[0002] When large pipelines are used as medium pipelines, generally an anti-freezing structure is provided on the outer wall of the pipeline, including adding a thermal insulation layer, a tracing tape and an iron sheet shell. This anti-freezing structure is difficult to bear a large gravity, and is prone to deformation when bearing a large weight, affecting the aesthetics and thermal insulation effect. The outer wall of the large pipeline is marked by color rings, that is, color marking is carried out on the outermost layer of the anti-freezing structure.

The painting pipe ring 31 of the painting mechanism 30 is movably connected to the guiding component 20 to paint the pipeline along the guiding component 20, so as to form a color mark with a certain width on the outer wall of the pipeline. The painting pipe ring 31 is sleeved on the pipeline, and the painting pipe ring 31 sprays the outer wall of the pipeline circumferentially along the pipeline through the painting part 311, so as to form an annular color mark on the outer wall of the pipeline. Through the pipeline painting device 100 of the present disclosure, automatic painting of the outer wall of the pipeline can be realized, the painting efficiency of the outer wall of the pipeline can be improved, labor can be saved, and at the same time, the color mark formed by painting is not easy to fall off, and the service life of the color ring is improved.

[0033] In some embodiments of the present disclosure, the fixing component 10 includes: a retaining edge 11 and a binding hoop 12. The retaining edge 11 is an open annular structure. The retaining edge 11 is sleeved on the pipeline, and both ends of the guiding component 20 are respectively connected to the two retaining edges 11. The guiding component 20 is fixed on the outer wall of the pipeline through the two retaining edges 11. The binding hoop 12 is arranged on the retaining edge 11. The binding hoop 12 tightens the retaining edge 11 on the outer wall of the pipeline so that the retaining edge 11 is more firmly connected to the outer wall of the pipeline.

[0034] Specifically, the binding hoop 12 can be arranged at both ends of the opening of the retaining edge 11. By tightening both ends of the opening of the retaining edge 11, the retaining edge 11 is tightened on the outer wall of the pipeline; the binding hoop 12 can also be sleeved on the outside of the retaining edge 11. By tightening the binding hoop 12, the retaining edge 11 is tightened on the outer wall of the pipeline.

[0035] In some embodiments of the present disclosure, the binding hoop 12 is sleeved on at least part of the retaining edge 11. Specifically, the binding hoop 12 can be sleeved on the outer wall of the entire retaining edge 11, or a raised portion (not shown in the figure) having the same shape as and corresponding to the retaining edge 11 is arranged on one side of the retaining edge 11, that is, the raised portion is an open annular structure. The binding hoop 12 is sleeved on the raised portion, and by tightening the raised portion by the binding hoop 12, the purpose of tightening the retaining edge 11 is achieved.

[0036] Specifically, one side of the retaining edge 11 facing another set of fixing components 10 is connected to the guiding component 20. A raised portion is provided on the side of the retaining edge 11 facing away from another set of fixing components 10. The raised portion is an open annular structure. The open raised portion is arranged corresponding to the open retaining edge 11. The binding hoop 12 is sleeved on the raised portion to tighten the retaining edge 11 on the outer wall of the pipeline by tightening the raised portion.

[0037] The binding hoop 12 in this embodiment can be a tightenable clamp, or the binding hoop 12 can also be a tightening strap, etc.

[0038] In some embodiments of the present disclosure, the guiding component 20 includes at least three guiding rods 21. The at least three guiding rods 21 are arranged at intervals along the circumferential direction of the paint spraying pipe ring 31. The paint spraying pipe ring 31 is slidably connected to the at least three guiding rods 21 through the outer side of its circumference, so that the at least three guiding rods 21 provide a guiding effect for the paint spraying pipe ring 31. Both ends of the guiding rod 21 are respectively connected to the two retaining edges 11. The two retaining edges 11 provide a fixed position for the guiding rod 21 to provide a stable guiding effect for the paint spraying conduit.

[0039] In some embodiments of the present disclosure, the number of the guiding rods 21 is three. The three guiding rods 21 are arranged at intervals and evenly distributed along the circumferential direction of the paint spraying pipe ring 31. The guiding effect on the paint spraying pipe ring 31 can be realized through the three guiding rods 21. At the same time, the three guiding rods 21 can also prevent the paint spraying pipe ring 31 from slipping out between the guiding components 20 to provide a stable and reliable guiding effect for the paint spraying pipe ring 31.

[0040] In some embodiments of the present disclosure, the paint spraying portion 311 includes a plurality of paint spraying holes, and the plurality of paint spraying holes are provided on the side of the paint spraying pipe ring 31 facing the pipeline, that is, the plurality of paint spraying holes are provided on the inner ring side of the paint spraying pipe ring 31, so as to ensure that the paint sprayed from the paint spraying holes of the paint spraying pipe ring 31 falls on the outer wall of the pipeline to the greatest extent.

[0041] In other embodiments of the present disclosure, the paint spraying portion 311 may also include an annular paint spraying groove provided on the side of the paint spraying pipe ring 31 facing the pipeline; the paint spraying portion 311 may also include a plurality of arc-shaped paint spraying grooves provided on the side of the paint spraying pipe ring 31 facing the pipeline.

[0042] In some embodiments of the present disclosure, the plurality of paint spraying holes are arranged at intervals along the circumferential direction of the paint spraying pipe ring 31. By means of the plurality of paint spraying holes that are spaced and evenly distributed along the circumferential direction of the paint spraying pipe ring 31, the uniformity of the paint sprayed on the outer wall of the pipeline can be improved.

[0043] In some embodiments of the present disclosure, the included angle between the normal direction of the paint spraying hole and the radial direction of the paint spraying pipe ring 31 ranges from 25° to 75°. When the paint is sprayed onto the outer wall of the pipeline through the paint spraying holes of the paint spraying pipe ring 31, the paint will give a reaction force to the paint spraying pipe ring 31. Within the above-mentioned included angle range, after the paint is sprayed onto the outer wall of the pipeline through the paint spraying holes of the paint spraying pipe ring 31, the reaction force of the paint on the paint spraying pipe ring 31 enables the paint spraying pipe ring 31 to move along the guide rod 21, that is, the paint spraying pipe ring 31 in this embodiment can move along the guide rod 21 without being driven by an external driving device. Under the reaction of the paint spraying, the paint spraying pipe ring 31 moves along the guide rod 21 and sprays paint on the outer wall of the pipeline, so as to form a ring-shaped color mark with a certain width on the outer wall of the pipeline.

[0044] In some embodiments of the present disclosure, the included angle between the normal direction of the paint spraying hole and the radial direction of the paint spraying pipe ring 31 is 30°. When the included angle between the normal direction of the paint spraying hole and the radial direction of the paint spraying pipe ring 31 is 30°, the moving speed of the paint spraying pipe ring 31 is moderate, and the paint sprayed by the paint spraying pipe ring 31 can form a color mark with a certain thickness on the surface of the pipeline. The color mark with the certain thickness can be clearly displayed and no paint spraying waste will be caused.

[0045] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present disclosure. However, the present disclosure is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present disclosure, and these modifications and improvements are also regarded as the protection scope of the present disclosure.
