Problems solved by technology

[0003] Existing jacks are usually hydraulic jacks. The weight range supported by traditional aircraft fuselage jacks is limited, and it cannot adapt to the weight of most aircraft fuselages, and cannot realize the fit and lift support of the aircraft fuselage. Therefore, a general-purpose jack is proposed. aircraft fuselage jack

Abstract

The invention relates to the field of aircraft maintenance equipment, in particular to a universal aircraft fuselage jack, which comprises a supporting mounting plate, a lifting mounting plate arranged on one side of the supporting mounting plate in an opposite mode and an adjusting lifting mechanism arranged between the supporting mounting plate and the lifting mounting plate; a combined lifting supporting module is arranged on one side of the lifting mounting plate; and the combined lifting supporting module comprises a combined hydraulic lifting mechanism and an adaptive supporting mechanism, the combined hydraulic lifting mechanism is mounted on the lifting mounting plate, the adaptive supporting mechanism is matched with the combined hydraulic lifting mechanism, and the initial height is adjusted by adjusting the lifting mechanism, so that the lifting supporting module can conduct supporting and jacking operation more quickly, it is guaranteed that the jacking operation has the enough length range, the supporting mechanism is adapted to be lifted through the combined hydraulic lifting mechanism, the supporting mechanism makes contact with an aircraft fuselage to conduct lifting operation, and attached lifting supporting at different supporting positions can be adapted, and meanwhile, the supporting and jacking force can be adaptively adjusted.

Description

technical field [0001] The invention relates to the field of aircraft maintenance equipment, in particular to a general-purpose aircraft fuselage jack. Background technique [0002] A jack is a tool used to elevate heavy objects and is widely used in fields such as construction, automobiles, railways and aviation. In the field of aviation, it is necessary to automatically adjust the attitude of the aircraft during ground tests such as aircraft weight and center of gravity measurement. At this time, a special jack device is required, and the jack device is also required when the aircraft is maintained and replaced. [0003] Existing jacks are usually hydraulic jacks. The weight range supported by traditional aircraft fuselage jacks is limited, and it cannot adapt to the weight of most aircraft fuselages, and cannot realize the fit and lift support of the aircraft fuselage. Therefore, a general-purpose jack is proposed. type aircraft fuselage jack. Contents of the invention...
