Multifunctional high-rise high-speed elevator traveling cable with super-five-category unshielded twisted pair (UTP)

Abstract

The invention discloses a multifunctional high-rise high-speed elevator traveling cable with a super-five-category unshielded twisted pair (UTP), and relates to the field of cable structures. The multifunctional high-rise high-speed elevator traveling cable with the super-five-category UTP comprises a reinforcing core steel rope which is arranged at the center, wherein a steel rope protective cover wraps the periphery of the reinforcing core steel rope, a reinforcing core cotton yarn woven layer is arranged on the periphery of the steel rope protective cover, a power line core layer is arranged on the periphery of the reinforcing core cotton yarn woven layer, and a signal line layer is arranged on the periphery of the power line core layer. The signal line layer comprises ten pair-twisted shielding signal lines, a coaxial radio frequency cable and the super-five-category UTP. A control line core layer is arranged on the periphery of the signal line layer. First cable fiber filling materials are arranged between the power line core layer and the signal line layer. Second cable fiber filling materials are arranged between the signal line layer and the control line core layer. Third cable fiber filling materials are arranged at intervals among all control line cores in the circumferential direction. A cable core cotton yarn woven layer is arranged on the periphery of the control line core layer. An outer protective cover is arranged on the periphery of the cable core cotton yarn woven layer. The multifunctional high-rise high-speed elevator traveling cable with the super-five-category UTP is large in cable tensile strength and small in wind drag during operation and enables an elevator to run safely at a high speed.

Description

technical field [0001] The invention relates to the structural field of cables, in particular to a special cable for elevators. Background technique [0002] With the emergence of a large number of high-rise buildings, high-rise high-speed elevators are widely used. The cables of this kind of elevators also have their special requirements. They need to have good tensile strength, can withstand multiple bending, and have small signal transmission distortion. In the prior art, There is a high-rise high-speed elevator cable, which is mainly composed of control lines, radio frequency lines, signal lines and protection, reinforcement and other components. In addition, because 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. Contents of the invention [0003] The purpose of the present invention is to overcome ...
