Embodiment 1

[0037] Embodiment 1: A high safety factor elevator cable

[0038] See attached figure 1 As shown, a flat elevator cable with a high safety factor includes a flat outer sheath 1, and the outer sheath 1 covers a safety protection layer 2, an inner sheath 3, a combined cable core 4 and a load-bearing Element 5. The outer sheath 1 is extruded on the outside of the safety protection layer 2 in the shape of a flat thin tube; the safety protection layer 2 is a composite coaxial structure; the inner sheath 3 is extruded on the composite cable core 4 and the load-bearing element 5 outside. The combined cable core 4 includes at least one set of control cable units; the load-bearing elements 5 are arranged symmetrically side by side outside the combined cable core. The outer sheath 1 is a complex of fluororubber and antibacterial and rodent repelling drugs, and the antibacterial and rodent repelling drugs are evenly dispersed in the fluororubber. Silver 1.0% (mass percentage), copper...

Abstract

The invention provides an elevator cable with a high safety factor. A sheath of the elevator cable comprises an outer sheath, a safety protection layer and an inner sheath, wherein the raw material formula of the outer sheath contains 0.5-5wt% of antibacterial ratproof drug components; and the matrix resin of the outer sheath is fluororubber. In the invention, the high safety factor operating condition is provided in the aspect of non-electrical property design capability, so the elevator cable is suitable for working continuously and uninterruptedly in any extremely harsh environment.

Description

technical field [0001] The invention relates to an elevator cable, in particular to an elevator cable with a high safety factor. Background technique [0002] In the process of adapting to modernization, elevator cables have been continuously improving design and manufacturing technology. On the basis of early power control technology, signal control, wired communication, high-speed network, laser technology, etc. have been gradually developed. Every new technology The introduction of elevators has promoted a leap in elevator functions. After researching the technical details of elevators vertically and horizontally, it is found that when people design cables, they often unconsciously focus on electrical performance, such as mechanical, physical, chemical, biological, environmental, anti-destructive, etc. Other non-electrical aspects have paid less attention. Although under normal circumstances, the cable can basically realize the functions of energy transmission and signa...
