The invention relates to a dragging type boarding lifting system. The system comprises a foldable sliding rail, a lifting platform, a driving device and a control unit, the foldable sliding rail is arranged between a passenger cabin door of an airplane and the ground during boarding, the lifting platform is configured to slide along the foldable sliding rail, and the driving device is used for driving the lifting platform and comprises a winch and a driving motor. The driving device further comprises a laser range finder and a capstan angle encoder, and the control unit receives position data measured by the laser range finder and capstan angle data measured by the capstan angle encoder and calculates the instantaneous speed and the instantaneous acceleration of the lifting platform. Therefore, the speed and/or the acceleration of the lifting platform are/is controlled within a rated value range by controlling the current of the driving motor. According to the technical scheme, the system has the following beneficial technical effects that the impact problem of starting and stopping of the lifting platform is solved, and therefore the comfort of a prone patient in the process of using the system is improved.

    本发明涉及拖拽式登机升降系统。该系统包括可折叠滑轨、升降平台、驱动装置、以及控制单元,可折叠滑轨在登机时设置在飞机客舱门与地面之间,升降平台构造成能沿着可折叠滑轨滑动,驱动装置用于驱动升降平台,驱动装置包括绞盘和驱动电机,驱动装置还包括激光测距仪和绞盘角度编码器,控制单元接收激光测距仪测出的位置数据和绞盘角度编码器测出的绞盘角度数据,计算出升降平台的瞬时速度和瞬时加速度,从而通过控制驱动电机的电流来实现将升降平台的速度和/或加速度控制在额定数值范围内。根据上述技术方案,本发明能起到以下有益技术效果:改善了升降平台启动与停止的冲击问题,从而提高了卧姿病员在使用本系统过程中的舒适性。
