为对移动放射源或探测器进行移动刻度,模拟车载探测器的移动测量,研制了移动刻度轨道及配套台架。根据移动刻度需求及试验大厅布局进行了轨道机械结构、电气功能设计,经过安装调试,建立了移动刻度试验大厅。测试结果表明,移动刻度轨道配合台架能满足常规移动刻度测量需求。如图1所示,移动放射源或探测器安装于移动安装板上,由伺服电机带动皮带牵拉移动件在直线光轴上滑动。伺服电机由PLC控制,运动方式为先加速到设定速度,后匀速运动,通过指定匀
In order to move the mobile radio source or detector scale, the movement of the vehicle detector is simulated and the mobile scale track and the supporting platform are developed. According to the requirements of mobile scale and the layout of the test hall, the orbital mechanical structure and electrical function design were carried out. After installation and commissioning, a mobile scale test hall was established. The test results show that the mobile scale rail with the bench to meet the needs of conventional mobile scale measurement. As shown in FIG. 1, a mobile radioactive source or detector is mounted on a movable mounting plate, and the servomotor drives the belt to pull the sliding member to slide on the linear optical axis. Servo motor controlled by PLC, the movement mode is to accelerate to the set speed, after uniform movement, through the designated uniform
