Description

Technical Field

[0001] This utility model belongs to the field of bolt oiling technology, specifically relating to a device for applying insulating coating to anchor bolts. Background Technology

[0002] In various applications, anchor bolts play a crucial role, whether in the construction industry for stabilizing large structures or in industrial equipment installations for ensuring stable operation. To meet specific usage requirements, such as in some electrical equipment installation scenarios where preventing current conduction through anchor bolts and potential safety issues, applying an insulating coating is essential.

[0003] In existing technologies, an insulating coating is typically applied to the surface of anchor bolts using a dip-coating process. However, this method struggles to ensure uniform coating coverage for anchor bolts with complex shapes. Uneven coating can lead to variations in the insulation performance of the anchor bolts. In applications with extremely high insulation requirements, weak areas in the coating may become potential points of current leakage, reducing the safety and stability of equipment operation.

[0024] Please see Figure 1The present invention provides a device for applying insulating coating to anchor bolts. The device includes a paint tank 10, a lifting frame 20, a clamping assembly 30, and a paint assembly 40. The paint tank 10 holds insulating coating 60, and its top wall has a paint inlet 11. The lifting frame 20 is mounted on the paint tank 10 and located above the paint inlet 11. A cover plate 21 is vertically slidably mounted on the lifting frame 20, and the cover plate 21 is used to slide up and down to open or close the paint inlet 11. The clamping assembly 30 is located on the bottom wall of the cover plate 21 and has multiple clamping ends for clamping the anchor bolts 70 to be coated. The paint assembly 40 is located inside the paint tank 10 and above the liquid surface of the insulating coating 60, and is used to spray the insulating coating 60 onto the anchor bolts 70.

[0025] It should be noted that multiple clamping ends of the clamping assembly 30 fix multiple anchor bolts 70 to be coated under the cover plate 21. The cover plate 21 slides downward on the lifting frame 20 and delivers the anchor bolts 70 into the coating tank 10, and the cover plate 21 can seal the coating opening 11. When the coating assembly 40 sprays insulating coating 60 onto the anchor bolts 70, the insulating coating 60 can evenly cover all parts of the complex-shaped anchor bolts 70. Because the cover plate 21 seals the coating opening 11, the insulating coating 60 cannot leak out of the coating tank 10, and at the same time, it can reduce the volatilization of volatile components in the insulating coating 60 in the coating tank 10, thereby reducing environmental pollution.

[0026] Compared with existing technologies, the anchor bolt insulation coating device provided by this utility model sprays insulating coating 60 onto the anchor bolt 70 using the coating component 40. This allows the insulating coating 60 to be more evenly covered on all parts of the complex-shaped anchor bolt 70, reducing the problem of uneven coating coverage in dip coating. This effectively avoids differences in insulation performance caused by uneven coating, improving the safety and stability of equipment operation. The lifting frame 20 is equipped with a sliding cover plate 21. During the coating process, the cover plate 21 can slide downwards along the lifting frame 20 to seal the coating opening 11, reducing the volatilization of volatile components in the coating and minimizing environmental pollution, thus meeting environmental protection requirements. The clamping component 30 can simultaneously clamp multiple anchor bolts 70 for coating operations, improving coating efficiency.

[0027] In one possible implementation, please refer to Figure 1 The lifting frame 20 is provided with a first telescopic drive component 22, which is located above the paint inlet 11 and its output end is connected to the cover plate 21.

[0028] It should be noted that the first telescopic drive component 22 can be a cylinder, a hydraulic cylinder, or an electric push rod, preferably a cylinder. The first telescopic drive component 22 drives the cover plate 21 to slide up and down, eliminating the need for manual operation, reducing manual intervention time, and making it suitable for mass production scenarios. The first telescopic drive component 22 is directly connected to the cover plate 21 and located directly above the coating opening 11, allowing precise control of the closing position of the cover plate 21. This ensures complete sealing of the coating opening 11 during the coating process, effectively reducing the volatilization of volatile components in the insulating coating 60, lowering the risk of environmental pollution, and improving coating utilization.

[0029] In some embodiments, please refer to Figure 2 The clamping assembly 30 includes multiple rotating shafts 31, a transmission structure 32, and multiple threaded tubes 33. Each rotating shaft 31 is rotatably disposed on the bottom wall of the cover plate 21 along the length direction of the cover plate 21. The transmission structure 32 is disposed on the cover plate 21 and is connected to each rotating shaft 31 for transmission. The transmission structure 32 is used to drive each rotating shaft 31 to rotate. Each threaded tube 33 is respectively disposed on each rotating shaft 31, and the inner wall of each threaded tube is provided with an internal thread that mates with the thread of the anchor bolt 70. Each threaded tube 33 forms a clamping end.

[0030] It should be noted that multiple rotating shafts 31 and threaded tubes 33 are spaced apart along the length of the cover plate 21, which can simultaneously clamp multiple anchor bolts 70, enabling a single-coat operation mode for multiple bolts, significantly improving the coating efficiency of the anchor bolts 70. The threaded tube 33 engages with the external thread of the anchor bolt 70 through its internal thread, achieving rigid clamping of the anchor bolt 70 and preventing it from falling off. The transmission structure 32 drives all rotating shafts 31 to rotate synchronously, which in turn drives the anchor bolts 70 to rotate, ensuring that the insulating coating 60 sprayed by the coating component 40 can evenly cover the bolt surface. Rotary coating can also eliminate coating thickness differences caused by gravity, resulting in a more uniform insulating film layer.

[0031] For example, please refer to Figure 2 The transmission structure 32 includes multiple sprockets 321, chains 322 and a first rotary drive 323; each sprocket 321 is respectively sleeved on each rotating shaft 31; the chain 322 is meshed with each sprocket 321; the first rotary drive 323 is disposed on the cover plate 21 and its output end is connected to one of the rotating shafts 31.

[0032] It should be noted that multiple sprockets 321 are respectively fitted onto each rotating shaft 31 and are all meshed with chains 322. The first rotary drive 323 can be a motor. When the first rotary drive 323 drives one of the rotating shafts 31 to rotate, the rotating shaft 31 drives the sprockets 321 to rotate, and drives the chains 322 to move in a circular motion around each sprocket 321. The chains 322 will drive the other sprockets 321 to rotate synchronously, so that all rotating shafts 31 can rotate at the same speed. This ensures that all anchor bolts 70 can rotate synchronously during the coating process, so that the surface of each anchor bolt 70 can be evenly sprayed with paint, ensuring the consistency of the coating quality of all anchor bolts 70. When transmitting power, the sprockets 321 and chains 322 can avoid slippage and efficiently transmit the power of the first rotary drive 323 to each rotating shaft 31, which can better meet the power requirements of the coating device and improve the overall working efficiency of the equipment.

[0033] For example, please refer to Figure 3 The coating assembly 40 includes a coating rack 41, a coating pump 42, a material extraction pipe 43, and multiple nozzles 44. The coating rack 41 is located inside the coating tank 10 and above the liquid surface of the insulating coating 60. The coating pump 42 is located on the coating rack 41 and is connected to each nozzle 44. One end of the material extraction pipe 43 extends into the insulating coating 60, and the other end is connected to the coating pump 42.

[0034] It should be noted that the paint pump 42 draws the insulating paint 60 from the paint tank 10 through the extraction pipe 43, and then converts it into atomized particles for high-speed spraying through the nozzle 44. High-pressure spraying overcomes the effects of gravity, penetrating deep into the complex structure of the anchor bolt 70, eliminating blind spots that are difficult to cover with dip coating, ensuring a consistent coating thickness on the surface of the anchor bolt 70, and significantly improving the consistency of insulation performance. The nozzle 44 can be connected to the paint rack 41 via a quick-release interface, allowing for the replacement of nozzles 44 with different flow rates and spray angles according to the specifications of the anchor bolt 70. For example, a fan-shaped nozzle 44 can be used for spraying the shank of the anchor bolt 70, while a conical nozzle 44 can be used for spraying the threaded section of the anchor bolt 70. A float valve can be installed at the end of the extraction pipe 43, which automatically rises and falls with the liquid level in the paint tank 10, ensuring that paint is always drawn from the middle of the liquid surface, preventing bottom sediment particles from clogging the nozzle 44. Both the paint pump 42 and the nozzle 44 are integrated into the paint rack 41, forming an independent closed-loop circulation circuit. By reducing the area of ​​the coating exposed to air, and in conjunction with the sealing structure of the cover plate 21, the emission of volatile substances in the insulating coating 60 can be effectively reduced, thus preventing environmental pollution.

[0035] In one possible implementation, please refer to Figure 3 The bottom wall of the paint rack 41 is provided with a return port 411.

[0036] It should be noted that the return port 411 is located on the bottom wall of the paint rack 41, allowing paint that is not adhering to the anchor bolts 70 to flow back into the paint tank 10, realizing paint recycling, improving paint utilization, and reducing production costs. The return port 411 returns excess paint, promoting paint circulation within the device, preventing sedimentation and stratification caused by prolonged standing, and helping to maintain paint uniformity and stability, ensuring coating quality. The return port 411 prevents paint from flowing and accumulating randomly on the paint rack 41, reducing contamination and simplifying cleaning, thus contributing to a cleaner working environment. The return port 411 also helps maintain stable pressure in the paint pump 42, resulting in more uniform and stable paint spraying at the nozzle 44, thereby improving the coating quality and consistency of the insulating coating on the anchor bolts 70.

[0037] In some embodiments, please refer to Figure 3 A second rotary drive 412 is provided below the coating rack 41. The output end of the second rotary drive 412 is connected to a spiral fan blade 413, which is located inside the insulating coating 60.

[0038] It should be noted that the second rotary drive component 412 can be a motor, which drives the spiral fan blade 413 to rotate within the insulating coating 60. The rotation of the spiral fan blade 413 keeps the insulating coating 60 in a continuous flow state, preventing solid particles in the coating from settling at the bottom of the coating tank 10 due to gravity. This helps maintain the uniformity of the coating, ensuring that the coating composition drawn from the extraction pipe 43 is consistent, and guaranteeing the stable performance of the insulating coating applied to the anchor bolts 70. The rotation of the spiral fan blade 413 can also reduce the viscosity of the coating, giving it better fluidity. When the coating pump 42 draws the coating and sprays it through the nozzle 44, the coating can be sprayed more smoothly, ensuring the normal operation of the nozzle 44 and preventing the nozzle 44 from becoming clogged or spraying unevenly due to excessively high coating viscosity. If the insulating coating 60 is composed of multiple components, the stirring of the spiral fan blade 413 can also ensure that the various components are fully mixed, ensuring that the coating's performance indicators meet the requirements. Due to the improved fluidity of the coating, the power required by the coating pump 42 when drawing the coating is reduced, achieving energy-saving effects.

[0039] For example, please refer to Figure 1 The paint tank 10 is also equipped with a drying component 50, which is located on both sides of the paint inlet 11 and is used to dry the anchor bolts 70 after the paint is applied.

[0040] It should be noted that the drying components 50 are located on both sides of the coating inlet 11. After the cover plate 21 moves the anchor bolts 70 to be coated with insulating coating 60 in the coating tank 10, the cover plate 21 moves the anchor bolts 70 upwards and through the drying components 50. The drying components 50 can quickly dry the coated anchor bolts 70, shortening the production cycle and improving production efficiency. The drying components 50 can dry the anchor bolts 70 in a timely manner, preventing the undried coating from being contaminated by dust, impurities, etc., making the coating surface smoother and more even, improving the appearance quality and performance of the coating. Appropriate drying conditions help the coating cure better, allowing the coating to bond tightly to the surface of the anchor bolts 70, thereby enhancing the adhesion of the coating and improving the protective effect and service life of the coating.

[0041] For example, please refer to Figure 4 and Figure 5 The air drying assembly 50 includes a fan 51 and an air box 52. The fan 51 is mounted on the paint tank 10 and located on one side of the paint inlet 11. The air box 52 is mounted on the paint tank 10 and connected to the fan 51. The air box 52 is provided with evenly distributed air outlets 53.

[0042] It should be noted that the air outlets 53 on the air boxes 52 are evenly distributed, and the air outlets 53 on the two air boxes 52 are spaced apart. Combined with the rotation of the anchor bolts 70, this ensures that the air is evenly distributed on the anchor bolts 70, preventing localized areas from drying too quickly or too slowly. This ensures uniform drying of the coating overall, thereby improving the quality and consistency of the coating. Whether it's the upper, middle, or lower part of the anchor bolts 70, a good drying effect can be achieved within the same timeframe, reducing problems such as coating cracking and peeling caused by uneven drying. The fan 51 provides the airflow, and the air boxes 52 concentrate and guide the airflow, allowing the air energy to effectively act on the surface of the anchor bolts 70, accelerating the evaporation of solvents in the coating, achieving rapid drying, thereby improving production efficiency and shortening the production cycle.

[0043] In one possible implementation, please refer to Figure 1 Multiple sliding rods 23 are provided above the cover plate 21, and each sliding rod 23 is slidably connected to the lifting frame 20.

[0044] It should be noted that the slide bar 23 provides precise guidance for the up-and-down sliding of the cover plate 21, ensuring that the cover plate 21 can move smoothly along a fixed path during the lifting and lowering process, avoiding shaking, tilting, or jamming, effectively preventing paint evaporation, and providing a stable working environment for the coating operation. The slide bar 23 makes the lifting and lowering movement of the cover plate 21 smoother and more precise, allowing the cover plate 21 to smoothly reach the predetermined position. The slide bar 23 helps to achieve smooth opening and closing of the cover plate 21 during the coating operation, improving the operational stability of the entire coating device.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
