Description
Technical field
The present invention relates to traction elevator technical fields, more particularly to a kind of elevator traction rope.
Background technology
Current existing traction rope includes wire rope core and the outer rope strands of Duo Gen, and multiple outer rope strands are centered around the outer of wire rope core in the shape of a spiral
The periphery in week, traction rope is covered with inclusion enclave, in elevator operation, when traction rope acts on tensioned or bending force, and traction
Restrict integrally can be such that traction rope is generated on grooving around center axis rotation, rotation minutely slides, due to traction rope periphery
It is covered with resin layer, keeps the friction coefficient of traction rope and grooving high, grooving can limit the peripheral surface rotation of traction rope, therefore lead
The torque force generated inside messenger can play the inclusion enclave of peripheral surface shearing force, and long-time service can damage inclusion enclave,
So that inclusion enclave is cracked, and the steel wire inside traction rope is caused to expose and contacted with grooving, so that steel wire is rubbed, it is disconnected to generate cable wire
The service life of traction rope is shortened in the danger split, and there are security risks.

The integral diameter of traction rope, and then make to match the traction machine miniaturization used with traction rope, traction machine cost is reduced, elevator is saved
Hoistway space.
Further, the tensile strength of carbon fiber is greater than or equal to 3500MPa.
Further, the material of the first covering body is resin.First covering body is resin, and the first covering body is made to be easier
The gap between gap and peripheral rope strand and center rope strand between the peripheral rope strand of package, external rope stock and center rope strand rise
Effect is fixed and supported, while improving the wearability and high flexibility of leash, extends the service life of traction rope.
Further, resin is thermoplastic polyurethane resin.Thermoplastic polyurethane resin has high-wearing feature and extension
Property, and there is stronger natural aging and anti acid alkali performance, further increase the wearability and high flexibility of leash.
Further, peripheral rope strand has at least 6.
Further, the cross section of rope body is circle.Facilitate and realize Elevator weight sensor side and postposition, is conducive to elevator production
Product cope with various hoistway spaces, and the hoistway especially suitable for machine-roomless lift is arranged.
Further, the diameter of rope body is greater than or equal to 3mm.
Compared with prior art, the invention has the advantages that：
Periphery rope strand of the invention is arranged in parallel in the periphery of center rope strand, and axis is parallel with the axis of center rope strand, and
The axis of every peripheral rope strand is equal with the axial line distance of center rope strand, when traction rope can be made to pass through the grooving of traction rope sheave, leads
Rotation power is not generated inside messenger, avoids the effect due to rotation power that the first covering body of traction rope peripheral surface is made to cut
It cuts, and causes the too fast fracture by fatigue of the first covering body and destroy the performance of traction rope, extend the service life of traction rope, protect
Demonstrate,prove the operational safety of elevator.
