Description
Technical field
The invention belongs to elevator product technical fields more particularly to a kind of steel wire rope for elevator core and preparation method thereof.
Background technique
Elevator is a kind of using motor as the vertical conveyor of power, be equipped with box-like gondola, for tier building multiply people or
Carrying cargo is widely used in each emporium, hotel, office building, high-rise residential building.Wirerope is that elevator is most important
One of component part, and Steel cord is that most heavy part is withstood forces in wirerope, and therefore, properties are to wirerope
Service life influences very big.
CN 103745779A discloses a kind of Multipurpose composite rope core, including fiber unit (optical cable), casing and fiber/
Resin compounded stick (cable core)；The fiber unit is located at the center of composite rope core, is made of several optical fibers and outer covering layer；
The casing is to cover with high temperature resistant high tenacity high molecular material in the outside of outer covering layer；Several fiber/resins are compound
Stick is assorted fibre enhancing high temperature resistant thermosetting resin composite materials, is centered around the periphery of casing, the fiber/resin compound bar
Internal layer is bearing bed, and outer layer is insulating layer；CN 102912663A discloses a kind of high-mechanic wirerope and preparation method thereof, should
Wirerope is to be twisted central strand twisting by outer layer strand, filling stock, internal layer stock packet and formed, in strand wire between steel wire and steel wire, stock with
It is in face contact shape between stock, outer layer strand, filling stock, internal layer stock orientation are left-hand lay, and central strand orientation is right-laid, outer layer strand, internal layer
Stock stock 7.5-7.8 times of diamond-mesh of the lay pitch, central strand, filling 6.4-6.6 times of diamond-mesh of the stock stock lay pitch, outer layer strand, filling stock, internal layer stock packet
Central strand is twisted, rope orientation is right-laid, and the ectonexine lay pitch is identical with orientation, and the lay pitch is 6.3-6.5 times of diameter of restricting.
Elevator higher for frequency of use, fast speed, the service life of wirerope and diameter uniformity are than common elevator
Will be high with wirerope, ride comfort can be influenced because wirerope diameter fluctuates using the elevator of common Sisal Hemp Rope Core wirerope
Degree can cause the service life shorter, while want to maintenance using the elevator of steel core class wirerope because wirerope oil storage performance is bad
Ask also higher.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of steel wire rope for elevator core and its production
Method, the Steel cord have the characteristics such as high intensity, high-modulus, high density and oil absorbency be good, at the same have it is good directly
