The invention discloses a nuclear island main system equipment hoisting method, which comprises the following steps that S1, when main system equipment is in a horizontal state, a main crane is connected with the head part of the main system equipment, and an auxiliary crane is connected with the tail part of the main system equipment; s2, a main crane lifts the head of the main system equipment, and an auxiliary crane is matched with the main crane until the main system equipment is converted into an upright state from a horizontal state; and S3, the connection between the auxiliary crane and the tail of the main system equipment is removed, and the main crane lifts the main system equipment to a mounting position. According to the nuclear island main system equipment hoisting method, hoisting of the main system equipment is achieved through cooperation of the two cranes, the installation technology and requirements are simple, the installation workload is small, operation is easy, and efficiency is improved; the problems that in a single-machine rotating method, a turnover support, a J-shaped support and the like are needed, the installation workload is large, the requirement for the installation technology is high, and the requirement for site arrangement is high are effectively solved, and the nuclear island main system equipment hoisting technology is optimized.

    本发明公开了一种核岛主系统设备吊装方法,包括以下步骤:S1、在主系统设备处于横卧状态下,将主力吊车连接主系统设备的头部,辅助吊车连接主系统设备的尾部;S2、主力吊车提升将主系统设备的头部吊起,辅助吊车配合所述主力吊车,直至将主系统设备从横卧状态转为直立状态;S3、拆除辅助吊车与主系统设备的尾部的连接,主力吊车将主系统设备起吊至安装位置。本发明的核岛主系统设备吊装方法,以双台吊机相配合实现主系统设备的吊装,安装技术及要求简单、安装工作量少、易操作且提高效率,有效解决单机旋转法中需要翻转支架、J型支架等及存在的安装工作量大、安装技术要求高、场地布置要求高等问题,优化了核岛主系统设备吊装工艺。
