S1.2、将主力吊车通过第一吊具连接第一吊接件，将辅助吊车通过第二吊具连接第二吊接件。
其中，第一吊具和第一吊接件的连接为活动连接，以使得在主力吊车通过第一吊具吊起第一吊接件时，第一吊接件可相对第一吊具转动。同理，第二吊具和第二吊接件的连接为活动，第二吊接件可相对的第二吊具转动。
为使主系统设备与地面之间具有安全翻转距离，后续主系统设备的头部被吊起翻转过程中，主系统设备的尾部及其上的第二吊接件始终不与地面接触，在主力吊车和辅助吊车分别连接主系统设备的头部和尾部后，主力吊车和辅助吊车同时提升，将主系统设备水平吊起至预定高度。该预定高度无需太高，具体可根据第二吊接件在尾部所在位置及其尺寸等决定。
S2、主力吊车提升将主系统设备的头部吊起，辅助吊车配合主力吊车，直至将主系统设备从横卧状态转为直立状态(铅垂状态)。
该步骤中，在主力吊车将主系统设备的头部吊起后，辅助吊车将主系统设备的尾部向主系统设备的头部所在方向进行递送。在递送过程中，主系统 设备从横卧状态逐渐向直立状态翻转。其中，第一吊具与主系统设备的轴线从相对垂直逐渐变为相平行；第二吊具从垂直主系统设备的轴线逐渐变相对主系统设备的轴线倾斜。
或者，主力吊车提升将主系统设备的头部吊起后，将头部向主系统设备的尾部所在方向递送，辅助吊车保持不动。随着主力吊车不断地提升、变幅，将主系统设备从横卧状态转动至直立状态。
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。
拆除辅助吊车与主系统设备的尾部的连接包括：断开第二吊具与第二吊接件的连接，通过主力吊车将主系统设备直立放置在定位支架上，使主系统设备尾部上的第二吊接件与定位支架配合，最后将主系统设备尾部上的第二吊接件从尾部上拆下。第二吊接件脱离主系统设备的尾部后，主力吊车再通过提升、回转、变幅及下降等动作将主系统设备起吊至安装位置。
对于将主系统设备起吊至安装位置，可操作如下：将主系统设备吊起到安全壳的顶部上方，从安全壳的开放顶部进入并下放至安全壳内，完成所需主系统设备的吊装后，再将安全壳的顶盖封闭在安全壳的顶部。
主系统设备在安装位置上就位，由于主系统设备以直立状态就位，其头部形成主系统设备的顶部，尾部形成主系统设备的底部。
在另一些实施例中，本发明的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。
步骤S1具体可包括：
S1.1、将第一吊接件安装在主系统设备的头部上，将第二吊接件安装在 主系统设备的尾部上；
S1.2、将主力吊车通过第一吊具连接第一吊接件，将辅助吊车通过第二吊具连接第二吊接件。
其中，第一吊具和第一吊接件的连接为活动连接，以使得在主力吊车通过第一吊具吊起第一吊接件时，第一吊接件可相对第一吊具转动。同理，第二吊具和第二吊接件的连接为活动，第二吊接件可相对的第二吊具转动。
S2、主力吊车和辅助吊车同时提升，将主系统设备起吊至预定高度。
预定高度应满足主系统设备的尾部相对头部翻转至直立时所需高度要求。例如，该预定高度可等同于主设备系统直立时的整体高度，也可以在主设备系统直立时的整体高度的基础上增减。
S3、主力吊车保持不动，辅助吊车落钩以将主系统设备的尾部下放并同时向头部所在方向递送，直至将主系统设备从横卧状态转为直立状态(铅垂状态)。
其中，辅助吊车在下放主系统设备的尾部时，缓慢落钩和变幅，向主系统设备头部所在方向递送。
S4、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。
拆除辅助吊车与主系统设备的尾部的连接包括：断开第二吊具与第二吊接件的连接，通过主力吊车将主系统设备直立放置在定位支架上，使主系统设备尾部上的第二吊接件与定位支架配合，最后将主系统设备尾部上的第二吊接件从尾部上拆下。第二吊接件脱离主系统设备的尾部后，主力吊车再通过提升、回转、变幅及下降等动作将主系统设备起吊至安装位置。
对于将主系统设备起吊至安装位置，可操作如下：将主系统设备吊起到 安全壳的顶部上方，从安全壳的开放顶部进入并下放至安全壳内，完成所需主系统设备的吊装后，再将安全壳的顶盖封闭在安全壳的顶部。
主系统设备在安装位置上就位，由于主系统设备以直立状态就位，其头部形成主系统设备的顶部，尾部形成主系统设备的底部。
参考图1、2，当主系统设备为SG(蒸汽发生器)10时，在一种选择性实施方式中，第一吊接件包括两个管轴式吊耳20，第二吊接件为翻转抱环30，翻转抱环30通常由两个半圆套箍连接形成。
步骤S1.1具体操作如下：
将两个管轴式吊耳20安装在蒸汽发生器10头部的两个对称的人孔上：将管轴式吊耳20前端插入人孔中，使管轴式吊耳20与人孔的端面接触，用螺栓将管轴式吊耳固定在人孔的法兰凸台的螺纹孔内，按规定预紧力矩值紧固。
将翻转抱环30的两个半圆套箍相对配合到蒸汽发生器10尾部的外周上，将两个半圆套箍的对接端用螺栓连接紧固；螺栓紧固时应按一定顺序交替进行。由于在吊起蒸汽发生器10时，主要靠翻转抱环与蒸汽发生器10间的摩擦力承受载荷，因此为增大摩擦力，可在翻转抱环30与蒸汽发生器10接触面之间设置胶皮。
对应地，第一吊具40包括用于与主力吊车的吊钩连接的平衡梁41、连接在平衡梁41相对两端并垂直向下的两个第一吊件42；第一吊件42可以是吊绳或吊杆。吊绳可优选无接头绳圈。平衡梁41的顶部设置转换接头，该转换接头通过索具与主力吊车的吊钩连接。
如图1所示，在第二吊具的一实施例中，其包括吊绳50，与辅助吊车的吊钩连接。
在步骤S1.2中，将两个第一吊件42远离平衡梁41的端部连接在管轴式吊耳20上，每一个第一吊接件42的端部套设到一个管轴式吊耳20上，并且可相对管轴式吊耳20转动。
对于吊绳50，翻转抱环30上设置一个吊点。在蒸汽发生器10处于横卧状态下，该吊点位于蒸汽发生器10尾部朝上的侧面上；该吊点通过卸扣连接吊绳50。
如图3所示，在第二吊具的另一实施例中，第二吊具包括横梁51及连接在横梁51相对两端并垂直向下的两个第二吊件52。翻转抱环30上设置两个吊点时；在蒸汽发生器10处于横卧状态下，两个吊点位于蒸汽发生器10尾部左右相背的两侧面上；横梁51通过至少一组吊绳连接辅助吊车，每一第二吊件52远离横梁51的端部分别与蒸汽发生器10尾部每一侧面上的吊点连接，并且第二吊件52可相对吊点转动。每一吊点可由凸出在翻转抱环30上的轴套和定位环配合形成。吊点的中心线与蒸汽发生器10人孔中心线平行，其平行允差0.6mm。
当主系统设备为SG(蒸汽发生器)10时，在另一种选择性实施方式中，第一吊接件包括两个管轴式吊耳，第二吊接件也包括两个管轴式吊耳。第一吊接件和第二吊接件在蒸汽发生器10头部和尾部上安装时，将第一吊接件的两个管轴式吊耳安装在蒸汽发生器10头部的两个对称的人孔上，将第二吊接件的两个管轴式吊耳安装在蒸汽发生器10尾部的两个对称的手孔上，可参考图1中所示管轴式吊耳20在蒸汽发生器10上的安装。
对应地，第一吊具和第二吊具均可由平衡梁、连接在平衡梁相对两端并垂直向下的两个吊件等构成；吊件可以是吊绳或吊杆。在SG头部，第一吊具以其平衡梁连接主力吊车，以吊件远离平衡梁的端部连接第一吊接件的管轴 式吊耳。在SG尾部，第二吊具以其平衡梁连接辅助吊车，以吊件远离平衡梁的端部连接第二吊接件的管轴式吊耳。第一吊具和第二吊具与管轴式吊耳的连接均可参考上述图2所示连接方式。
对于上述的实施方式，吊装SG时，直接利用SG头部和尾部上具有的孔结构进行吊接件(管轴式吊耳)的可拆卸安装，无需再额外设置吊点(如焊接吊耳)，减少零件等投入，还可提高效率。
在吊起蒸汽发生器10时，可根据需要选择上述两种实施方式中任一种：主力吊车提升将蒸汽发生器10的头部吊起，辅助吊车将蒸汽发生器10的尾部向头部所在方向递送，直至将蒸汽发生器10从横卧状态转为铅垂状态；或者，主力吊车提升将蒸汽发生器10的头部吊起并向尾部所在方向递送，辅助吊车保持不动，直至将蒸汽发生器10从横卧状态转为铅垂状态；或者，主力吊车和辅助吊车同时提升，将蒸汽发生器10起吊至预定高度，主力吊车保持不动，辅助吊车落钩以将蒸汽发生器10的尾部下放并同时向头部所在方向递送，直至将蒸汽发生器10从横卧状态转为铅垂状态。最后再将蒸汽发生器10吊入安全壳内进行安装就位。
如图4所示，当主系统设备为压力容器(RPV)60时，在一种选择性实施方式中，第一吊接件为吊装盖板70，可拆卸安装在压力容器60的头部上。第二吊接件为翻转抱环80，翻转抱环80通常由两个半圆套箍连接形成。
步骤S1.1具体操作如下：
将吊装盖板70安装在压力容器60的头部上；将翻转抱环80的两个半圆套箍相对配合到压力容器60尾部的外周上，将两个半圆套箍的对接端用螺栓连接紧固；螺栓紧固时应按一定顺序交替进行。由于在吊起压力容器60时，主要靠翻转抱环80与压力容器60间的摩擦力承受载荷，因此为增大摩擦力， 可在翻转抱环80与压力容器60接触面之间设置胶皮。
第一吊具91可包括吊绳，或者包括平衡梁、连接在平衡梁相对两端并垂直向下的两个吊件；第二吊具92可包括吊绳，或者包括平衡梁、连接在平衡梁相对两端并垂直向下的两个吊件。
在步骤S1.2中，当第一吊具91包括吊绳时，吊装盖板70上设置一个吊点，位于压力容器60的中轴线上；以吊绳连接在主力吊车和吊点之间。当第一吊具91由平衡梁及吊件等组成时，吊装盖板70上设置两个对称的吊点，平衡梁通过吊绳连接主力吊车，两个吊件远离平衡梁的末端分别与两个吊点连接。
当第二吊具92包括吊绳时，翻转抱环80上设置一个吊点。在压力容器60处于横卧状态下，该吊点位于压力容器60尾部朝上的侧面上；该吊点通过卸扣连接吊绳。当第二吊具92由平衡梁及吊件等组成时，翻转抱环80上设置两个吊点；在压力容器60处于横卧状态下，两个吊点位于压力容器60尾部左右相背的两侧面上；平衡梁通过吊绳连接辅助吊车，两个吊件远离平衡梁的末端分别与两个吊点连接。
在吊起压力容器60时，可根据需要选择上述两种实施方式中任一种：主力吊车提升将压力容器60的头部吊起，辅助吊车将压力容器60的尾部向头部所在方向递送，直至将压力容器60从横卧状态转为铅垂状态；或者，主力吊车提升将压力容器60的头部吊起并向尾部所在方向递送，辅助吊车保持不动，直至将压力容器60从横卧状态转为铅垂状态；或者，主力吊车和辅助吊车同时提升，将压力容器60起吊至预定高度，主力吊车保持不动，辅助吊车落钩以将压力容器60的尾部下放并同时向头部所在方向递送，直至将压力容器60从横卧状态转为铅垂状态。最后再将压力容器60吊入安全壳内进行安 装就位。
当主系统设备为稳压器时，其吊装方法可参考上述蒸汽发生器和压力容器的吊装。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
