Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a surface treatment device for forming a large number of irregularities on the surface of a pavement such as concrete or asphalt pavement.

<Prior art> On concrete-paved roads, etc., the frictional resistance of the pavement surface is small immediately after concrete construction or several years have passed since construction, and this can easily cause cars to skid. The bumps are formed to increase frictional resistance and improve vehicle running safety.

As a conventional example of such surface treatment of pavements, there is a system in which a heavy and small surface treatment device body that intermittently collides with the surface of the pavement is attached to a handcart. Then, an operator manipulates a handcart to move the main body of the surface treatment apparatus while forming a large number of irregularities on the surface of the pavement.

<Problems to be solved by the invention> However, in such conventional surface treatment equipment, the heavy and small surface treatment equipment body is attached to a handcart, so it cannot be used on pavements such as wide concrete paved roads. In order to form irregularities over the entire surface, the irregularities had to be created by moving a handcart up and down the road. For this reason, working efficiency was reduced and it was difficult to form irregularities substantially uniformly over the entire surface of the pavement. Also, because the device is heavy,
Operators were highly fatigued and there were also safety issues.

The present invention was developed in view of the above-mentioned circumstances, and aims to provide a surface treatment device for pavements that can improve work efficiency and form unevenness substantially uniformly over the entire surface of the pavement. do.

<Means for Solving the Problems> For this reason, the present invention provides a plurality of surface treatment device bodies that form a large number of irregularities on the surface of a pavement body, which are arranged at predetermined intervals in the longitudinal direction of the vehicle, and a first moving device that is attached to each of the device bodies and moves each surface treatment device body independently of each other in the width direction; and a first moving device that is attached to each of the surface treatment device bodies and moves all of the surface treatment device bodies in the width direction of the vehicle; and a second moving device that moves the vehicle substantially simultaneously in the same direction.

<Function> Then, the first moving device moves the plurality of surface treatment device bodies to change the construction width, and the second
The main body of the surface treatment apparatus is moved in the width direction by a moving device to form a large number of irregularities on the surface of the pavement. Further, if necessary, one of the second moving devices is operated to form irregularities on the pavement surface only by the corresponding surface treatment device main body.

A concrete pavement body 1 is attached to the lower end surface of these bit bodies 16.
A plurality of bits (not shown) are provided for biting into the hole 5 by a predetermined amount.

A plate-shaped second moving member 17 extending in the width direction of the vehicle is attached to the second rail 8 so as to be freely movable in the width direction of the vehicle. This second moving member 17 has a third
