Abstract
The invention relates to a traveling elevator cable. The traveling elevator cable comprises a flat cable sheath, wherein cable cores are respectively arranged at two ends in the cable sheath; a butterfly cable is arranged in the middle in the cable sheath. The traveling elevator cable is long in service life, and is unlikely to break after being used for a long time, thereby guaranteeing the transmission stability of network signals.
Description
Technical field
The present invention relates to a kind of trailing elevator cable, belong to construction of cable technical field.
Background technology
In recent years, along with continuing to increase of China's capital construction dynamics, there are unprecedented blowout market in real estate, skyscraper continues to bring out, the demand of elevator increases sharply, along with the increase of elevator functions demand, in elevator trailing cable, holding wire, screen line, grid line are obtained for extensive use, and the grid line in current trailing elevator cable mostly adopts 5 class grid lines, and what this cable adopted is sub-thread soft copper silk structure, but the trailing elevator cable of this structure, after frequently bending, conductor easily ruptures, and Signal transmissions is unstable; Typical circular optical cable adopts pe sheath simultaneously, and cable is harder not flexible, and useful life is short.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide a kind of long service life, and long-time use is also less likely to occur fracture, thus ensures the trailing elevator cable of network signal transmission stability.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide a kind of novel structure, the trailing elevator cable of the long-time inhibit signal transmission stability of energy and accuracy.
The technical solution used in the present invention is for this reason: the present invention includes pancake cable cover(ing), in cable cover(ing), core is established respectively in two ends, and in cable cover(ing), butterfly optical cable is established at middle part.
Described core comprises the control conductor being symmetricly set on two ends in cable cover(ing), and is symmetricly set on two ends in cable cover(ing) and is in signal core inside control conductor.
Described butterfly optical cable comprises optical fiber, and is arranged on the low-smoke halogen-free flame-retardant sheath of outer fiber.
Described control conductor comprises some control conductor conductors, and every root control conductor conductor peripheral hardware insulating barrier forms some cable cores, cable core peripheral hardware control conductor sheath.
Described signal core comprises some holding wire core conductors, the outer provided with shielding layer of every root holding wire core conductor, screen peripheral hardware signal core sheath.
Cable cover(ing) outer surface upper and lower sides is arranged with several triangular grooves.
Described signal core comprises some holding wire core conductors, the outer provided with shielding layer of every root holding wire core conductor, screen peripheral hardware signal core sheath.
Advantage of the present invention is: 1) adopt butterfly leading in cable, the construction of cable is flat, identical with trailing elevator cable shape (flat), when trailing elevator cable bends, butterfly light lead cable cable is stressed little, and optical cable and optical fibres can meet the requirement of elevator cable bend test useful life;
2) butterfly is adopted to draw cable of giving out light, Signal transmissions carrier is optical fiber, transport vehicle is very soft, and common grid line employing is that sub-thread soft copper silk is after bending, easy generation fracture, adopt optical fiber as Signal transmissions carrier, network signal Transmission can not be caused, ensure that the stability that network signal transmits;
3) butterfly leading in cable is adopted, this sheath adopts low-smoke halogen-free flame-retardant sheath, and ordinary optical cable adopts pe sheath, ordinary optical cable pe sheath is harder, and cable is not flexible, butterfly leading in cable low smoke and zero halogen sheath used, not only have good fire resistance, cable bend performance is good, more flexible than common optical cable, and the signal transmission of optical cable is more stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is control conductor conductor; 2 is control conductor insulating barrier; 3 is signal conductor screen; 4 is butterfly optical cable optical fiber; 5 butterfly optical cable low-smoke halogen-free flame-retardant sheaths; 6 is cable cover(ing).
Embodiment
The present invention includes pancake cable cover(ing) 6, in cable cover(ing) 6, control conductor is established respectively in two ends, and is arranged on the signal core be positioned at inside control conductor in cable cover(ing) 6, and in cable cover(ing) 6, middle part is provided with butterfly optical cable.
Described butterfly optical cable comprises optical fiber 4, and is arranged on the low-smoke halogen-free flame-retardant sheath 5 of optical fiber 4 outside.
Described control conductor comprises some control conductor conductors 1, and every root control conductor conductor 1 peripheral hardware insulating barrier 2 forms some cable cores, cable core peripheral hardware control conductor sheath.
Described signal core comprises some holding wire core conductors, the outer provided with shielding layer 3 of every root holding wire core conductor, screen 3 peripheral hardware signal core sheath.
The present invention can have the triangular groove of multiple symmetry further at the outer surface of trailing cable sheath 6, be beneficial to pressure when extenuating extrusion molding, thus avoids trailing elevator cable surface irregularity and centre position easily to play the partially thick shortcoming of drum.
