Description

Paint supply device for non-slip road surface}

The present invention relates to a technology for preventing a vehicle from slipping on a road surface, and more particularly, a road surface anti-slip surface configured to form an anti-slip surface by spraying paint using an application roller equipped with a plurality of protruding pins. It is about paint dispensing equipment.

In general, on an inclined road surface or a section requiring a predetermined braking force, a function to prevent a safety accident of a running vehicle by suppressing a slip phenomenon of the road surface due to snow or rain is required.

Considering this, anti-skid materials are installed on downhill or curved roads to increase the friction coefficient between the vehicle tires and the road surface, thereby inducing drivers passing this area to slow down and keeping the vehicle balanced. Accidents can be prevented in advance.

In general, to prevent slipping on roads, aggregates such as silica sand, quartz, glass beads, bauxite, steel slugs, etc. are mixed with flooring paint such as thermoplastic resin, and then applied to the road surface using raker, spatula, etc., and then applied with a roller brush As a result, a concave-convex surface is formed on the road surface.

That is, the method using the roller brush uses a fixed pile equipped with fur, chemical fibers, natural fibers, etc. on the outside of the cylindrical core, and at the same time as the cylindrical core is rotated, the end of the pile presses the surface of the non-slip flooring material. to form a flattened and concave-convex surface.

However, these roller brushes are hardened quickly as the paint and aggregate aggregate on the pile, so the paint and aggregate stick to the pile and are not evenly distributed and not applied in a uniform thickness. is raised, and as the pile of the roller brush and the surface of the flooring continue to rub against each other in a state where the initially used flooring material is not aggregated, it is not formed with a certain roughness, so the aesthetics are not good and the anti-slip effect is reduced.

In addition, existing roller brushes have limitations in removing air bubbles inside the flooring and filling grooves or gaps on the road surface, resulting in defects such as falling off, cracking, and abrasion, and piles made of natural or synthetic fibers Since it is eliminated by the viscosity of the flooring material, the service life may be significantly reduced.

In relation to such a device for preventing slipping on the road surface, Korean Patent Registration No. 1404641 discloses a paint supply unit having a slit-shaped discharge part along the length direction, attached to the lower end of the discharge part of the paint supply unit to control the supply amount of paint Disclosed is a non-slip construction apparatus including a paint supply valve, a spraying unit installed at a distance from the lower part of the paint supply unit and spraying paint falling downward through the paint supply unit and the paint supply valve.

However, in this method, there is a disadvantage that the paint is not sprayed because an impeller having a plurality of holes perforated in a row is mounted in the cylindrical portion constituting the spraying unit, and a concave-convex surface for preventing slipping of the road surface can be formed. It contains functional problems that cannot be solved.

First, as an example related to the technical content of the present invention, the known technology disclosed in Registration Patent No. 1501091 will be described, and after deriving problems accordingly, the configuration and operational effects of the present invention will be described later.

As shown in FIGS. 1 to 3, the roller device 100 for forming anti-slip unevenness of the flooring material for application includes a body portion 10, a concavo-convex forming portion 20, a rotating shaft 30, and a grip portion 40. ) is composed of.

The flooring material (M) is applied to the surface of the target surface (K) requiring anti-skid function, such as a ramp, parking lot, pedestrian road, etc., and is used to prevent a pedestrian's fall or a traffic accident. , quartz, glass, steel slag, etc. are mixed and then applied to the target surface (K) using a raker, a spatula, or the like.

The flooring material M may include methyl methacrylate (hereinafter referred to as MMA), and may be used as an adhesive, a coating agent, and a binder for painting. When the flooring (M) mixed with MMA is applied to the target surface (K), the curing time is fast, so the control time on roads, etc. By penetrating, it is possible to improve the tightness between the aggregate and the target surface (K).

In addition, a non-slip concave-convex surface including a concave X and a convex portion Y is formed on the surface of the flooring MMA so that the MMA-mixed flooring M is tightly adhered to the target surface K and the non-slip effect is reinforced. can do. To this end, a roller device 100 for forming non-slip unevenness of a flooring material for application having an unevenness forming part 20 provided on the outer surface 13 of the body part 10 is provided.

On the upper side of the target surface K, a flooring material M mixed with MMA and aggregate is applied in a semi-solid state to prevent slipping of pedestrians or vehicles. And the body part 10 is seated on the upper side of the target surface (K) to which the flooring material (M) is applied. At this time, the body part 10 is composed of a cylindrical shape with a hollow part 11 formed therein so as to be rotated and transferred to the upper side of the target surface K.

In addition, when the body portion 10 is rotated and transported, a concave-convex forming portion 20 is formed on the outer surface of the body portion 10 so that a non-slip concave-convex surface can be formed by pressing the surface of the flooring material M in a semi-solid state. are provided In the concavo-convex portion 20, a plurality of pressing protrusions 21 extending in a columnar shape with a set length are arranged radially.

The pressing protrusion 21 includes an inner end 21a connected to the outer surface 13 of the body 10 and an outer end 21b that presses the flooring M, and a set length is extended between them. A side portion 21c is formed. The cross section of the inner end portion 21a and the cross section of the outer end portion 21b are formed in the same shape and size, so that the pressing protrusion 21 is formed in a prismatic or cylindrical shape extending with a uniform thickness.

Meanwhile, a hollow part 11 is formed in the body part 10 so that the rotating shaft 30 passes through the center. The rotating shaft 30 is connected by the inner surface 12 of the body portion 10 and the ball bearing 31 that mediate the body portion 10 to rotate around the rotating shaft 30 . At this time, the ball bearings 31 are provided at both ends of the body portion 10 to stably mediate the rotating shaft 30 and the inner surface 12 of the body portion 10 .

In addition, cover parts 15 are provided at both ends of the body part 10 to block the inflow of foreign substances into the hollow part 11 . Both ends of the rotating shaft 30 may protrude from the body 10 . To this end, a through hole through which both ends of the rotating shaft 30 are exposed to the outside is formed in the central portion of the cover part 15 .

Referring to FIG. 3, as the worker moves to the upper side of the target surface K on which the flooring M is applied while holding the grip part 40, the body part 10 is rotated around the rotational shaft 30, causing irregularities. The outer end portion 21b of the pressing protrusion 21 is inserted while pressing the flooring material M by the forming portion 20 .

That is, after one side 21d of the outer end of the pressing protrusion 21 penetrates into the flooring M first according to the direction of rotation of the body portion 10, the pressure protrusion 21 is moved by the load of the body portion 10. As the outer end 21b is inserted into the surface of the target surface K, a groove X corresponding to the shape of the outer end 21b of the pressure protrusion 21 is formed in the flooring M, and the pressure protrusion 21 The side portion 21c of the is formed with a convex portion Y that is slightly higher than the height to which the flooring material M is previously applied corresponding to the volume of the outer end portion 21b inserted.

In addition, when the pressing protrusion 21 comes out of the groove X by the rotation of the body portion 10, one side 21d of the outer end of the pressing protrusion 21 remains on the rim surface of the groove X. Since (M) is pushed toward the upper side of the convex portion (Y), the roughness of the concave-convex surface can be improved. In some cases, the body part 10 is immersed in the flooring material M so that the flooring material M sufficiently remains between the pressing protrusions 21 of the concavo-convex part 20, and then rotates on the target surface K. By doing so, it is also possible to work so that a non-slip concave-convex surface is formed at the same time as applying the flooring material (M).

In addition, a grip part 40 is connected to both ends of the rotating shaft 30 protruding from the body part 10, and the grip part 40 includes a handle part 41 and a connection part 42. At this time, the handle part 41 is connected vertically to the longitudinal direction of the rotating shaft 30, and at the same time, an adjusting part 41a is provided so that the length can be selectively adjusted in response to the height of the operator.

The handle part 41 is composed of at least two or more hollow pipes, and the end of one pipe is inserted into the hollow of the other pipe and connected thereto. A plurality of through-holes are formed along the longitudinal direction at the portion where the pipes overlap, and the length of the handle portion 41 can be selectively adjusted by fastening the restraining member.

The handle part 41 and the body part 10 are bound by a connection part 42, and the connection part 42 and the fastening part 42a of the rotating shaft 30 are permanently fixed by welding or the like, and the grip part ( 40) and the body portion 10 may be bolted to be selectively separated.

By the way, in the roller device for forming non-slip unevenness of the flooring material for application having such a structure, the outer end 21b of the pressing protrusion 21 is formed in a semi-solid form by the load of the body part 10 and the unevenness forming part 20. A groove (X) corresponding to the shape of the outer end (21b) is formed by pressing the upper surface of the flooring (M) in the state.

However, when the pressure projection 21 comes out of the groove X, it pushes the flooring M remaining on the edge surface to the upper side of the convex part Y, as well as the groove before the semi-solid flooring M is solidified. Since it flows down to (X), a sufficient non-slip effect cannot be expected as the boundary of the non-slip concave-convex surface becomes unclear, and after applying the flooring material (M), the roller device 100 is used again to form the non-slip concave-convex surface. There is discomfort.

In addition, the configuration of the body portion 10 constituting the roller device 100 is generally complicated, and after the work is completed, between the pressing protrusions 21 of the concave-convex portion 20, Since the residue is attached and completely solidified, it is difficult to remove it, such as having to wash it through strong chemical treatment.
