Three wrapping layers are sticked together with the first wrapping layer, will act at pulling force, pressure and Shear transfer on the rope strand of center to first
On wrapping layer, to reduce the tensile elongation of center rope strand.
Further, the present invention is by more carbon fibre tows at one, and without being bent and weaving, carbon fibre tow is in certainly
Right plumbness, external silicone materials carry out closely wrapping up in shield sizing, separation layer of the third wrapping layer as carbon fiber wire and steel wire,
Carbon fiber wire is vertically wrapped up in into shield wherein, to prevent generating carbonization effect after blocking fiber filament and steel wire contact.In addition, of the invention
Lubricating oil can reduce the friction in the second wire rope core main body between carbon fiber wire, and carbon fiber wire is made to keep plumbness.Further
Ground, since the present invention uses viscosity to make third wrapping layer for 1000~3000cst/25 DEG C of silicone materials, lubricating oil may be used also
To reduce the frictional force between the second wire rope core main body and third wrapping layer, extend the service life of traction rope.
Second wire rope core of the invention can bear sizable pulling force, the intensity that the carbon fibre tow of same cross-sectional area is carried
It is 7-9 times of common steel core.Since carbon fiber wire itself does not weave, distortion will not be generated, carbon fiber wire is damaged, gives full play to
The advantages of carbon fiber wire.In addition, carbon fibre tow weight only has a quarter of the steel wire of same cross-sectional area, it is possible to reduce 25%
Measured with rope.Further, in the case where same pulling force, the tensile elongation of the carbon fiber wire of same cross-sectional area is smaller than wirerope
70-90%.
The present invention can greatly increase the stretching resistance of traction rope using the second wire rope core, to reduce the whole outer of traction rope
Diameter, so that elevator traction size of wheel is substantially reduced and more energy saving, while it is a series of unfavorable also to reduce traction rope self weight bring
It influences, the tensile elongation of traction rope may further be reduced, prolong the service life length.
The material of first wrapping layer 10 of the invention is resin.Preferably, the material of first wrapping layer 10 is thermoplasticity
Polyurethane resin.Thermoplastic polyurethane resin has high-wearing feature and ductility, and has stronger natural aging and resist acidproof
Alkalinity further increases the wearability and high flexibility of traction rope, extends the service life of traction rope.
Compared with simple wirerope, traction rope tensile elongation of the invention is reduced significantly, although using carbon fiber wire come
Production traction rope can also reduce its tensile elongation, and still, the poor ductility of carbon fiber wire is easy to happen fracture, deposits in wirerope
In certain security risk.Traction rope of the invention passes through the mutual cooperation of center rope strand and peripheral rope strand, in toughness and extension
Property between obtain a good balance, extend its service life, meet the use of elevator.
