Description

Technical Field

[0001] This utility model relates to the technical field of steel component manufacturing and processing, specifically to a cooling spraying device for hot-dip galvanizing steel components for power transmission towers. Background Technology

[0002] In the construction of power transmission towers, hot-dip galvanizing of steel components is a crucial anti-corrosion method. Hot-dip galvanized steel components effectively resist environmental corrosion and extend the service life of the transmission towers. Hot-dip galvanizing involves immersing rust-removed steel components in molten zinc at approximately 500°C, causing a zinc layer to adhere to the surface of the steel components. After hot-dip galvanizing, the cooling process is critical. Traditional cooling methods often involve directly placing the galvanized steel components into a flowing water cooling tank. While convenient, this method has several drawbacks. First, the high temperature of the hot-dip galvanized steel components, combined with the buoyancy and flow of the water, easily leads to defects such as ripples and cracks in the galvanized layer, severely affecting its quality and protective effect. Second, traditional cooling tanks use flowing water directly, resulting in a huge water consumption and significant waste of water resources. Furthermore, some conventional cooling operations employ unidirectional water mist spraying, resulting in incomplete contact between the water mist and the steel components, leading to uneven cooling and adversely affecting subsequent processing. Therefore, it is urgent to develop a high-efficiency, water-saving cooling spray system for power transmission tower steel components after hot-dip galvanizing that can ensure the quality of the galvanized layer.

[0003] Application number CN202223521141.7 discloses a forging spray cooling device, which includes a movable flipping mechanism disposed within a spraying mechanism. The movable flipping mechanism includes a movable frame, on which a first support rod is rotatably mounted. One end of the first support rod is connected to a first pressure block via a first cylinder, and the other end is fixed to a second pressure block, such that the extension and retraction of the first cylinder can move the first pressure block closer to or away from the second pressure block. A second support rod is vertically mounted on the first support rod, and clamping assemblies are respectively disposed at both ends of the second support rod. The device includes a base mounted on a second support rod, a second cylinder housed within the base, and a pressing component hinged to the end of the base. The upper end of the pressing component is located above the second support rod, and its lower end is hinged to the piston rod of the second cylinder. This design solves the problem of existing cooling devices that can only spray cooling on one side of the forging, resulting in low cooling efficiency for large forgings. However, the device has shortcomings. When in use, it cannot achieve high-efficiency and wide-area cooling during the cooling spraying operation, leading to low efficiency. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4 As shown, this utility model is a cooling spraying device for hot-dip galvanized steel components of power transmission towers, including a coolant outlet assembly 1, a working plate assembly 2 fixedly installed on the top of the coolant outlet assembly 1, a rotary brake assembly 3 fixedly installed on one side of the top of the working plate assembly 2, and a height adjustment assembly 4 fixedly installed on the braking side of the rotary brake assembly 3.

[0026] The rotary braking assembly 3 includes a pneumatic telescopic rod 301, which is mounted on the top side of the mounting base plate 201 via a mounting bracket 302. A movable slider 303 is fixedly mounted at the end of the pneumatic telescopic rod 301. The movable slider 303 is slidably mounted on a limit rail 304, and a rack 305 is fixedly mounted inside the movable slider 303.

[0027] By installing a rotary brake assembly 3 on the device, numerous parts can be fixedly installed around the rotary brake assembly 3 when using the device, thereby improving the cooling efficiency.

[0028] The coolant outlet assembly 1 includes a water pump 101. A connecting bracket 102 is fixedly installed around the top periphery of the water pump 101, and a telescopic spring water outlet pipe 104 is fixedly installed in the middle of the top of the water pump 101. A connecting pipe 105 is fixedly installed on the top of the telescopic spring water outlet pipe 104, and a spray head 106 is fixedly installed on the top of the connecting pipe 105. A mounting platform 103 is fixedly installed on the top of the connecting bracket 102. During operation, the water pump 101 starts, drawing coolant from the storage location and delivering it to the spray head 106 through the telescopic spring water outlet pipe 104 and the connecting pipe 105, preparing for subsequent cooling spraying. During this process, the connecting bracket 102 is used to fix the water pump 101, and the mounting platform 103 can be used to install other auxiliary equipment or components, ensuring the stable operation of the coolant delivery system.

[0029] The working plate assembly 2 includes a mounting base plate 201. Mounting side plates 202 are fixedly mounted on both ends of one side of the mounting base plate 201. Buffer columns 203 are fixedly mounted on the inner wall of the mounting side plates 202. A movable slider 205 is correspondingly arranged between the two buffer columns 203. The movable slider 205 is slidably mounted on the top of the limiting slide rail 204. A rack 206 is fixedly mounted on the outer wall of one side of the movable slider 205. The limiting slide rail 204 is fixedly mounted on the top side of the mounting base plate 201. The movable slider 205 in the working plate assembly 2 can slide on the limiting slide rail 204. The position of the movable slider 205 can be adjusted manually or through a preset program according to the initial position of the steel part. During the adjustment process, the buffer columns 203 can play a buffering and shock-absorbing role to avoid excessive impact during movement.

[0030] Rack 2 305 and rack 1 206 are positioned opposite each other. The pneumatic telescopic rod 301 of the rotary braking assembly 3 is mounted on the mounting base plate 201 via the mounting bracket 302. The pneumatic telescopic rod 301 extends or retracts, causing the movable slider 2 303 to slide on the limiting slide rail 2 304, thereby adjusting the position of rack 2 305 so that it engages with rack 1 206, preparing for subsequent rotational adjustment. When it is necessary to adjust the spray angle, the pneumatic telescopic rod 301 continues to move, causing the movable slider 2 303 to move on the limiting slide rail 2 304, causing rack 2 305 to move linearly. Since rack 2 305 meshes with the rotating gear disk 401, and the rotating gear disk 401 meshes with rack 1 206, the linear motion of rack 2 305 is converted into the rotational motion of the rotating gear disk 401, thereby driving the height adjustment assembly 4 to rotate as a whole, realizing the adjustment of the spray angle of the spray head 106 to cover the surface of the steel part at different angles.

[0031] The height adjustment assembly 4 includes a rotating gear disk 401. Pneumatic pumps 402 are fixedly mounted on both sides of the top of the rotating gear disk 401. A lifting bracket 403 is fixedly mounted on the top of the pneumatic pumps 402. A connecting pipe 105 passes through the middle of the lifting bracket 403. Depending on the height of the steel component, the pneumatic pumps 402 in the height adjustment assembly 4 are activated. The pneumatic pumps 402 operate, pushing the lifting bracket 403 to rise or fall vertically. Since the connecting pipe 105 passes through the lifting bracket 403, it drives the spray head 106 to adjust its height, ensuring that the spray head 106 is at a suitable spray height and that the coolant can be sprayed evenly and effectively onto the surface of the steel component.

[0032] The rotating gear disk 401 is provided with rack 206 and rack 305 on both sides respectively, and the rotating gear disk 401 and rack 206 and rack 305 are all meshed with each other.

[0033] The cooling spray equipment for hot-dip galvanized steel components of the power transmission tower mainly provides coolant through the coolant outlet assembly 1. The working plate assembly 2, rotary brake assembly 3, and height adjustment assembly 4 work together to flexibly adjust the spray position and height, thereby efficiently cooling the hot-dip galvanized steel components of the power transmission tower. Specifically, the rotary brake assembly 3 and the working plate assembly 2 convert linear motion into rotational motion through the meshing of rack 1 206, rack 2 305, and rotating gear 401, thereby driving the height adjustment assembly 4 to rotate. Simultaneously, the pneumatic telescopic rod 301 and pneumatic pump 402 achieve linear movement and height adjustment to adapt to the cooling needs of steel components of different sizes and positions. During the workflow, the water pump 101 starts, drawing coolant from the storage location and delivering it to the spray head 106 through the telescopic spring outlet pipe 104 and connecting pipe 105, preparing for subsequent cooling spraying operations. During this process, the connecting bracket 102 is used to fix the water pump 101, and the mounting platform 103 can be used to install other auxiliary equipment or components to ensure the stable operation of the coolant delivery system. The movable slider 205 in the working plate assembly 2 can slide on the limiting slide rail 204. According to the initial position of the steel part, the position of the movable slider 205 can be adjusted manually or through a preset program. During the adjustment process, the buffer column 203 can play a buffering and shock-absorbing role to avoid excessive impact during movement. At the same time, the pneumatic telescopic rod 301 of the rotary brake assembly 3 is mounted on the mounting base plate 201 through the mounting bracket 302. The pneumatic telescopic rod 301 extends or retracts, driving the movable slider 303 to slide on the limiting slide rail 304, thereby adjusting the position of the rack 305 so that it cooperates with the rack 206, preparing for subsequent rotation adjustment. When it is necessary to adjust the spray angle, the pneumatic telescopic rod 301 continues to move, driving the movable slider 303 to move on the limiting slide rail 304, so that the rack 305 moves linearly. Since rack 2 305 meshes with rotating gear 401, and rotating gear 401 meshes with rack 1 206, the linear motion of rack 2 305 is converted into the rotational motion of rotating gear 401, which in turn drives the height adjustment assembly 4 to rotate as a whole, thereby adjusting the spray angle of spray head 106 to cover the surface of the steel component at different angles. Based on the height of the steel component, the pneumatic pump 402 in the height adjustment assembly 4 is activated. The pneumatic pump 402 operates, pushing the lifting bracket 403 to rise or fall vertically. Since the connecting pipe 105 passes through the lifting bracket 403, it drives the spray head 106 to adjust its height, ensuring that the spray head 106 is at a suitable spray height and that the coolant can be sprayed evenly and effectively onto the surface of the steel component. After completing the above position and angle adjustments, the spray head 106 evenly sprays the coolant onto the surface of the hot-dip galvanized steel transmission tower component, cooling the steel component.During the cooling process, the spray angle and height can be fine-tuned again using the above steps based on the actual cooling effect to achieve the best cooling result. After the cooling work is completed, turn off the water pump 101 to stop the delivery of coolant. At the same time, the pneumatic telescopic rod 301 and the pneumatic pump 402 are reset, restoring all components of the equipment to their initial positions or suitable storage locations, preparing for the next cooling operation.
