Description

一种受流器及磁悬浮列车 技术领域
本申请涉及电力机车技术领域，具体地，涉及一种受流器及磁悬浮列车。
背景技术
中低速磁悬浮列车一般采用高架形式，车辆电能采集一般采用第三轨、第四轨受电方式，受流装置采用受流器。受流器按受电方向分为上部受流、下部受流和侧部受流方式。由于受流器需要一定的接触力才能保证可靠受流，而磁悬浮列车采用悬浮形式，悬浮控制对象为不稳定系统，减小垂向力对悬浮力的干扰，有利于悬浮控制的稳定性，因此采用侧部受流的形式。传统的侧部受流器结构复杂，使得安装和检修也不方便。
因此，如何降低侧部受流器的结构复杂程度，是本领域技术人员急需要解决的技术问题。
在背景技术中公开的上述信息仅用于加强对本申请的背景的理解，因此其可能包含没有形成为本领域普通技术人员所知晓的相关技术的信息。
发明内容
本申请实施例中提供了一种受流器及磁悬浮列车，以解决侧部的受流器的结构复杂的技术问题。
本申请实施例提供了一种受流器，包括：
相对而置的安装座和滑靴组件；
内连杆和外连杆，所述内连杆和所述外连杆各自有一端与所述安装座通过转轴和轴孔转动连接，各自的另一端与所述滑靴组件通过转轴和轴孔转动连接，且所述内连杆位于所述安装座和所述外连杆之间；其中，所述外连杆与所述安装座转动连接的转轴为第一外转轴，所述内连杆与所述滑靴组件转动连接的转 轴为第二内转轴；
拉伸件，所述拉伸件的两端分别固定于所述第一外转轴和所述第二内转轴，
所述拉伸件用于向所述第二内转轴施加拉伸力的作用使得所述滑靴组件与所述安装座保持距离，以保持所述滑靴组件处于远极限位。
本申请实施例还提供了以下技术方案：
一种磁悬浮列车，包括：
连接成一列的多辆车辆；
每一辆车辆对称安装有至少一对上述的受流器。
本申请实施例由于采用以上技术方案，具有以下技术效果：
所述拉伸件向所述第二内转轴施加拉伸力的作用使得所述滑靴组件与所述安装座保持距离，以保持所述滑靴组件处于远极限位。本申请实施例的受流器，拉伸件能够为所述滑靴组件提供拉伸力使得滑靴组件和安装座保持距离，以实现滑靴组件处于远极限位；受流器在动态取流时，即滑靴组件处于工作位(工作位在图2中用B表示)时，滑靴组件和所述安装座之间的距离小于所述滑靴组件处于远极限位时所述滑靴组件和安装座之间的距离；且滑靴组件和电轨之间的接触力需要达到预定值，这个接触力是通过拉伸件来实现的。因此，本申请实施例的受流器，不但能实现保持滑靴组件处于远极限位，而且能在滑靴组件处于工作位时提供滑靴组件和电轨之间的接触力，同时，结构简单，便于生产制造，以及安装和维修。

具体实施方式
为了使本申请实施例中的技术方案及优点更加清楚明白，以下结合附图对本申请的示例性实施例进行进一步详细的说明，显然，所描述的实施例仅是本申请的一部分实施例，而不是所有实施例的穷举。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
实施例一
图1为本申请实施例受流器的立体示意图；图2为图1所示受流器的侧视图；图3为图1所示受流器的主视图；图4为图3所示受流器的A-A剖视图。如图1，图2，图3和图4所示，本申请实施例的受流器100，包括：
相对而置的安装座110和滑靴组件120；
内连杆131和外连杆132，所述内连杆131和所述外连杆132各自有一端与所述安装座110通过转轴和轴孔转动连接，各自的另一端与所述滑靴组件120通过转轴和轴孔转动连接，且所述内连杆131位于所述安装座和所述外连杆132之间；其中，所述外连杆与所述安装座转动连接的转轴为第一外转轴143，所述内连杆与所述滑靴组件转动连接的转轴为第二内转轴142；
拉伸件150，所述拉伸件的两端分别固定于所述第一外转轴143和所述第二内转轴142，所述拉伸件150用于向所述第二内转轴142施加拉伸力的作用使得所述滑靴组件与所述安装座保持距离，以保持所述滑靴组件120处于远极 限位，图2中用A位置表示。
本申请实施例的受流器包括安装座，滑靴组件，内连杆，外连杆和拉伸件；其中，安装座和滑靴组件相对而置，所述内连杆和所述外连杆各自有一端与所述安装座通过转轴和轴孔转动连接，各自的另一端与所述滑靴组件通过转轴和轴孔转动连接，且所述内连杆位于所述安装座和所述外连杆之间；所述外连杆与所述安装座转动连接的转轴为第一外转轴，所述内连杆与所述滑靴组件转动连接的转轴为第二内转轴，所述拉伸件的两端分别固定于所述第一外转轴和所述第二内转轴，这样，所述拉伸件向所述第二内转轴施加拉伸力的作用使得所述滑靴组件与所述安装座保持距离，以保持所述滑靴组件处于远极限位。本申请实施例的受流器，拉伸件能够为所述滑靴组件提供拉伸力使得滑靴组件和安装座保持距离，以实现滑靴组件处于远极限位；受流器在动态取流时，即滑靴组件处于工作位(工作位在图2中用B表示)时，滑靴组件和所述安装座之间的距离小于所述滑靴组件处于远极限位时所述滑靴组件和安装座之间的距离；且滑靴组件和电轨之间的接触力需要达到预定值，这个接触力是通过拉伸件来实现的。因此，本申请实施例的受流器，不但能实现保持滑靴组件处于远极限位，而且能在滑靴组件处于工作位时提供滑靴组件和电轨之间的接触力，同时，结构简单，便于生产制造，以及安装和维修。
本申请实施例的受流器为适应电轨的高度偏差，满足耐冲击要求，受流器滑靴组件的工作范围设定在图2所示的A以内。滑靴组件和电轨之间的接触力是靠拉伸件提供，在B位置时滑靴组件处于工作位时，滑靴组件和电轨之间的接触力为130N，保证了浸金属碳滑块机械磨损和电气磨损总和达到最小。
关于安装座的结构，实施中，可以采用如图1，图2，图3和图4所示的结构。如图1，图2，图3和图4所示，所述安装座包括安装座本体和凸设于其上的连杆基座111；其中，所述内连杆131和所述外连杆132转动连接于所述连杆基座111，所述内连杆与所述连杆基座转动连接的转轴是第一内转轴141，所述外连杆与所述滑靴组件转动连接的转轴是第二外转轴144；
所述第一内转轴141位于所述安装座本体和所述第一外转轴143之间，且位于所述第一外转轴143和所述第二外转轴144之间。
这样结构和安装的内连杆和外连杆，内连杆和外连杆向安装座本体转动的程度较大，进而使得滑靴组件可以向安装座本体转动的程度也较大，即滑靴组件靠近安装座本体的程度可以更多。
实施中，如图4所示，所述第二内转轴，所述第一外转轴和所述第二外转轴分别通过球轴承与轴孔连接。这样，转动连接的转动更加灵活。
关于滑靴组件的结构，实施中，图5为图1所示受流器的滑靴组件中的滑靴和滑靴安装板固定且未与滑靴基座连接的示意图，可以采用如图1，图3，图4和图5所示的结构。如图4和图5所示，所述滑靴组件包括滑靴121-1和与之连接的滑靴基座122，所述内连杆131和所述外连杆132转动连接于所述滑靴基座122；
所述内连杆131和所述外连杆132相互平行，所述第一内转轴141和所述第一外转轴143之间的连线与所述第二142内转轴和所述第二外转轴144之间的连线平行。
这样，内连杆，所述外连杆，第一内转轴和所述第一外转轴之间的连线，所述第二内转轴和所述第二外转轴之间的连线组成了平行四边形机构，结构简单，同时又能较大程度的带动滑靴向安装座本体转动。
关于拉伸件的具体结构，可以采用如图1，图3和图4中所示的结构，所述拉伸件150是拉伸弹簧且所述拉伸弹簧处于拉伸状态。
拉伸弹簧结构简单，能够提供足够的拉伸力。
为了使得本申请实施例的受流器实现气动驱动，如图4所示，还包括：
气缸160，固定于所述安装座本体，且所述气缸160与所述内连杆131位于所述连杆基座111的同一侧；
拨块170，固定于所述第一内转轴141，且所述拨块170与所述气缸的活塞杆160-1连接；
其中，所述拨块170用于在所述气缸的活塞杆的作用下，带动所述滑靴组件120从所述远极限位向靠近所述安装座的方向摆动以完成脱靴。
这样结构的气缸和拨块，在图4中，所述气缸的活塞杆向左移动，推动拨块顺时针转动，内连杆和外连杆带动所述滑靴组件从所述远极限位向靠近所述安装座的方向摆动以完成脱靴，即本申请实施例的受流器的脱靴是通过气缸实现的，受流器是气动式受流器，与需要手柄和人员手动方式完成脱靴相比，更加便捷，同时也更加安全。
为了使得本申请实施例的受流器在滑靴组件保持脱靴状态时，减少能量包括气量的消耗，实施中，如图4所示，本申请实施例的受流器还包括：
锁闭杆181，固定于所述滑靴基座122；
挂钩182和弹性复位件183，所述挂钩182通过所述弹性复位件设置于所述安装座本体，且所述挂钩182与所述锁闭杆181相对设置；其中，所述挂钩在不受外力作用时保持初始位置，所述初始位置是所述挂钩的开口朝向所述气缸的位置；
所述锁闭杆181用于在所述滑靴组件向靠近所述安装座摆动时，推动所述挂钩182从所述初始位置向远离所述气缸的方向(在图4中的顺时针方向)转动，直至所述锁闭杆181滑进所述挂钩182内，即滑靴组件进入近极限位，在图2中用C位置表示；即完成脱靴；
所述挂钩182用于在所述锁闭杆181滑进所述挂钩内后复位至所述初始位置，以勾住所述锁闭杆182保持所述滑靴组件处于近极限位。
这样，受流器完成脱靴时，所述滑靴组件从所述远极限位向靠近所述安装座的方向摆动是拨块在气缸的活塞杆的作用下实现的，即气缸需要压入压力气体实现；而滑靴组件保持滑靴组件处于近极限位是通过锁闭杆和挂钩的配合实现的，此时气缸不再需要压入压力气体，节约了能源，减少了消耗。
实施中，如图4所示，所述弹性复位件183可以是扭力弹簧。
关于气缸的结构，实施中，如图4所示，所述气缸160是双作用气缸；
所述双作用气缸的两个活塞杆中，靠近所述拨块的活塞杆与所述拨块170连接。
这样，拨块和与之连接的活塞杆，可以实现带动所述滑靴组件从所述远极限位向靠近所述安装座的方向摆动以完成脱靴。
如前所述，滑靴组件保持滑靴组件处于近极限位是通过锁闭杆和挂钩的配合实现的，那么就存在在需要起复滑靴组件时如何实现起复的问题。实施中，如图4所示，所述挂钩182包括挂钩本体和与之固定的拨把182-1；
所述拨把182-1用于在所述锁闭杆181滑进所述挂钩内所述挂钩复位至所述初始位置后，在靠近所述挂钩的活塞杆的推动作用下，带动所述挂钩从所述初始位置向远离所述气缸的方向转动，直至所述锁闭杆从所述挂钩内滑出所述挂钩复位至所述初始位置，以使所述滑靴组件复位至所述远极限位。
这样，拨把和双作用气缸的靠近所述挂钩的活塞杆相互配合，可以实现带动所述滑靴组件从所述近极限位复位至所述远极限位，实现复滑靴组件的起复。即本申请实施例的受流器的起复也是通过气缸实现的，与需要手柄和人员手动方式实现起复相比，更加便捷，同时也更加安全。
为了通过双作用气缸完成脱靴和起复，如图4所示，所述双作用气缸的缸体中靠近所述拨块的一侧设置有起复进气口161，所述双作用气缸的缸体中靠近所述挂钩的一侧设置有脱靴进气口162。
脱靴时，从脱靴进气口压入压力气体左侧活塞杆向左移动，左侧活塞杆推动拨块连同第一内转轴顺时针转动，第一内转轴带动内连杆和外连杆顺时针摆动，滑靴组件靠近所述安装座，锁闭杆推动挂钩顺时针转动直至滑至挂钩内；挂钩在扭力弹簧的作用下逆时针转动直至复位至初始位置，此时，挂钩锁住了锁闭杆，进而锁住了滑靴组件，滑靴组件处于近极限位。起复时，从起复进气口压入压力气体右侧活塞杆向右移动，克服扭力弹簧的作用力推动拨把连同挂钩顺时针转动，滑靴组件在拉伸弹簧的拉伸作用力下，锁闭杆从挂钩中脱离且内连杆和外连杆逆时针摆动，带动滑靴组件逆时针转动至复位至远极限位。
脱靴进气口可以通过设置脱靴电磁阀控制脱靴进气口的通断，起复进气口可以通过设置起复电磁阀控制起复进气口的通断，而脱靴电磁阀和起复电磁阀可以通过控制电路控制。因此，脱靴进气口和起复进气口的存在，为电动控制气动式受流器准备了条件。
实施中，图6为图1所示受流器的局部立体图，如图1，图3和图6所示，所述内连杆131是两个，两个所述内连杆通过同一所述第一内转轴141与所述安装座转动连接，两个所述内连杆141通过同一所述第二内转轴与所述滑靴组件连接；所述两个内连杆141相对于所述气缸对称设置；
所述外连杆132是两个，两个所述外连杆132通过同一所述第一外转轴143与所述安装座转动连接，两个所述外连杆132通过同一所述第二外转轴144与所述滑靴组件连接；所述两个外连杆132相对于所述气缸对称设置。
相对于所述气缸对称设置的两个内连杆和两个外连杆，再配合连杆基座和滑靴基座，形成受力对称且结构稳固的结构，提高了受流器的横向刚度，减小了受流靴因为横向刚度不足引起的偏磨程度，使得受流器更加结实耐用。
由于受流器在其所安装的磁悬浮列车高速(如100km/h)运行时承受来自电轨较大的随机振动，受流器需要缓解振动和冲击。实施中，滑靴和滑靴基座之间的连接结构，如图5所示，所述滑靴基座朝向所述滑靴安装板的一侧固定有板弹簧191；具体的，所述板弹簧191通过螺栓固定在所述滑靴基座朝向所述滑靴组件的一侧；
如图4和图5所示，所述滑靴组件还包括与所述滑靴121-1固定的滑靴安装板121-2，滑靴安装板121-2上设置有凸起的安装部121-3；安装部与所述滑靴基座通过活动螺栓121-4实现螺栓连接且所述活动螺栓的螺栓连接具有一定活动间隙，使得保持所述板弹簧191处于被压缩状态且所述板弹簧191被压缩的程度能调整。进一步的，活动螺栓的螺栓连接使固定在一起的滑靴和滑靴安装板能轻微转动，即滑靴能够根据轨道的平面角度调整接触角度，让滑靴组件更好的适应电轨。
实施中，还包括橡胶轴承，所述橡胶轴承具有方形内圈和圆形外圈；
所述第一内转轴与所述拨块固定的一端具有凸出的方形部，所述拨块具有方形凹槽；
如图4所示，所述橡胶轴承的方形内圈和所述第一内转轴的方形部套接固定，所述拨块的方形凹槽和所述第一内转轴的方形部的端部固定。
由于板弹簧处于被压缩状态，能够对滑靴和滑靴安装板施加远离滑靴基座的力的作用，使得板弹簧能吸收轨道的一次冲击振动；同时，橡胶轴承能吸收轨道不平顺带来的二次冲击振动。
实施中，受流器的滑靴组件设置为弱连接结构，可在受流器受到巨大的冲击时优先断开弱连接，保护受流器固定的悬浮架不被破坏。
图7为与图1所示受流器为镜像结构的受流器的主视图。本申请实施例的受流器，包括如图1至图6所示的第三轨受流器与之镜像如图7所示的第四轨受流器。如图1和图3所示，第三轨受流器还包括熔断器盒192。如图7所示，第四轨受流器在第三轨受流器中熔断器盒的位置用过渡铜板代替，其他结构是对称分布。

连接成一列的多辆车辆；
每一辆车辆对称安装有至少一对实施例一所述的受流器100。
其中一个具体的实施例，以磁悬浮列车是全动车磁浮车辆为例，车辆分为有司机室的动车(MC车)和无司机室的动车(M车)两种型式，采用6辆编组全动车，其中每3辆组成一个动力单元；每个动力单元的中间一辆车辆设置 4台受流器，其余两辆车辆各设置2台受流器。
需要说明的是，上述具体的实施例，仅仅是列举了一种磁悬浮列车的编组形式和受流器安装的方式，可以根据磁悬浮列车的要求进行编组和受流器的安装。
为了实现实施例一的受流器的安装，还包括与所述受流器对数一致的安装架，所述安装架包括下架220和上架210。
图13为安装本申请实施例受流器的安装架的下架的立体示意图；图14为图13所示下架的侧视图；图15为图13所示下架的另一角度的侧视图；图16为图13所示下架的再一角度的侧视图。如图11，图12，图13，图14，图15和图16所示，所述下架220包括下架顶板221和固定于所述下架顶板之下的下架侧板222，所述下架侧板222用于固定所述受流器。

上架底板211，固定于所述下架顶板221之上；
固定于所述上架底板之上的第一上架立板212-1和第二上架立板212-2，其中，所述第一上架立板212-1设置有侧部螺栓孔231；
固定于所述第二上架立板之上且具有顶部螺栓孔232的上架顶板213，其中，所述顶部螺栓孔232，所述侧部螺栓孔231与所述磁悬浮列车的悬浮架的螺栓孔以及螺栓相配合以将所述安装架固定于所述悬浮架。
其中，所述下架220与所述上架底板211之间的固定通过螺孔和螺栓实现。
受流器通过上架、下架组成的安装架可靠安装在悬浮架上，安装方式可靠，为受流器提供了足够的安装强度，同时检修和拆装方便。如图13所示，顶部螺栓孔232是两个，侧部螺栓孔231是三个，顶部螺栓孔和侧部螺栓孔的数量以及位置都是与既有的悬浮架相配合的，对悬浮架不进行改造。
进一步的，如图13和图15所示，所述下架220还包括：
两个下架筋板223，相对固定在所述下架顶板221和所述下架侧板222之间；
具有受流器安装孔的安装板224，焊接固定在所述下架筋板223远离所述下架侧板一端。
安装板是焊接固定于所述下架筋板一端，由于焊接的精度较差，为了补偿该安装方式带来的弊端，如图1和图2所示，所述受流器还包括：
具有安装圆孔的固定齿板193，所述固定齿板与所述安装座固定；
具有调整长孔的调整齿板194；其中，所述安装圆孔，所述调整长孔和所述受流器安装孔以及螺栓配合以使所述调整齿板固定在所述固定齿板和所述安装板之间，所述调整齿板和所述固定齿板的齿之间咬合且所述固定齿板能以齿间间距为单位纵向调整所述受流器。
这样，在受流器的滑靴与电轨(第三轨或第四轨)在上下方向错开时，通过向上或向下调整固定齿板可以以齿间间距为单位纵向调整受流器，避免造成受流器与电轨偏磨。
进一步的，如图17，图18，图19，图20和图21所示，上架还包括两个上架筋板214，一个所述上架筋板固定于所述上架底板211和所述第一上架立板212-1之间，一个所述上架筋板固定于所述上架底板211和所述第二上架立板212-2之间。
这样，上架筋板起到了加固的作用，使得上架更加结实。
如图10所示，每一对所述受流器100包括第三轨受流器和第四轨受流器，且所述第三轨受流器和所述第四轨受流器是镜像结构；
每一对所述安装架包括第三轨受流器安装架和第四轨受流器安装架，且所述第三轨受流器安装架和第四轨受流器安装架是镜像结构；

如图10所示，第三轨受流器和第四轨受流器分别安装在轨道水泥梁330两侧，第三轨受流器与第三轨340配合接触受流，第四轨受流器与第四轨350配合接触受流，分别用于对称设置在磁悬浮列车的每一车辆的两侧，负责为车辆供电；其中，第三轨为受电轨，可接如DC1500V的正电；第四轨为回流轨。
图22为本申请实施例磁悬浮列车的受流器控制电路的示意图。本申请实施例的磁悬浮列车的受流器控制电路，如图22所示，受流器控制采用司机室开关集控方案，通过设置在司机台的开关可以同时控制整列车的受流器的动作，通过设置在司机台的脱靴指示灯反馈各个车的指令执行情况。同时，通过在列车线上设置司机占用继电器触点，能防止非占用端的司机室误操作，提高了控制的安全性。
具体的控制逻辑为：
如图22所示，控制电路采用DC110V电源，电源处设置空气断路器(F01)，通过司机占用继电器触点到司机台设置受流器控制开关(S01，三位置自复位扳键开关)，标识为“起复”、“0”、“脱靴”，集中控制整列车的受流器；设置绿色指示灯(L01)，脱靴指令发出后延时8s，指示灯点亮，起复指令发出后延时8s，指示灯熄灭。
1)脱靴
将脱靴开关(S01)打到“脱靴”位，“脱靴列车线”、“0位列车线”、“起复列车线”均得电，脱靴继电器(K02)得电，延时继电器(K03)控制端口得电，驱动脱靴电磁阀(V02)得电控制本车受流器脱靴。脱靴开关(S01)自动回“0”位，“脱靴列车线”、“起复列车线”失电，“0位列车线”保持得电状态，脱靴继电器(K02)状态保持得电，延时继电器(K03)控制端口断电，触点延时8s断开，脱靴电磁阀失电，指示灯(L01)亮；其中，脱靴电磁阀用于控制脱靴进气口的通断；
2)起复
将脱靴开关(S01)打到“起复”位，“起复列车线”得电，其余列车线失电，脱靴继电器(K02)不得电，延时继电器(K03)控制端口得电，驱动起复电磁阀(V01)得电控制本车受流器起复。脱靴开关(S01)自动回“0”位，延时继电器(K03)控制端口断电，触点延时8s断开，起复电磁阀失电，指示灯(L01)熄灭；其中，起复电磁阀用于控制起复进气口的通断；。
指示灯(L01)的点亮和熄灭分别延迟于脱靴电磁阀(V02)和起复电磁阀(V01)8s，因为通过受流器试验得到，在8秒内能确保完成脱靴和起复动作，由于指示灯仅反馈指令的执行情况(即各车的继电器状态)，而不反馈实际的受流器状态，因此设置的延迟时间为8秒。该反馈回路采用“从非占用端取电，在占用端反馈”的逻辑。
控制电路采用集控方案，同时有执行反馈信号，能够从执行层面排查故障，增强了可操作性和可维护性，为该受流器在磁浮上的应用提供了可行的控制方案。
电动控制气动式的受流器，与既有的机械手动式侧部受流器下相比，解决了机械式侧部受流器日检工作量大、操作风险较高、高架操作难度大的技术问题，同时，可以完成受流器在紧急的情况下脱靴任务。
尽管已描述了本申请一些可选的实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括一些可选的实施例以及落入本申请范围的所有变更和修改。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
