Description

[Detailed Description of the Invention] The present invention relates to a road sign forming vehicle that excavates a road, embeds road sign material in the excavated portion, and forms road signs all at once.

Conventionally, the easiest way to display road signs on roads was to paint road sign materials on the road surface, but with this method, the road sign parts were subject to wear and tear due to vehicle traffic. However, it was inevitable that it would soon disappear. Therefore, as shown in Figure 1, by excavating the road, embedding road sign material in the excavated area, and making the surface part of the road sign material flat like the road surface, the road sign can be used for vehicle traffic. Efforts were being made to prevent loss due to this. However, in order to obtain a road sign as shown in FIG. 1, the process of excavating the road and the process of embedding the road sign material and flattening the surface have been performed separately. For this reason, performing separate processes is itself complicated, and if the time between the road excavation process and the display material embedding and surface treatment processes is long, the road may be left in the excavated state. The inconvenience of being left abandoned and unable for vehicles to pass through was inevitable.

The present invention aims to overcome these points. Below, the side view of Figure 2 and the side view of Figure 3.
The explanation will be given along the bottom view of the figure.

The features of the material of the present invention are that in the lower part of the vehicle body, from the front in the direction of travel, there is a temperature control device 21, a watering pipe 231, a rotary drum for excavation 22, a dust suction pipe 241, a marking material dropping pipe 251, and a road marking material. A working section is provided by sequentially arranging flat trowels 26 that slide on the surface portion.

That is, all of the working parts for carrying out the process operations necessary to excavate the road, embed the marking material therein, and level the surface of the marking material are all provided under the vehicle body.

The second feature of the configuration is that the excavating rotary drum 22 is attached to a variable chassis 3 in which the vertical position of the excavating drum 22 can be adjusted at the bottom of the vehicle body, and the distance of the excavating rotary drum 22 from the road surface can be adjusted. be.

The third feature of the configuration is that a water tank 23 is provided on the vehicle body above the watering pipe 231 to send water to it.
2. Above the dust suction pipe 241, there is a dust suction tank 242 through which dust is inhaled, a sign material tank 252 that communicates with the sign material drop pipe 251 from above and stores sign materials, and a sign material tank 252.
A pressurizing machine 253 is provided to force-feed the marking material inside through the marking material dropping pipe 251 and drop it.

The operation of the road sign forming vehicle according to the present invention will be explained below.

In the working section 2 provided at the lower part of the chassis 1 of the vehicle body, a temperature regulator 21 heats or cools the road surface to bring it to the most suitable temperature for excavating the road surface. Excavation of the road surface is performed by a rotary excavation drum 22. In addition, the second
In FIG. 3, a case is shown in which three combinations are provided by sequentially providing the watering pipe 231 and the rotating drum 22 from the front side in the direction of movement of the vehicle body, but this number is particularly limited. It's not a thing.
In the vehicle of the present invention, the working unit 2 moves along with the movement of the vehicle body, so a rotating drum system is most conveniently used as a tool for excavating roads.

Water is sprinkled on the road surface by the watering pipe 231 before the rotary excavation drum 22 excavates the road due to the friction between the rotary drum 22 and the road surface.
This is to prevent the rotating drum 22 from heating up.

The materials such as asphalt constituting the road excavated by the rotating drum 22 are crushed by the rotating drum 22 and turned into dust, which is sucked into the dust suction tank 242 through the dust suction pipe 241. Ru. Dust suction tank 242
Possible methods include suction using a vacuum and absorption using a suction pump.
These methods are not particularly limited.

After excavating the road in this way and inhaling the materials that make up the road, the marking material stored in the marking material tank 252 is forced downward by the pressurizer 253 and falls through the marking material drop pipe 251. Then, it will be poured into the excavated area.

Next, the flat trowel 26 slides on the upper surface of the marking material poured in this way to flatten the surface of the marking material.

The side shape of the flat trowel 26 is required to have a surface parallel to the road surface. In addition, when sliding on the surface of the marking material while pressing the marking material, use the flat trowel 2.
It is preferable to interpose an elastic member such as a spring or compressed air in the portion where the 6 is attached.

On the other hand, the excavating rotary drum 22 is attached to a variable chassis whose height is freely adjustable, thereby making it possible to freely adjust the depth of excavation.

In the vehicle of the present invention, the chassis 1 itself of the vehicle body is moving, so as the vehicle body moves, a road sign with embedded marking material is immediately formed. Moreover, the water injected from the water tank 22 to prevent the excavation rotary drum from heating up also helps in adhering the marking material to the bottom and side surfaces of the excavated portion of the road, making it easier than conventional excavated marking materials. It is convenient because there is no need to re-inject water when embedding it in the part.

Incidentally, if a nozzle for spraying glass beads for retroreflection is provided after the flat trowel 26 and the glass beads are sprayed, it becomes possible to automatically scatter the glass beads. If the car of this invention is driven straight, a straight road sign will be obtained, but if a curved road sign is to be formed, such a curved line must be drawn in advance. , if the car of the present invention is driven along these lines, a road sign with the planned curved shape will be formed.

As described above, the present invention makes it possible to make excavation-type road markings extremely efficiently and in a short time, and the injected water is used not only to prevent the excavation rotary drum from heating, but also to be used as marking material. It can also be used to bond to excavated surfaces, greatly increasing work efficiency.
