[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1

[0031] The steel pipe rotating assembly 6 includes a translation plate 64 slidably installed on the top of the beam plate 3. A connecting opening 63 is penetrated and opened on both sides of the top of the beam plate 3 and directly below the translation plate 64. An electric telescopic rod 66 is installed on the top of the translation plate 64, and the movable end of the electric telescopic rod 66 passes through the translation plate 64 and the interior of the connecting opening 63 and is located below the beam plate 3. The movable end of the electric telescopic rod 66 is fixedly connected to a connecting column 67, and a clamping rotating body 68 is installed at the bottom end of the connecting column 67.

[0032] When the steel pipe is placed on the steel pipe lifting assembly 2, there is no need for manual control to move the steel pipe, so that workers are kept away from the steel pipe flaw detection station, avoiding close contact between workers and radiation, and improving the safety of detection.

[0033] Guide rails 62 are installed on both sides of the top of the crossbeam plate 3 and at the front and rear positions of the connecting port 63 , and sliders are installed at the front and rear positions of the bottom of the translation plate 64 , and the sliders slide on the guide rails 62 .

[0034] Linear motors 61 are installed at the front and rear positions of both sides of the top of the crossbeam plate 3 , side connecting plates 65 are welded at the front and rear positions of the top of the translation plate 64 , and the movable ends of the linear motors 61 are connected to the side connecting plates 65 .

[0037] Example 2

[0038] Reference Figure 1-5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0039] The clamping rotating body 68 includes a motor bin 681 welded to the bottom end of the connecting column 67, a driving motor B682 is installed inside the motor bin 681, a driving end of the driving motor B682 is fixedly connected to a rotating plate 683, a double-headed telescopic cylinder 684 is installed at the middle part of the rotating plate 683 facing the outside, and the movable ends on both sides of the double-headed telescopic cylinder 684 are installed with resistance blocks 685.

The arc-shaped rubber blocks 686 fit tightly against the inner wall of the steel pipe to reduce the gap when the resistance blocks 685 contact the inner wall of the steel pipe, so as to improve the clamping effect on the steel pipe.

[0041] A bracket is welded inside the motor compartment 681 and on the front side of the drive motor B682, and a ball bearing rotatably connected to the drive shaft end of the drive motor B682 is installed on the bracket. The bracket is used to support the drive shaft of the drive motor B682 and evenly distribute the force on the drive shaft of the drive motor B682 to ensure the stability of the use of the drive motor B682 and extend its service life.

[0042] The steel pipe is clamped by the abutment blocks 685 on both sides, and the driving motor B682 drives the rotating plate 683 to rotate, so that the steel pipe can be rotated. By rotating the steel pipe, the weld of the steel pipe can be photographed from multiple sides and angles to ensure the effect of flaw detection on the steel pipe.

[0043] The steel pipe lifting assembly 2 includes a U-shaped frame 21, and a roller 22 is rotatably installed inside the U-shaped frame 21. The outer wall of the U-shaped frame 21 has inclined surfaces on both sides, and the middle end is straight.

[0045] During use, according to the diameter of the steel pipe, the electric telescopic rod 66 is extended and retracted to drive the clamping rotating body 68 to move up and down, and the clamping rotating body 68 is moved to the height position at the center of the steel pipe. The linear motor 61 drives the side connecting plate 65 to drive the translation plate 64 to move, so that the clamping rotating body 68 moves left and right, and the interference block 685 is moved to the inside of the steel pipe. When the interference blocks 685 on both sides are respectively located at the two ends of the steel pipe, the extension of the interference blocks 685 causes the arc-shaped rubber block 686 to fit and contact the inner wall surface of the steel pipe. The steel pipe is clamped by the interference blocks 685 on both sides, and the driving motor B682 drives the rotating plate 683 to rotate, so that the rotation operation of the steel pipe can be realized.
