Description

Technical Field

[0001] The present invention relates to the technical field of elevator operation safety, and in particular to a real-time monitoring and fault warning device for elevator steel ropes. Background Art

[0002] With the acceleration of urbanization, elevators have become an indispensable vertical transportation tool in modern buildings. As the core component of elevator operation, elevator wire ropes bear the huge pressure of elevator up and down transportation and are responsible for transmitting the lifting power of the elevator. However, due to long-term high-load and high-frequency working environment, problems such as aging, wear, and breakage of wire ropes gradually emerge. If not discovered in time, it may cause elevator failure or even serious safety accidents.

[0003] Traditionally, elevator wire rope fault detection mainly relies on manual inspection or regular inspection. Manual inspection cannot achieve 24-hour real-time monitoring, and it is difficult for inspectors to fully detect potential hidden dangers in wire ropes, such as small cracks, wear or excessive stretching. Although regular inspections can detect some faults, due to the long inspection cycle, they can usually only be repaired after the fault occurs, resulting in the elevator's safety hazards not being dealt with in a timely manner.

[0004] As one of the core transmission components of the elevator, the elevator wire rope bears a huge load for a long time. Any minor abnormality will affect the normal operation of the elevator and even cause a safety accident. At present, most elevators are not equipped with an effective wire rope fault monitoring system, resulting in many potential faults not being discovered in time. Therefore, the development of an efficient, real-time and intelligent monitoring system is of great significance to improving the safety of elevators. Summary of the invention

[0005] The purpose of the present invention is to provide an elevator wire rope real-time monitoring and fault warning device which realizes real-time monitoring of the wire rope status and early warning of hidden dangers by integrating a sensor module, a data processing module and a communication module, thereby improving the safety of elevator operation and the maintenance efficiency, and effectively solves the problems raised in the above-mentioned background technology.
