[0028] A limiting cavity 19 is connected to one side of the rotating disk 23. A limiting block 20 is slidably installed inside the limiting cavity 19. A lifting handle block 17 is connected to the top of the limiting block 20. The lifting handle block 17 extends to the top of the rotating disk 23. A spring 18 is fitted at the connection between the upper surface of the limiting block 20 and the lifting handle block 17. The setting and cooperation of the lifting handle block 17, the spring 18, and the limiting cavity 19 can adjust the insertion state of the positioning rod 22 and the multiple positioning holes 21, so as to position the adjusted screw 2 and the height of the conveyor table 16, and avoid affecting the stability of the conveyor table 16.

[0029] The bottom of the limiting block 20 is connected to a positioning rod 22.

[0030] The top surface of bracket 3 is provided with equally spaced positioning holes 21 that match the positioning rod 22.

[0031] The device base 1 is connected to a movable groove 12 in the middle, and a screw 14 is connected to the middle of the movable groove 12. A gear plate 13 is fitted on the bottom surface of the screw 14. A bevel tooth 15 is engaged on one side of the top of the gear plate 13. A motor 10 is installed on one side of the bevel tooth 15. By setting up the lifting cylinder 11, movable groove 12, gear plate 13, screw 14, bevel tooth 15 and motor 10, and cooperating with the limiting slider 9 to slide along the limiting groove 8, the lifting cylinder 11 can be limited to move up and down along the screw 14 in a straight line.

The front and rear sides of the top of the two pressure plates 36 are hinged with tension springs 35. The expansion and recovery of the tension springs 35 enable the two pressure plates 36 to be automatically adapted to different specifications of welded pipes, thus improving practicality.

[0037] The upper ends of both tension springs 35 are hinged to the front and rear sides of the lower surface of the connecting plate 31.

[0038] In this embodiment, the rotating disk 23, screw 1 2, and moving block 26, in conjunction with the sliding action of the limiting slider 27 along the limiting groove 25, limit the linear movement of the auxiliary moving block 26 along the screw 1 2, allowing for individual adjustment of the height of the two conveyor platforms 16.

This allows for arbitrary control of the distance between the conveyor platform 16 and the welding head 5. The lifting handle block 17, spring 18, and limiting cavity 19, when used in conjunction, allow for adjustment of the insertion state of the positioning rod 22 and multiple positioning holes 21, facilitating the positioning of the adjusted screw 1 2 and the height of the conveyor platform 16.
