3 peripheral rope strands, 3 peripheral rope strands are centered around the periphery of 1 center rope strand, and 3 peripheral rope strands are the center of circle along circle using center rope strand
Circumferential direction is evenly arranged, and the central axis of 3 peripheral rope strands is arranged with the centerline axis parallel of center rope strand, and the first wrapping layer is filled out
Gap between the gap being charged between peripheral rope strand and peripheral rope strand and center rope strand；
The center rope strand includes the second wrapping layer and the first wire rope core main body, and the first wire rope core main body is by diameter
0.8mm, the steel wire twisting that intensity level is 2300MPa form, filled with profit between second wrapping layer and the first wire rope core main body
Lubricating oil；
The periphery rope strand includes third wrapping layer and the second wire rope core main body, and the second wire rope core main body is by diameter
0.5mm, the carbon fiber wire that intensity level is 3000MPa form, and the carbon fiber wire is in nature plumbness, the third wrapping layer
And second be filled with lubricating oil between wire rope core main body；
Wherein, second wrapping layer and third wrapping layer are made of silicone materials, and the viscosity of silicone materials is

Comparative example 1
A kind of elevator traction rope, including the first wrapping layer, the wire rope core main body being coated in first wrapping layer, wire rope core master
Body by diameter is 1.5mm, the steel wire twisting that intensity level is 2300MPa forms.
Comparative example 2
A kind of elevator traction rope, including the first wrapping layer, the wire rope core main body being coated in first wrapping layer, wire rope core master
The carbon fiber wire composition that body diameter is 1.5mm, intensity level is 3000MPa.
Embodiment 1-6 and the traction rope of comparative example 1 and 2 are carried out to the tension test of 5000 times and 10000 times, pulling force respectively
For the weight of normal elevator car, wherein embodiment 1-6 is identical with the length and diameter of the traction rope of comparative example 1 and 2, test
As a result as follows:
From the above it is found that compared with simple wirerope, the traction rope tensile elongation of the utility model is reduced significantly,
Although its tensile elongation can also be reduced by being made traction rope of carbon fiber wire, the poor ductility of carbon fiber wire is in steel wire
Rope, is easy to happen fracture, there is a certain security risk.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly cannot be practical to limit with this
Novel interest field, therefore equivalent variations made according to the claim of the utility model still belong to what the utility model was covered
Range.
