Travelling cable for low-rise building elevator

Abstract

The scheme relates to a traveling cable for a low-rise building elevator. The traveling cable comprises: a first input connector, a first output connector and a main cable. The main cable has a circular or flat cross section. The main cable includes a sheath layer, a braid layer, a control wire layer, a shielding layer, a main wire layer and a steel wire sequentially from the outside to the inside, and further includes a filler. The main cable has a shape of an Archimedes spiral. The first input connector is disposed on the outer side of a disk-shaped main cable, and is fixed on the ground. The traveling cable for the low-rise building elevator of the invention is arranged in a disk shape at the bottom of an elevator car, during the movement of an elevator, the deformation quantity of eachpart of the traveling cable are controlled within a certain range, the traveling cable can have a greater design freedom in terms of tube diameter, internal pipeline material selection and overall weight, is lighter and thinner than ordinary traveling cables, and has advantages over ordinary traveling cables in terms of service life, occupied space and energy consumption.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an accompanying cable for elevators in low-rise buildings. Background technique [0002] With the continuous development of our country's economy, elevators are becoming more and more common in the development of cities in our country. [0003] The accompanying cables associated with elevators are also diversified, including elevator accompanying cables for video surveillance and elevator accompanying cables for digital networks. During the movement of the elevator, the cables are frequently bent and pulled, which affects the service life. Due to the complexity of the various lines, these lines have relatively poor tensile properties, and may break after a long period of frequent lifting movements. , damage, resulting in the consequences of power outage or other related function interruption; this phenomenon is most likely to occur at the lower floor end of the mos...

AI Technical Summary

Problems solved by technology

During the movement of the elevator, the cables are frequently bent and pulled, which affects the service life. Due to the complexity of the various lines, these lines have relatively poor tensile properties, and may break after a long period of frequent lifting movements. , damage, resulting in power outage or other related function interruption; this phenomenon is most likely to occur at the lower floor end of the most frequently used accompanying cables

[0004] In order to ensure that the accompanying cable has a sufficient service life, designers have to increase the diameter of various wires in the accompanying cable, or sacrifice some performance to improve the bending resistance of the wires, which not only increases the weight of the accompanying cable, but also makes the accompanying cable It takes more power to bend the cable when moving with the elevator

[0005] In addition, with the improvement of people's living standards, many villas, duplex houses, and low-rise businesses have the need to install elevators. Since the minimum bending radius allowed by the accompanying cable during installation and laying must not be less than 6 times the small side of the cable, it is necessary to The installation space, because the place where the elevator needs to be installed is often very expensive, this will undoubtedly increase the total cost of the elevator installation
