具体实施方式
为了能够更好的理解本发明技术方案，下面结合附图和具体实施例对本发明技术方案做进一步的详细说明。
如图1所示的悬挂式轨道单开车辆换线系统包括有前垛梁1和后垛梁2以及道岔梁3，由于该技术方案涉及单开车辆换线系统，因此前垛梁1设计为一条，后垛梁2设计为两条，对应的道岔梁3也设计为两条，道岔梁3与后垛梁2为对应关系，如图所示，曲线后垛梁2通过曲线道岔梁3与前垛梁1连接，直线后垛梁2通过直线道岔梁3与前垛梁1连接，通过道岔梁3的回转运动进入换线位置从而使后垛梁2和前垛梁1连通起来，引导车辆实现换线，即车辆能够从前垛梁1分别驶入后垛梁2中任意一条车道，或者从任意一条后垛梁2均能够驶入前垛梁1，由于采用两条道岔梁3分别对接两条后垛 梁2使得道岔梁3回转的角度较小，且道岔梁3与前垛梁1和后垛梁2衔接处更合理，因此该换线系统中道岔梁3提供了重要的作用，是将车辆引导进入正确线路的关键环节，该换线系统中设置有至少一对门架梁4实现对道岔梁3悬挂支撑，为了能够使道岔梁3绕固定点做回转运动，在道岔梁3和门架梁4之间设置回转装置5，回转装置5提供回转中心定位点，使道岔梁3能绕回转装置5为中心进行转动，在道岔梁3与门架梁4之间还设置有回转驱动机构6，通过回转驱动机构6提供动力驱动道岔梁3绕回转装置5转动，为了能够使道岔梁3悬挂并沿固定路线行走，在道岔梁3和门架梁4之间设置有走行机构7，由于回转装置5仅设置在其中一个道岔梁3上，因此为了使两个道岔梁3能够同步同心做回转运动，需要将两个道岔梁3连接起来，因此在两个道岔梁3之间还设置有连接装置，连接装置不仅用于道岔梁3连接实现同步运动，而且能够确保两个道岔梁3之间的位置关系始终保持不变。为了使道岔梁3完成换线操作后定位准确且防止松动，在前垛梁1和后垛梁2上均设有锁定机构8用于将道岔梁3与前垛梁1和后垛梁2对接后进行锁死定位。
下面结合附图对该换线系统中各装置和机构的结构做进一步的说明：
走行机构：
如图2所示的走行机构7，包括有走行轨道7-1和一组滚轮组件7-2，其中走行轨道7-1连接固定在门架梁4上，滚轮组件7-2则与道岔梁3连接，通过滚轮组件7-2实现道岔梁3悬挂。
如图3所示滚轮组件7-2包括有支撑座7-2-1、支撑轴7-2-2和滚轮7-2-3，支撑座7-2-1与道岔梁连接，支撑轴7-2-2设置在支撑座7-2-1上用于安装滚轮7-2-3，在滚轮7-2-3与支撑轴7-2-2之间设置第一关节轴承7-2-4，其中滚轮7-2-3与走行轨道7-1配合能够在走行轨道7-1上沿水平面滚动。由于装配误差、受热变形以及行车产生震动的影响，如果滚轮7-2-3与支撑轴7-2-2直接刚性连接会造成滚轮7-2-3与走行轨道7-1不能完全接触，例如其中一个滚轮7-2-3安装位置过低对道岔梁3已经形成了支撑，其余滚轮7-2-3则无法与走行轨道7-1接触或者完全接触，从而使该滚轮组件7-2受力过大造成支撑不稳定，同时影响行走稳定性，而在支撑轴7-2-2与滚轮7-2-3之间设置第一关节轴承7-2-4后，各滚轮7-2-3均能够自适应调整从而实现与走行轨道7-1完全接触，从而对道岔梁3提供更好的支撑，使行走更加稳定。
如图1所示道岔梁通过旋转方式行走时，各滚轮7-2-3的轴心与回转装置5的轴心相交，这样行走过程滚轮才能更好的滚动，当然这里的所指的滚轮轴心与旋转轴心相交 为理论上的，实际装配中不可能如此完美，但是主旨是要使滚轮轴心指向回转装置5的轴心，从而使滚轮能够沿着弧线行走，符合道岔梁3旋转特性尽量减少滚轮滑动摩擦。走行轨道7-1面积足够大的情况下，滚轮7-2-3如果有足够行走空间则走行轨道形状规格不需要限定，而如果采用如图2所述的走行轨道7-1，仅在滚轮7-2-3行走过的区域设置走行轨道7-1，则需要将走行轨道7-1设置成弧形，且使走行轨道7-1弧心与道岔梁3旋转中心同心。
该换线系统中由于道岔梁3远离旋转中心和靠近旋转中心的两端行走距离不同，远离旋转中心一端移动距离较大，而靠近旋转中心一端行走距离较小，因此可以将滚轮组件7-2安装在行走距离较大的一端。如以图1给出的结构来看，将滚轮组件安装在道岔梁3靠前垛梁1的一端。而行走距离较小的一端采用滑动方式行走，这样设置既能满足行走要求又能控制成本简化结构，当然道岔梁两侧也均可以采用滚轮组件7-2进行支撑实现行走。采用如图2所示的滚动配合滑动的行走机构时，由于道岔梁远离旋转中心一端行走距离较远采用滚动方式移动更加合理，因此滚轮组件7-2设置在远离道岔梁旋转中心较远的一端，而在靠近道岔梁旋转中心较近的一端的门架梁4上设置滑动导轨7-3，在该处道岔梁3上设置滑动架7-4，滑动架7-4滑动设置在滑动导轨7-3上，如图4所示滑动导轨7-3两端均设置有限位板7-3-1，防止回转驱动机构6失灵或是惯性过大出现道岔梁移动距离超出限定范围。为了稳定性，单个道岔梁3设置一对滑动架7-4，为了节省材料降低成本，将滑动导轨7-3设置成两段分别设置在门架梁4上保持与滑动架7-4数量和位置对应，同理为了稳定在单个道岔梁上同时设置四个滚轮组件7-2，在道岔梁两侧分别设置两个，同侧的两个滚轮组件7-2又设置在走行轨道7-1两侧。滑动导轨7-3与滑动架7-4接触面积足够大时，则不需要考虑滑动导轨7-3形状，而为了节省材料使滑动导轨7-3形状与滑动架7-4行走轨迹吻合，将滑动导轨7-3设置成弧形，同样的保证滑动导轨7-3弧心与道岔梁旋转中心重合，使得滑动架7-4移动过程中与滑动导轨7-3接触面积始终不变，为了减少滑动架7-4的磨损，在滑动导轨7-3与滑动架7-4接触位置设置铜板7-3-2。
回转驱动机构
如图5包括有安装在道岔梁3上的动力总成6-1，在门架梁4上安装齿条组件6-3，在动力总成6-1上安装有鼓形齿轮6-2与齿条组件6-3啮合，在动力总成6-1驱动下鼓形齿轮6-2沿齿条组件6-3行走时带动道岔梁3绕其回转装置5转动。
如图6所示齿条组件包括有一组直齿条6-3-1，这组直齿条6-3-1排列形成弧形，如 图7所示动力总成6-1包括电机和减速器，鼓形齿轮6-2安装在减速器上。如图5和图1所示，为了能够实现沿弧线行走，鼓形齿轮6-2轴线与水平面平行且指向回转装置5轴心，而直齿条6-3-1所组成的弧形的弧心与道岔梁回转中心同心。虽然采用的是直齿条6-3-1拼接排列而成的齿条组件6-3，但是由于采用的是鼓形齿轮6-2，因此在小范围内鼓形齿轮6-2和直齿条6-3-1齿牙之间能够保持啮合关系，而且在设计齿条组件6-3时直齿条数量越多，且各直齿条长度越短则排列而成的齿条组件6-3弧形越趋于规则的弧形。这里需要注意一下，按照严格意义上该齿条组件的排列形状应该是多边形一部分，但是从总体上看趋于弧形，因此此处可以认为其是弧形。这样设置后的齿条组件6-3和鼓形齿轮6-2配合时即使道岔梁3伸缩变形，鼓形齿轮6-2沿轴向移动后依然不影响鼓形齿轮6-2与各直齿条6-3-1之间的啮合关系。因此该驱动机构既能够满足回转驱动，又能够消除道岔梁变形对驱动机构运行稳定性的影响。
回转驱动机构安装时应尽量远离回转装置5进行安装，由于道岔梁3远离回转装置5的一端移动距离大，有足够安装空间，并且能尽可能减小回转驱动机构驱动时的载荷。
回转装置
如图8和图9所示该回转装置5包括上固定座5-1和下固定座5-2，上固定座5-1和下固定座5-2之间设置有第二关节轴承5-3，其中上固定座5-1和下固定座5-2分别与门架梁4和道岔梁3连接在一起，为方便第二关节轴承5-3安装，在上固定座5-1内设有内腔5-1-1，第二关节轴承5-3设置在内腔5-1-1中，第二关节轴承5-3外圈与内腔5-1-1内壁接触，以限制第二关节轴承5-3在内腔5-1-1中晃动，也可采用过盈配合将第二关节轴承5-3直接卡入内腔5-1-1中，使第二关节轴承5-3直接固定在内腔5-1-1中。下固定座5-2上设置回转轴5-4，回转轴5-4卡入第二关节轴承5-3内圈，为使第二关节轴承5-3运转平顺还需要对第二关节轴承5-3进行润滑，而为了避免润滑油泄漏，在上固定座5-1与回转轴5-4回转轴5-4之间设有密封圈5-5。
如图9所示上固定座5-1包括上固定柱5-1-2和上固定法兰5-1-3，内腔5-1-1设置在上固定柱5-1-2内，在上固定柱5-1-2端部设置有防止第二关节轴承5-3从内腔5-1-1脱落的挡圈5-7，该挡圈5-7与上固定柱5-1-2为一个整体，当第二关节轴承5-3与内腔5-1-1处于非卡紧状态装配时，挡圈5-7能够限制第二关节轴承5-3掉落，可以在内腔中设置套管，如该套管也可与图9中限位凸台5-1-4一起形成，以顶紧第二关节轴承5-3外圈，将第二关节轴承5-3夹紧在套管与挡圈5-7之间实现固定，当然还可以采用图9中给出的实施例将挡圈5-7和上固定柱5-1-2分体设置，通过螺栓固定连接在一起，而 在内腔5-1-1中设置限位凸台5-1-4，通过将挡圈5-7固定在上固定柱5-1-2上以将第二关节轴承5-3夹紧在限位凸台5-1-4之间，为避免装配误差，提高挡圈5-7夹紧效果，在挡圈5-7和第二关节轴承5-3之间设置轴承压套5-8，通过挡圈5-7顶紧轴承压套5-8对第二关节轴承5-3进行夹紧固定。该结构中密封圈5-5设置在挡圈5-7和回转轴之间。上述的密封圈5-5采用毛毡实施密封。
如图9所示的下固定座5-2包括下固定柱5-2-1和下固定法兰5-2-2，回转轴5-4设置在下固定柱5-2-1上，该回转轴5-4与下固定柱5-2-1可以作为一个整体，或者如图9所示回转轴5-4与下固定柱5-2-1分体设置，并通过法兰连接到下固定柱5-2-1上。
为使上固定柱5-1-2和下固定座5-2稳固，在上固定柱5-1-2与上固定法兰5-1-3以及下固定柱5-2-1与下固定法兰5-2-2之间均设有一组加强筋5-6。
连接装置
如图10所示的道岔梁连接结构包括有至少一对连接装置，连接装置用于将两个道岔梁进行连接，进而保持两个道岔梁之间的间距和位置关系，这对连接装置安装在靠近道岔梁两端的位置，当然该连接结构还能够根据实际需要在道岔梁3中段位置再增设连接装置。这对连接装置中至少设置有一个活动连接件10，也就是说在两个道岔梁之间的其中一端设置有一个活动连接件10，还能够在两个道岔梁的两端均设置为活动连接件10，亦或是在两个道岔梁3的一端设置活动连接件10另一端设置为固定连接件11。
如图11所示的活动连接件10包括有底座10-1、第三关节轴承10-2和连接杆10-3，其中底座10-1包括两个，且该底座10-1分别与两个道岔梁3相邻两侧壁固定连接，第三关节轴承10-2有两个，其分别设置在两个底座10-1上，在两个第三关节轴承10-2之间设置有连接杆10-3。以图11给出的具体实施例中底座10-1包括有安装板10-1-1和双耳10-1-2，安装板10-1-1上设置有一组固定孔10-1-3，通过螺栓连接或者铆接将安装板10-1-1与道岔梁固定连接，第三关节轴承10-2内圈通过销钉10-4与双耳10-1-2连接，而第三关节轴承10-2外圈则与连接杆10-3固定连接，当然图中仅给出一种参考实施例，具体结构中第三关节轴承10-2不一定采用双耳10-1-2的连接形式与底座10-1连接，而且还可以让第三关节轴承外圈与底座10-1连接，第三关节轴承10-2内圈与连接杆10-3连接，等等多种具体结构形式的变化可以根据实际需要进行设计，但总体方案始终通过第三关节轴承10-2和连接杆10-3将两个底座10-1连接在一起，这样通过该活动连接件10将两个道岔梁3连接在一起后在既能保证两个道岔梁之间的间距和位置关系，又能够通过第三关节轴承10-2释放自由度，当道岔梁3因温度或受到震动发生形变时第三关 节轴承10-2能够释放相应的应力，减小道岔梁的内应力集中，从而避免刚性连接损坏连接结构，提高道岔梁的使用寿命。如果在连接结构中仅设置一个活动连接件10，那么该活动连接件10最好设置在道岔梁3间距较大的一端，或者是道岔梁3活动距离较大的一端，一般在道岔梁3距离回转装置较远的一端设置活动连接件10。而且采用该活动连接件10时不需要考虑道岔梁的结构形状，如可用于直线道岔梁或曲线道岔梁，通过第三关节轴承10-2能够使底座10-1自适应道岔梁结构形状，而如果道岔梁弧度过大超出第三关节轴承10-2自适应范围，则需要在底座10-1上设置斜面以适应与该道岔梁的安装配合，该斜面可选择设置在与弧度较大的道岔梁一侧的底座上安装，如果两侧都是弧形道岔梁则两侧都可以选择安装斜面。
为了能够适应不同间距的道岔梁，该活动连接件10中的连接杆10-3能够实现长度调节，具体结构如图12所示，包括有螺纹套管10-3-1和一对螺纹杆10-3-2，螺纹套管10-3-1两端通过螺纹配合分别与两个螺纹杆10-3-2连接，螺纹杆10-3-2与第三关节轴承10-2固定连接，其中两个螺纹杆10-3-2上的螺纹旋向相反，在旋拧螺纹套管10-3-1时便能够使两个螺纹杆10-3-2通过伸出或者缩进螺纹套管10-3-1实现连接杆10-3的长度调整，在各螺纹杆10-3-2上还设置有锁死螺母10-3-3，长度调整好后，通过拧紧锁死螺母10-3-3使连接杆10-3长度锁定，避免震动造成长度变化改变道岔梁之间的间距和位置关系。当然图中给出的仅是一种实施例，实际可以将螺纹杆10-3-2和螺纹套管10-3-1位置互换，即中间设置螺纹杆10-3-2两端与第三关节轴承10-2连接的部件设置为螺纹套管10-3-1，同样锁死结构也不一定采用锁死螺母10-3-3，还可以采用顶丝等常规锁死结构进行锁死。
在连接结构中还存在设置有固定连接件的形式，如图13所示的固定连接件11，包括有中间桩11-1，在所述的中间桩11-1两端连接有第一连接板11-2和第二连接板11-3，第一连接板11-2和第二连接板11-3能够分别与两个道岔梁固定连接。为了适应不同结构形状的道岔梁，第一连接板11-2和第二连接板11-3可以根据道岔梁结构形状设置斜面以适应弧形道岔梁轮廓，从而方便与道岔梁连接，为了能够适应轨道间距，在中间桩11-1与第一连接板11-2和或第二连接板11-3之间设置有垫板11-4，通过增加垫板11-4或改变垫板11-4厚度，实现对固定连接件11的长度调整，从而消除装配误差，适应道岔梁之间间距。
锁定机构
如图14所示的锁定机构包括推力杆8-1、锁销8-2、导滑座8-3、锁定座8-4。其中 推力杆8-1和导滑座8-3一般安装在固定不动的轨道梁上，如该换线系统中的前垛梁和后垛梁上，锁销8-2滑动设置在导滑座8-3内并与推力杆8-1连接，锁定座8-4则设置在道岔梁3上，推力杆8-1推动锁销8-2在导滑座8-3内移动，锁定座8-4固定在道岔梁3上，当道岔梁3与前垛梁1和后垛梁2对接后通过推力杆8-1驱动锁销8-2插入锁定座8-4内实现对道岔梁3位置的锁定，推力杆8-1可采用电动推杆或液压杆，采用电动推杆作为推力杆8-1时可以通过PLC控制行程或者其自身带有限制行程的限位，因此锁销8-2插入锁定座8-4的深度能够控制，为了更方便的控制锁销8-2行程，该锁定机构中还设置有限位开关8-5，限位开关8-5用于控制推力杆8-1的行程，该实施例中将限位开关8-5设置在锁定座8-4上，当锁销8-2插入锁定座8-4固定深度后碰触限位开关8-5，从而使推力杆8-1停止继续推动。当道岔梁需要换线操作时，推力杆8-1驱动锁销8-2退出锁定座8-4，之后道岔梁3再进行回转运动进行换线。
补偿板
如图15所示在道岔梁3、前垛梁1以及后垛梁2对接一端设置补偿板9，补偿板9呈齿形，设置在道岔梁3、前垛梁1以及后垛梁2侧壁上，当道岔梁3与前垛梁1和后垛梁2对接后，补偿板9能够相互配合填充补偿位置的缺口，从而对对接位置处的缝隙进行补偿，因为如果对接的缝隙为直线缝隙，导向轮经过时震动较大，而采用带有斜线的齿形结合端面，配合的缝隙导向轮始终有支撑，能够减小震动。
该换线系统中集成上述装置和机构，在回转装置、连接装置、走行装置中均采用了关节轴承，能够实现自适应调整位置关系，补偿道岔梁因温度、震动因素造成的配合误差，提供稳定的支撑和运行条件，回转驱动机构的鼓形齿轮与齿条组件的安装位置也能够适应道岔梁的伸缩形变，提供稳定的驱动。以上各装置和机构结合从整体上提高了悬挂轨道换线系统的稳定运行。
以上所述仅为本申请示意性的具体实施方式，并非用以限定本申请的范围。任何本领域的技术人员，在不脱离本申请的构思和原则的前提下所作出的等同变化与修改，均应属于本申请保护的范围。而且需要说明的是，本申请的各组成部分并不仅限于上述整体应用，本申请的说明书中描述的各技术特征可以根据实际需要选择一项单独采用或选择多项组合起来使用，因此，本申请理所当然地涵盖了与本案发明点有关的其它组合及具体应用。
