Detailed implementation manners
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model.
[0020] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a traffic guardrail plasma welding machine, which includes a welding machine body 1. One side of the welding machine body 1 is fixedly installed with a connecting wire 3. One end of the connecting wire 3 is fixedly installed with a welding torch 2. Both sides of the front part of the welding machine body 1 are fixedly connected with connecting plates 4. One side of the connecting plate 4 on the right side is fixedly connected with a motor 5. The motor 5 is a servo motor, electrically connected to an external power supply and controlled by a control switch. The output shaft of the motor 5 is fixedly connected with a threaded rod 6 through a coupling. One end of the threaded rod 6 is rotatably connected to one side of the left connecting plate 4 through a bearing. The outer surface of the threaded rod 6 is threadedly connected with a threaded sleeve 7. A chute 8 is opened in the front part of the welding machine body 1. The inside of the chute 8 is slidably connected to the outer surface of the threaded sleeve 7 through a slider. The front part of the outer surface of the threaded sleeve 7 is fixedly connected with an electric telescopic rod 9 through a fixing plate. The electric telescopic rod 9 is electrically connected to an external power supply and controlled by a control switch. The telescopic end of the electric telescopic rod 9 is fixedly connected with a mounting plate 10. A plurality of limiting holes 11 adapted to the welding torch 2 are opened at the top of the mounting plate 10.
[0021] Further, in order to adjust the position of the welding torch 2 and limit it, one side of the mounting plate 10 is fixedly connected with a limiting frame 12. One side of the limiting frame 12 is fixedly connected with a sliding cylinder 13. A sliding rod 14 is slidably connected inside the sliding cylinder 13. One end of the sliding rod 14 is fixedly connected with a limiting plate 16 adapted to the welding torch 2. A first spring 15 is fixedly connected between the outer surfaces of the sliding cylinder 13 and the sliding rod 14 and between the limiting frame 12 and the limiting plate 16.
[0022] Further, in order to prevent the connecting wire 3 from getting entangled, one side of the top of the welding machine body 1 is fixedly connected with a support plate 18. One side of the support plate 18 is fixedly connected with a second spring 19. One end of the second spring 19 is fixedly connected with a pulling plate 20 adapted to the connecting wire 3.
[0023] It should be noted that when the electric telescopic rod 9 drives the welding torch 2 to move downward, the welding torch 2 will pull the connecting wire 3 to extend, and the connecting wire 3 will drive the second spring 19 to stretch through the pulling plate 20. When the electric telescopic rod 9 drives the welding torch 2 to move upward, through the action of the second spring 19, the pulling plate 20 pulls the connecting wire 3 to be stored to prevent entanglement.
[0024] Further, in order to facilitate the movement of the welding machine body 1, pulleys 17 are fixedly connected to the four corners of the bottom of the welding machine body 1.
[0025] During use, place the traffic guardrail in front of the welding machine body 1. By pulling the limit plate 16 to the right, the limit plate 16 no longer presses the welding torch 2. Insert the welding torch 2 into the adapted limit hole 11, and under the action of the first spring 15, the sliding cylinder 13 and the sliding rod 14 push the limit plate 16 to limit the welding torch 2 in the limit hole 11 again. Then control the extension electric telescopic rod 9, and the electric telescopic rod 9 will drive the mounting plate 10 to move downward, and the mounting plate 10 will drive the welding torch 2 to move downward to align the welding torch 2 with the welding position of the guardrail.
[0026] By controlling the motor 5 to drive the threaded rod 6 to rotate, the threaded rod 6 will drive the threaded sleeve 7 to move, so that the threaded sleeve 7 drives the welding torch 2 to move through the electric telescopic rod 9 and the mounting plate 10. At the same time, control the welding torch 2 on the welding machine body 1 to weld the guardrail, so that the welding torch 2 continuously moves to weld the guardrail.
