Wheel rail type bush hammer and cement concrete surface bush hammer method
The invention relates to the technical field of road and bridge engineering, and especially relates to a wheel rail type bush hammer and a cement concrete surface bush hammer method. The wheel rail type bush hammer comprises a support, a wheel rail and a scabbling mechanism, rolling wheels are installed on the support, and the scabbling mechanism is installed on the support; the scabbling mechanism comprises a crankshaft, a scabbling knife and a locking and resetting mechanism, the scabbling knife is mounted on a connecting rod journal of the crankshaft, and the crankshaft drives the scabblingknife to scabble a concrete surface when rotating; the locking and resetting mechanism comprises a locking pin and an arc-shaped groove; the locking pin and the arc-shaped groove are separately arranged on the side wall of the crankshaft arm and the side wall of the scabbling knife; the groove bottom surface of the arc-shaped groove is an inclined surface or an arc-shaped surface which is gradually lifted from front to back; and a concave portion is arranged at the bottom of the starting end of the arc-shaped groove, the rear end of the locking pin abuts against an elastic component, the front end of the locking pin is inserted into the concave portion to lock the scabbling knife, the front end of the locking pin makes contact with the side wall of the concave portion, and at least one ofthe contact faces of the front end of the locking pin and the concave portion is a slope face. The wheel rail type bush hammer is high in construction efficiency, deep in scabbling point and good inoperation stability.
轮轨式凿毛机及水泥混凝土面凿毛方法，涉及路桥工程技术领域，前述轮轨式凿毛机包括支架、轮轨和凿毛机构，支架安装有滚轮，凿毛机构安装在支架上；凿毛机构包括曲轴、锤刀以及锁止与复位机构，锤刀安装在曲轴的连杆轴颈上，曲轴转动时带动锤刀凿击混凝土面；锁止与复位机构包括锁止销以及弧形槽，锁止销和弧形槽分开设置在曲轴臂的侧壁以及锤刀的侧壁上，弧形槽的槽底面为一由前往后逐渐抬升的斜面或弧面，在弧形槽起始端的槽底设有一凹陷部，锁止销的后端抵靠住一弹性部件，锁止销前端插入凹陷部中将锤刀锁止，锁止销前端与凹陷部的侧壁接触并且在二者的接触面中至少有一个接触面为坡面。该轮轨式凿毛机施工效率高、凿点深且运行稳定好。
