Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe processing and production, in particular to a spraying device for anti-corrosion materials on the surface of an oil pipe. Background Technique

[0002] In the petrochemical field, the quality of pipeline anti-corrosion determines the service life of the pipeline, especially for pipelines transporting oil and gas. Since most of them are in complex working environments and the transported media are mostly corrosive, both the inner and outer walls of the pipeline may be corroded. Once the pipeline is corroded and perforated, it will cause leakage losses of media such as oil and gas transported, not only interrupting the transportation, but also polluting the environment. More seriously, it may even cause a fire and pose a hazard.

[0003] For example, the Chinese patent with the publication number CN219092478U discloses an oil pipe coating spraying device, including a base, a paint bucket, a pump body and a feed pipe. An arc-shaped groove is opened on the upper end surface of the base, and a driving wheel is fixedly connected to the inner wall of the arc-shaped groove. A motor is fixedly connected to the upper end surface of the base, and the end of the output shaft of the motor is fixedly connected to a driving roller. The other end of the driving roller is rotatably connected to the inner wall of the arc-shaped groove. A chute is opened on the upper end surface of the base, and a slider is slidably connected to the inner side of the chute. A connecting column is fixedly connected to the upper end of the slider, a connecting block is fixedly connected to the rear end of the connecting column, and a sliding sleeve is fixedly connected to the other end of the connecting block. A spraying plate is arranged at the rear side of the connecting column. Connecting pieces are fixedly connected to the left and right sides of the front end surface of the front spraying plate. A sliding rod is slidably connected to the inner side of the sliding sleeve. By setting structures such as the connecting column, the spraying plate, and the spring, the coating spraying device can simultaneously spray the inner and outer walls of the oil pipe, improving the practicability of the device.

[0004] This patent inserts the spraying plates on both sides into the oil pipe so that the spraying plates are stuck on both sides of the oil pipe wall, and sprays the inner and outer walls of the oil pipe simultaneously, realizing the ability of the coating spraying device to spray the inner and outer walls of the oil pipe simultaneously. During the spraying process, the splashing of the paint will affect the health of the surrounding operators. Content of the Utility Model

[0027] In order to make the content of the utility model be more clearly understood, the following further detailed description of the utility model is given according to specific embodiments and in conjunction with the accompanying drawings.

[0028] AsFigures 1-5 As shown, in this embodiment, a spraying device for the anti-corrosion material on the surface of the oil pipe is provided, including a workbench 1. A spraying mechanism 2 and a clamping mechanism 3 are arranged on the workbench 1. The spraying mechanism 2 is used to evenly spray the anti-corrosion material on the inner and outer surfaces of the oil pipe, and the clamping mechanism 3 is used to fix the oil pipe during the spraying process. The spraying mechanism 2 and the clamping mechanism 3 are respectively located on both sides of the workbench 1, and the clamping mechanism 3 can slide relative to the spraying mechanism 2.

[0029] As Figures 1-5 shown, in this embodiment, the spraying mechanism 2 includes a spraying cylinder 21, an outer spray gun 22 and an inner spray gun 23 arranged in the spraying cylinder 21. The outer spray gun 22 and the inner spray gun 23 can slide relative to the inner wall of the spraying cylinder 21. During spraying, the oil pipe extends into the spraying cylinder 21, so that the spraying cylinder 21 can wrap the oil pipe. The outer spray gun 22 is located between the inner wall of the spraying cylinder 21 and the outer wall of the oil pipe, and the inner spray gun 23 is located inside the oil pipe, so that the outer spray gun 22 and the inner spray gun 23 can spray the outer wall and the inner wall of the oil pipe simultaneously. Specifically, a positioning plate 24 is fixedly arranged on the workbench 1, and one side of the spraying cylinder 21 far from the clamping mechanism 3 is fixedly installed on the positioning plate 24. Sliding rods 25 are fixedly connected to both the outer spray gun 22 and the inner spray gun 23, and the other ends of the sliding rods 25 are slidably arranged on the positioning plate 24, so that the outer spray gun 22 and the inner spray gun 23 can slide relative to the spraying cylinder 21.

[0030] As Figures 1-5 shown, in this embodiment, a chute 241 is formed on the positioning plate 24, and the sliding rod 25 is slidably arranged in the chute 241. A driving cylinder 26 is fixedly arranged on one side of the positioning plate 24 far from the spraying cylinder 21. One end of the sliding rod 25 far from the outer spray gun 22 and the inner spray gun 23 extends outside the positioning plate 24 through the chute 241, and the output end of the driving cylinder 26 is fixedly connected to the sliding rod 25. By driving the sliding rod 25 to move through the driving cylinder 26, the outer spray gun 22 and the inner spray gun 23 can slide relative to the side wall of the spraying cylinder 21, so that the relative positions of the outer spray gun 22 and the inner spray gun 23 can be adjusted according to the diameter and wall thickness of the oil pipe to be sprayed, thereby ensuring the spraying effect.

[0031] As Figures 1-5As shown, in this embodiment, in order to ensure the stability of the sliding rod 25 during sliding, a sliding member 251 is fixedly sleeved on the side of the sliding rod 25 away from the outer spray gun 22 and the inner spray gun 23. The sliding member 251 is slidably arranged in the chute 241. Specifically, the sliding member 251 includes a sliding block 2511 sleeved on the sliding rod 25. The outer diameter of the sliding block 2511 corresponds to that of the chute 241. A through hole 2512 corresponding to the sliding rod 25 for the sliding rod 25 to pass through is formed in the sliding block 2511. Limiting plates 2513 are fixedly arranged at both ends of the sliding block 2511. The limiting plates 2513 are in contact with the end face of the positioning plate 24 to ensure that the sliding block 2511 will not slide out of the chute 241, and further ensure the stability of the sliding rod 25 during sliding.

[0032] As Figures 1-5 shown, in this embodiment, spray pipes are connected to both the outer spray gun 22 and the inner spray gun 23, and the other ends of the spray pipes are communicated with the paint tank.

[0033] As Figures 1-5 shown, in this embodiment, the clamping mechanism 3 includes a clamping plate 31 slidably arranged on the workbench 1. A rotatable clamping seat 32 is arranged on the side of the clamping plate 31 close to the spraying mechanism 2. An inner claw 33 is arranged on the side of the clamping seat 32 close to the spraying mechanism 2. One end of the oil pipe abuts against the end face of the clamping seat 32 on the side away from the clamping plate 31, and the inner claw 33 abuts against the inner wall of the oil pipe, so that the oil pipe can be fixedly installed on the clamping seat 32. In this embodiment, the inner claw 33 is connected to the clamping seat 32 in the form of a three-jaw chuck in the prior art.

[0034] As Figures 1-5As shown in the figure, in this embodiment, a slide rail 11 is provided on the workbench 1, and a sliding groove 311 corresponding to the slide rail 11 is formed on the clamping plate 31, so that the clamping plate 31 can slide relative to the spraying mechanism 2 on the workbench 1. A driving component 12 for driving the clamping plate 31 to slide is provided on the workbench 1. The driving component 12 includes a transmission motor 121 and a transmission lead screw 122. The transmission motor 121 is fixedly installed on the workbench 1 and is used to drive the transmission lead screw 122 to rotate. The transmission lead screw 122 is arranged parallel to the slide rail 11 and is located on one side of the slide rail 11. One end of the transmission lead screw 122 is fixedly connected to the transmission motor 121, and the other end of the transmission lead screw 122 passes through the clamping plate 31 and is rotatably connected to the workbench 1, and the transmission lead screw 122 is threadedly connected to the clamping plate 31. When the transmission motor 121 drives the transmission lead screw 122 to rotate, the transmission lead screw 122 can drive the clamping plate 31 to move along the slide rail 11 on the workbench 1. In other embodiments not shown, the driving component 12 can also be a structure well-known to those skilled in the art such as a hydraulic cylinder, which will not be elaborated in this embodiment. The driving component 12 drives the clamping plate 31 to move, so that the oil pipe can extend into the spraying cylinder 21 for spraying.

[0035] As Figures 1-5 shown, in this embodiment, in order to ensure the stability of the clamping plate 31 during sliding, there are two slide rails 11, and the transmission lead screw 122 is located between the two slide rails 11. In other embodiments not shown, the number of slide rails 11 is not limited.

[0036] As Figures 1-5 shown, in this embodiment, the clamping seat 32 is coaxial with the spraying cylinder 21 to ensure that the installed oil pipe can extend into the spraying cylinder 21 and the oil pipe will not collide with the spraying cylinder 21.

[0037] As Figures 1-5 shown, in this embodiment, a driving motor 34 for driving the clamping seat 32 to rotate is further provided on the clamping plate 31. The driving motor 34 drives the clamping seat 32 to rotate, thereby driving the oil pipe fixed on the clamping seat 32 to rotate, and further spraying all circumferential parts of the oil pipe.

[0038] As Figures 1-5 shown, in this embodiment, the inner spray gun 23 and the outer spray gun 22 spray the inner side wall and the outer side wall of the oil pipe respectively. The distances from the inner spray gun 23 and the outer spray gun 22 to the end face of the spraying cylinder 21 close to the clamping plate 31 are the same as the distance from the side of the inner claw 33 away from the clamping plate 31 to the clamping plate 31. The driving component 12 drives the clamping plate 31 to move until the clamping plate 31 abuts against the end face of the spraying cylinder 21. At this time, the end of the oil pipe is just located between the inner spray gun 23 and the outer spray gun 22, thereby ensuring that the oil pipe can be sprayed with the largest area.

[0039] The working process and principle of the present utility model are as follows: Before spraying, one end of the oil pipe is abutted against the end face of the clamping seat 32 on the side far from the clamping plate 31, and the inner claw 33 is abutted against the inner wall of the oil pipe, so that the oil pipe can be fixedly installed on the clamping seat 32; The driving motor 121 drives the driving lead screw 122 to rotate, and the driving lead screw 122 drives the clamping plate 31 to move along the slide rail 11 on the workbench 1, so that the oil pipe extends into the spraying cylinder 21 until the clamping plate 31 abuts against the end face of the spraying cylinder 21. At this time, the end of the oil pipe is just located between the inner spray gun 23 and the outer spray gun 22; The driving cylinder 26 drives the sliding rod 25 to move, so that the outer spray gun 22 and the inner spray gun 23 slide relative to the side wall of the spraying cylinder 21 to adjust the relative positions of the outer spray gun 22 and the inner spray gun 23 according to the diameter and wall thickness of the oil pipe to be sprayed, so as to ensure the spraying effect; During spraying, the driving motor 34 drives the clamping seat to rotate, thereby driving the oil pipe fixed on the clamping seat 32 to rotate, so as to spray all parts of the circumference of the oil pipe. At the same time, the driving motor 121 drives the driving lead screw 122 to rotate in the reverse direction, so that the clamping plate 31 gradually moves away from the spraying cylinder 21, thereby realizing the complete spraying of the oil pipe; The spraying process is carried out in the spraying cylinder 21, which avoids the paint splashing being inhaled by the surrounding staff and affecting their health. During spraying, the inner and outer surfaces of the oil pipe can be sprayed synchronously, improving the work efficiency. At the same time, it can be applied to oil pipes with different diameters and wall thicknesses, improving the application range of the device.

[0040] In the specific embodiments described above, the technical problems solved, technical solutions and beneficial effects of the present utility model are further described in detail. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
