Abstract

The invention relates to a carbon fiber bilayer plastic wrapped steel rope specially used for an elevator and belongs to the technical field of elevators. The carbon fiber bilayer plastic wrapped steel rope specially used for the elevator is provided with a carbon fiber rope core, wherein a synthetic plastic inner protective layer is wrapped outside the carbon fiber rope core; a suction disc which is densely covered by ranks of micro ridges and slots is wrapped outside the inner protective layer; a braided steel wire rope is arranged outside the suction disc, and a synthetic plastic shell is extruded and wrapped outside the steel wire rope. The carbon fiber bilayer plastic wrapped steel rope disclosed by the invention has a scientific and reasonable structure; an intermediate sizing rope core adopts a carbon fiber plastic wrapped rope; a plastic wrapped surface imitates the mode of the suction disc of a wall gecko, and the suction disc which is densely covered by ranks of micro ridges and slots is arranged, so as to enhance the binding ability of the carbon fiber bilayer plastic wrapped steel rope with other materials; the shell is wrapped by the synthetic plastic; and the tensile strength of the carbon fiber resin composite material is 3500MPa or above and is 7-9 times that of a steel wire while the weight of the carbon fiber resin composite material is one fourth of the weight of the steel wire of the same class, thus the carbon fiber bilayer plastic wrapped steel rope disclosed by the invention has a prospect in application of the elevator and is a replacement product of an elevator hoisting rope.

Description

The special carbon fiber bilayer of a kind of elevator wraps up in plastic-steel rope

Technical field

Patent of the present invention relates to the special carbon fiber bilayer of a kind of elevator and wraps up in plastic-steel rope, belongs to elevator technology field.

Background technology

The traction-driven steel cable of present elevator is all adopt braided steel wire to form, and according to the difference of environment for use and function, adopts hemp core, adopt steel core in the middle of some steel wire ropes in the middle of some steel wire ropes.This two profiles formula plays the effect of lubrication sizing (hemp core) and gain in strength (steel core) all respectively, although wherein steel core can be gained in strength, distinctive physical characteristic-rigidity is too strong, easily breaks.And although hemp core lubricates stereotyped, tensile strength is poor.So the production of elevator, installation and user wish that a kind of intensity is high, lubricate stereotyped, the steel wire rope for elevator of long service life.

Summary of the invention

The object of the invention is exactly the needs meeting market, provides a kind of intensity high, lubricates stereotyped, and the special carbon fiber bilayer of elevator of long service life wraps up in plastic-steel rope.All adopt carbon fiber to wrap up in plastic-steel rope the wire rope core in the middle of steel cable or steel core, then outside after braided steel wire again at the outer wrap synthetic plastic of rope, form a kind of carbon fiber bilayer and wrap up in plastic-steel rope.

The object of the present invention is achieved like this, the special carbon fiber bilayer of a kind of elevator wraps up in plastic-steel rope, be provided with carbon fiber wire rope core, carbon fiber wire rope core outer wrapping synthetic plastic sheath, the sucker of the several rows of fine ridge, groove is thick with at synthetic plastic sheath outer wrapping one deck, at the outer braided wire rope of sucker, outside steel wire rope, extrude synthetic plastic shell.

The material of sucker can be metal or plastics.

The present invention is scientific and reasonable for structure, and middle sizing wire rope core adopts carbon fiber to wrap up in and moulds rope, wrap up in and mould the sucker pattern that gecko is imitated on surface, arrange the sucker that one deck is thick with several rows of fine ridge groove, to increase the associativity with other material.Shell adopts the advantage of synthetic plastic parcel to have: (1) can be avoided carbon fiber to hold flying away, the defect (preventing from causing short circuit to electric wiring) of easy conductive this respect; (2) can solve carbon fiber should not with the defect of metal composite.Wire rope core adopts to wrap up in moulds carbon fiber, and outside is made into steel wire rope by steel wire strand again, then again wraps up synthetic plastic formation compound in the outside of rope and wraps up in plastic-steel rope.Because the tensile strength of carbon fiber resin composite material is at more than 3500MPa, be 7-9 times of steel wire, and weight only has 1/4th of equal steel wire, the application on elevator very has prospect, is the renewal product of elevator rope.

the concrete advantage of the present invention also has:

1.wrap up in mould process because carbon fiber rope wicking surface adopts, and thoroughly solve carbon fiber and metallic carbide, carburizing and electrochemical corrosion phenomenon can occur steel wire compound tense;

2. compare the life-span with conventional lift steel cable and improve 3-5 doubly;

3. the traction system such as elevator traction sheave, directive wheel is without wearing and tearing;

4. wrap up in due to steel wire rope surface and mould process, so steel wire rope is without the need to refueling, environmental protection;

5. reduce 25% use rope amount, simultaneously raising 40% anti-rupture pull force;

6. the 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 reduction of steel wire overall weight makes elevator counterweight system balance diminish and brings more comfortable feeling for taking and reduction production cost.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

In figure: 1 carbon fiber wire rope core, 2-in-1 one-tenth plastics sheath, 3 suckers, 4 steel wire ropes, 5 synthetic plastic shells.

Detailed description of the invention

Wrap up in synthetic plastic sheath 2 outer the squeezing of carbon fiber wire rope core 1, be thick with the sucker 3 of several rows of fine ridge groove at synthetic plastic sheath outer wrapping one deck, the material of sucker is metal or plastics.At the outer braided wire rope 4 of sucker, outside steel wire rope, extrude synthetic plastic shell, form the special carbon fiber bilayer of elevator and wrap up in plastic-steel rope.

Claims

1. the special carbon fiber bilayer of elevator wraps up in plastic-steel rope, comprise carbon fiber wire rope core and shell, carbon fiber wire rope core outer wrapping synthetic plastic sheath, it is characterized in that, the sucker of the several rows of fine ridge, groove is thick with at synthetic plastic sheath outer wrapping one deck, at the outer braided wire rope of sucker, outside steel wire rope, extrude synthetic plastic shell.
