The invention relates to a cutter suction dredger, in particular to a cutter suction dredger positioning mechanism and a positioning method.The cutter suction dredger positioning mechanism comprises an open hole which is formed in a dredger body and is of a cylindrical structure on the whole, a barrel structure is arranged in the open hole, and an annular mounting groove is formed in the inner wall of the lower end of the barrel structure; a guide groove which is communicated with the annular mounting groove and extends upwards in the length direction of the barrel structure is formed above the annular mounting groove, an annular mounting frame is further arranged in the barrel structure and used for mounting a guide pulley, and a supporting block is arranged on the outer circle of the annular mounting frame. The supporting blocks and the guide grooves form sliding guide fit so that the annular installation frame can move to the annular installation groove, and after the supporting blocks rotate by a certain angle, the supporting blocks and the groove walls of the two sides of the annular installation groove form limiting fit. The problems that in the prior art, a barrel structure needs to be overall lifted out to guarantee the maintenance space, and hoisting is difficult due to the fact that the overall weight of the barrel structure is large are solved.

    本发明涉及绞吸式挖泥船,特别涉及一种绞吸式挖泥船的定位机构和定位方法,包括设置在船体内、整体呈圆柱形结构的开孔,开孔内设置有筒体结构,所述筒体结构的下端内壁设有环形安装槽,环形安装槽的上方设有相连通且沿筒体结构的长度方向向上延伸的导槽,所述筒体结构内还设有一环形安装架用于安装导向滑轮,所述环形安装架的外圆设有支撑块,所述支撑块与导槽构成滑动导向配合使所述环形安装架移动至环形安装槽处,且在旋转一定角度后,所述支撑块与所述环形安装槽的两侧槽壁构成限位配合;本发明解决了现有技术中需要将筒体结构整体提出来保证维护空间,而筒体结构整体重量较大导致起吊困难的问题。
