To make the purpose, technical solution and advantages of this application clearer, the implementation mode of this application will be further described in detail below in conjunction with the accompanying drawings.

[0032] In view of the problems that manual coating of the inner wall of steel cylinders is cumbersome and difficult to control the coating quality, please combine Figures 1 to 4 The present application provides a rotary paint spraying device in a steel cylinder, which includes a support member 1, a rotary swing arm 2 and a spray member 3. The support member 1 is arranged at the middle position inside the steel cylinder, and the spray member 3 is arranged on the rotary swing arm 2. The rotary swing arm 2 can rotate 360° around the support member 1 in the steel cylinder, thereby driving the spray member 3 to spray the inner wall of the steel cylinder circumferentially, with high spraying efficiency and better stability.

[0033] Specifically, the support member 1 includes a vertical steel pipe 11 disposed at the center of the steel cylinder and extending in the vertical direction. A rotating member 4 is disposed between the rotating swing arm 2 and the support member 1 for enabling the rotating swing arm 2 to rotate relative to the support member 1. The rotating member 4 includes a connecting sleeve 41 sleeved on the vertical steel pipe 11 and a connecting plate 42 fixed on the outer wall of the connecting sleeve 41. The connecting sleeve 41 and the vertical steel pipe 11 are clearance-matched. The rotating swing arm 2 is connected to the connecting plate 42, thereby realizing a rotatable connection between the rotating swing arm 2 and the vertical steel pipe 11. In this embodiment, the connecting sleeve 41 is a steel pipe with an inner diameter greater than the outer diameter of the vertical steel pipe 11, and the connecting plate 42 is a steel plate with a thickness of 8 mm, which is welded to the steel pipe serving as the connecting sleeve 41.

[0034] A stopper for limiting the vertical position of the rotating member 4 along the vertical steel pipe 11 is inserted into the vertical steel pipe 11. At the same time, a reserved hole 12 for the stopper to pass through is opened on the vertical steel pipe 11. The stopper can be set as a stopper rod or a stopper bolt passing through the reserved hole 12. The stopper can be supported below the connecting sleeve 41 to limit the downward movement of the rotating member 4 under the action of its own gravity, so that the rotating swing arm 2 can rotate at a fixed height position of the vertical steel pipe 11. In addition, a plurality of reserved holes 12 are arranged at intervals along the length direction of the vertical steel pipe 11, so as to be suitable for limiting the rotating member 4 and the rotating swing arm 2 at different height positions of the vertical steel pipe 11, so as to realize the painting of different height positions of the inner wall of the steel cylinder.

[0035] The rotating swing arm 2 includes a rotating steel pipe 21 and a fixed plate 22. The rotating steel pipe 21 extends radially along the vertical steel box, that is, when the rotating steel pipe 21 is installed on the vertical steel pipe 11 through the rotating member 4, the rotating steel pipe 21 and the vertical steel pipe 11 are perpendicular to each other. The fixed plate 22 is arranged at the end of the rotating steel pipe 21 close to the vertical steel pipe 11. The fixed plate 22 in this embodiment is set to a steel plate with the same size as the connecting plate 42 and a thickness of 8 mm. The fixing plate 22 and the connecting plate 42 are connected and fixed by bolts to achieve the purpose of connecting the rotating swing arm 2 with the rotating member 4.

[0036] The spraying part 3 of the present application is installed on the rotating swing arm 2, so that the inner wall of the steel cylinder is circumferentially sprayed with paint as the rotating swing arm 2 rotates. The spraying part 3 includes a nozzle 31 and a spraying pipe 32. The nozzle 31 is installed at the end of the rotating steel pipe 21 away from the vertical steel pipe 11. One end of the spraying pipe 32 is connected to the nozzle 31, and the other end is connected to the paint bucket to transport the paint in the paint bucket to the nozzle 31. At the same time, the spraying pipe 32 in this embodiment is wound on the rotating steel pipe 21, and the spraying pipe 32 extends from the nozzle 31 to the vertical steel pipe 11 located at the center of the steel cylinder along the length direction of the rotating steel pipe 21. The paint bucket can be placed at the bottom of the vertical steel pipe 11, so as to avoid the phenomenon that the spraying part 3 is thrown around without support and limitation when rotating with the rotating swing arm 2, thereby improving the safety of construction.

[0037] In a preferred embodiment, the vertical steel pipe 11 is made of a steel pipe with a diameter of 48 mm, and the diameter of the reserved hole 12 opened on the vertical steel pipe 11 is 10 mm. The diameter of the limit rod or the limit bolt inserted on the vertical steel pipe 11 is also 10 mm. The connecting sleeve 41 of the rotating part 4 is made of a steel pipe with a diameter of 60 mm. The connecting sleeve 41 is sleeved on the vertical steel pipe 11 and has a gap with the vertical steel pipe 11. The rotating steel pipe 21 of the rotating swing arm 2 is made of a square steel pipe with a side length of 25 mm.

[0038] In addition, in order to prevent the steel cylinder from deforming during the construction process, a cross-shaped support frame 5 is also provided inside the steel cylinder. The support frame 5 includes a center disk 51 and a support rod 52. The center disk 51 can be installed on the vertical steel pipe 11 for positioning. A plurality of support rods 52 are provided along the circumference of the center disk 51, and each support rod 52 extends along the radial direction of the center disk 51. The end of the support rod 52 away from the center disk 51 abuts against the inner wall of the steel cylinder to play a supporting role. Further, the end of the support rod 52 away from the center disk 51 is provided with an adjustment rod 53 for extending the length of the support rod 52, which can meet the internal support of steel cylinders of different sizes. The adjustment rod 53 is inserted into the support rod 52 and is threadedly connected with the support rod 52, and a support plate is provided at the outer end of the support rod 52 where the adjustment rod 53 is located. The support plate can increase the contact area between the end of the adjustment rod 53 and the inner wall of the steel cylinder, thereby improving the support capacity of the support rod 52 for the steel cylinder.

[0039] In summary, the structure of the rotary paint spraying device in the steel cylinder of the present application is simple, and the rotary swing arm 2 is used to rotate 360° with the support 1 located in the center of the steel cylinder as the axis for spraying, which is easy to operate. In combination with the characteristics of the cylinder, the distance from the rotary swing arm 2 to the inner wall of the steel cylinder is the same, and the spraying effect is the same, and it is easy to control the spraying quality. After completing a circle of spraying in the steel cylinder, manually adjust the position of the rotating part 4 on the vertical steel cylinder to adjust the height position of the rotary swing arm 2, and then the spraying operation of different elevation sections in the steel cylinder can be completed, and the construction efficiency is high. After the spraying operation is completed, the rotary paint spraying device in the steel cylinder of the present application can also be dismantled for turnover use to reduce construction costs.

[0040] The above description is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
