Layered cargo locking device for cargo aircraft

Abstract

The invention relates to the technical field of cargo racks, in particular to a layered cargo locking device for cargo aircraft, which includes a base plate, a support assembly is arranged on the bottom of the base plate, a column is provided on the top surface of the base plate, and the rod body of the column is The upper sleeve is provided with a sleeve, the sleeve runs through the layered plate, the lower part of the layered plate is provided with a load-bearing gear ring, the load-bearing gear ring is set on the rod body of the column, and the load-bearing gear ring is meshed with the drive component, and the drive component passes through the wire It is connected with the storage battery; the beneficial effect is: the bottom of the layered plate of the layered cargo locking device of the cargo plane proposed by the present invention is provided with four load-bearing gear rings to carry weight, and the load-bearing gear rings are driven by the drive assembly to rotate along the The column moves vertically, so as to adjust the distance between two adjacent layered plates.

Description

technical field [0001] The invention relates to the technical field of cargo plane racks, in particular to a layered cargo locking device for cargo planes. Background technique [0002] Cargo planes refer to planes that specialize in transporting cargo in the form of chartered flights or regular flights. Most civil cargo planes are converted from passenger planes; Reinforce the floor to improve the pressure bearing capacity, and set up a large cargo door at the front of the cargo cabin. The height of the door is more than 2 meters and the width is more than 3 meters. The cargo plane is also equipped with a floor roller (rod) system and a lifting crane to facilitate For loading and unloading of cargo, the cargo plane can be restored to a passenger plane or a passenger-cargo mixed plane (loading in the front cabin and people in the back cabin) when necessary. Such planes are usually called convertible planes; [0003] In the prior art, with the rapid development of the logist...

Problems solved by technology

[0003] In the prior art, with the rapid development of the logistics industry, in order to improve the timeliness of package delivery, logistics companies will choose an appropriate delivery method that eliminates the delivery time requirements of packages. Among them, freighter transportation is a transportation tool for fast and urgent packages. At present, , the freighter that specializes in transporting logistics packages will install racks inside to place logistics packages in layers to avoid the pressure loss caused by stacking too many packages; however, the shelf height is fixed, and the shelf cannot be adjusted according to the actual package size. The floor height, when the size of the logistics package is large, cannot be placed on the shelf; and the goods placed on the shelf are easy to cause the package to slip due to the turbulence of the airflow during the flight of the cargo plane. It is protected by covering the binding belt, and it is time-consuming to load and unload. It is laborious; and when you choose to unload the shelf and the goods from the cargo plane, you need to use a lifting crane to complete the work, and the crane is very easy to hit the cargo plane casing by mistake during the unloading process, resulting in damage to the cargo plane casing
