[0027] In summary, the working principle of the heavy steel continuous paint spraying treatment system and method is as follows: before use, first, the spraying elbow frame 11 is matched with the external paint spraying machine, the operation of the external paint spraying machine provides paint for the spraying elbow frame 11, then the control power supply and integrated control circuit are matched and installed for the first servo motor 9, the electromagnet 16, the first electric telescopic rod 22, the second electric telescopic rod 23, the third electric telescopic rod 45 and the second servo motor 48, realizing the power supply and operation control of the first servo motor 9, the electromagnet 16, the first electric telescopic rod 22, the second electric telescopic rod 23, the third electric telescopic rod 45 and the second servo motor 48, when the heavy steel profile 1 is sprayed, the first servo motor 9 is powered and operated to realize the rotation driving of the second mounting arm 8 relative to the second mounting frame 3, due to the mutual meshing of the two counter rotating gears 6 and the transmission of the second linkage arm 7, the first mounting arm 4 and the first linkage arm 5 will synchronously rotate relative to each other, when the second mounting arm 8 is controlled to rotate by the first servo motor 9, the first mounting arm 4 will be driven to move by the first linkage arm 5, due to the transmission of the second linkage arm 7, the relative distance between the first mounting frame 2 and the second mounting frame 3 can be adjusted, and the relative adjustment of the two spraying elbow frames 11 can also be realized, the first mounting frame 2 and the second mounting frame 3 are controlled to move away from each other, until the distance between the two spraying elbow frames 11 is sufficient to allow the heavy steel profile 1 to pass through, then the two second servo motors 48 in the power wheel assembly are powered and operated, the output shaft of each second servo motor 48 is provided with a synchronous driving pulley, the axle of each traveling wheel 47 is provided with a synchronous transmission pulley, the two synchronous driving pulleys are transmissionally connected with synchronous belts, and the two synchronous belts are transmissionally connected with the two synchronous transmission pulleys, realizing the coordinated rotation of the two traveling wheels 47, and then realizing the adjustment operation of the traveling and turning of the vehicle body structure, so as to realize the position adjustment of the heavy steel continuous paint spraying treatment system relative to the heavy steel profile 1, so that the heavy steel profile 1 enters the lower side of the vehicle body structure, then the first servo motor 9 is powered and operated again to realize the reduction of the relative distance between the first mounting frame 2 and the second mounting frame 3, so that the two spraying elbow frames 11 have a suitable spraying distance relative to the heavy steel profile 1, then the paint spraying machine is started, the power wheel assembly is started at the same time when the paint spraying machine is operated to connect the atomized paint to the spraying elbow frame 11, so that the spraying elbow frame 11 can move relative to the heavy steel profile 1, realizing the continuous spraying operation of the heavy steel profile 1.

[0028] Further, in the spraying process, the electromagnetic field generated by the electromagnet 16 is adjusted and controlled by energizing the electromagnet 16 and controlling the size of the current. When the electromagnet 16 is powered on, it acts on the follower column 17. The follower column 17 is a material that can be magnetically attracted by the electromagnetic field generated by the electromagnet 16. Therefore, when the electromagnet 16 is powered on, it will form a pulling force on the follower column 17, allowing the follower column 17 to overcome the elastic force of the disc spring 20 and move relative to the branch pipe 15. Finally, the position of the atomizing disc holder 19 is adjusted to control the gap between the atomizing disc holder 19 and the branch pipe 15, guide and further atomize the paint sprayed from the branch pipe 15, and control the paint spraying effect. When the target heavy steel profile 1 is in a lying state, the first electric telescopic rod 22 is powered on to drive the outer extension hinge seat 24. The outer extension hinge seat 24 is stressed to drive the side turning frame 21 to rotate relative to the first mounting frame 2, and then drive the side pushing cylinder 25 to move, so that the side pushing cylinder 25 is adjusted relative to the heavy steel profile 1 and the heavy steel profile 1 is assisted to push. The second electric telescopic rod 23 is powered on to push the lifting seat 26. Since the elastic force of the second elastic spring 30 is greater than that of the first elastic spring 29, when the second electric telescopic rod 23 pushes the lifting seat 26 to fall relative to the side pushing cylinder 25, the first elastic spring 29 is compressed at the initial stage, and the installation cylinder 27 falls relative to the side pushing cylinder 25 at the initial stage. When the elastic compression force of the first elastic spring 29 increases to overcome the elastic compression of the second elastic spring 30, the second elastic spring 30 is compressed. Due to the threaded connection between the lifting cylinder 28 and the side pushing cylinder 25, the lifting cylinder 28 rotates synchronously when it falls relative to the side pushing cylinder 25. The rotating lifting cylinder 28 drives the installation cylinder 27 to rotate synchronously, so that the insertion holder 31 at the bottom of the installation cylinder 27 is driven to rotate. The second electric telescopic rod 23 should be operated to push the lifting seat 26 to fall after the first electric telescopic rod 22 drives the side pushing cylinder 25 to rotate and adjusts the heavy steel profile 1 to tilt. When the second electric telescopic rod 23 works to rotate the insertion holder 31, the end of the heavy steel profile 1 close to the insertion holder 31 has a space to allow the insertion holder 31 to be inserted. The principle is as follows Figure 16As shown, the second electric telescopic rod 23 runs to control the support rotating wheel 34 to form support on the raised part of the heavy steel section 1, and to achieve parking, if necessary, the first electric telescopic rod 22 can run to control the side pushing cylinder 25 to form a small turning away from the heavy steel section 1, to facilitate the support rotating wheel 34 to form complete support on the heavy steel section 1, when the support rotating wheel 34 forms complete support on the heavy steel section 1, the ground contact rotating wheel 33 should be controlled to form support contact with the ground, and then the heavy steel section 1 is in an inclined state, in which the contact area of the heavy steel section 1 with the ground is small, which can improve the single spraying coverage of the heavy steel section 1, as shown in the attached Figure 17 As shown, the second electric telescopic rod 23 runs to control the support rotating wheel 34 to form support on the raised part of the heavy steel section 1, and to achieve parking, if necessary, the first electric telescopic rod 22 can run to control the side pushing cylinder 25 to form a small turning away from the heavy steel section 1, to facilitate the support rotating wheel 34 to form complete support on the heavy steel section 1, when the support rotating wheel 34 forms complete support on the heavy steel section 1, the ground contact rotating wheel 33 should be controlled to form support contact with the ground, and then the heavy steel section 1 is in an inclined state, in which the contact area of the heavy steel section 1 with the ground is small, which can improve the single spraying coverage of the heavy steel section 1, as shown in the attached

[0029] Further, in the process of the first servo motor 9 running to realize the adjustment of the first mounting arm 4 and the second mounting arm 8, the relative distance between the vertical spraying pipes 14 in the two spraying elbow frames 11 will form a relative adjustment, so that the branch pipes 15 on the two vertical spraying pipes 14 have a suitable spraying distance relative to the heavy steel profile 1. Since the atomized paint sprayed from the branch pipes 15 will form a certain range of coverage, in the process of the vertical spraying pipes 14 swinging the branch pipes 15 due to adjustment, the branch pipes 15 can provide good spraying effect on the heavy steel profile 1 within a certain range. In the foregoing adjustment process, the horizontal spraying pipe 13 is always at the same height. Considering that the horizontal spraying pipe 13 is mostly in a top-to-bottom spraying operation, the atomized paint sprayed will be affected by gravity to facilitate falling, so the distance requirement of the horizontal spraying pipe 13 for the heavy steel profile 1 is lower. Therefore, in this scheme, the first mounting frame 2 and the second mounting frame 3 are not designed to be adjustable in height. However, if height adjustment of the horizontal spraying pipe 13 is required in actual use, the first mounting frame 2 and the second mounting frame 3 can also be designed to have a lifting function to achieve the purpose of height adjustment of the horizontal spraying pipe 13. In the process of the first servo motor 9 running to realize the adjustment of the relative distance between the first mounting frame 2 and the second mounting frame 3, in order to reduce the load of the first servo motor 9, the second servo motor 48 can be run at the same time to make the traveling wheel 47 roll relative to the ground to reduce the interaction force between the traveling wheel 47 and the ground. Therefore, the driving force required to overcome the movement of the traveling wheel 47 relative to the ground is also reduced when the traveling wheel 47 is in a rolling state.
