具体实施方式
现结合附图对本公开进行说明：
如图1、图2和图3所示，一种基于双动力驱动的平行移动架，可以包括：
机架1；
上横杆22，其两端可以通过端部固定件分别与机架1可调节地固定，上横杆22可以固定有上滑块21和上动力驱动装置2，上动力驱动装置2能够驱动上滑块21仅沿着上横杆22来回移动；
下横杆62，其两端可以分别与机架1可调节地固定，下横杆62与上横杆22可以基本上平行设置，下横杆62可以固定有下滑块61和下动力驱动装置，下动力驱动装置能够驱动下滑块61仅沿着下横杆62来回移动；
竖向杆31，其顶部可以经上调节装置与上滑块21联接、底部可以经下调节装置与下滑块61联接；
控制器，其可以分别电连接上动力驱动装置2和下动力驱动装置的电机；
当上滑块21和下滑块61带动竖向杆31朝同一方向移动时，上调节装置能使竖向杆31相对于上横杆22旋转一个角度，下调节装置能使竖向杆31相对于下横杆62旋转一个角度；上调节装置能使竖向杆31相对于上横杆22上下移动一段距离，和/或，下调节装置能使竖向杆31相对于下横杆62上下移动一段距离。
需要说明的是，在双动力驱动的平行移动架的整体结构中，由于存在上横杆22、下横杆62和竖向杆31的变形、安装误差和/或同步误差等，竖向杆无法始终保持完全平行地移动，竖向杆31的同一侧(例如左侧、或右侧)相对于上横杆22和/或下横杆62会有微小转动的角度，即竖向杆31的同一侧相对于上横杆22和/或下横杆62所呈角度不为理想情况下的90度，例如该偏转角度可能会是正偏差，即竖向杆31的同一侧相对于上横杆22和/或下横杆62所呈角度例如大于90度，该偏转角度也可能会是负偏差，即竖向杆31的同一侧相对于上横杆22和/或下横杆62所呈角度例如小于90度，且该偏转角度始终是在变化的，当竖向杆自身长度比较长时，其两端分别由两个驱动装置驱动进行运动所产生的扭矩非常大，该扭矩很容易损坏竖向杆31与上横杆22和下横杆62的刚性联接件，另外，偏转角度的存在使得竖向杆31在与上横杆22的联接点和与下横杆62的联接点之间的长度存在发生变化的趋势，有了上调节装置和下 调节装置，竖向杆31相对于上横杆22和/或下横杆62能自适应的旋转一个角度和上下移动一段距离，以便消除扭矩以及消除应力，从而保护滑块等不会损坏。
可选地，如图5、图6所示，上调节装置或者下调节装置可以包括：
调节板71，其可以开设有调节孔711，调节板71的一端可以与上滑块21或下滑块61固定；显然，上调节装置对应上滑块21，下调节装置对应下滑块61；

本发明实施例提供了通过调节装置能够旋转一个角度的具体方式。
由于部件材料硬度相近且它们之间可能发生相对运动，会产生摩擦导致损坏竖向杆31、上滑块21和下滑块61，为此，上调节装置或者下调节装置还可以包括：
柔性隔离柱73，其可以开设有圆环腔和通孔，柔性隔离柱73可以嵌入调节柱72的圆环槽，调节板71的一部分可以嵌入圆环腔，柔性隔离柱73能将调节板71与调节柱72间隔开，有了柔性隔离柱73，能有效保护竖向杆31、上滑块21和下滑块61，通常，柔性隔离柱73属于易损件，但其可以更换。
可选地，调节柱72可以由两部分构成，调节柱72的两个部分通过紧固件被紧固在一起，以便于柔性隔离柱73的安装与更换。
可选地，柔性隔离柱73可以由塑料制成，塑料可选用四氟材料或聚丙烯等，其具有光滑和硬度适中的特点，上横杆22和下横杆62可以选用铝型材，其相对于柔性隔离柱73比较硬。
可选地，上调节装置和下调节装置中至少一只调节板71的调节孔711可以为长形孔，调节柱72能在长形孔内上下移动，这给出了实现竖向杆31上下移动一段距离的结构的可选实施例。
可选地，如图7所示，上动力驱动装置2可以包括：
上横杆22，其可以为中空结构，上横杆22可以设置有开口端83，上横杆22的两个侧面诸如上侧面和下侧面可以设置有凹槽87；

下动力驱动装置可以与上动力驱动装置2结构相同，且上横杆22可以替换为下横杆62， 上滑块21可以替换为下滑块61。
