Description

[0001] The present application relates to the technical field of spraying equipment, and in particular to a method and a device for spraying a concrete anti-freeze coating. Background Art

[0002] When spraying anti-salt frost coating on crash barriers, pneumatic spraying equipment is generally used. Existing pneumatic spraying equipment has the following technical drawbacks: first, the atomized coating pollutes the environment; second, the coating thickness is uneven.

[0003] Regarding the first technical defect, the pneumatic spraying equipment absorbs the paint through pressure, atomizes the paint, and sprays it along the crash barrier. The atomized paint will diffuse in the air and cause air pollution.

[0004] As for the second technical defect, since the wall of the crash barrier is perpendicular to the road surface, when spraying the polyurethane paint, the paint will flow downward along the wall, causing the thickness of the upper coating to fail to meet the waterproof standard.

[0005] In response to the above two technical deficiencies, the present application provides a method and a device for spraying a concrete anti-freeze coating. Summary of the Invention

[0023] Example 1 When spraying anti-salt frost coating on crash barriers, spray guns are generally used. The existing spray gun equipment for crash barrier spraying has the following technical defects: First, the atomized paint pollutes the environment; second, the thickness of the coating is uneven.

[0024] Regarding the first technical defect, the spray gun absorbs the paint through pressure, atomizes the paint, and sprays it along the crash barrier. The atomized paint will diffuse in the air and cause air pollution.

[0025] As for the second technical defect, since the wall of the crash barrier is perpendicular to the road surface, when spraying the polyurethane paint, the paint will flow downward along the wall, causing the thickness of the upper coating to fail to meet the waterproof standard.

[0026] In view of the above two technical defects, the embodiment of the present application provides a concrete anti-freeze coating spraying device, such as Figure 1 As shown, it includes a coating mechanism 100 and a spraying mechanism 200.

[0027] Specifically, the coating mechanism 100 is provided with a coating roller 120 and a roller mounting plate 110 .

[0028] The roller mounting plate 110 is provided with N bent plate surfaces along the length direction, and movable joints 116 are provided between adjacent bent plate surfaces, where N is an integer greater than or equal to 2.

[0029] like Figure 1 As shown, the roller mounting plate 110 is provided with three bent plate surfaces, the first bent plate surface 111, the second bent plate surface 112 and the third bent plate surface 113 are spliced ​​in sequence along the length direction of the roller mounting plate 110, and adjacent bent plate surfaces are movably connected through movable joints 116, so that adjacent bent plate surfaces can rotate around the movable joints 116.

[0030] Furthermore, on the top surface of the roller mounting plate 110 , a bending driver 114 is provided between adjacent bending plate surfaces, and the bending driver 114 is used to adjust the angle between the adjacent bending plate surfaces.

[0031] In the embodiments of this application, Figure 1 As shown, the bending driver 114 is provided with a fixed end and a telescopic end, wherein the fixed end and the telescopic end are respectively movably connected to the top surface of the adjacent bending plate surface. The telescopic end is used to extend and retract along the length direction of the roller mounting plate 110.

[0032] When the telescopic end of the bending driver 114 is extended, the angle between the two adjacent bending plate surfaces increases. When the telescopic end of the bending driver 114 is retracted, the angle between the two adjacent bending plate surfaces decreases.

[0033] The roller mounting plate 110 shown in the embodiment of the present application is provided with three bending plate surfaces. The shape of the roller mounting plate 110 is changed by controlling the bending driver 114 to adapt to the wall shape of the anti-collision wall, such as Figure 2 shown.

[0034] The coating mechanism 100 of the embodiment of the present application operates by absorbing polyurethane coating through the coating roller 120 .

[0035] like Figure 1 As shown, the paint roller 120 is mounted on the bottom surface of the roller mounting plate 110. Specifically, two roller mounting seats 115 are provided at both ends of the bottom surface of the roller mounting plate 110 along the length direction. The roller mounting seats 115 are provided with roller head mounting holes, and the paint roller 120 is mounted in the roller head mounting holes on the bottom surface of the roller mounting plate 110.

[0039] Furthermore, the roller mounting plate 110 is provided with a paint receiving groove along its length, and a paint flow hole is provided at the bottom of the paint receiving groove. The paint flow hole penetrates the roller mounting plate 110 along the normal direction of the plate surface of the roller mounting plate 110.

The paint nozzles face the paint flow hole, where M is an integer greater than or equal to 1.

[0040] Furthermore, the spraying mechanism is used to extract paint into the paint spraying pipe; the spraying mechanism is connected to the anti-salt and anti-freeze paint barrel and the paint spraying pipe through a pipeline.

[0041] like Figure 3 As shown, the concrete anti-salt-freeze coating spraying device further includes a device mounting bracket 200; the device mounting bracket 200 is used to fix the concrete anti-salt-freeze coating spraying device on the traveling vehicle.

[0042] One end of the device mounting bracket 200 is fixed on the traveling vehicle, and the other end is used to mount the concrete anti-salt and anti-freeze coating spraying device.
