so that the protection cover 34 is horizontally flipped and the blocking protection provided for the top of the chassis 11 is released;

[0055] This step can provide a protection and shielding function for the transmission device during lifting and use, facilitating the operation and use by the staff.
