The invention relates to the technical field of desilting equipment, in particular to a desilting crane below a wharf, the interior of a base is of a hollow structure, and a bearing seat is embedded in a top opening of the base; the rotary gear is mounted on the rotary main shaft and arranged in the base, the lower end of the rotary main shaft is rotationally mounted at the bottom of the base through a conical bearing, and the rotary main shaft is rotationally connected with the bearing seat through the conical bearing; the rotary rack is in meshing drive with the rotary gear, the rotary rack is movably arranged in the oil cylinder barrel, and the two ends of the oil cylinder barrel penetrate through the base and then are provided with end covers with oil way through holes; and the rotating table is sleeved on the rotating main shaft through a main shaft mounting seat on a bottom plate of the rotating table. A variable-amplitude oil cylinder is matched with a hydraulic rack oil cylinder (a rotation rack, an oil cylinder barrel, a rotation gear and the like), so that the lifting rotation of the arm support is realized, and the adjustment of various working states is realized.
一种码头下方清淤起重机,本发明涉及清淤设备技术领域,底座内部为空心结构,其顶部开口中嵌设有轴承座;回转齿轮安装在回转主轴上,且设置与底座内,回转主轴的下端利用圆锥轴承转动安装在底座底部,且回转主轴利用圆锥轴承与轴承座转动连接;回转齿条与回转齿轮啮合驱动,且回转齿条活动设置于油缸筒内,油缸筒的两端穿过底座后,均安装有带油路通孔的端盖;转动台利用其底板上的主轴安装座套接安装在回转主轴上。利用变幅油缸配合液压齿条油缸(回转齿条、油缸筒、回转齿轮等),实现了臂架的起升一回转,实现了多种工作状态的调节。
