Description
Technical field
The present invention relates to cable, and in particular to a kind of elevator is vertically accompanied cable for digital communication.
Background technology
Within elevator, due to the wireless access system of various interference sources, video monitoring or the network coverage be present, with elevator
Operation, signal can be extremely unstable.Therefore, most reliable access still must be by the way of wired.
However, common data cable can not meet.Because high-frequency digital signal transmits, consistent to the structure of medium
Property and stability are more sensitive, and the structure design and manufacturing process of this relation knife cable are in itself.
For the scene of fixed wiring, cable just no longer moves once installation.Therefore, construction of cable when dispatching from the factory is not
It can be changed because of moving for product.Multiple fixed safeguard measure during wiring, external force also can be effectively avoided to cable
Effect, and then ensure that cable will not the deformation on recurring structure because of effect at external force.
However, when cable application is when on the elevator of vertical lift, cable has to accompany with elevator lifting in itself.At this
In the individual motion process repeated for a long time, the flexural deformation repeatedly caused by cable follows elevator lifting, produced plus deadweight
Additional force effect, the structure of cable can not ensure stable homogeneous, and this transmission belt to high-frequency signal carrys out certain negative shadow
Ring, cause the hydraulic performance decline of product, it is unstable.Meanwhile the material of cable itself is also easily tired, is accelerated aging, influences the longevity
Life.In addition, the difference of cable length, will cause its deadweight different, corresponding required flexibility, toughness are also different, however, electricity at present
The apolegamy of cable this respect performance is highly difficult.
The content of the invention
For overcome the deficiencies in the prior art, vertically accompanied digital communication electricity it is an object of the invention to provide a kind of elevator
Cable, it can stablize and follow elevator lifting, flexibility, intensity are more suitable, ensure that signal is interference-free.
The purpose of the present invention is achieved through the following technical solutions：
A kind of elevator is vertically accompanied cable for digital communication, including nested elastic outer sheath, screen layer, elasticity successively from outside to inside
The wire of inner sheath and strands, covered with cellular insulating barrier, elastic outer sheath stretches out connection the appearance of wire
There is the elastic attached set of even number circular tube shaped, the attached set of elasticity is embedded with the first steel strand rope, and the attached set of elasticity is symmetrically set in elastic outer sheath
Appearance；Torus shaped cavity is provided with elastic outer sheath, flexible layer is removably filled with torus shaped cavity.
Further, screen layer includes plastic-aluminum layers of foil and wire braid, and wire braid is located on the outside of plastic-aluminum layers of foil.
Further, elastic outer sheath is convexly equipped with even number back-off head, is provided with one of back-off head and torus shaped cavity
The groove of connection, flexible layer are the flexible-belt being wound in torus shaped cavity, and the free end of flexible-belt is stretched out through groove, and elasticity is attached
Set side is provided with button hole, and button hole back-off is close to the free end of flexible-belt in back-off head and shroud；Cracking is provided with remaining back-off head
Groove.
Further, the attached set of elasticity is furnished with the connector being used for the attached set connection of another elasticity.
Further, connector includes main body and the hinge hole located at main body both sides, the attached set back-off of elasticity in hinge hole and with
Hinge hole is be hinged to be coordinated, and main body is embedded with the second steel strand rope.
Compared with prior art, the present invention has the advantages that：
Wire of the present invention is strands structure, improves the flexibility and bending property of cable, reduces cable and tow process
In bending stress；With reference to insulating barrier using cellular（Similar foaming）Structure, it on the one hand can save material 40%, dielectric loss
It is small, further lift flexibility, indefatigability, aging, meanwhile, elastic inner sheath, the elasticity of elastic outer sheath, also improve electricity
The flexibility and bending property of cable, reduce the bending stress during cable tows, wherein, stretched out on the outside of elastic outer sheath
The symmetrical attached set of elasticity, the booster action of structural strength is formd, 360 degree of second protection can be formed to cable, ensures cable
The work core of cable will not be conducted to pulling gravity and pulling force suffered by accompanying process, therefore recurring structure will not more be become
Shape, acted on reference to the signal shielding of screen layer, ensure that signal transmission of the cable during retinue is interference-free；More it is crucial that
Dismountable flexible layer that torus shaped cavity in elastic outer sheath is filled, also flexibility can be set according to flex capability demand
The amount of layer, to reach soft readjustment purpose, it is suitable for different length, weight cable and the flex capability needed for elevator trailing.
