Description

单桩基础导向装置 技术领域
本公开涉及海上风力发电技术领域，更具体地讲，涉及一种用于海上风力发电机组的单桩基础导向装置。
背景技术
在用于海上风力发电机组的各种风机基础中，单桩基础除了具有制造简单和对设备成本要求较低的优点之外，还具有优越的施工效率的优势。因此，90％以上的海上风力发电机组采用单桩基础。
然而，对单桩基础的垂直度要求极高，圆周方向平面的最大高度差需要小于设定值。，在单桩基础施进行锤击使其贯入海床的工过程中，如果出现锤击偏差，则此单桩基础很可能出现报废的风险，从后期修复方案到执行或者重新衔接过渡段法兰纠正垂直度，再加上海上施工船舶和吊机的成本，都将是巨额的损失。因此，单桩基础施工，垂直度控制是关键。
现有技术中的部分单桩基础导向装置采用多个油缸结构，在多个不同位置对单桩基础进行夹紧，难以进行同步操作，垂直度同步控制精度低。另一方面，由于多个油缸需要多人控制，在单桩基础施工时，每次都需要测量每个油缸的伸出长度，在锤击单桩过程中，需要随时关注每个油缸的受力情况，单桩每下降一定高度，需要停锤并测量垂直度，如果出现偏差，需要再次单独推动每个油缸调节单桩垂直度，如此往复，操作过程复杂，效率低。
此外，现有技术中的单桩基础导向装置中，油缸安装在平台顶部，操作人员需要爬到平台顶部操作油缸以及测量油缸伸出长度，存在人员坠落风险。
发明内容
本公开的目的在于提供一种操作简单、安全性能高且能够精准控制单桩基础的垂直度的单桩基础导向装置。

根据本公开的一方面，所述至少一个导向单元包括第一导向单元，所述第一导向单元包括第一驱动单元、第一传动单元和第一夹持单元，所述第一传动单元包括推块，所述第一驱动单元推动所述推块移动从而驱动所述第一夹持单元闭合以将所述单桩基础抱紧。根据本公开的一方面，所述至少一个导向单元包括第二导向单元，所述第二导向单元包括第二驱动单元、第二传动单元和第二夹持单元，所述第二传动单元包括环形框架，所述第二夹持单元包括多个夹持臂，所述多个夹持臂插入到所述环形框架中，所述第二驱动单元推动所述环形框架旋转，从而通过所述环形框架带动所述多个夹持臂同步枢转。
本公开摈弃传统的三缸或四缸油缸，单独控制夹持臂的推动形式，采用单驱动结构，各个夹持臂同步同心枢转，能实现单桩施工过程中垂直度的精准控制，操作简单，受力平稳，安全可靠。

具体实施方式
为了解决现有技术中的多个液压缸分别驱动多个夹持臂使得多个夹持臂无法同步同轴运动导致垂直度同步控制精度低的问题，本公开提供了一种单桩基础导向装置，该单桩基础导向装置包括至少一个导向单元，每个导向单元可包括单个驱动单元、传动单元和夹持单元，通过单个驱动单元将动力传递给传动单元，通过传动单元来驱动夹持单元的至少两个夹持臂同步操作，从而夹持单元的多个夹持臂能够同时打开或闭合，保证单桩基础的垂直度同步控制精度。
以下，参照附图来详细说明本公开的实施例。
图1-图5示出了根据本公开第一实施例的单桩基础导向装置的结构示意图。
根据本公开第一实施例的单桩基础导向装置包括导向支撑架100以及设置在导向支撑架100上的第一导向单元1000。
如图1和图2所示，导向支撑架100包括多个定位桩110以及固定在定位桩110上的第一支撑平台120。定位桩110为柱状结构，第一支撑平台120与定位桩110焊接或者栓接，定位桩110可与船体连接或者穿入海底，形成稳固支撑结构。在本公开的实施例中，定位桩110设置为四根，围拢成矩形形状。第一支撑平台120形成为一侧开口的矩形框架，四角分别与定位桩110固定连接。但是，本公开的导向支撑架100的定位桩110的数量不限于此，定位桩110可以为至少三根，第一支撑平台120的外形不限于矩形，也可以为圆形或半圆形，只要内侧形成适于安装第一导向单元1000的空间即可。
第一导向单元1000安装在第一支撑平台120上。第一支撑平台120形成为一侧开口的凹形结构，第一导向单元1000安装在第一支撑平台120的凹口内，用于在吊装单桩基础10时对单桩基础10进行导正，以及在对单桩基础进行锤击的过程中，对单桩基础10施加夹紧力以保证单桩基础10的垂直度。
如图3-图5所示，第一导向单元1000可包括第一驱动单元300、第一传动单元400和第一夹持单元500。第一夹持单元500具有容纳单桩基础10的夹持空间。第一驱动单元300将驱动力传递给第一传动单元400，通过第一传动单元400驱动第一夹持单元500闭合或打开，以将单桩基础10抱紧或松开。下面，更详细地描述第一导向单元1000的具体结构。
第一夹持单元500可以包括第一夹持臂510和第二夹持臂520。第一夹持臂510和第二夹持臂520可以为对称结构，第一夹持臂510和第二夹持臂520之间形成容纳单桩基础10的容纳空间。作为示例，第一支撑平台120的内侧壁可以包括第一内侧壁121以及位于第一内侧壁121两侧的第二内侧壁122和第三内侧壁123，第一夹持臂510和第二夹持臂520可分别安装在第一支撑平台120的第二内侧壁122和第三内侧壁123上。
在第一夹持臂510的第一端上可设置有第一挤压滚轮511，在第二端上设置有第一支撑滚轮512。第一夹持臂510可与第一支撑平台120铰接，具体地，第一夹持臂510可以为刚性曲连杆，在刚性曲连杆的中部位置通过第一铰接轴515铰接到第一支撑平台120的第二侧壁122上。第一夹持臂510能够围绕第一铰接轴515在一定角度范围内枢转。
在第二夹持臂520的第一端上可设置有第二挤压滚轮521，在第二端上设置有第二支撑滚轮522。第二夹持臂520可与第一支撑平台120铰接，具体地，第二夹持臂520可以为刚性曲连杆，在刚性曲连杆的中部位置通过第二铰接轴525铰接到第一支撑平台120的第三侧壁123上。第二夹持臂520能够围绕第二铰接轴525在一定角度范围内枢转。
第一传动单元400可包括推块410，第一驱动单元300推动推块410向着第一夹持单元500的夹持空间移动，从而驱动第一夹持单元500闭合以将单桩基础10抱紧。可在第一支撑平台120上设置限位机构，限制推块410的运动轨迹，例如，在第一支撑平台120上设置凹槽，在推块410的下表面上设有与凹槽匹配的凸起，使凸起卡合在凹槽中，并能够在凹槽中运动。通过限位机构，引导推块410的运动，使推块410只能沿着特定的轨迹移动，以对第一夹持单元500施加稳定的驱动力。
推块410可包括相对设置的第一锥面411和第二锥面412。具体地，第一锥面411和第二锥面412之间的距离向着夹持空间的方向缩小，从而推块410形成的锥体的顶部面向夹持空间。第一夹持臂510通过第一支撑滚轮512 抵接在第一锥面411上，第二夹持臂520通过第二支撑滚轮522抵接在第二锥面412上。第一支撑滚轮512能够沿着第一锥面411滚动，第二支撑滚轮522能够沿着第二锥面412滚动。
当第一驱动单元300将推块410向着夹持空间推动时，推块410两侧的第一锥面411和第二锥面412分别将力传递给第一支撑滚轮512和第二支撑滚轮522，从而推动第一夹持臂510和第二夹持臂520分别围绕铰接轴515和525枢转，与此同时，第一挤压滚轮511和第二挤压滚轮521将向着夹持空间移动以调整夹持空间大小或者调整对单桩基础10的挤压力。
除了第一夹持臂510和第二夹持臂520之外，第一夹持单元500还可包括第三夹持臂，第三夹持臂可以固定安装在推块410上，位于推块410的面向夹持空间的一侧上。第三夹持臂上可安装有第三挤压滚轮531。在附图所示的示例中，第三夹持臂较短，形成为用于将第三挤压滚轮531安装在推块410上的滚轮支架，该滚轮支架可与推块410焊接固定。
在推块410向着夹持空间移动时，第一挤压滚轮511、第二挤压滚轮521以及第三挤压滚轮531能够同步同轴运动，同时抵接单桩基础10的外表面，并同时对单桩基础10施加抱紧力，使得单桩基础10在圆周方向上受到对称的挤压力，以保证单桩基础10的垂直度。
虽然在本公开的实施例中，还包括第三夹持臂，但是，第三夹持臂不是必须的。例如，第一夹持臂510的安装第一挤压滚轮511的一端可以形成有弧形夹板，以在单桩基础的外侧包围单桩基础的外圆周的一部分。弧形夹板的内侧表面上也可以设置有多个挤压滚轮，以通过多个挤压滚轮与单桩基础的外表面滚动接触。相应的，第二夹持臂520的安装第二挤压滚轮521的一端也形成有弧形夹板，弧形夹板的内侧也可以安装多个挤压滚轮。在推块410推动第一夹持臂510和第二夹持臂520枢转闭合时，两个弧形夹板从单桩基础的两侧对称挤压单桩基础，从而将单桩基础抱紧并保证单桩基础的垂直度。
根据本公开的实施例，通过单个驱动单元300驱动推块410，并通过推块410驱动多个夹持臂同步操作，使得多个挤压滚轮同时抵接单桩基础10的外表面。在本公开中，第一驱动单元300的结构和安装位置不受限制，只要第一驱动单元300能够推动推块410向着夹持空间移动，推动第一夹持臂510和第二夹持臂520同步枢转即可。
根据本公开的第一实施例，提供了一种实现第一驱动单元300的示例。
如图3-图5所示，推块410还包括第一倾斜表面413，第一锥面411和第二锥面412位于第一倾斜表面413的两侧。换句话说，第一倾斜表面413形成在推块410的背对夹持空间的一侧。第一驱动单元300包括液压缸310和连接到液压缸一端的楔块320，楔块320具有第二倾斜表面321，第二倾斜表面321与第一倾斜表面413相面对并相互接触，当液压缸310伸出而推动楔块320沿所述第一方向移动时，楔块320推动推块410第二方向移动移动。第一方向和第二方向可以均在水平面内，均与单桩基础的轴线方向垂直。
第一驱动单元300可安装在第一支撑平台120的第一内侧壁121上，楔块320能够在第一内侧壁121上沿着第一方向滑动，从而将液压缸310的沿第一方向的驱动力转换为推块410沿着第二方向移动的动力。
为了稳定地控制楔块320和推块410的运动路线，可以在楔块320和推块410上分别设置凸起，在第一支撑平台120上分别设置相应的凹槽，通过将凸起设置在凹槽中来引导楔块320和推块410的运动路线。
三个挤压滚轮511、521和531可以沿着单桩基础10的外圆周均匀对称布置，在这种情况下，可以通过设计推块410的第一锥面411、第二锥面412的锥度使得三个挤压滚轮511、521和531对单桩基础10施加同样的挤压力。此外，还可以调整推块410的面向夹持空间的表面的倾斜角度。此外，三个挤压滚轮不一定均匀设置，只要能够使得单桩基础10在各个方向上的受力对称即可。
虽然附图中没有示出，但是可以理解的是，第一支撑平台120还可包括支撑第一驱动单元300和第一传动单元400的水平支撑板。具体地，水平支撑板可设置在推块410和楔块320下方，以支撑推块410和楔块320的底表面，使得推块410和楔块320在水平方向上稳定地滑动。
第一支撑滚轮512可滚动地支撑在推块410的第一锥面411上，第二支撑滚轮522可滚动地支撑在推块410的第二锥面412上。随着推块410向着夹持空间移动，推块410通过第一锥面411和第二锥面412分别将第一支撑滚轮512和第二支撑滚轮522向两侧推动，带动第一夹持臂510和第二夹持臂520围绕铰接轴515和525枢转，从而第一挤压滚轮511和第二挤压滚轮521相对于夹持空间向内移动，抵接单桩基础10的外表面，对单桩基础10施加抱紧力。与此同时，随着推块410向着夹持空间移动，安装在推块410上的第三挤压滚轮531也到达单桩基础10的外表面，与第一挤压滚轮511和 第二挤压滚轮521同时对单桩基础10施加抱紧力。通过调节液压缸310的伸出长度，可以调节夹持空间的大小以及对单桩基础10施加的抱紧力的大小。图4示出了第一夹持单元500闭合以对单桩基础10施加抱紧力的示意图。
作为一个可选示例，楔块320可以为三角形楔块，优选为直角三角形楔块。具体地，楔块320的横截面形状可以是直角三角形，三角形的长直角边(也可称为底边)与第一支撑平台120的第一内侧壁121相面对并接触，以在第一内侧壁121上滑动。三角形的短直角边垂直于第一内侧壁121，第一驱动单元300可以连接到楔块320的短直角边上。楔块320的与三角形斜边对应的斜面(即，第二倾斜表面321)和推块410的第一倾斜表面413相面对并接触。推块410位于楔块320和夹持空间之间。
作为示例，第一倾斜表面413和第二倾斜表面321的倾斜角度可以为10°-30°，优选为20°。倾斜角度小，第一倾斜表面413和第二倾斜表面321之间的接触面积大，油缸行程大，调整速度慢。倾斜角度大，第一倾斜表面413和第二倾斜表面321之间的接触面积小，油缸行程小，调整速度快。因此，可以根据调整需求来设置第一倾斜表面413和第二倾斜表面321的倾斜角度。
当液压缸伸出时，楔块320将推块410向外顶出，推动推块410远离第一内侧壁121，向着第一导向单元500的夹持空间移动。当液压缸310缩回时，楔块320退回，从而撤销对推块410的推力。
随着楔块320退回，推块410也需要同时退回。为了使得推块410能够跟随楔块320向后回退，楔块320和推块410相抵接的两个倾斜表面321和413上可以分别设置有滑槽和滑轨，滑轨可以卡合在滑槽中，从而楔块320和推块410能够相互活动连接，使得推块410能够随着楔块320一起运动，在楔块320向后退时，推块410也能够向着第一内侧壁121回退，远离夹持空间。
然而，根据本公开的实施例，使推块410回退的方案不限于此，也可以在第一内侧壁121上设置回复弹簧，对推块410施加拉力，从而在楔块320回退时，推块410也可以在回复弹簧的拉力下向着第一内侧壁121移动。
当液压缸310缩回时，推块410逐渐朝向第一内侧壁121靠近，从而第三挤压滚轮531离开单桩基础10的外表面，撤去对单桩基础10的挤压力。与此同时，随着推块410后退，推块410撤去对第一支撑滚轮512和第二支撑滚轮522的推力，第一夹持臂510和第二夹持臂520枢转打开，第一挤压 滚轮512和第二挤压滚轮522也同时撤销对单桩10的夹持力。图5示出了第一夹持单元500处于打开状态的示意图。
为了在第一驱动单元300缩回时，第一夹持臂510和第二夹持臂520能够自动向外枢转而打开，在第一铰接轴515和第二铰接轴525上可以设置有复位弹簧，从而在推块410回退而撤销对第一支撑滚轮512和第二支撑滚轮522的推力时，第一夹持臂510和第二夹持臂520的外端能够在复位弹簧的弹力作用下向外打开。此外，回复弹簧也可以设置在第二内侧壁122和第三内侧壁123上。当设置了用于使第一夹持臂510和第二夹持臂520枢转打开的回复弹簧时，可以不用再设置时推块410向后退回的部件，推块410能够在第一支撑滚轮512和第二支撑滚轮522的推动下向后退回。
作为可选方案，还可以在第一锥面411和第二锥面412上设置滚轮槽，将第一支撑滚轮512和第二支撑滚轮522嵌在滚轮槽中，第一支撑滚轮512和第二支撑滚轮522能够卡合在所述滚轮槽中并且能够在所述滚轮槽中滚动。通过卡合在滚轮槽中，第一支撑滚轮512和第二支撑滚轮522不能从推块410的第一锥面411和第二锥面412上脱开，因此，在推块410远离夹持空间时，第一支撑滚轮512和第二支撑滚轮522沿着第一锥面411和第二锥面412向着推块410的顶端滚动，从而第一夹持臂510和第二夹持臂520分别围绕铰接轴515和525枢转而打开夹持空间。
在单桩基础10的沉降过程中，有向下的作用力。根据本公开的实施例，多个夹持臂均通过滚轮与单桩基础10接触，滚轮沿着单桩基础10的外壁向下滚动，减少对单桩基础10的外表面的摩擦，并减少对支撑平台的振动冲击力，降低安全风险，从而增加结构的稳定性。在根据本公开的第一实施例中，滚轮的滚路设计有横向和竖向的区别，与单桩基础10接触的滚轮的滚路沿竖直方向，与推块410接触的滚轮的滚路沿水平方向。
根据本公开第一实施例的单桩基础导向装置，能够通过单个驱动单元300，实现第一夹持单元500的多个挤压滚轮同步同轴运动。在采用液压缸驱动时，只需要控制一个油缸即可，大大减少多个油缸的安装和后期维护成本。此外，通过推块410的两个锥面向支撑滚轮传递推力，可实现夹持臂的枢转角度的无级调整。通过调节第一驱动单元300的液压缸的伸出长度，能够调整第一夹持单元500所形成的夹持空间的大小，从而满足对于不同直径大小的单桩基础的导正需求。根据本公开第一实施例的单桩基础导向装置结构简 单，使得制造周期缩短，成本大大降低。
图6至图9示出了根据本公开第二实施例的单桩基础导向装置。与根据本公开第一实施例的单桩基础导向装置相比，根据本公开第二实施例的单桩基础导向装置还可包括第二导向单元2000，第二导向单元2000在高度方向上与第一导向单元1000隔开预定距离，第二导向单元2000可安装在第一导向单元1000的下方(但不限于此)，从而实现对单桩基础的双层导向功能。
具体地，根据本公开第二实施例的单桩基础导向装置可包括导向支撑架100、设置在导向支撑架100上的第一导向单元1000和第二导向单元2000。导向支撑架100包括多个定位桩110以及固定在定位桩110上的第一支撑平台120和第二支撑平台160，第二导向单元2000安装在第二支撑平台160上。
根据本公开第二实施例的单桩基础导向装置中的第一导向单元与根据本公开第一实施例的单桩基础导向装置中的第一导向单元的结构相同。因此，下面将参照附图6-图9仅描述与第一实施例的单桩基础导向装置不同的部分，即，仅描述第二支撑平台160和第二导向单元2000。
如图7所示，第二支撑平台160包括支撑板161，在支撑板161的中部开设有供单桩基础10穿过的通孔，通孔的直径大于单桩基础10的直径。虽然图中示出的支撑板161为板状，但是，支撑板161也可以由桁架形成，只要能够满足对第二导向单元2000的支撑功能即可。
第二导向单元2000包括第二驱动单元600、第二传动单元700和第二夹持单元800。第二传动单元700可包括环形框架710，第二夹持单元800可包括多个夹持臂810，所述多个夹持臂810可沿着圆周方向对称设置，并在所述多个夹持臂810之间形成用于容纳单桩基础10的夹持空间。所述多个夹持臂810分别插入到环形框架710中，第二驱动单元600能够推动环形框架710旋转，从而通过环形框架710带动所述多个夹持臂810同步枢转。随着夹持臂810的枢转，第二夹持单元800闭合或打开，对单桩基础10施加抱紧力或撤销抱紧力。
第二驱动单元600可包括螺杆驱动结构，具体地，可包括螺杆610、螺杆驱动电机(未示出)、第一螺杆支座620和第二螺杆支座630。
第一螺杆支座620可安装在第二支撑平台160上，并且能够相对于第二支撑平台160旋转。第一螺杆支座620的下端可设置有枢转轴，通过枢转轴连接到第一支撑平台160的支撑板161上。螺杆610的一端插入到第一螺杆 支座620内，螺杆驱动电机可安装在第一螺杆支座620内，以驱动螺杆610旋转。
第二螺杆支座630中可设置有水平螺纹通孔，螺杆610的另一端可穿过第二螺杆支座630的水平螺纹通孔，与第二螺杆支座630螺纹结合。第二螺杆支座630可旋转地安装到环形框架710上。
环形框架710整体上呈环形，中间具有圆形通孔，圆形通孔的直径大于单桩基础10的直径，以供单桩基础10穿过。环形框架710可相对于第二支撑平台160在水平面内旋转，具体地，以单桩基础10的轴线为旋转中心旋转。
第二螺杆支座630可旋转地安装到环形框架710的外边缘上。作为示例，环形框架710的外周边缘设置有一块沿水平方向向环形框架710外延伸的凸板714，第二螺杆支座630可转动地安装在凸板714上。
第二螺杆支座630的下端可设置有竖直插入孔，凸板714上可设置有能够插入第二螺杆支座630下部的插入孔中的销轴，使得第二螺杆支座630能够在凸板714上旋转。第二螺杆支座630中的竖直插入孔位于水平螺纹通孔的下方，从而避免插入第二螺杆支座630的下部的销轴与插入到水平螺纹通孔中的螺杆610相互干涉。
当螺杆驱动电机驱动螺杆610旋转时，螺杆610与第二螺杆支座630的啮合位置改变，推动第二螺杆支座630通过凸板714带动环形框架710旋转。
图7示出了第二导向单元2000的立体图，图8和图9示出了第二导向单元2000的俯视图。其中，在图8和图9中，为了更清楚地示出夹持单元800的结构，移去了环形框架710的上层部分(上层环形板)。下面，参照附图7-图9详细描述环形框架710的具体结构。
环形框架710可包括环形板和安装在环形板上的套筒761。为了稳定支撑并传递旋转力矩，环形板可包括同轴设置的在上层的第一环形板711和在下层的第二环形板712。中间连接板713将在上层的第一环形板711和在下层的第二环形板712连接为一体。中间连接板713可设置为多块，沿着环形框架710的轴向方向延伸，并在环形框架710的圆周方向上间隔设置。然而，在上层的第一环形板711和在下层的第二环形板712的连接方式不限于此，也可以采用多个连接柱将两者上下连接为一体的结构。
套筒761沿水平方向设置，可设置在第一环形板711和第二环形板712之间。在套筒761的上下两侧还可设置有套筒枢转轴762，套筒枢转轴762 沿竖直方向(与环形框架的轴线方向平行)延伸，一端与环形板结合，另一端与套筒761结合，从而套筒761能够通过套筒枢转轴762连接到环形板上，被环形板稳定地支撑，并能够围绕套筒枢转轴762旋转。在环形板旋转时，套筒761能够随着环形板在环形板的圆周方向上移动，同时还能够相对于环形板枢转，将转矩有效传递给夹持臂810。
夹持臂810可以为至少两个，在这种情况下，在夹持臂810的自由端可以设置弧形夹板，并且在弧形夹板的内侧可设置挤压滚轮，以在包围单桩基础的外周表面的一部分的同时，与单桩基础的外表面滚动接触。
在本公开的附图所示的示例中，第二夹持单元800包括三个夹持臂810，夹持臂810的第一端可枢转地连接到第二支撑平台160上。具体地，夹持臂铰接座820可固定安装到第二支撑平台160上，夹持臂810的第一端连接到夹持臂铰接座820上，从而能够围绕夹持臂铰接座820旋转。夹持臂810的第二端穿过套筒761，并从套筒761中伸出预定长度。夹持臂810的第二端可以连接有挤压滚轮812，以通过挤压滚轮812与单桩基础10的外表面滚动接触。夹持臂810可以为刚性直连杆，为了保证夹持臂810的强度，刚性直连杆可以设置为双层结构，即两个上下并联的直连杆用作一个夹持臂810。套筒761的截面可以为圆形也可以为方形，只要与夹持臂810的外形相适应并且不影响夹持臂810在套筒761中前后移动即可。
当螺杆驱动电机旋转时，螺杆610通过第二螺杆支座630推动环形框架710旋转，环形框架710通过套筒761带动夹持臂810围绕夹持臂枢转轴枢转，挤压滚轮812向着夹持空间或者远离夹持空间移动，从而调整可供单桩基础10穿过的空间大小。
当需要吊装单桩基础10以将单桩基础10插入到环形框架710中时，可以驱动挤压滚轮812向外移动，当单桩基础10已经插入到环形框架710中时，可以驱动夹持臂810枢转，通过挤压滚轮812在多个位置对单桩基础10施加挤压力，从而将单桩基础810抱紧。同样地，根据本公开第二实施例的第二导向单元能够通过一个驱动单元推动环形结构旋转，并通过环形结构推动三个夹持臂同步枢转，实现各个挤压滚轮812同步贴紧或松开单桩基础10的过程，实现同轴精确调节功能。
虽然在第二导向单元中采用丝杆驱动结构来实现第二驱动单元600，然而，第二驱动单元600不限于采用丝杆驱动结构，还可以采用齿轮-齿条驱动 结构。具体地，可以在环形框架710的外圈上设置齿轮，在第二支撑平台160上设置齿条，使齿条与齿轮啮合，通过使齿条前后移动，驱动齿轮旋转，从而带动环形结构旋转，同样能够通过单个驱动单元来使多个夹持臂同步操作。显然，驱动齿轮和驱动齿条的安装位置可以互换，只要能够驱动环形结构旋转即可。
根据本公开第二实施例的单桩基础导向装置，通过在竖直方向上设置第一导向单元和第二导向单元，两者可以同步工作，从而能够在上下两层同时进行垂直度调节，能够更准确地确保单桩基础的垂直度。此外，通过上下两层垂直度调节结构冗余设计，液压驱动和机械丝杠结构互为补充，如果其中一个调节结构出现故障，另一个调节结构也可实现高精度垂直度调节过程。
虽然在本公开第二实施例中，第一导向单元1000和第二导向单元2000上下设置，但是，第一导向单元1000和第二导向单元2000均可单独使用，均可实现同步调节单桩基础垂直度的功能。当设置上下多层导向结构时，不限于将第一导向单元1000和第二导向单元2000上下层布置，而是可以将多个第一导向单元1000上下布置，也可以将多个第二导向单元2000上下层布置，同样可以通过多层调节结构的冗余设计，确保单桩基础的精确垂直度导向功能。
根据本公开的实施例，与油缸设置在平台顶部的传统导向装置不同的是，根据本公开实施例的单桩基础导向装置的驱动单元设置在平台底部，操作人员在平台底部即可操作油缸和丝杆驱动结构，大大降低人员操作油缸坠海的风险。
根据本公开的单桩基础导向装置，能够在单桩基础的安装过程中对单桩基础起到导向、夹持和扶正的作用，确保单桩基础垂直打入海床，防止桩基在打桩过程中发生偏斜。在对单桩基础进行施加抱紧力时，对于每个导向单元，仅需通过操作单个驱动结构即可同时调整各个夹持臂的夹紧力，与传统的导向装置相比，能够省去单桩沉桩过程中需要停锤并多次测量单桩垂直度的步骤，大大提高沉桩效率。在采用多层导向单元同时进行导正的情况下，上下层导向单元可通过同轴同心实现同步操作，保证垂直度精准。结构简单，省去大量油缸，维护方便，结构成本低。
虽然已经参照本公开的示例性实施例具体示出并描述了本公开，但是本领域普通技术人员应该理解，在不脱离本公开的由权利要求限定的精神和范 围的情况下，可以在本公开中做出各种形式和细节上的改变。
