Description

Technical Field

[0001] This utility model relates to the field of galvanizing application technology, and in particular to an oxidation protection device for galvanizing processing. Background Technology

[0002] Hot-dip galvanizing is an effective method of metal corrosion protection, mainly used in metal structures in various industries. It involves immersing rust-removed steel parts in molten zinc, causing a zinc layer to adhere to the surface of the steel parts, thereby achieving the purpose of corrosion protection. In the existing technology, the zinc liquid will accelerate oxidation after leaving the zinc pot during the galvanizing process, resulting in zinc waste and increased costs.

[0003] CN218262686U discloses an oxidation protection device for galvanizing, characterized by comprising a connecting plate fixed to a galvanizing instrument, a fastening frame fixed to the connecting plate, a transmission structure on the fastening frame, and a pressing rod on the transmission structure that applies downward pressure. A fastening rod is hinged to the end of the pressing rod, and an arc-shaped plate is fixedly connected to the end of the fastening rod. The arc-shaped plate is positioned directly above the galvanizing connecting plate. This device prevents molten zinc from splashing out of the zinc pot, thus avoiding material waste and reducing costs, and is convenient to use. However, the arc-shaped plate is not easy to replace. When processing steel pipes of different diameters, the fixed curvature of the arc-shaped plate makes it difficult to tightly fit the tail of the steel pipe, resulting in poor equipment adaptability, high maintenance costs, and low production efficiency. This problem is particularly prominent in multi-variety, large-volume galvanizing scenarios. Therefore, an oxidation protection device for galvanizing is needed. Utility Model Content

This device can solve the problems of the arc plate being difficult to replace, and the arc plate with a fixed curvature being difficult to fit tightly to the tail of the steel pipe when processing steel pipes of different diameters, resulting in poor equipment adaptability, high maintenance costs and low production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oxidation protection device for galvanizing, comprising a galvanizing instrument and an adjustable protective structure.

The device support is positioned below the galvanizing instrument. The round rod is fixedly connected to the surface of the device support. The movable frame is rotatably sleeved on the outer surface of the round rod. There are two mounting plates, which are respectively fixedly connected to both ends of the movable frame. There are multiple mounting bolts, all of which are threadedly connected to the surface of the mounting plates. The first arc-shaped plate is bolted to the mounting plate via mounting bolts. The second arc-shaped plate is bolted to the mounting plate via mounting bolts. The positioning bolts are threadedly connected to the surface of the device support. The movable frame is threadedly connected to the positioning bolts.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Please see Figure 1-5This utility model provides a technical solution: an oxidation protection device for galvanizing, including a galvanizing instrument 1 and an adjustable protective structure. The adjustable protective structure includes a device support 11, a round rod 12, a movable frame 13, a mounting plate 14, mounting bolts 15, a first arc plate 16, a second arc plate 17, and positioning bolts 18. The device support 11 is located below the galvanizing instrument 1. The round rod 12 is fixedly connected to the surface of the device support 11. The movable frame 13 is rotatably sleeved on the outer surface of the round rod 12. There are two mounting plates 14, which are fixedly connected to both ends of the movable frame 13. There are multiple mounting bolts 15, all of which are threadedly connected to the surface of the mounting plates 14. The first arc plate 16 is bolted to the mounting plate 14 by the mounting bolts 15. The second arc plate 17 is bolted to the mounting plate 14 by the mounting bolts 15. The positioning bolts 18 are threadedly connected to the surface of the device support 11. The movable frame 13 is threadedly connected to the positioning bolts 18.

[0026] Furthermore, the surface of the movable frame 13 has two positioning screw holes 19 that are adapted to the positioning bolts 18. The top of the galvanizing instrument 1 is fixedly connected to a protective shell 2. The surface of the protective shell 2 is fixedly connected to a transparent window 3. The top of the galvanizing instrument 1 is fixedly connected to a fixed bracket 4. The top of the fixed bracket 4 is fixedly connected to a hydraulic cylinder 5. The output end of the hydraulic cylinder 5 is fixedly connected to a lifting seat 6. The top of the lifting seat 6 is fixedly connected to a limit frame 7. The limit frame 7 is slidably connected to the fixed bracket 4. The bottom of the lifting seat 6 is fixedly connected to a telescopic rod 8. The bottom of the telescopic rod 8 is fixedly connected to a connecting plate 9. The connecting plate 9 is fixedly connected to the device bracket 11. Multiple springs 10 are fixedly connected to the opposite surfaces of the lifting seat 6 and the connecting plate 9.

[0027] Furthermore, after the hydraulic cylinder 5 is started, it pushes the lifting seat 6 to slide and rise along the fixed bracket 4. The telescopic rod 8 drives the connecting plate 9 and the device bracket 11 to rise and fall as a whole. The spring 10 buffers the vibration during the lifting process. When the device bracket 11 rises and falls, it drives the round rod 12 and the moving frame 13 to move synchronously. The moving frame 13 can rotate around the round rod 12 to adjust the angle, and the rotation position is fixed by the positioning bolt 18 and the positioning screw hole 19. When the mounting plate 14 moves with the moving frame 13, it drives the first arc plate 16 and the second arc plate 17 to form an adjustable protective cover. By adjusting the position of the two arc plates, different arc plates can be used for protection according to the usage environment. The arc plates can also be disassembled by the mounting bolt 15 for easy maintenance and replacement. During galvanizing operations, physical isolation prevents oxidation splashing.

[0028] Furthermore, dynamic protection is achieved through an adjustable protective structure. The arc plate assembly can be adjusted and modularly replaced according to processing requirements. The hydraulic drive system, in conjunction with the spring buffer mechanism, enables smooth lifting and lowering, effectively absorbing mechanical vibrations during operation. The rotary locking mechanism uses bolts and screw holes to fix different arc plates, adapting to different usage scenarios. The modular arc plate design simplifies the maintenance process and facilitates the replacement of protective components for different working conditions. Physical isolation prevents zinc molten metal from splashing, reducing raw material waste and oxidation risks. This solves the problems of arc plates being difficult to replace and the fixed curvature arc plates being unable to fit tightly to the tail of steel pipes of different diameters, resulting in poor equipment adaptability, high maintenance costs, and low production efficiency.
