As shown in fig. 1, the utility model provides a double-layer bracket for improving the hanging efficiency of an airplane, which comprises an upright post 1, wherein the lower end of the upright post 1 is connected with one side of a lower-layer bracket 2, and the lower-layer bracket 2 is arranged on a walking lifting system 3; an upper layer bracket 4 is arranged above the lower layer bracket 2, and the upper layer bracket 4 is movably connected with the upright post 1, so that the upper layer bracket 4 can move to be separated from the space above the lower layer bracket 2.

The walking and lifting system 3 is a lifting platform device capable of moving on the ground, and has moving and lifting functions, and the double-layer bracket is fixed on a lifting platform of the walking and lifting system 3. During hanging operation, the bracket and the load 5 on the bracket are transported to a designated position of the belly of the airplane by the walking lifting system 3, the bracket is lifted to a certain height by the walking lifting system 3, and after the load 5 is fixed on the corresponding hanging point 6, the lifting platform is lowered, so that the load 5 is separated from the bracket. According to the utility model, the common bracket is designed into a double-layer bracket, the upper-layer bracket 4 can move to be separated from the upper space of the lower-layer bracket 1, and the problem that the lower-layer load 5 and the upper-layer bracket 4 cannot be hung due to collision caused by the lowering of the lifting platform by the walking lifting system 3 is avoided. The double-layer bracket can realize one-time lifting and simultaneously hang two loads 5, and the efficiency is obviously improved. Wherein, the upright post 1 is positioned at one side of the double-layer bracket, and one side of the double-layer bracket without the upright post 1 is close to the hanging point 6 during hanging.

As shown in fig. 2, in this embodiment, a connection assembly 7 capable of rotating is disposed on the upright post 1, and the connection assembly 7 is movably sleeved on the cross beam of the upper bracket 4, so that the upper bracket 4 can move axially along the connection assembly 7 and rotate up and down together with the connection assembly 7; the upright post 1 is also provided with a limiting device 8 which is used for limiting the rotation of the connecting component 7 and providing a supporting force for the upper bracket 4; the outer end of the cross beam is provided with a push handle 9.

Because the hanging points 6 of the loads 5 are fixed, the distance between the two loads 5 is also fixed, and the separation working space of the upper bracket 4 is limited, in the embodiment, the upper bracket 4 can be transversely pulled away through the connecting component 7 and can also rotate up and down along with the connecting component 7, and the arrangement of the connecting component 7 strengthens the mobility of the upper bracket 4, so that the separation operation of the upper bracket 4 during hanging is facilitated. In order to keep the upper tray 4 having sufficient supporting force for the load 5, a limiting device 8 is further provided in the present embodiment, and the limiting device 8 can limit the rotation of the connecting assembly 7, especially the horizontal direction, and can not rotate downwards, so as to avoid over-rotation of the connecting assembly 7, and also provide sufficient supporting force for the upper tray 4 by keeping the horizontal posture of the connecting assembly 7. Here, the limiting device 8 can also directly limit the cross beam of the upper bracket 4, and can also play a role in limiting the downward rotation of the connecting assembly 7 and the upper bracket 4. In order to enable the upper carriage 4 to be moved laterally, a push-pull hand 9 is also provided at the outer end of the upper carriage 4 remote from the load 5 in order to exert a force on the upper carriage 4. Here, the push-pull may be performed by a manual push-pull, or may be performed by an external booster, which is not limited herein.

In this embodiment, during the hanging, load 5 is placed to upper bracket 4 and lower floor's bracket 2, and walking lifting system 3 lifts double-deck bracket to appointed stores pylon side, and the one side of no stand 1 is towards the stores pylon, fixes the hanging point 6 of good load. Then the walking lifting system 3 lowers the lifting platform, the double-layer bracket descends a little distance along with the lifting platform, the load 5 on the upper-layer bracket 4 is separated, at the moment, the upper-layer bracket 4 is not influenced by the gravity of the load 5, and can move and be pulled out towards one side of the upright post under the action of the outer end tension force to be separated from the upper space of the lower-layer bracket 2. After the double-layer bracket continues to descend, the upper-layer bracket 4 is contacted with the lower-layer load 5, so that the upper-layer bracket 4 is forced to automatically rotate upwards. The upper tray 4 is rotated upward while being pulled out outward so as to be completely separated from the upper space of the lower tray 2, completing the separation of the double tray from the load 5.

It should be noted that the transverse pulling out of the upper bracket 4 can prevent the upper load 5 from limiting its upward rotation, and the inner end of the upper bracket 4 is usually provided with a detent to avoid completely disengaging from the upright; the bottom of the upper bracket 4 is usually provided with a flexible protection pad to avoid damage to the load.
