Tooth grooves 805 are evenly provided on the outer wall of the rotating ring frame 804, and a gear 806 is meshed and connected on one side of the tooth groove 805. The gear 806 is coaxially fixedly connected to the output shaft of the motor 807, and the motor 807 is fixedly installed on one of the transverse frames 801. An annular groove 812 is provided inside the rotating ring frame 804, and the annular groove 812 runs through the side of the rotating ring frame 804 close to the shot blasting box 4. A rotating semi-ring 817 is installed inside the annular groove 812, and the arc of the rotating semi-ring 817 is greater than one hundred and eighty degrees. A slide groove 803 is provided at the top of the transverse frame 801, and one end of the slide groove 803 is connected to the arc-shaped limit groove 802. The two ends of the rotating semi-ring 817 can slide in the slide grooves 803 on the two transverse frames 801. The two arc-shaped limit grooves 802 are provided with a first through groove 810 on the side close to each other. A second through groove 813 is provided on the inner side of the annular groove 812, and the second through groove 813 corresponds to the first through groove 810. A hanger 814 is symmetrically installed on the inner side wall of the rotating semi-ring 817, and a third cylinder 815 is installed on the hanger 814. The output ends of the two third cylinders 815 are on the side close to each other. A clamping plate 816 is installed on the output end of the third cylinder 815, and the clamping plate 816 is located on the central axis of the rotating ring frame 804. 817 is located in the annular groove 812 on the rotating ring frame 804, and the two ends of the rotating half ring 817 can slide in the slide groove 803. When the clamping plate 816 clamps the steel pipe, the rotating ring frame 804 rotates to drive the steel pipe to rotate, which is convenient for circumferential cleaning of the steel pipe. When the rotating half ring 817 moves toward the shot blasting box 4 to clamp the steel pipe and then moves back, it drives the steel pipe to move the distance of a single cleaning length of the steel pipe, avoiding repeated cleaning of the steel pipe part that has been cleaned, thereby improving the cleaning efficiency. A limiting ring groove 820 is provided inside the rotating half ring 817. The cross section of the limiting ring groove 820 is convex. One side of the limiting ring groove 820 passes through the side of the rotating half ring 817 close to the shot blasting box 4. The end of the horizontal frame 801 close to the shot blasting box 4 is equipped with a second cylinder 811. The output end of the cylinder 811 extends into the interior of the slide groove 803, and the output end of the second cylinder 811 is inserted into the interior of the limiting ring groove 820. The output end of the second cylinder 811 is fixedly installed with a limiting block 821, and the limiting block 821 is arranged inside the limiting ring groove 820. A positioning block 818 is installed at an equal angle on the side of the rotating semi-ring 817 away from the shot blasting box 4. The positioning block 818 is clamped in the interior of the positioning groove 819. The positioning groove 819 is opened on the inner wall of the annular groove 812. A fixed platform 808 is provided below the transverse frame 801. The fixed platform 808 is fixedly installed on the side wall of the support frame 1. Two first cylinders 809 are symmetrically installed on the top of the fixed platform 808. The output end of the first cylinder 809 is fixedly connected to the bottom wall of the transverse frame 801.A convex-shaped limiting ring groove 820 is provided on the rotating half ring 817, and the limiting block 821 on the output end of the second cylinder 811 is located in the limiting ring groove 820. When rotating, the limiting block 821 is fixed in position to limit the rotating half ring 817, ensuring that the rotating half ring 817 is always in the annular groove 812. At the same time, when the second cylinder 811 moves back, the rotating half ring 817 can be pulled along the slide groove 803 by the limiting block 821, which is convenient for driving the steel pipe to move. The arc of the rotating half ring 817 is greater than 180 degrees. The limiting block 821 is located in the limiting ring groove 820 and is fixed in position. Therefore, during the rotation of the rotating ring frame 804, it can be ensured that there is at least one limiting block 821 located in the limiting ring groove 820, thereby improving the rotation stability of the rotating half ring 817 and the cleaning stability of the steel pipe.
[0028] Working principle: When working, first place the steel pipe above the support roller 3, so that the steel pipe enters the shot blasting box 4, and then open each shot blasting machine 5, so that the steel shot is ejected downward from the shot blasting port of the shot blasting machine 5 to polish and clean the surface of the steel pipe. Multiple shot blasting machines 5 are set to clean the surface of the steel pipe within a certain length.
[0029] When installing the steel pipe, the first cylinder 809 is turned on to push the horizontal frame 801 to move longitudinally, so that the rotating ring frame 804 and the steel pipe are coaxially arranged. At this time, the two clamping plates 816 are just on both sides of the steel pipe axis. The third cylinder 815 is turned on to move the two clamping plates 816 toward the steel pipe to clamp the steel pipe. When cleaning the surface of a length of steel pipe, the motor 807 is turned on to make the gear 806 rotate slowly, and the gear 806 is meshed with the tooth groove 805 on the outer wall of the rotating ring frame 804, thereby driving the rotating ring frame 804 to rotate slowly, and the rotating half ring 817 is clamped with the rotating ring frame 804, thereby driving the rotating half ring 817 to rotate with the rotating ring frame 804, thereby driving the steel pipe to rotate slowly, so as to perform shot blasting cleaning on the circumference of the steel pipe;
[0030] During the rotation process, since the limit block 821 on the output end of the second cylinder 811 is located inside the limit ring groove 820, it can be ensured that during the rotation of the rotating ring frame 804, the rotating half ring 817 is located in the annular groove 812, thereby improving the rotation stability of the steel pipe, and the arc of the rotating half ring 817 is greater than 180 degrees, so that during the rotation of the rotating half ring 817 with the rotating ring frame 804, at least one limit block 821 is located in the limit ring groove 820 for limiting;
[0031] When a section of the steel pipe is cleaned circumferentially, the rotating ring frame 804 is rotated back to its original state, the output end of the third cylinder 815 is controlled to retract, so that the clamping plate 816 no longer clamps the steel pipe, and the output end of the second cylinder 811 is controlled to retract, and the two ends of the rotating semi-ring 817 are pulled to move along the slide grooves 803 at the top of the two horizontal frames 801. When the single steel pipe cleaning length is moved, the second cylinder 811 is controlled to stop, and the third cylinder 815 is turned on so that the two clamping plates 816 clamp the steel pipe, and the rotating semi-ring 817 is pushed back into the annular groove 812 by the second cylinder 811, thereby pulling the steel pipe to move. At this time, the cleaned part of the steel pipe moves to the outside of the shot blasting box 4, and the subsequent part enters the shot blasting box 4, so as to avoid repeated cleaning of the cleaned steel pipe part and improve the cleaning efficiency.
