Description

A kind of express elevator optoelectronic composite cable

Technical field

The utility model relates to optical fiber cable technical field, specifically a kind of express elevator optoelectronic composite cable.

Background technique

With the continuous development of optical communication technique, optical fiber cable will be used wider and wider it is general, optical cable have light weight, body The excellent characteristics such as the small, electromagnetism interference of product.More and more high rise elevators are using optical cable as communication or the transmission of video at present Medium replaces traditional communication cable, because elevator optical cable uses freely-suspended wire laying mode, it is necessary to elevator box one Lifting, so elevator optical cable is required to bear larger pulling force and buckle resistance energy for a long time.Mostly elevator cable is all Using steel strand wires as tensile elements, cause whole elevator cable more stiff, volume is big, quality is big, while elevator optical cable is also Should have compared with high-flexibility and meet up to a million round-trip movements of elevator.

Currently, most of elevator optical cable is only used as the medium of communication or video monitoring, elevator box power supply also needs Individual elevator cable, such wire laying mode maintenance and installation difficulty are big, occupy hoistway space, higher cost, there is only a few Using traditional optoelectronic composite cable, because of its unreasonable structural design, the disadvantages of own vol is big, quality weight, be only applicable in speed it is low, It freely dangles apart from the scenes such as short, can no longer meet now at high speed, the long elevator applications demand freely dangled, both the above It is all the long-life that elevator cable market is unable to satisfy using traditional material, high speed, bend resistance, easily in lift type optical cable Construction maintenance can require.In addition, elevator cable is chronically in the environment of moist darkness, rare a elevator cable can be same in the market When meet anti-mildew, protection against rodents and the demand.

Summary of the invention

The utility model provides a kind of express elevator optoelectronic composite cable, it is intended to solve the above-mentioned disadvantage of existing elevator cable And design, there is high speed, bend resistance, long-life, easily construction all advantages, be highly suitable to be applied for high-rise or super high rise building Elevator.

In order to achieve the above-mentioned object of the invention, the utility model adopts the following technical solution:

A kind of express elevator optoelectronic composite cable, section is at flat, and center is fiber unit, and the fiber unit includes Two tight tube fibers and two aramid fiber beams, tight tube fiber are followed successively by optical fiber, buffer layer and tight sleeve layer from the inside to the outside, tight tube fiber and Aramid fiber beam has been orderly arranged outside each inner sheath, spiral armor and aramid fiber braiding layer；The two sides of fiber unit are respectively arranged with Conductor element, the conductor element are followed successively by conductor, insulating layer and aramid fiber braiding layer from the inside to the outside；Oversheath clad optical fiber unit And conductor element.

Preferably, the outer lateral edge cable length direction of the oversheath is symmetrical arranged there are four groove.

Preferably, the elliptical length that the oversheath section is formed is 25mm, width 6.2mm, oversheath The distance of outer edge and aramid fiber braiding layer is at least 1.0mm, and distance is at least between oversheath outer edge and spiral armor edge For 1.0mm.

Preferably, the inner sheath and jacket material are thermoplastic polyurethane.

Preferably, the inner sheath surface is handled using frosting technology, and smooth surface is processed into frosting, spiral shell Revolving armor, closely spiral is peripheral in inner sheath.

Preferably, the tight sleeve layer uses thermoplastic polyester elastomers material.

Preferably, the buffer layer uses transparent resin or silica gel material.

The utility model has the beneficial effects that:

(1) tight tube fiber is provided with buffer layer, greatlys improve charge stripping efficiency, reduces the construction time.

(2) since the tight sleeve layer of tight tube fiber uses Hytrel(thermoplastic polyester elastomers) material, so that fixed light Fibre has the performances such as obdurability and elasticity, anti-deformation, protecting against shock, flex stiffiness, low temperature elasticity, avoids under elevator cable low-temperature bending Tight tube fiber restrictive coating cracking.

(3) inner sheath is had many advantages, such as mould proof, fire-retardant using special thermoplastic polyurethane material, avoids elevator cable long-term It goes mouldy in moist dark environment, and then influences entire elevator cable performance.Multiply aramid fiber is provided with mosaic mode in inner sheath Beam avoids aramid yarn loose, improves interior shield tensile strength.In addition, interior shield is increased using surface using frosting technology processing Interior shield and spiral armor contact force avoid elevator cable interior shield are opposite with armor when moving to slide, cause in interior shield optical fiber by Being self-possessed to interior shield and moving brief acceleration influences.

(4) make elevator cable that there is protection against rodents at interior shield protective layer using helical steel band armouring, anti-collapse advantage improves simultaneously Elevator cable bending property, avoids overbending from leading to fibercuts.

(5) it uses aramid fiber mesh grid to replace traditional braided wires as tension member, existing elevator cable weight is reduced Nearly one third, allows tensile strength to be increased to 3000N by 2000N, and free suspension distance at least improves half.

(6) the electric insulation layer surface of power conductor periphery increases electric insulation layer and aramid fiber using frosting technology processing The contact force of braiding layer causes gap between electric insulation layer and oversheath after avoiding elevator optoelectronic composite cable long-time use Increase, when power supply line free suspension bears the weight of itself, shortens its service life.

(7) jacket material uses anti-mildew, anti-ultraviolet thermoplastic polyurethane material, so that elevator cable is with wear-resisting The features such as performance is splendid, anti-impact pressure, corrosion-resistant, water-fast, oil resistant, long service life, while avoiding the causing property of mildew of oversheath It can be deteriorated.

(8) sheath external periphery outline is using symmetrical " groove " design, when elevator cable being avoided to repeat to bend in jacket material Portion's stress concentrations cause sheath to crack.In addition, elevator cable stripping and power supply line is facilitated to separate with photoelectric source.

(9) using the above structure design and material, so that elevator cable operating ambient temperature is expanded to -40 ~ 85 DEG C, conventional photo Composite rope temperature application range is only -20 ~ 70 DEG C, meets exceedingly odious temperature environment requirement.
