Description

Technical Field

[0001] The invention belongs to the technical field of loading and unloading transportation, and in particular relates to a loading and unloading transportation platform used for loading and unloading an airdrop cargo platform. Background Art

[0002] At present, our military's large transport aircraft, such as the Y-20, Il-76, Y-8, and Y-9, mainly use aviation cargo pallets and auxiliary cargo bridges with slide rails to load and unload non-self-propelled equipment. By towing the cargo pallets to slide on the auxiliary cargo bridge, efficient loading and unloading of non-self-propelled equipment can be achieved. When facing the new airdrop cargo platform, the traditional loading and unloading method has the following shortcomings:

[0003] 1. The gauge of the slide rail on the auxiliary cargo bridge does not match the position of the supporting longitudinal beam on the airdrop cargo platform, making it impossible to carry out normal loading and unloading;

[0004] 2. The airdrop cargo platform lacks lateral limit and longitudinal guide devices during the towing process. Once the cargo platform has a large lateral displacement, serious consequences will occur. Summary of the invention
