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.
