Embodiment 1

[0047] 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 connecting flange is square, and the connecting rods are integrally made in the middle of the four sides, and the adjacent connecting rods in the vertical direction are fixed by pin shafts .

[0048] 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. There are 11 airbag layers from the bottom layer to the top layer. The four airbags in each airbag layer form a group. Each group controls the air pressure as a unit. Corresponding pipelines, valves, and air pumps need to be equipped outside the airbags in each unit. Barometer and other related inflatable components. The rated air pressure of the jacking system is 1MPa, the initial height is 2m, the maximum jacking height is 6.5...

Abstract

The invention belongs to the field of aircraft rescue, and relates to jacking equipment for aircrafts, in particular to a jacking system for an aircraft and a jacking method. An oil cylinder is included, an adapter is installed at the lifting end of the oil cylinder, the oil cylinder can control the adapter to move up and down, a jacking device is installed below the oil cylinder, and the jacking device is used for enabling the oil cylinder and the adapter to move up and down synchronously and adjusting the axis angle of the adapter in the horizontal direction. The lower end portion of the oil cylinder is installed in an installation base, a plurality of lug plates are evenly installed outside the installation base at intervals, and the end portions, away from the installation base, of the lug plates are fixedly installed on the jacking device. The jacking device comprises a height adjusting assembly and an angle adjusting assembly, the height adjusting assembly is used for adjusting the horizontal height of the oil cylinder, and the angle adjusting assembly is used for adjusting the angle of the adapter in the horizontal direction.

Description

technical field [0001] The invention belongs to the field of aircraft rescue, and relates to an aircraft jacking device, in particular to an aircraft jacking system and a jacking method. 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 field of aircraft rescue 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 to increase its jacking stroke. Its actual...
