具体实施方式
为使本申请的技术方案和优点更加清楚，下面将结合附图对本申请实施方 式作进一步地详细描述。
需要说明的是，对于放射治疗设备，其辐射头包括但不限于：治疗头和成像头等，辐射头安装于机架上，机架上对应具有一安装位，以容纳辐射头。一般情况下，机架的安装位处具有两个安装侧板，用来与辐射头的两侧(一般是两侧的导轨)进行连接。可以理解的是，根据具体的放射治疗设备，其对应的辐射头命名有所不同，举例来说，对于伽马刀，其辐射头称为聚焦治疗头，对于直线加速器，其辐射头为加速器治疗头。
本申请实施例基于辐射头和机架的上述结构，提供了一种利于辐射头安装的安装机构，以下就其结构进行概述：
一方面，本申请实施例提供了一种安装机构，该安装机构可用于放射治疗设备的辐射头M的拆装。如附图1至附图3所示，该安装机构包括：分别与放射治疗设备的辐射头M两侧连接的两个侧支撑1；与侧支撑1顶部连接的顶支撑2，顶支撑2用于与机架N的顶部连接；与放射治疗设备的机架N连接，且位于侧支撑1和机架N之间的定位支撑3，其中定位支撑3的厚度可调。
本申请实施例提供的安装机构，应用时，通过顶支撑2与机架N顶部连接，来将辐射头M初步安装于机架N上。由于定位支撑3与机架N连接，此时定位支撑3位于侧支撑1与机架N之间，通过对定位支撑3的厚度进行调节，直至消除侧支撑1和机架N之间的安装间隙，即，侧支撑1和定位支撑3之间彼此紧密贴紧，此时，可利用定位支撑3来为辐射头M提供侧向支撑，有效提高辐射头M的安装刚性，使辐射头M获得较高的安装精度。随后，可以将辐射头M与机架N进行后续紧固连接即可。可见，基于本申请实施例的安装机构进行的安装过程，能够获得良好的安装刚性，同时可保证良好的安装精度，安装过程中无须反复拆装辐射头M，显著简化了安装过程，降低了安装难度。
本申请实施例中，定位支撑3可有效提高辐射头M安装时的刚性，在使用状态下对辐射头M进行稳定的侧向支撑。为了实现定位支撑3的厚度可调，以下就其适用的结构进行概述：
示例地，如附图4所示，定位支撑3包括：与机架N(例如，图3中机架N的安装侧板P)连接的第一固定块301；以及相对于第一固定块301滑动的第一厚度调节块302。进一步地，如附图2所示，该安装机构还包括：用于驱动第一厚度调节块302双向滑动的第一驱动件7。
应用过程中，第一固定块301可固定连接于机架N的安装侧板P上，第一 厚度调节块302与第一固定块301构成一个滑动副，通过第一驱动件7驱动第一厚度调节块302沿着第一固定块301双向滑动，可以增加或减小定位支撑3的厚度，从而达到消除或恢复侧支撑1与机架N的安装侧板P之间安装间隙的目的。
对于第一厚度调节块302相对于第一固定块301的滑动，可以在两者的接触面上设置相适配的滑槽和滑轨，例如，可以在第一厚度调节块302上设置滑轨，在第一固定块301上设置滑槽，通过滑轨和滑槽的配合，实现上述相对滑动。可以理解的是，滑槽的长度大于滑轨的长度，以便于第一厚度调节块302沿第一固定块301进行双向滑动。
其中，考虑到第一固定块301与机架N的安装侧板P紧密贴合，而第一厚度调节块302需要与侧支撑1紧密贴合(参见附图5)，当侧支撑1为平面板状结构时，期望第一厚度调节块302与其贴合的表面也为平面。这样，为了能够实现第一厚度调节块302沿第一固定块301进行双向滑动时，不仅能够达到厚度变化的目的，同时还确保第一固定块301和第一厚度调节块302之间始终紧密贴合，本申请实施例中，如附图4所示，第一固定块301和第一厚度调节块302为相适配的楔形块，这样可以使第一厚度调节块302与侧支撑1楔紧，形成侧向支撑。
举例来说，第一固定块301可以为矩形轮廓的楔形块，其厚度可以自顶部至底部逐渐减小，第一厚度调节块302也可以为矩形轮廓的楔形块，其厚度可以自顶部至底部逐渐增大。也就是说，第一固定块301和第一厚度调节块302的贴合面为相适配的斜面。
上述提及，利用第一驱动件7来驱动第一厚度调节块302的双向滑动，作为一种示例，可以使第一驱动件7与第一厚度调节块302螺纹连接，通过原位转动第一驱动件7，并通过改变转动方向即可实现第一厚度调节块302的双向滑动。
其中，第一驱动件7可以限位于顶支撑2上，以确保原位转动。示例地，第一驱动件7可以为螺栓，其可以穿过顶支撑2与第一厚度调节块302螺纹连接，并且，基于其头部的限位作用，其可以始终限位于顶支撑2上，达到可以转动但是不可轴向移动的目的。同时，当采用螺栓时，其可以保持第一厚度调节块302与侧支撑1始终呈楔紧状态，进而确保侧支撑1与机架N的安装侧板P之间始终呈楔紧状态。
进一步地，可以在顶支撑2上设置增强块9，使第一驱动件7同时穿过增强块9以及顶支撑2来与第一厚度调节块302螺纹连接，这样可以增加连接位置处的强度。其中，增强块9可以是板状结构。
进一步地，本申请实施例提供的安装机构还可包括：与机架N连接，且位于侧支撑1和机架N之间的卸荷支撑4。该卸荷支撑4上具有滚动件401，滚动件401用于与侧支撑1形成滚动摩擦。其中，卸荷支撑4的厚度可调。
卸荷支撑4和定位支撑3配合，可用于辐射头M的拆卸以及再安装过程。示例地，辐射头M拆卸时，旋转机架N，使辐射头M位于机架N的侧部(即，辐射头M的中轴线沿水平方向延伸)。解除顶支撑2与机架N顶部的初步安装，对定位支撑3的厚度进行调节，直至恢复侧支撑1和机架N之间的安装间隙，即，定位支撑3与侧支撑1分离，以方便拆卸。随后，对卸荷支撑4的厚度进行调节，以消除侧支撑1与机架N之间的间隙，利用卸荷支撑4来为辐射头M提供侧向支撑，使辐射头M相对于机架N保持良好的定位(该过程相当于将定位支撑3切换为卸荷支撑4)。由于卸荷支撑4上具有滚动件401，滚动件401用于与侧支撑1形成滚动摩擦，基于上述滚动摩擦，在解除辐射头M与机架N之间的紧固连接后，利用辐射头拆卸工装能够将辐射头M由机架N中顺利拉出(可以理解的是，辐射头M与安装机构的侧支撑1和顶支撑2一同拉出机架N)。当辐射头M再安装时，只需原路返回，并将卸荷支撑4切换为侧支撑1，即可确保再安装的辐射头M的安装精度。
可见，通过使定位支撑3和卸荷支撑4进行切换，可以将辐射头M的安装状态(也即定位支撑3进行作用)切换为拆卸状态(也即卸荷支撑4进行作用)，通过上述切换，可以保证辐射头M在拆卸后再安装时，始终保持良好的安装精度。可见，在保持安装精度的前提下，实现了辐射头M从机架N上的拆卸，进而使得对辐射头M的各项作业，例如，部件维修或换源等更加方便可行，对于降低放射治疗设备的体积以及成本具有重要的意义，有效提高了产品竞争力。
侧支撑1可用来与辐射头M两侧的导轨连接，根据导轨的形状，可以在侧支撑1上设置于导轨形状相适配的连接位。一般情形下，辐射头M两侧的导轨为半圆弧形，此时，可以在侧支撑1上设置半圆弧形的连接槽作为连接位，在导轨卡入该连接位内进行初步定位后，采用紧固件(例如螺钉)将导轨与连接位进行紧固连接即可。
定位支撑3和卸荷支撑4均可以与机架N的安装侧板P连接，此时，侧支 撑1位于辐射头M的导轨和机架N的安装侧板P之间，为了使侧支撑1与机架N的安装侧板P之间进行紧密贴合，侧支撑1可以为板状结构。同样地，顶支撑2也可以为板状结构。为了提高安装机构的强度，侧支撑1与顶支撑2可以一体成型。
对于卸荷支撑4来说，其可以同时位于机架N的两个安装侧板P上，也可以仅位于其中一个安装侧板P上，考虑到仅位于一侧也能够达到良好的卸荷作用，本申请实施例中，可以使卸荷支撑4仅设置于机架N一侧的安装侧板P上。
上述提及，卸荷支撑4用来在辐射头M拆卸时对其进行侧向支撑，为了实现卸荷支撑4的厚度可调，以下就其适用的结构进行概述：
示例地，如附图6所示，卸荷支撑4包括：与机架N(例如，图3中机架安装侧板P)连接的第二固定块402；以及，相对于第二固定块402滑动的第二厚度调节块403。其中，滚动件401位于第二厚度调节块403上。
进一步地，该安装机构还包括：用于驱动第二厚度调节块403双向滑动的第二驱动件8。
应用过程中，第二固定块402可固定连接于机架N的安装侧板P上，第二厚度调节块403与第二固定块402构成一个滑动副，通过第二驱动件8驱动第二厚度调节块403沿着第二固定块402双向滑动，可以增加或减小卸荷支撑4的厚度，从而达到消除或恢复侧支撑1与机架N的安装侧板P之间间隙的目的。
其中，第二厚度调节块403与第二固定块402之间的相对滑动方式可以参见上述就第一厚度调节块302与第一固定块301的阐述，在此不再赘述。另外，第二固定块402和第二厚度调节块403也可以为相适配的楔形块。
第二驱动件8与第二厚度调节块403螺纹连接，以达到使第二厚度调节块403双向滑动的目的。示例地，第二驱动件8也可以为螺栓。
同样地，第二驱动件8也可以同时穿过增强块9以及顶支撑2来与第二厚度调节块403螺纹连接，以增加连接位置处的强度。这样，可以使卸荷支撑4与同侧的定位支撑3毗邻而设。
本申请实施例中，滚动件401用来与侧支撑1之间形成滚动摩擦，作为一种示例，滚动件401包括：固定于第二厚度调节块403上的固定本体4011，以及可转动地设置于固定本体4011上的多个滚珠4012。通过滚珠4012与侧支撑1形成滚动摩擦即可。可以理解的是，滚动件401的结构可以参照算盘的结构，在此不再详述。
为了使定位支撑3和卸荷支撑4的功能更加优化，可以同时设置多个定位支撑3和卸荷支撑4，在一种可能的实现方式中，在机架N的每一侧的安装侧板P上，均可以设置多个定位支撑3，例如，2个、3个(参见图1)或4个等。同时，在机架N的任一侧的安装侧板P上，可以设置多个卸荷支撑4，例如，2个、3个(参见图1)或4个等。
为了快速有效地使辐射头M获得较高的安装精度，所述安装机构还包括：与侧支撑1的顶部连接的顶支撑2；位于顶支撑2上的第一定位件201；位于机架N顶部的第二定位件202。其中，第一定位件201与第二定位件202一一对应。
辐射头M于机架N上进行初步安装时，通过使顶支撑2上的第一定位件201与第二定位件202一一对应，两者配合，实现辐射头于机架上的位置定位，提高安装精度。在定位完成后，使顶支撑2与机架N连接实现辐射头于机架上的位置固定。通过上述第一定位件201和第二定位件202，在使辐射头M初步安装于机架N上时，即可获得高安装精度，随后利用定位支撑3来调节辐射头M的安装刚性，如此设置，可以在快速高效地达到高安装精度和安装刚性的前提下，避免了反复拆装重量较重的辐射头，显著简化了安装过程，降低了安装难度。
其中，机架N可以承托顶支撑2，同一顶支撑2上第一定位件201的数目可以不止一个，例如，可以为两个或三个等。可以理解的是，第二定位件202的数目与第一定位件201的数目相同。
上述提及，通过第一定位件201与第二定位件202对应实现辐射头在安装过程中的定位，第一定位件201与第二定位件202之间进行连接，即可实现顶支撑2与机架N顶部的连接，对于两者之间的定位连接方式，包括但不限于：插接连接、螺栓连接、焊接连接或卡扣连接等，而为了实现快速且有效地连接，可以选用插接连接。以下分别就上述几种连接方式进行阐述：
对于螺栓连接方式，第一定位件201和第二定位件202可以均为螺栓孔，应用时，使第一定位件201与第二定位件202一一对应导通，采用螺栓与两者螺纹连接，即可实现有效定位，同时实现顶支撑2与机架N顶部的连接。
对于焊接连接方式，第一定位件201和第二定位件202可以均为指示标，应用时，使第一定位件201与第二定位件202一一对应重叠，然后将顶支撑2与机架顶部焊接，即可实现有效定位，同时实现顶支撑2与机架N顶部的连接。
对于卡扣连接方式，第一定位件201可以为卡槽，第二定位件202可以为卡箍，应用时，使第二定位件202卡入第一定位件201内，即可实现有效定位，同时实现顶支撑2与机架N顶部的连接。
对于插接连接方式，其具有定位方式简单、快速和可靠的优点，作为一种示例，第一定位件201为插孔，第二定位件202为插块，当然不排除第一定位件201为插块，而第二定位件202为插孔的情形。
作为一种示例，插块可以为销钉，插孔可以为销孔。
一般情况下，插块的结构与插孔相适配，举例来说，当插孔为圆形孔时，插块为圆柱块；当插孔为菱形孔时，插块为菱形柱。
其中，插块的外轮廓可以与插孔的内轮廓恰好适配，以达到稳定的定位效果。插块的外轮廓体积也可以小于插孔的内轮廓体积，举例来说，插孔的径向宽度可以大于插块的径向宽度，在该种情形下，本申请实施例提供的定位机构还包括：可移动地安装于第一定位件201(即，插孔)内的调节件，调节件上具有与第二定位件202适配插接的安装孔。
通过使第一定位件201(插孔)的径向宽度大于第二定位件202(插块)的径向宽度，并使调节件在插孔内可移动，可以进一步适当调节辐射头在机架上的位置，以确保获得更高的安装精度。通过在调节件上设置安装孔，用来与插块适配插接，实现第一定位件201与第二定位件202之间的相对固定。
对于调节件来说，其包括：可移动地位于第一定位件201内部的调节本体，以及与调节本体端部连接的固定体。调节本体上具有安装孔，该固定体用于使调节本体固定于第一定位件201(插孔)内部。
通过调节本体来插孔内移动，来最终调节辐射头在机架上的位置。通过固定体，在上述位置关系确定后，将调节件相对于插孔固定，进而确保辐射头相对于机架固定。
举例来说，固定体可以为围设于调节本体端部的板状结构，此时，可以通过螺钉将固定体固定于顶支撑上，以使调节件相对于插孔固定。
由上述可知，两个侧支撑1可以是分离的，并且相对独立，为了简化定位机构的结构且增加其强度，如附图1所示，该定位机构还包括：两端分别与两个侧支撑1连接的加强支撑5。
举例来说，该加强支撑5可以是连杆结构，可以设置为一个或两个，两端分别与两个侧支撑1的同侧端连接。
进一步地，还可以使加强支撑5的长度可调，以使该定位机构适应多种规格的辐射头M。
上述提及，辐射头M相对于机架N实现精确定位后，将辐射头M与机架N进行紧固连接即可，一般情形下，辐射头M的导轨与机架N的安装侧板P通过连接螺钉进行连接，考虑到在应用状态下，侧支撑1夹紧于导轨与安装侧板P之间，所以，如附图4所示，侧支撑1和定位支撑3上可以具有导通的过孔6，用于使安装侧板P和导轨的连接螺钉穿过，这样对于增加上述紧固性能具有重要的意义。
进一步地，可以使该过孔6具有一定的长度，长度方向可以沿侧支撑1的轴向，例如，可以为腰型孔，这样不仅便于同时使用多个连接螺钉，还可以提高进行上述紧固连接时的便利性。
另一方面，本申请实施例还提供了一种放射治疗设备，该放射治疗设备包括：本申请实施例提供的任一种安装机构；
聚集辐射头，其中，辐射头的导轨与安装机构的侧支撑连接；
机架，其中，机架的安装侧板与安装机构的定位支撑连接。
针对上述提供的放射治疗设备，以下就辐射头的安装与拆卸过程进行阐述：
辐射头的安装：
首先，将安装机构的定位支撑的第一固定块与机架的安装侧板连接，使安装机构的两个侧支撑与辐射头两侧的导轨进行连接，随后与机架初步安装，具体是使顶支撑与机架的安装侧板顶部在第一定位件和第二定位件的定位作用下进行连接，实现辐射头在机架上的精确定位以及初步安装。
通过第一驱动件驱动第一厚度调节块运动，使定位支撑的厚度增加，直至消除侧支撑和机架的安装侧板之间的安装间隙(即，使第一厚度调节块与侧支撑楔紧)，利用定位支撑来为辐射头提供侧向支撑，使辐射头相对于机架实现固定。然后，利用连接螺钉，将辐射头的导轨与机架的安装侧板进行紧固连接即可。以上安装过程能够获得良好的安装精度，确保了辐射头上的多颗放射源始终聚焦于等中心点。
辐射头的拆卸：
旋转机架支架带动机架转动，使辐射头位于机架的侧部(即，辐射头的中轴线沿水平方向延伸)。解除辐射头在机架上的初步安装。
通过第一驱动件驱动第一厚度调节块反向运动，使定位支撑的厚度减小， 直至恢复侧支撑和机架的安装侧板之间的间隙(即，使第一厚度调节块与侧支撑分离)，以方便拆卸。随后，对位于机架的安装侧板以及辐射头的导轨之间的卸荷支撑的厚度进行调节，具体是通过第二驱动件驱动第二厚度调节块沿第二固定块滑动，使卸荷支撑的厚度增加，以消除侧支撑与机架的安装侧板之间的间隙(即，使第二厚度调节块与侧支撑楔紧)，利用卸荷支撑来为辐射头提供侧向支撑，使其相对于机架保持良好的定位(该过程相当于将定位支撑切换为卸荷支撑)。由于卸荷支撑上具有滚动件，滚动件用于与侧支撑形成滚动摩擦，基于上述滚动摩擦，在解除辐射头与机架之间的紧固连接后，利用辐射头拆卸工装能够将辐射头由机架中顺利拉出(可以理解的是，辐射头与安装机构的侧支撑和顶支撑一同拉出机架)。当辐射头再安装时，只需原路返回，并将卸荷支撑切换为侧支撑，即可确保再安装的辐射头的安装精度。
辐射头拆卸工装及其拆装辐射头的操作工艺为本领域所常见的，以下举例说明：
辐射头拆卸工装的底座固定在机架侧部的地基之上，通过螺钉与地基可靠连接。辐射头拆卸工装具有三个正交方向的直线运动，用于调整辐射头姿态，辐射头拆卸工装与机架连接，保持机架在拆卸过程中的平衡。辐射头拆卸工装上的水平导轨伸入机架内部辐射头的导轨下方。
拆卸过程中，通过调整辐射头拆卸工装高度，使其上水平导轨紧贴辐射头的导轨，和卸荷支撑共同托举辐射头。而辐射头拆卸工装上的水平丝杆通过转接板和辐射头的导轨固定。手摇水平丝杆，即可将辐射头沿水平方向移动出机架。
以上所述仅是为了便于本领域的技术人员理解本申请的技术方案，并不用以限制本申请。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
