[0031] Combine the following Figures 1 to 7 , describing an embodiment of the present invention.

[0032] According to an embodiment of the present invention, Figures 1 to 7As shown, a painting device for steel structure is provided, comprising: a support seat 1, a flip assembly 3, a sprayer 4, a drive assembly 5 and a linkage assembly 6. A dust cover 2 is installed on the upper surface of the support seat 1. The flip assembly 3 is rotatably arranged on the side wall surface of the dust cover 2, and the side wall of the dust cover 2 is provided with an installation port, and the flip assembly 3 is arranged corresponding to the installation port. The flip assembly 3 has a clamping structure 303, and the clamping structure 303 is suitable for clamping the steel structure. The installation position of the steel structure is formed in the dust cover 2 corresponding to the installation port. The sprayer 4 is arranged in the dust cover 2, and the sprayer 4 is provided with a feed port. A storage structure 9 is arranged on the top outer side of the dust cover 2, and the storage structure 9 is connected to the feed port. The drive assembly 5 is connected to the sprayer 4 in a transmission manner so that the sprayer 4 reciprocates along the length direction of the installation position. The linkage assembly 6 is suitable for driving the flip assembly 3 to rotate under the drive of the drive assembly 5.

[0033] By setting up the flip component 3 to fix the steel structure, and using the driving component 5 to drive the linkage component 6 to move, the flip component 3 is further driven to flip, so that after the painting work is completed on one side of the steel structure, there is no need to manually turn the steel structure over, avoiding manual scratches on the paint surface, saving manpower, and improving the spraying efficiency of the steel structure's painting device.

[0034] Specifically, by providing the dust cover 2, the anti-rust paint is prevented from polluting the surrounding environment during the spraying process, thereby improving the environmental protection performance of the paint spraying device for steel structures.

[0035] Specifically, Figure 2 As shown, the installation position is the position between the flip components 3 arranged on the two side walls of the dust cover 2.

[0036] In one embodiment, Figure 1 and Figure 2 As shown, the flip assembly 3 includes a flip disc 301 and a locking member 302. The flip disc 301 is arranged corresponding to the installation port, and a plurality of threaded holes are opened along the circumference of the flip disc 301. A plurality of locking members 302 are arranged, and the plurality of locking members 302 respectively penetrate the plurality of threaded holes to form a clamping structure 303, and can be arranged in contact with the steel structure. By arranging a plurality of locking members 302 to fully clamp the steel structure, the position of the steel structure is prevented from being offset during the painting process, and the painting quality of the surface of the steel structure is improved.

[0037] Specifically, in this embodiment, Figure 2 As shown, there are two flip disks 301, which are arranged corresponding to the two side walls of the dust cover 2. The steel structure is passed through the two flip disks 301, and then the locking piece 302 is rotated to make the locking piece 302 tightly abut against the steel structure, thereby fixing the steel structure in the installation position.

[0038] In one embodiment, Figure 2 and Figure 3 As shown, the painting device for steel structure also includes a cleaning component 7, which is connected to one side of the sprayer 4. By setting the cleaning component 7, a large amount of impurities on the surface of the steel structure is avoided, and the quality of the steel structure surface after painting is improved.

[0039] Specifically, in this embodiment, Figure 2 As shown, the cleaning component 7 is arranged on the right side of the sprayer 4, that is, the side where the sprayer 4 is not spraying the steel structure. The cleaning component 7 is arranged in this way to clean the impurities on the surface of the steel structure first, and then spray the paint on the surface, so as to avoid the influence of impurities on the quality of anti-rust paint spraying, thereby improving the quality of spraying of the spraying device for steel structure, and also improving the spraying uniformity of the spraying device. In addition, manual cleaning cannot be performed before spraying, and the cleaning component 7 is used to realize automatic cleaning of impurities, thereby improving the spraying efficiency of the spraying device for steel structure.

[0040] In one embodiment, Figure 2 and Figure 3 As shown, the cleaning assembly 7 includes a mounting portion 701, a rotating portion 702, a knocking portion 703 and a cleaning portion 704. The mounting portion 701 is connected to the sprayer 4. The rotating portion 702 can be rotatably arranged on the mounting portion 701. The knocking portion 703 is arranged on the mounting portion 701 and is vertically close to or away from the mounting position. The first end of the cleaning portion 704 is transmission-connected to the rotating portion 702, and the second end of the cleaning portion 704 is arranged close to the mounting position. The knocking portion 703 is arranged to knock on the steel structure, and the cleaning portion 704 is arranged to clean the impurities loosened by knocking on the steel structure, thereby realizing automatic cleaning of the outer surface of the steel structure and improving the quality of the steel structure surface after painting.

[0041] In one embodiment, Figure 3As shown, the mounting portion 701 includes a mounting plate 7011 and a fixed plate 7012, two mounting plates 7011 are arranged at a relative interval, the two mounting plates 7011 are respectively connected to the spraying machine 4, and the two ends of the fixed plate 7012 are respectively connected to the two mounting plates 7011. The rotating portion 702 includes a rotating rod 7021 and a rotating disk 7022. The two ends of the rotating rod 7021 are respectively rotatably connected to the two mounting plates 7011. The rotating rod 7021 is arranged above the fixed plate 7012. A plurality of rotating disks 7022 are arranged, and the plurality of rotating disks 7022 are spaced apart and sleeved on the rotating rod 7021. A plurality of fixing holes are opened on the fixed plate 7012, and the plurality of fixing holes are aligned with each other. Several rotating disks 7022 should be set, the knocking part 703 passes through the fixing hole, and several convex point structures 70221 are arranged at intervals on the outer periphery of the rotating disk 7022. The several convex point structures 70221 are suitable for being abutted against the upper end of the knocking part 703 in sequence, and the lower end of the knocking part 703 is arranged toward the installation position. A first bevel gear 7023 is also arranged on the rotating rod 7021. The cleaning part 704 includes a positioning rod and a fan blade part 7042. The first end of the positioning rod is provided with a second bevel gear 7041, and the first bevel gear 7023 and the second bevel gear 7041 are meshed. The second end of the positioning rod is connected to the fan blade part 7042, and the fan blade part 7042 is arranged close to the installation position.

[0042] Specifically, during the rotation of the fan blade 7042, impurities knocked off the surface of the steel structure by the knocking part 703 can be blown away, which is beneficial to improving the spraying quality.

[0043] Specifically, in this embodiment, Figure 2 As shown, a rotating gear 7024 is provided at one end of the rotating rod 7021, and a fixed rack 201 is also provided in the dust cover 2. The fixed rack 201 is arranged along the length direction of the steel structure, and the rotating gear 7024 is meshed with the fixed rack 201 to enable the rotating rod 7021 to rotate.

[0044] Specifically, in this embodiment, Figure 3 and Figure 7 As shown, a first spring member 7031 is fixedly installed on the lower surface of the fixed plate 7012, and a mounting ring 7032 is provided at one end of the first spring member 7031 away from the fixed plate 7012. The knocking part 703 is penetrated and arranged in the spring member and the mounting ring 7032. The upper end of the knocking part 703 penetrates the fixed plate 7012 and can be abutted against the protrusion structure 70221 on the outer periphery of the rotating disk 7022. The lower end of the knocking part 703 extends to the lower side of the mounting ring 7032 and knocks the steel structure.

[0045] It should be noted that, by setting the first spring member 7031 to be connected with the mounting ring 7032, and connecting the mounting ring 7032 with the knocking part 703, when the rotating rod 7021 rotates to drive the rotating disk 7022 to rotate, the protrusion structure 70221 on the rotating disk 7022 presses the knocking part 703 downward, and the knocking part 703 moves downward to knock on the surface of the steel structure. At this time, the first spring member 7031 is stretched downward. After the knocking part 703 completes a knock, the first spring member 7031 shrinks upward under the drive of the elastic force, thereby driving the knocking part 703 to move upward, so that the knocking part 703 and the protrusion structure 70221 can abut against each other again, thereby realizing another knocking movement of the knocking part 703.

[0046] It should be further explained that, by setting the cleaning component 7, the sprayer 4 will drive the mounting plate 7011 to move synchronously when it moves. At this time, the mounting plate 7011 drives the rotating gear 7024 to move on the fixed rack 201 through the rotating rod 7021, so that the rotating rod 7021 will rotate under the action of the fixed rack 201. At this time, the rotating rod 7021 will drive the rotating disk 7022 and the first bevel gear 7023 to rotate. When the rotating disk 7022 rotates, it will drive the convex point structure 70221 to rotate synchronously. Under the action of the convex point structure 70221, the The striking part 703 strikes the steel structure under the action of the spring part and the mounting ring 7032, and then under the action of the first bevel gear 7023, the second bevel gear 7041 drives the positioning rod to rotate and drives the fan blade part 7042 to rotate. The wind generated by the fan blade part 7042 cleans the impurities loosened by the knocking on the steel structure, thereby preventing the impurities from affecting the quality of the anti-rust paint spraying, improving the spraying quality of the spraying device, and also improving the spraying uniformity of the spraying device. There is no need for manual cleaning before spraying, thereby improving the spraying efficiency of the paint spraying device for steel structures.

[0047] In one embodiment, Figure 2As shown, the cleaning part 704 also includes a collecting box 7043, a scraper rod 7044 and a scraper plate 7045. The upper end of the scraper rod 7044 is connected to the mounting plate 7011, the side of the scraper rod 7044 is fitted with the inner wall surface of the dust cover 2, the lower end of the scraper rod 7044 is connected to the scraper plate 7045, the scraper plate 7045 is fitted with the upper surface of the support seat 1, a limiting structure 101 is provided on the lower surface of the support seat 1, the collecting box 7043 is arranged in the limiting structure 101, the support seat 1 is provided with a discharge groove 102, the discharge groove 102 passes through the support seat 1 and is connected to the collecting box 7043. By setting up a scraper rod 7044 and a scraper plate 7045, the anti-rust paint splashed by the sprayer 4 onto the inner wall of the dust cover 2 and the support seat 1 can be cleaned. By setting up a collecting box 7043, the anti-rust paint cleaned by the scraper rod 7044 and the scraper plate 7045 can be collected to avoid polluting the environment, thereby improving the environmental protection performance of the steel structure spraying device.

[0048] Specifically, when the mounting plate 7011 moves, it will drive the scraper rod 7044 to move, and the scraper rod 7044 will drive the scraper plate 7045 to move. When the scraper rod 7044 moves, it will clean the anti-rust paint on the inner wall of the dust cover 2, and the scraper plate 7045 will clean the anti-rust paint on the upper surface of the support seat 1. The cleaned anti-rust paint falls into the collection box 7043 through the discharge trough 102. When the anti-rust paint in the collection box 7043 reaches a certain amount, the collection box 7043 is pulled down for cleaning through the limiting structure 101.

[0049] Specifically, Figure 2 , Figure 5 and Figure 6 As shown, the limiting structure 101 is a limiting groove arranged at intervals, and a protrusion 70431 is arranged on the outer periphery of the collection box 7043. The protrusion 70431 is correspondingly inserted into the limiting groove and slidably connected in the limiting groove, so that the collection box 7043 and the support seat 1 can be detachably connected.

[0050] Specifically, Figure 2 As shown, several discharge troughs 102 are provided, several limiting structures 101 are provided, and several collecting boxes 7043 are provided. By providing several discharge troughs 102, several limiting structures 101 and several collecting boxes 7043, it is beneficial to fully collect the anti-rust paint and avoid polluting the environment.

[0051] In one embodiment, Figure 2 As shown, the driving assembly 5 includes a motor 501 and a threaded rod 502. The threaded rod 502 is arranged along the length direction of the steel structure. A slider 503 is sleeved on the threaded rod 502. The slider 503 is connected to the sprayer 4. One end of the threaded rod 502 passes through the side wall of the dust cover 2 and is transmission-connected to the motor 501.

[0052] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the outer surface of the motor 501 is covered with a mounting cover 8 to avoid damage to the motor 501 .

[0053] Specifically, in this embodiment, when the motor 501 drives the threaded rod 502 to rotate forward, the slider 503 drives the continuous sprayer 4 to move. When the sprayer 4 moves, the anti-rust paint in the storage structure 9 is sprayed onto the outer surface of the steel structure through the connecting pipe. When the motor 501 drives the threaded rod 502 to rotate reversely, the sprayer 4 returns to the starting position of spraying to prepare for the next spraying.

[0054] Specifically, when the sprayer 4 returns to the starting position of spraying, the sprayer 4 will not work. During the flipping of the steel structure, the knocking part 703 will not contact the steel structure. The fan blade 7042 will continue to rotate, which is beneficial to drying the anti-rust paint on the surface of the steel structure. The scraper rod 7044 and the scraper plate 7045 will continue to scrape the inner wall of the dust cover 2 and the upper surface of the support seat 1, and collect the anti-rust paint into the collection box 7043.

[0055] In one embodiment, Figure 2 and Figure 4 As shown, the linkage assembly 6 includes a ratchet structure 601 and a transmission structure 602. One side of the ratchet structure 601 is transmission-connected to the drive assembly 5, and the other side of the ratchet structure 601 is transmission-connected to the transmission structure 602. The transmission structure 602 is transmission-connected to the flip assembly 3. When the motor 501 drives the threaded rod 502 to rotate forward, the ratchet structure 601 is in a stationary state. When the motor 501 drives the threaded rod 502 to rotate reversely, the ratchet structure 601 rotates with the threaded rod 502.

[0056] Specifically, Figure 2 As shown, the threaded rod 502 rotates in the positive direction to enable the sprayer 4 to move along the Figure 2 The thread direction moves from left to right in the middle, and the threaded rod 502 rotates in the opposite direction to enable the spraying machine 4 to move along Figure 2 The thread direction moves from right to left.

[0057] In one embodiment, Figure 4As shown, the ratchet structure 601 includes a driving rod 6011, a ratchet ring 6012, a fixed disk 6013 and a ratchet body 6014. The driving rod 6011 passes through the side wall of the dust cover 2 and is rotatably arranged. One end of the driving rod 6011 arranged in the dust cover 2 is provided with a mounting groove 60111, and a connecting block 6015 is arranged in the mounting groove 60111. The first end of the connecting block 6015 is rotatably connected to the driving rod 6011, and the second end of the connecting block 6015 is transmission-connected to one end of the threaded rod 502 close to the driving rod 6011. The ratchet ring 6012 is embedded in the mounting groove 6011, and the fixed disk 6013 is sleeved on the connecting block 6015. The ratchet body 6014 is rotatably arranged on the side wall of the fixed disk 6013 and is meshing with the ratchet ring 6012.

[0058] Specifically, Figure 4 As shown, when the threaded rod 502 rotates forward, the ratchet ring 6012 and the ratchet body 6014 are not engaged, and thus will not drive the drive rod 6011 to rotate, and the drive rod 6011 is in a stationary state. When the threaded rod 502 rotates reversely, the ratchet ring 6012 and the ratchet body 6014 are engaged, thereby driving the drive rod 6011 to rotate, and the rotation of the drive rod 6011 drives the first gear 6021 to rotate, and the first gear 6021 drives the second gear 6022 to rotate, thereby further driving the flip disk 301 to rotate, that is, the steel structure rotates and flips over.

[0059] Specifically, in this embodiment, Figure 4 As shown, a protruding plate 6017 is arranged on the side wall surface of the fixed disk 6013, and the protruding plate 6017 is connected to one end of the second spring member 6016, and the other end of the second spring member 6016 is connected to the ratchet body 6014. By arranging the second spring member 6016, the ratchet body 6014 can be subjected to the elastic force of the contraction of the second spring member 6016 during the rotation process, so that the ratchet body 6014 can return to the preset position.

[0060] In one embodiment, Figure 2 As shown, the transmission structure 602 includes a first gear 6021 and a second gear 6022.
