为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
如下图1至3所示，主泵转速探针1固定于主泵主轴2上，可以随主泵主轴2转动，优选地，探针1设置在主泵主轴2的外壁面上。
本申请的一个实施例中构造了一种主泵转速传感器探针定位装置，定位装置包括安装组件31和探针模拟器32。探针模拟器32包括定位件321、基座322、调整件323，定位件321上设有定位头B，定位件321设置于基座322上，调整件323用于驱使定位件321在基座322上沿主泵主轴2的轴向和径向移动，以使得定位件321能够抵接探针1的端部和侧壁。
本实施例中，为了方便对探针1的端部及底面、顶面定位，定位头B呈L形，包括依次弯折的第一段、第二段，第一段能够抵接探针1的端部，第二段能够抵接探针1的侧壁，通常，定位头B夹角内侧的两侧面可以分别对探针1的端部及底面定位，或者分别对探针1的端部及顶面定位。
L形的定位头B外形规则，尺寸易管控，能提升对探针1的定位精度。在其他实施例中，定位件321的定位头B的外形也可为其他形成，在定位头B上可形成第一定位区B1、第二定位区B2，第一定位区B1对探针1的端部定位，第二定位区B2对探针1的底面或顶面定位。第一定位区B1、第二定位区B2可以为平面，也可为曲面或尖头结构。当然，定位头B的外形也可呈U形，U形开口内的三个面能分别对探针1的端部、底面、顶面定位。
定位件321采用316不锈钢材料，加工精度为5um。316不锈钢材料，防锈防腐、高强度防磕碰；零件极少化设计，消除了部件内部的装配误差；实现了小型化、高精度及高可靠性设计。
在探针模拟器32沿主泵主轴2的轴向和径向移动时，定位头B分别对探针1的端部，以及探针1的底面定位。当然，定位头B也可分别对探针1的端部、以及探针1的顶面定位，或分别对探针1的端部、以及探针1的顶面、底面定位。采用定位头B，可以确定在冷停工况下，在定位了探针1与定位件321的相对位置后，确定了探针1与主泵主轴2的相对位置，结构简单，定位方式简便快捷，提升了定位效率。
在一些实施例中，安装组件31环设于主泵主轴2外周，用于与主泵主轴2的端面和外圈定位，形成相对主泵主轴2相对位置固定的定位基准，为探针模拟器32的安装提供定位基准。探针模拟器32滑动安装到安装组件31上，该探针模拟器32能够沿安装组件31绕主泵主轴2的轴线做圆形转动，从而能相对主泵主轴2上的探针1做转动，在转动至探针1位置时，可以作为基准对探针1进行定位。
在一些实施例中，安装组件31包括环形围圈311和安装脚312，进一步地，环形围圈311的内圈尺寸与主泵主轴2的外圈尺寸相当，以与主泵主轴2的外壁面定位，环形围圈311可以作为外壁面的基准参考，另外，安装脚312为多个，沿环形围圈311的周向分布，与环形围圈311连接，以与主泵主轴2的端面定位，让安装脚312作为主泵主轴2端面的定位。
安装组件31同时与主泵主轴2下端的外壁面、端面定位，能为探针模拟器32的定位提供多向参考，定位更准确。在其他实施例中，安装组件31也可同时与主泵主轴2上端的外壁面、端面定位。
在本实施例中，环形围圈311和安装脚312均采用磁性吸附的方式定位到主泵主轴2上，当然，在其他实施例中，也可只将环形围圈311采用磁性吸附的方式定位，或者只将安装脚312采用磁性吸附的方式定位，能保证安装组件31的定位稳定可靠即可。在本实施例中，环形围圈311和安装脚312上均设有供磁铁安装的安装槽A，环形围圈311的外壁面上沿周圈间隔分布有若干安 装槽A，让磁铁侧向卡入。
优选地，安装脚312沿环形围圈311的径向延伸设置，让安装脚312的分布更均匀，受力更稳定。进一步地，在本实施例中，环形围圈311包括沿周向分布的四段弧形围台3111，各围台3111沿周向拼接成圆环形，每一围台3111上设有两个安装脚312。可以理解地，在其他实施例中，环形围圈311也可包括沿周向分布的两段或两段以上的其他数量的弧形围台3111，各弧形围台3111沿周向拼接成环形，每一围台3111上的安装脚312的数量也可为一个或一个以上的其他数量。
进一步地，安装脚312可以与环形围圈311为一体结构，当环形围圈311分段设置时，安装脚312也可与弧形围台3111为一体结构。优选地，每瓣弧形围台3111为单一零件，弧形围台3111与主泵主轴2侧面磁吸，与弧形围台3111一体化设计的安装脚312与主泵主轴2底面磁吸，弧形围台3111采用316不锈钢材料，加工精度为5um，能够防锈防腐、高强度防磕碰，零件数量极少化设计，消除了部件内部的装配误差；实现了小型化、高精度及高可靠性设计。
优选地，安装组件31为了保证安装精度，安装组件31采用整体加工制造且材质相同的316不锈钢，避免放置或者移动过程发生较大幅度的形变。
优选地，为了保证探针模拟器32的运动轨迹准确，在安装组件31上设有供探针模拟器32滑动安装的导向结构，供探针模拟器32沿安装组件31绕主泵主轴2的轴线做圆形转动，通常，探针模拟器32与导向结构滑动配合，让探针模拟器32的转动更顺畅，使得探针模拟器32在移动过程中，保证该探针模拟器32的轴向高度以及径向位移变化在可控范围内，不发生明显变化。
进一步地，导向结构可拆卸安装在安装组件31上，便于组装。在本实施例中，导向结构磁性吸附到安装组件31上，提升吸附的稳定性。优选地，导向结构为在环形围圈311上沿主泵主轴2的周圈设置的环形导轨，在一些实施例中，导向结构可拆卸安装在环形围圈311上，当然，导向结构也可直接形成于环形围圈311上，如导向槽。
再结合图1至图4所示，本申请还构造了一种主泵转速传感器探针模拟 转动装置，用于模拟主泵主轴2上的探针转动。进一步地，模拟转动装置包括定位组件31、探针模拟器32，安装组件31环设于主泵主轴2的外周。探针模拟器32包括定位件321、基座322、调整件323，定位件321安装在调整件323上，调整件323活动安装在基座322上，用于驱使定位件321沿主泵主轴2的径向和轴向移动，以与探针定位。
基座322滑动安装到安装组件31上，用于带动定位件沿安装组件滑动。由于探针模拟器32可以沿安装组件31绕主泵主轴2做圆形转动，使得探针1和模拟转动装置之间产生相对转动，来模拟探针1转动。
模拟转动装置的探针模拟器32相对主泵主轴2上的探针1做转动，相对探针1产生相对转动，可以模拟探针1的转动，利用两者之间转动时的相对位置，从而判断探针1的定位是否准确，该过程可以在主泵主轴2停机状态下进行，提升了效率。
优选地，调整件323磁性吸附定位到基座322，利用磁性吸附定位，进一步地，调整件323还可嵌设到基座322上，采用嵌设和吸附的方式结合，定位准确，稳定性好。可以理解地，也可单独采用磁性吸附或嵌设的方式定位。
当采用磁性吸附的方式定位时，磁铁可以分布设置，让磁性吸力更均匀、更平衡。进一步地，采用磁性吸附，具有以下效果：
1、相互磁吸的两个零件的接触面完整、平滑，可以消除对磁吸效果及移动效果的干扰；
2、磁吸力分布均匀、磁吸力大小可调整，吸附可靠，便于安装、拆卸，以及探针模拟器32的移动；
3、在小型化、保证强度的前提下，可以减轻零件重量，有益于轻量化设计。
探针模拟器32的基座322也采用316不锈钢材料，加工精度为5um；基座322的下端面与环形围圈311也采用磁吸方式安装。基座322与主泵主轴2配合的面采取与主泵主轴2圆周面的拟合设计，基座322底部设计有与主泵主轴2圆周面对应的嵌入式、分布式、可编程的片状磁铁仓C，以及与环形围圈311磁吸的软铁带仓，考虑到安装好的探针模拟器32应便于沿主泵主轴2圆 周平滑移动，另外，环形围圈311上设计有嵌入式片状磁铁，所以与环形围圈311有磁吸要求的基座322的对应部分，就不能再用磁铁了，而是采用软铁带。
一些实施例中，参见图3及图4，调整件323包括第一活动座3231、第二活动座3232，第一活动座3231与基座322之间能够沿主泵主轴2的轴向移动，第二活动座3232与第一活动座3231之间能够沿主泵主轴2的径向移动，第二活动座3232上安装有定位件321。
进一步地，基座322上设有用于为第一活动座3231导向的第一导向结构，以使得第一活动座与基座之间可以相对移动，第一活动座3231上设有用于为第二活动座3232导向的第二导向结构，以使得第二活动座和第一活动座之间可以相对移动，当调节第一活动座和第二活动座时，从而能实现定位件321的位置调节，便于调节定位件321的位置以对探针1进行定位。
优选地，第一导向结构沿主泵主轴2的轴向导向，第二导向结构沿主泵主轴2的径向导向，一个为沿主泵主轴2的轴向导向，另一个为沿主泵主轴2的径向导向，可以实现定位件321在不同方向的位置调节，让调节更加准确灵活，例如，第一导向结构包括设置于基座和第一活动座之间的导轨，该导轨沿主泵主轴2的轴向延伸，从而使得第一活动座相对于基座之间可以沿主泵主轴2的轴向往复移动，从而带动定位件沿主泵主轴2的轴向往复移动；第二导向结构包括设置于第二活动座和第二活动座之间的导轨，该导轨沿主泵主轴2的径向延伸，从而使得第二活动座相对于第一活动座沿主泵主轴2的径向往复移动，从而带动定位件沿主泵主轴2的径向往复移动。在其他实施例中，第一导向结构、第二导向结构的导向方向也可呈夹角，便于在不同方向调节定位件321的位置。
当然，在其他实施例中，第一导向结构为导槽，也可为导槽和导轨的组合，能提供稳定的导向即可。进一步地，第二导向结构为导槽，也可为导槽和导轨的组合，以能提供稳定的导向。
探针模拟器32还包括测量组件324，测量组件324还包括用于带动第一活动座3231移动的第一调节件3241，以及用于带动第二活动座3232移动的第二调节件3242，在带动第一活动座3231、第二活动座3232移动时，实现驱 动定位头B移动。第一调节件3241转动设置在基座上，并与第一活动座转动配合，第二调节件3242转动设置在第一活动座上，并与第二活动座转动配合。
探针模拟器32的测量组件324可以选用的小型化的精密云台，型号通常为LE40-L，可以用来检测基座322和调整件323的活动位移，该云台的运动范围为10mm。在本实施例中，第一调节件3241、第二调节件3242可以分别为两个云台上的旋钮，通过转动旋钮，实现调整件323上定位件321的位置调节移动。用数字测微计DMH-1替换测量组件324的云台原有的螺旋千分尺，通过转换器DMH-DL-U与显示器通讯，用具有数字接口的数字测微计，实现多维间隙的测量值集中数显，让第一调节件3241、第二调节件3242在调节过程中，还能测量定位件321的移动位移。
如图4所示，进一步地，为了便于模拟转动装置定位，提升定位的准确性，在基座322上设有与主泵主轴2的外壁面配合的定位面D，利用主泵主轴2的表面定位，基准稳定，不易出现偏差。
优选地，基座322上的定位面D为弧面，且与主泵主轴2的外壁面外形匹配，依靠定位面D贴合到主泵主轴2的外壁面，实现定位。在其他实施例中，基座322上的定位面D也可设置若干定位凸起，且各凸起能分别贴合到主泵主轴2的表面，实现基座322的定位。
进一步地，安装组件31与主泵主轴2的端面和外圈定位，基座322磁性吸附到安装组件31上，基座322还依靠安装组件31实现定位，让定位更稳定可靠。
当探针模拟器32完成对探针1的定位后，则可以通过转速传感器4，来完成对探针1转动转速的检测。通常，转速传感器4采用磁阻式测量原理，转速传感器4上设有感测槽41，在本实施例中，感测槽41呈U型，在对探针1测转速测量时，转速传感器4的感测槽41位于与主泵主轴2相对的一端，感测槽41沿主泵主轴2的周向贯穿，优选地，感测槽41的宽度大于探针1的厚度，可供探针1、以及对探针1定位的定位头B转动过程中卡入后同时通过。
结合图5至图8所示，本申请还公开了一种主泵转速传感器调校装置，用于对主泵主轴的转速传感器进行调校，主泵主轴2的外壁面上设置有探针1， 转速传感器4与主泵主轴2相对的一端设有沿周向贯穿的感测槽41，感测槽用于供探针转动通过。
调校装置包括安装支架5和探针模拟器32，安装支架5设置在主泵壳体上，并用于安装转速传感器4，让转速传感器4检测探针1随主泵主轴2转动的转速。探针模拟器32包括对探针1定位的定位头B以及测量组件324，定位头转动通过感测槽，测量组件324用于获取定位头B至感测槽41的轴向内侧壁以及径向底壁的距离。
主泵转速传感器4固定于安装支架5上，处于静止状态，当主泵主轴2转动带动探针1切割转速传感器4时会产生一个脉冲信号，所以主泵正常运行时，转速传感器4会产生一个特定的频率信号，通过此信号测量实现主泵转速的测量。优选地，安装支架5安装在泵体上，借用泵体进行支撑，可以让安装支架5的安装更稳定，进一步地，安装支架5在泵体上的位置可调，进而在调节安装支架5的位置时，调节转速传感器4相对探针1的位置。
探针1以及定位头B转动通过感测槽，通过调节测量组件324的第一调节件3241、第二调节件3242，让定位头B移动，在移动的同时，测量组件324可以测量定位头B的移动位移，得到移动前后的相对位置，测量组件324获取定位头B至感测槽41的轴向内侧壁、径向底壁的距离。
优选地，转速传感器4在安装支架5上的位置可调，可以调整转速传感器4相对探针1、定位件321的位置，保证转速传感器4和探针1之间的相对位置准确，满足转速传感器4对探针1进行正常的转速检测。
在一些实施例中，转速传感器4上设有第一安装孔42，第一锁合件穿过第一安装孔42后锁合到安装支架5，第一锁合件与第一安装孔42之间间隙配合，可以让转速传感器4相对第一锁合件侧向调节位置，以让转速传感器4满足与探针1之间的相对位置需求。
进一步地，在本实施例中，第一安装孔42的轴向方向与感测槽41的贯穿方向相同，由于第一安装孔42与第一锁合件之间间隙配合，可以让转速传感器相对第一锁合件的不同侧偏移，从而让转速传感器4相对探针1调节在水平方向和竖直方向的位置，同时，还可调节转速传感器4的摆动方向。
优选地，安装支架5上设有第二安装孔51，第二锁合件穿过第二安装孔51后锁合到泵体上；第二锁合件与第二安装孔51之间间隙配合，可以让转速传感器4相对第二锁合件侧向调节位置，以让转速传感器4满足与探针1之间的相对位置需求。
进一步地，为了能实现多向调节，第一安装孔42的轴向与第二安装孔51的轴向呈夹角，且第二安装孔51的轴向与主泵主轴2的轴向方向相同，可以让转速传感器4可以相对探针1调节在水平方向的位置，同时，还可调节转速传感器4的摆动方向。通常，由于主泵转速探针1与主泵转速传感器4之间的相对位置直接影响测量的准确性和稳定性，所以对主泵转速探针1与主泵转速传感器4的安装具有严格的要求。
盘动主泵主轴2将主泵转速探针1置于主泵转速传感器4的感测槽41中间位置，需对其间隙进行测量，测量间隙包括感测槽41上间隙、感测槽41下间隙和探针1与感测槽41底部间隙，以判断是否满足安装标准要求。
进一步地，本申请另一实施例中还公开了一种主轴转速传感器4安装方法，包括以下步骤：
将探针模拟器32绕主泵主轴2的轴线做圆形转动，至转速传感器4的感测槽41内；
调节安装支架5的位置，在探针模拟器32的定位头B和感测槽41与主泵主轴2相对的侧面接触时，锁定安装支架5，得到感测槽顶部间隙dx；
在定位头B和感测槽41的下侧面接触时，得到感测槽下间隙hdy；
在定位头B和感测槽41的上侧面接触时，得到感测槽上间隙huy；
确认感测槽上间隙huy、感测槽下间隙hdy满足要求，否则调整转速传感器4的上下位置，至感测槽上间隙huy、感测槽下间隙hdy满足要求后，锁定安装支架5。

多基地核电机组主泵转速传感器4的安装调整窗口为一回路压力2.5Mpa平台，此工作在换料大修主线路径上，直接影响换料大修工期和机组发电量；如果将其优化调整至冷态窗口，即一回路压力0Mpa平台执行，可以节约3个小时左右换料大修主线时间，有效提高核电机组发电量，具有显著的经济和社会效益。
