The hanging frame 3 is a square frame, the hanging frame 3 comprises two clamping plates, the lower ends of the two clamping plates are connected through a round bar, and the upper ends of the two clamping plates are connected through a connecting rod.

The reinforcing rod 31 is arranged between the round rod and the connecting rod on the hanging frame 3, the reinforcing rod 31 is parallel to the round rod and the connecting rod, and the reinforcing rod 31 is positioned on the upper side of the cross beam 4. The stability of the hanger frame 3 is improved by the reinforcing rods 31. In use, the reinforcing bar 31 is close to the cross beam 4, and after the front end or the rear end of the cross beam 4 is inclined by a certain angle, the reinforcing bar 31 can abut against the cross beam 4, so that the cross beam 4 is prevented from being excessively inclined.

The middle part of the connecting rod is fixedly provided with a hanging wheel 30, and an arc-shaped groove is processed on the outer circular surface of the hanging wheel 30 along the circumferential direction. When using, the arc recess is the half slot, and the diameter of half slot is unanimous with rope A2's diameter, and the pot head of keeping away from rings 1 on rope A2 is at the half slot of hanging wheel 30, and the half slot has limiting displacement to rope A2, can avoid keeping away from rings 1's one end on rope A2 and shift along the length direction of connecting rod in hoist and mount process. In addition, compared with the case where the rope a2 is directly tied to the connecting stick, the rope a2 is tied to the sheave 30, so that the force-receiving area of the rope a2 can be increased, which contributes to the extension of the service life of the rope a 2.

The bottom of the cross beam 4 is provided with a plurality of limiting notches 40 in parallel, and the limiting notches 40 are arranged along the width direction of the cross beam 4. When in use, the limiting notch 40 is in an inverted U shape, and the size of the limiting notch 40 is matched with the diameter of the round rod.

The bearing assembly 5 comprises a bearing pipe 50 and two lifting hooks A51, the top of the bearing pipe 50 is detachably connected with the cross beam 4 through two vertical plates, a protection pad A52 is bonded at the bottom of the bearing pipe 50, and the two lifting hooks A51 are symmetrically arranged on the bearing pipe 50 and are respectively positioned on the front side and the rear side of the bearing pipe 50. In use, the hooks a51 are used to connect to the ends of the line B60 and the pad a52 is a foam pad to prevent the bottom of the bearing tube 50 from damaging the surface of the aircraft 8.

Two contained angle between lifting hook A51 is 45 ~ 90 degrees, and all installs on two lifting hooks A51 and prevents the dropout. Compare the condition that two lifting hooks A51 all vertically arranged, the contained angle between two lifting hooks A51 is 45 ~ 90 degrees, helps avoiding the tip of rope B60 to deviate from on lifting hook A51. The hook a51 is provided with a trip prevention feature that prevents the end of the rope B60 from falling out of the hook a 51.

The supporting plate assembly 6 comprises a rope B60 and a supporting plate 61, the supporting plate 61 is sleeved on the rope B60, and a protection pad B62 is adhered on the supporting plate 61. In use, the position of the support plate 61 in the longitudinal direction of the rope B60 can be adjusted as necessary. Pad B62 is a foam pad to prevent blade 61 from scratching the surface of aircraft 8.

Product connecting part B7 includes bearing block 70, and bearing block 70's one end is articulated with crossbeam 4, and the other end articulates there is connecting block 71, and the bottom processing of connecting block 71 has rings holding tank, and has the pinhole at the position processing corresponding with rings holding tank on the connecting block 71. When using, install rings B on aircraft 8's the shell, rings holding tank's shape and size and rings B phase-match use the round pin axle can link together connecting block 71 and rings B, and rings holding tank can avoid rings B to rotate at the in-process of hoist and mount aircraft 8. One end of the bearing block 70 is hinged with the cross beam 4, and the other end is hinged with the connecting block 71, so that the position of the connecting block 71 can be quickly adjusted, and the hanging ring accommodating groove is aligned with the hanging ring B.

Aircraft hoist, its theory of operation or use as follows:

when the aircraft 8 needs to be lifted, the operator controls the travelling crane to move above the aircraft lifting appliance, and hooks the lifting appliance on the travelling crane to the lifting ring A1. And controlling the travelling crane to slowly move the aircraft lifting appliance to the position above the aircraft 8, loading the lifting ring B on the aircraft 8 into the lifting ring accommodating groove on the connecting block 71, and inserting the pin shaft to complete the connection work of the lifting ring B and the product connecting part B7. One end of the rope B60 is looped into the hook a51 and then the other end of the rope B60 is passed under the aircraft 8 and looped into the other hook a51, adjusting the position of the pallet 61. The crane is controlled to lift the aircraft 8, and in order to prevent the supporting plate assembly 6 from crushing the shell of the aircraft 8, the rope B60 or the supporting plate 61 is held by hands until the rope B60 is tensioned during lifting.

In addition, if the mass center of the aircraft 8 has deviation during hoisting, one of the hoisting frames 3 can be moved forward or backward for a certain distance, and the round bar is clamped into the corresponding limiting notch 40 until the hoisting requirement is met. During the hoisting process, the aircraft 8 is required to be in a horizontal position, and the front and the back of the aircraft 8 are required to be held by hands to prevent the aircraft 8 from swinging. And after the aircraft 8 is lifted to a required position and is placed stably, the pin shaft is removed to separate the connecting block 71 from the lifting ring B, and then the end part of the rope B60 is taken out of the lifting hook A51, so that the aircraft sling can be separated from the aircraft 8.

In conclusion, the aircraft lifting appliance can be used for lifting the aircraft 8 within a certain length range, and after the supporting plate assemblies 6 with different lengths are replaced, the aircraft lifting appliance can also be used for lifting the aircraft 8 with different diameters, so that the application range is wide.
