ROAD SURFACE CUTTING APPARATUS
PROBLEM TO BE SOLVED: To more improve followability of a road surface cutting machine to change of a road surface to be cut.SOLUTION: A road surface cutting device comprises: a road surface cutting machine 3 which is provided to a vehicle and cuts a road surface as the vehicle travels; an actuator 4 which elevates and lowers the road surface cutting machine 3; cutting depth detection parts 19Aa, 19Ba which detect a road surface depth of cutting by the road surface cutting machine 3; and an elevation control part 19 which controls the actuator 4 so as to make smaller deviations between detection values of the cutting depth detection parts 19Aa, 19Ba and a set target depth H0 of cutting. The elevation control part 19 has an operation speed ratio setting part 19C which sets an operation speed ratio k of the actuator 4 larger when a traveling speed is slow than when the traveling speed is fast.SELECTED DRAWING: Figure 1
【課題】切削する路面変化に対する路面切削機の追従性をより向上させる。【解決手段】路面切削装置は、車両に設けられて上記車両の走行に伴い路面を切削する路面切削機３と、路面切削機３を昇降するアクチュエータ４と、路面切削機３により切削される路面深さを検出する切削深さ検出部１９Ａａ、１９Ｂａと、切削深さ検出部１９Ａａ、１９Ｂａの検出値と設定した目標切削深さＨ０との偏差が小さくなるようにアクチュエータ４を制御する昇降制御部１９と、を備える。昇降制御部１９は、走行速度が遅い場合、走行速度が速い場合に比べて、アクチュエータ４の作動速度比ｋを大きく設定する作動速度比設定部１９Ｃを有する。【選択図】 図１
