在本公开的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。
下面参考附图描述根据本公开实施例的道岔转辙驱动机构100。
参照图1所示，根据本公开一个实施例的道岔转辙驱动机构100可包括多个驱动单元110，多个驱动单元110可沿道岔梁200的延伸方向间隔开设置。这里，道岔梁的延伸方向可以理解为道岔梁的长度方向，例如，如图1中所示的前后方向。在本公开的描述中，除非另有说明，“多个”的含义是两个或两个以上，例如，三个、四个等。例如，如图1所示，驱动单元110可以为四个。
如图2和3所示，每个驱动单元110可包括移动台架10、固定导向件20和驱动装置30。移动台架10通过第一移动副101和转动副103与道岔梁200相连，也就是说，移动台架10与道岔梁200相连，并且可以通过第一移动副101的移动相对于道岔梁200移动，还可以通过转动副103的转动相对于道岔梁200枢转。
进一步地，第一移动副101的移动方向为道岔梁200的延伸方向，转动副103的枢转轴线沿竖直方向延伸(例如，如图1和图3中所示的上下方向)。由此，移动台架10可沿道岔梁200的延伸方向移动，并且还可以绕大体沿竖直方向延伸的枢转轴线向相对于道岔 梁200枢转。
移动台架10可通过第二移动副102与固定导向件20相连，也就是说，移动台架10与固定导向件20相连，并且可以通过第二移动副102的移动相对于固定导向件20可移动。可选地，固定导向件20可固定设置，可以安装到地面或者支架等结构上，此时，移动台架10相对于地面可以移动。
第二移动副102的移动方向与道岔梁200的延伸方向相交。也就是说，第二移动副102的移动方向与道岔梁200的延伸方向形成不为零的夹角，此时，移动台架10在垂直于道岔梁200的延伸方向上可以具有一定的位移，也就是说，移动台架10在道岔梁200的宽度方向(例如，如图1中所示的左右方向)上的可以移动一定的距离。其中，所述夹角的大小可以根据需要进行设置，例如，可以设置为30度-90度之间的任意角度，如30度、45度、60度、75度或90度等。
驱动装置30可与第二移动副102相连，以驱动第二移动副102活动。当第二移动副102活动时，移动台架10相对于固定导向件20可以移动，并且可以带动第一移动副101和转动副103活动，从而可以使道岔梁200移位。在道岔梁200的延伸方向上从后向前(如图1中所示的前后方向)，多个第二移动副102在各自的驱动装置30的驱动下在道岔梁200的宽度方向上的位移递增。
由此，多个第二移动副102在与道岔梁200垂直的方向(例如，如图1中所示的左右方向)上的移动距离呈递增状态，使得在道岔梁200的延伸方向上从后向前道岔梁200的位移递增，可以实现道岔转辙动作。
根据本公开实施例的道岔转辙驱动机构100，通过设置两个移动副和一个转动副以及用于提供驱动动力的驱动装置30，使得移动台架10可以沿直线运动并且使道岔梁200可以在移动台架10的带动下移动，实现道岔转辙动作。该结构的道岔转辙驱动机构100通用性好，整套机构结构可实现模块化设计，安装调试简单，零部件通用率高，可自行调整多个驱动单元110的位置，实现自由组合以适用于不同功能线型的道岔，降低了整个***整体制造、使用成本。
图1至图5示出了根据公开实施例的道岔转辙驱动机构100的示例，其中图1至图3为结构示意图，图4和图5为简化原理图。如图1至图5所示，第二移动副102的移动方向与道岔梁200的延伸方向垂直，一个为左右方向，另一个为前后方向。由此，移动台架10在第二移动副102的作用下的相对于固定导向件20的位移量即为道岔梁200在其横向(与道岔梁200的延伸方向垂直的方向)上的位移量，移动性更好，工作效率更高，节能性更好。
根据本公开的一些实施例，道岔梁200可包括多个梁段210，多个驱动单元110至少 设置在两个梁段210上。如图1至图5所示。由此，两个梁段210可以在各自的驱动单元110的带动下发生移位，并且当梁段210多于两个时，其它未设置驱动单元110的梁段210可以在相邻梁段210的带动下移位，实现预定的道岔梁转辙线型与距离，道岔梁200的整体转辙效果好，并且可以降低成本。
参照图1所示，在道岔梁200的延伸方向上从后向前，多个梁段210可包括第一梁段210Ⅰ、第二梁段210Ⅱ、第三梁段210Ⅲ和第四梁段210Ⅳ，第一梁段210Ⅰ、第二梁段210Ⅱ、第三梁段210Ⅲ和第四梁段210Ⅳ依次相连。多个驱动单元110可设在第二梁段210Ⅱ和第四梁段210Ⅳ上。由此，第二梁段210Ⅱ和第四梁段210Ⅳ分别可以在驱动单元110的驱动下发生主动移位，第一梁段210Ⅰ和第三梁段210Ⅲ可以发生从动移位，道岔梁200的整体移动效果好。
进一步地，驱动单元110可为四个，第二梁段210Ⅱ上可间隔设有两个驱动单元110，第四梁段210Ⅳ上可间隔设有两个驱动单元110。换言之，在四个驱动单元110中，其中两个驱动单元110与第二梁段210Ⅱ相连，并且沿第二梁段210Ⅱ的延伸方向间隔开，其中另两个驱动单元110与第四梁段210Ⅳ相连，并且沿第四梁段210Ⅳ的延伸方向间隔开。由此，不仅安装和维护方便，而且驱动效果好，可以使道岔梁200实现优异的道岔转辙动作。
在本公开中，两个移动副和转动副的具体结构不做特殊限制，可以有很多种，这对本领域技术人员来说是可以理解的，下面以本公开的具体实施例为例进行简要说明，本领域技术人员可以理解，以下所描述的结构并不是实现本公开的唯一结构，不能构成对本公开的限制。
根据本公开的一些具体实施例，第一移动副101为滚轮滑槽配合机构。滚轮滑槽配合机构配合性好，方便制造。如图3所示，第一移动副101包括滚轮111和滑槽112。滚轮111可设在移动台架10上，驱动单元110可通过连接支座113与道岔梁200相连，滑槽112可设在连接支座113上。由此，滚轮111可以在滑槽112内滚动，实现移动台架10相对于道岔梁200的移动，移动效果好且方便维护。
这里，连接支座113可以通过焊接等不可拆卸的方式固定在道岔梁200上，也可以用螺钉紧固件等可拆卸地方式设在道岔梁200上。当然，在本公开中，连接支座113不是必须的结构，例如，可以不设置连接支座113，而直接将第一移动副101的滑槽112直接设置在道岔梁200上。另外，本公开对滚轮111和滑槽112的设置位置不做具体限制，不限于附图中所示的结构，例如，还可以将滚轮111设置在道岔梁200上并将滑槽112设置在移动台架10上。
继续参照图1至图3所示，转动副103可集成在第一移动副101上并且通过第一移动副101的滚轮111实现转动。也就是说，第一移动副101的滚轮111可以作为转动副103 的组成部分来使用，滚轮111不仅可以在滑槽112内沿着道岔梁200的延伸方向滚动，还可以以竖直方向延伸的枢转轴线相对于道岔梁200枢转，可以实现移动台架10的移动和转动。由此，道岔转辙驱动机构100的结构更紧凑，集成度更高，不需要再设置专用转动装置，可以降低***复杂程度，提高可靠性，减少机构组件，降低成本。
根据本公开的一些具体实施例，第二移动副102可为齿轮齿条配合机构。第一移动副101可以包括齿条114齿轮115，齿条114可沿固定导向件20的延伸方向延伸。换言之，固定导向件20上可设有齿条114，齿条114可沿固定导向件20的延伸方向延伸，例如，图1至图3所示，齿条114可以沿左右方向延伸。该种机构配合性好，移动可靠性好且方便制造。
如图1所示，在道岔梁200的延伸方向上从后向前，多个驱动单元110的齿条114的延伸长度可递增，可参考图1中虚线所示。这种设计与多个驱动单元110的第二移动副102在道岔梁200的延伸方向上从后向前的位移递增更相适应，结构设计更合理，可以更好地满足线型布置需要且降低成本以及对空间的占用，安装时可以按长度进行排列后安装，安装不易出错。
类似地，在道岔梁200的延伸方向上从后向前，多个驱动单元110的滑槽112的延伸长度可递增，这种结构也能够更好地与移动台架10以及道岔梁200的移动情况相适应，结构设计更合理，并且安装时不易出错。
本公开对于驱动装置30的结构不做具体限制，只要能够实现驱动第二移动副102的要求即可，本领域技术人员可以根据实际情况灵活设计不同的结构。参照图1至图3所示，在本公开的一些实施例中，驱动装置30可包括电机31和减速器32。
减速器32的输入端可与电机31的输出轴相连，减速器32的输出端可与第二移动副102相连。当第一移动副101为包括齿条114齿轮115的机构时，减速器32的输出端可以与齿轮115相连，齿轮115在减速器32的带动下可以啮合在齿条114上转动。其中，在道岔梁200的延伸方向上从后向前，多个驱动单元110的减速器32的减速比递减。由此，可以通过减速器32的减速比实现多个第二移动副102的位移的不同，进而实现道岔梁200的道岔转辙动作。
根据本公开的一些实施例，驱动单元110还可包括减阻滚轮11，如图3所示，减阻滚轮11可设在移动台架10上并且可滚动地支撑在固定导向件20上。由此，减阻滚轮11可以承受驱动过程中产生的全部动静载荷，并可以减小驱动阻力，使道岔转辙驱动机构100活动更灵活顺畅。如图3所示，固定导向件20可以为导轨，固定导向件20可设有向内凹陷的导向槽，减阻滚轮11可以设置在导向槽内，并且支撑在导向槽的上侧壁面上，支撑效果好，减阻滚轮11不易脱离固定导向件20。
根据本公开实施例的跨座式单轨包括根据本公开实施例的道岔转辙驱动机构100。由于根据本公开实施例的道岔转辙驱动机构100具有上述有益的技术效果，因此根据本公开实施例的跨座式单轨适用性广，安装调试简单，成本较低。
根据本公开实施例的跨座式单轨的其他构成以及操作对于本领域的普通技术人员来说是可知的，在此不再详细描述。
