在风力发电机进行组装或对叶轮中各部件进行维护时， 需要首先将叶轮 制动， 使其停止旋转， 并锁定， 保证叶轮的位置固定， 维护人员再进入叶轮 进行维护作业。
目前， 通常采用锁定销进行叶轮的锁定， 应用较为广泛的为液压式叶轮 锁定装置。 如图 1所示， 叶轮与叶轮联接盘 1的相对位置固定， 叶轮联接盘 1通过第一主轴承 2和第二主轴承 3可旋转地安装在风力发电机的基座 10上， 基座 10与旋转轴 12固定结合； 在叶轮联接盘 1的端部固定连接有发电机转 子 7， 而发电机定子 6固定连接在基座 10上， 叶轮联接盘 1带动发电机转子 7相对于发电机定子 6转动， 从而实现能量的转换。 在基座 10上固定有制动 器 11， 该制动器 11还位于叶轮联接盘 1的边缘， 以便制动叶轮联接盘 1。 在 叶轮联接盘 1上设置有锁定套 4， 锁定套 4具有锁定孔 401， 与锁定孔 401相 配合的锁定销 5连接在基座 10上，在锁定销 5上安装有推动其运动的活塞 8， 活塞 8进一步由与基座 10固定连接的锁销安装板 9支撑。
在对叶轮进行维护时， 当叶轮联接盘 1的转速低于 lrpm时， 制动器 11 开始制动， 将叶轮联接盘 1 的边缘夹紧， 利用两者之间的摩擦力使叶轮联接 盘 1停止转动， 尽量使叶轮联接盘 1在停止转动时， 锁定孔 401的轴线与锁 定销 5的轴线对准， 再对叶轮进行锁定； 在锁定时， 液压油进入锁定销 5的 前腔， 进而在液压作用下将锁定销 5推入锁定孔 401中， 将叶轮联接盘 1和 基座 10固定连接在一起， 实现叶轮的锁紧定位。 而在需要解锁时， 液压油进 入到锁定销 5的后腔，同时锁定销 5从锁定套 4中脱离，并且制动器 11松开， 叶轮便可再次转动。
锁定销 5的外形为圆锥台形， 相应地， 锁定套 4上的锁定孔 401也是圆 锥台形孔， 如图 2所示。 在叶轮制动后， 若锁定销 5与锁定孔 401的轴线并 未完全对准时， 由于在两者的相邻表面之间存在一定的径向间隙， 使得在这 种情况下， 锁定销 5的圆锥台头部也能被推入至锁定孔 401中， 以使两者的 轴线完全对准； 在锁定销 5完全推入锁定套 4中后， 锁定销 5的圆锥台头部 与锁定孔 401完全贴合。
在上述锁定过程中， 叶轮联接盘 1只有一个周向的自由度， 只要锁定销 5和锁定孔 401的轴线对准， 锁定销 5便可顺利地推入锁定套 4中， 完成对 叶轮的锁定。 但是在加工和安装过程中不可避免地存在误差， 导致锁定销 5 和锁定套 4的轴线总会存在一定的径向误差， 如图 3所示， 使得对叶轮的锁 定变得较为困难。 且锁定销 5在被推入锁定孔 401中的过程中， 会受到较大 的侧向力， 甚至导致锁定销 5的圆锥台头部发生变形， 这样在需要解除锁定 时， 锁定销 5极有可能不能顺利地从锁定套 4中退出， 出现锁定销 5卡死的 现象， 导致风力发电机不能正常运行， 这时便需要拆卸锁定销 5， 拆卸过程 困难且可能需要数天时间， 从而增加了维护成本， 且数天停机将造成发电损 失。 此外， 在锁定销 5卡死时， 导致主轴承的径向载荷增大， 可能造成主轴 承的损伤， 降低了主轴承的使用寿命。
因此， 如何顺利完成叶轮的锁定， 并避免锁定销卡死的现象是本领域技 术人员需要解决的技术问题。 发明内容
本发明的目的在于提供一种用于风力发电机的叶轮锁定装置， 实现对叶 轮的锁定， 并避免锁死的现象。 此外， 本发明的另一个目的在于提供一种包 括上述叶轮锁定装置的风力发电机。
为实现上述目的， 本发明提供了一种叶轮锁定装置， 所述叶轮锁定装置 包括设置在叶轮联接盘上的锁定孔以及与所述锁定孔相配合的锁定销， 所述 锁定销与风力发电机的基座连接， 当所述锁定孔与所述锁定销锁定时， 所述 锁定销和所述锁定孔在所述叶轮联接盘的径向上具有径向间隙， 以便所述锁 定销能够相对于所述锁定孔沿所述叶轮联接盘的径向不接触。

本发明所提供的叶轮锁定装置通过所述锁定销和所述锁定孔之间的径向 间隙，在所述锁定销和所述锁定孔的轴线之间存在一定的径向偏移的情况下， 也可实现对叶轮的锁定， 从而解除了锁定过程中的径向约束。 此外， 在锁定 过程中， 所述锁定销和所述锁定孔均不会发生变形， 不会出现卡死的现象， 即不会发生锁定销不能退出的现象， 也能避免对主轴承产生额外载荷。
在另一种优选的实施例中， 本发明所提供的叶轮锁定装置还包括用于限 定所述锁定销周向运动的限位装置。 在所述限位装置的作用下， 使所述锁定 销的外周始终位于所述锁定孔的外周范围之间， 避免了由于所述锁定销的周 向转动引起不能正常插入锁定孔中的现象。
在实施本发明新的销定销之后， 当安装锁定套时，不再需要冷冻箱冷冻， 不需要盘车电瓶车， 不需要同轴调试， 从而可以简化安装工艺， 缩短装配时 间及降低装配成本。
此外， 本发明所提供的风力发电机具有与上述叶轮锁定装置相同的技术 效果， 在此不再赘述。 附图说明

现在对本发明实施例进行详细的描述， 其示例表示在附图中， 其中， 相 同的标号始终表示相同部件。
下面通过参照附图对实施例进行描述以解释本发明。
参照图 4， 图 4为根据本发明的实施例的叶轮锁定装置的结构示意图。 在根据本发明的一种实施例中， 风力发电机包括通过第一主轴承 2和第 二主轴承 3可旋转地安装在风力发电机旋转轴 12的基座 10上的叶轮联接盘 1。 叶轮联接盘 1进一步与风力发电机的发电机转子 7连接， 以带动发电机转 子 7相对于发电机定子 6旋转， 将风能转化为电能。 在叶轮联接盘 1上形成 有锁定孔 401， 与锁定孔 401相配合的锁定销 5安装在锁定孔 401的下方， 并与风力发电机的基座 10连接。
锁定销 5可以设置在基座 10与发电机定子 6之间，活塞 8通过锁销安装 板 9与基座 10固定连接，活塞 8与锁定销 5构成的前后两个油腔中填充有液 压油， 锁定销 5在液力的驱动下能够在锁定孔 401中上下运动。 也就是说， 锁定销 5可以具有两个自由度， 上下的直线运动以及周向转动的自由度。
在锁定销 5的上端部为与锁定孔 401相配合的推入端， 在推入端完全被 推入到锁定孔 401中时， gp， 锁定销 5与锁定孔 401锁定时， 锁定销 5与锁 定孔 401在叶轮联接盘 1的径向上存在径向间隙， 从而使得锁定销 5相对于 锁定孔 401能够沿叶轮联接盘 1的径向不接触， 也就是说， 锁定销 5能够相 对于锁定孔 401沿叶轮联接盘 1的径向运动。
此外， 在叶轮联接盘 1上可以进一步安装有锁定套 4， 而锁定孔 401开 设在锁定套 4上。 锁定套 4可采用强度比叶轮联接盘 1更高的材料制成。 这 样， 可以避免锁定销 5与叶轮联接盘 1直接接触， 避免在锁定时锁定销 5对 叶轮联接盘 1造成损伤。
锁定孔 401以及与其相配合的锁定销 5的具体形式较多。 例如， 锁定销 5与锁定孔 401相配合的端部 （BP , 推入端） 可以为楔形 （当然， 该楔形为 从下到上渐窄的楔形）， 如图 5所示， gp， 锁定销 5具有四个外表面， 其中两 个相对的外表面平行于叶轮联接盘 1 的径向， 另外两个相对的外表面垂直于 叶轮联接盘 1的径向， 而锁定孔 401可以为允许锁定销 5插入的各种形状， 只要两者之间存在径向间隙并且锁定销 5能够在叶轮联接盘 1的径向上不接 触即可。 在这种情况下， 锁定销 5的四个外表面中的一个外表面或多个外表 面可以为倾斜的表面。 在一种实施例中， 锁定销 5的与叶轮联接盘 1的径向 平行的两个外表面可以为倾斜表面， 而锁定孔 401可以为与锁定销 5相适应 的楔形或者也可以为圆柱形， 从而在插入锁定销 5的过程中锁定销 5与锁定 孔 401在与叶轮联接盘 1的径向垂直的方向上具有一定的间隙， 因此， 锁定 销 5能够被容易地插入到锁定孔 401中。
除了上述具体形式以外锁定销 5 与锁定孔 401 相配合的端部和锁定孔 401 的横截面均可以为长方形， 这样， 锁定销 5与锁定孔 401可均呈长方体 状。 类似地， 在不影响正常锁定的情况下， 锁定销 5的尺寸可略小于锁定孔 401的尺寸， 以使锁定销 5容易地插入到锁定孔 401中。
对于上面的各种具体形式， 当锁定销 5被推入到锁定孔 401中， 在相同 横截面上， 在叶轮联接盘 1的径向上， 锁定销 5的长度小于锁定孔 401的长 度， 以保证锁定销 5的外表面和锁定孔 401的表面在径向上存在一定的间隙， 如图 6所示； 在与叶轮联接盘 1的径向垂直的方向上， 与上述各种具体形式 不同的是， 锁定销 5的尺寸 （或长度）还可以与锁定孔 401的尺寸（或长度） 相同， 如图 7或 8所示， 从而锁定销 5在该方向上与锁定孔 401完全贴合， 两者之间的接触面积最大， 因此， 有助于提高锁定的稳定性和可靠性。
在本发明中， 所提供的叶轮锁定装置包括多组相配合的锁定销 5和锁定 孔 401， 这些锁定销 5的形状可以相同， 且这些锁定孔 401 的形状也可以相 同， 并且在每组相配合的锁定销 5和锁定孔 401之间在叶轮联接盘 1的径向 上均存在径向间隙， 并且锁定孔 5均能够相对于各自的锁定孔 401在径向上 不接触， 以便于所有的锁定销 5同时顺利地插入到锁定孔 401中。
当需要对叶轮进行锁定时， 先使风力发电机停机， 待叶轮联接盘 1的转 速低于 lrpm时， 利用制动器 11将叶轮联接盘 1制动， 并最好使叶轮联接盘 1制动后， 锁定孔 401的轴线与锁定销 5的轴线对准。 操控活塞 8， 使液压油 进入锁定销 5的前腔， 利用液力， 将锁定销 5推入到锁定孔 401中， 实现对 叶轮联接盘 1的锁定。
若在叶轮联接盘 1制动后， 由于加工或安装误差等因素导致锁定孔 401 的轴线与锁定销 5的轴线之间存在径向偏移时， 由于在锁定孔 401和锁定销 5之间存在径向间隙， 在径向偏移的情况下使锁定销 5仍能够被推入锁定孔 401中， 将叶轮联接盘 1锁定， 从而解除了锁定过程中的径向约束。
本发明所提供的叶轮锁定装置通过在锁定销 5和锁定孔 401之间设置径 向间隙， 从而保证了在两者的轴线存在径向误差的情况下， 锁定销 5也能顺 利地被推入锁定孔 401中。 此外， 锁定销 5在推入或锁定过程中不会变形， 从而避免了锁定销 5卡死的现象， 并在一定程度上有助于降低主轴承所承受 的侧向力， 提高主轴承的使用寿命。
在锁定销 5和锁定孔 401的形状为楔形或其他非回旋形状时， 由于锁定 销 5具有周向自由度，可以不受控制地旋转，所以即使锁定销 5与锁定孔 401 的轴线对准， 锁定销 5的外表面与锁定孔 401的内表面也有可能会存在一定 的角度误差。 这种情况下， 若两者之间的角度误差不是太大， gP， 锁定销 5 的外周在轴向视角下位于锁定孔 401的内周范围之内， 则锁定销 5在推入过 程中通过与锁定孔 401之间的接触能够自动调整自身的角度， 从而当完全被 推入到锁定孔 401中时其外表面与锁定孔 401的表面相配合。
但是， 若锁定销 5相对锁定孔 401错开的角度较大时， gp， 锁定销 5的 外周的一部分位于锁定孔 401 内周范围之外时， 例如， 当两者处于如图 9所 示的位置关系时， 锁定销 5极有可能不能顺利地被推入锁定孔 401中。为此， 在根据本发明的另一实施例中， 叶轮锁定装置进一步包括限位装置， 用于限 定锁定销 5的周向转动， 以保证锁定销 5始终位于锁定孔 401的范围内。 这 里所述的限定包括两层含义， 一是锁定销 5被锁定在某一周向位置不动， 仅 能够上下运动， 二是所述锁定销 5可以在小范围内自由转动。 进一步， 限位 装置设置在锁定销 5和与基座 12固定连接的锁销安装板 8上。
具体地， 限位装置可以包括限位杆 13， 限位杆 13贯穿锁销安装板 8， 且 其顶端插入在锁定销 5的底端， 并与锁定销 5固定连接。 此外， 限位杆 13应 具有一定的长度， 在限位杆 13随锁定销 5调整至合适的锁定位置后， 其底端 不会从锁销安装板 8中脱离。如果这样的限位杆 13只有上下直线运动的自由 度， 那么相应地， 锁定销 5便会被锁定在某一周向位置。 对于锁定销 5被锁 定在某一周向位置不动的情况， 本发明所提供的限位装置并不限于此， 还可 以为其他形式。 例如， 限位装置可以为螺栓， 螺栓的顶端直接旋紧在锁定销 5上， 底端横穿锁销安装板 8， 或者在不会影响锁定销 5正常的向上推入和锁 定的情况下螺栓的底端连接到基座 10 合适部位也是可以的。 此外， 限位杆 13与锁销安装板 8之间也可以为固定连接， 并且该限位杆 13的长度可调， 例如， 为伸缩杆， 以便不会限制锁定销 5的正常推入。
为方便限位杆 13的安装， 在锁销安装板 8上开设的用于安装限位杆 13 的限位孔的直径可以稍大于限位杆 13的直径。这样， 允许锁定销 5在小角度 范围内旋转， 如图 10所示。 当然， 锁定销 5在转动到最大角度时， 其外周也 应该位于锁定孔 401的内周范围之内； gp， 该角度不会影响锁定销 5的正常 推入和锁定。
此外， 为了保护限位杆 13， 还可以在限位杆 13的底端安装防护罩 14。 在限位装置的作用下， 锁定销 5不会发生较大角度的旋转或者锁定销 5 不动， 即使锁定销 5发生如图 10所示的小角度的旋转后， 在锁定销 5正常的 推入过程中，会对自身的角度进行调整， 以使锁定销 5的外表面与锁定孔 401 的内表面完全配合， 如图 11所示， 此时， 限位杆 13与锁销安装板 8上的限 位孔同轴。
此外， 本发明还提供一种风力发电机， 该风力发电机包括基座， 在基座 上连接有上述叶轮锁定装置， 所述风力发电机具有与上述叶轮锁定装置相一 致的优点和特征； 风力发电机的其他结构请参考现有技术， 在此不再赘述。
上面对本发明所提供的风力发电机及用于风力发电机的叶轮锁定装置进 行了详细描述， 虽然已表示和描述了本发明的一些实施例， 但本领域技术人 员应该理解， 在不脱离由权利要求及其等同物限定其范围的本发明的原理和 精神的情况下， 可以对这些实施例进行修改和完善， 这些修改和完善也应在 本发明的保护范围内。
