Description

Technical Field

[0001] This utility model relates to the field of galvanizing technology, and in particular to a hot-dip galvanizing device for iron accessories. Background Technology

[0002] Hot-dip galvanizing is an effective metal corrosion protection process. By immersing metal products such as steel into molten zinc, a dense and strongly adhered zinc layer is formed on its surface, which can effectively isolate the metal substrate from external corrosive media, thereby extending the service life of metal products.

[0003] However, current hot-dip galvanizing equipment has some shortcomings in practical applications: different sizes of iron accessories have different requirements for the spacing of the hangers, but the existing hanger spacing is fixed and cannot adapt to diverse size needs. When larger iron accessories are forcibly hung, the distance between two adjacent iron accessories is too small, and they are prone to collision with each other during the galvanizing process with slight shaking, resulting in uneven distribution of the galvanized layer, and even serious quality problems such as galvanized layer peeling and damage. Therefore, a hot-dip galvanizing device for iron accessories is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hot-dip galvanizing device for iron accessories.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hot-dip galvanizing device for iron accessories, comprising galvanizing equipment and a hanger, wherein the hanger is provided with multiple hooks for hanging iron accessories; and further comprising an adjusting structure disposed within the hanger, wherein the adjusting structure comprises a motor and a lead screw, wherein when the motor drives the lead screw to rotate, multiple adjacent slides move relative to each other to adjust the distance between the iron accessories suspended on the slides.

[0006] As a further description of the above technical solution: the adjustable structure includes a fixed frame and a side shell. A motor is fixedly connected to the side shell. A slide rod corresponding to the number of multiple lead screws is fixedly connected to the frame. Multiple sets of threaded grooves are opened on the slide rod. One end of the slide block is threadedly connected to the lead screw, and the other end of the slide block is slidably connected to the slide rod. The multiple sets of threaded grooves include positive threaded grooves and negative threaded grooves to allow two adjacent slide blocks to move relative to each other. Multiple partitions are fixedly connected inside the frame, and the partitions are located between two adjacent slide blocks. A protective plate is fixed to the bottom of the frame by bolts. The protective plate has slots corresponding to the number of multiple slide blocks.

[0007] As a further description of the above technical solution: a fixing plate is fixedly connected to the side wall of the slide block, the fixing plate has a through hole adapted to the size of the hook, and a fastening bolt is threadedly connected to the fixing plate. The inner end of the fastening bolt passes through the through hole and abuts against the hook.

[0008] As a further description of the above technical solution: multiple lead screws all penetrate into the side housing, and a second gear is fixedly connected to the lead screw located in the side housing. Multiple rotating rods are fixedly connected in the side housing, and the multiple rotating rods are located between the multiple lead screws. A first gear meshing with the second gear is rotatably connected to the multiple rotating rods. The motor output end is fixed to one of the first gears. The size of the first gear is smaller than the size of the second gear to increase the torque of the lead screws and make the multiple lead screws rotate in the same direction.

[0009] This utility model has the following beneficial effects:

[0010] 1. Compared with the existing technology, this hot-dip galvanizing device for iron accessories, by setting an adjustable spacing structure, a motor-driven lead screw with positive and negative thread groove design, and multiple slides that can move relative to each other, can achieve precise adjustment of the spacing of iron accessories, and can be adapted to a variety of iron accessories of different specifications. Compared with traditional fixed spacing hangers, it improves the versatility and flexibility of the device.

[0011] 2. Compared with the existing technology, this hot-dip galvanizing device for iron accessories adopts a gear transmission method. The first gear is smaller than the second gear and is cleverly arranged between adjacent second gears. This not only increases the torque of the lead screw, but also enables multiple lead screws to rotate in the same direction, improving the reliability and stability of the device operation and ensuring the accuracy and efficiency of the adjustment process.

[0012] 3. Compared with the existing technology, this hot-dip galvanizing device for iron accessories makes the hanging and picking of iron accessories more convenient by setting hooks and slides. At the same time, the fastening bolts and the anti-slip texture on the hooks are in close contact to ensure that the iron accessories are stably suspended during the galvanizing process. The installation height of the hooks can also be adjusted to further improve flexibility. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-6 This utility model provides a hot-dip galvanizing device for iron accessories: it includes a galvanizing equipment 1 and a hanger 2. It is known that the hanger 2 is the hoisting mechanism in the galvanizing equipment 1, and the galvanizing equipment 1 is prior art, so it will not be described in detail hereafter. The hanger 2 is provided with multiple hooks 3 for hanging iron accessories; it also includes an adjustable distance structure, which is set in the hanger 2. The adjustable distance structure includes a motor 6 and a lead screw 10. When the motor 6 drives the lead screw 10 to rotate, it causes multiple adjacent slides 12 to move relative to each other, so as to adjust the distance between the iron accessories suspended on the slides 12.

[0023] The adjustable spacing structure includes a fixed frame 4 and a side shell 5. A motor 6 is fixedly connected to the side shell 5. A slide rod 11 corresponding to the number of lead screws 10 is fixedly connected to the frame 4. The slide rod 11 has multiple sets of threaded grooves. One end of the slide block 12 is threadedly connected to the lead screw 10, and the other end of the slide block 12 is slidably connected to the slide rod 11. The multiple sets of threaded grooves include positive threaded grooves and negative threaded grooves to allow relative movement between adjacent slide blocks 12. The maximum distance between the slide blocks 12 is 200mm. The adjustable spacing structure is embedded inside the hanger. The motor 6 and the lead screw 10 are tightly engaged. When the motor 6 is running, the lead screw 10 begins to rotate and move. It should be noted that a low-speed motor of 10~50 rpm is used. The slide blocks 12 achieve relative displacement under the guidance of the positive and negative threaded grooves. The distance between the hooks 3 on them changes accordingly. The slide rod 11 is designed with multiple sets of threaded grooves to provide a track for the movement of the slide blocks 12, so that each slide block 12 can move and maintain the consistency of the distance, thereby realizing the adjustment of the distance of the iron accessories.

[0024] Multiple partitions 15 are fixedly connected inside the frame 4, and the partitions 15 are located between two adjacent slides 12. The distance between two adjacent partitions 15 is 200mm. The slides 12 slide in this space, which can accommodate most small iron accessories ≥50mm and large iron accessories ≥150mm. A protective plate 16 is fixed to the bottom of the frame 4 by bolts. The protective plate 16 has slots 17 corresponding to the number of multiple slides 12.

[0025] A fixing plate 13 is fixedly connected to the side wall of the slide 12. The fixing plate 13 has a through hole that matches the size of the hook 3. A fastening bolt 14 is threaded to the outer end of the fixing plate 13. The inner end of the fastening bolt 14 passes through the through hole. Since the fastening bolt 14 is located on the side wall of the hook 3, the inner end of the fastening bolt 14 abuts against the side wall of the hook 3. In addition, the rod of the hook 3 is provided with anti-slip texture. During the fastening process, the fastening bolt 14 is rotated, and the clamping force is generated by the thread to fix the hook 3 on the slide 12. This prevents the hook 3 from loosening during the galvanizing process and ensures that the iron accessory can be stably suspended on the hanger 2. The height of the hook 3 can be adjusted in this way.

[0026] Multiple lead screws 10 extend into the side housing 5, and a second gear 9 is fixedly connected to each lead screw 10 located within the side housing 5. Multiple rotating rods 7 are fixedly connected within the side housing 5, located between the multiple lead screws 10, and a first gear 8 meshing with the second gear 9 is rotatably connected to each of the multiple rotating rods 7. The output end of the motor 6 is fixed to one of the first gears 8. The size of the first gear 8 is smaller than that of the second gear 9 to increase the torque of the lead screws 10 and to make the multiple lead screws 10 rotate in the same direction. For example, the diameter of the first gear 8 can be set to 1 / 2 or smaller than the diameter of the second gear 9. During power transmission, the output torque of the lead screws 10 can be increased through the deceleration effect of the gears.

[0027] Working principle: First, the iron accessories to be galvanized are hung one by one on the hooks 3 of the hanger 2. Then, the motor 6 is started. The output shaft of the motor 6 drives the first gear 8 fixed thereto to rotate. The first gear 8 meshes tightly with the second gear 9, thereby driving the second gear 9 to rotate accordingly.

[0028] When the lead screw 10 rotates, the end threadedly connected to the slide 12 begins to move. At the same time, the other end of the slide 12 slides along the slide rod 11. The positive and negative threaded grooves on the slide rod 11 guide the movement direction of the slide 12, so that multiple adjacent slides 12 achieve relative displacement under the rotation of the lead screw 10. Adjust the distance between them, observe the current distance between the iron accessories, and stop the displacement when the distance is appropriate. The specific distance is set according to the actual processing requirements of the iron accessories, which will not be elaborated here.

[0029] After adjustment, the slot 17 of the protective plate 16 provides a moving channel for the slide 12, while blocking external interference and ensuring the stable operation of the adjustable spacing structure. All components return to a stable state. At this time, the hanger 2 carrying the iron accessories is immersed in the zinc plating liquid of the zinc plating equipment 1. The zinc plating liquid evenly covers the surface of the iron accessories. Thanks to the pre-adjusted matching spacing of the adjustable spacing structure, the iron accessories do not interfere with each other, and the zinc plating liquid can flow fully, making the zinc plating process efficient and uniform.

[0030] After galvanizing is completed, the operator drives motor 6 to reverse motor 6 or manually resets the pitch adjustment structure to restore the spacing of slide block 12 to its initial state, preparing for the galvanizing operation of the next batch of iron accessories. At this point, the device completes one work cycle and can be put back into use for the next round of efficient galvanizing operations.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
