[0001] The present invention relates to the technical field of pipe pile spraying devices, and in particular to a pipe pile spraying device and method for a photovoltaic support. Background Art
[0002] The pipe pile spraying device for photovoltaic brackets is a device specially used to spray paint on the surface of the pipe piles used in photovoltaic brackets, and plays a key role in the photovoltaic industry. Its main function is to improve the protective performance and aesthetics of the pipe piles by evenly covering the surface of the pipe piles with paint. The positioning of traditional photovoltaic bracket pipe piles mostly relies on tooling fixtures of fixed specifications. Due to the lack of equipment that can adapt to a variety of pipe diameters, each time the pipe pile diameter is changed, a lot of time is spent on replacing the tooling, which seriously affects the installation progress. In the past, manual measurement and adjustment were mostly used to position the pipe piles. In actual operation, positioning deviations often occur due to factors such as worker experience and fatigue.

Then, the motor drives the screw rod to rotate, and then drives the screw rod sleeve to perform linear lifting movement on its outer wall. As the screw rod sleeve moves upward, it will drive the auxiliary rod to move synchronously on the outer wall of the connecting rod;
[0019] Step 2: As the auxiliary rod moves upward, the connecting head at the end of the connecting rod can be pushed to rotate upward outside the movable block. At this time, the other end of the connecting rod pushes the anti-slip support block to move outward through the connecting block, thereby expanding the support range, making it easier to push the anti-slip support block close to the inner wall of the photovoltaic bracket pile, and realize the positioning of photovoltaic bracket piles of different sizes;

[0021] Step 4: As the movable frame moves, the support frame will move synchronously. At this time, the motor 1 drives the screw rod 2 to rotate, and the screw rod slider immediately drives the movable plate to rise and fall linearly on the outer wall of the slide rod, so that the spraying height of the spray machine frame can be flexibly adjusted;
[0022] Step 5: As the movable frame and the support frame move circumferentially around the outer wall of the gear ring, the spraying frame can be driven to spray along the outer wall of the photovoltaic support pile without dead angles. At the same time, the spraying height of the spraying frame can be further adjusted by adjusting the screw assembly;
[0023] Step 6: The paint can be sprayed out through the spray port to spray the photovoltaic bracket pipe pile, which greatly improves the overall flexibility. Subsequently, the electric push rod pushes the scraper to move close to the pipe pile to scrape off the excess paint, and the paint drips down into the collection chamber for collection.
[0024] In summary, the present invention includes the following beneficial technical effects:
[0025] In the present application, the pipe piles are placed on the supporting mesh plate, and the screw rod causes the screw rod sleeve to rise and fall, driving the auxiliary rod, connecting rod and other components to operate, so that the anti-slip support block can be quickly expanded to fit the inner walls of pipe piles of different diameters. There is no need for manual adjustment or replacement of complex tooling, which greatly shortens the preparation time and reduces tooling costs.
[0026] During the spraying operation, the gear meshes with the gear ring, driving the movable frame to move around the spray material seat in a circumferential direction, and the guide rod and pulley cooperate to ensure smooth movement. At the same time, the height of the spraying machine frame is adjusted by driving the moving plate through the screw assembly to achieve spraying without dead angles, ensuring that all parts of the pipe pile can be evenly covered with paint, improving the product's protective performance and aesthetics. The stable movement state ensures the spraying effect, reduces the defective rate, and the automated operation greatly improves production efficiency and meets the needs of large-scale production.

DETAILED DESCRIPTION
[0034] The following is combined with Figure 1-6 The present invention is described in further detail.
[0035] The embodiment of the present invention discloses a pipe pile spraying device for a photovoltaic support. Figure 1-Figure 4, including a spray material seat 1, a supporting mesh plate 2 is provided inside the spray material seat 1, a collecting chamber 11 is provided inside the spray material seat 1, and a group of reinforcing rods 12 supporting the supporting mesh plate 2 are fixed to the inner wall of the collecting chamber 11 at equal intervals along the circumferential direction.

The photovoltaic bracket pipe pile is placed on the supporting mesh plate 2, and the supporting mesh plate 2 is set to be a filter screen shape, which can filter the paint. Then the motor is started to drive the screw rod 21 to rotate, and the screw rod sleeve 26 rises and falls linearly accordingly.

A movable opening 28 is opened inside both ends of the auxiliary rod 27, and the two ends of the auxiliary rod 27 are respectively rotatably connected to the connecting rod 24 and the screw sleeve 26. With the lifting and lowering of the screw sleeve 26, the auxiliary rod 27 can be driven to move synchronously on the outer wall of the connecting rod 24. When the auxiliary rod 27 moves upward, the connector 25 at the end of the connecting rod 24 is prompted to rotate upward outside the movable block 23, so that the other end of the connecting rod 24 pushes the anti-slip support block 22 to open outward through the connecting block 29, which can quickly expand the support range and fit the inner wall of the photovoltaic bracket pipe pile with different pipe diameters. In the past, for photovoltaic support piles with different pipe diameters, it was often necessary to customize a variety of different specifications of fixtures, which was costly and took up a lot of storage space. By adopting adjustable support components, it is possible to flexibly position piles of various pipe diameters.

While the movable frame 6 moves, the screw slider 55 drives the movable plate 56 to rise and fall linearly on the outer wall of the slide rod 53, and flexibly adjusts the spraying height of the spray machine frame 7. The synergistic effect of various components enables the spray machine frame 7 to move in all directions along the outer wall of the photovoltaic support pipe pile, realizing spraying without dead angles, ensuring that all parts of the pipe pile can be evenly covered with paint, and improving the protection performance and aesthetics of the product.
