The invention particularly relates to an aircraft cargo bridge which comprises a cargo bridge body, an auxiliary cargo bridge, a limiting beam, a driving rocker arm, an ox horn rocker arm and a transmission rod system. The front end of the cargo bridge body is hinged to a cargo hold structure. The front end of the auxiliary cargo bridge is hinged to the tail end of the cargo bridge body. The front end of the driving rocker arm is hinged to a cargo hold structure; the root of the ox horn rocker arm is hinged to the tail end of the cargo bridge body, and the tail end is clamped in the sliding groove; the front end of the transmission rod system is hinged to the rear end of the driving rocker arm, and the rear end of the transmission rod system is hinged to the ox horn rocker arm; when the cargo bridge body is put down, the driving rocker arm rotates, the oxhorn rocker arm can be driven to rotate through the transmission rod system, the tail end of the oxhorn rocker arm slides in the sliding groove, and therefore the auxiliary cargo bridge is driven to rotate, and the auxiliary cargo bridge is put down synchronously and makes contact with the ground. When the cargo bridge body is folded, the driving rocker arm rotates, the oxhorn rocker arm can be driven to rotate through the transmission rod system, the tail end of the oxhorn rocker arm slides in the sliding groove, and therefore the auxiliary cargo bridge is driven to rotate and synchronously folded.

    本申请具体涉及一种飞机货桥,包括货桥主体、辅助货桥、限动梁、驱动摇臂、牛角摇臂、传动杆系;货桥主体前端铰接在货舱结构上;辅助货桥前端铰接在货桥主体末端,前端底部具有滑槽;驱动摇臂前端铰接在货舱结构上;牛角摇臂根部铰接在货桥主体末端,末端卡在滑槽中;传动杆系设置在货桥主体上,前端与驱动摇臂后端铰接,后端铰接在牛角摇臂上;货桥主体放下时,驱动摇臂转动,能够通过传动杆系带动牛角摇臂转动,使牛角摇臂末端在滑槽中滑动,从而带动辅助货桥转动,使辅助货桥同步放下,与地面接触;货桥主体收起时,驱动摇臂转动,能够通过传动杆系带动牛角摇臂转动,使牛角摇臂末端在滑槽中滑动,从而带动辅助货桥转动,使辅助货桥同步收起。
