Abstract

The invention relates to a carbon fiber mixed and plastic coated steel rope, which comprises a rope core and steel wire bundles, wherein the rope core consists of a plurality of carbon fiber filaments and an anti-abrasion sheath wrapping the carbon fiber filaments; a plurality of strands of steel wire buckles are arranged outside the rope core; and synthesized plastic wraps the steel wire bundles and the rope core. According to the carbon fiber mixed plastic-coated steel rope, the rope core adopts carbon fiber filament bundles of which the tensile strength is more than 3,500 MPa and 7 to 9 times that of steel wires, and the weight of the carbon fiber filament bundles is only 1/4 of that of the similar steel wires; the carbon fiber mixed and plastic coated steel rope can bear the tension which is higher than that of the similar steel rope and has a wide application prospect in elevators.

Description

A kind of carbon fiber mixed with wrap up in plastic-steel rope

Technical field

A kind of elevator steel cable of the present invention relates in particular to a kind of carbon fiber mixing and wraps up in the plastic-steel rope.

Background technology

Now the traction driving wire rope of elevator all is to adopt braided steel wire to form, and different according to environment for use and function are adopted hemp core, employing steel core in the middle of the steel wire rope that has in the middle of the steel wire rope that has.These two kinds of patterns all play the effect of lubricated typing (hemp core) and gain in strength (steel core) respectively, though wherein steel core can be gained in strength, distinctive physical characteristic-rigidity is too strong, and are disconnected easily.

Summary of the invention

The present invention mixes and wraps up in the plastic-steel rope in order to overcome the above problems the carbon fiber that a kind of simple in structure, long service life, good mechanical property are provided.

Technical scheme of the present invention is: described steel cable comprises wire rope core, steel tendon; Described wire rope core is made up of the wear-resisting sheath of many carbon fiber wires and carbon fiber wire outerwrap; Described wire rope core is provided with the steel wire strand bundle outward, described steel tendon and wire rope core outerwrap synthetic plastic.

Described wire rope core is made up of the carbon fiber wire layer of the different numbers of multilayer, and the wire rope core center is the individual carbon fibers silk, and is the number that the center increases carbon fiber wire from the inside to the outside gradually with this individual carbon fibers silk.

Described wear-resisting sheath is the sheath that the aramid fiber braiding forms.

Described single steel wire bundle is knitted by the steel wire strand of many same diameter and is formed, and described steel wire strand bundle distributes along wire rope core circumference equal portions.

Wire rope core of the present invention adopts the carbon fibre tow of tensile strength more than 3500MPa, is 7-9 times of steel wire.And weight has only 1/4th of equal steel wire, this carbon fiber mixed with wrap up in plastic-steel rope and can bear the pulling force stronger than equal steel cable, the application on elevator has prospect very much.

The present invention's advantage compared with prior art is:

1), and thoroughly solved carbon fiber and metallic carbide, carburizing and electrochemical corrosion phenomenon can take place the steel wire compound tense because carbon fiber wire rope core surface adopts the braiding overcoat to wrap up in protects;

2) improve 3-5 service life doubly;

3) traction systems such as elevator traction wheel, directive wheel do not have wearing and tearing;

4) since the steel cable surface wrap up in and mould processing, so steel wire rope need not to refuel environmental protection;

5) reduce 25% use the rope amount, improve 40% anti-rupture pull force simultaneously;

6) diameter of rope reduces to bring diminishing of traction sheave diameter, and host driven power is reduced greatly, and energy-saving effect is remarkable;

7) the steel wire overall weight reduce make the elevator counterweight system balance diminish to bring and more comfortable take impression and reduce production costs.
