The invention belongs to the technical field of aircraft cabin door maintenance, and particularly relates to an aircraft maintenance cabin door folding and unfolding mechanism which comprises a base and a lifting table fixedly connected to the upper surface of the base, a plurality of supporting columns are slidably connected to the upper surface of the lifting table, and supporting frames are integrally formed on the upper surfaces of the supporting columns. A plurality of fixed mounting blocks are integrally formed on the outer surface of the lifting table, lead screws are connected to the interiors of the fixed mounting blocks in a screwed mode, and the lifting table is fixedly connected to the upper surface of the base, so that the lifting table conveniently drives supporting columns on the upper surface of the lifting table to conduct lifting operation. Meanwhile, the fixed mounting blocks are arranged on the outer surface of the lifting table, the lead screws screwed in the fixedmounting blocks can conveniently drive the supporting columns to move on the upper surface of the lifting table, so that the supporting frames on the upper surfaces of the supporting columns can conveniently clamp an aircraft cabin door, then the aircraft cabin door is driven by the lifting table to slowly descend, and thus the aircraft cabin door is safer during descending maintenance.

    本发明属于飞机舱门维修技术领域,尤其为一种飞机维修舱门的收放机构,包括底座,以及固定连接在底座上表面的升降台,所述升降台的上表面滑动连接有若干个支撑柱,所述支撑柱的上表面一体成型有支撑架,所述升降台的外表面一体成型有若干个固定安装块,所述固定安装块的内部旋合连接有丝杠,在底座的上表面固定连接有升降台,使得升降台便于带动其上表面的支撑柱进行升降作业,同时在升降台的外表面设置有固定安装块,使得旋合在固定安装块内部的丝杠便于带动支撑柱在升降台的上表面进行移动,从而使得支撑柱上表面的支撑架便于对飞机舱门进行夹持,然后再通过升降台带动飞机舱门进行缓慢下降,从而使得飞机的舱门在下降维修时更加的安全。
