[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.

[0025] Example

[0026] A roller-type angle steel galvanizing device comprises a galvanizing tank 1 and a drying chamber 18 located at the rear end of the galvanizing tank 1, the drying chamber 18 dries the galvanized angle steel, guide rails 8 extending into the drying chamber 18 are provided on both sides of the galvanizing tank 1, two bases 9 are slidably connected to each guide rail 8, a hydraulic cylinder 10 is fixed to the base 9, a column 12 is connected to the telescopic end of the hydraulic cylinder 10, and a support rod 15 is connected to the top of the two columns 12 on the same guide rail 8, a material cage 14 for accommodating the angle steel is provided above the galvanizing tank 1, rotating shafts 13 at both ends of the material cage 14 are rotatably connected to the corresponding support rods 15, a driving component for driving the material cage 14 to rotate is provided on the base 9, and the hydraulic cylinder 10 is telescopic so that the lower end of the material cage 14 is immersed in the zinc melt in the galvanizing tank 1.

[0027] In this embodiment, Figure 1As shown, the galvanizing tank 1 is used to contain the molten zinc. The angle steel is galvanized in this tank, that is, the surface is covered with a layer of zinc to improve its anti-corrosion performance. The drying chamber 18 is located at the rear end of the galvanizing tank 1 and is used to dry the galvanized angle steel. After the galvanizing is completed, the angle steel needs to be dried quickly to prevent the zinc layer from being damaged or causing other quality problems. The guide rails 8 are arranged on both sides of the galvanizing tank 1 and extend into the drying chamber 18. The guide rails 8 provide a sliding path for the base 9 so that the material cage 14 can move smoothly between the galvanizing tank 1 and the drying chamber 18. The base 9 is slidably connected to the guide rails 8 to support and move the entire galvanizing system. A hydraulic cylinder 10 is fixed to each base 9 to control the lifting and lowering of the material cage 14. The hydraulic cylinder 10 is installed on the base 9, and its telescopic end is connected to the column 12. The lifting and lowering of the material cage 14 can be controlled by the extension and retraction of the hydraulic cylinder 10, as shown in FIG. Figure 2 As shown, the lower end of the material cage 14 can be immersed in the zinc melt in the galvanizing tank 1. The sides of the material cage 14 are grid-shaped. A feed port is provided on the side wall of the material cage 14 to allow the angle steel to be placed. After the angle steel is placed in the material cage 14, the feed port needs to be sealed. A grid-shaped baffle can be installed to prevent the angle steel from falling out when the material cage 14 rotates. The column 12 is connected to the telescopic end of the hydraulic cylinder 10 and supports the support rod 15. The two columns 12 on the same guide rail 8 jointly support a support rod 15 to ensure the stability of the material cage 14. The support rod 15 is connected to the top of the two columns 12. The part is used to support the material cage 14. The rotating shafts 13 at both ends of the material cage 14 are rotatably connected with the support rod 15, so that the material cage 14 can rotate around the support rod 15. The material cage 14 is used to load the angle steel. The rotating shafts 13 at both ends are rotatably connected with the support rod 15. In this way, the material cage 14 can rotate under the drive of the driving component, so that the angle steel can be uniformly galvanized in the galvanizing tank 1. The driving component is installed on the base 9, and is used to drive the material cage 14 to rotate. The driving component can control the rotation speed and direction of the material cage 14 to ensure the uniformity of the angle steel during the galvanizing process. Specific working principle: After the angle steel is placed in the material cage 14, the material cage 14 is lowered into the galvanizing tank 1 through the extension and contraction of the hydraulic cylinder 10, so that the angle steel is immersed in the zinc melt. Under the drive of the drive component, the material cage 14 rotates to make the angle steel uniformly galvanized. After the galvanizing is completed, the hydraulic cylinder 10 is extended again to lift the material cage 14 into the drying chamber 18 for drying. This drum-type angle steel galvanizing device has the advantages of high degree of automation, good galvanizing uniformity, and high production efficiency. It is widely used in the galvanizing production of angle steel. At the same time, when the material cage 14 rotates, the angle steels can rub against each other, thereby removing the burrs at the cutting position.

[0028] Furthermore, the driving assembly includes a motor 5, a driving gear 6, and a driven gear 3. The driving gear 6 is arranged at the output end of the motor 5, the driven gear 3 is arranged at the end of a rotating shaft 13, the driving gear 6 is located below the driven gear 3, and a transmission chain 4 is provided between the driving gear 6 and the driven gear 3.

[0029] Specifically, Figure 2 As shown, the motor 5 is used as the source of driving force. The motor 5 provides rotational power through its output end. The rotation speed and direction of the motor 5 can be accurately adjusted by the control system to meet the specific requirements of the rotation of the angle steel during the galvanizing process. The driving gear 6 is arranged at the output end of the motor 5 and is directly connected to the motor 5. When the motor 5 starts and rotates, the driving gear 6 also rotates. The number of teeth of the driving gear 6 and the speed of the output shaft of the motor 5 jointly determine the rotation speed and torque of the gear, thereby affecting the rotation speed and force of the material cage 14. The driven gear 3 is arranged at the end of the rotating shaft 13 of the material cage 14, opposite to the driving gear 6, and the driven gear 3 is arranged at the end of the rotating shaft 13 of the material cage 14. The rotation of the gear 3 will drive the rotation of the entire material cage 14. In order to ensure effective power transmission, the number of teeth of the driven gear 3 needs to match the driving gear 6, and the transmission ratio between the two needs to be accurately calculated according to actual needs. A transmission chain 4 is provided between the driving gear 6 and the driven gear 3 to transmit the rotational power of the driving gear 6 to the driven gear 3. The transmission chain 4 has high strength and wear resistance, can withstand large tension and torque, and ensure the reliability and stability of power transmission. At the same time, the chain transmission also allows a certain distance between the driving gear 6 and the driven gear 3, making the layout of the entire drive assembly more flexible. During operation, the motor 5 starts and drives the driving gear 6 to rotate. Through the action of the transmission chain 4, the rotational power of the driving gear 6 is transmitted to the driven gear 3, so that the driven gear 3 rotates accordingly. Since the driven gear 3 is connected to the rotating shaft 13 of the material cage 14, the rotation of the driven gear 3 will drive the rotation of the entire material cage 14. In this way, the drive assembly realizes the drive and control of the material cage 14, so that it rotates evenly in the galvanizing tank 1, and completes the galvanizing process of the angle steel. This drive component design has the advantages of simple structure, reliable operation, and easy maintenance. It is suitable for occasions such as drum-type angle steel galvanizing devices that require precise control of rotation speed and direction. At the same time, by adjusting the speed of the motor 5 and the transmission ratio of the gear, the rotation speed and torque of the material cage 14 can be easily adjusted to meet the galvanizing requirements of angle steels of different specifications and materials.

[0030] Furthermore, the number of teeth of the driving gear 6 is smaller than the number of teeth of the driven gear 3 .

[0031] Specifically, Figure 2As shown, the number of teeth of the driving gear 6 is less than that of the driven gear 3, that is, when the driving gear 6 rotates one circle, the number of circles of the driven gear 3 will be less than one circle. This design actually plays a role of deceleration. During the galvanizing process, a slower rotation speed is required to ensure that the angle steel can be evenly and fully contacted with the zinc melt, and to avoid the splashing of the zinc melt. By decelerating, the rotation speed of the material cage 14 can be better controlled to meet the requirements of the galvanizing process. When the number of teeth of the driving gear 6 is less than that of the driven gear 3, the output torque will increase, so that the driven gear 3 can generate greater power when rotating, thereby ensuring that the material cage 14 and the angle steel therein can rotate stably and have enough power to overcome possible resistance. Moreover, due to the use of gears and chain transmission, this driving method has higher stability and reliability. The meshing of the gears and the transmission of the chain can ensure the continuity and stability of power transmission, reducing the problems caused by unstable rotation or power interruption. In summary, the design in which the number of teeth of the driving gear 6 is smaller than the number of teeth of the driven gear 3 plays a role in reducing speed and increasing torque in the driving assembly of the roller-type angle steel galvanizing device, which helps to improve the uniformity and efficiency of the galvanizing process while ensuring the stability and reliability of the drive.

[0032] Furthermore, a bearing 16 is sleeved on the rotating shaft 13 , and the bearing 16 is embedded in the supporting rod 15 .

[0033] Specifically, Figure 1As shown, the main function of the bearing 16 is to support and reduce the friction of the rotating shaft 13 during rotation. By sleeve-arranging the bearing 16 on the rotating shaft 13, it can ensure that the material cage 14 is more stable during the rotation process, reduce the resistance caused by friction, and thus improve the stability and efficiency of the rotation. The design of the bearing 16 can reduce the direct contact between the rotating shaft 13 and the support rod 15, and reduce the wear between the two. This can not only extend the service life of the rotating shaft 13 and the support rod 15, but also reduce the maintenance cost and replacement frequency caused by wear. The bearing 16 is embedded in the support rod 15, making the entire structure more compact, and also facilitating the installation and adjustment process. During installation, it is only necessary to embed the bearing 16 into the support rod 15, and then pass the rotating shaft 13 through the bearing 16. If the position or angle of the material cage 14 needs to be adjusted, it can also be achieved by adjusting the relative position of the bearing 16 and the support rod 15. The bearing 16 is usually made of high-strength material and can withstand greater pressure and load. Therefore, by sleeve-mounting the bearing 16, the bearing capacity of the rotating shaft 13 and the support rod 15 can be improved, so that the entire drive assembly can withstand heavier material cages 14 and angle steels. In summary, the design of sleeve-mounting the bearing 16 on the rotating shaft 13 and embedding it inside the support rod 15 improves the rotation stability of the drive assembly of the roller-type angle steel galvanizing device, reduces wear, facilitates installation and adjustment, and improves the bearing capacity. This design helps to ensure the smooth rotation of the material cage 14 during the galvanizing process and improves the quality and efficiency of galvanizing.

[0034] Furthermore, a grooved guide wheel 7 is rotatably connected to the bottom surface of the base 9 , and the guide rail 8 is adapted to the grooved guide wheel 7 .

[0035] Specifically, Figure 2 As shown, the adaptive design of the grooved guide wheel 7 and the guide rail 8 ensures the smooth sliding of the base 9 on the guide rail 8. The shape of the grooved guide wheel 7 matches the cross-section of the guide rail 8, so that during the movement, the guide wheel can slide stably along the guide rail 8, reducing friction and vibration, and improving the stability and reliability of the entire device. The grooved guide wheel 7 is usually made of wear-resistant, high-strength materials and can withstand greater pressure and load. This design enables the base 9 and the material cage 14, hydraulic cylinder 10 and other components connected thereto to stably bear the weight of the angle steel and maintain a stable state of motion during the galvanizing process. The close fit between the guide wheel and the guide rail 8 helps to ensure the positioning accuracy of the base 9 during the movement, which is crucial for the accurate position adjustment of the material cage 14 between the galvanizing tank 1 and the drying chamber 18, ensuring that the angle steel can be galvanized according to the predetermined process path. The adaptive design of the grooved guide wheel 7 and the guide rail 8 simplifies the installation process and reduces the difficulty of installation.

[0036] Furthermore, a first heating plate 2 is provided on the side wall of the galvanizing tank 1, a heat-insulating layer 11 is provided on the outside of the galvanizing tank 1, and the side wall of the galvanizing tank 1 is made of a heat-conducting material.

[0037] Specifically, the first heating plate 2 on the side wall of the galvanizing tank 1 is mainly used to provide the heat required for galvanizing. Through the operation of the heating plate, the molten zinc in the galvanizing tank 1 can be kept at a certain temperature to ensure that the angle steel can be fully galvanized when immersed. The heating plate usually has the characteristics of rapid heating and uniform heating, and can effectively control the temperature of the molten zinc, thereby meeting the requirements of the galvanizing process. The side wall of the galvanizing tank 1 is made of heat-conducting material, which means that the side wall has good thermal conductivity. When the first heating plate 2 is working, the heat generated can be quickly and evenly transferred to the molten zinc in the galvanizing tank 1, ensuring the temperature stability and uniformity of the entire galvanizing process. The selection of heat-conducting materials not only improves the heating efficiency, but also helps to reduce energy consumption. The insulation layer 11 set on the outside of the galvanizing tank 1 is mainly used to reduce heat loss. The insulation layer 11 is usually composed of heat-insulating materials, which can effectively block the influence of the external environment on the temperature in the galvanizing tank 1 and maintain the stable temperature of the molten zinc, which can not only improve the heating efficiency and reduce energy consumption, but also extend the service life of the heating plate and reduce maintenance costs. In summary, the first heating plate 2 on the side wall of the galvanizing tank 1, the side wall made of heat-conductive material and the outer insulation layer 11 together constitute an efficient heating and insulation system, which ensures the stable temperature and uniform heating of the zinc melt during the galvanizing process, improves the quality and efficiency of galvanizing, and reduces energy consumption and maintenance costs.

[0038] Furthermore, an inlet 17 and an outlet 22 are provided on both sides of the drying cabin 18, and doors are provided at the inlet 17 and the outlet 22.

[0039] Specifically, in the roller-type angle steel galvanizing device, an inlet 17 and an outlet 22 are provided on both sides of the drying chamber 18, and hatches are installed at both openings. This design not only facilitates the entry and exit of materials (i.e., galvanized angle steel), but also optimizes the entire galvanizing and drying process to a great extent. Specifically:

[0040] Convenient material entry and exit: The setting of the inlet 17 and the outlet 22 allows the material to smoothly enter and leave the drying chamber 18. After the galvanizing is completed, the material enters the drying chamber 18 through the inlet 17 for drying, and is removed through the outlet 22 after drying. The whole process is continuous and efficient.

[0041] Function of the hatch: The hatches at the inlet 17 and the outlet 22 play a key role in controlling the entry and exit of materials and maintaining a stable environment inside the drying chamber 18. When materials enter or leave, the hatch is opened; during the drying process, the hatch remains closed to maintain the temperature and humidity conditions in the drying chamber 18 and ensure the drying effect.

[0042] Optimizing the process: By properly setting the inlet 17, outlet 22 and hatch, the galvanizing and drying processes can be made smoother, reducing the waiting time and energy loss of materials during the transfer process, thereby improving the production efficiency of the entire device.

[0043] Safety considerations: The presence of the door also increases the safety of the operation. During the drying process, the temperature inside the drying chamber 18 is high, and closing the door can prevent the operator from accidentally contacting the high-temperature surface, reducing the risk of burns, etc.

[0044] In summary, the inlet 17, outlet 22 and corresponding door design arranged on both sides of the drying chamber 18 not only facilitate the entry and exit of materials, optimize the galvanizing and drying process, but also improve the safety of operation, and are an important component of the drum-type angle steel galvanizing device.

[0045] Furthermore, a plurality of second heating plates 21 are disposed inside the drying chamber 18 .

[0046] Furthermore, an exhaust port 19 is provided at the top of the drying chamber 18 , and an air purifier 20 is connected to the exhaust port 19 .

[0047] Specifically, Figure 1 As shown, in the roller-type angle steel galvanizing device, a plurality of second heating plates 21 are provided inside the drying chamber 18. The presence of the second heating plates 21 enables the drying chamber 18 to maintain a constant, high-temperature environment suitable for drying, thereby accelerating the evaporation of water on the angle steel and improving the drying efficiency. At the same time, the provision of a plurality of second heating plates 21 ensures the uniform distribution of temperature in the drying chamber 18, avoiding problems such as incomplete drying or deformation of the angle steel due to uneven temperature. In addition, an exhaust port 19 is provided on the top of the drying chamber 18, which not only helps to discharge the water vapor generated during the drying process, prevents excessive humidity in the chamber from affecting the drying effect, but also reduces equipment corrosion problems caused by condensation of water vapor. The air purifier 20 connected to the exhaust port 19 further improves the environmental performance of the entire device. The air purifier 20 can effectively remove harmful substances that may be contained in the exhaust gas, such as tiny zinc particles or other pollutants, to ensure that the discharged gas meets environmental protection standards and reduces the potential impact on the environment. In summary, the second heating plate 21 arranged inside the drying chamber 18, the exhaust port 19 on the top and the air purifier 20 together constitute an efficient and environmentally friendly drying system, which can not only ensure the sufficient drying of the angle steel after galvanizing, improve product quality and production efficiency, but also effectively reduce environmental pollution in the production process, reflecting the advanced and practical design of the device.

[0048] Furthermore, one end of the guide rail 8 extends to the outside of the drying chamber 18 .

[0049] Specifically, Figure 1As shown, the design of the guide rail 8 allows the material cage 14 to be seamlessly transferred between the galvanizing tank 1 and the drying chamber 18. After the material cage 14 completes the galvanizing process in the galvanizing tank 1, it can be smoothly moved along the guide rail 8 to the drying chamber 18 for subsequent drying treatment. This continuous material transmission reduces the pause and waiting time in the operation and improves the overall production efficiency. The extension of the guide rail 8 makes the layout between the galvanizing tank 1 and the drying chamber 18 more compact and reasonable. This design optimizes the space occupied by the equipment, improves the space utilization rate, and makes the entire device more adaptable to different production environments and site conditions. In summary, the design of extending one end of the guide rail 8 to the outside of the drying chamber 18 not only ensures the continuity of material transmission and simplifies the operation process, but also optimizes the equipment layout and space utilization. This design is of great significance for improving the production efficiency and operation convenience of the roller-type angle steel galvanizing device.

[0050] 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.
