ABSTRACT

Since the construction efficiency of the cutter suction dredger is closely related to the performance of the cutter head, in order to improve the construction efficiency of the cutter suction dredger, this paper refers to the cylindrical coordinate method to locate the cutter holder and the teeth. By designing and manufacturing a simple device, and selecting three positioning points on the adapter, the mounting position of the cutter holder is determined according to the cylindrical coordinates of the three positioning points of the adapter. In the actual production and construction, the problem of installation and positioning of the reamer teeth and the tooth holder is effectively solved.
