The invention relates to the field of airport ground equipment, in particular to a wide-range passenger ladder telescopic structure ladder body which comprises a fixed ladder, a telescopic ladder and a ladder telescopic oil cylinder and further comprises a telescopic assembly. The telescopic assembly comprises a telescopic tail ladder, a pedal mounting frame, a bottom support and an elastic component, the pedal mounting frame is slidably connected with the telescopic ladder through the elastic component, the bottom support is fixedly connected with the fixed ladder, and the telescopic tail ladder is fixedly connected with the pedal mounting frame; at the moment, the pedal mounting frame and the telescopic tail ladder are limited and lifted by the bottom support, the steps of the telescopic tail ladder are compressed to be next to the lower surface of the lowermost fixed step of the telescopic ladder, and at the moment, the elastic component is stretched and stores energy; the telescopic tail ladder is pushed out under the action of gravity and the elastic component until reaching a limiting position, and reaches the same height difference and depth position as other fixed steps.
本发明涉及机场地面设备领域,具体涉及一种宽范围客梯车伸缩结构梯身,包括固定梯、伸缩梯和阶梯伸缩油缸,还包括伸缩组件;伸缩组件包括伸缩尾梯、踏板安装架、底托和弹性构件,踏板安装架通过弹性构件与伸缩梯滑动连接,底托与固定梯固定连接,伸缩尾梯与踏板安装架固定连接,当伸缩梯降到最低时,伸缩梯带动踏板安装架抵接底托,此时踏板安装架和伸缩尾梯被底托限位和托举,伸缩尾梯的踏步被压缩紧挨着在伸缩梯最下一级固定踏步下面,此时弹性构件被拉伸并蓄能,当伸缩梯被阶梯伸缩油缸推出,和固定梯产生直线位移时,伸缩尾梯受重力和弹性构件的作用被推出,直到限位位置,达到和其它固定踏步一样的高差和深度位置。
