Problems solved by technology
At present, the commonly used carriages or bombs use lever or link mechanism, which cannot meet the requirements of stability, speed and precision. It is often necessary to adjust the position and posture to align the hole position. Sometimes the adjustment of the linear position is required, and sometimes even the Angle and attitude adjustment, this adjustment process sometimes takes a long time

The invention belongs to the technical field of comprehensive support equipment of aircrafts, and particularly relates to a lifting device for quickly hanging an external store of an airplane. Comprising a fixed supporting frame (21) and a movable supporting frame (22), the fixed supporting frame (21) comprises an outer cylinder (211), a bottom plate (212) is arranged at the bottom end of the outer cylinder (211), a guide groove (213) is formed in the inner wall of the outer cylinder (211), a vertically-arranged stud (214) is fixed to the center of the bottom plate (212), the movable supporting frame (22) is provided with an inner cylinder (221), a lifting plate (222) is arranged at the bottom end of the inner cylinder (221), and an upper end plate (223) is arranged at the top end of the inner cylinder (221). The outer wall of the inner cylinder body (221) is provided with a guide column (224) matched with the guide groove (213). The servo motor is adopted to drive the gear boss to move up and down along the stud on the fixed supporting frame, the movable supporting frame is driven to ascend and descend, so that the height of an external store is conveniently adjusted, enough bearing capacity is achieved, the height ascending and descending process is rapid and accurate, and the posture is stable.
Description
technical field [0001] The application belongs to the technical field of aircraft comprehensive support equipment, and in particular relates to a lifting device used for the quick hanging of aircraft external objects. Background technique [0002] Military aircraft carrying out combat missions must carry external weapons, and support personnel often need to complete the installation or replacement of weapons. Especially in wartime, the speed of weapon installation (the time to complete the replacement) directly affects the efficiency of fighter jets. When hanging or changing external weapons, it is often necessary to adjust the height of the external objects. During the process of raising and lowering the height, the posture should be kept stable, fast and precise, and there must be sufficient carrying capacity. At present, the commonly used carriages or trailers use levers or linkages, which cannot meet the requirements of stability, speed and precision. It is often necessa...
