Description

Technical Field

[0001] This utility model belongs to the field of steel structure anti-corrosion technology, specifically relating to an anti-corrosion treatment device for prefabricated building steel structures. Background Technology

[0002] In the modern construction industry, steel structures are widely used in various building structures due to their advantages such as high strength, light weight, and fast construction speed. However, steel structures are susceptible to corrosion during use, which reduces their structural performance and service life, especially in coastal areas. Therefore, effective anti-corrosion treatment of steel structures is an important measure to ensure building safety and extend their service life.

[0003] Currently, one of the common methods for anti-corrosion treatment of steel structures is spraying anti-corrosion materials. This method involves uniformly spraying anti-corrosion coatings onto the surface of the steel structure to form a protective layer, thereby achieving the purpose of anti-corrosion. However, existing spraying technologies have certain limitations.

[0004] For example, when painting large steel structure workpieces, the painting equipment cannot complete the painting of the entire workpiece in one go due to its large size. Therefore, the workpiece needs to be fixed on a specific clamping device for painting in sections. Existing clamping devices are usually designed to be fixed, meaning the workpiece is fixed in one position during the painting process. When another part of the workpiece needs to be painted, the operator must remove the workpiece from the clamping device, readjust its position, and fix it again before painting can continue. This operating method has the following problems:

[0005] Frequent disassembly and reassembly of workpieces is not only time-consuming, but also increases the labor intensity of operators. Due to the need to adjust the position of the workpieces multiple times, the efficiency of the entire spraying process is low, and the production cycle is extended. During the disassembly and reassembly of workpieces, there may be slight changes in the position of the workpieces, which will affect the uniformity of spraying and the quality of the coating.

[0006] Therefore, there is an urgent need for an improved anti-corrosion treatment device for prefabricated building steel structures to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a prefabricated steel structure anti-corrosion treatment device that can adjust the position of the workpiece being clamped, reduce the disassembly and installation of the workpiece during the process of spraying the coating, continuously complete the spraying work of the workpiece, and reduce the workload of the operator during the spraying process.

[0008] The specific technical solution adopted by this utility model is as follows:

[0009] A prefabricated steel structure anti-corrosion treatment device includes a working plane, a sprayer installed on the top of the working plane, a movable frame installed on the top of the working plane, an installation frame installed on the top of the movable frame, a rotating frame rotatably connected to one end of the installation frame, and the installation frame and the rotating frame are located below the sprayer.

A first motor is installed on the outside of the rotating frame, and the output end of the first motor passes through the rotating frame and is connected to one of the first meshing gears. All of the multiple first meshing gears are meshed with the first ring gear.

[0012] Multiple movable clamping blocks are slidably connected inside the rotating frame and at positions corresponding to the annular guide rail. The multiple movable clamping blocks are arranged in a circle with the center of the rotating frame as the center. Each of the multiple movable clamping blocks has a meshing rack on the side near the annular guide rail, and the meshing rack is meshed with the annular guide rail.

[0013] Multiple movable clamping blocks are rotatably connected to one end of each other, and a second motor is installed on one side of each movable clamping block. The output end of the second motor passes through the movable clamping block and is connected to the center of one of the drive wheels.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1-5As shown, a prefabricated steel structure anti-corrosion treatment device includes a working plane 1. A sprayer 5 is installed on the top of the working plane 1. A heater 22 is also installed on the outside of the sprayer 5. When the sprayer 5 sprays the workpiece, the heater 22 can be activated to dry the anti-corrosion material sprayed by the sprayer 5, so that it can dry quickly and prevent the anti-corrosion material from being wiped off when personnel handle it or the machine operates on it in subsequent work. A movable frame 2 is also installed on the top of the working plane 1. An installation frame 3 is installed on the top of the movable frame 2. A rotating frame 4 is rotatably connected to one end of the installation frame 3. The installation frame 3 and the rotating frame 4 are located below the sprayer 5. A clamping groove 21 is provided at the center of the rotating frame 4 and extends through to the middle of the installation frame 3.

[0028] When performing anti-corrosion treatment on workpieces such as round tubes or cylinders, the workpiece can be inserted into the clamping groove 21 to achieve anti-corrosion treatment. The mechanism for clamping the workpiece is as follows:

[0029] The rotating frame 4 is also equipped with a clamping mechanism, which is used to clamp the workpiece.

[0030] See attached document Figure 3-4 The clamping mechanism includes a rotating plate 7 rotatably connected inside the rotating frame 4. A first ring gear 8 and a ring guide rail 9 are respectively provided on one side and the other side of the rotating plate 7. Multiple first meshing gears 6 are rotatably connected inside the rotating frame 4 and at the corresponding position of the first ring gear 8. A first motor 12 is installed on the outside of the rotating frame 4, and the output end of the first motor 12 passes through the rotating frame 4 and is connected to one of the first meshing gears 6. Multiple first meshing gears 6 are all meshed with the first ring gear 8. The first meshing gear 6 is in the shape of an inverted triangle, so that when it rotates, it can more easily drive the rotating plate 7 to rotate.

[0031] Multiple movable clamping blocks 10 are slidably connected inside the rotating frame 4 and at the corresponding position of the annular guide rail 9. The multiple movable clamping blocks 10 are arranged in a circle with the center of the rotating frame 4 as the center. Each of the multiple movable clamping blocks 10 is provided with a meshing rack 11 on the side of the annular guide rail 9, and the meshing rack 11 is meshed with the annular guide rail 9.

[0032] When the output end of the first motor 12 rotates, it can drive one of the first meshing gears 6 to rotate. Through the meshing connection between the first meshing gear 6 and the first ring gear 8, the first meshing gear 6 can drive the first ring gear 8, the rotating plate 7, and the ring guide rail 9 to rotate. Through the meshing connection between the ring guide rail 9 and the meshing rack 11, when the ring guide rail 9 rotates, it can drive the meshing rack 11 and the moving clamping block 10 to move towards the center position of the clamping groove 21, thereby clamping the workpiece.

[0033] See attached document Figure 5 Multiple movable clamping blocks 10 are rotatably connected to multiple drive wheels 14 at their close ends. The outer side of each drive wheel 14 is provided with a soft pad to prevent the drive wheel 14 from clamping the workpiece with excessive force, which could cause indentations or other issues. The soft pad can be made of materials such as rubber. A second motor 13 is installed on one side of each movable clamping block 10, and the output end of the second motor 13 passes through the movable clamping block 10 and is connected to the center of one of the drive wheels 14.

[0034] When the drive wheel 14 contacts the workpiece, the sprayer 5 can be driven to spray anti-corrosion material onto the workpiece. When the spraying position needs to be changed, the second motor 13 can be driven, causing one of the drive wheels 14 to rotate. The drive wheel 14 then drives the workpiece to move horizontally, changing the contact position between the workpiece and the drive wheel 14, thereby changing the position of the workpiece. This allows the sprayer 5 to spray different positions on the workpiece.

[0035] See appendix Figure 2 A third motor 17 is mounted on the outside of the mounting frame 3. The output end of the third motor 17 is fixed with a second meshing gear 16 parallel to the rotating frame 4. A second ring gear 15 is fixed on the outside of the rotating frame 4, and the second meshing gear 16 is meshed with the second ring gear 15.

[0036] When it is necessary to change the spraying angle of the workpiece, the third motor 17 can be started, so that the output end of the third motor 17 drives the second meshing gear 16 to rotate. When the second meshing gear 16 rotates, it can drive the second ring gear 15 to rotate, and drive the rotating frame 4 to rotate, which in turn drives the rotating frame 4 and the moving clamping block 10 to rotate, changing the rotation angle of the workpiece, so that the sprayer 5 can spray the workpiece in a circle.

[0037] See appendix Figure 1 The top of the working plane 1 is provided with an installation chamber 18. The installation chamber 18 is rotatably connected with a threaded rod 19. The movable frame 2 is slidably connected inside the installation chamber 18. The movable frame 2 can be slidably connected to the installation chamber 18 through a dovetail groove or other structure. The movable frame 2 is threadedly connected to the threaded rod 19. A fourth motor 20 is also installed at one end of the installation chamber 18, and the output end of the fourth motor 20 passes through the installation chamber 18 and is connected to the threaded rod 19.

[0038] When the fourth motor 20 is driven, it can drive the threaded rod 19 to rotate, and through the threaded connection between the threaded rod 19 and the movable frame 2, and through the sliding connection between the movable frame 2 and the mounting chamber 18, the movable frame 2 can move horizontally within the mounting chamber 18, thereby spraying the end of the workpiece.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
