Problems solved by technology

Such elevator door machine cables are usually hard, with too many bends and easy to break
In addition, because there is no strong tensile core, the cable is easily broken when the elevator door machine is frequently switched left and right.

Abstract

Disclosed is a cable for a lift door. The cable comprises cable cores, a pull tension cotton yarn cord and a soft jacket. The cable is characterized in that the cable cores are provided with twisted soft conductors; the pull tension cotton yarn cord is arranged between the two cable cores which are spirally wound on the pull tension cotton yarn core. The conductors inside the leads are soft brasswire strands and the soft brass wires are coated with insulating barriers. The pull tension cotton yarn core is composed of four strands of twisted cotton yarn and each cotton yarn strand is composedof a plurality of twisted cotton yarn threads. The jacket is wrapped on the cable cores through half-extrusion. The cable for a life door is soft, and since the leads are spirally wound, the cable isof tensile resistance and is long in service life and good in effect.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable for an elevator door machine. Background technique [0002] The elevator is an indispensable means of transportation in high-rise buildings. It needs to move up and down frequently, and the cable that provides the working power for the elevator must also move up and down with it. With the development of technology and the needs of people's work and life, the elevator Some activities such as communication and monitoring are also required in the interior. For this reason, the relevant signal lines must be suspended next to the elevator, and the elevator is repeatedly lifted and lowered. 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 movement, there may be breakage, damage, resulting in power failure or other related problems. Consequences of Disruption of Fun...
