DETAILED DESCRIPTION

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0025] like Figure 1As shown, a painting device for a steel structure includes a support frame 1, on which a conveying mechanism 2 and two rotating spraying mechanisms 3 are provided. The two rotating spraying mechanisms 3 are symmetrically arranged up and down and are both connected to the conveying mechanism 2. Two sleeve sliding frames 4 are sleeved on the support frame 1, and supporting plates 6 are respectively provided on the left and right sides of the support frame 1, one of the supporting plates 6 is L-shaped, and the other supporting plate 6 is T-shaped. The two supporting plates 6 are respectively fixedly connected to both sides of the upper surface of the sleeve sliding frame 4, and the left and right sides of the bottom surface of the sleeve sliding frame 4 are respectively fixed with support columns 5, and the lower sides of the two support columns 5 are provided with universal wheels.

[0026] The transmission mechanism 2 includes two transfer shafts 21, on which overlapping rollers are fixed. Both sides of the two transfer shafts 21 are rotatably cooperated with the first fixed plate 22. The first fixed plate 22 is fixed on the support frame 1. Two transmission shafts 24 and a pulley group 23 are provided above the support frame 1. The pulley group 23 is connected to one side of the two transfer shafts 21, and a transmission mechanism is provided on both sides of one of the transfer shafts 21.

[0027] As an optional embodiment, the transmission mechanism includes a rotating shaft 27 and a transmission shaft 24, the transmission shaft 24 is connected to one side of one of the transfer shafts 21, and a first bevel gear 25 is fixedly provided on the other side of the rotating shaft 27, and a second bevel gear 26 is fixedly provided on one side of the transmission shaft 24, and the second bevel gear 26 is meshed with the first bevel gear 25. A second fixed plate 28 is fixedly provided on the support frame 1, and the second fixed plate 28 rotates with the rotating shaft 27. A third fixed plate 29 is fixedly provided on the side of the second fixed plate 28, and the third fixed plate 29 rotates with the transmission shaft 24. The transmission ratio of the second bevel gear 26 to the first bevel gear 25 is set to 3:1, so that the transfer shaft 21 can rotate one circle, driving the rotating shaft 27 to rotate 3 circles, thereby driving the slide rail on the transfer spraying mechanism 3 to slide 3 times in a cycle, so that the spraying mechanism can be driven to spray three times in a cycle, thereby improving the paint spraying effect.

[0028] Refer to the attached Figure 2 A motor 210 is provided on the support frame 1, and the output shaft of the motor 210 is connected to one of the rotating shafts 27. A fourth fixed plate 211 is fixed on the support frame 1. The fourth fixed plate 211 rotates with the output shaft of the motor 210. With this arrangement, the motor 210 can drive one of the rotating shafts 27 to rotate while driving the second bevel gear 26 to engage and drive the first bevel gear 25 and the transmission shaft 24 to rotate synchronously, thereby driving the transfer shaft 21 to rotate, so that the steel structure overlapped on the transfer shaft 21 can be moved and transported.

[0029] Refer to the attached Figure 3The spraying mechanism 3 includes a semicircular plate 31 and a conveying pipe 37. The semicircular plate 31 is set to a semicircular ring shape. The semicircular plate 31 is fixed on the support frame 1. A slide rail mechanism and a spraying mechanism are provided on the semicircular plate 31, and the slide rail mechanism includes multiple inner sleeve shafts 33. A semicircular hole 32 is opened on the support frame 1. Multiple inner sleeve shafts 33 are all sleeved in the semicircular hole 32. Two stabilizing plates 34 are correspondingly provided on the opposite sides of the semicircular plate 31. The two stabilizing plates 34 are fixedly connected with multiple inner sleeve shafts 33. Such an arrangement allows the stabilizing plate 34 to rely on the sleeve connection between the inner sleeve shaft 33 and the semicircular hole 32, so that the slide rail mechanism can be restricted to slide in the semicircular hole 32, thereby limiting the moving trajectory of the slide rail mechanism and ensuring that the spraying mechanism fully sprays the steel structure.

[0030] Furthermore, the spraying mechanism includes a mounting plate 35 and a delivery pipe 37. The mounting plate 35 is set to an arc shape. The mounting plate 35 is fixed to the side of one of the stabilizing plates 34. A plurality of spray heads 36 are provided on the mounting plate 35. The plurality of spray heads 36 are all connected to the delivery pipe 37. The delivery pipe 37 is connected to an external paint delivery pump. With such a setting, the steel structure can be sprayed with the help of a plurality of spray heads 36, thereby increasing the spraying range. In this way, driven by the slide rail mechanism, the paint coverage range of the moving steel structure can be increased, thereby improving the mobile spraying effect.

[0031] Refer to the attached Figure 4 A push-pull mechanism is provided on the side of the semicircular plate 31, and the push-pull mechanism includes a rotating plate 310 and a push-pull plate 39. One side of the rotating plate 310 is fixedly connected to the other side of one of the rotating shafts 27, and one side of the push-pull plate 39 rotates with the other side of the rotating plate 310. A fixed shaft 38 is correspondingly provided on the side of the semicircular plate 31, and the fixed shaft 38 is fixedly connected to the side of another stable plate 34. The fixed shaft 38 rotates with the other side of the push-pull plate 39. With such a setting, the push-pull mechanism can be driven by the motor 210, so that when the rotating plate 310 rotates in a cycle, the push-pull plate 39 is pulled to drive the slide rail to slide in a cycle along the semicircular hole 32, so that it is convenient to carry out mobile spraying operations on moving steel structures.

[0032] The second bevel gear 26 on the rotating shaft 27 is meshed with the second bevel gear 26 on the rotating shaft 27 to drive the first bevel gear 25 and the transmission shaft 24 to rotate. The transmission shaft 24 drives the transfer shaft 21 to rotate synchronously. At the same time, the two rotating shafts 27 are driven to rotate synchronously by the pulley group 23. In this way, the steel structure overlapped on the overlapping roller on the transfer shaft 21 can be rotated and transmitted. At the same time, the rotating shaft 27 drives the rotating plate 310 on the push-pull mechanism to rotate synchronously, so that the rotating plate 310 drives the push-pull plate 39 to pull the stabilizing plate 34 on the slide rail mechanism to move. The stabilizing plate 34 relies on the inner sleeve shaft 33 to be connected with the semicircular hole 32 on the semicircular plate 31, so that the stabilizing plate 34 can slide along the semicircular hole 32. At the same time, the stabilizing plate 34 drives the multiple spray heads 36 on the spraying mechanism to fully spray the steel structure transported by the transfer shaft 21. In this way, the steel structure can be mobile sprayed, thereby improving the spraying efficiency.

[0033] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
