Rope for multi-person suspension transfer of helicopter

Abstract

The rope is used for transferring personnel on the rope in a pairwise side-by-side multi-layer suspension mode and comprises a main body woven rope, the head end of the main body woven rope is a connector used for being connected to the helicopter, and a plurality of suspension units are distributed along the area, close to the tail end, of the main body woven rope. The suspension unit comprises a transfer rope and a protection rope which are woven on the main body weaving and winding rope in a penetrating and winding manner; for each suspension unit, the same transfer rope forms two rope rings which are separated up and down and staggered left and right on the main body weaving and winding rope, and the same protection rope penetrates through the two sides of the transfer rope to form two rope rings which are arranged side by side left and right. During use, two persons are located on the two sides of the hanging unit and are hung on the transfer rope ring and the protection rope ring on the side through the safety buckles at the same time. The distance between the adjacent layers of hanging units can ensure that people on the adjacent layers do not interfere with each other during use. The rope can transfer personnel in a pairwise side-by-side multi-layer hanging mode, and transfer is safe and reliable.

[0018] The present application is further described below in conjunction with the accompanying drawings and embodiments.

[0019] The present application discloses a rope for helicopter multi-person suspension transportation, which is used to transport personnel in a multi-layer suspension mode of two-by-two side-by-side on the rope, including a main braided rope 3, the head end of the main braided rope 3 is a connector 2 for connecting to the helicopter, and a plurality of suspension units are distributed along the area near the tail end of the main braided rope 3, and the suspension unit includes a transfer rope 4 and a protection rope 5 woven on the main braided rope 3 in an interlaced braided manner; for each suspension unit, the same transfer rope 4 forms two rope rings separated up and down and staggered left and right on the main braided rope 3, and the same protection rope 5 is inserted on both sides of the transfer rope 4 and forms two rope rings side by side left and right. When in use, two people are located on both sides of the suspension unit and are suspended on the rope rings of the transfer rope 4 and the rope rings of the protection rope 5 on the side at the same time through the safety buckle 8; the distance between the adjacent layers of suspension units can ensure that the personnel of the adjacent layers do not interfere with each other when in use. Among them, the safety buckle 8 is a matching connector on the safety belt of the person to be transported, which is not a part included in this application and belongs to a conventional part.

[0020] When it is necessary to complete the task of rapid transfer of multiple people, the helicopter carries the rope to the mission site and hovers above the people to be transferred. The on-board operator connects the head end of the rope to the helicopter rescue winch or the helicopter's special suspension point and then drops the rope. When all the suspension units on the main braided rope 3 are in contact with the ground, the people to be transferred are arranged in pairs on both sides of the suspension units along the line in order from the upstream suspension unit to the downstream suspension unit. The people to be transferred are evenly distributed on the left and right to ensure the balance of the center of gravity. If the number of people is odd, the last layer is a single person. The people to be transferred are simultaneously suspended on the rope rings of the transfer rope 4 and the protection rope 5 on their side through the safety buckle 8. After all the suspended people are suspended and confirmed to be safe, the helicopter slowly rises to lift the suspended people and transfer them to the target position.

[0021] According to the above scheme: each suspension unit can hang two people side by side on both sides of the main braided rope 3, and the suspension units along the main braided rope 3 can also realize multi-layer suspension, and the rope can transport personnel in a way of two-by-two multi-layer suspension; the transfer rope 4 and the protection rope 5 are woven on the main braided rope 3, with great bearing capacity, and the safety buckle 8 is simultaneously hung on the rope rings of the transfer rope 4 and the protection rope 5 on the side, so the transportation is safe and reliable. The rope can be used with medium or heavy transport helicopters or rescue helicopters, and is suitable for completing tasks such as soldier combat transportation and rapid evacuation of personnel.

[0022] like Figure 1 As shown, in this embodiment, preferably, the tail end of the main braided rope 3 is tied with cotton and linen rope and coated with glue to solidify, which can prevent the tail of the main braided rope 3 from loosening.

[0023] like Figure 2As shown, in the present embodiment, preferably, after the transfer rope 4 passes through the main braided rope 3 to form two rope rings, its two ends are braided together by spiral interlacing and braiding. After the two ends of the transfer rope 4 are braided together, the leaked rope end 6 is tied with tape and then coated with glue for protection, thereby improving the connection reliability and preventing the transfer rope 4 from unraveling.

[0024] like Figure 2 As shown, in the present embodiment, preferably, after the protective rope 5 passes through the main braided rope 3 to form two rope rings, its two ends are braided together by spiral interlacing and braiding. After the two ends of the protective rope 5 are braided together, the leaked rope ends 6 are tied with adhesive tape and then coated with adhesive for protection, thereby improving the connection reliability and preventing the protective rope 5 from unraveling.

[0025] like Figure 2 As shown, in this embodiment, preferably, a knot 7 is tied between two formed rope loops of the protection rope 5 to fix one side of the protection rope 5, which can effectively separate the two rope loops of the protection rope 5 and avoid the protection rope 5 from being cluttered.

[0026] The connector 2 of the main braided rope 3 can be directly hung on a helicopter rescue winch or a special hanging point. When using it, it is necessary to pay attention to whether the opening size of the special hanging point can normally hang the connector 2, and pay attention to the wear of the main braided rope 3. It is best to perform anti-wear protection; the connector 2 of the main braided rope 3 can also be hung on a helicopter rescue winch or a special hanging point through a hanging ring 1. The hanging ring 1 is made of high-strength metal ring, a single one can bear more than 8 tons, and two hanging rings 1 are used for simultaneous suspension to improve reliability.

[0027] In this embodiment, the length of the main braided rope 3 is at least 20 meters, and four groups of suspension units are distributed on the main braided rope 3, and the spacing between the suspension units is 2 meters, so that 8 people can be transported at the same time. The length of the main braided rope 3 and the number and spacing of the suspension units are not limited to this and can be set according to actual needs.

[0028] In this embodiment, the main braided rope 3 is made of gray-green meta-aramid polyester, and the main body can withstand a static tensile force of more than 16 tons. The transfer rope 4 and the protective rope 5 are both braided with polyester ropes, and a single rope can withstand a static tensile force of 4 tons. The use of flame-retardant materials can prevent the rope from threatening the safety of personnel and helicopters after an accidental fire.

[0029] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
