Background
A jack is a jacking apparatus based on a rigid jacking member, and is widely used in various fields. Taking the implementation mode of the method in the field of aircrafts as an example, the method can be applied to a plurality of working processes such as aircraft maintenance, maintenance and equipment replacement.
At present, jacking equipment for aircrafts mostly adopts a traditional column type hydraulic jack, and the structure of the jack mainly comprises an oil cylinder and an adapter matched with a machine type. The jack has small volume and large load and can be widely applied to most machine types. In the practical use process, because the adjustable stroke of the jack is limited, a corresponding base is generally required to be configured to increase the jacking stroke of the jack. The practical use of the device is shown in patent numbers 201201945103, 2017204340641 and 2015105243625.

However, the jacking devices with the above structures all have certain problems. Firstly, the height adjustment in the vertical direction is not flexible enough, and the maximum height of each base in the unfolding state limits the jacking height limit of the jacking device because the height of each base is limited. Because the model of each aircraft is different, the interval between its jacking position and the ground is unset, and the high limit of the base that the above-mentioned patent disclosed all is fixed, can not carry out extensive adjustment, when the interval between aircraft and the ground is too high or low, this type jacking device all can't normal use. Secondly, the structure of the jacking device has high requirements on the ground at the jacking position, namely the triangular structure at the bottom of the base is basically in a horizontal state to be normally used. If the ground is soft basic planes such as soil, grassland and the like, the bottom of the jacking device is not fixed stably enough, and great dumping risk exists. Thirdly, the jacking angle of the hydraulic cylinder of the jacking device with the structure can not be adjusted, and the hydraulic cylinder can only be displaced in the vertical direction. Because the jacking device is arranged below the jacking position of the aircraft, the horizontal position of the hydraulic cylinder cannot be ensured to be just below the orthographic projection position of the jacking position when the jacking device is at the low position. When jacking device expanded to high-order position, then there was the condition of deviation in the pneumatic cylinder and the aircraft jacking position likely to appear, at this moment, can only transfer jacking device to low level position again, then wholly with its whole translation jacking once more. The operation of the process is high in requirement and difficulty, and the process may need to be repeatedly adjusted for several times.
