The invention provides a multifunctional ladder bed for airplane maintenance. The multifunctional ladder bed for airplane maintenance comprises a base, a primary ladder bed, a secondary ladder bed anda steering ladder bed. The primary ladder bed is hinged to the tail portion of the base, a telescopic cylinder is arranged on the rear portion in the base, and a lifting device is arranged on the primary ladder bed. The secondary ladder bed is mounted in a first sliding groove of the primary ladder bed, and a steering device is arranged on the top of the secondary ladder bed. The steering devicecomprises two steering mounting seats fixedly arranged on the top of the secondary ladder bed correspondingly. Mounting holes are formed in the steering mounting seats, a second rotary shaft is rotationally mounted in the mounting holes, a second gear and a second hand wheel are arranged at the two ends of the second rotary shaft correspondingly, two ladder bed inserting holes are further formed in the second rotary shaft, and the steering ladder bed can be inserted into the ladder bed inserting holes and fastened. According to the multifunctional ladder bed, the inclination angle of the primary ladder bed can be adjusted through the telescopic cylinder, the lifting height of the secondary ladder bed can be adjusted through the lifting device, the deflection angle of the steering ladder bed can be adjusted through the steering device, multiple portions have adjusting functions, and the applicability is high.

一种飞机维修用的多功能梯架，包括底座、一级梯架、二级梯架及转向梯架。一级梯架铰接在底座尾部，底座中后部设置有伸缩缸，一级梯架上设置有升降装置；二级梯架安装在一级梯架的第一滑槽内，二级梯架的顶部设置有转向装置。转向装置包括分别固定设置在二级梯架顶部的两块转向安装座，该转向安装座上开设有安装孔，安装孔内转动安装有第二转轴，该第二转轴的两端分别设置有第二齿轮和第二手轮，第二转轴上还设置有两个梯架插孔，转向梯架可插入该梯架插孔并固紧。本多功能梯架可通过伸缩缸来调整一级梯架的倾斜角度、通过升降装置来调整二级梯架的升降高度、通过转向装置来调整转向梯架的偏转角度，多部位均具有调节功能，适用性强。
