Description

Technical Field

[0001] The present invention relates to the technical field related to ductile iron pipe spraying, and in particular to a ductile iron pipe spraying device. Background Art

[0002] Ductile iron pipes are generally made of centrifugal casting. After the ductile iron pipes are formed, they need to be surface treated by spraying an anti-corrosion layer according to different usage requirements and technical standards, such as spraying zinc or spraying an organic coating or an organic-inorganic composite coating. New pipes generally need surface spraying on both the inner and outer walls. For example, for cast iron pipes buried underground, working in general soil environments, only asphalt coating the outer wall can meet the anti-corrosion requirements. However, for highly corrosive soils, such as swamp soils, muddy soils, sulfate-containing soils, garbage soils and soils contaminated by drainage, the anti-corrosion effect of only asphalt coating is difficult to be satisfactory. The French Musong Bridge Company has been conducting pipe simulation comparison experiments since 1949. The results show that the best anti-corrosion effect is achieved by retaining the oxide scale after annealing the pipe, and then spraying zinc and then coating the composite coating with asphalt.

[0003] For example, Chinese invention patent CN116174277B proposes a surface spraying process for ductile iron pipes. The spraying process uses new tooling and improved spraying equipment that can stably clamp, position, and lift the ductile iron pipes and rotate them. The loading and unloading operations are no longer complicated, and the spraying efficiency is also improved.

[0004] In the prior art, fixed-angle spraying is used, but a fixed-angle spray gun cannot cover complex curved surfaces and easily misses areas, resulting in poor spraying effects. Summary of the Invention

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0038] In view of the fact that in the current existing technology, fixed-angle spraying is used, the fixed-angle spray gun cannot cover complex curved surfaces and is prone to missing areas, resulting in poor spraying effects.

[0039] like Figure 1-4 As shown, an embodiment of the present invention provides a ductile iron pipe spraying device, comprising a base 10; a placement platform 20 is installed on the top of the base 10;

[0040] When spraying, the ductile iron pipe is placed on the placement table 20 by a hoisting device;

[0041] The top of the base 10 is fixedly connected to a fixed column 30; the top of the base 10 is slidably connected to a movable column 40, which includes a column 41 slidably connected to the top of the base 10; a limiting slide rail 42 is symmetrically arranged on the top of the base 10 and slidably connected to the bottom of the column 41; a movable cylinder 43 is fixedly connected to one side of the base 10, and the telescopic end is connected to the outer wall of the column 41;

[0042] The fixed column 30 is fixed to the base 10, and the movable column 40 is slidably arranged on the base 10 by the movable cylinder 43 and the limit slide rail 42. When spraying, the movable column 40 moves inward, so that the movable column 40 and the cast iron pipe clamping assembly 50 in the fixed column 30 cooperate with each other to clamp the two ends of the pipe body;

[0043] A cast iron pipe clamping assembly 50 is provided inside both the fixed column 30 and the movable column 40. The cast iron pipe clamping assembly 50 includes a lifting cylinder 51, which is disposed inside the fixed column 30 or the movable column 40; a lifting plate 52, which is fixedly connected to the telescopic end of the lifting cylinder 51; a clamping plate 53, which is fixedly connected to the top of the lifting plate 52; an inner wall support pipe plug 54, which is rotatably connected to one side of the clamping plate 53; and a rotating motor 55, which is mounted on the other side of the clamping plate 53 and has an output shaft connected to one end of the inner wall support pipe plug 54.

[0044] During clamping, the wall support pipe plug 54 clamps the inner wall of one end of the pipe body. After clamping is completed, the lifting cylinder 51 is started to drive the clamping plate 53 on the top of the lifting plate 52 to rise, so that the wall support pipe plug 54 on the clamping plate 53 drives the pipe body to rise. During spraying, the rotating motor 55 is started to drive the rotating motor 55 to rotate, so that the inner wall support pipe plug 54 drives the pipe body to rotate, and all-round spraying is performed.

[0045] A transverse movement assembly 60 is provided on the top of the base 10. The transverse movement assembly 60 includes a support column 61 fixedly connected to the top of the base 10; a transverse slide 62 is provided on the top of the support column 61; a swing spray assembly 70 is provided at the movable end of the transverse movement assembly 60, and the swing spray assembly 70 includes a moving slide 71 slidably connected to the outer side wall of the transverse movement assembly 60; a swing support frame 72 fixedly connected to the top of the moving slide 71; a spray support plate 73 rotatably connected to the inner side wall of the swing support frame 72; a swing motor 74 is installed on one side of the swing support frame 72; and a spray gun 75 is provided on the outer side wall of the spray support plate 73.

[0046] The transverse slide 62 is a linear motor, model LMG15-200. When spraying, the transverse component 60 drives the moving slide 71 to move back and forth laterally, so that the moving slide 71 drives the swing support frame 72 to move laterally, so that the spray gun 75 on the swing support frame 72 sprays the pipe body in all directions. During the spraying process, by starting the swing motor 74, the swing motor 74 drives the spray support plate 73 to rotate, so that the spray support plate 73 drives the spray gun 75 installed on the outer wall to swing, and swing spraying is performed to improve the spraying effect.

[0047] Furthermore, there are two moving cylinders 43 , and the two moving cylinders 43 improve the stability of the pushing.

[0048] Furthermore, there are two lifting cylinders 51 , and the two lifting cylinders 51 improve the stability of the pushing.

[0049] Furthermore, a jet assembly 80 is provided on one side of the swing support frame 72. The jet assembly 80 includes a connecting plate 81; a transmission rod 82 fixedly connected to one side of the connecting plate 81, one end of which is connected to the rotating shaft of the spray support plate 73; a jet support plate 83 fixedly connected to the other side of the connecting plate 81; and a jet gun 84 mounted on the outer wall of the jet support plate 83.

[0050] In this embodiment, by setting up a jet assembly 80, impurities on the surface of the pipe are blown away before spraying to improve the adhesion of the coating. One end of the jet gun 84 is connected to the high-pressure air source. During the swing spraying process, the transmission rod 82 drives the jet support plate 83 on one side of the connecting plate 81 to swing, so that the jet gun 84 on the jet support plate 83 follows the swing, so that the jet gun 84 blows the outer wall of the pipe body.
