Embodiment 1

[0062] A flat type elevator accompanying cable for super high-rise ultra-high-speed elevators, such as Figure 1-3 As shown, the flat sheath 11 is included, and 10 core units 12 and load-bearing elements 13 are arranged in a straight line in the flat sheath 11 .

[0063] The core unit 12 has a primary cabling structure. Select a cross-sectional area of ​​0.5mm 2 (20 / 0.18mm) 5 kinds of soft structure bundled copper wires are used as the conductor core 1, and the PE insulating material 2 is coated outside the conductor core 1 as the insulating core 3; a PVC is surrounded by 6 insulating cores 3 The core unit 12 is formed by stranding the filler core 4 in one stranding, the twisting direction of the stranding in the stranding direction is the same as that of the insulated core conductor strands, and the cabled pitch is 10-12 times the outer diameter of the core unit, which can be used The non-back-twisting equipment forms the cable, and the core pay-off tension is properly cont...

Embodiment 2

[0067] A flat type elevator accompanying cable for super high-rise ultra-high-speed elevators, such as Figure 4-5 As shown, including the flat sheath 21, there are 6 core units 22 and load-bearing elements 23 arranged in a straight line in the flat sheath 21, and there are 4 units in the middle of the core unit 22 in the flat sheath. TPS shielded pair composite optical cable 24.

[0068] The core unit 22 has a primary cabling structure. Select the cross-sectional area as 1.0mm 2 (40 / 0.18mm) 5 kinds of soft structure bundled copper wires are used as the conductor core, and the PE insulating material is coated outside the conductor core as the insulating core; it is composed of 6 insulating cores around a PVC lining core at one time. The cable is twisted to form a core unit 22. The twisting direction of the first cable is the same as the direction of the insulated core conductor bundle, and the cable pitch is 10-12 times the outer diameter of the core unit. It can be cabled w...

Abstract

The invention discloses a flat-type elevator traveling cable for a super-high-rise super-speed elevator. The flat-type elevator traveling cable comprises a flat-type sheath. An even number of cable core units and force-bearing units which are in linear arrangement are arranged in the flat-type sheath. The cable core units is in a once cabling structure and is formed by performing once cabling stranding on four, five, six, seven or eight insulation wire cores around one PVC filling and lining core, and then two, three or four once cabling wire core units are arranged into unit group wire cores; and when the unit group wire cores are arranged, the unit group wire cores are in axial symmetry with the center line of the flat type cable being the center based on the number of the insulation wire cores and cross section of conductors. The flat-type elevator traveling cable helps to solve the technical problems of the flat-type elevator traveling cable for the super-high-rise super-speed elevator and the present situation of the dependence on import; and after the flat-type cable is vertically hung, the torsion angle is small, and the dynamic balance degree and mobile stability are good.

Description

technical field [0001] The invention relates to a flat cable used in high-speed moving situations in a vertical state, especially relates to a high-speed elevator used in super high-rise buildings (over 100m in height) with a lifting speed of 4M / S to 12.5M / S. flat cable. Background technique [0002] The total number of cores of the accompanying control cables used in civil or commercial buildings with a building height of more than 100m is 40 cores or more. [0003] At present, with the development of the elevator industry, there are Japanese brands and European brands in elevators. However, in terms of high-speed elevators, since the overall elevator balance coefficient of Japanese elevators is quite different from that of European elevators, the flat elevator accompanying cables used in Japanese elevators for high-speed elevators all use flat accompanying cables with more than 90 cores and Above, the unit weight of the flat elevator accompanying cable is greater than 3....
