具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
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、B和C中的至少一个”与“A、B或C中的至少一个”具有相同含义，均包括以下A、B和C的组合：仅A，仅B，仅C，A和B的组合，A和C的组合，B和C的组合，及A、B和C的组合。
“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，其用于传递控制信号的滑环固定于滚筒200的后端面上，对应的电刷固定于底座110上，并且电刷与滑环相互抵接，当滚筒200转动时，即可通过电刷与滑环相互摩擦传递电信号。
由于滑环设置于滚筒200的后端，因此，对滑环进行维修，只能在设备的后侧进行，但是，对于设备上的其他部件的维修工作也同样是在设备的后侧进行，从而造成维修空间狭小，维修不方便等问题，影响工作效率并增加工作难度。
为解决上述问题，本公开实施例提供了一种机架组件，如图1所示，包括固定部和转动部，转动部转动设置于固定部上，转动部的前端面上设置有第一滑环240，第一滑环240相对于转动部固定，固定部上固定有第一电刷170，第一电刷170与第一滑环240抵接。
本公开提供的机架组件，如图1所示，由于将第一滑环240设置于转动部的前端面上，即第一滑环240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设备的前端进行维修，与在设备后端维修其他部件的工作人员不会相互影响，从而使维修人员在进行维修工作时，都能够具有较大的维修空间，有利于提高工作效率并且降低工作难度。
需要指出的是，本公开提供的固定部是用于固定在地面上的，而转动部则是转动设置于固定部上，即转动部能够相对于固定部转动，因此，固定部可以一些固定载体，而转动部则是通过转轴或者其他部件转动连接与固定载体上的部件。
在一些实施例中，在转动部的后端面上还可以设置第二滑环(图中未示 出)，在固定部上设置第二电刷，第二电刷与第二滑环抵接。即在转动部的两端面上均设置有滑环，在使用时，可以通过两个滑环共同传递电信号，也可以一个滑环传输信号，另一个滑环供电，还可以在一个滑环出现故障时，使用另一个滑环传递电信号，从而确保设备正常运行。
需要指出的是，本公开提供的第一电刷170和第二电刷的固定位置分别与对应的第一滑环240以及第二滑环对应，即能够使第一电刷170与第一滑环240抵接，第二电刷与第二滑环抵接即可，因此，对于第一电刷170和第二电刷的位置不做具体限定。
本公开实施例提供的第一电刷170和第二电刷可以直接固定于固定部上，如图1所示，也可以通过第一支撑件将第一电刷170固定于固定部上，通过第二支撑件(图中未示出)将第二电刷固定于固定部上。通过第一支撑件和第二支撑件分别将对应的第一电刷170以及第二电刷固定于固定部上，有利于减小电刷的体积，并且便于电刷与对应的滑环抵接。
在一些实施例中，如图1所示，第一支撑件和第二支撑件的作用是支撑，因此，只要能够起到支撑电刷作用的部件都可以，例如，可以是支撑杆，支撑杆的一端与固定部固定连接，另一端与电刷固定连接即可，支撑杆的结构简单，有利于降低成本；也可以是一个支撑方框，支撑方框的一侧与固定部固定连接，另一侧与电刷固定连接，支撑方框有利于提供支撑强度，使电刷固定更加稳固。
如图1所示，本公开实施例提供的机架组件还包括驱动机构300，驱动机构300与转动部传动连接且设置于靠近第一滑环170的一侧，驱动机构300与第一滑环170电连接。即驱动转动部带动第一滑环170转动时，能够向其他部件传递电信号，当电信号传递有故障时，工作人员在设备前端即可进行检查维修，施工更加方便。
在一些实施例中，如图1、图2所示，本公开提供的固定部包括机架100，转动部包括滚筒200，滚筒200可转动设置于机架100上，第一电刷170固定于机架100上，第一滑环240相对于滚筒200固定且设置于滚筒200的前端面上。通过将第一滑环240设置于滚筒200的前端面上，从而能够在设备的前侧对第一滑环240进行维修，以增加维修空间，提高工作效率。
本公开实施例提供的机架组件包括转动组件，如图1、图2所示，滚筒200通过转动组件转动设置于机架100上，转动组件设置于滚筒200的前端面上，第一滑环240设置于转动组件上，并可随滚筒200一同转动。滚筒200与机架100之间通过转动组件实现滚筒200相对于机架100转动，将第一滑 环240设置于转动组件上即可实现第一滑环240与滚筒200一同转动。
需要指出的是，转动组件由于需要使滚筒200能够相对于机架100转动，因此，转动组件至少包括能够相对转动两部分结构，其一部分与机架100固定连接，另一部分与滚筒200固定连接，从而实现二者相对转动，因此，第一滑环240设置于转动组件上与滚筒200固定连接的部分上。
示例性地，如图4、图5所示，本公开提供的转动组件包括转盘轴承140，转盘轴承140的外圈142与机架100固定连接，转盘轴承140的内圈141与滚筒200固定连接，如图1、图2所示，第一滑环240相对于转盘轴承140的内圈142固定。通过将第一滑环240相对固定于转盘轴承140的内圈142上，从而即可实现第一滑环240随滚筒200一同转动。
另外，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相对于机架100转动。
在一些实施例中，转盘轴承140的外圈142与机架100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的机架100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与机架100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2、图3所示，本公开提供的转动组件还包括齿圈230，转盘轴承140的内圈141设置于齿圈230和滚筒200的前端面之间，并且相互固定连接，第一滑环240相对于齿圈230固定，驱动机构300与齿圈传动连接。通过在转盘轴承140的内圈141上固定设置一个齿圈230，一方面将第一滑环240固定于齿圈230上，以使第一滑环240能够随滚筒200转动，另一方面将齿圈230与驱动机构300传动连接，从而通过驱动机构300即可驱动齿圈230、滚筒200以及第一滑环240转动，从而实现滚筒200带动第一滑环240整体相对于机架100转动，并且通过控制驱动机构300的开启与停止，即可控制滚筒200的 转动角度。
相关技术提供的治疗设备，由于底座110和滚筒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上的支撑部件精确配合，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2、图3所示，本公开实施例提供的机架组件，其机架100包括底座110，底座110的一侧设置有支撑框120，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沿其轴向的一端通过转盘轴承140可转动的设置于固定孔121内，滚筒200的另一端与滚动支撑部130抵接。
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。
具体地，如图4、图5所示，本公开提供的转盘轴承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。
本公开提供的转盘轴承140的外圈142与支撑框120之间可以通过焊接固定，也可以通过紧固件143固定连接。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，该紧固件143可以采用螺栓，如图4、图5所示，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，该紧固件143还可以采用销轴固定，如图4、图5所示，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，如图4、图5所示，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6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7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的侧面，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8、图9、图10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，如图5、图11所示，即支撑框120的侧壁上形成一个凹陷结构，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。
如图12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。驱动机构300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7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。
如图12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11、图12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13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13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，有利于整体的美观。
如图13所示，本公开提供的限位结构包括插销(图中未示出)、开设于筒体210上的第一限位孔211以及设置于底座110上的第二限位孔161，插销用于插入第一限位孔211和第二限位孔161内。也就是当滚筒200转动至第一限位孔211和第二限位孔161处于对应位置时，通过将插销的两端分别插入第一限位孔211和第二限位孔161内，由于底座110固定不动，因此，一端插入第二限位孔161的插销同样固定不动，当插销的另一端插入滚筒200上的第一限位孔211时，则能够对滚筒200形成限位，从而使滚筒200不能相对于底座110转动。
在一些实施例中，第一限位孔211和第二限位孔161的轴线可以形成一定夹角，此时，插销需要由相互形成夹角的两部分组成，从而当第一限位孔211与第二限位孔161处于对应位置时，插销的两端能够分别 插入对应的第一限位孔211和第二限位孔161内，进而能够阻止滚筒200相对于底座110转动。
具体地，第一限位孔211和第二限位孔161的轴线形成夹角是指，第一限位孔211和第二限位孔161的轴线不能重合，因此，插销需要由两部分组成，当其中一部分插入第一限位孔211时，其另一部分的轴线正好与第二限位孔161重合，从而能够将另一部分插入第二限位孔161内，以使插销的两端分别插入第一限位孔211和第二限位孔161，对滚筒200形成限位。
在一些实施例中，如图13所示，第一限位孔211和第二限位孔161的轴线也可以均平行于滚筒200的轴线设置，并且沿垂直于滚筒200的轴线的截面上，第一限位孔211和第二限位孔161的轴线位于同一个圆周上，在该结构下，插销可以采用一根直杆结构，当第一限位孔211和第二限位孔161处于对应位置时，插销依次插入第一限位孔211和第二限位孔161内即可，相比于形成夹角的结构，该结构下的插销可以使用任意的直杆结构的零件代替，适用性更加广泛，并且在插入插销时，更加简单方便。
需要指出的是，本公开提出的直杆结构的零件，需要采用刚度较强的零件，不能使用柔性材料，即能够承受较大的力而不会弯折或者折断的零件。
另外，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，第一限位孔211和第二限位孔161的轴线均平行于滚筒200的轴线的方案中，第一限位孔211和第二限位孔161的对应位置是指，第一限位孔211的轴线与第二限位孔161的轴线重合的位置，此时，插销即可依次插入第一限位孔211和第二限位孔161。
在一些实施例中，如图13所示，底座110上远离支撑框120的一侧的顶面上设置有凸起160，第二限位孔161开设于所述凸起160上，相比于直接将第二限位孔161开设于底座110上，设置凸起160后，第二限位孔161的高度增加，能够避免滚筒200设置太低，导致滚筒200上的其他部件(例如治疗头)与地面接触；并且凸起160的厚度不需要设置太厚，从而能够降低开设第二限位孔161的加工难度。
在一些实施例中，如图8、图9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。
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，相互之间需要碰撞，整体结构不合理。
本公开提供的机架组件，如图12、图13所示，驱动机构300与设置于驱动盘220上的齿圈230传动连接，即驱动机构300仅与滚筒200的一端传动连接，因此，可以将驱动机构300设置于滚筒200上设置有驱动盘220的一端，从而避免了驱动机构300与滚筒200上的其他部件相互碰撞，并且驱动机构300可以设置于距离齿圈230较近的位置，不需要通过传动轴连接，从而避免降低传动效率。
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。
本公开提供的机架组件，滚筒200的一端通过转盘轴承140与支撑框120上的固定孔121转动连接，滚筒200的另一端与底座110上的凸轮轴承(即滚动支撑部130)抵接，由转盘轴承140作为主支撑，多个凸轮轴承作为辅助支撑，由于筒体210、驱动盘220以及转盘轴承140的内圈141固定连接，因此，能够防止筒体210转动时沿轴向窜动，并且由凸轮轴承辅助支撑筒体210，筒体210转动时与凸轮轴承滚动接触的区域的摩擦力可以忽略不计，使滚筒200整体转动时，阻力较小，转动更加轻松方便。
如图12、图13所示，本公开提供的驱动机构300包括电机310和传动齿轮320，电机310的输出轴与传动齿轮320固定连接，传动齿轮 320与齿圈230啮合。由电机310通过传动齿轮320驱动齿圈230转动，从而使驱动盘220转动，并且带动筒体210一同转动，从而通过电机310的开启与停止，能够控制筒体210的转动角度。
并且，采用传动齿轮320传递扭矩，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。
在一些实施例中，本公开提供的驱动机构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的侧壁上，或者其他靠近齿圈230的位置均可，在此对于驱动机构300的具体位置不做限定。
为降低滚筒200转动的速度，如图12、图13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传动连接。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，如图12、图14所示，本公开提供的减速机构400可以为以下结构，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，以使驱动盘220和筒体210一同转动，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，从而使驱动盘220和筒体210的转速降低，进而便于精确控制滚筒200的转动角度。
在一些实施例中，如图13、图15所示，本公开提供的减速机构400还可以为以下结构，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传动连接。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，即降低了驱动盘220 和筒体210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13、图15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，链传动具有五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13、图15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。
本公开还提供了一种治疗设备，如图1所示，该治疗设备包括上述的机架组件以及治疗头(图中未示出)，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，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。
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。
