Reliable and convenient bridge trunnion connecting method for small cutter suction dredger
The invention relates to a reliable and convenient bridge trunnion connecting method for a small cutter suction dredger. A main buoyancy tank is connected with a main bridge of a bridge system through a trunnion structure; the method comprises the steps that firstly, main buoyancy tank reinforcing structures are welded to the two corresponding sides, connected with a bridge system, of a main buoyancy tank respectively, and a main buoyancy tank sleeve is welded to each main buoyancy tank reinforcing structure; bridge frame reinforcing structures are welded to the two corresponding sides, connected with a main floating box, of a main bridge frame of the bridge frame system respectively, a bridge frame sleeve is welded to each bridge frame reinforcing structure, and a sliding bearing is installed in each bridge frame sleeve; a bearing end cover and a small-sized handle are sequentially welded at one end of the trunnion to form a combined body; and secondly, the bridge system is hoisted to the position of the main buoyancy tank through hoisting equipment, the combined body of the trunnions is inserted into the main buoyancy tank sleeve and the bridge sleeve and fixed through bolts, and bridge connection is completed. The device is easy and convenient to operate, convenient to use and install, high in reliability and easy to maintain, disassemble and assemble, the connecting strength is guaranteed, and the normal construction requirement of the ship is met.
本发明涉及一种可靠便捷的小型绞吸挖泥船桥架耳轴连接方法，主浮箱通过耳轴结构与桥架系统的主桥架连接；步骤一、在主浮箱与桥架系统连接对应的两侧分别焊接主浮箱加强结构，在每个主浮箱加强结构上焊接主浮箱套筒；在桥架系统的主桥架与主浮箱连接对应的两侧分别焊接桥架加强结构，在每个桥架加强结构上焊接桥架套筒，在桥架套筒内安装滑动轴承；在耳轴一端依次焊接轴承端盖和小型把手，组成组合体；步骤二、通过起吊设备将桥架系统吊至主浮箱处，将耳轴的组合体插入主浮箱套筒和桥架套筒内，并通过螺栓进行固定，完成桥架连接。本发明操作简便、使用安装方便、可靠性强、易于维护拆装，既保证连接强度，又满足船舶正常施工的要求。
