Abstract
The invention relates to a railway signal emergency repair cable, which is to provide railway signal emergency repair cable with high screening, high flexibility, and repeated curving use. The invention includes at least a group of quads, an elastic cushion layer wrapping the quads, a woven screen layer wrapping the elastic cushion layer, and an external protection sleeve wrapping the woven screening layer; the quads includes twisted quad core and belting wrapping the quad core; the core includes soft core, elastic cushion belting wrapping each soft core, woven screen belting wrapping the elastic cushion belting, and polyester belting wrapping the woven screen belting.
Description
Technical field
The present invention relates to a kind of railway signal emergent salvaging cable.
Background technology
Mainly bear the track circuit of control train operation, message transmission task such as light a lamp along the railway signal cable of trackage overall length parallel lay-up.Owing to reasons such as construction, disasters, cause signal cable to interrupt sometimes, railway signal cable is in case interrupt, and will cause the train parking immediately or jeopardize the generation of accidents such as traffic safety.
Existing all kinds of railway signal cable, comprise that railway digital signal cable, inner shield signal cable, railway axle-counting signal cable, comprehensive shielded signal cable etc. generally are to design according to direct buried fixedly laying, the cable outside is enclosed with shielding protection layers such as aluminium sheath, armouring tape usually, generally greater than 25 times of cable size, bending radius is limited for Cable Bending Radius; Cable insulation cable core lead can reach 61 cores and make for single strand of copper wire, can not bear alternating bending and use.Therefore when interrupting appearred in signal cable, as the recovery that continues with similar cable, quantities was bigger, complicated operation, and the engineering time is long, has influenced the normal driving of railway.
Summary of the invention
The present invention has overcome the deficiency in the existing railway signal cable emergency first-aid repair technology, the road signal emergency salvaging cable that provides a kind of high shielding, high flexibility, energy alternating bending to use.
The present invention is achieved in that a kind of railway signal emergent salvaging cable, comprises at least one group of quad, is coated on the outer elastic cord breaker of described all quads, is coated on the outer woven shield of described elastic cord breaker, is coated on the outer oversheath of described woven shield; Described quad comprises four stranded core assembly lines and is coated on the outer band of described four core assembly lines; Described heart yearn comprises the flexible cord core, is coated on the outer insulating tape of each described flexible cord core, is coated on the outer braid shielded band of described insulating tape, is coated on the outer polyester band of described braid shielded band.
The material of described elastic cord breaker and described elastic buffer band is silicon rubber; Adopt the star quad stranding mode stranded between described many group quads; Described four core assembly lines in the described quad adopt that SZ is stranded in twos, and again that described two core assembly line SZ after stranded in twos are stranded mode is stranded.
Compared with prior art, advantage of the present invention is: the use of woven shield, braid shielded band has improved the cable antijamming capability of electromagnetism to external world greatly; The elastic cord breaker of silastic material, elastic buffer band both improved greatly cable flexibility, make cable can adapt to the requirement of alternating bending, also increased cable ageing resistance, improved the resistance to wear of cable.

Embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing and concrete execution mode:
Referring to Fig. 1, a kind of railway signal emergent salvaging cable comprises at least one group of quad 1, is coated on the outer elastic cord breaker 2 of described all quads 1, is coated on the outer woven shield 3 of described elastic cord breaker 2, is coated on the outer oversheath 4 of described woven shield 3.Adopt the star quad stranding mode stranded between described many group quads 1.
Referring to Fig. 2, described quad 1 comprises four stranded core assembly lines 11 and is coated on described four core assembly lines 11 band 12 outward.Described four core assembly lines 11 in the described quad 1 adopt that SZ is stranded in twos, and again that described two core assembly line SZ after stranded in twos are stranded mode is stranded.
Referring to Fig. 3, described heart yearn 11 comprises flexible cord core 111, be coated on the outer elastic buffer band 112 of each described flexible cord core 111, be coated on the outer braid shielded band 113 of described elastic buffer band 112, be coated on the outer polyester band 114 of described braid shielded band 113.
Described elastic cord breaker 2 and described elastic buffer band 112 adopt silastic material, both improved greatly cable flexibility, make cable can adapt to the requirement of alternating bending, also increased cable ageing resistance, improved the resistance to wear of cable.Described woven shield 3 and described braid shielded band 113 adopt stainless steel or copper wire material used, have improved the cable antijamming capability of electromagnetism to external world greatly.
Described each band 12 adopts different colours, and described each polyester band 114 in each described band 12 adopts different colours, is highly susceptible to during use discerning corresponding heart yearn 11, has improved railway signal cable emergency first-aid repair efficient greatly.
