Description

Technical Field

[0001] The utility model relates to the technical field of galvanizing angle steel for power iron towers, in particular to a galvanizing device for angle steel for power iron towers. Background Art

[0002] In the production of steel pipe towers, angle steel is an indispensable material. In order to make the angle steel have a longer service life, the angle steel needs to be galvanized. Galvanized angle steel is divided into hot-dip galvanized angle steel and cold-dip galvanized angle steel. Hot-dip galvanized angle steel is also called hot-dip galvanized angle steel or hot-dip galvanized angle steel. Cold-dip galvanizing paint mainly uses electrochemical principles to ensure full contact between zinc powder and steel, generating electrode potential difference for corrosion protection.

[0003] Hot-dip galvanizing is commonly used. Generally, the angle steel is placed in a mesh box and then the mesh box is immersed in molten zinc. However, the angle steels are stacked and contacted with each other, making it difficult for the contact parts between the angle steels to contact with the molten zinc, resulting in incomplete galvanizing of the angle steel and poor quality. Utility Model Content

[0004] The utility model aims to provide an angle steel galvanizing device for power iron towers, which can effectively carry out comprehensive galvanizing on the angle steels, ensure that each angle steel can be coated with zinc melt, and improve the quality of galvanizing of the angle steels.

[0005] In order to solve the above technical problems, the utility model adopts the following solutions:

[0026] Example

[0027] An angle steel galvanizing device for power towers comprises a galvanizing cabin 1, a galvanizing pool 17 filled with molten zinc is installed in the galvanizing cabin 1, an electric hoist 10 is arranged on the top of the galvanizing cabin 1, a chain 9 of the electric hoist 10 is connected to a mesh box 11, the mesh box 11 is located directly above the galvanizing pool 17, the mesh box 11 contains angle steel to be galvanized, the electric hoist 10 controls the mesh box 11 to move down into the galvanizing pool 17 so that the angle steel is immersed in the molten zinc, a transmission part is arranged on the mesh box 11, a driving part is arranged on the inner side wall of the galvanizing cabin 1, after the mesh box 11 is lowered into the galvanizing pool 17, the transmission part cooperates with the driving part, and the driving part drives the mesh box 11 to move back and forth so that the angle steel is fully in contact with the molten zinc.

[0028] In this embodiment, Figure 1 As shown, the main purpose of the device is to galvanize the angle steel. The main components of the device include a galvanizing cabin 1, a galvanizing pool 17, an electric hoist 10, a mesh box 11, transmission parts and drive parts. First, the galvanizing cabin 1 is the main place for galvanizing operations. A galvanizing pool 17 filled with molten zinc is installed inside. The molten zinc is necessary in the galvanizing process. It can cover the surface of the angle steel with a layer of zinc, thereby playing a role in corrosion and rust prevention. The electric hoist 10 is located on the top of the galvanizing cabin 1 and is connected to the mesh box 11 through a chain 9. The mesh box 11 is used to load the angle steel to be galvanized. Figure 2As shown, when the electric hoist 10 controls the mesh box 11 to move down into the galvanizing pool 17, the angle steel will be immersed in the zinc melt, thereby starting the galvanizing process. In addition, a transmission part is provided on the mesh box 11, and a driving part is provided on the inner wall of the galvanizing chamber 1. When the mesh box 11 is lowered into the galvanizing pool 17, the transmission part and the driving part will work together, and the driving part will drive the mesh box 11 to move back and forth in the galvanizing pool 17, so that the angle steels that are in contact with each other can be separated, so that all parts of the angle steel can be fully in contact with the zinc melt, ensuring the uniformity and integrity of the galvanizing. This angle steel galvanizing device for power towers realizes automatic galvanizing of the angle steel through the cooperation of the electric hoist 10, the mesh box 11, the transmission part and the driving part, thereby improving the work efficiency and the galvanizing quality.

[0029] Furthermore, the driving member is a driving motor 18, which is located above the galvanizing pool 17. A gear 3 is provided at the output end of the driving motor 18. The transmission member is a rack 4, and the teeth of the rack 4 face downward. The rack 4 is connected to a fixing plate 5 by bolts. The fixing plate 5 is fixed to the side wall of the mesh box 11. After the mesh box 11 is lowered into the galvanizing pool 17, the gear 3 is meshed with the rack 4.

[0030] Specifically, Figure 1 As shown, the driving member is embodied as a driving motor 18, which is located above the galvanizing pool 17. The output end of the driving motor 18 is provided with a gear 3, and the power is transmitted by the rotation of the gear 3. The transmission member is embodied as a rack 4, and the teeth of the rack 4 face downward. The rack 4 is connected to the fixing plate 5 by bolts, and the fixing plate 5 is fixed to the side wall of the net box 11. When the net box 11 descends into the galvanizing pool 17, the rack 4 can descend with the net box 11 and mesh with the gear 3 of the driving motor 18. Once the gear 3 meshes with the rack 4, the driving motor 18 can drive the rack 4 to reciprocate through the gear 3. Since the rack 4 is connected to the net box 11 through the fixing plate 5, this reciprocating movement will drive the net box 11 to move accordingly in the galvanizing pool 17. In this way, the position of the angle steel in the zinc melt will change continuously, thereby ensuring that the angle steel and the zinc melt can fully contact and achieve uniform galvanizing. Through the cooperation of the driving motor 18, the gear 3, the rack 4 and the fixing plate 5, the angle steel galvanizing device for the power tower can realize the automatic reciprocating movement of the grid box 11 and the angle steel therein, thereby improving the galvanizing effect and efficiency.

[0031] Furthermore, the rack 4 is located outside the mesh box 11 .

[0032] Furthermore, the height of the mesh box 11 is greater than the depth of the galvanizing pool 17 .

[0033] Specifically, the rack 4 is arranged on the outside of the mesh box 11, which helps the rack 4 to smoothly mesh with the gear 3 of the drive motor 18 located above the galvanizing pool 17 during the descent of the mesh box 11. Since the rack 4 is located on the outside of the mesh box 11, it will not be affected by the zinc melt or the angle steel in the mesh box 11, thereby ensuring the stability and reliability of the transmission. At the same time, considering that the mesh box 11 needs to be completely immersed in the zinc melt to galvanize the angle steel, the height of the mesh box 11 is designed to be greater than the depth of the galvanizing pool 17. Such a design ensures that the mesh box 11 can completely enter the galvanizing pool 17 during the descent process, and the angle steel can be completely immersed in the zinc melt. The height of the mesh box 11 being greater than the depth of the galvanizing pool 17 also means that even if the zinc melt fluctuates during the galvanizing process, the mesh box 11 can still maintain a stable immersed state, thereby ensuring the smooth progress of the galvanizing process.

[0034] Furthermore, a hook is provided at the lower end of the chain 9 of the electric hoist 10, and steel wire ropes 8 are provided at the four corners of the top of the net box 11. The top ends of the four steel wire ropes 8 are connected to lifting rings, and the lifting rings are hung on the hooks.

[0035] Specifically, Figure 2 As shown, the lower end of the chain 9 of the electric hoist 10 is provided with a hook for connecting and hanging heavy objects. In this galvanizing device, the main function of the hook is to connect and support the net box 11. The four corners of the top of the net box 11 are provided with steel wire ropes 8. This design is to ensure the stability and safety of the net box 11 during the hanging and moving process. The four steel wire ropes 8 are respectively located at the four corners of the net box 11, which can evenly disperse the weight of the net box 11 and prevent it from tilting or shaking during the movement. The tops of the four steel wire ropes 8 are connected to the lifting ring, which is a ring structure for concentrating and fixing the steel wire ropes 8. The design of the lifting ring allows multiple steel wire ropes 8 to be easily connected together to form a stable suspension system. Finally, the lifting ring is hung on the hook of the electric hoist 10, so that the electric hoist 10 can achieve the hanging and moving of the net box 11 through the combination of the chain 9, the hook, the lifting ring and the steel wire rope 8. When the electric hoist 10 is working, it can lift the mesh box 11 by controlling the length of the chain 9, so that the mesh box 11 and the angle steel therein can be easily immersed in or taken out of the zinc melt. The hook of the electric hoist 10, the steel wire rope 8 and the lifting ring of the mesh box 11 together form a stable and reliable suspension system, so that the mesh box 11 can be conveniently and safely lifted and moved in the galvanizing cabin 1, thereby achieving galvanizing treatment of the angle steel.

[0036] Furthermore, a glass observation window 19 is provided on the front side wall of the galvanizing cabin 1 .

[0037] Specifically, Figure 3As shown, the glass observation window 19 provides an intuitive window for the operator to observe the galvanizing process. Through this observation window, the operator can clearly see the position of the mesh box 11 in the zinc melt, the galvanizing condition of the angle steel, and the state of the zinc melt, etc. Such observation helps the operator to understand the galvanizing process in time and judge whether it is necessary to adjust the galvanizing parameters or perform other operations. Secondly, the existence of the glass observation window 19 enhances the safety of the galvanizing process. Since the galvanizing process involves the operation of high-temperature zinc melt and electric equipment, the operator should not directly contact the inside of the galvanizing cabin 1. Through the observation window, the operator can monitor the galvanizing process in real time without entering the galvanizing cabin 1, reducing the operating risk. In addition, the glass observation window 19 is also convenient for troubleshooting and maintenance of the galvanizing device. If an abnormal situation occurs during the galvanizing process, the operator can quickly locate the problem through the observation window and take corresponding measures to repair or adjust it in time. The glass observation window 19 set on the front side wall of the galvanizing cabin 1 not only improves the visualization of the galvanizing process and enhances the safety of operation, but also helps troubleshooting and maintenance. This design fully reflects the humanization and efficiency of the galvanizing device. At the same time, an entry and exit door can be set on the side of the glass observation window 19 to facilitate workers to enter and exit the galvanizing cabin 1.

[0038] Furthermore, a through hole 12 is provided on the side wall of the galvanizing chamber 1, a heating pipe 13 is connected to the through hole 12, a blower 16 is connected to the end of the heating pipe 13, a heating box 14 is provided on the heating pipe 13 between the blower 16 and the galvanizing chamber 1, and a heating plate 15 is provided in the heating box 14.

[0039] Furthermore, an exhaust port 7 is provided at the top of the galvanizing cabin 1 , and an exhaust fan 6 is provided at the exhaust port 7 .

[0040] Specifically, Figure 1 As shown, in the galvanizing device, the through hole 12 arranged on the side wall of the galvanizing chamber 1 and the heating pipe 13, the blower 16 and the heating box 14 connected thereto constitute an effective heating and ventilation system. Specifically, the blower 16 blows hot air into the galvanizing chamber 1 through the heating pipe 13, and a heating box 14 is arranged on the heating pipe 13 between the blower 16 and the galvanizing chamber 1, and a heating plate 15 is arranged in the heating box 14. When the blower 16 is working, the air is heated by passing through the heating box 14, and then blown into the galvanizing chamber 1 through the heating pipe 13, so that hot air can be effectively blown to the galvanized angle steel to dry it and improve the efficiency of galvanizing. In addition, the exhaust port 7 and the exhaust fan 6 arranged on the top of the galvanizing cabin 1 play a role in regulating the air circulation in the galvanizing cabin 1 and removing the exhaust gas. During the galvanizing process, some harmful gases may be generated in the galvanizing cabin 1 due to heating and chemical reactions. The exhaust fan 6 discharges these exhaust gases through the exhaust port 7 to keep the air in the galvanizing cabin 1 fresh. The exhausted exhaust gas cannot be discharged directly, and needs to enter a specific air purifier before being discharged to avoid polluting the environment.

[0041] Furthermore, a heat-insulating layer 2 is sandwiched in the side wall of the galvanized cabin 1.

[0042] Specifically, Figure 1 As shown, the purpose of the insulation layer 2 sandwiched in the side wall of the galvanizing tank 1 is to improve the insulation performance of the galvanizing tank 1. Specifically, the insulation layer 2 can reduce the heat loss inside the galvanizing tank 1, thereby maintaining the temperature stability of the zinc melt and the drying efficiency of the angle steel after galvanizing. During the galvanizing process, the zinc melt needs to maintain a certain temperature to effectively galvanize the angle steel, and the presence of the insulation layer 2 can effectively prevent heat from being lost to the external environment through the side wall of the galvanizing tank 1. In addition, the insulation layer 2 can also reduce the impact of the external temperature of the galvanizing tank 1 on the internal working environment. Under extreme weather conditions, such as high or low temperature environments, the insulation layer 2 can help maintain the relative stability of the internal temperature of the galvanizing tank 1, ensuring the continuity and stability of the galvanizing work.

[0043] Furthermore, the mesh box 11 has an open top, and the circumferential side surfaces and the bottom surface are all in a mesh shape.

[0044] Specifically, the design of the top opening of the net box 11 allows the angle steel to be easily put in or taken out, and also allows the zinc melt to smoothly enter the inside of the net box 11 during the galvanizing process, and perform a full range of galvanizing treatment on the angle steel. This design not only ensures the convenience of operation, but also ensures the uniformity and integrity of the galvanizing. The circumferential side and bottom surfaces of the net box 11 are designed to be grid-shaped. This structure allows the zinc melt to freely penetrate the net box 11 and fully contact the angle steel in the net box 11. The grid-shaped design increases the contact area between the angle steel and the zinc melt, and improves the galvanizing effect. At the same time, the grid-shaped structure can also effectively prevent the angle steels from sticking to or stacking each other during the galvanizing process, ensuring that each angle steel can be fully galvanized. In summary, the top opening of the net box 11 and the grid-shaped design of the circumferential side and bottom surfaces not only facilitate the placement and removal of the angle steel, improve the convenience of operation, but also ensure that the angle steel is fully in contact with the zinc melt during the galvanizing process, and improve the galvanizing effect and quality. This design fully considers the actual needs of the galvanizing process and reflects the practicality and efficiency of the device.

[0045] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
