在本公开的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对 于本领域的普通技术人员而言，可以具体情况理解上述术语在本公开中的具体含义。
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本公开，而不能理解为对本公开的限制。
如图1～4所示，本实施例提供一种风力助推转子内塔，该风力助推转子内塔包括基座1、下塔体2、上塔体4、多个调节组件6和多个连接组件7。其中，下塔体2的底端设置于基座1，下塔体2的顶端设有下法兰3；上塔体4位于下塔体2的上方，上塔体4的底端设有上法兰5；多个调节组件6沿上法兰5的圆周方向间隔设置，调节组件6包括调节螺栓61，调节螺栓61螺接于上法兰5且抵接于下法兰3的顶面，以使上塔体4的上平面41的水平度位于预设范围内。多个连接组件7沿上法兰5的圆周方向间隔设置，连接组件7包括连接螺栓71和连接螺母72，连接螺栓71依次穿过上法兰5和下法兰3并与连接螺母72螺纹连接。具体地，上法兰5和下法兰3对应各个连接螺栓71均设有通孔，上法兰5对应各个调节螺栓61均设有螺纹调节孔，调节螺栓61螺接于螺纹调节孔，并且调节螺栓61的头端位于上法兰5上方，调节螺栓61的底端穿过螺纹调节孔并抵接在下法兰3的上表面，从而旋拧调节螺栓61即可调整上法兰5和下法兰3位于该调节螺栓61处的间距，通过旋拧各个调节螺栓61，则可对上塔体4与下塔体2之间的相对倾斜角度和倾斜方向进行调整，进而可对上塔体4的上平面41的水平度进行调整，当将上塔体4的上平面41的水平度调整至预设范围内时，可保证外筒旋转工作的平稳性。本实施例中，通过调节组件6对上塔体4上平面41的水平度进行调整，相比现有技术中于焊接工艺后期对转子内塔的上表面的水平度进行机加修整，效率高、工艺简单，能有效降低成本。
可以理解的是，当上塔体4的上平面41的水平度被调整至预设范围时， 其垂直度同样能够符合要求。本实施例中，预设范围为±2mm，在其他的实施例中，亦可根据需要进行设置。
本实施例中示例性地给出了上塔体4和下塔体2的横截面均为多边形的方案，在其他的实施例中，也可以根据需要将上塔体4和下塔体2的横截面均设置为圆形或其他形状。基座1、上塔体4和下塔体2均通过焊接工艺通过钢板焊接而成。优选地，上塔体4与上法兰5焊接成型，下塔体2与下法兰3焊接成型，下塔体2与基座1焊接成型。
可选地，多个调节组件6沿上法兰5的圆周方向均匀分布。多个连接组件7沿上法兰5的圆周方向均匀分布。由于多个调节螺栓61将上法兰5支撑于下法兰3，如此设置，能够保证各个调节螺栓61受力均衡。具体地，本实施例提供的风力助推转子内塔示例性地给出了调节组件6的数量为16个，连接组件7的数量为32个的方案，在其他的实施例中，亦可根据需要设置调节组件6和连接组件7的数量。
可选地，调节组件6还包括调节螺母62，调节螺母62螺接于调节螺栓61，且调节螺母62能够抵紧于上法兰5的上表面。通过设置调节螺母62，当调节螺母62旋松时，可通过旋拧调节螺栓61以调节上法兰5和下法兰3于该调节螺栓61处之间的间隙，当将调节螺母62相对上法兰5旋紧时，调节螺母62和上法兰5相对调节螺母62能够自锁，具有防松效果。优选地，调节组件6还包括垫圈63，垫圈63套设于调节螺母62且垫圈63位于调节螺母62和上法兰5的上表面之间，调节螺母62能够将垫圈63压紧于上法兰5。
可选地，连接螺母72为开槽螺母。将连接螺母72设置为开槽螺母，当连接螺栓71与开槽螺母螺接，且开槽螺母抵紧于下法兰3的下表面时，且开槽螺母上的槽能够产生形变，并可避免开槽螺母松动，具有防松的效果。
可选地，风力助推转子内塔还包括多个定位销8，多个定位销8沿上法兰5的圆周方向均匀分布，上法兰5和下法兰3上对应每个定位销8均设有 销孔，每个定位销8的两端分别与上法兰5上对应的销孔和下法兰3上对应的销孔销接。在组装时，可通过定位销8保证上法兰5和下法兰3准确对位。
可选地，风力助推转子内塔还包括调节垫片(附图中未示出)，调节垫片选择性设置于上法兰5和下法兰3之间，且调节垫片分别与上法兰5和下法兰3抵接。可以理解的是，调节垫片的厚度可具有多种尺寸规格，根据需要选择合适厚度尺寸的调节垫片塞入上法兰5和下法兰3之间，并且可沿上法兰5的圆周方向设置多个调节垫片，能够有效降低各个调节螺母62的受力，避免调节螺母62变形，以保证上塔体4上平面41的水平度和垂直度稳定。
该风力助推转子内塔的装配工艺如下：
1)、分别制作上塔体4、下塔体2和底座，并在上塔体4的底端焊接上法兰5，下塔体2的顶端焊接上法兰5。
2)、将上法兰5和下法兰3对接，并使各个定位销8分被插入上法兰5和下法兰3上对应的销孔。
3)、将各调节螺母62和垫圈63分别旋入对应的调节螺栓61，并将调节螺栓61分别旋入上法兰5上对应的螺纹调节孔内，采用扳手依次旋动各个调节螺栓61，使得调节螺栓61的螺杆上下移动，通过螺杆底部与下法兰3面相互作用来调节上塔体4的上平面41的水平度，同时在上塔体4的上平面41上放置水平仪来检测，并根据检测结果在上法兰5和下法兰3之间塞入不同厚度的调节垫片，并将旋拧各个调节螺母62，以使调节螺母62将对应的垫圈63压紧在上法兰5的上表面，可保证上塔体4的上平面41的水平度和垂直度在2mm以内。
4)、将各个连接螺栓71依次穿过上法兰5和下法兰3上对应的通孔，并与对应的连接螺母72螺纹连接，将上法兰5和下法兰3锁紧连接。
显然，本公开的上述实施例仅仅是为了清楚说明本公开所作的举例，而并非是对本公开的实施方式的限定。对于所属领域的普通技术人员来说，在 上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本公开的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本公开权利要求的保护范围之内。
