Multi-functional composite type elevator trailing cable

Abstract

The invention relates to a multi-functional composite type elevator trailing cable, which comprises an elevator trailing cable body consisting of a non-metal extrusion body and a cable arranged in theextrusion body, and is characterized in that: the elevator trailing cable body is provided with a plurality of bunches of tensile steel wires, a bunch of video communication cables, a bunch of telephone traffic communication cables, a bunch of audio transmission cables, a bunch of lighting cables, a bunch of Internet communication cables, a bunch of mobile communication cables, a plurality of bunches of elevator control wires and a plurality of spare cables. The multi-functional cable is arranged in the prior elevator trailing cable; therefore, the number of the cables in an elevator hoistwayis reduced greatly, elevators are overhauled conveniently, resources are saved simultaneously, the operation of an elevator is convenient greatly, and the operation safety of the elevator cable is ensured simultaneously.

Description

technical field [0001] The invention relates to the technical field of elevator cables, in particular to a multifunctional composite elevator accompanying cable. 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.

[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

In addition, the faster the elevator speed, the greater the wind resistance of the cable. In order to ensure the safe operation of the cable, the elevator can only run in a relatively low speed range, which affects work efficiency.

[0003] The general elevator communication adopts parallel communication technology, and the data of parallel communication must be sent and received at the same time, which requires that each communication unit must have two signal lines, so if the elevator floor is high, there will be many cables for parallel communication. The up and down of the elevator is inconvenient and affects the running speed of the elevator. If it is necessary to install voice devices in the elevator, such as speakers, emergency call telephones, etc., these must be equipped with corresponding cables to communicate with the outside world. The cost of installing these cables separately is high. The safety performance is poor, as the elevator is running, the cable is easily broken and damaged, making the equipment in the elevator unusable
