Description

Technical Field

[0001] The utility model relates to a high-strength anti-twisting flat high-speed elevator balancing cable. Background Art

[0002] The elevator cars used in high-rise buildings are much larger than ordinary ones. They are not only large in size, but also run very fast, so high-speed cables are used for control. However, because the weight of high-speed cables is much heavier than ordinary cables, this brings new problems to the counterweight of elevators. The use of heavier cables affects the balance of the elevator, so it is necessary to configure another cable at the other end of the car. Although this cable is a balanced cable, it also runs at high speed with the elevator, so ordinary balanced cables cannot be used. Therefore, a high-strength anti-twisting flat high-speed elevator balanced cable is proposed to address the above problems. Utility Model Content

[0003] The utility model aims to overcome the existing defects and provide a high-strength, torsion-resistant flat high-speed elevator balancing cable. The high-strength performance can meet the long-term operation of the cable, and the torsion resistance solves the stability of the high-speed operation of the cable, effectively improving the quality of the cable.

[0004] The technical solution to achieve the above purpose is: a high-strength torsion-resistant flat high-speed elevator balancing cable includes multiple cores, every six of the cores are twisted into a cable; multiple cores are twisted into six groups of cables, and the six groups of cables are covered with an outer sheath.

[0005] Preferably, every six of the wire cores are twisted into a cable, and a cable filler is arranged in the middle.

[0006] Preferably, every two of the six groups of cables are close to each other.

[0007] Preferably, the cable filler and the outer sheath are both made of PVC material.

[0008] The beneficial effects of the utility model are as follows: the high-strength anti-twisting flat high-speed elevator balancing cable has high-strength anti-twisting performance, which greatly reduces the deflection of the cable and ensures the normal operation of the cable. The high-strength performance can meet the long-term operation of the cable, and the anti-twisting performance solves the stability of the high-speed operation of the cable, effectively improving the quality of the cable. The convenient matching scheme also simplifies the product selection and meets the configuration needs of the elevator in many aspects. One or more configurations can be used to solve the balance problem. It can improve the balance of the elevator's counterweight, greatly expand the applicability of the cable, and support the use of various types of elevators. In addition to having strong anti-twisting performance and excellent operating performance, reducing the failure rate in use, it also has reliable bending resistance and oil resistance, extending the service life of the cable.
