Description

一种用于悬浮车辆的牵引车
本申请要求于2021年11月03日提交中国专利局、申请号为202111293959.5、发明名称为“一种用于悬浮车辆的牵引车”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及轨道车辆技术领域，尤其涉及一种用于悬浮车辆的牵引车。
背景技术
轨道牵引车属于特种车辆，目前，铁路用轨道牵引车经过多年的发展，技术已经比较成熟。
中低速磁浮轨道是支承和引导列车运行的固定结构，包含F型断面的导磁结构和其上面的感应金属板。除传统轨道具有的承受和传递列车重力、导向力、牵引力和制动力的功能外，还应与车上安装的电磁铁、直线感应电机和传感器构成电磁回路，实现悬浮、导向以及牵引、制动及悬浮间隙测量的功能。中低速磁浮轨道较常规地铁及高铁轨道不同，其形状为F型，且在F型轨道上安装有直线电机牵引用的铝制感应板，常规的轨道牵引机车不能在磁浮线路上运行。其中，F型轨道是一种承受磁浮车辆悬浮力、导向力及牵引力的基础构建，由F型钢和感应板组成，感应板是车辆牵引用直线感应电机次级的组成部分，是安装在F型轨道上的非磁性导电材料。
中低速磁浮车辆在组装完成后需要将多车进行连挂，连挂过程是将需要连挂的两节车的车钩连接到一起，因车钩是刚性的，不能大范围拉长或缩短，因此，正常连挂时两节车有一节车不动，将另一节车推到这节静止车的旁边并将两车的车钩连接到一起。在连挂过程中，车辆依靠设置在悬浮架上的支撑轮行走(每个悬浮架上设置8个支撑轮，每节中低速磁浮车辆设置有5个悬浮架，悬浮架类似于轨道车辆的转向架，因此共有40个支撑轮)。由于支撑轮数量多，承重大，车辆阻力较大，无法通过人力完成连挂作业。常规通过轨旁钢丝绳拖拽的方式只能实现车辆拖拽，不能实现连挂。使用铰链能够完成车辆拖拽，但费时费力，且容易造成车辆及轨枕的损伤。
目前，国内商业运行的中低速磁浮线路已有多条，其中，某些线路的轨距 不同，因此，亟需能够适应多种轨距的通用牵引车。其中，轨距是指轨道两侧两悬浮磁极面中心的距离。
现有技术中有一种用于磁浮交通安装巡检救援用牵引车，为了提升摩擦力，其在F型轨道滑行面走行承载驱动轮的基础上，在F型轨道的下面也增加了加载驱动轮，其系统较复杂，该牵引车只能使用专用车辆将其从轨道一旁穿入，穿入后只能从轨道断面穿出，不能直接吊运，因此，其只能应用于正线磁浮列车救援、轨道维护等，不能满足库内车辆连挂的应用需求。
在库内车辆连挂时，为了能够拉动车辆，现有某些技术在轨排上设置了一个工装，该工装上安装有一个滑轮，使用钢丝绳一端连接车钩，一端连接地面绞盘，通过绞盘的转动拉动车辆，该方法只能完成车辆拉动，但因工装的存在，不能完成车辆连挂功能。连挂车辆时，目前可行的方案是使用铰链，将铰链一端连接到轨排上，另一端连接在车体上，通过铰链拉动，将两磁浮车体无限接近，完成车钩连挂，因距离等因素，使用铰链挪车需多次拆装，且费时费力。
因此，如何提供一种适用于磁浮车辆连挂以及库内车辆转运的装置，是本领域技术人员目前需要解决的技术问题。
发明内容

本发明提供了一种用于悬浮车辆的牵引车，包括车体1和连接于车体1下方的转向架10，转向架10上设置有车轮2和用于驱动车轮2转动的牵引电动机6，车体1上设置有为牵引电动机6提供电能的动力电池组11，车轮2的一侧同轴设置有用于与轨道3侧面接触的并且相对转向架10可转动的导向轮盘8，车体1的前端和/或后端设有车钩9。
本发明的工作原理如下：
当需要转运车辆时，将该牵引车吊装至悬浮轨道上，再将牵引车的车钩与待转运车辆的车钩相连，然后，牵引电动机6启动并驱动车轮2转动，此时，牵引车就通过车钩9带动待转运车辆实现移动。当需要连挂两个车辆时，将该牵引车放置于与车辆连挂端相对的另一端，利用牵引车推动待连挂车辆向另一个车辆靠近，直至两个车辆的车钩完成连挂。在此过程中，牵引车的导向轮盘8与轨道3的侧面接触，且导向轮盘8可旋转，在牵引车行走时能够跟随车轮2旋转，从而避免损伤轨道3。
需要说明的是，本发明可以将车轮2直接连接于转向架10上，也可以通过轮轴5设置于转向架10上，优选地，转向架10上设置有轮轴5，轮轴5上安装有至少两个车轮2，至少一个车轮2通过轨距调节结构沿轮轴5的轴向位置可调地连接于轮轴5。通过设置轨距调节结构可以调节车轮2在轮轴5轴向上的位置，从而改变两侧车轮2之间的距离，进而使该牵引车能够适用于在不同轨距上的悬浮轨道上行走。

优选地，转向架10上设置有至少两个平行布置的轮轴5，每个轮轴5上均设置有牵引电动机6和至少两个车轮2。通过在牵引车前后方向均设置有轮轴5以及牵引电动机6，使牵引车既能够实现向前移动，也能够实现向后移动。 该牵引车可以设计为前后两端对称的结构。
优选地，车轮2的外圆材质为柔性材质。具体的，该柔性材质可以选用橡胶、皮革、柔性树脂等，进一步优选地，车轮2的外圆材质为橡胶材质。本方案采用柔性的橡胶材质布置于车轮2外圆，一方面可以起到减震效果，另一方面可以增大牵引车行走时车轮2与轨道3之间的摩擦力，从而为车辆牵引提供更大的牵引力。
因车辆速度限制，并且在车轮2外圆设置了柔性材质，因此，本方案可以取消常规车辆车体和转向架之间的空气弹簧，故本方案的车体1与转向架10采用刚性连接，提高牵引车整体刚度。
优选地，牵引电动机6与车轮2之间布置有减速机构7。该减速机构7可以采用现有的减速齿轮箱或涡轮蜗杆减速机构等，减速机构7具体可以布置于牵引电动机6与轮轴5之间，通过设置减速机构7可以进一步增大轮边扭矩。
优选地，牵引电动机6为永磁同步电机，车体1上还设置有电机逆变器13。电机逆变器13直接将动力电池组11的直流电转换成变频变压的交流电并供给牵引电动机6。当然，本方案的牵引电动机6还可以选用异步电机或其他牵引电机等。另外，动力电池组11可以根据具体应用需求进行配置，为了增加重量，本方案选用了铅酸电池。当然，还可以选用锂电池作为动力电池组11，本文不再赘述。为了增大车轮2与轨道3的摩擦力并保持轨道3两侧车轮2的受力平衡，本方案还在车体1上设置了配重装置12，该配重装置12可以根据实际情况进行配置。
优选地，车体1和/或转向架10为金属型材焊接而成的框架结构。如图2所示，具体可以选用不锈钢型材或铝合金型材制作框架结构，不仅使结构进一步简化，而且还便于吊装和移动牵引车。
优选地，车体1的前端和/或后端设置有用于连接车钩9并且供车钩9上下滑动的车钩滑道15，车钩9与车钩滑道15之间设置有用于锁定车钩9的高度的车钩锁定结构。
优选地，车钩9用于与车钩滑道15连接的一端设有车钩连接板14，车钩滑道15包括用于卡接车钩连接板14两侧的卡槽16，车钩锁定结构包括沿车钩滑道15的延伸方向设置于卡槽16的侧壁的多个螺纹孔17以及若干与螺纹孔17贯穿配合的锁紧螺栓。当需要调整车钩9的高度时，将锁紧螺栓旋松，车钩9与车钩连接板14一同相对车钩滑道15上下滑动，当车钩9移动到目标 高度位置后，利用锁紧螺栓旋入螺纹孔17，使锁紧螺栓的末端抵接车钩连接板14，从而将车钩连接板14抵接贴紧于车钩滑道15，实现位置锁定。
进一步优选地，为了保证车钩连接板14与车钩滑道15之间的稳固连接，本方案将车钩滑道15设计为齿轨滑道结构，如图5所示，相应地，车钩连接板14朝向车钩滑道15一侧的表面也设计有相应的固定齿。
优选地，上述牵引车还包括无线通信装置以及遥控装置，无线通信装置设置于车体1或转向架10上并与牵引电动机6连接，遥控装置与无线通信装置通信连接，遥控装置用于控制牵引电动机6的启停和转速。如此设置，可以便于操作人员在远距离遥控操作控制牵引车移动，车体1上无需设置操纵台，还进一步简化了牵引车的结构。
本发明具有以下有益效果：
1)本发明提供的牵引车能够协助完成悬浮车辆的连挂以及库内车辆转运，应用范围广；
2)该牵引车结构简单、便于吊装作业；
3)该牵引车使用牵引电动机6驱动行走，便于操作，省时省力；
4)车轮2的外圆采用柔性材质，增大了车轮2与轨道3的摩擦力，同时起到了减震效果；
5)车轮2可以根据轨道3的轨距进行位置调整，实现了对不同轨距轨道的适应；
6)设计了齿轨滑道结构，降低了车钩9调节高度的难度。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
