The invention belongs to the technical field of nuclear power maintenance, and particularly relates to a lifting transmission mechanism for nuclear reactor pressure vessel inspection. According to thelifting transmission mechanism, each winch assembly and a scanning support are subjected to one-time fixed pulley reversing, and the scanning support can be dragged to move in the vertical direction.A first displacement detection assembly can detect the moving distance of a first traction rope driven by the first winch assembly, a second displacement detection assembly can detect the moving distance of a second traction rope driven by the second winch assembly, therefore, the position of the scanning support in the vertical direction can be adjusted through the first winch assembly or the second winch assembly according to the difference value between data detected by the first displacement detection assembly and data detected by he second displacement detection assembly, therefore, thehorizontal position of the scanning support is accurately and finely adjusted, it is ensured that a scanner on the scanning support is in a horizontal state, the scanner is effectively conveyed, and the position of the scanner is accurately positioned.

    本公开属于核电维修技术领域,具体涉及一种用于核反应堆压力容器检查的升降传动机构。本公开中,每个卷扬组件与扫查支架间经过一次定滑轮换向,可以牵引扫查支架在竖直方向运动,第一位移检测组件可以检测第一卷扬组件带动第一牵引绳移动的距离;第二位移检测组件可以检测第二卷扬组件带动第二牵引绳移动的距离,这样,可以根据第一位移检测组件所检测到的数据和第二位移检测组件所检测到的数据之间的差值,通过第一卷扬组件或第二卷扬组件来调整扫查支架在竖直方向的位置,从而对扫查支架的水平位置进行精确微调,由此确保扫查支架上的扫查器处于水平状态,从而有效运送扫查器,并对扫查器的位置进行准确定位。
