Description

Road surface coating film application device {apparatus for forming coating film on road}

The present invention relates to a road surface coating film application apparatus, and more particularly, to a road surface coating film application apparatus capable of forming a coating film by spraying a coating film composition to be applied on a road surface through a nozzle body.

In general, road pavement is a road surface structure that is treated to protect and strengthen the road surface and increase flatness to facilitate the passage of people and vehicles.

Road pavement is broadly classified into asphalt (bituminous) pavement, concrete pavement, and block pavement according to the material of the surface layer. Asphalt pavement is composed of aggregates such as asphalt or crushed stone condensed by tar in the surface layer, and is also called asphalt pavement and tar pavement, and currently occupies most of roads in countries around the world. Concrete-based pavement is a concrete pavement in which concrete is placed on the surface. In addition to concrete and ordinary concrete pavement with wire mesh inserted into concrete, there are reinforced concrete pavement prestressed concrete pavement, etc., and block pavement is stone, brick, cement, wood, asphalt. It is made by laying various blocks such as etc. on the surface layer, and it is currently not used much on roadways, but is used for sidewalks and photons.

In such a road, various road paving materials and paving methods that are environmentally friendly and that can give a sense of stability to pedestrians have been proposed and applied.

On the other hand, in order to prevent the car from sliding off the road surface, multiple anti-skid parts are installed at intervals on the downhill lane or curve of the road to increase the friction coefficient between the tire and the road surface, so that the driver passing the anti-slip installation area can reduce the driving speed. It is designed to prevent traffic accidents in advance by not only inducing, but also providing irregularities so that the vehicle does not slip or lose balance due to speed.

A method of installing such an anti-slip part uses steel-making slag or ceramic aggregate as an anti-skid aggregate, and directly constructs it on a road surface using a fluorine-epoxy modified resin or, in some cases, an epoxy adhesive.

That is, an adhesive was applied to the road surface, aggregate was sprinkled thereon, and then an anti-skid layer chopped with a roller was formed on the road surface. However, this method had a problem in that epoxy resin and fluorine-epoxy modified resin were affected by temperature, making it impossible to construct in the cold winter season, and it was not possible to work at night when there was a lot of moisture or dew due to the influence of humidity. In order to improve this problem, Korean Patent Registration No. 10-0804765 discloses a construction method of an anti-slip facility using a two-component material.

The light emitting devices 330 are mounted to be spaced apart from each other along the circumferential direction on the longitudinal section forming the outlet of the nozzle body 280 to emit light. A light emitting diode is applied to the light emitting device 330 . In this case, a beam vertically emitted from the light emitting device 330 may be used to guide the discharge boundary area.

The power supply control unit 320 is driven by the power generated by the generator 310 and controls the supply of the power generated by the generator 310 to the light emitting devices 330 .

A process of controlling the power supply to the light emitting device 330 of the power supply control unit 320 will be described with reference to FIG. 5 .

The power supply control unit 320 determines whether the power output from the generator 310 is less than or equal to the set lower limit reference power (step 410). When the power output from the generator 310 is less than or equal to the set lower limit reference power, all of the light emitting devices 330 are controlled to be turned off (step 420). Here, the lower limit of the reference power may be appropriately applied to the extent that compressed air supplied through the outdoor air supply pipe 170 is supplied to a degree that it is difficult to contribute to precisely discharging the coating film composition.

On the other hand, if the power output from the generator 310 is greater than the lower limit reference power, it is determined whether it is less than or equal to the intermediate reference power set higher than the lower limit reference power (step 430). Here, the intermediate reference power may be appropriately applied to the extent that compressed air supplied through the outdoor air supply pipe 170 is supplied to precisely discharge the coating film composition.

When it is determined in step 430 that the power output from the generator 310 is equal to or less than the intermediate reference power, a reference number of light emitting devices 330 set less than the total number of light emitting devices 330 are controlled to emit light. On the other hand, if the power output from the generator 310 in step 430 is higher than the intermediate reference power, all light emitting devices 330 are controlled to emit light (step 450).

Therefore, the operator can grasp the state of the compressed air supplied through the outdoor air supply pipe 170 from the number of light emitting elements 330, and visually determine the ejection area of the coating film composition from the light emitted from the light emitting element 330 It is possible to increase the work precision of coating film application.

On the other hand, although not shown, the nozzle body 180, 280 may be fixedly installed on a separate support bar to which the traveling cart 110 is fixed, of course.

It goes without saying that such a road coating film applicator may be used to apply a coating film on various road surfaces as well as to form an anti-slip coating film on a road of a vehicle on which a vehicle travels.

According to the road coating film application apparatus described above, it is possible to precisely apply the coating film, thereby supporting the formation of a uniform coating film thickness.
