Description

Mechanical landing rope

Technical Field

The utility model relates to a cable field, concretely relates to machine falls rope.

Background

The machine falls the rope and is the main instrument that the helicopter throwed personnel, and at throwing personnel in-process, the one end that the machine falls the rope is connected on the export of helicopter, and the ground is thrown to the other end, and throwing personnel slide to ground along the rope.

However, most of the existing airborne ropes need to be manually tied to a helicopter when being used, so that the existing airborne ropes are extremely inconvenient to use and are easy to cause safety accidents. Therefore, a machine descending rope which is convenient and safe to use is needed in the market.

For solving the deficiencies existing in the prior art, the utility model provides a machine falls rope.

The technical scheme of the utility model is that:

the utility model provides a machine rope that falls, its characterized in that: the rope comprises a rope ring, a main rope body and a heat-shrinkable tube, wherein a plurality of connecting ropes are arranged on the rope ring; the main rope body is a multi-strand cable, the connecting rope is intertwined with the single-strand rope of the main rope body respectively to be woven together to form a connecting area, the length of the connecting area is 25-35 cm, the heat-shrinkable tube is arranged on the connecting area, and the length of the heat-shrinkable tube is 25-35 cm.

Further, the rope ring is formed by weaving one or more of an ultrahigh molecular weight polyethylene rope, an aramid rope, a polyarylate fiber rope, a polyimide fiber rope and a PBO fiber rope.

Further, the main rope body is formed by weaving one or more of nylon filament or staple fiber, polyester filament or staple fiber, and acrylic filament or staple fiber.

Further, the rope ring is a 12-strand cable.

Furthermore, the connecting rope is formed by extending and weaving single-strand ropes forming a rope ring.

Further, the main rope body is an 8-strand cable.

Further, a sheath is arranged on the rope ring.

Further, the sheath is made of nylon.

Further, the heat shrink tube comprises an outer layer and an inner layer, wherein the outer layer is made of cross-linked polyolefin, and the inner layer is made of hot melt adhesive.

The utility model discloses the beneficial effect who reaches does:

the utility model discloses set up the becket at the one end of rope falls at the machine, make it directly can hang at the corresponding fixed part of helicopter when using, convenient to use saves time, has improved efficiency.

Meanwhile, the rope ring is additionally provided with the protective sleeve, so that the abrasion resistance of the rope ring can be effectively increased, and safety accidents caused by the fact that the rope ring is broken when the rope ring is used are prevented.

In addition, the connection rope of the rope ring is woven and wound with the single-strand rope of the main rope body, and the rope is firmer. Moreover, the utility model discloses set up the pyrocondensation pipe again in the joining region, further strengthened the combination of becket bridle and the main rope body.

Detailed Description

To facilitate understanding of the present invention for those skilled in the art, embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides a mechanical landing rope, which comprises a rope ring, a main rope body 4 and a heat-shrinkable tube 3. The rope ring 1 is a 12-strand cable, and the rope ring 1 is formed by weaving one or more of an ultrahigh molecular weight polyethylene rope, an aramid rope, a polyarylate fiber rope, a polyimide fiber rope and a PBO fiber rope. The rope ring 1 is provided with a sheath 2, and the sheath 2 is made of nylon. The sheath 2 can play the effect of protection, wear-resisting to the becket bridle 1, prevents that the becket bridle 1 from being worn out in the use, and then arouses the incident. The rope ring 1 is provided with a plurality of connecting ropes.

The main rope body 4 is an 8-strand cable, and the main rope body 4 is formed by weaving one or more of nylon filament or staple fiber, polyester filament or staple fiber, and acrylic filament or staple fiber. The connecting rope is intertwined respectively with the single strand rope of main rope body 4 and is woven together and form the joining region, the length of joining region is 25 ~ 35cm, pyrocondensation pipe 3 sets up on the joining region, the length of pyrocondensation pipe 3 is 25 ~ 35 cm. The heat-shrinkable tube 3 is used for preventing the connection rope of the rope ring 1 from being separated from the weaving structure of the main rope body 4 when the rope is stressed, so that safety accidents are caused.

The heat shrinkable tube 3 comprises an outer layer and an inner layer, wherein the outer layer is made of cross-linked polyolefin, and the inner layer is made of hot melt adhesive.

Specifically, the weaving method of the rope ring 1 and the connecting method of the rope ring 1 and the main rope body 4 are as follows: firstly, rope loop ropes forming the rope loop 1 are inserted into the bottom end of a connecting area of a main rope body 4 to enable the rope loop ropes to be divided into two parts with the same left and right length, then the left and right parts are crosswise woven into the main rope body 4 along grains of the main rope body 4, and the part woven into the main rope body 4 is the connecting rope. Finally, the left and right remaining portions of the looped rope are unraveled, and then the unraveled strands are cross-woven together to form the loop 1 and fixed at the crossing area.

The above-mentioned embodiments of the present invention do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
