Description

Technical Field

[0001] This utility model relates to the field of processing devices, and in particular to a device for anti-corrosion treatment of weld seams in anti-corrosion pipes. Background Technology

[0002] Corrosion-resistant pipes, also known as anti-corrosion steel pipes, are steel pipes that have undergone special anti-corrosion treatment. This treatment aims to effectively prevent or slow down corrosion of the steel pipes during transportation and use due to chemical or electrochemical reactions. Corrosion-resistant pipes possess excellent properties such as resistance to chemical corrosion, cathodic disbondment, and mechanical damage, significantly extending the service life of the steel pipes and reducing operating costs. They are widely used in pipeline engineering fields such as petroleum, chemical, natural gas, heating, sewage treatment, water supply, bridges, and steel structures, and are an indispensable part of modern industrial and infrastructure construction.

[0003] In the prior art, there is a Chinese utility model patent with publication number "CN208960183U" and patent name "Anti-corrosion treatment device for weld seam of small diameter steel pipe". The patent describes technical solutions such as "including atomizing nozzle, paint spray pipe, spray gun, hose, and spray pump, characterized in that: the inlet of the spray gun is connected to the spray pump through the hose, and the outlet of the spray gun is connected to the atomizing nozzle through the paint spray pipe".

[0004] However, this technical solution has obvious limitations in practical applications. When using this device to perform anti-corrosion treatment on the weld seams of the inner wall of the pipeline, the staff needs to hold the spray gun for a long time and accurately locate the weld seam. This not only greatly increases the labor intensity of the staff, but also makes it difficult to ensure the stability and uniformity of the spraying when holding the spray gun for a long time. This can easily lead to poor anti-corrosion treatment effect at the weld seam, affecting the overall quality and service life of the anti-corrosion pipe, thereby reducing the anti-corrosion treatment effect and efficiency of the pipeline weld seam.

[0005] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a device for anti-corrosion treatment of weld seams in anti-corrosion pipes. Utility Model Content

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A corrosion protection device for welded seams of anti-corrosion pipes includes a treatment table. Several arc-shaped support plates are fixedly connected to the top surface of the treatment table. A treatment mechanism is provided on the top surface of the treatment table, and the mechanism includes an external gear ring, a first motor, a first gear, a cylinder, a frame, a rack, a second gear, a second motor, a spray pipe, and a nozzle. The external gear ring is movably connected to the side wall of a support plate on the right side of the top surface of the treatment table via a convex ring on its side wall. The first motor is fixedly connected to the side wall of the top plate of the support plate, and the first gear is fixedly connected to the output end of the first motor and meshes with the external gear ring.

One end of the rotating rod is fixedly connected to the output end of the second motor on the side wall of the frame. The spray pipe is fixedly connected to the bottom surface of the rack, and the nozzle is fixedly connected to one end of the spray pipe.

[0009] Furthermore, the support plate is fixedly installed on the right side of the top surface of the processing table, and an opening is provided on the side wall of the support plate. An annular groove is provided on the right side wall of the support plate, and a top plate is fixedly installed on the top surface of the support plate.

[0010] Furthermore, a convex ring is fixedly installed on the left side wall of the external gear ring, and the convex ring is movably installed in the convex groove. The first motor is fixedly installed on the left side wall of the top plate, and a first gear is fixedly installed on the output end of the first motor. The first gear meshes with the external gear ring.

[0011] Furthermore, a horizontal plate is fixedly installed inside the external toothed ring, and a set of symmetrical guide rods is fixedly installed on the top surface of the horizontal plate. The cylinder is fixedly installed on the bottom surface of the horizontal plate, and a frame is fixedly installed at the output end of the cylinder. T-shaped guide blocks are fixedly installed on both sides of the inner wall of the frame, and rotating holes are also opened on both sides of the inner wall of the frame. Connecting plates are fixedly installed on the top of the two side walls of the frame, and guide holes are opened on the top surface of the connecting plates and are movably installed together with the guide rods through the guide holes.

[0012] Furthermore, T-shaped guide grooves are respectively provided on the two side walls of the rack, and T-shaped guide blocks are movably installed in the T-shaped guide grooves. Rotating rods are fixedly installed at both ends of the second gear, and the rotating rods are movably installed in the rotating holes.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the processing mechanism places the anti-corrosion pipe to be processed onto the arc-shaped support plate on the top surface of the processing table. Then, the output of the second motor is activated, driving the second gear to rotate via a rotating rod. This causes the second gear to mesh and move the rack to the left, allowing the spray nozzle on the bottom of the rack to enter the anti-corrosion pipe. Once the nozzle reaches the weld position, the output of the first motor is activated, driving the first gear to rotate. This causes the first gear to mesh and rotate the outer gear ring, thus adjusting the direction of the nozzle until it faces the weld. Finally, the output of the cylinder is activated, pushing the frame to move along the guide rod via the connecting plate, allowing the nozzle to... Approaching the weld seam, the pump is activated to extract the anti-corrosion coating from the spray gun tank and deliver it through a delivery hose to the spray pipe.

It effectively avoids poor anti-corrosion treatment results caused by unstable manual spraying, improving the overall quality and service life of the anti-corrosion pipe. Furthermore, it provides rapid and precise comprehensive anti-corrosion treatment of the weld seam, greatly increasing the efficiency of pipeline weld anti-corrosion treatment compared to manual operation.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 - Figure 5 As shown, a corrosion protection device for weld seams of anti-corrosion pipes includes a treatment table 1. Several arc-shaped support plates 2 are fixedly connected to the top surface of the treatment table 1. A treatment mechanism 3 is provided on the top surface of the treatment table 1. The treatment mechanism 3 includes an external gear ring 11, a first motor 15, a first gear 16, a cylinder 17, a frame 18, a rack 23, a second gear 25, a second motor 27, a spray pipe 28, and a spray nozzle 29. The external gear ring 11 is movably connected to the side wall of the support plate 4 on the right side of the top surface of the treatment table 1 via a protruding ring 12 on its side wall. The first motor 15 is fixedly connected to the side wall of the top plate 7 on the top surface of the support plate 4. The first gear 16... The first motor 15 is fixedly connected to the output end and meshes with the outer gear ring 11. The cylinder 17 is fixedly connected to the bottom surface of the inner horizontal plate 13 of the outer gear ring 11, and the frame 18 is fixedly connected to the output end of the cylinder 17. The rack 23 is movably connected to the frame 18 through the T-shaped guide grooves 24 on both sides, and the second gear 25 is movably connected to the frame 18 through the rotating rods 26 at both ends and meshes with the rack 23. One end of the rotating rod 26 is fixedly connected to the output end of the second motor 27 on the side wall of the frame 18. The spray pipe 28 is fixedly connected to the bottom surface of the rack 23, and the nozzle 29 is fixedly connected to one end of the spray pipe 28.

[0024] like Figure 2As shown, the support plate 4 is fixedly installed on the right side of the top surface of the processing table 1, and the side wall of the support plate 4 is provided with an opening 5. The right side wall of the support plate 4 is provided with an annular groove 6. The cooperation between the annular groove 6 and the protruding ring 12 allows the external toothed ring 11 to rotate stably and flexibly around the support plate 4, providing a basis for the subsequent nozzle 29 to make a circular motion around the anti-corrosion pipe. The top surface of the support plate 4 is fixedly installed with a top plate 7, which provides a stable support position for the installation of the first motor 15.

[0025] like Figure 3 and Figure 4 As shown, a convex ring 12 is fixedly installed on the left side wall of the external gear ring 11, and the convex ring 12 is movably installed in the convex groove 6. The first motor 15 is fixedly installed on the left side wall of the top plate 7, and a first gear 16 is fixedly installed on the output end of the first motor 15. The first gear 16 and the external gear ring 11 mesh together. When the first motor 15 runs, the first gear 16 rotates and drives the external gear ring 11 to rotate around the support plate 4, realizing the automatic rotation of the external gear ring 11. This drives the nozzle 29 installed on the external gear ring 11 to make a circular motion around the anti-corrosion pipe, so that the nozzle 29 can spray the weld seam in the entire circumferential direction of the inner wall of the anti-corrosion pipe, improving the comprehensiveness and efficiency of the spraying, reducing the workload of manual operation, and the spraying direction of the nozzle 29 can be quickly adjusted according to the weld seam position.

[0026] like Figure 4 and Figure 5 As shown, a horizontal plate 13 is fixedly installed inside the external toothed ring 11, and a set of symmetrical guide rods 14 are fixedly installed on the top surface of the horizontal plate 13. A cylinder 17 is fixedly installed on the bottom surface of the horizontal plate 13, and a frame 18 is fixedly installed at the output end of the cylinder 17. T-shaped guide blocks 19 are fixedly installed on both sides of the inner wall of the frame 18, and rotating holes 20 are opened on both sides of the inner wall of the frame 18. Connecting plates 21 are fixedly installed on the top of the two side walls of the frame 18, and guide holes 22 are opened on the top surface of the connecting plates 21. They are movably installed together with the guide rods 14 through the guide holes 22. Through the cooperation of the cylinder 17 and the guide rods 14, the height of the frame 18 and the nozzle 29 installed on the frame 18 can be precisely adjusted so that it can accurately approach and align with the anti-corrosion pipe weld at different height positions, thereby improving the accuracy and adaptability of the spraying and ensuring the quality of anti-corrosion treatment at the weld.

[0027] like Figure 5As shown, T-shaped guide grooves 24 are respectively opened on both sides of the rack 23, and T-shaped guide blocks 19 are movably installed in the T-shaped guide grooves 24. Rotating rods 26 are fixedly installed at both ends of the second gear 25, and the rotating rods 26 are movably installed in the rotating holes 20. The second motor 27 is fixedly installed on the side wall of the frame 18, and the output end of the second motor 27 is fixedly installed with one end of the rotating rod 26. When the second motor 27 is running, it drives the rotating rod 26 and the second gear 25 to rotate, thereby driving the rack 23 to make linear motion in the frame 18. This not only allows the nozzle 29 to move inside the anti-corrosion pipe to adapt to the processing requirements of anti-corrosion pipes of different lengths, but also allows the nozzle 29 to spray along the weld direction of the anti-corrosion pipe, further improving the accuracy and uniformity of the spraying, ensuring that every part of the weld can be well protected against corrosion, and reducing the error of manual operation.

[0028] like Figure 3 and Figure 5 As shown, the spray pipe 28 is fixedly installed on the bottom surface of the rack 23, and the right end of the spray pipe 28 is fixedly installed with a nozzle 29. The top surface of the treatment table 1 is also fixedly installed with a paint tank 8 and a pump body 9. The input end of the pump body 9 is fixedly installed together with the paint tank 8 and connected. The output end of the pump body 9 is fixedly installed with a delivery hose 10 between it and the right end of the spray pipe 28. When the pump body 9 is working, it delivers the anti-corrosion paint in the paint tank 8 to the spray pipe 28 through the delivery hose 10, and then sprays it out from the nozzle 29. This ensures the smooth progress of the spraying process and ensures the quality and efficiency of the anti-corrosion treatment. The delivery hose 10 has a certain degree of flexibility and does not affect the movement of the nozzle 29.

[0029] The specific anti-corrosion treatment operation of the weld seam on the inner wall of the anti-corrosion pipe by the treatment mechanism 3 is as follows:

[0030] The anti-corrosion pipe to be treated is placed on the arc-shaped support plate 2 on the top surface of the treatment table 1. The arc-shaped support plate 2 supports the anti-corrosion pipe. The second motor 27 is turned on to drive the output end to rotate the rotating rod 26 within the rotating hole 20. The rotating rod 26 drives the second gear 25 to rotate. During the rotation and meshing process, the second gear 25 drives the rack 23 to move to the left. The rack 23 moves along the T-shaped guide block 19 through the T-shaped guide grooves 24 on both sides, so that the nozzle 29 passes through the opening 5 on the side wall of the support plate 4 and enters the anti-corrosion pipe. Inside, after the nozzle 29 moves to the same horizontal position as the weld seam inside the anti-corrosion pipe, the first motor 15 installed on the side wall of the top plate 7 is turned on. The first motor 15 will drive the first gear 16 to rotate. The first gear 16 will drive the outer gear ring 11 to rotate under the rotational meshing action. The convex ring 12 on the left side wall of the outer gear ring 11 will rotate in the convex groove 6 opened on the right side wall of the support plate 4, thereby driving the nozzle 29 to rotate until the nozzle 29 faces the weld seam position. Then, the cylinder 17 installed on the bottom surface of the horizontal plate 13 is turned on. 17. The drive output end pushes the frame 18, causing the frame 18 to move along the guide rod 14 through the guide holes 22 on the top surface of the connecting plates 21 on both sides until the nozzle 29 approaches the weld. Then, the pump body 9 is turned on to extract the anti-corrosion coating from the paint tank 8 and deliver it through the delivery hose 10 to the spray pipe 28 installed on the bottom surface of the rack 23. Finally, the coating is sprayed onto the weld through the nozzle 29 to perform anti-corrosion treatment on the weld. At the same time, during the process of spraying the weld, the linear movement of the rack 23 and the rotation of the outer gear ring 11 can be used to spray the coating. The nozzle 29 sprays the entire weld seam along the weld seam, thus enabling automatic treatment of the anti-corrosion pipe weld seam. This eliminates the need for manual operation of the spray gun for extended periods, greatly reducing the labor intensity of workers and ensuring the stability and uniformity of the spraying. It effectively avoids the problem of poor anti-corrosion treatment caused by unstable manual spray gun operation, improving the overall quality and service life of the anti-corrosion pipe. At the same time, it can quickly and accurately perform comprehensive anti-corrosion treatment on the weld seam, greatly improving the efficiency of anti-corrosion treatment of pipeline weld seams compared to manual operation.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
