[0010] Preferably, there are two rope ring hanging points between the safety rope ring and the lifting rope, there is a rope ring hanging point between each hanging rope ring and the lifting rope, and the two rope ring hanging points of the hanging rope ring pair are located between the two rope ring hanging points of the corresponding safety rope ring.

[0011] Preferably, the upper part of the lifting rope is the rope throwing area, and the lower part of the lifting rope is the hanging area. The length of the rope throwing area is 10m-20m. The safety hanging structures in the hanging area are evenly arranged, and the spacing between adjacent safety hanging structures is 2m-2.5m. The total length of the lifting rope is 30-38 meters.

[0012] Preferably, 8-12 safety suspension structures are provided in the suspension area.

[0013] A hanging evacuation structure for a helicopter comprises a safety structure for a hanging evacuation rope, wherein the upper end of the hanging rope is fixed to the cabin of the helicopter, and further comprises a main hanging rope and a backup safety rope, wherein the upper ends of the main hanging rope and the backup safety rope are respectively hung on a safety rope ring and a hanging rope ring, and the other ends of the main hanging rope and the backup safety rope are hung on the safety belts of the evacuees.

[0014] Preferably, the upper end of the hoisting rope is hung on four hoisting points on the cabin ceiling of the helicopter through four evenly arranged connecting ropes, and the four connecting ropes are arranged in an inverted quadrangular pyramid shape.

[0026] See also Figure 1 , Figure 2 , Figure 4 A hanging evacuation rope for a helicopter comprises a hoisting rope 1, on which a pair of hanging rope rings (two hanging rope rings 2) are arranged, and a safety rope ring 3 is also arranged on the hoisting rope 1. The number of the safety rope rings 3 is the same as the number of the hanging rope ring pairs, and the safety rope ring 3 passes through the corresponding hanging rope ring pairs to form a safety suspension structure. The hoisting rope 1, the hanging rope ring pairs, and the safety rope ring 3 are made of ropes of different colors, and are all ultra-high molecular materials. They are woven into 12 strands. The hoisting rope 1 is a flat rope, and the rope ring hanging points on the hoisting rope are woven with rope loops, and the rope loops are coated with polyester material for connecting with the hanging rope ring pairs and the safety rope ring 3. There are two rope ring hanging points between the safety rope ring and the hoisting rope, and there is one rope ring hanging point between each hanging rope ring and the hoisting rope. The two rope ring hanging points of the hanging rope ring pair are located between the two rope ring hanging points of the corresponding safety rope ring and are evenly distributed.

[0027] See the table below:

[0028]

[0029]

[0030] The upper part of the hoisting rope 1 is the rope throwing area 4, and the lower part of the hoisting rope 1 is the hanging area 5. The length of the rope throwing area 4 is 10m-20m. The safety hanging structures in the hanging area 5 are evenly arranged, and the spacing between adjacent safety hanging structures is 2m-2.5m. In this embodiment, 8-12 safety hanging structures are arranged in the hanging area 5.

[0031] See also Figure 1-Figure 3 A hanging evacuation structure for a helicopter includes a safety structure for a hanging evacuation rope. The upper end of the lifting rope 1 is fixed to the helicopter cabin. It also includes a main hanging rope 9 and a backup safety rope 10. The upper ends of the main hanging rope 9 and the backup safety rope 10 are respectively hung on a safety rope ring 3 and a hanging rope ring 2. The other ends of the main hanging rope 9 and the backup safety rope 10 are hung on the safety belt 7 of the evacuee. The upper end of the lifting rope 1 is hung on four lifting points on the ceiling of the helicopter cabin through four evenly arranged connecting ropes 6. The four connecting ropes 6 are arranged in an inverted quadrangular pyramid shape. In this embodiment, the connecting rope is connected to the hanging holes on both sides of the ceiling in the cabin with SR steel locks. See Figure 3The back of the safety belt 7 of the evacuee is provided with a main connection part and a backup connection part. The main connection part is arranged at the center of the back of the safety belt 7, and the backup connection part is located at the back of the shoulder strap 8 of the safety belt 7.

[0032] In this embodiment, the main suspension rope 9 includes two SR steel locks and one SR connecting rope. The main connecting part is a steel ring. The SR steel lock is connected to the steel ring without locking the lock nut. The backup safety rope 10 includes a CAMP steel lock and a CAMP flat belt. The backup connecting part is a braided sleeve. The CAMP flat belt is connected to the braided sleeve in a threaded manner. The main suspension rope 9 and the backup safety rope 10 must be hung in two colors of rope rings (hanging rope ring and safety rope ring) at the same time. Under normal circumstances, only the hanging rope ring bears the weight. When the hanging rope ring breaks, the safety rope ring is temporarily hung with the main suspension rope 9 and the backup safety rope 10 to bear the weight.

[0033] Directions:

[0034] 1. The helicopter takes off and hovers at a height of 10-18 meters;

[0035] 2. A dedicated person shall drop the lifting rope from the bottom hatch and observe;
