Description

The painting device for a concavoconvex type the road surface mark}

The present invention relates to an apparatus for painting a protruding lane on a road surface, and more particularly, it is possible to selectively paint a scattering pattern lane and a water droplet pattern lane among the projecting lanes on the road surface with a single device as needed. It relates to a protruding lane painting device for the road surface.

In general, the painting of the road surface includes not only markings such as lanes, but also coloring the road, and is usually constructed using a painting device. The raw materials used for road markings are paints or two-component paints, that is, paints obtained by mixing acrylic resin with a curing agent, thermoplastic resins, etc., and mixing is performed by a stirrer provided inside the raw material container. And, in recent years, protruding lanes have been proposed to ensure visibility of road signs during day and night and rain, and to secure braking force and prevent slippage of vehicle driving due to aquaplaning.

3 and 7 show the lanes of the scattering pattern and the lanes of the droplet pattern among the conventional protruding lanes, and the lanes of the scattering pattern are mounted on an electric wagon as shown in FIGS. , and the water droplet pattern lane is mounted on the vehicle as shown in FIGS. 4 to 6 to perform the operation. As described above, in the related art, a scattering pattern protruding lane painting device and a water droplet pattern protruding lane painting device are separately provided.

Therefore, in the prior art, in order to perform a lane painting work by simultaneously performing a scattering pattern lane and a water droplet pattern lane at the same time or to meet the selective needs and conditions of the client, a scattering pattern lane painting device and a water droplet pattern lane should be used by a contractor. All of the painting devices have to be provided, which causes a decrease in economic feasibility due to the cost burden on the contractor, and each device is bulky and complicated in structure, making it difficult to store and manage, and it must be installed in the vehicle because it is not compatible with each other. In the case of a water droplet-shaped painting device for which painting work is performed, there was a problem that painting work was impossible in a narrow space where it was difficult to enter a vehicle.

On the other hand, the operator periodically performs a cleaning operation to remove the raw material being cured inside the device during the painting operation. This cleaning operation is to prevent in advance that the hole through which the raw material is discharged is clogged by the hardening raw material and thus not being painted. They disassemble one by one, remove and wash the hardened raw materials using thinner, etc., and then reassemble and install them on wagons and vehicles to perform painting work repeatedly. In general, washing work is performed every 30 minutes during the painting work, so the work is cumbersome and inconvenient, and time was wasted unnecessarily due to the washing work.

The raw material discharge hole 112 is formed in plurality at intervals along the longitudinal direction of the bottom surface of the manifold 110, but it is more preferable to form the raw material discharge hole 112 in two rows alternating before and after the non-slip side More advantageously, the raw material supply hole 114 and the air supply hole 113 communicate with the raw material discharge hole 112 on the rear and upper surfaces of the manifold 110 according to the number of the raw material discharge holes 112, respectively. A plurality of folds 110 are formed along the longitudinal direction.

The raw material supply unit 120 includes a raw material cylinder 121 , a raw material supply line 122 , a transfer screw 123 , and a valve A 124 installed on the raw material supply line 122 .

Raw materials are supplied to each raw material supply hole 114 of

In the present invention configured as described above, first, the raw material inside the raw material cylinder 121 is supplied into the raw material supply hole 114 of the manifold 110 by the driving of the transfer screw 123 , and the raw material supply hole 114 inside of the raw material is pushed and reaches the middle of the air supply hole 113 and the raw material discharge hole 112 communicating vertically. At this time, the raw material is continuously discharged through the raw material discharge hole 112 by the vertical downward pressure of the compressed air supplied through the air supply hole 113, so that the raw material is protruded on the road surface as shown in FIG. It will be possible to indicate the lane of the pattern. At this time, the valve B 133 on the air supply line 132 connected to the air supply hole 113 of the manifold 110 maintains the normally open state, and when the road marking operation is completed, the transfer screw 123 stops working and Valve B 133 is closed.
