Combined cargo bridge for military aviation cargo handling

Abstract

The invention relates to a combined cargo bridge for military aviation cargo handling. The combined cargo bridge comprises a plurality of supporting frames. After the supporting frames are connected together, an inclined structure is formed. One end of the upper surface of the inclined structure is close to the ground, and the height of the other end of the inclined structure is consistent with the height of a bottom plate of an airplane cargo hatch. Small wheels are arranged on the lower portion of the rear side face of the supporting frame. The bottoms of the small wheels are higher than the bottom faces of the supporting frame. A hoisting device is arranged on the lower rear portion of the supporting frame. Auxiliary wheels capable of ascending and descending are arranged on the two sides of the lifting device. The auxiliary wheels are hinged to the supporting frame through a connecting frame so as to achieve ascending and descending. A locking device is arranged on the connecting frame. A lifting device is arranged on the upper portion of a main supporting frame in contact connection with a bottom plate of an airplane cargo compartment. The combined cargo bridge has the advantages of being convenient and quick to move without any power source, being adjustment in height and being suitable for airplanes of different specifications.

Description

technical field [0001] The invention relates to the technical field of cargo loading and unloading in air transportation, in particular to a military air cargo loading and unloading combined cargo bridge. Background technique [0002] The loading and unloading of cargo is an important link in air transportation, especially in wartime, whether the air handling device can be quickly put in place, and whether it can be used with military transport aircraft with different cargo hatch heights are very important requirements for it. There are two main types of devices for loading and unloading cargo in traditional air transport: one is a transport platform vehicle with a liftable platform, and the other is a loading and unloading platform with an inclined upper surface. The transportation platform vehicle is flexible, but the load capacity is limited. When moving, it needs a power source, and it needs to be loaded and unloaded by manpower.

AI Technical Summary

Problems solved by technology

The transportation platform vehicle is flexible, but the load capacity is limited. When moving, it needs a power source, and it needs to be loaded and unloaded by manpower. A lot of time is spent on loading and unloading goods. The number of times of handling is large, and there are many intermediate links. It is easy to cause damage and loss of materials, which greatly prolongs the The retention time of the aircraft has seriously affected the rapid response ability of the military logistics, and the requirements for the operators of the lifting platform are high, it is difficult to dock with the aircraft, it is easy to damage the aircraft, and it is impossible to load and unload oversized and overweight items

The loading and unloading platform is also called the loading and unloading bridge. Since multiple support frames are connected and combined to form a platform with an inclined upper surface, transmission devices such as conveyor rollers or conveyor chains are set on the upper surface of the platform for cargo transmission. The defects of the loading and unloading platform are: inconvenient Mobile, unable to be quickly put in place, unable to meet the requirements of rapid transfer, and unable to adapt to the use of aircraft cargo compartments of different heights. Aircraft of different specifications and models must be equipped with cargo bridges of different heights and sizes, which is costly and occupies a large area

A small number of loading and unloading platforms are equipped with lifting devices at the bottom. After lifting, the center of gravity is prone to instability and poor stability. It is not suitable for loading and unloading large batches and heavy goods.
