其中，所述旋转装置21包括旋转件211和与旋转件211连接的旋转平台212，所述升降装置22与所述旋转平台212连接，并可随着旋转平台212一起转动。其中，所述旋转平台212可以在第一位置和第二位置之间转动。且，所述支撑平台具有第一边缘101，旋转平台212在第二位置时，加速器本体1在支撑平台100表面所在面的投影位于支撑平台100的第一边缘101之外，旋转平台212在支撑平台100表面所在面的投影位于支撑平台100的第一边缘101之内。且此时，加速器本体1可在升降装置22作用下上下移动，进。而可调其高度。在一个方案中，旋转平台212在第一位置时，加速器本体1在支撑平台100表面所在面的投影至少部分位于支撑平台100的第一边缘101之内。优选为，旋转平台212在第一位置时，加速器本体1在支撑平台100表面所在面的投影全部位于支撑平台100的第一边缘101之内。其中，所述支撑平台100为车辆时，所述第一边缘101为车体长度方向的后边缘。
采用本申请的方案，通过旋转装置21和升降装置22的作用，加速器本体1可以在 支撑平台100内部和外部进行位置切换，在运输中可以使得加速器本体1位于支撑平台100内部位置，方便运输并减小了平台长度。在工作时，可以使得加速器本体1位于支撑平台100外部，方便加速器本体1适应于不同高度的工作位置。
在一个方案中，在旋转平台212位于第二位置时，加速器本体1在支撑平台100表面所在面的投影紧邻支撑平台100的边缘。例如，加速器本体1在支撑平台100表面所在面的投影与支撑平台100的边缘的距离为5-20厘米。
采用这样的方案，在第二位置时加速器本体1紧靠支撑平台100的边缘设置，保证了工作时整个设备的尺寸也不过大。
如图4-5所示，在一个方案中，所述旋转装置21还包括旋转配合件213，所述旋转件211可以相对于旋转配合件213发生相对转动。其中，所述旋转配合件213设置在所述支撑平台100上。在一个方案中，所述旋转装置21还包括旋转驱动件214，用于驱动所述旋转件211相对于旋转配合件213相对转动。其中，所述旋转驱动件214可以是电机或液压马达以及配套的减速装置和齿轮等。在一个方案中，所述旋转件211与旋转平台212为一体结构。
在一个方案中，所述旋转驱动件214可以设置在所述旋转平台212内部或外部(图中未示出)。
在一个方案中，如图4所示，所述旋转件211为一环形结构，旋转配合件213具有容纳空间，使得旋转件211可放置于旋转配合件213的容纳空间之内；所述环形结构内表面具有齿，用于与旋转驱动件214的齿轮相配合；旋转件211环形结构的外表面以及旋转配合件213的容纳空间的内表面均为光滑结构，使得旋转件211环形结构的外表面以及旋转配合件213的容纳空间的内表面相对转动滑动。在一个方案中，在旋转件211环形结构的外表面以及旋转配合件213的容纳空间的内表面之间设置有滚动件(例如滚珠或者滚动锥形件)。这样，在旋转驱动件214的驱动下，旋转件211可以相对于外侧的旋转配合件213发生转动，进而带动旋转平台212转动。
在一个方案中，如图5所示，所述旋转件211为一环形结构，旋转配合件213具有轴结构，旋转件211环形结构的内表面以及旋转配合件213的轴表面均为光滑结构，旋转件211套在旋转配合件213的轴的外侧，并且发生可相对转动。所述环形结构外表面具有齿结构，用于与旋转驱动件214的齿轮相配合。在一个方案中，在旋转件211环形结构的内表面以及旋转配合件213的轴外表面之间设置有滚动件(例如滚珠或者滚动锥形件)。这样，在旋转驱动件214的驱动下，第一旋转211可以相对于旋转配合件213 发生转动，并带动旋转平台212转动。这样，在旋转驱动件214的驱动下，第一旋转211可以相对于内侧的旋转配合件213发生转动，进而带动旋转平台212转动。
如图6-7所示，在一个方案中，升降装置22包括滑动件221、升降导轨222以及升降驱动装置223。其中，在升降驱动装置的作用下，滑动件221和升降导轨222之间可发生相对位移。
其中滑动件221和升降导轨222这两者之一分别与旋转平台212和加速器本体1连接。这样，可以实现加速器本体1相对于旋转平台212的相对移动，进而可调整加速器本体1的工作位置。
在一个方案中，升降驱动装置223为气缸、油缸、齿轮、链轮链条等结构，其可以控制加速器本体1在任一个位置停留。
具体地，升降驱动装置223包括固定端以及可相对固定端伸缩的伸缩端，其中，固定端与旋转平台212连接，伸缩端与滑动件221连接。
在一个方案中，所述升降导轨222为一截面为U形的结构，包括一个底壁和与底壁的两侧连接的第一侧壁和第二侧壁。所述滑动件221在所述底壁和两个侧壁形成的包围空间内滑动。在一个方案中，所述底壁与旋转平台221连接。
在一个方案中，在所述升降导轨222的底壁和至少一个第一侧壁上设置有轴承224，在所述滑动件221上设置有容纳所述轴承224的凹槽225。所述凹槽225截面为U形，凹槽225的两侧壁与轴承224的表面配合。通过轴承224和凹槽225的配合，使得轴承224可在凹槽225做升降移动的同时，限制了轴承224在垂直于升降移动方向的移动，进而限制了滑动件221在垂直于升降移动方向的移动(当升降运动为竖直方向时，限制了水平方向的运动)。在一个方案中，在第一侧壁和第二侧壁上均设置有轴承224，相应地，在滑动件221表面对应轴承224位置均形成有凹槽225。在一个方案中所述每个侧壁和底壁上的轴承数量可以为两个或更多个。
采用这样的方案，通过轴承224与凹槽225的配合在保证滑动件221可沿着升降导轨直线移动的同时，还提供了抵抗加速器本体1的重力施加给滑动件221和升降导轨222连接点作用力的反作用力，避免了滑动件221脱离导轨造成设备的损坏。
在一个方案中，轴承224和凹槽225的设置位置可以对调，即轴承224设置在滑动件221上，凹槽225形成在升降导轨223上。
如图7、8，在一个方案中，在旋转平台212与升降装置22之间还设置有调节机构23，所述调节机构用于调整所述升降装置22与旋转平台212之间的位置关系，包括距离 角度等。
在一个方案中所述调节机构23包括三个调节单元231，三个调节单元231呈三角形布置，每一所述调节单元231均为长度可伸缩装置，其一端连接在旋转平台212上，另一端连接所述升降装置22上(滑动件221或升降导轨222之一上)。通过调整三个调节单元的伸缩量，可以调整所述升降装置22相对于旋转平台212之间的距离、倾斜角度或者俯仰角度等。
例如，当三个调节单元231均伸缩同样长度时，所述升降装置22相对于旋转平台212整体平动，这样可以调整两者之间的距离。这样在工作时，可以对应调整加速器本体1相对于第一边缘101的位置关系，避免了发生干涉或者距离过大。
当调整一个或两个调节单元231的长度时，则升降装置22会发生相应的偏转，这样会产生倾斜或俯仰，进而可以调整加速器本体1相对于支撑平台100的角度。进而可以方便适应被扫描物以及检测装置的实际情况，避免了射线的损失，提高了检测精度。
在一个方案中，至少一个所述调节单元231的两端通过铰接方式与所述旋转平台212和升降装置22连接。采用这样的方案，在调整加速器本体的倾斜角度或者俯仰角度时，调节范围更广，且调整更加灵活可靠，避免了相互之间可能产生的干涉。
在一个方案中，包括四个所述调节单元231，所述四个调节单元231呈矩形排布。这样的方案，角度的调整更加方便。
在一个方案中，所述调节单元231为螺栓和螺母的组合结构，另一个方案中为螺母丝杠结构或者气缸、油缸。
本申请还提供一种车载式辐射成像设备，其包括车辆以及所述的加速器，其中，所述加速器本体1通过所述升降装置22和旋转装置21与所述车辆连接。
在一个方案中，在旋转平台212位于第二位置时，下方设置有支撑装置，用于在旋转件211之外的部位对旋转平台支撑，以分担旋转件211所承受的力。其中，所述支撑装置和旋转平台212相接触的表面均为光滑结构。在另一方案中，在支撑装置和旋转平台212之间设置有滚动件。在另一个方案中，在旋转平台212位于第一位置时，其下方也设置有支撑装置。

其中，所述旋转配合件213设置在所述车辆100上，其具有容纳空间。所述旋转件211为一环形结构，且旋转件211可放置于旋转配合件213的容纳空间之内。其中旋转件211的环形结构内表面具有齿，用于与旋转驱动件214的齿轮相配合；旋转件211环形结构的外表面以及旋转配合件213的容纳空间的内表面均为光滑结构，使得旋转件211环形结构的外表面以及旋转配合件213的容纳空间的内表面相对转动滑动。
所述升降装置包括滑动件221、升降导轨222以及升降驱动装置223。在升降驱动装置的作用下，滑动件221和升降导轨222之间可发生相对位移。其中，滑动件221与加速器本体1固定连接，升降导轨222通过调节机构23与旋转平台212连接。
所述升降导轨222为一截面为U形的结构，包括一底壁和与底壁两侧连接的第一侧壁和第二侧壁。所述滑动件221可在所述底壁和两个侧壁、形成的包围空间内滑动。
在所述升降导轨222的底壁、第一侧壁和第二侧壁上分别设置有轴承224，在所述滑动件221上设置有容纳所述轴承224的凹槽225。其中，所述凹槽225截面为U形，凹槽225的两侧壁与轴承224的表面配合。通过轴承224和凹槽225的配合，使得轴承224可在凹槽225做升降移动的同时，限制了轴承224在垂直于升降移动方向的移动，进而限制了滑动件221在垂直于升降移动方向的移动
所述调节机构23包括四个调节单元，每一所述调节结构均均为长度可伸缩装置，其一端铰接在旋转平台212上，另一端铰接在所述升降导轨222上。通过调整四个调节单元的伸缩量，可以调整所述升降装置22相对于旋转平台212之间的距离、倾斜角度或者俯仰角度等。
下面结合附图说明本申请实施例1方案的工作过程：
如图1-3所述，在非工作状态(例如运输状态时)，所述旋转平台212位于第一位置，所述加速器本体1在车辆上。
当需要调整到工作状态时，旋转驱动装置214工作，使得旋转件212相对于旋转配合件213发生转动，进而带动旋转平台212旋转一定角度(例如90度)，到达第二工作 位置，此时，旋转平台212位于车辆的第一边缘101之内，加速器本体1随之转动到位于车辆的第一边缘101之外，如图10-12所示
升降驱动装置223开始动作，使得滑动件221相对于导轨222相对运动，带动加速器本体1向下移动，逐渐到达工作位置，如图13-14所示。
当需要调整加速器本体1相对于旋转平台212的距离和/或倾斜角度时，根据情况控制所述调节单元231中的至少一个，使得导轨222发生动作，进而带动加速器本体1到达所需的位置。
当工作完毕，加速器本体1需要从工作状态调整到非工作状态时，则首先，升降驱动装置223开始动作，使得滑动件221相对于导轨222相对运动，带动加速器本体1向上移动，使得加速器本体1的底面到达车辆上方。
随后旋转驱动装置214工作，使得旋转件212相对于旋转配合件213发生转动，进而带动旋转平台212旋转一定角度(例如90度)，到达第一工作位置。
