Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, and in particular to a spray painting equipment for construction engineering. Background Technology

[0002] In building construction, the round pipes used in water supply, fire protection, and drainage systems are mostly made of metals such as carbon steel and cast iron. In underground, outdoor, and humid environments, they are prone to electrochemical corrosion due to contact with moisture, salt, and pollutants. This leads to thinning of the pipe walls, decreased strength, and even perforation and rupture, causing safety hazards and increasing maintenance costs. Pipe painting, on the other hand, forms a protective film that isolates air and moisture, thereby slowing down or preventing metal oxidation and corrosion, and extending the service life of the pipes.

[0003] Currently, many construction sites still commonly use manual roller painting or handheld spray guns. For longer cylindrical pipes, when painting them flat or at an angle, workers must first paint the top half of the curved surface before flipping the pipe to paint the other half. This process is tedious and time-consuming, and because manual operation makes it difficult to ensure consistent pressure and speed, it easily leads to uneven paint application. Furthermore, during the pipe flipping process, the painted paint tends to scatter and accumulate, wasting paint and causing oil droplets to form on the surface, affecting aesthetics and protective effectiveness. If the pipe is tilted for painting, the oil droplet phenomenon is even more severe, with paint continuously accumulating and sliding down to the lower side, polluting the surrounding environment and damaging the integrity of the paint surface. Therefore, we propose a painting device for construction projects to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a painting device for construction engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A painting device for construction engineering includes two T-shaped guide rails, two baffles fixedly connected between the two T-shaped guide rails, and two guide rods fixedly connected between the two baffles. A hydraulic cylinder is fixedly connected to the outer wall of one of the baffles. A first placement plate and a second placement plate are sleeved on the outer walls of the two guide rods. The outer wall of the output end of the hydraulic cylinder is fixedly connected to the outer wall of the first placement plate. The second placement plate is fixedly connected to the outer wall of the other baffle. Two U-shaped plates are fixedly connected to the top of each of the first and second placement plates. Two through holes are opened on the outer walls of the four U-shaped plates. The same T-shaped roller is rotatably connected to the inner wall of each of the two through holes. A servo motor is fixedly connected to the outer wall of one of the U-shaped plates. The outer wall of the output shaft of the servo motor is fixedly connected to the outer wall of one of the T-shaped rollers. Vertical sleeves are fixedly connected to the outer walls of the two U-shaped plates. Vertical rods are threadedly connected to the inner walls of the two vertical sleeves. A painting assembly is provided on the top of the T-shaped guide rails.

[0007] Preferably, the painting assembly includes a paint spray box, the top of which is fixedly connected to four pulleys, which are slidably connected in pairs to two T-shaped guide rails. A frame is fixedly connected inside the paint spray box, and a paint gun is fixedly connected to the outer wall of the frame. The painting assembly is used to paint the round tube.

[0008] Preferably, bearings are fixedly fitted at both ends of the T-shaped roller, and the outer ring of the bearing is fixedly connected to the inner wall of the through hole, so that the T-shaped roller can rotate by means of bearings.

[0009] Preferably, the outer wall of the paint spray box has two inlet / outlet slots, which have a certain height and width, and are fully accommodating the passage of the two vertical rods and the first placement plate.

[0010] Preferably, a linear motor is fixedly connected to the outer wall of one of the T-shaped guide rails, and the moving end of the linear motor is fixedly connected to the outer wall of the paint spray box.

[0011] Preferably, one end of the paint gun is fixedly connected to a corrugated telescopic tube, and one end of the corrugated telescopic tube penetrates the outer wall of the paint box and is fixedly connected to a diaphragm pump. By setting the corrugated telescopic tube, the paint can be delivered to the paint gun when the paint box is moved.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution uses a hydraulic cylinder to move the first placement plate along the guide rod, which can flexibly adapt to round tubes of different lengths and solves the problem of inconvenience in manually handling round tubes of different specifications.

[0014] Four height-adjustable vertical bars can effectively limit the side movement, preventing the round tube from slipping off the T-roller during rotation and ensuring operational safety;

[0015] A servo motor drives a T-shaped roller to rotate the round tube stably, and a linear motor drives the paint spray box to slide along the guide rail. This eliminates the need for manual flipping and hand operation, greatly reducing labor costs and labor intensity, while also avoiding the problems of uneven force and speed in manual operation.

[0016] The coordinated operation of the rotating round tube and the moving paint spray box enables uniform spraying of the outer wall of the round tube, effectively preventing paint from scattering, agglomerating, or clumping, thus improving the quality of the paint spraying and the utilization rate of the paint.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-3 As shown, a painting device for construction engineering is disclosed, including two T-shaped guide rails 1, two baffles 2 fixedly connected between the two T-shaped guide rails 1, and two guide rods 3 fixedly connected between the two baffles 2. The two baffles 2 serve two purposes: firstly, they limit the boundary and prevent the first placement plate 5 from sliding beyond the stroke range along the guide rods 3 under the drive of the hydraulic cylinder 4, thus avoiding structural collision damage; secondly, they serve as a fixed carrier for the guide rods 3, thereby enhancing the installation stability of the guide rods 3.

[0024] One of the baffles 2 has a hydraulic cylinder 4 fixedly connected to its outer wall, and the outer walls of the two guide rods 3 are fitted with a first placement plate 5 and a second placement plate 6. The second placement plate 6 cooperates with the movable first placement plate 5 to jointly bear the weight of the round tube.

[0025] The outer wall of the output end of the hydraulic cylinder 4 is fixedly connected to the outer wall of the first placement plate 5, and the second placement plate 6 is fixedly connected to the outer wall of another baffle 2. The top of the first placement plate 5 and the second placement plate 6 are both fixedly connected to two U-shaped plates 7, and the outer wall of the U-shaped plates 7 is chamfered.

[0026] Each of the four U-shaped plates 7 has two through holes on its outer wall. The inner wall of each through hole is rotatably connected to the same T-shaped roller 8. Bearings are fixedly fitted at both ends of the T-shaped roller 8. The outer ring of the bearing is fixedly connected to the inner wall of the through hole. A servo motor 9 is fixedly connected to the outer wall of one of the U-shaped plates 7. The servo motor 9 is supported by an existing bracket welded on the U-shaped plate 7. The outer wall of the output shaft of the servo motor 9 is fixedly connected to the outer wall of one of the T-shaped rollers 8.

[0027] The outer walls of the four U-shaped plates 7 are all fixedly connected with vertical sleeves 10, and the inner walls of the four vertical sleeves 10 are all threaded with vertical rods 11. The height can be adjusted through the vertical sleeves 10. The adjusted vertical rods 11 can effectively limit the movement from both sides of the round tube, further preventing the round tube from slipping out of the T-shaped roller 8 due to accidental shaking during rotation or painting, thus improving the safety and stability of the operation process.

[0028] The top of the T-shaped guide rail 1 is equipped with a spray painting assembly, which includes a spray paint box 12. The outer wall of the spray paint box 12 has two inlet and outlet slots. The top of the spray paint box 12 is fixedly connected with four pulleys. The four pulleys are slidably connected to two T-shaped guide rails 1 in pairs. The "T"-shaped cross-section design of the two T-shaped guide rails 1 can cooperate with the pulleys at the bottom of the spray paint box 12, which not only provides a stable track for the sliding of the spray paint box 12, but also limits the lateral displacement of the pulleys, ensuring that the spray paint box 12 moves smoothly along the preset path.

[0029] A linear motor 13 is fixedly connected to the outer wall of one of the T-shaped guide rails 1. The moving end of the linear motor 13 is fixedly connected to the outer wall of the paint spray box 12. A frame 14 is fixedly connected inside the paint spray box 12. A paint spray gun 15 (WA-101) is fixedly connected to the outer wall of the frame 14. The nozzle of the paint spray gun 15 (WA-101) faces downward. The paint spray gun 15 (WA-101) can spray the paint delivered by the diaphragm pump evenly on the outer wall of the round tube in an atomized state.

[0030] One end of the paint spray gun 15 is fixedly connected to a corrugated telescopic tube, and one end of the corrugated telescopic tube penetrates the outer wall of the paint spray box 12 and is fixedly connected to a diaphragm pump.

[0031] Working principle: During use, based on the length of the round tube, the first placement plate 5 is moved along the two guide rods 3 by the operation of the hydraulic cylinder 4, adjusting the distance between it and the second placement plate 6. The four vertical sleeves 10 rotate the four vertical rods 11, adjusting the height of the four vertical rods 11, which serve as lateral limiters to prevent the round tube from slipping out of the T-shaped rollers 8. Heavier round tubes can be hoisted using existing hoisting equipment. The two ends of the round tube are located at the top of the left and right T-shaped rollers 8 respectively. As the servo motor 9 operates, it drives the connected T-shaped rollers 8 to rotate, cooperating with the adjacent T-shaped rollers 8 to drive one end of the round tube to rotate. The other end of the round tube rotates through the other two T-shaped rollers 8. The linear motor 13 operates, driving the paint spray box 12 to slide along the top of the two T-shaped guide rails 1. One end of the round tube enters the paint spray box 12 from the inlet / outlet slot. The diaphragm pump operates to pump external paint (in buckets) into the paint spray gun 15, which then sprays it downwards onto the outer wall of the round tube. With the rotation of the round tube, it can be sprayed evenly.

[0032] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the hydraulic cylinder 4, servo motor 9, linear motor 13, paint spray gun 15, and diaphragm pump to facilitate overall control of the operation.

[0033] All standard parts used in this utility model can be purchased from the market. Irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. Furthermore, the structure and principle of the components known to those skilled in the art can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0034] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
