[0003] The current petrochemical pipeline surface coating spraying equipment has been found to have at least the following technical problems:

[0004] First, in the process of coating the surface of petrochemical pipelines, the existing coating spraying equipment requires the staff to constantly adjust the position of the petrochemical pipelines or coating nozzles, which is cumbersome to operate, increases time and labor costs, and has low automation, which reduces the efficiency of coating the surface of petrochemical pipelines;

[0015] (III) Beneficial effects

[0016] 1. The driven gear is driven to rotate by the rotation of the driving gear, and the table is driven to rotate by the rotation of the driven gear. The connecting column and the abutment plate are driven to rotate by the rotation of the table, so that the petrochemical pipeline can be driven to rotate.

[0038] Working principle:

[0039] The first step is to place the coating on the petrochemical pipeline arc support plate 8, start the servo motor 18, so that the two fixing components move closer to each other, so that the two connecting columns 2 are respectively inserted into the two ends of the petrochemical pipeline, and use the abutment plate 3 to expand outward to abut the inner wall of the pipeline to complete the limit fixation of the two ends of the petrochemical pipeline, start the spraying equipment body 7, so that the paint is sprayed from the paint nozzle 71 to the surface of the pipeline, start the servo motor 2 6, so that the driving gear 61 rotates, and the driven gear 62 rotates through the rotation of the driving gear 61, and the round table 1 rotates through the rotation of the driven gear 62, and the connecting gear 1 is driven to rotate through the rotation of the round table 1. The connecting column 2 and the abutment plate 3 rotate, thereby driving the petrochemical pipeline to rotate. By driving the petrochemical pipeline to rotate, the relative position between the petrochemical pipeline and the paint nozzle 71 can be changed, which can ensure that the paint is evenly sprayed on the pipeline surface. The servo motor 3 73 is used to control the spraying equipment body 7 and the paint nozzle 71 to move along the length direction of the petrochemical pipeline, so that the paint spraying of the entire pipeline can be achieved. In the process of spraying the paint on the petrochemical pipeline, there is no need for the staff to manually adjust the position of the petrochemical pipeline or the spraying equipment body 7, which reduces repeated operations at work, improves the spraying efficiency, saves time and labor costs, and has high automation.

[0040] In the second step, when the petrochemical pipeline needs to be fixed, the servo motor 18 is started to rotate the threaded rod 19, and the rotation of the threaded rod 19 will drive the two slides 52 to move closer to each other, and the two slides 52 to move closer to each other, and the two slides 52 to move closer to each other will drive the two push plates 5 to move closer to each other, and each push plate 5 is fixedly connected to the ring 51 through four springs 2 54, and the two push plates 5 to move closer to each other will drive the two rings 51 to move closer to each other, and the two rings 51 to move closer to each other will drive the two round tables 1 to move closer to each other, and the two round tables 1 to move closer to each other will drive the two connecting columns 2 to move closer to each other, so that the two connecting columns 2 are respectively inserted into the two ends of the petrochemical pipeline, and the opposite ends of the two round tables 1 are tightly fitted with the two ends of the petrochemical pipeline, and the two round tables 1 clamp and fix the petrochemical pipeline, and the two ends of the petrochemical pipeline are The two ends are respectively in the two circular rings 11. At this time, the two slide seats 52 are driven to continue to move, so that the two push plates 5 continue to move closer to each other, so that the spring 2 54 is compressed, so that the push plate 5 moves closer to the round table 1, and the push plate 5 applies a force to the fixed column 43, so that the fixed column 43 drives the round block 4 to move, and the movement of the round block 4 drives the three push blocks 41 to move, so that the three push blocks 41 respectively apply a force to the contact block 32, so that the three abutment plates 3 are respectively expanded outward, so that each abutment plate 3 is tightly against the inner wall of the petrochemical pipeline, and the two round tables 1 are used to clamp the two ends of the petrochemical pipeline, and the two groups of abutment plates 3 are used to clamp the inner wall of the petrochemical pipeline, so as to realize multiple and multi-node fixation of the petrochemical pipeline, which is more stable and convenient for the fixation of the petrochemical pipeline, so that the petrochemical pipeline can be stably driven to rotate, so as to spray the paint on the surface of the petrochemical pipeline;

[0041] The third step is that before the two fixed components move, that is, in the initial state, the upper surface of the rectangular support rod 91 is tightly fitted with the bottom surface of the fixed block 1 84, and the rectangular support rod 91 supports the arc support plate 8 and the cross slide block 82. The arc support plate 8 is used to support the placed petrochemical pipeline. When the push plate 5 and the slide seat 52 continue to move, the slide seat 52 will drive the connecting rod 9 to move, so that the connecting rod 9 drives the rectangular support rod 91 to move, so that the rectangular support rod 91 and the fixed block 1 84 are misaligned. The reset effect of the spring four 83 is used to make the bottom surface of the fixed block 1 84 fit with the upper surface of the fixed block 2 92, so that the arc support plate 8 moves down and no longer contacts the surface of the petrochemical pipeline, effectively preventing the petrochemical pipeline from rotating and contacting and rubbing with the surface of the arc support plate 8 when the petrochemical pipeline is sprayed with paint, causing the sprayed paint to be scraped off, ensuring the rationality of the structural design, and there is no need for the staff to manually adjust the position of the arc support plate 8, which is more convenient to use;

[0042] The fourth step is to fix four round rods 53 equidistantly on the circumference of the push plate 5, and each round rod 53 is movable through the collar 51 to avoid rotational offset between the collar 51 and the push plate 5. A limit ring 12 is fixedly installed on the truncated table 1, and a ring groove limit ring 12 is provided on the surface of the collar 51. The limit ring 12 is arranged in the ring groove, so that the truncated table 1 and the collar 51 can rotate relative to each other to avoid motion interference, and the structural design is reasonable.

[0043] In the fifth step, after the paint spraying of the petrochemical pipeline is completed, the two fixed components are reset, and the two push plates 5 no longer apply force to the fixed column 43. The reset effect of spring three is used to reset the round block 4, the push block 41 and the limit block 42, so that the push block 41 no longer applies force to the contact block 32. The reset effect of spring one 15 is used to reset the abutment plate 3 to the groove 21. At this time, the clamping of the abutment plate 3 on the inner wall of the pipeline is released, so that the connecting column 2 and the abutment plate 3 can be smoothly separated from the pipeline, and the two fixed components can be smoothly reset, so as to facilitate the subsequent continuous paint spraying of the petrochemical pipeline, which is more convenient to use.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
