除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。

“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
放射治疗是利用放射线治疗肿瘤的一种局部治疗方法，是治疗恶性肿瘤的一项重要手段，而放疗设备是开展放射治疗的关键医疗设备。
在相关技术中，放疗设备包括底座110和滚筒200，滚筒200可转动的设置于底座110上，滚筒200上设置有治疗头，该治疗头可随着滚筒200的转动而转动。
相关技术中提供的放疗设备，其底座110上沿滚筒200的轴向的两端均设置有摩擦轮，通过滚筒200两侧的摩擦轮对滚筒200形成支撑，并且由驱动机构300驱动滚筒200两端的摩擦轮转动，以驱动滚筒200转动，由于驱动机构300需要同时驱动滚筒200两侧的摩擦轮转动，因此，相关技术中的驱动机构300一般设置于滚筒200沿轴向的中间位置，然后驱动机构300与两侧的摩擦轮之间通过较长的驱动轴连接，从而由驱动机构300同时驱动两侧的摩擦轮转动，并带动滚筒200转动。
但是，由于驱动机构300设置于中间位置，因此，滚筒200转动时，滚筒200上的其他部件有可能与驱动机构300发生碰撞，整体结构不合理。
另外，驱动机构300与摩擦轮之间通过较长的驱动轴连接，会影响传动效率，并且摩擦轮传动的定位误差较大，支撑时会引起沿滚筒200轴向的窜动，影响滚筒200的转动精度。
为解决上述问题，如图1、图2所示，本公开提供一种机架组件，包括机架100、滚筒200以及驱动机构300，滚筒200转动设置于机架100上，滚筒200沿其轴向的前端和后端均与机架100转动连接，驱动机构300与滚筒200的前端或者后端传动连接。
本公开提供的机架组件，驱动机构300与滚筒200的前端或者后端传动连接，即驱动机构300仅与滚筒200的一端传动连接，因此，驱动机构300可以设置于靠近滚筒200前端或者后端的区域，从而能够避免滚筒200转动时，其他部件与驱动机构300发生碰撞。并且由于驱动机构300设置于靠近 滚筒200的前端或者后端的区域，因此，驱动机构300与滚筒200之间不需要通过驱动轴连接，有利于提高传动效率。
如图1、图2所示，本公开提供的驱动机构300包括驱动单元以及传动副，驱动单元与滚筒200之间通过传动副传动连接。由驱动单元驱动传动副运动，以带动滚筒200转动，从而通过驱动单元的开启与停止，能够控制滚筒200的转动角度。
在一些实施例中，传动副可以采用以下结构，如图1、图2所示，其包括传动齿轮320和齿圈230，驱动单元的输出轴与传动齿轮320传动连接，传动齿轮320与齿圈230啮合，齿圈230固定于滚筒200上。传动副采用传动齿轮320和齿圈230，齿轮传动具有传动准确、效率高、结构紧凑、工作可靠、使用寿命较长等优点。
具体地，齿圈230可以固定于滚筒200的端面上并且与滚筒200同轴设置，也可以将齿圈230套设于滚筒200上，由于齿圈230与滚筒200固定连接，因此，驱动机构300驱动齿圈230转动时，即可带动滚筒200一同转动。
并且，齿圈230与滚筒200之间可以直接通过焊接、螺栓等方式固定连接，也可以将齿圈230通过其他部件与滚筒200相对固定，因此，对于齿圈230与滚筒200之间的固定方式不做限定。
在一些实施例中，传动副还可以采用以下结构，其包括第一传动带以及传动轮，传动轮固定于滚筒200上，驱动单元的输出轴与传动轮通过第一传动带传动连接。即第一传动带分别绕过驱动单元的输出轴和传动轮，当驱动单元的驱动轴转动时，通过摩擦力带动第一传动带运动，再由第一传动带通过摩擦力带动传动轮转动，从而由传动轮带动滚筒200转动，传动副采用传动带和传动轮，带传动具有传动平稳、结构简单、成本低、维护方便等优点。
本公开提供的驱动单元可以采用电机310，也可以采用其他能够输出扭矩的元件，在此不做具体限定。
另外，在下文中实施例中均以电机310作为驱动单元进行说明，并且传动副以传动齿轮320和齿圈230为例进行说明。
为降低滚筒200转动的速度，如图1、图2所示，本公开提供的电机310和传动齿轮320之间还设置有减速机构400，电机310的输出轴与减速机构400的输入轴连接，减速机构400的输出轴与传动齿轮320连接。通过减速机构400能够降低电机310的输出轴输出的转速，以使 滚筒200的转动速度降低，从而更加精确控制滚筒200的转动角度。
在一些实施例中，减速机构400可以为多组传动比不同的齿轮副，也可以采用减速机，即能够降低电机310的转速的部件均能够作为减速机构400使用。
在一些实施例中，本公开提供的减速机构400可以为以下结构，如图2、图3所示，包括第一减速机410，电机310的输出轴与第一减速机410的输入轴连接，第一减速机410的输出轴与传动齿轮320连接。通过在电机310与传动齿轮320之间设置第一减速机410，以降低电机310输出轴的转速，使传动齿轮320的转速较小，再由传动齿轮320带动齿圈230转动，以使滚筒200转动，由于第一减速机410的输出轴的转速较低，因此，使齿圈230的转速降低，从而使滚筒200的转速降低，便于精确控制滚筒200的转动角度。
在一些实施例中，本公开提供的减速机构400还可以为以下结构，如图2、图4所示，包括第二减速机420和第三减速机430，电机310的输出轴与第二减速机420的输入轴连接，第二减速机420的输出轴通过传动组件440与第三减速机430的输入轴传动连接，第三减速机430的输出轴与传动齿轮320连接。在电机310和传动齿轮320之间设置有两个减速机，即电机310输出的转速经过两次减速后，再传递至传动齿轮320，从而进一步降低传动齿轮320的转速，再由传动齿轮320带动齿圈230转动，以使滚筒200转动，即降低了滚筒200的转速，有利于进一步提高滚筒200转动角度的控制精度。
具体地，本公开提供的第一减速机410、第二减速机420和第三减速机430可以为齿轮减速器、蜗杆减速器以及行星齿轮减速器，也可以为单级减速器或者多级减速器，因此，对于本公开提供的减速器的具体种类不做限定。
另外，本公开提供的第一减速机410、第二减速机420和第三减速机430可以采用相同种类的减速器，也可以采用不同种类的减速器。
在一些实施例中，本公开提供的传动组件440可以为以下结构，如图4所示，其包括与第二减速机420的输出轴连接的第一带轮441，以及与第三减速机430的输入轴连接的第二带轮442，第一带轮441与第二带轮442之间通过第二传动带443传动连接。第二减速机420与第三减速机430之间采用带传动的方式传递扭矩，带传动具有传动平稳、结构简单、成本低、维护方便等优点。
在一些实施例中，本公开提供的传动组件440还可以为以下结构，其包括与第二减速机420的输出轴连接的第一链轮，以及与第三减速机430的输入轴连接的第二链轮，第一链轮与第二链轮之间通过链条传动连接。第二减速机420与第三减速机430之间采用链传动的方式传递扭矩，链传动具有无弹性滑动和打滑现象、平均传动比准确、工作可靠、效率高、传动功率大等优点。
在一些实施例中，如图2、图4所示，在电机310的输出轴上设置有制动器330。通过制动器330能够及时使电机310的输出轴停止转动，例如，当机架组件紧急制动时，电机310失去使能，停止扭矩输出，但是，滚筒200在惯性作用下有继续转动的趋势，此时，制动器330在电机310的输出轴上施加方向扭矩，从而使减速器不能继续转动，即传动齿轮320不能继续转动，进而使滚筒200停止转动。
相关技术提供的放疗设备，由于底座110与滚筒200之间为分体结构，在运输时，需要分别进行运输，并且到医院后，需要先将底座110固定于地面上，然后通过吊装设备将滚筒200吊装至底座110上，在吊装的同时还需要确保滚筒200与底座110上的摩擦轮精确配合，由于放疗设备一般安装于室内，空间比较狭小，通过吊装设备进行吊装，施工较为不便，从而导致安装难度升高，交付周期较长，并且降低了用户体验。
为解决上述问题，如图5、图6所示，本公开实施例提供的机架组件中，上述机架100包括底座110和支撑框120，支撑框120固定于底座110的一侧，支撑框120上开设有固定孔121，底座110的另一侧设置有滚动支撑部130，滚筒200沿其轴向的一端可转动的设置于固定孔121内，滚筒200另一端与滚动支撑部130抵接，上述齿圈230固定于滚筒200上靠近支撑框120的一端。
本公开提供的机架组件，由于在底座110上设置有支撑框120，支撑框120上开设有固定孔121，滚筒200沿其轴向的一端转动设置于固定孔121内，另一端与底座110上的滚动支撑部130抵接，从而实现滚筒200相对于底座110转动，并且由于滚筒200的一端设置于支撑框120的固定孔121内，即固定孔121能够对滚筒200形成限位，使滚筒200与底座110不能相互分离，从而在运输时，能够将滚筒200与底座110以及支撑框120一起运输，即提前将滚筒200与机架100组装在一起，然后一同运输至医院进行安装。相比于相关技术，本公开提供的机架组 件可以提前组装好，从而将滚筒200和机架100一同运输，有利于降低运输成本，并且将机架组件整体运输至医院后，只需整体固定于地面上即可，不需要在狭小的空间内进行组装，从而能够降低施工难度，缩短交付周期，有利于提高用户体验。
在一些实施例中，本公开提供的支撑框120和底座110之间可以通过焊接等方式进行固定连接，也可以通过螺栓等零件进行固定连接，还可以设置为一体成型的结构，因此，对于二者之间的固定方式不做具体限定。
需要指出的是，滚动支撑部130设置于底座110上，是指滚动支撑部130相对于底座不动，但滚动支撑部130与滚筒200之间能够相对滚动，也就是说滚动支撑部130包括转动部分和固定部分，转动部分能够相对于固定部分转动，因此，固定部分与底座110固定连接，转动部分与滚筒200抵接，从而当滚筒200转动时，转动部分同时转动，从而能够减小滚筒200转动时的摩擦力。
另外，齿圈230设置于滚筒200上靠近支撑框120的一端，因此，驱动机构300可以设置于底座110上靠近支撑框120的一侧，也可以设置于支撑框120上，或者其他靠近齿圈230的位置，在此对于驱动机构300的具体位置不做限定。
如图7、图8所示，本公开提供的机架组件还包括转盘轴承140，滚筒200通过转盘轴承140转动设置于固定孔121内。通过转盘轴承140能够实现滚筒200与支撑框120之间的转动连接，由于转盘轴承140是一种能够同时承受较大的轴向负荷、径向负荷和倾覆力矩等综合载荷，集支撑、旋转、传动、固定等多种功能于一体的特殊结构的大型轴承，因此，使用转盘轴承140能够支撑整体体积和重量较大的滚筒200，从而实现滚筒200在固定孔121内转动。
具体地，如图7、图8所示，转盘轴承140的外圈142与支撑框120固定连接，转盘轴承140的内圈141与滚筒200固定连接。通过将转盘轴承140的外圈142固定于支撑框120上，转盘轴承140的内圈141与滚筒200固定连接，从而使滚筒200能够相对于支撑框120转动，并且通过转盘轴承140能够使支撑框120与滚筒200形成一体式结构，不能分离，便于整体运输和安装。
在一些实施例中，转盘轴承140的外圈142与支撑框120之间可以采用紧固件143进行连接，同时，转盘轴承140的内圈与滚筒200之间 可以采用焊接方式进行连接。
在一些实施例中，转盘轴承140的外圈142与支撑框120之间可以采用焊接方式进行连接，同时，转盘轴承140的内圈与滚筒200之间可以采用紧固件143进行连接。
在一些实施例中，转盘轴承140的外圈142与支撑框120之间，以及转盘轴承140的内圈与滚筒200之间均采用紧固件143进行连接。
相比于焊接固定，通过紧固件143固定，更加便于拆卸，有利于维修更换零件。
在一些实施例中，如图7、图8所示，该紧固件143可以采用螺栓，通过在转盘轴承140的外圈142和支撑框120上沿平行于固定孔121的轴线的方向开设螺纹孔，并且绕固定孔121的周向开设多个螺纹孔，然后通过多个螺栓一一对应与转盘轴承140的外圈142上的螺纹孔以及对应的支撑框120上的螺纹孔配合，从而实现转盘轴承140的外圈142与支撑框120固定连接。
在一些实施例中，如图7、图8所示，该紧固件143还可以采用销轴固定，通过在转盘轴承140的外圈142和支撑框120上沿平行于固定孔121的轴线的方向开设通孔，并且绕固定孔121的周向开设多个通孔，然后通过多个销轴一一对应插入转盘轴承140的外圈142上的通孔以及对应的支撑框120上的通孔内，并且销轴的两端可以通过卡子限位，也可以通过点焊的方式固定，从而实现转盘轴承140的外圈142与支撑框120固定连接。
在一些实施例中，多个紧固件143可绕固定孔121的周向均匀分布，从而使整体受力均匀，避免转盘轴承140以及支撑框120的局部受力过大导致损坏的情况发生。
本公开提供的转盘轴承140的外圈142可以设置于支撑框120上的不同位置处，例如，可以设置于支撑框120的靠近滚动支撑部130的面上或者远离滚动支撑部130的面上，然后通过上述紧固件143将转盘轴承140的外圈142和支撑框120固定连接即可；如图9所示，也可以在固定孔121的内壁上开设凹槽122，凹槽122为环形结构并且与固定孔121同轴设置，如图10所示，转盘轴承140的外圈142固定于凹槽122内。相比于将转盘轴承140的外圈142固定于支撑框120的侧面上，将转盘轴承140固定于凹槽122内，能够使转盘轴承140不会凸出支撑框120的固定孔121外，从而减少支撑框120整体的厚度，有利于整体美 观。
需要指出的是，凹槽122为环形结构并与固定孔121同轴设置，是指凹槽122设置于固定孔121的孔壁上并且绕固定孔121延伸一周，从而形成的环形结构。
在一些实施例中，如图11、图12所示，凹槽122可以沿固定孔121的轴向延伸，并贯穿支撑框120的侧壁，即支撑框120的侧壁上形成一个凹陷结构，如图13、图14所示，该凹陷结构与固定孔121相互连通，相比于在固定孔121的孔壁上直接设置凹槽122，该结构使转盘轴承140安装更加方便，有利于降低加工难度。
在一些实施例中，如图5、图6所示，本公开提供的滚筒200包括筒体210和驱动盘220，筒体210的一端和驱动盘220均与转盘轴承140的内圈141固定连接，筒体210的另一端与滚动支撑部130抵接，齿圈230固定于驱动盘220上。电机310驱动齿圈230转动，使齿圈230能够带动驱动盘220以及筒体210转动，同时带动转盘轴承140的内圈141相对于外圈142转动，从而实现滚筒200整体相对于支撑框120转动。
需要指出的是，本公开提供的驱动盘220、筒体210均与固定孔121同轴设置。从而使整体结构更加紧凑，避免产生晃动。
并且，筒体210、驱动盘220与转盘轴承140的内圈之间的固定方式采用上述紧固件143固定或者采用焊接。
在一些实施例中，驱动盘220和筒体210可以同时设置于支撑框120靠近滚动支撑部130的一侧，同时，驱动机构300与驱动盘220设置于支撑框120的同一侧即可，从而驱动机构300能够与驱动盘220上的齿圈230传动，以带动驱动盘220和筒体210转动。
在一些实施例中，如图5、图6所示，驱动盘220和筒体210还可以分别设置于支撑框120的两侧并通过紧固件143固定连接，驱动盘220设置于支撑框120远离滚动支撑部130的一侧，因此，驱动机构300则设置在于驱动盘220对应的位置处，即支撑框120远离滚动支撑部130的一侧；相比于将驱动盘220和筒体210设置于支撑框120的同一侧，将驱动盘220和筒体210分别设置于支撑框120的两侧，能够避免驱动机构300与筒体210上安装的其他部件相互碰撞，阻止筒体210转动，从而更加使整体布局更加合理。
在一些实施例中，如图5、图6所示，齿圈230与驱动盘220同轴设置，且齿圈230固定于驱动盘220的圆周面上，以使齿圈230便于与 驱动机构300传动连接，并且不会增加驱动盘220的厚度，更加有利于整体美观。
如图6所示，本公开提供的滚动支撑部130为支撑轮，支撑轮的轴线与筒体210的轴线相互平行，筒体210沿其轴向远离支撑框120的一端与支撑轮抵接。通过支撑轮支撑筒体210远离支撑框120的一端，从而使筒体210远离支撑框120的一端与底座110之间实现相对滚动，即筒体210转动时，筒体210与底座110之间为纯滚动，筒体210带动支撑轮转动，从而使筒体210与支撑轮之间的滚动接触区域的摩擦力可忽略不计，以使筒体210转动更加轻松。
具体地，采用支撑轮作为滚动支撑部，支撑轮的固定轴即为前述固定部分，支撑轮的轮本体即为前述转动部分，支撑轮的轮本体能够相对于固定轴转动，因此，支撑轮的固定轴固定于底座110上远离支撑框120的一侧上，且固定轴与筒体210的轴线平行，筒体210远离驱动盘220的一端的圆周壁与轮本体抵接，从而使支撑轮起到支撑筒体210的作用，并且当筒体210转动时，支撑轮的轮本体绕固定轴转动，有利于减小筒体210转动时的摩擦力。
在一些实施例中，如图6所示，筒体210的轴线两侧分别设置有至少一个支撑轮，并且位于筒体210的轴线两侧的支支撑轮相对于筒体210的轴线对称设置。通过在底座110上对称设置至少两个支撑轮，从而使支撑轮与筒体210之间的支撑结构更加平衡，支撑更加稳固。
需要指出的是，筒体210的轴线两侧的支撑轮可以数量相等，也可以数量不同，因此，对于其具体数量不做限定。
另外，多个支撑轮均绕筒体210的周向分布，即多个支撑轮固定在底座110上时，是沿筒体210的圆周方向分布设置，从而当筒体210安装在底座110上时，每一个支撑轮均能够与筒体210抵接，从而能够将筒体210的重力分布于多个支撑轮上，每一个支撑轮均对筒体210形成支撑，进一步支撑轮对筒体210支撑的稳固性。
在一些实施例中，支撑轮为凸轮轴承，凸轮轴承的凸轮轴固定于底座110上，筒体210与凸轮轴承抵接。采用凸轮轴承作为辅助支撑，使筒体210与底座110之间能够相对滚动，从而减小筒体210转动时的摩擦力。
在一些实施例中，凸轮轴承的外圈与内圈之间还设置有偏心轴套，通过旋转能够调节凸轮轴承外圈与筒体210之间接触，从而控制凸轮轴 承与筒体210之间的接触刚度，进一步提高凸轮轴承支撑筒体210的稳固性。
并且，当达到刚度要求后锁紧螺母，并且做出防松标记，以便后续进行调整或者维修。
在一些实施例中，如图2、图6所示，本公开提供的底座110上还可以设置用于安装凸轮轴承的支撑块150，支撑块150设置有两个并且相对于筒体210的轴线对称设置，每个支撑块150上均安装有至少一个凸轮轴承，通过在底座110上设置支撑块150，并将凸轮轴承设置于支撑块150上，有利于增加筒体210与地面之间的距离，从而能够防止筒体210上的其他部件在转动至最低点的位置时，与地面发生碰撞的情况发生。
需要指出的是，支撑块150的作用是使凸轮轴承的安装位置升高，从而使筒体210升高，以避免筒体210上的其他部件与地面接触，因此，支撑块10固定于底座110远离支撑框120的一侧的顶面上，并且凸轮轴承设置于支撑块150朝向支撑框120的面上，而支撑块150的形状不做具体限定。
在一些实施例中，设置于筒体210的轴线的同一侧的至少一个凸轮轴承，可以设置为直径相同的凸轮轴承，并且绕筒体210的周向均匀分布设置，即多个凸轮轴承形成一个弧度，并且该弧度与筒体210同心设置，从而使每一个凸轮轴承均能够与筒体210抵接；也可以设置为直径不同的凸轮轴承，即多个凸轮轴承的直径逐渐增大，并且多个凸轮轴承的轴线可以处于同一个平面上，也可以处于不同的平面上，从而使每一个凸轮轴承均能够与筒体210抵接；因此，多个凸轮轴承只需分别与筒体210抵接即可，对于凸轮轴承的规格以及分布方式，在此不做具体限定。
为防止对机架组件整体进行维修时，滚筒200会转动，如图2所示，本公开提供的机架组件上设置有限位结构，限位结构设置于底座110和滚筒200之间，限位结构用于阻止滚筒200相对于底座110转动。通过限位结构能够阻止滚筒200转动，从而便于对于机架组件以及滚筒200上的其他部件进行维修。
在一些实施例中，限位结构可以设置于支撑框120与驱动盘220之间，通过限制驱动盘220转动，以使筒体210停止转动；也可以设置于筒体210与底座110之间，直接限制筒体210转动，以使驱动盘220停 止转动，从而便于对设备进行维修；相比于将限位结构设置于支撑框120和驱动盘220之间，将限位结构设置于底座110与筒体210之间，更加有利于将限位结构隐藏起来，有利于整体结构的美观。
如图2所示，本公开提供的限位结构包括插销、开设于筒体210上的第一限位孔211以及设置于底座110上的凸起160，第一限位孔211开设于筒体210远离驱动盘220的端面上，凸起160设置于底座110远离支撑框120的一侧，凸起160上开设有第二限位孔161，插销用于插入第一限位孔211和第二限位孔161内。当第一限位孔211和第二限位孔161处于对应位置时，通过将插销同时插入第一限位孔211和第二限位孔161内，由于底座110固定不动，因此一端插入第一限位孔211的插销同样固定不动，当插销的另一端插入凸起160上的第二限位孔161内，能够对筒体210形成限位，从而阻止筒体210相对于底座110转动。
需要指出的是，第一限位孔211与第二限位孔161处于对应位置是指，插销的两端能够同时插入第一限位孔211和第二限位孔161内的位置，以使插销能够限制筒体210相对于底座110转动。
示例性地，如图2所示，第一限位孔211和第二限位孔161的轴线均平行于筒体210的轴线，当筒体210转动至第一限位孔211的轴线与第二限位孔161的轴线重合的位置处，即为第一限位孔211与第二限位孔161位置对应，此时，插销可以依次插入第一限位孔211和第二限位孔161内，由于插销的作用，筒体210不能继续转动，从而能够保证对设备维修时，筒体210不会转动。
在一些实施例中，如图2所示，筒体210远离驱动盘220的端面上开设有多个第一限位孔211，并且多个第一限位孔211绕筒体210的周向分布。通过设置多个第一限位孔211，在需要将筒体210锁定时，只需使筒体210上距离第二限位孔161最近的一个第一限位孔211转动至对应位置即可，有利于减小转动的角度，作业更加方便。
本公开还提供了一种治疗设备，如图15所示，该治疗设备包括上述的机架组件、驱动机构300以及治疗头，治疗头设置于筒体210上，机架组件的支撑框120设置于治疗设备的前端。该治疗设备由于包括上述机架组件和驱动机构300，因此，能够解决相同的技术问题，并且取得相同的技术效果，在此不在详细赘述。
需要指出的是，本公开提到的治疗设备的前端，是指靠近治疗床的一侧，即患者平躺在治疗床上，从治疗设备的前端移动至治疗设备的治 疗腔内。
本公开提供的治疗设备，如图15所示，在驱动盘220远离支撑框120的面上设置有第一滑环240，第一滑环240与固定孔121同轴设置，在支撑框120上设置有第一电刷170，第一电刷170与第一滑环240抵接。通过将滑环设置于驱动盘220远离支撑框120的面上，即滑环设置于机架组件的前端，从而在对设备进行维护或者维修时，维修滑环的工作人员能够在机架100的前端进行维修，与在机架100后侧维修其他电器部件的工作人员不会相互冲突，能够使后侧具有更大的维修空间。
在一些实施例中，在滚筒200的后端面上还可以设置第二滑环，在底座110上设置第二电刷，第二电刷与第二滑环抵接。在滚筒200的两端均设置滑环，可以通过两个滑环分别传递电信号，也可以在一个滑环出现故障是，使用另一个滑环传递电信号，从而确保设备正常运行。
在一些实施例中，驱动机构300与第一电刷170电连接，即设置两个滑环时，由第一电刷170和第一滑环240传递电信号。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
