The invention belongs to the technical field of cabin door locking mechanism design, and particularly relates to an aircraft auxiliary cargo bridge folding limiting and locking device. Comprising a mounting support which is fixedly mounted on a machine body structure, and a support connecting part is arranged on the mounting support; the limiting rocker arm comprises a supporting rod section and a grabbing hook section which are integrally formed, a first connecting part is arranged at the end part of the supporting rod section and is connected with a support connecting part on the mounting support through a hinge bolt and a torsional spring, a second connecting part is arranged at the end part of the grabbing hook section, and a roller is mounted on the second connecting part; a limiting part is further arranged at the end of the supporting rod section, and under the action of the torsional spring, the limiting rocker arm rotates clockwise till the limiting part is matched with the machine body structure to achieve limiting. The auxiliary cargo bridge has one-way self-adaption and movement limiting locking functions, can adapt to different movement states of folding of the auxiliary cargo bridge, can effectively lock the auxiliary cargo bridge at the folding and closing position, and can prevent the auxiliary cargo bridge from generating unsafe incidents under the action of inertial load and the like in the using process of an airplane.
本申请属于舱门锁定机构设计技术领域,特别涉及一种飞机辅助货桥收起限动锁定装置。包括:安装支座固定安装在机体结构上,安装支座上设置有支座连接部;限动摇臂包括一体成型的支杆段以及抓钩段,支杆段的端部设置有第一连接部,第一连接部通过铰链螺栓以及扭簧与安装支座上的支座连接部连接,抓钩段的端部设置有第二连接部,第二连接部安装有滚轮;支杆段的端部还设置有限位部,在扭簧的作用下,限动摇臂沿顺时针转动,直至限位部与机体结构配合实现限位。本申请具有单向自适应以及限动锁定功能,可以适应辅助货桥收起不同的运动状态,能够有效将辅助货桥锁定在收起关闭位置,飞机使用过程中,能够防止其在惯性载荷等作用下发生不安全事件。
