Technical Field
[0001] This utility model relates to the technical field of drill pipe painting equipment components, and in particular to an automatic drill pipe painting auxiliary component. Background Technology
[0002] When coating drill pipes, different requirements often necessitate multiple steps and processes. Some drill pipes also require different colors.

When used in conjunction with a slide rail assembly, it allows for flexible adjustment of the distance between the component and the drill rod, thus meeting the processing requirements of different drill rod products during painting. It also assists in securing the brush heads for various processes, improving the load-bearing strength of the drill bit and enabling continuous processing of different coatings at the same location. Different paints can be set as needed, accommodating continuous processing of different coatings or colors. Overall, it offers higher processing efficiency, occupies less space at the connection points, ensures better stability between coatings, and guarantees higher painting quality for the drill rods.
[0004] The technical solution of this utility model is as follows:

[0006] Furthermore, the width of the stabilizing safety groove is the same as the width of the coating mating auxiliary groove in the vertical direction.
[0007] Furthermore, the depth of the mounting stabilizing support groove in the vertical direction is less than one-third of the thickness of the main body and the stabilizing seat in the vertical direction.
[0008] Furthermore, the coating mating auxiliary groove is located at the center of the thickness of the main body mating stabilizing seat in the vertical direction.
[0009] The beneficial effects of this utility model are:
[0010] This utility model can be used in conjunction with a slide rail assembly, allowing for flexible adjustment of the distance between the assembly and the drill rod. This enables the assembly to be used with different drill rod products during coating processes. It also provides auxiliary fastening for multiple coating processes, improving the drill bit's load-bearing strength and allowing for continuous processing of different coatings at the same location. Different paints can be selected as needed, accommodating continuous processing of different coatings or colors. Overall processing efficiency is higher, the connection points occupy less space, and the stability between coatings is better, ensuring higher coating quality for the drill rod.

[0019] like Figures 1 to 7As shown, an automatic paint spraying auxiliary component for drill pipes includes a main body with a stabilizing base 1. The main body of the stabilizing base 1 is a cuboid structure. Symmetrical, outward-opening arc-shaped mounting and stabilizing support grooves 2 are located on the upper and lower sides of the left side of the main body with the stabilizing base 1. During installation, these grooves can be engaged with a slide rail structure, allowing for adjustments to the spacing of drill pipes of different specifications, thus meeting the processing needs of various drill pipe products. On the front of the main body with the stabilizing base 1, between the two mounting and stabilizing support grooves 2, are two cylindrical fastening connection holes 3 distributed laterally, for fastening with fastening accessories. The front of the main body with the stabilizing base 1 also features a uniformly distributed, through-type painting auxiliary groove 4, which can engage with different functional brush heads. This position conceals the paint inside, providing better protection during painting and reliably reinforcing the brush head. The coating engagement auxiliary groove 4 has a rectangular cross-section. On each of its left and right sides, there is a V-shaped engagement stabilization and safety groove 5, which allows for a larger internal space, resulting in a larger combined area and better engagement stability when engaging with the brush head. This product can be used with multiple functional brush heads simultaneously. The evenly distributed brush heads enable different coating processes on the drill rod. During processing, the brush rod or this component can be moved sequentially for each coating step, making the overall operation more convenient. It can replace multiple existing coating processes by integrating multiple brush heads into one unit, resulting in higher overall coating efficiency. When in use, it can be used in conjunction with the slide rail assembly, allowing for flexible adjustment of the distance between the assembly and the drill rod. This enables it to meet the processing requirements of different drill rod products during coating operations. It also provides auxiliary fastening for multiple coating processes, improving the drill bit's load-bearing strength and enabling continuous processing of different coatings at the same location. Different paints can be set as needed, accommodating continuous processing of different coatings or colors. Overall, it offers higher processing efficiency, occupies less space at connection points, ensures better stability between coatings, and guarantees higher coating quality for the drill rod.
[0020] Preferably, the width of the stabilizing safety groove 5 is the same as the width of the coating mating auxiliary groove 4 in the vertical direction, which makes the internal reinforcement space larger, allowing for a larger space to fit with the coating installation structure, ensuring better stability of the mating position, and further improving the coating load-bearing capacity during use.
[0021] Preferably, the depth of the mounting stabilizing support groove 2 in the vertical direction is less than one-third of the thickness of the main body and the stabilizing seat 1 in the vertical direction, so that the structural strength between them is better and the structural safety during use is higher.
[0022] Preferably, the coating mating auxiliary groove 4 is located at the center of the thickness of the main body mating stabilizing seat 1 in the vertical direction, so that the mating load-bearing capacity at this position is stronger.
[0023] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
