The side of the moving column 2 located on the side of the first synchronous wheel 8 is fixedly connected to the mounting seat 9, and the middle part of the mounting seat 9 is fixedly connected to the motor 10. The output end of the motor 10 is fixedly connected to the second synchronous wheel 11. The second synchronous wheel 11 and the first synchronous wheel 8 are connected by a synchronous belt 12. One end of a group of rotating shafts 5 passes through the moving column 2, and the end of the rotating shaft 5 passing through the moving column 2 is fixedly connected to the first synchronous wheel 8.

[0028] Working principle: When in use, the support column 1 is installed at the four corners of the conveying mechanism, and the push plate 19 and the anti-collision plate 20 are pushed to move by the second cylinder 18, so that the anti-collision plates 20 at both ends of the steel pipe push the steel pipe to move, so that the anti-collision plates 20 push the two ends of the steel pipe to align, thereby making the arrangement of the steel pipe more neat, and the first cylinder 13 drives the moving column 2 to move downward, so that the rubber plate 17 is pressed on the upper end of the steel pipe, thereby fixing the position of the steel pipe, the motor 10 drives the rotating shaft 5 to rotate through the first synchronous wheel 8, the second synchronous wheel 11 and the synchronous belt 12, and the rotating shaft 5 drives the conveyor belt 14 to rotate through the roller 6, and the rubber plate 17 moves with the conveyor belt 14 in a cycle, and the rubber plate 17 moves with the steel pipe, thereby preventing the steel pipe from deviating during the movement, and each steel pipe that has just entered the conveying mechanism is circulated to The rubber plate 17 at one end of the conveyor belt 14 is pressed to limit the position of the steel pipe. Then the rubber plate 17 moves synchronously with the steel pipe, so that the steel pipe will not deviate during the transmission process. The motor 10 drives the conveyor belt 14 to rotate at the same speed as the speed of conveying the steel pipe. The rubber plate 17 and the anti-collision plate 20 can increase the friction between the limit plate 16 and the push plate 19 and the steel pipe, and at the same time avoid collision between the limit plate 16 and the push plate 19 and the steel pipe. When the transmission is completed, the motor 10 stops rotating, the first cylinder 13 pushes the moving column 2 upward, and the moving column 2 pushes the rotating shaft 5 upward. The rotating shaft 5 moves upward with the roller 6 and the conveyor belt 14. The limiting ring 7 can act as the conveyor belt 14, so that the position of the conveyor belt 14 will not change, and the second cylinder 18 will retract the push plate 19 and the anti-collision plate 20.
