Description

Technical Field

[0001] This utility model belongs to the field of steel pipe coating technology, specifically relating to a coating mechanism for building steel structures. Background Technology

[0002] Steel structures, as a major form of modern architecture, offer advantages such as light weight, high strength, good seismic performance, short construction period, high degree of industrialization, and large space utilization at room temperature, making them widely used by investors and saving them money. However, steel structures also have a significant drawback: poor fire resistance. Although steel is a non-combustible material, it is a good conductor of heat and easily conducts heat. When the temperature exceeds 300 degrees Celsius, the yield point and ultimate strength of steel decrease significantly, and at 600 degrees Celsius, the strength is almost zero. In a fire, an unprotected steel structure can reach a temperature of over 540 degrees Celsius within just 15 minutes, causing the components to twist and deform, leading to the collapse and destruction of the building. The deformed steel structure is also irreparable. Therefore, fire protection measures must be taken for steel structures, such as applying fire-retardant coatings or flame retardants.

[0003] Current methods typically involve using spraying equipment to coat steel structures. During the spraying process, any paint that does not adhere to the steel structure surface will disperse into the surrounding air, resulting in not only a waste of paint but also air pollution, which is very environmentally unfriendly. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed painting mechanism for building steel structures in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A painting mechanism for building steel structures includes a paint collection box with an open top. Support plates are fixedly connected to both ends of the paint collection box. Clamping structures are installed on both support plates. A reciprocating screw is rotatably connected between the two support plates above the clamping structures. A servo motor for driving the reciprocating screw is installed on the outer side of one of the support plates. The end of the reciprocating screw away from the servo motor is connected to the clamping structure via a linkage device. A guide rod is fixedly installed between the top ends of the two support plates. A slide is screwed onto the reciprocating screw. The top of the slide is fitted onto the guide rod and slidably connected to it. A paint nozzle is fixedly connected to the lower surface of the slide. A peristaltic pump is installed on one side of the outer wall of the paint collection box. The output end of the peristaltic pump is connected to the paint nozzle via a delivery pipe. Air nozzles are fixedly connected to the slides on both sides of the paint nozzle. Two suction pumps with suction ends extending into the paint collection box are installed on the outer wall of the paint collection box. The exhaust ends of the suction pumps are connected to the air nozzles via suction pipes.

[0007] As a further optimization of this utility model, inclined plates are fixedly connected to the inner walls of the front and rear sides of the top of the paint collection box. The adjacent sides of the two inclined plates are inclined downwards, and the upper surface of the inclined plates is coated with an anti-sticking coating.

[0008] As a further optimization of this utility model, the clamping structure includes a rotating tube rotatably connected to the support plate. Each of the two adjacent ends of the rotating tubes is slidably connected with a prismatic slide rod whose size is adapted to the inner cavity of the rotating tube. One end of the prismatic slide rod located inside the rotating tube is fixed to the inner wall of the rotating tube by a spring, and the other end of the prismatic slide rod located outside the rotating tube is fixedly connected to a clamping plate.

[0009] As a further optimization of this utility model, the side of the clamping plate away from the prismatic slide bar is integrally formed with a limiting post with a cylindrical structure, the diameter of which is equal to the inner diameter of the steel pipe to be painted.

[0010] As a further optimization of this utility model, the linkage device includes a driven gear fixedly sleeved on one of the rotating tubes, and a driving gear fixedly sleeved on the end of the reciprocating screw away from the servo motor, wherein the driving gear and the driven gear mesh with each other.

[0011] As a further optimization of this utility model, both the material conveying pipe and the air extraction pipe are corrugated pipes with extendable length, and a heater for heating air is installed at the connection between the air extraction pipe and the air extraction pump.

[0012] The beneficial effects of this utility model are as follows: During the coating process on the steel pipe, the user can start the air pump, which can extract the air from the coating collection box. After being heated by the heater, the air is transported to the nozzle through the air extraction pipe. The hot air is sprayed out through the nozzle to dry the coating on the steel pipe. At the same time, the negative pressure generated by the reduced air density in the coating collection box can draw in the excess coating during the coating process and collect it, thereby reducing coating waste and avoiding coating pollution of the air.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, a painting mechanism for building steel structures includes a paint collection box 1 with an open top. Inclined plates 2 are fixedly connected to the inner walls of the front and rear sides of the top of the paint collection box 1. The adjacent sides of the two inclined plates 2 are inclined downward. The upper surface of the inclined plates 2 is coated with an anti-stick coating. The paint collection box 1 is set up to collect excess paint during spraying. The inclined plates 2 are set up and coated with an anti-stick coating so that the paint can slide down the inclined plates 2 into the paint collection box 1 after falling on the inclined plates 2 for collection.

[0021] Both ends of the paint collection box 1 are fixedly connected to support plates 3. Each support plate 3 is equipped with a clamping structure, which includes a rotating tube 4 rotatably connected to the support plate 3. Each of the two adjacent ends of the rotating tube 4 is slidably connected to a prismatic slide rod 5 whose size is adapted to the inner cavity of the rotating tube 4. One end of the prismatic slide rod 5 located inside the rotating tube 4 is fixed to the inner wall of the rotating tube 4 by a spring 6. The other end of the prismatic slide rod 5 located outside the rotating tube 4 is fixedly connected to a clamping plate 7. When it is necessary to paint the steel pipe, the prismatic slide rod 5 can be pushed into the rotating tube 4 to compress the spring 6 installed in the rotating tube 4, adjust the distance between the two clamping plates 7, and then place the steel pipe between the two clamping plates 7. After releasing the prismatic slide rod 5, the spring 6 pushes the two clamping plates 7 to move towards each other under its own elastic force, thereby clamping the steel pipe between the two clamping plates 7 above the paint collection box 1.

[0022] The clamping plate 7 has an integrally formed cylindrical limiting post on the side away from the prismatic slide bar 5. The diameter of the limiting post is equal to the inner diameter of the steel pipe to be coated. When the clamping plate 7 clamps the steel pipe, the limiting post can be inserted into the end of the steel pipe to avoid the steel pipe slipping out between the two clamping plates 7 during the coating process.

[0023] A reciprocating screw 8 is rotatably connected between two support plates 3 above the clamping structure. A servo motor 9 for driving the reciprocating screw 8 to rotate is installed on the outside of one of the support plates 3. The end of the reciprocating screw 8 away from the servo motor 9 is connected to the clamping structure through a linkage device. The linkage device includes a driven gear 11 fixedly sleeved on one of the rotating tubes 4, and a driving gear 10 fixedly sleeved on the end of the reciprocating screw 8 away from the servo motor 9. The driving gear 10 and the driven gear 11 mesh with each other. When the servo motor 9 is started to drive the reciprocating screw 8 to rotate, the driving gear 10 installed at the end of the reciprocating screw 8 can drive the driven gear 11 fixedly connected to the rotating tube 4 to rotate synchronously, thereby driving the steel pipe clamped on the clamping structure to rotate, which facilitates the coating work on the periphery of the steel pipe.

[0024] A guide rod 12 is fixedly installed between the top ends of the two support plates 3. A slide block 13 is screwed onto the reciprocating screw 8. The top of the slide block 13 is sleeved on the guide rod 12 and slidably connected to the guide rod 12. Since the slide block 13 is screwed onto the reciprocating screw 8 and guided by the guide rod 12, when the reciprocating screw 8 rotates under the drive of the servo motor 9, the slide block 13 can reciprocate along the length direction of the reciprocating screw 8.

[0025] A paint nozzle 14 is fixedly connected to the lower surface of the slide 13. A peristaltic pump 16 is installed on one side of the outer wall of the paint collection box 1. The output end of the peristaltic pump 16 is connected to the paint nozzle 14 through a conveying pipe 15. The input end of the peristaltic pump 16 is connected to an external paint tank. When the slide 13 drives the paint nozzle 14 to move along the length of the reciprocating screw 8, the peristaltic pump 16 is activated to transport the paint along the conveying pipe 15 to the paint nozzle 14, and then sprays it onto the rotating steel pipe below through the paint nozzle 14 to achieve the coating work on the steel pipe.

[0026] Air nozzles 17 are fixedly connected to the slides 13 on both sides of the paint nozzle 14. Two air pumps 19 with suction ends extending into the paint collection box 1 are installed on the outer wall of the paint collection box 1. The exhaust end of the air pump 19 is connected to the air nozzle 17 through an air suction pipe 18. During the spraying of the steel pipe, the air pump 19 can be started at the same time. The air pump 19 can suck the air in the paint collection box 1 to form a negative pressure in the paint collection box 1. The negative pressure is used to suck the excess paint in the air into the paint collection box 1, so as to avoid the paint being directly dispersed in the air, which not only wastes paint but also pollutes the ambient air.

[0027] Both the conveying pipe 15 and the suction pipe 18 are corrugated pipes with extendable lengths, so that when the slide 13 moves along the length of the reciprocating screw 8, both the conveying pipe 15 and the suction pipe 18 can adapt by changing their own lengths, thus minimizing the risk of the conveying pipe 15 and the suction pipe 18 being pulled and broken. A heater 20 for heating air is installed at the connection between the suction pipe 18 and the suction pump 19. When in use, the user can turn on the heater 20 to heat the air passing through the suction pipe 18. When the heated air is sprayed out by the nozzle 17 onto the steel pipe, it can quickly dry the paint sprayed on the steel pipe, thereby improving the coating efficiency of the steel structure.

[0028] It should be noted that, in use, this coating mechanism for building steel structures involves clamping and fixing the steel pipe to be coated between two clamping plates 7. Then, the servo motor 9 is started to drive the reciprocating screw 8 to rotate, which, in conjunction with the guide rod 12, drives the slide 13, which is threadedly connected to the reciprocating screw 8, to move. Simultaneously, the driving gear 10 and the driven gear 11 drive the steel pipe clamped between the two clamping plates 7 to rotate. During the movement of the slide 13, the paint nozzle 14 moves along the steel pipe. At this time, the peristaltic pump 16 is turned on, and the paint is transported along the conveying pipe 15 to the coating nozzle. The paint is evenly sprayed onto the outside of the rotating steel pipe through the paint nozzle 14. During the spraying process, the user can start the air pump 19, which can extract the air from the paint collection box 1. After being heated by the heater 20, the air is transported to the air nozzle 17 through the air extraction pipe 18. The hot air is sprayed out through the air nozzle 17 to dry the paint. At the same time, the negative pressure generated in the paint collection box 1 can suck the excess paint in the paint collection box 1 during the spraying process and collect it, so as to reduce paint waste and avoid paint pollution of the air.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
