Description

Aircraft jacking vehicle

Technical Field

The utility model relates to an aircraft jacking car.

Background

When an aircraft fails and needs to be repaired, the aircraft is required to be lifted up in many cases to facilitate the modification of the relevant repaired components, such as the repair and replacement of landing gear. Aircraft jacking points, which are typically specified in the aircraft manufacturer's maintenance manual, determine whether the aircraft will be balanced during jacking and the load that each jacking point can withstand. Generally, at least 3 jacking points are needed for jacking an airplane, main jacking points are located on left and right wings, and the jacking points at the nose or near the tail are smaller. Some aircraft may employ four auxiliary jacking points to increase fuselage stability.

At present, a large triangular steel frame jack is adopted for jacking. In the jacking process, the jack pad can ensure the position preparation of the jacking point, prevent the end part of a jack rod from sliding off from the jacking point, disperse the stress area, protect the body structure, and the jacking point of most airplanes is also provided with the jack pad. The airplane needs to leave the site with irrelevant personnel and ground equipment in the jacking process, and the airplane needs to be slowly and synchronously jacked and put down, so that the horizontal quantity does not exceed the safety limit. This kind of jack mode of adopting the steelframe, equipment structure is simple, but bulky, and weight is heavy, need place and adjusting position through the manual work, and altitude mixture control volume is limited, often needs to fill up the high space requirement that the support could reach the jacking in the lower part, and the stress of unable monitoring jack has increased the impaired uncontrollable risk of fuselage moreover.

At present, jacking is carried out by adopting a mode similar to the way of listing a 'mattress', each layer of the 'mattress' is 10-20 cm thick, the interior of the 'mattress' can be inflated, a plurality of layers of the 'mattress' are listed, and then the 'mattress' is inflated, and the height and the jacking force are adjusted through air pressure. If the 'mattress' is too many layers when in use, once the load is unbalanced, the 'mattress' can incline, the stability of the jacking force can not be ensured, the arrangement of the air charging and discharging pipelines is more due to the 'mattress' of the multiple layers, the height and the pressure of each layer of 'mattress' controlled by the valve group are difficult to control, the synchronism is poor, computer software needs to be introduced to control the pipelines sometimes, and the set of jacking system is very high in price and limited in use occasions. Meanwhile, the material of the mattress is high molecular material, so that the aging period is certain, and the service life and the times are influenced. In addition, the auxiliary hoisting is carried out by adopting a truck crane, the mode is only an emergency mode, the jacking and maintenance operation can not be carried out for a long time, and the application that the truck crane completely hoists the whole airplane is not seen.
