[0002] Pipelines are a common type of infrastructure, typically hollow cylindrical structures. Painting the surface of pipelines is an important means of corrosion protection. A good paint coating can act as a barrier to inhibit the intrusion of corrosive media, thus requiring the use of painting equipment.

[0004] In the above case, the two ends of the pipe are placed in the end holders on both sides for fixation, and then sprayed with a spraying device. However, because the end holder is a fixed structure, it can only fix pipes of one diameter, which reduces the applicability of the device. In addition, the holder will block the two ends of the pipe, making it impossible to spray all parts of the outside of the pipe.

[0005] Therefore, this utility model provides an automatic painting device for pipeline spraying to meet the requirements. Utility Model Content

[0011] In a preferred embodiment, the spraying assembly includes a spraying frame slidably connected to the inside of the spraying base, spraying strips fixedly connected to the inside of the spraying frame, a liquid supply pump fixedly connected to the top of the spraying base, a feed pipe fixedly connected to the output end of the pump, and the other end of the pump fixedly connected to two spraying strips.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figures 1-4 This utility model provides an automatic pipe spraying and painting device, including a base plate 1. A fixed seat 2 is fixedly connected to one side of the top of the base plate 1. A first lead screw 3 is rotatably connected to the side of the top of the base plate 1 away from the fixed seat 2. A sliding seat 4 is threadedly connected to the outer side of the first lead screw 3. Connecting seats 5 are fixedly connected to adjacent sides of the fixed seat 2 and the sliding seat 4. A fixed plate 6 is fixedly connected to the other side of the connecting seat 5. Several sliding grooves 7 are formed on the inner side of the fixed plate 6. A clamping assembly is slidably connected to the inner side of the sliding grooves 7 for fixing the pipe. A second lead screw 10 is rotatably connected to the center of the inner side of the fixed plate 6. A driving assembly is threadedly connected to the outer side of the second lead screw 10. The components include a slider 8 slidably connected to the inner side of the slide groove 7, a support plate 9 fixedly connected to the side of the slider 8 away from the connecting seat 5, and four support plates 9 on the outer side of the same fixed plate 6. The support plates 9 are distributed in a ring around the outer side of the second lead screw 10. The drive assembly includes an inner threaded sleeve 11 threadedly connected to the outer side of the second lead screw 10. A transmission rod 12 is rotatably connected to both ends of the inner threaded sleeve 11. The other end of the transmission rod 12 is rotatably connected to the support plate 9 on the same side. A first motor is fixedly connected to the inner side of the connecting seat 5. Its output end is fixedly connected to the second lead screw 10. The bottom of the shift seat 4 is slidably connected to the top of the base plate 1. A throttle is fixedly connected to the end of the first lead screw 3 away from the fixed seat 2.

[0022] Place one end of the pipe to be sprayed onto the outside of the support plate 9 next to the fixed seat 2. Manually rotate the first screw 3 to move the shift seat 4 along the axial direction of the first screw 3, so that the support plate 9 next to the shift seat 4 moves into the pipe. Start the first motors on both sides to drive the corresponding second screw 10 to rotate. The inner thread sleeve 11 moves axially under the action of the thread of the second screw 10, and pushes the support plate 9 to move outward through the transmission rod 12. The slider 8 slides in the slide groove 7 to limit the movement and hold the two ends of the pipe from the inside.

[0023] The device can precisely support the inner sides of both ends of the pipe through the clamping components on both sides. This not only provides a stable way to fix the pipe, but also avoids the obstruction problems that may be caused by traditional clamping methods. Since the support plate 9 is located inside the pipe, it will not obstruct the outer surface of the pipe. Therefore, the device can spray all parts of the outer side of the pipe without any obstruction. This greatly improves the practicality of the device, enabling it to complete the spraying task of the outer surface of the pipe efficiently and with high quality, and meet the spraying needs under various complex working conditions.

[0024] Please see Figures 1-4 The drive assembly is rotatably connected to several clamping assemblies on the outside. A threaded post 13 is rotatably connected to the top of the base plate 1. A spraying seat 14 is threadedly connected to the outside of the threaded post 13. Spraying assemblies are slidably connected to both ends of the inner side of the spraying seat 14. The spraying assembly includes a spraying frame 15 slidably connected to the inner side of the spraying seat 14. Spraying strips 16 are fixedly connected to the inner side of the spraying frame 15. A liquid supply pump 18 is fixedly connected to the top of the spraying seat 14. A feed pipe 17 is fixedly connected to its output end. Its other end is fixedly connected to two spraying strips 16. A bidirectional screw is rotatably connected to the inner side of the spraying seat 14. Two spraying assemblies are threadedly connected to both ends of the outer side of the bidirectional screw. A second motor is fixedly connected to the top of the base plate 1. Its output end is fixedly connected to the threaded post 13. A bottom rod is fixedly connected to the top of the base plate 1. The bottom end of the spraying seat 14 is slidably connected to the outside of the bottom rod.

[0025] The drive motor inside the spraying base 14 drives the bidirectional screw to rotate, causing the two spraying frames 15 to move closer to the pipeline inside the spraying base 14. The liquid supply pump 18 delivers the paint to the spraying strip 16 through the feed pipe 17. The spraying strip 16 is installed inside the spraying frame 15. The paint is evenly sprayed onto the pipeline surface through the spraying strip 16. The second motor starts and drives the threaded column 13 to rotate, causing the spraying base 14 to move the spraying frame 15 under the limit of the bottom rod, so as to evenly spray the outside of the pipeline. In the above scheme, it should be noted that: since the spraying strip 16 is arc-shaped and the spraying head is evenly distributed on the spraying strip 16, and since two spraying strips 16 are combined together in a ring shape and the spraying head is evenly distributed, when the spraying head is spraying paint, its spraying range can cover the gap between the spraying head, so that the surface of the pipe can be fully adhered to the paint.

[0026] When the second lead screw 10 rotates, the inner threaded sleeve 11 connected to its outer thread will be displaced axially. The two ends of the inner threaded sleeve 11 are connected to the support plate 9 through the transmission rod 12. These transmission rods 12 cleverly convert the displacement of the inner threaded sleeve 11 into the radial movement of the support plate 9. As the inner threaded sleeve 11 moves, the transmission rods 12 will push all the support plates 9 to expand outward or contract inward synchronously, thereby realizing the clamping or loosening operation on the inside of the pipe. The slider 8 is fixed on the support plate 9 and slides in the groove 7 on the inner side of the fixed plate 6. The shape and position of the groove 7 determine the expansion or contraction of the support plate 9. The direction of movement during the contraction process ensures that the support plate 9 always moves along a predetermined straight trajectory, avoiding possible skewness or instability. In this way, the device can adapt to pipes of different diameters. Whether it is a small-diameter thin pipe or a large-diameter thick pipe, precise clamping can be achieved by adjusting the expansion degree of the support plate 9. This not only significantly improves the applicability of the device, enabling it to be widely used in various pipe spraying scenarios, but also greatly enhances the stability and reliability of the device, ensuring that the pipe remains stable and fixed during the spraying process, thereby improving the spraying quality and efficiency.

[0027] The working principle and usage process of this utility model are as follows: One end of the pipe to be sprayed is fitted onto the outside of the support plate 9 next to the fixed seat 2. The first screw 3 is manually rotated, causing the moving seat 4 to move axially along the first screw 3, so that the support plate 9 next to the moving seat 4 moves into the pipe. The first motors on both sides are started, driving the corresponding second screw 10 to rotate. The inner threaded sleeve 11 moves axially under the action of the thread of the second screw 10, pushing the support plate 9 to move outward through the transmission rod 12. The slider 8 slides in the slide groove 7 for limiting, from the inside... The spraying base 14 holds the two ends of the pipe, and the drive motor inside the spraying base 14 drives the bidirectional screw to rotate, so that the two spraying frames 15 move closer to the pipe inside the spraying base 14. The liquid supply pump 18 delivers the paint to the spraying strip 16 through the feed pipe 17. The spraying strip 16 is installed inside the spraying frame 15. The paint is evenly sprayed onto the surface of the pipe through the spraying strip 16. The second motor starts and drives the threaded column 13 to rotate, so that the spraying base 14 moves the spraying frame 15 under the limit of the bottom rod, and evenly sprays the outside of the pipe.
