Embodiment 1

[0036] In practical application, the jacking system adopts a design structure of 2 rows, 2 columns, and 12 layers with 48 spherical airbags in total. The 12 vertical spherical airbags are equipped with 12 connecting flanges, each of which is circular or quasi-circular, and the four directions of the outer circumference are uniformly spaced and fixed with the connecting rods. Adjacent connecting rods are fixed by means of bearing pins.

[0037] The four airbags on the bottom layer are arranged in groups of two, and each group acts as a unit to control the air pressure. The 11 airbag layers from the second bottom layer to the top layer, the four airbags in each airbag layer form a group, and each group controls the air pressure as a unit. The rated air pressure of the jacking system is 1MPa, the initial test height is 2m, the maximum jacking height is 6.5m, the maximum allowable axis offset angle is 7°, the rated load is 160t, and the floor area is 3.4m×3.4m.

Abstract

The invention belongs to the field of aviation rescue, and relates to jacking equipment for aircrafts, in particular to an axis angle adjustable jacking device for an aircraft and an assembling method of the axis angle adjustable jacking device. The axis angle adjustable jacking device comprises a height adjusting assembly and an angle adjusting assembly, the height adjusting assembly is used for adjusting the horizontal height, and the angle adjusting assembly is used for adjusting the swing angle of a connecting line from bottom to top relative to the horizontal plane; the height adjusting assembly and the angle adjusting assembly both are air bags, the multiple air bags are stacked in the longitudinal direction, the air bag located on the bottom layer is the angle adjusting assembly, and the multiple air bags located on the bottom layer are the height adjusting assembly. The connecting lines of the plurality of air bags from the bottom to the top are positioned in the same straight line; the air bags are arranged in groups, each group comprises a plurality of air bags which are distributed in rows and columns, and the air bags in the same group are uniformly spaced to form air bag layers respectively; and the number of the air bags in each air bag layer from bottom to top is consistent.

Description

technical field [0001] The invention belongs to the field of aviation rescue, and relates to a jacking device for an aircraft, in particular to a jacking device for an aircraft with an adjustable axis angle and an assembly method thereof. Background technique [0002] The jack is a lifting device based on a rigid lifting piece, and its use is widely used in various fields. Taking its implementation in the aircraft field as an example, it can be applied to multiple work processes such as aircraft repair, maintenance, and equipment replacement. [0003] At present, the jacking equipment used for aircraft mostly adopts the traditional column type hydraulic jack, and its structure mainly includes an oil cylinder and an adapter adapted to the aircraft type. This type of jack is small in size and has a large load, so it can be widely used in most models. In actual use, due to the limited adjustable stroke of the jack, it is generally necessary to configure a corresponding base t...
