Description

Technical Field

[0001] The invention relates to the technical field of aircraft fairing assembly and disassembly, in particular to a suspension device used for aircraft fairing assembly and disassembly. Background Art

[0002] The suspension device for installing and removing aircraft fairings is an engineering equipment specially used in aircraft maintenance and repair scenarios. It is mainly used to safely and efficiently remove and install aircraft fairings. As an important aerodynamic component of the aircraft, the fairing is usually covered on the outside of the engine, landing gear or other key structures, playing the role of reducing air resistance, protecting internal components and optimizing fluid mechanics performance. Due to its large size, heavy weight and high altitude or limited space installation location, manual handling is extremely risky. The suspension device solves the problems of low efficiency and many safety hazards in traditional operations through mechanical assistance. It is an indispensable professional tool in the modern aviation maintenance system. The patent with announcement number CN222742917U discloses a suspension device for assembling and disassembling aircraft fairings, including a suspension mechanism, a top snap-fit ​​mechanism, a three-point support mechanism and two bottom snap-fit ​​mechanisms; the top snap-fit ​​mechanism and the two bottom snap-fit ​​mechanisms are respectively installed on the three support ends of the three-point support mechanism, the top snap-fit ​​mechanism is used to snap-fit ​​at the arc top position of the fairing, and the two bottom snap-fit ​​mechanisms are used to snap-fit ​​at the two lower edges of the fairing; the suspension mechanism is connected to the top snap-fit ​​mechanism for connecting to the movable bracket. The three-point support mechanism can be used to support the top snap mechanism and the two bottom snap mechanisms, so that the top snap mechanism and the two bottom snap mechanisms can respectively stably support the arc top position and the two lower edges of the fairing, ensuring that the overall structure of the fairing is not deformed during lifting. However, when the suspension device is in use, it can usually only suspend and lift the aircraft fairing to a specific height in the vertical direction, and the degree of automation is low. At the same time, the aircraft fairing is prone to arbitrary swinging during the suspension process, which reduces the suspension safety.
