[0003] After searching, the Chinese utility model patent with publication number CN216446436U is named as a paint spraying device with drying function. The device can adjust the spraying position by adding universal wheels and screw slides, which greatly realizes the automation of the entire device and reduces the manual workload. By adding a drying fan, the paint surface that has just been sprayed can be dried to prevent the wet paint surface from being contaminated by dust in the air, which would deteriorate the visual effect.

[0004] However, it was found during use that when anti-corrosion treatment is carried out on bridges, anti-corrosion paint is usually applied to the outer wall of the bridge. In particular, when spraying the bottom surface of an elevated bridge, workers need to use a lift to spray, and after spraying, it is usually dried by natural air drying. However, this method will cause the paint to take too long to dry, and the anti-corrosion paint is easy to sag, which can easily cause uneven paint thickness, thereby affecting the anti-corrosion effect and durability of the bridge, and even affecting the quality of the bridge.

[0033] A hinge seat 8 is fixedly connected to the bottom surface of the drying box 7, and the rear wall of the upper end of the support rod 4 is rotatably connected to the second cylinder 13 through a mounting seat.

The movable frame 9 is rotatably connected to a plurality of rollers 901 in a uniformly arranged structure; the rollers 901 are adapted to contact with the protrusions at the bottom of the bridge, thereby reducing the influence of the protrusions on the movable frame 9. When the protrusions contact with the rollers 901, the springs 702 are compressed, and the movable frame 9 slides downward along the annular groove 701 to protect the movable frame 9.

[0035] The electric heating tube 10 is in a circuitous shape, and both ends of the electric heating tube 10 are connected to electrode ends 1001. The electrode ends 1001 penetrate the inner wall of the drying box 7 and extend to the outside. The electric heating tube 10 is located at the upper end of the drying box 7. The electric heating tube 10 is heated by the electrode end 1001, and the sprayed paint is heated by the electric heating tube 10. At the same time, the electric heating tube 10 heats the hot air flowing inside the drying box 7 again, thereby increasing the air temperature.

[0036] The hot air drying component 11 includes a blower 1101, the air outlet end of the blower 1101 is connected to an air inlet pipe 1102, the middle part of the air inlet pipe 1102 is connected to an air heater 1103, the blower 1101 and the air heater 1103 are both installed on the bottom surface of the drying box 7 through a mounting seat, the air inlet pipe 1102 penetrates the outer wall of the drying box 7 and extends to the inside, the air inlet pipe 1102 located inside the drying box 7 is connected to a delivery pipe 1104, the top surface of the delivery pipe 1104 is in a uniformly arranged structure and is connected to a plurality of distribution blocks 1105, both ends of the bottom surface of the distribution block 1105 are fixedly connected to the bottom surface of the drying box 7; the external air is sucked and delivered to the inside of the air inlet pipe 1102 by the blower 1101, heated by the air heater 1103 and then delivered to the inside of the delivery pipe 1104, and continuously delivered from the distribution block 1105 into the inside of the drying box 7, and the flowing hot air is blown to the outer wall of the anti-corrosion paint on the bottom surface of the bridge for drying.

[0037] Working principle: first, the electric drive wheel 2 drives the utility model to move to a suitable use position, and then the piston rods of the two first cylinders 5 move upward at the same time, so that the piston rods of the first cylinder 5 drive the push block 6 to move synchronously, so that the support rod 4 slides upward along the sleeve 3, and after the support rod 4 pushes the drying box 7 to move to the bottom surface of the bridge, the piston rod of the second cylinder 13 pushes the hinge seat 8 to drive the drying box 7 to rotate to a suitable drying use angle, and the support rod 4 pushes the sliding movable frame 9 on the drying box 7 to move synchronously, so that the outer wall of the roller 901 on the movable frame 9 and the gap of the bottom surface of the bridge are matched, and the anti-corrosion paint on the bottom of the bridge is dried by the hot air drying component 11 and the electric heating tube 10, which improves the drying efficiency of the anti-corrosion paint of the bridge, reduces the occurrence of sagging of the anti-corrosion paint, makes the sprayed anti-corrosion paint more uniform, and improves the drying effect of the anti-corrosion paint;

[0038] The roller 901 is adapted to contact with the protrusion at the bottom of the bridge, thereby reducing the influence of the protrusion on the movable frame 9. When the protrusion contacts the roller 901, the spring 702 is compressed, and the movable frame 9 slides downward along the annular groove 701, thereby protecting the movable frame 9 and reducing the occurrence of collision damage between the movable frame 9 and the protrusion of the bridge.

[0039] During drying, external air is sucked in and transported to the inside of the air inlet pipe 1102 by the blower 1101, heated by the air heater 1103, and then transported to the inside of the delivery pipe 1104, and continuously transported from the distribution block 1105 into the drying box 7.

At the same time, the electric heating tube 10 heats the hot air flowing in the drying box 7 again, thereby increasing the air temperature, improving the drying efficiency of the anti-corrosion paint, making the sprayed anti-corrosion paint more uniform, reducing the occurrence of sagging, improving the coating protection effect of the anti-corrosion paint, and improving the anti-corrosion effect and durability of the bridge.

[0040] Embodiment 2

[0041] like Figure 1 , Figure 3 and Figure 5 As shown, on the basis of Example 1, the pressure relief assembly 12 includes a pressure relief block 1201, and the outer wall of the movable frame 9 is evenly arranged and has multiple pressure relief holes 1202, the pressure relief block 1201 is located inside the pressure relief hole 1202, and the lower end of the pressure relief block 1201 is rotatably connected to the movable frame 9, and the inner wall of the pressure relief block 1201 is symmetrically structured and fixedly connected with two tension springs 1203, the upper end of the tension spring 1203 is fixedly connected with a fixed block 1204, and the outer end of the fixed block 1204 is fixedly connected to the inner wall of the movable frame 9; the excessive pressure pushes the pressure relief block 1201 inside the pressure relief hole 1202 to rotate along the movable frame 9, and at this time the tension spring 1203 is stretched, and the pressure relief hole 1202 is opened to discharge the hot air with excessive pressure to the outside, thereby reducing the occurrence of damage to the drying box 7 due to excessive pressure.

[0042] During use, since the blower 1101 continuously delivers hot air to the drying box 7, the hot air pressure inside the drying box 7 cannot be discharged from the gap between the roller 901 and the bottom surface of the bridge in time, which may easily cause the hot air pressure inside the drying box 7 to be too high. At this time, the excessive pressure pushes the pressure relief block 1201 inside the pressure relief hole 1202 to rotate along the movable frame 9. At this time, the tension spring 1203 is stretched, and the pressure relief hole 1202 is opened to discharge the hot air with excessive pressure to the outside. When the internal pressure of the drying box 7 is reduced, the restoring force of the tension spring 1203 drives the pressure relief block 1201 to seal the pressure relief hole 1202, which facilitates the continuous use of the drying box 7, reduces the occurrence of damage to the drying box 7 due to excessive pressure, and facilitates the continuous drying use of the drying box 7.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
