Method for integrally jacking airplane

Abstract

The invention discloses a method for integrally jacking an airplane. The method comprises the steps that S1, the airplane is adjusted to be horizontal; S2, a tractor is used for dragging a plurality of jacks to the position, below corresponding top nests, of the airplane, and the centers of the top nests are positioned through a light beam emitter; S3, the jacks are adjusted to be horizontal, andthe positions of the jacks are finely adjusted to enable light beams emitted by the light beam emitter to vertically irradiate the centers of the corresponding top nests; S4, a power switch of each jack is turned on through an automatic control program, so that lifting cylinders of the jacks synchronously ascend, the airplane is lifted to the required target height, safety nuts on the lifting cylinders are driven to rotate through a motor while the lifting cylinders of the jacks ascend, and thus a constant distance is kept between the safety nuts and the outer cylinders of the jacks; and S5, the lifting cylinders of the jacks are synchronously descended until the jacks are separated from the top nests of the airplane after the airplane is maintained and detected, and the airplane is put down. The airplane jacking efficiency can be improved, and the labor intensity can be reduced.

Description

technical field [0001] The invention relates to the technical field of aircraft maintenance, in particular to an overall jacking method for an aircraft. Background technique [0002] When carrying out aircraft overhaul work such as deep maintenance of aircraft landing gear, the entire aircraft needs to be lifted, and the lifted aircraft will be lowered after the maintenance work is completed. The aircraft has a special top nest, such as figure 1 For the A330 aircraft in the aircraft coordinate system, the first jacking hole 1 and the third jacking hole 3 are set on the left and right in the X direction of the aircraft coordinate system, and the second jacking hole 2 is set in the Y direction. Position to jack up the aircraft. [0003] According to the requirements of technical manuals such as aircraft maintenance manuals, a level or plumb bob is usually set inside the aircraft, and professional technicians observe the level of the aircraft inside the aircraft, and report t...

AI Technical Summary

Problems solved by technology

[0011] 1. Many people are needed. The adjustment of the power switch of each jack and the adjustment of the safety nut require professional operation. Professionals must also continuously observe the horizontal attitude of the aircraft inside the aircraft. In addition, other auxiliary personnel are required. The staff required for lifting and lowering work is generally more than 8 people

[0012] 2. The manual labor intensity is high. First, the jack used for lifting the aircraft is heavy and difficult to move. Second, it requires the staff to continuously control the attitude of the aircraft for a long time and ensure the safety during the jacking process.

[0013] 3. The efficiency is low. Generally, it is necessary to adjust the position of the jack several times to make it accurately align with the aircraft nest, and repeatedly fine-tune the jack to its own level.

During the process of lifting and lowering the aircraft, the staff inside and outside the aircraft must talk to each other to determine the size of the power switch of each jack, which requires the staff to have rich experience. These human factors will lead to very low work efficiency.
