Kevlar fiber reinforced multifunctional travelling soft elevator composite cable

Abstract

The invention discloses a Kevlar fiber reinforced multifunctional travelling soft elevator composite cable and belongs to the technical field of a cable. The Kevlar fiber reinforced multifunctional travelling soft elevator composite cable comprises a sheath layer with a flat-shaped cross section, and power supply cables, audio transmission cables, illumination cables, communication cables and reinforced ribs which are arranged in the sheath layer. The audio transmission cables, the illumination cables, the communication cables and the power supply cables are successively arranged in the middle portion of the composite cable, the Kevlar fiber reinforced ribs are arranged at two sides, the audio transmission cables are composed of two audio lines, the conductors of the audio lines are twisted oxygen-free copper wires, and the audio transmission cables are externally provided with a protective layer; the power supply cables are formed by twisting two insulation wires, and the insulation lines are formed by extruding a PVC insulation layer on copper wire conductors; and the communication cables are composed of two communication wires, communication wire conductors are formed by extruding an insulation layer outside twisting soft cooper wires, and the illumination cables are composed of two illumination wires. The Kevlar fiber reinforced multifunctional travelling soft elevator composite cable is simple, reasonable and compact in structure, low in weight, easy to manufacture and produce, good in application performance and long in service life, and also has anti-high-interference, flexible and tensile properties.

Description

technical field [0001] The invention relates to an elevator cable structure, especially with signal transmission and telephone communication, and belongs to the technical field of cables. Background technique [0002] Elevators are essential means of transportation in high-rise buildings. Elevator cables are mainly used in frequently-moving elevators. The elevator room is a small, almost closed space. Half of the elevator cables are used for extension. High-rise elevators can Up to more than 100 meters, the weight of a 100-meter cable is nearly 100 kilograms, so the elevator cable needs to have a strong tensile capacity to ensure that the cable will not break during frequent movement, and its internal signal lines and power lines will not It will be disturbed by the external electric field and internal electric field of the cable. The existing elevator cables on the market often cannot meet the actual required tensile strength, the anti-interference ability of the signal li...

AI Technical Summary

Problems solved by technology

The existing elevator cables on the market often cannot meet the actual required tensile strength, the anti-interference ability of the signal line is not very strong, and when the power line has a fault such as a short circuit, it is often necessary to replace the entire elevator cable

These problems have affected the service life of elevator cables and increased the incidence of elevator accidents

Moreover, with the development of society, some activities such as communication are also required in the elevator. For this reason, related wires have to be hung beside the elevator, and they are repeatedly lifted and lowered together with the elevator. Frequent tension will affect the service life, and because the various lines are too complicated, and these lines are relatively poor in tensile performance, after a long period of regular lifting movements, they may break, damage, and cause power outages Consequences of suspension or other interruption of related functions
