[0030] Reference Figure 1-Figure 3The automatic marking device for the drill rod inspection and maintenance line provided by the utility model is applied to the drill rod inspection and maintenance line to perform color ring spraying, steel grade spray printing and laser marking of the drill rod. The drill rod inspection and maintenance line includes a first workbench 1, a second workbench 2 and a conveying roller group 7 located between the first workbench 1 and the second workbench 2 for conveying the drill rod 10. The first workbench 1 and the second workbench 2 are both provided with conveying belts, so that the drill rod can also be moved on the first workbench 1 and the second workbench 2, and overall flaw detection is performed at the conveying roller group 7.

[0031] The first process on the first workbench 1 is a cleaning process, followed by a female head flaw detection process. A first roller and a second roller used in conjunction with a female head flaw detection component 8 are provided at the end of the first workbench 1. The drill rod 10 after cleaning is transported between the first roller and the second roller, and the female head portion of the drill rod 10 is aligned with the female head flaw detection component 8. The female head flaw detection component 8 performs flaw detection on the female head position of the drill rod 10, and through the rotation of the first roller and the second roller, the drill rod 10 is rotated by a certain angle to cooperate with the female head flaw detection component 8 to achieve multi-position and all-round female head flaw detection.

[0032] The first rotating roller includes a first rotating shaft 101, and a plurality of first disks 102 are fixedly connected to the first rotating shaft 101 at equal intervals, so that a first installation area is formed between two adjacent first disks 102. The second rotating roller includes a second rotating shaft 103, and a plurality of second disks 104 are fixedly connected to the second rotating shaft 103 at equal intervals, so that a second installation area is formed between two adjacent second disks 104, and the first installation area is aligned with the second installation area.

[0033] The drill rod 10 is supported and driven to rotate by the rotating first plate 102 and the second plate 104 .

[0034] The automatic marking device of the drill pipe inspection and maintenance line includes: a color ring spraying component 3 and a steel grade printing component 4. The color ring spraying component 3 is used for spraying color rings. The color ring spraying component 3 can be set into two groups, which are respectively used for unit-attributed color ring spraying and steel grade color ring spraying. The steel grade printing component 4 is used for spraying steel grade identification on the drill pipe.

[0035] The color ring spraying assembly 3 includes: a first frame 301, one end of the first frame 301 is fixedly connected to the bottom of the first workbench 1, a first inverted U-shaped frame 302 and a second inverted U-shaped frame 303 are fixedly connected to the top of the first frame 301, the first inverted U-shaped frame 302 is located in the first installation area, and is rotatably connected to the first rotating shaft 101, the first inverted U-shaped frame 302 is fixedly connected to the air-drying assembly 304, the second inverted U-shaped frame 303 is located in the second installation area, and is rotatably connected to the second rotating shaft 103, and the second inverted U-shaped frame 303 is fixedly connected to the spray gun 305.

[0036] By relying on the fixed connection between the first frame 301 and the bottom of the first workbench 1 and the suspension of the first inverted U-shaped frame 302 and the second inverted U-shaped frame 303, the first frame 301 can be installed very stably. The spray gun 305 is equipped with an external paint pressure barrel and an air source. When the spray gun 305 dispenses paint, a color ring is formed as the drill rod rotates. Moreover, since the position where the spray gun 305 sprays on the drill rod is directly opposite to the first installation area and the second installation area, the color ring will not be scratched when the drill rod rotates. When used together with the air-drying component 304, the color ring can be dried quickly without affecting the subsequent drill rod maintenance.

[0037] A pushing assembly 9 is fixedly connected to one end of the first working platform 1 for pushing the drill rod on the first roller and the second roller onto the conveying roller group 7 , and the conveying roller group 7 transports the drill rod to the second working platform 2 .

[0038] The steel grade printing assembly 4 includes: a second bracket 401, the second bracket 401 is fixedly connected to the bottom of the first workbench 1, the top of the second bracket 401 is fixedly connected to a third inverted U-shaped frame 402, the third inverted U-shaped frame 402 is rotatably connected to the first rotating shaft 101 or the second rotating shaft 103, the top of the second bracket 401 is fixedly connected to a telescopic frame 403, the telescopic frame 403 can be a telescopic cylinder, the top telescopic end of the telescopic frame 403 is fixedly connected to a cantilever 404, and the cantilever 404 is fixedly connected to a steel grade spray gun 405.

[0039] By relying on the fixed connection between the second bracket 401 and the bottom of the first workbench 1 and the suspension of the third inverted U-shaped frame 402, the second bracket 401 can be installed very stably, and the telescopic frame 403 can be telescoped up and down to drive the cantilever 404 and the steel grade spray gun 405 to approach or move away from the drill rod. When spraying is required, control them to approach the drill rod 10 for spraying, and after the spraying is completed, drive the cantilever 404 and the steel grade spray gun 405 away from the drill rod to avoid interfering with the movement of the drill rod.

[0040] In one embodiment, it also includes: a steel grade imprinting component 5, which is slidably connected to the ground and is used to print the steel grade of the drill rod 10 that has been processed and qualified by the male head repair 6 on the second workbench 2.

[0041] After the drill rod is processed and qualified by the male head repair 6, the entire inspection of the drill rod is completed, and the steel number is sprayed on the drill rod to complete the final marking.
