The invention discloses an ARJ21 aircraft tail cabin approaching platform. The ARJ21 aircraft tail cabin approaching platform comprises a base, an extension ladder, at least one lifting stand column and a working platform, wherein the extension ladder and the fixed end of the lifting stand column are perpendicularly and fixedly connected to the base, the working platform is fixedly installed at the end of the lifting end of the lifting stand column, the extension ladder is arranged on one side of the working platform, the upper end of a telescopic ladder section in the telescopic ladder is fixedly connected with the bottom of the working platform, a hydraulic cylinder is connected between the working platform and the base and fixedly connected to the base, and a telescopic rod of the hydraulic cylinder is connected with the working platform and used for driving the working platform to ascend and descend. Compared with an existing method for erecting a wooden frame in a tail cabin, the time for erecting the wooden frame and dismantling the wooden frame is saved, the maintenance efficiency is effectively improved, meanwhile, the risk that residual materials are left in the tail cabin is reduced, the device does not need to make contact with the structure in the tail cabin, and damage to the structure in the tail cabin is avoided.

    本发明公开了一种ARJ21飞机尾舱接近平台,包括底座、伸缩梯、至少一条升降立柱和工作平台,伸缩梯和升降立柱固定端垂直固定连接在底座上,工作平台固定安装在升降立柱的升降端端部上,伸缩梯设置于工作平台的一侧,且伸缩梯中的伸缩梯段的上端与工作平台的底部固定连接,在工作平台与底座之间连接有液压缸,液压缸固定连接在底座上,液压缸的伸缩杆与工作平台连接,用于驱动工作平台升降。本发明与现有的在尾舱内部搭木架的方法相比,节省了搭木架及拆除木架的时间,有效提高维修效率,同时降低了有残余材料遗留在尾舱内部的风险,并且本发明无需与尾舱内部的结构进行接触,避免了对尾舱内部的结构造成损伤。
