本实施例中，夹持单元3能够相对于底座单元1在翻转位置和缩回位置之间移动，在初始状态下，塔筒翻转工装的夹持单元3处于缩回位置，图未示，此夹持单元3位于安装船7上方，即夹持单元3的大致全部结构位于安装船7的上方，塔筒翻转工装处于此状态时，尤其适用于塔筒段的海上运输过程。
在需要对塔筒段12进行翻转时，夹持单元3可以移动至翻转位置，夹持单元3至少部分位于安装船7周向外侧，夹持单元3能够在翻转单元2的带动下绕第一旋转轴线转动，如图1至图7所示状态。
本公开通过将夹持单元3设置为能够在翻转位置和缩回位置之间移动，在夹持单元3处于翻转位置时，能够满足塔筒段的翻转需求；在夹持单元3处于缩回位置时，夹持单元3大致处于安装船7上方，即避免夹持单元3延伸至安装船7周向边缘之外，提高了安装船7移动过程中的安全性。
本公开中的底座单元1可以包括滑块5，夹持单元3可以连接在滑块5上，以能够在缩回位置和翻转位置之间移动。
继续参照图1至图2以及图4至图6，底座单元1包括固定座4、滑块5以及滑块驱动件6，固定座4用于固定在安装船7上，例如但不限于，固定座4可以固定于安装船7的甲板上。滑块5可滑动地连接在固定座4上，滑块驱动件6连接在固定座4和滑块5之间以能够驱动滑块5滑动。
为了提高固定座4与甲板的连接稳定性，固定座4的周向外侧设置有多个加强筋8，以增加固定座4与甲板的连接面积。
作为示例，本实施例中，滑块驱动件6为伸缩缸，例如但不限于，液压缸或气缸，还可以为丝杆组件。
具体地，固定座4沿着垂直于第一旋转轴线的方向延伸，在固定座4的宽度方向的中部设置有滑槽9，该滑槽9沿着固定座4的延伸方向延伸，滑块5可滑动地设置于该滑槽9内。
本实施例中，为了防止滑块5与滑槽9意外脱离，在滑槽9的延伸方向的两端可以设置有止挡结构，但不以此为限。
进一步地，滑块5的横截面大致呈“工”字型，滑槽9与滑块5匹配，如此便于对滑块5进行纵向限位。
继续参照附图，为了便于支撑夹持单元3，滑块5上设置有斜撑臂37，夹持单元3可转动地设置于斜撑臂37上。作为示例，斜撑臂37从安装船7的中部向边缘倾斜向上延伸。如此设置，通过在滑块5上设置斜撑臂37，方便夹持单元3在翻转位置时能够稳定可靠地支撑在安装船7上。
进一步地，斜撑臂37的延伸方向与滑块5的滑动方向之间的夹角α满足65°≤α≤85°。若夹角α过小，斜撑臂37大致呈悬臂结构，由于塔筒段直径较大，重量较大，悬臂结构易于弯曲或损坏，难以对塔筒段进行稳定可靠支撑；若夹角α过大，需要较长的斜撑臂37才能延伸至安装船7之外，而斜撑臂37长度过大在运输过程中易于晃动、抖动或者弯曲，从而难以为塔筒段进行稳定可靠支撑。作为示例，本实施例中夹角α大致为75°，但不以此为限。
继续参照附图，翻转单元2包括杆臂27、连杆18以及翻转驱动组件，翻转驱动组件设置于底座单元1上，翻转驱动组件能够驱动杆臂27绕第二旋转轴线转动，连杆18的两端分别与杆臂27和夹持单元3转动连接，以通过杆臂27的转动带动夹持单元3相对于底座单元1转动。作为示例，第二旋转轴线大致与第一旋转轴线平行，但不以此为限。
除此，连杆18还可以为伸缩式结构，以能够进一步提高塔筒翻转工装的通用性。
进一步地，连杆18连接于杆臂27的第一端，杆臂27的与第一端相对的第二端固定有轴杆17。参照图6和图7，翻转驱动组件包括翻转电机13、主动轮15以及从动轮16，主动轮15固定于翻转电机13的输出轴上，从动轮 16固定于轴杆17上，主动轮15和从动轮16之间齿啮合或者设置有传送带。本实施例中，轴杆17和翻转电机13之间的力传动是通过主动轮15和从动轮16之间的齿啮合来实现的，提高了力传递的精度。另外，通过设置主动轮15和从动轮16，可以改变轴杆17的转速。
除此，翻转驱动组件包括翻转电机13，翻转电机13的输出轴固定于轴杆17上，第一旋转轴线与输出轴的中心线重合，即本实施例中，翻转电机13的输出轴与轴杆17直接固定，以将翻转电机13的力直接传递给轴杆17，但不以此为限。
进一步地，翻转单元2还可以为液压缸、气缸或者丝杆组件等部件，以用于驱动夹持单元3绕第一旋转轴线转动，都在本公开的保护范围内。
继续参照图1和图2，夹持单元3包括底板29和相对设置的一对夹持块33，底板29用于对夹持单元3和待夹持的塔筒段进行支撑，底板29能够绕第一旋转轴线旋转，以实现夹持单元3的翻转。作为示例，底板29的沿第一旋转轴线方向的两侧设置有一对旋转轴30，底板29通过旋转轴30连接于斜撑臂37上，旋转轴30的轴线与第一旋转轴线重合。进一步地，在旋转轴30和斜撑臂37之间可以设置有轴承38，如图2所示，但不以此为限。
夹持块33绕夹块旋转轴线可转动地连接于底板29上，夹块旋转轴线活动地设置于底板29上。本实施例中，通过夹持块33绕夹块旋转轴线转动，可以实现夹持块33对塔筒段的夹持和放开，即两个夹持块33相对设置，以形成为类似剪刀结构，能够对塔筒段进行夹持。作为示例，夹持块33的内壁与塔筒段的外周壁匹配，以能够稳定可靠地夹持塔筒段，塔筒段的外周壁能够与夹持块33的内壁贴合，例如，夹持块33的内壁为弧形，可以与塔筒段的外周壁匹配，但不以此为限。
通过将夹块旋转轴线活动地设置于底板29上，能够调整夹持块33对应的塔筒段的直径，从而提高了塔筒翻转工装的通用性。
具体地，参照图2和图3，夹持单元3还包括夹块移动驱动组件，夹块移动驱动组件包括齿条36、齿轮35以及齿轮驱动件34，齿轮35可转动地连接在夹持块33上，例如但不限于，齿轮35设置在夹持块33的轴向顶端或者底端，且齿轮35的旋转中心线与夹块旋转轴线重合，齿轮35与齿条36之间齿啮合，齿轮驱动件34能够带动齿轮35转动。作为示例，齿轮驱动件34可以为电机，但不以此为限。
电机的输出轴可以固定于齿轮35上，以通过齿轮35的转动驱动齿轮35沿齿条36滚动，从而调整两个夹持块33之间的距离，以能够调整夹持单元3的夹持直径，从而提高了塔筒翻转工装的通用性。作为示例，夹持块33的轴向两端设置有横轴42，横轴42通过轴承连接于齿轮35上。
进一步地，每个夹持块33的轴向两端分别对应设置有上述夹块移动驱动组件，在上述实施例中，夹持块33将沿齿条36平动，避免齿轮35与齿条36卡死，从而提高了塔筒翻转工装的运行可靠性。
作为示例，夹持块33的齿条36相对于与其相对的夹持块33向外倾斜向上延伸，例如但不限于，齿条36与底板29之间的夹角β满足30°≤β≤60°。可选地，夹角β可以为45°，但不以此为限。
作为示例，底板29顶面突出设置有支撑板43，齿条36设置于该支撑板43上，但不以此为限。每个夹持块33的轴向两端分别设置有一个支撑板43，但不以此为限。
继续参照附图，夹持单元3还包括支撑块32，支撑块32可转动地设置于一对夹持块33之间且位于夹持块33的下方，用于在下方支撑塔筒段，从而进一步提高了塔筒翻转工装的可靠性。作为示例，支撑块32的转动轴线平行于夹块旋转轴线，通过支撑块32设置为可转动结构，便于与塔筒段的外周壁贴合，从而进一步提高了塔筒翻转工装的可靠性。参照图4和图5，支撑块32的下方设置有中间轴39，中间轴39的轴线与转动轴线重合，即支撑块32绕中间轴39转动。
作为示例，夹块旋转轴线垂直于第一旋转轴线，但不以此为限。以图5为例，本实施例中，夹块旋转轴线大致平行于底板29且左右方向延伸，第一旋转轴线大致垂直纸面延伸，但不以此为限。
夹持单元3还包括摆动伸缩件31，摆动伸缩件31的顶端和底端分别设置于夹持块33和底板29上，摆动伸缩件31的顶端布置于夹持块33的外侧，且摆动伸缩件31大致垂直于夹块旋转轴线设置。继续参照图5，本实施例中，摆动伸缩件31垂直于底板29设置，但不以此为限。
为了进一步提高塔筒翻转工装的可靠性，夹持单元3还包括压力传感器44，压力传感器44设置于夹持块33的内侧，以能够与塔筒段12表面接触。待压力传感器44的监测数值达到预定值时，夹持单元3动作，避免由于夹持力不足而造成安全隐患。
本公开提供的塔筒翻转工装可安装在海上安装船7的甲板面上，以能够带动整段塔筒段12从水平状态翻转至竖直状态。塔筒翻转工装底座单元1、翻转单元2和夹持单元3。
底座单元1固定在安装船7的甲板面上，作为塔筒翻转工装的主要基座，用来支撑翻转单元2、夹持单元3和整段塔筒段12。底座单元1包括固定座4和滑块5，滑块5可以在固定座4的滑槽9内滑动，通过滑块驱动件6的伸缩动作，可以实现滑块5在滑槽9内的移动。当使用塔筒翻转工装翻转塔筒段12时，滑块驱动件6动作驱动滑块5向安装船7外移动，使塔筒翻转工装上的夹持单元3移动至甲板面外，至翻转位置为止，这样塔筒段12在翻转过程中不会与安装船7的船舷部件干涉。
当不需要使用塔筒翻转工装时，滑块驱动件6动作驱动滑块5向甲板面内移动，至缩回位置，使塔筒翻转工装上的夹持单元3移动至甲板面内，避免安装船7在移动过程中塔筒翻转工装不会与船外部件碰撞。
翻转单元2用来翻转夹持单元3和塔筒段12，主要由翻转电机13、相齿啮合的主动轮15和从动轮16，通过翻转电机13的输出轴14固定在主动轮15上，以能够将扭矩传递给主动轮15，主动轮15与从动轮16相互啮合，以带动从动轮16旋转，并带动轴杆17旋转，轴杆17推动连杆18及其与之连接的夹持单元3绕第一旋转轴线旋转，从而实现塔筒段12的翻转。
为了提高塔筒翻转工装的安全性，塔筒翻转工装还包括机箱19，如图2、图4以及图6所示，翻转电机13可设置于机箱19的外侧，即沿轴杆17的轴向外侧，翻转电机13的输出轴14可以通过轴承连接在机箱19的机箱外侧板20上，轴杆17可通过轴承连接在机箱19的机箱内侧板25上，主动轮15和从动轮16布置在机箱19内，避免齿轮外露而带来安全隐患，从而提高了塔筒翻转工装的安全性。
夹持单元3用来夹持整段塔筒段12，塔筒段12放置在支撑块32的上方，夹持块33对其进行夹持，以避免安装船7移动过程中，或夹持单元3翻转过程中，塔筒段12相对夹持单元3出现意外滑动而导致安全隐患。
支撑块32可以绕转动轴线转动，以能够适应塔筒段12的外周壁的形状，从而实现塔筒段12的稳定夹持。
通过将夹持块33的夹块旋转轴线活动地设置于底板29上，提高了夹持块33的通用性，以使夹持单元3能够适应不同直径的塔筒段12。当夹持不 同直径的塔筒段12时，可以根据塔筒段12直径大小，通过齿轮驱动件34动作，齿轮35带着横轴42以及夹持块33移动以调整夹持块33的位置，当位置调整结束后横轴42固定不动，通过伸缩件31动作，以驱动夹持块33绕着横轴42旋转，从而实现夹持和释放塔筒段12的动作。
在一对夹持块33内侧都设置有压力传感器44，用来测量夹持块33对塔筒段12的夹持力，在夹持力满足要求后，夹持单元3可以翻转，从而避免塔筒段12意外滑落导致安全隐患。
安装船7上的主吊将塔筒段12水平吊装至支撑块32上，拆除主吊与塔筒段12的连接，伸缩件31动作，夹持块33绕着横轴42旋转紧密贴合塔筒段12的表面上，夹持块33内侧的压力传感器44，监测到夹持块33与塔筒段12间的夹持力满足预定值时，翻转单元2动作。
主吊带着塔筒吊具与塔筒段12的顶法兰连接，但此时主吊不带提升力，然后翻转电机13动作，通过输出轴14将扭矩传递给主动轮15，主动轮15与从动轮16相互啮合，从动轮16旋转，并带动轴杆17旋转，轴杆17推动连杆18及其与之连接的夹持单元3和塔筒段12将会绕着斜撑臂37内的轴承中心翻转，轴承的中心与第一旋转轴线重合。翻转过程中，主吊的吊臂也要跟着塔筒段12一起动作，保持主吊的吊点在塔筒段12顶法兰的正上方。
将塔筒段12翻转至竖直状态后，翻转电机13停止动作，主吊提力，待提升力达到塔筒段12的自身重量时，伸缩件31动作，将夹持块33完全打开，最后主吊吊着塔筒段12撤离塔筒翻转工装，转至基础桩上方进行塔筒段12的安装。
本公开提供的塔筒翻转工装能够实现整段塔筒段12在海上安装船7上从水平状态到竖直状态的翻身吊装，保证了整段塔筒段12施工方案的可行性，提高了海上机组的安装效率，同时也减少了塔筒的生产制造成本。
塔筒翻转工装的使用保证整段塔筒段12的施工无需额外配置高性能安装船(辅吊吊重能力特别大的)，普通的安装船7即可，对于市场上大众化的船都能施工，从而降低施工成本。
塔筒翻转工装的夹持单元3具有通用性，可根据不同塔筒段12的直径调节夹持块33的位置，可以满足不同直径的塔筒段12翻身吊装，从而进一步降低了塔筒段12的运输成本。
