Online monitoring and alarming system, method and device for elevator steel wire rope

Abstract

The invention provides an elevator steel wire rope online monitoring alarm system, method and device. The system comprises a plurality of terminating devices, a plurality of annular pressure sensors, a data acquisition device, a data transmission device, a cloud platform server and a mobile terminal. Each end connecting device is respectively fixed on each steel wire rope, each end connecting device comprises a screw rod and an elastic element sleeved on the screw rod, and each annular pressure sensor is sleeved on each screw rod and is fixed on the elastic element corresponding to each screw rod; the data acquisition device is connected with the plurality of annular pressure sensors and is used for acquiring tension data of each steel wire rope; the data transmission device is respectively connected with the data acquisition device and the cloud platform server; the cloud platform server receives the tension data of each steel wire rope and analyzes whether the safety performance parameters of the elevator steel wire ropes are in a normal range or not; the mobile terminal is connected with the cloud platform server and used for receiving the safety performance parameters of the elevator steel wire rope in real time.

Description

technical field [0001] The present application relates to the technical field of elevators, and in particular, to an on-line monitoring and alarming system, method and device for elevator wire ropes. Background technique [0002] With the continuous development of the economy and the continuous expansion of the scale of the city, the heights and floors of buildings such as residences, hotels, and office buildings are increasing, and the number of elevators installed and used is also increasing. While the use of elevators brings convenience to people entering and exiting high-rise buildings, it has also received more and more attention due to the serious negative impact caused by elevator failures. Therefore, how to effectively monitor the safe operation of elevators and eliminate hidden dangers of various elevator failures in time has become an important issue that needs to be solved urgently by elevator production units, user units, and special equipment safety supervision ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are devices on the market for measuring the tension of elevator steel wires, which are offline detection or need to be installed on site, and generally only measure a single steel wire rope, which cannot accurately reflect the force of each steel wire rope. If each steel wire rope is measured Measurement requires a lot of manpower and time; for the load detection of the elevator car, it is generally detected by the overload switch at the bottom of the car, the pressure sensor of the wire rope head plate, or the tension of the wire rope, and the measurement accuracy is low or the measurement process is time-consuming and laborious. The situation; the method of testing the elevator balance coefficient is generally the weight loading method or the no-load measurement method. The results of this method are time-sensitive. Changes occur, but the maintenance personnel fail to check in time, that is to say, the actual state after the measurement is different from the state at the time of the measurement. Whether the balance coefficient becomes smaller or larger, it will affect the safe operation of the elevator

That is to say, the technical solutions in the prior art can only reflect the data when the maintenance personnel check, and cannot judge and process the changed data in time, and the real-time performance of the data is low
