Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance equipment, in particular to a device for spraying corrosion-resistant material on a curbstone. Background Art

[0002] Curbstones are boundary stones used at the edge of the road. They are the boundaries that distinguish the carriageway, sidewalk, green space, isolation belt and other parts of the road. They play a role in ensuring the safety of pedestrians and vehicles and keeping the edge of the road neat.

[0003] During use, curbstones will be subject to natural chemical corrosion, such as acid rain produced by the discharge of N2, CO2, and H2O in nature, which will cause corrosion of the curbstone. On the other hand, curbstones will also be subject to man-made chemical corrosion, mainly referring to waste gas discharged from industry, such as nitrogen oxides, hydrocarbons, sulfur oxides, carbon oxides and acidic particles, which will cause corrosion to the stone and affect its lifespan. Salt-containing snow-melting agents in winter and acidic or alkaline waste residues and waste liquids discharged from industry will also corrode curbstones and cause surface damage and reduced strength.

[0004] At present, the repair of curbstones is mostly done manually, using manual application of paint for repair, but this method has the problems of cumbersome operation, long operation time, inability to control the amount of paint, uneven application, etc.; at the same time, existing curbstone repairs are mostly applied with paint that has good compatibility with the curbstone, but the paint generally has poor waterproof properties, and water can still penetrate into the curbstone, resulting in poor waterproof and anti-corrosion effects.

The base coating spray assembly 2 and the rotating brush assembly 4 are placed along the width direction of the base plate 1. The discharge end of the base coating spray assembly 2 is arranged directly above the rotating brush assembly 4. Since the base coating is relatively viscous, the base coating is sprayed from the discharge end of the base coating spray assembly 2 and falls on the rotating brush assembly 4 below. A first rotating brush 42 is provided on the rotating brush assembly 4. The first rotating brush 42 rotates axially below the discharge end of the base coating spray assembly 2. After the base coating falls on the first rotating brush 42 of the rotating brush assembly 4, the first rotating brush 42 rotates to apply the coating to the curb so that the coating is evenly applied.

[0031] like Figure 2 As shown, the primer spraying assembly 2 includes a primer storage tank 21 and a primer output pipe 22. The bottom of the primer storage tank 21 is fixed above the bottom plate 1. The primer storage tank 21 is provided with a primer inlet 21a and a primer outlet 21b. The primer inlet 21a and the primer outlet 21b are connected to the inside of the primer storage tank 21. The primer inlet 21a is provided at the top of the primer storage tank 21, and the primer outlet 21b is provided at the side end of the primer storage tank 21.

The projection of the fixed groove 51 in the horizontal direction is C-shaped. The length direction of the fixed groove 51 is the vertical direction, and the bottom of the fixed groove 51 is fixed above the bottom plate. The rotating shaft 52 is arranged on the inner side of the fixed groove 51 close to one end of the bottom plate 1. The first connecting rod 41a passes through the rotating shaft below and rotates axially relative to the rotating shaft 52. When the curb needs to be painted, the rotating brush assembly 4 is rotated to make the upper part of the first connecting rod 41a detach from the fixed groove 51. At this time, the first connecting rod 41a is parallel to the upper surface of the bottom plate 1, and the second connecting rod 41b is vertically downward. The width of the inner side of the fixed groove 51 is greater than the width of the first connecting rod 41a, so that the first connecting rod 41a enters the fixed groove 51 after axial rotation.

[0039] An electric control box 7 is also provided on the base plate 1, and the output ends of the electric control box 7 are respectively connected to the base coating spraying assembly 2 and the surface coating spraying assembly 3. The electric control box 7 can control the flow rate of the discharge port of the base coating and the surface coating to ensure that the thickness of the coating meets the anti-corrosion requirements, improve the coverage of the base coating and the surface coating, and adjust the spraying interval between the base coating spraying assembly 2 and the surface coating spraying assembly 3, so as to carry out spraying operations under construction conditions of different temperature and humidity and different weather conditions.

[0040] When in use, the equipment is moved to the position where work is required via the universal wheel 6, the base coat paint is sprayed onto the rotating brush assembly 4 via the base coat paint spraying assembly 2, the rotating brush assembly 4 rotates to coat the curbstone so that the base coat paint is evenly coated, and then the equipment is moved, the discharge end of the surface coat paint spraying assembly 2 is aimed at the curbstone, and the surface coat paint spraying assembly 3 sprays the surface coat paint onto the curbstone to complete the repair of the curbstone.

[0041] like Fig. 9 As shown, when the device is not in use, the bottom layer paint output pipe 22 and the surface layer paint output pipe 32 can be removed, and the first connecting rod 41a can be axially rotated into the fixing groove 51 and locked and fixed by the locking assembly 53, which can effectively reduce the space on the side of the device and facilitate storage.
