Drill device for installating of road safety features and road drilling machine having the same and construction method of road safety features

摘要

The present invention relates to a drilling drill device for installing road safety facilities with adjustable spacing, a road drilling machine including the same, and a construction method of a road safety facility, and more particularly, a vertical bar and an upper portion of the vertical bar so that the lower end of the vertical bar is non-contact with the ground. The elevating jig on which the is mounted, and both ends of the elevating jig are slidingly coupled, vertically spaced apart from each other, and the corresponding elevating guide member, which is perpendicular to the vertical bar, and is rotatably coupled horizontally to the vertical bar. A drill chuck in which at least two screw bolts and a drill bit for drilling the road surface to a certain depth in order to form a hole into the road surface into which an anchor bolt for fixing and installing road safety facilities on the road is detachably mounted, The driving means for providing rotational force to the drill chuck and the driving means are mounted, and a through hole through which the screw bolt horizontally penetrates is formed, and is provided at the end of the screw bolt and the drill holder that is helically coupled to the outer diameter of the screw bolt to reverse the screw bolt It includes a rotating means for rotating, and when the screw bolt is rotated forward and backward by the rotating means, the drill holder relates to a drilling drill device for installation of road safety facilities capable of adjusting intervals, characterized in that the drill holder is linearly reciprocated in the longitudinal direction of the screw bolt. . According to the present invention, it is possible to easily adjust the distance between the perforations formed on the road surface with at least two or more fixing the posts of the road safety facility.
