The invention provides a modularized combined type special hoisting and transferring tool for nuclear maintenance. The modularized combined type special hoisting and transferring tool comprises a hoisting box body, a transferring barrel section, a middle barrel section and a receiving barrel section. A hoisting machine is arranged in the hoisting box body, and the hoisting machine hoists and lifts nuclear-related equipment, parts and pipeline accessories which need to be transferred out of a cabin through a hoisting rope; the transfer cylinder section, the middle cylinder section and the receiving cylinder section are made of shielding materials and are connected through bolts, and the end faces of the adjacent cylinder sections are opened and used for building a maintenance hoisting channel; the receiving cylinder section is provided with a cylinder section cabin door used for receiving nuclear equipment, components and pipeline accessories. According to the technical scheme, when nuclear equipment, parts, pipeline accessories and the like in a ship nuclear power device reactor cabin need to be taken out of the cabin for maintenance or replacement, receiving, hoisting and transferring tools are provided, the space occupancy rate of maintenance operation is reduced, it is ensured that radioactive substances are effectively contained, and the service life of the nuclear power device is prolonged. Therefore, the marine nuclear power device has higher safety and reliability in the nuclear maintenance out-of-cabin process.
本发明提供一种模块化组合式涉核维修的专用吊装转运工具,包括:吊装箱体、转运筒段、中间筒段和接收筒段。吊装箱体内置吊装机,吊装机通过吊装绳吊装起降需要出舱转运的涉核设备、部件和管路附件;转运筒段、中间筒段、接收筒段由屏蔽材料制造,转运筒段、中间筒段及接收筒段之间采用螺栓连接,相邻筒段端面打开,用于建立维修吊装通道;接收筒段设置筒段舱门,用于接收涉核设备、部件和管路附件。本发明技术方案,在船用核动力装置堆舱内涉核设备、部件、管路附件等需要出舱维修或更换时,提供接收、吊装、转运用工具,在减少维修作业空间占有率的同时,确保放射性物质有效包容,使船用核动力装置涉核维修出舱流程具有更高的安全性和可靠性。
