Description

Technical Field

[0001] The utility model relates to the technical field related to elevator cables, and in particular to a traveling flat structural cable for elevators. Background Art

[0002] Elevator traveling cables are professional cables used in elevator operation. There are elevator traveling cables for video surveillance and elevator traveling cables for digital networks. Elevators are indispensable transportation equipment in high-rise buildings and they move up and down frequently. The cables that provide working power for the elevators must also move up and down. Moreover, with the development of science and technology and the needs of people's work and life, some activities such as communication and monitoring are also needed in elevators.

[0003] After extensive searching, I found that the Chinese patent announcement number is CN220020684U, which discloses a flat elevator cable, including an outer sheath, several cable layers and several reinforcing core layers, wherein the several cable layers and the several reinforcing core layers are all located inside the outer sheath; reinforcing core layers are provided inside the outer sheath on both sides of the cable layer; the outer sheath includes a resistance layer and an elastic layer from the outside to the inside, and the resistance layer includes a wear-resistant layer and a thermal insulation layer from the outside to the inside; the cable layer includes a shielding layer, an insulating layer, a fireproof layer and a cable from the outside to the inside. The utility model can enhance the tensile strength of the cable body more evenly and ensure its service life by providing reinforcing core layers in the sheath units on both sides of the cable layer; the structural setting of the shielding layer can provide a double-layer shielding treatment for the cable layer, which has a better shielding effect than the previous single-layer metal shielding layer, further ensuring the normal use of the elevator.

[0004] In summary, in existing elevator cables, the tensile strength of the inner cable is improved by the reinforcing core layers on both sides. However, there is a certain distance between the reinforcing core layer and the inner cable, which limits the improvement of the structural strength of the inner cable by the reinforcing core layer.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a flat structural cable for elevators to make it more valuable for industrial use. Utility Model Content

[0010] The cable layer includes cables, insulation layers, reinforcement layers, heat-conducting layers, flame-retardant layers and protective structures from the inside to the outside.

[0011] As a further improvement of the present invention, the supporting braided structure is a mesh structure woven from a plurality of mutually intersecting metal wires.
