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 in more detail, a road surface configured to form a non-slip surface by spraying paint using an application roller equipped with a plurality of protruding pins It relates to anti-skid paint installation equipment.

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

Considering these points, by constructing an anti-skid material on the downhill or curved road of the road to increase the coefficient of friction between the vehicle tire and the road surface, it induces the driver passing through this area to be slowed down and maintains the vehicle balance. Accidents can be prevented in advance.

In general, to prevent the road from slipping, after mixing aggregates such as silica sand, quartz, bead, bauxite, steel slag, etc. to a floor coating such as thermoplastic resin, apply it to the road surface using a raker or a spatula, and use a roller brush. As a result, an uneven surface is formed on the road surface.

In other words, the method using a roller brush uses a fixed pile equipped with fur, chemical fiber, natural fiber, etc. on the outside of the cylindrical core, and the end of the pile presses the surface of the non-slip flooring material while rotating the cylindrical core. To form a flattened and uneven surface.

However, due to the phenomenon that the paint and aggregate are rapidly hardened as the paint and aggregate on the pile are aggregated, the paint and aggregate adhere to the pile and are not distributed evenly and are not applied in a uniform thickness. As the first floor material is not agglomerated, the pile of the roller brush and the surface of the floor material are not formed with a certain roughness as the pile and the surface of the floor material continue to rub, so the appearance is not good and the anti-slip effect is poor.

In addition, in the case of the existing roller brush, there is a limit to removing air bubbles inside the floor material and filling grooves or gaps on the road surface, resulting in defects such as dropping, cracking, abrasion, etc., and piles made of natural or synthetic fibers Since it is dropped due to the viscosity of the flooring material, the service life may be significantly reduced.

With regard to such a device for preventing slipping on the road surface, Korean Patent No. 1404641 discloses a paint supply unit in which a discharge unit is formed in a slit shape along the length direction, and is attached to the lower end of the discharge unit of the paint supply unit to control the supply amount of paint. Disclosed is a non-slip construction apparatus comprising a paint supply valve, a spraying unit that is spaced apart from the lower part of the paint supply unit and sprays and applies the paint falling downward through the paint supply unit and the paint supply valve.

However, in this method, there is a disadvantage that paint is not scattered because a plurality of holes are perforated in a row in the cylindrical portion constituting the spraying part, and it is also possible to form an uneven surface to prevent slipping of the road surface. It implies a functional problem that it cannot.

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

As shown in Figs. 1 to 3, the roller device 100 for forming the non-slip irregularities of the flooring material for application includes the body part 10, the uneven forming part 20 and the rotation shaft 30, and the grip part 40 ).

Flooring (M) is applied to the surface of the target surface (K) that requires anti-skid function, such as slopes, parking lots, pedestrian roads, etc., and is used to prevent falls of pedestrians or traffic accidents of vehicles. After mixing aggregates such as, quartz, glass, steel slag, etc., apply it to the target surface (K) using a raker or spatula.

The flooring (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 applying the MMA-mixed flooring material (M) on the target surface (K), the curing time is quick and the control time for roads is shortened to minimize discomfort, and the adhesion is excellent so that it is deeply applied to the target surface (K). Penetration can improve the tightness between the aggregate and the target surface (K).

In addition, a non-slip uneven surface including grooves (X) and convex portions (Y) is formed on the surface of the floor material (M) so that the floor material (M) mixed with MMA is firmly 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 and convexities of the coating flooring material provided with the uneven forming portion 20 on the outer surface 13 of the body 10 is provided.

On the upper side of the target surface K, a floor material M mixed with MMA and aggregate is applied in a semi-solid state to prevent slipping of pedestrians or vehicles. And the body portion 10 is seated above the target surface (K) on which the floor material (M) is applied. At this time, the body portion 10 is configured in a cylindrical shape with a hollow portion 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 transferred, the uneven forming portion 20 is formed on the outer surface of the body portion 10 so that a non-slip uneven surface can be formed by pressing the surface of the semi-solid floor material M. It is equipped. In the uneven forming portion 20, a plurality of pressing protrusions 21 extending in a columnar shape of a set length are radially aligned.

The pressing protrusion 21 includes an inner end 21a connected to the outer surface 13 of the body 10 and an outer end 21b for pressing the floor material M, and extending to a set length between them The 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 to a uniform thickness.

On the other hand, the body portion 10 is formed with a hollow portion 11 is configured so that the rotation shaft 30 passes through the center. The rotation shaft 30 is connected by a ball bearing 31 that is mediated with the inner surface 12 of the body 10 so that the body 10 rotates around the rotation shaft 30. At this time, the ball bearings 31 are provided at both ends of the body portion 10 so as to stably mediate the hwajeon shaft 30 and the inner surface 12 of the body portion 10.

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

Referring to FIG. 3, as the operator moves to the upper side of the target surface K on which the flooring material M is applied while holding the grip part 40, the body part 10 rotates around the rotation shaft 30, and The outer end portion (21b) of the pressing projection (21) by the forming portion (20) is inserted while pressing the floor material (M).

That is, according to the rotation direction of the body portion 10, one side (21d) of the outer end of the pressing protrusion 21 first digs into the floor material (M), and then the pressure of the pressure protrusion 21 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 pressing projection (21) is formed in the flooring (M), and the pressing projection (21) The side portion (21c) of the outer end (21b) corresponding to the inserted volume is formed with a convex portion (Y) slightly raised than the height of the existing flooring (M) is applied.

And, when the pressing protrusion 21 comes out from the groove (X) by rotation of the body portion (10), one side (21d) of the outer end of the pressing protrusion (21) remains on the edge of the groove (X) Since (M) is pushed upward of the convex portion (Y), the roughness of the uneven surface can be improved. In some cases, the body part 10 is settled on the floor material M so that the floor material M remains sufficiently between each pressing protrusion 21 of the uneven forming part 20 and then rotated from the target surface K By doing so, the floor material M may be applied and a non-slip uneven surface may be formed at the same time.

In addition, grip portions 40 are connected to both ends of the rotating shaft 30 protruding from the body portion 10, and the grip portion 40 includes a handle portion 41 and a connection portion 42. At this time, the handle part 41 is provided with an adjustment part 41a so as to be connected vertically to the longitudinal direction of the rotation shaft 30 and selectively adjust the length in response to the height of the worker.

The handle part 41 is made of at least two or more hollow pipes, and an end of one pipe is inserted into the hollow inside of the other pipe to be connected. A plurality of through-holes are formed along the lengthwise direction in the portion where the pipes overlap, and the length of the handle part 41 can be selectively adjusted as the restraining member is fastened.

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 can be fastened with bolts so as to be selectively separated.

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

However, when the pressing protrusion 21 comes out of the groove (X), the floor material (M) remaining on the edge surface is pushed to the upper side of the convex part (Y), as well as the groove before the semi-solid floor material (M) is solidified. As it flows down to (X), a sufficient non-slip effect cannot be expected as the boundary of the non-slip uneven surface becomes unclear, and the non-slip uneven surface must be formed again using the roller device 100 after applying the floor material (M) There is a discomfort of the top.

In addition, the overall configuration of the body portion 10 constituting the roller device 100 is complex, and after the work is completed, the bottom material (M) buried between the pressing protrusions 21 of the uneven forming portion 20 Since the residue adheres and is completely solidified, there is a considerable difficulty in removing work such as having to be cleaned through strong chemical treatment.
