[具体实施方式]
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。此外，下面所描述的本发明各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
如图1-4所示，本发明的一种适用于中低速磁悬浮列车的悬浮架助行器，其主要包括行走机构、升降机构和支撑机构。悬浮架作为磁悬浮列车非常重要的组成部件，既是整个列车动力组件的安装平台，又起着承受和传递载荷的作用，对整车的静态、动态性能有直接影响。当某个悬浮架需要更换或拆下维修时，由悬浮架拆装设备完成拆装，然后由悬浮架助行器推行至特定的检修区域，检修完毕后悬浮架存放在助行器上。通过本发明中的关键组件如行走机构、升降机构和支撑机构的相互配合，实现悬浮架的准确定位、安全存放，并保证助行器的行走平稳。
下面将对本发明的关键组件逐一进行更为具体的说明。
作为本发明的关键组件之一，行走机构包括支撑板1和万向脚轮2，万向脚轮2的数量可以根据实际需要进行设置，可设置一个，设于支撑板1底部中间，如图1-3所示，也可设置两个，分设在支撑板1底部两端，如图4所示，采用万向脚轮2使得整个助行器能实现多角度旋转并移动，便 于将拆装下的悬浮架移动至指定位置，方便可靠。支撑板1用于安装固定助行器的其他部件，在一个优选实施例中，支撑板1的横截面为倒T字型，其由水平放置的平板10以及竖直布置在平板10上的条形板11组成，采用上述结构的支撑板，可实现其他部件的稳定支撑。其中，万向脚轮2的具体参数为：容许负载为3920N，轮径×轮宽为Φ125×50mm，材质为铸铁轮毂+弹性塑料轮，规格为平板式万向型。
作为本发明的另一关键组件，升降机构安装在行走机构上，其包括底座3、丝杆4、涡轮5和手轮6，底座3安装在支撑板1的顶部，丝杆4竖直安装在底座3上；涡轮5穿过丝杆4，并与丝杆4螺纹连接；手轮6通过蜗杆7与涡轮5螺纹连接。其中，丝杆4的外径为Φ25mm，丝杆上螺纹的螺距为5mm。
底座3主要起支撑作用，并保证升降机构与行走机构的可靠连接，在一个优选的实施例中，如图5所示，底座3包括圆台12、圆板13和多个卡板14，圆台12安装在圆板13的上方，多个卡板14安装在圆板13的下方，并卡装在条形板11的两侧。通过多个卡板的夹持力，夹紧行走机构上的条形板11，使得升降机构与行走机构连接为一体。所述卡板优选为6个，6个卡板对称分布在条形板11的两侧，即条形板11的每侧设有三个卡板，以此保证夹持的稳定性及可靠性。所述圆台和圆板也可为其他形状，其主要起支撑固定作用。
丝杆4的一端与底座3固定，另一端与涡轮5螺纹连接，所述涡轮5、蜗杆7和手轮6构成助行器的升降机构，以此实现助行器的升降，便于在实际操作过程中的高度调节。具体的升降过程如下：首先转动手轮6，手轮6上的蜗杆7随之转动，转动的蜗杆7带动与其相连的涡轮5转动，由于丝杆4竖直布置，并与涡轮5螺纹连接，因此涡轮5转动可带动竖直布置的丝杆4上下运动，以此调节助行器的总体高度。
作为本发明的另一关键组件，支撑机构包括支撑套筒8和安装板9，支 撑套筒8套装在丝杆4顶部的外围，并且与涡轮5相连；安装板9安装在支撑套筒8的顶部，用于安装固定中低速磁悬浮列车的悬浮架。其中，安装板9的高度为140mm，厚度为220mm，采用该规格的安装板固定安装中低速磁悬浮列车的悬浮架时，在不过多浪费板料的前提下，可实现悬浮架最大程度的可靠稳定支撑。
在一个实施例中，支撑套筒8的底端设有一平板，涡轮5的顶端同样设有一平板，支撑套筒8与涡轮5之间通过这两个平板相连，以保证安装稳固性。在设于支撑套筒8上的平板上设有多个筋板，该多个筋板与支撑套筒8的侧面相连，以此保证支撑套筒8的支撑稳定性，并增强支撑强度。
在一个实施例中，安装板9通过水平板15安装在支撑套筒8的顶部，水平板15的底部设有多个筋板，以保证支撑稳定性。
本发明的悬浮架助行器用于支撑或存放磁悬浮列车的悬浮架时，单个助行器的承载力可达到800kg，其高度可调节量为30mm，具有支撑稳定可靠，集悬浮架存放、助行功能于一体，成本低。
下面将具体说明本发明的悬浮架助行器的使用与操作方式。
本发明根据磁悬浮列车的悬浮架结构的特殊性，设计了适用于磁悬浮列车的悬浮架的助行器，悬浮架助行器作为推送、存放悬浮架的专用工装，可以与悬浮架拆装设备配套使用，也可以单独使用。为防止悬浮架与车体分离后塌腰，需要用工艺连杆固定悬浮架，再用助行器支撑。
助行器与悬浮架拆装设备配套使用：悬浮架先由悬浮架拆装设备拆下并推至线路一侧，再由多个悬浮架助行器支撑悬浮架，例如，通过四个悬浮架助行器支撑悬浮架，助行器与悬浮架通过工艺孔利用螺栓连接，通过摇动手轮调节助行器的高度，使得四个助行器的高度保持一致，以此保证支撑的稳定性，通过助行器上的万向轮，将助行器推行至特定的检修区域。
助行器单独使用：悬浮架在开始检修前和检修完毕后，需要临时存放，利用本发明的助行器当作存放支撑设备使用，同样助行器与悬浮架通过工 艺孔利用螺栓连接。
本领域的技术人员容易理解，以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
