[0028] The principle of the present invention is as follows: the guardrail body is transported on the transport platform 2 , and the transport motor 14 works, so that the transport wheel 3 rotates, that is, the positioning transfer is performed by the transport wheel 3 .

[0029] The operator hangs the arc tube on the suspension shaft 19. Since the arc tube is a symmetrical structure, when the suspension is stable and stationary, the arc area of ​​the arc tube contacts the top of the suspension shaft 19, and the straight tube areas on both sides are respectively located on both sides of the suspension shaft 19; the vibration of the suspension shaft 19 is controlled by the vibrator 8 so that the arc tubes are arranged in sequence on the suspension shaft 19 without crossing; the motor 29 is operated to move the guide rod 4 30 and the screw rod 4 31, that is, the clamping table 32 moves and approaches the position of the arc tube, and the motor 37 is controlled to work to move the rack 35 and the push seat 33, and the push seat 33 contacts the top area of ​​the suspension shaft 19 to push the arc tube, that is, to fit the arc tubes in sequence and eliminate the gaps, so that the arc tubes are neatly arranged on the suspension shaft 19.

[0030] Furthermore, by operating the motor 20, the screw rod 22 rotates, causing the straightening movable slide 23 to slide, so that the straightening limit rods 25 are located on both sides of the straight tube area on the arc tube, that is, the straight tube area is located between the straightening limit rods 25, and by operating the motor 3 27, the screw rod 3 28 rotates, causing the slide 2501 to move. Among the four straightening limit rods 25, each two straightening limit rods 25 form a group, which respectively perform straightening operations on the straight tube area. Specifically, the straightening limit rods 25 limit the straight tube area, and the straightening lifting electric cylinder 24 controls the lifting and movement of the movable platform 26, that is, the straightening limit rods 25 move along the straight tube area to complete the straightening, that is, the deflection of the straight tube area on the arc tube is straightened, which is beneficial to subsequent welding operations.

[0031] Furthermore, after the straightening operation is completed, the position of the clamping platform 32 is controlled to be located at the front end of the arc tube, and the push wheel 43 is controlled to move by pushing the electric cylinder 38. The push wheel 43 pushes the pushing inclined seat 44, and then the clamping seat 39 slides. The clamping seat 39 supports the straight tube area of ​​the arc tube, and the clamping plate 42 is controlled by the clamping electric cylinder 41 to clamp the straight tube area, and then the arc tube is transferred. During the movement, the arc tube is located above the flattening mechanism, and the control electric cylinder 10 controls the flattening mounting platform 11 to move, and the flattening motor 12 drives the flattening part 13. The flattening part 13 flattens the bottom end of the straight tube area, which is beneficial to the subsequent docking.

[0032] Then the arc tube is transferred to the top of the guardrail body, and the motor 4 works and the screw rod 5 rotates to make the lifting platform 18 move up and down, so that the bottom end of the straight tube area is in contact with the guardrail body, and automatic welding is performed by the automatic welding arm 2 17 and the automatic welding arm 1 16, that is, the arc tube is finally welded and fixed to the guardrail body.
