Description

Spraying equipment for lane painting{SPRAYING DEVICE FOR PAINTING TRAFFIC LANE}

The present invention relates to a facility for painting marking lines partitioned on a road surface of a roadway, and more particularly, it is possible to more efficiently eject materials for painting such as paint as well as glass beads. It relates to the spraying equipment for painting the lane configured to be.

In general roads, order is maintained by marking the road surface for the purpose of warning or guidance on traffic, and in particular, various markings are displayed so that vehicles can pass according to established rules through lane painting according to safety.

That is, in the case of a lane, it is displayed in the center of the road and is largely divided into a center line for separating the driving direction or a driving line for separating the lane, and in addition, shoulders, crosswalks, and parking lines are painted.

As for the painting of lanes, the lane was painted directly on the road using manual marking equipment, but in recent years, various equipments that can automatically paint lanes have been proposed because it causes a prolonged construction period due to the lack of speed of work progress. Has become.

With regard to such equipment for painting lanes on a road surface, publications such as Patent Nos. 0346415 and 0346416 disclose a technology related to a lane painting apparatus using a two-component paint. Since this device is configured to paint lanes while spraying through a spray gun after mixing the main material and hardener in a blender, etc., it is very difficult for continuous painting because the paint hardens inside the spray gun by the hardener when used for a long time. Will result.

In addition, Korean Patent Publication No. 2010-0056591 discloses a paint spray nozzle for a painted vehicle, but in this case, as the paint sprayed by compressed air is diffused and dispersed widely, the thickness applied to the lane is thin and the paint is outside the lane width. Spreading occurs.

On the other hand, when painting road marking lines, glass powder in the form of fine particles that can reflect light (usually referred to as "bead") is adsorbed on the upper surface of the paint on the marking line to reflect the light of the vehicle's headlights or streetlights to be clearly displayed. A means of doing this is proposed.

That is, in the case of the ``bead spraying device for lane painters'' disclosed in Korean Patent Nos.1389296 or 1389297, it is difficult to match the rotational speed of the rotary valve and the impeller, so that the bead cannot be uniformly supplied to the receiving part between the blades. There is a disadvantage in that the amount of bead sprayed in the lane is not constant, and the opening in the lower part of the case is formed wide, so that the bead is scattered to parts other than the painted part, which is wasted.

In general road marking equipment, as the fusion-type paint is discharged in a relatively narrow width, it is useful to paint road marking lines such as ordinary lanes, but it is useful to paint relatively wide road surface marking lines such as crosswalk marking lines. In order to do so, first, the painting equipment must be painted by reciprocating 3-4 times while adjusting the painted part and the joint part to match.

Therefore, not only takes considerable labor and time for the painting work, but also because the road marking lines overlap each other and partially protrude, it is affected by vehicle driving, and there is an empty space that is not painted, so that the work must be performed again. Regardless of the problem, the problem is that it cannot be applied evenly.

Patent Publication No. 2010-0056591 (published on May 28, 2010)-Paint spray nozzle for fusion-type spray-painted vehicles. Patent Publication No. 2013-0011576 (published on Jan. 30, 2013)-Lane painting device for crosswalks. Registered Patent No. 0400820 (registered on September 24, 2003)-Lane applicator. Registered Patent No. 1524746 (registered on May 26, 2015)-A painting module for a wide variable road marking equipment capable of painting a crosswalk of 5 to 45 cm width. Registered Patent No. 1595462 (registered on February 12, 2016)-Lane, crosswalk, anti-skid painting device for letter symbols and lane painting method using the same.
