The invention belongs to the technical field of aircraft rescuing equipment, and particularly relates to a pulley assembly and an adjustable type secondary beam structure comprising same. The pulley assembly comprises a fixed pulley unit and an adjustable pulley unit, wherein the fixed pulley unit and the adjustable pulley unit are detachably connected together; the fixed pulley unit comprises a mounting frame I and two fixed pulleys which are rotatably and coaxially mounted in the mounting frame I; the adjustable pulley unit comprises a mounting frame II, a movable pulley which is rotatably mounted in the mounting frame II, and a hanger fixedly connected to the lower end of the mounting frame II; the adjustable type secondary beam structure comprises a secondary hanging and the pulley assembly; at least one group of pulley assemblies is arranged, and the pulley assembly further comprises a steel wire rope which sequentially passes through each pulley assembly, and the pulley assemblycan be separately connected to the lower end of the secondary hanging beam in a sliding mode. The pulley assembly can solve the problem that an existing airplane hanging rope is relatively great in limitation, and operation of replacing the model of an aircraft is convenient.
本发明属于航空器救援设备技术领域,尤其是涉及一种滑轮组件及包含其的可调节式副梁结构;滑轮组件,包括固定滑轮单元和可调滑轮单元;固定滑轮单元和可调滑轮单元可拆卸连接在一起的;固定滑轮单元包括一号安装架以及可转动且同轴安装在一号安装架中的两个定滑轮,可调滑轮单元包括二号安装架、可转动安装在二号安装架中的动滑轮、以及固接在二号安装架下端的吊钩;可调节式副梁结构,包括副吊梁以及如上的滑轮组件,其中,滑轮组件设有至少一组,还包括依次穿过各个滑轮组件的钢丝绳;滑轮组件可分别滑动连接在副吊梁下端。本发明可以解决目前的飞机吊装索具局限性比较大,以及更换航空器的机型时操作不便的问题。
