Abstract
The utility model discloses a circular elevator cable which has stable travelling and long free-hanging length, can be applicable to the elevator with high motion speed and has pair-twisted shielding signal wires; the circular elevator cable comprises a reinforced core steel rope which is positioned at the center of the cable; an inner jacket is arranged outside the reinforced core steel rope, an inner cotton braided layer is arranged outside the inner jacket; the periphery of the inner cotton braided layer is uniformly provided with eight insulated pair-twisted shielding signal bunches which circulate a core consisting of the reinforced core steel rope, the inner jacket and the inner cotton braided layer and are twisted with the same core; in addition, the circular elevator cable also comprises an outer cotton braided layer which wraps all the insulated pair-twisted shielding signal bunches; and an outer jacket is arranged outside the outer cotton braided layer.
Description
Technical field
The utility model belongs to the elevator cable technical field, relates in particular to a kind of circular elevator cable with the pair twist shielded signal wire.
Background technology
The core layout structure is unreasonable in the oversheath of existing circular elevator cable, and is not steady when cable moves with elevator, and the length that freely hangs of cable is lacked the elevator of the high speed of service of cable not applicable.
The utility model content
It is steady that technical problem to be solved in the utility model provides a kind of retinue, and it is long freely to hang length, applicable to the circular elevator cable of the band pair twist shielded signal wire of the elevator of the high speed of service.
The utility model comprises the strengthening core steel cable that is in cable center, at the arranged outside inner sheath of described strengthening core steel cable, and cotton braid in the arranged outside of inner sheath; The periphery of cotton braid arranges that equably eight thoroughly do away with edge pair twist shielded signal wire harness in described, and the fuse that described eight eradication edge pair twist shielded signal wire harness are formed around strengthening core steel cable, inner sheath and interior cotton braid is stranded with core; Also comprise outer cotton braid in addition with above-mentioned all insulation pair twist shielded signal wire harness parcels; The arranged outside oversheath of cotton braid outside described.
As improvement of the present utility model, between per two adjacent insulation pair twist shielded signal wire harness, fill a rope made of hemp respectively.
As further improvement of the utility model, every eradication edge pair twist shielded signal wire harness comprises that two of mutual pair twist thoroughly does away with the edge core, is wrapped in the restrictive coating that two of mutual pair twist thoroughly does away with the outer screen of edge core, is arranged on the described screen outside.
Compare with existing elevator cable, the strengthening core steel cable in the utility model can be strengthened the resistance to tension of elevator cable, make cable freely to hang length long and be applicable to the elevator of the high speed of service.The fuse that all insulation pair twist shielded signal wire harness are formed around strengthening core steel cable, inner sheath and interior cotton braid is stranded with core, makes the internal structure of cable rationally distributed, and is steady when cable moves with elevator.
The rope made of hemp is filled the rounding property of the pair twist shielded signal wire harness that can guarantee to insulate when stranded, and is tightr between the order insulation pair twist shielded signal wire harness.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, strengthening core steel cable 1 is in the center of cable, at the arranged outside polyvinyl chloride inner sheath 2 of described strengthening core steel cable 1, and cotton braid 3 in the arranged outside of polyvinyl chloride inner sheath 2.
The periphery of cotton braid 3 is arranged eight polyvinyl chloride insulation pair twist shielded signal wire harness 4 equably in described, and the fuse that described eight polyvinyl chloride insulation pair twist shielded signal wire harness 4 are formed around strengthening core steel cable 1, polyvinyl chloride inner sheath 2 and interior cotton braid 3 carries out stranded with core.Simultaneously, between per two adjacent polyvinyl chloride insulation pair twist shielded signal wire harness 4, fill a rope made of hemp 5 respectively.Outer cotton braid 6 is with above-mentioned all polyvinyl chloride insulation pair twist shielded signal wire harness 4 and the rope made of hemp 5 parcels.The arranged outside polyvinyl chloride oversheath 7 of cotton braid 6 outside described.
Preferably, every polyvinyl chloride insulation pair twist shielded signal wire harness 4 comprise mutual pair twist two polyvinyl chloride wire core 4-1, be wrapped in the outer screen 4-2 of two polyvinyl chloride wire core 4-1 of mutual pair twist, be arranged on the pvc sheath layer 4-3 in the described screen 4-2 outside.
The replaceable sheath of making for low smoke and zero halogen inner sheath, low smoke and zero halogen oversheath or other ep-type material of polyvinyl chloride inner sheath in the utility model, polyvinyl chloride oversheath.To be not limited to be polyvinyl chloride to the manufactured materials of insulating barrier in the every polyvinyl chloride wire core of polyvinyl chloride insulation pair twist shielded signal wire harness, and the also replaceable restrictive coating of making for low smoke and zero halogen restrictive coating or other ep-type material of the restrictive coating of polyvinyl chloride insulation pair twist shielded signal wire harness.
Claims (3)
1. be with the circular elevator cable of pair twist shielded signal wire, it is characterized in that: comprise the strengthening core steel cable that is in cable center, at the arranged outside inner sheath of described strengthening core steel cable, cotton braid in the arranged outside of inner sheath; The periphery of cotton braid arranges that equably eight thoroughly do away with edge pair twist shielded signal wire harness in described, and the fuse that described eight eradication edge pair twist shielded signal wire harness are formed around strengthening core steel cable, inner sheath and interior cotton braid is stranded with core; Also comprise outer cotton braid in addition with above-mentioned all insulation pair twist shielded signal wire harness parcels; The arranged outside oversheath of cotton braid outside described.
