Steel wire rope monitoring device applied to active safe elevator

Abstract

The invention discloses a steel wire rope monitoring device applied to an active safe elevator. In an operation process of the elevator, geometry acquisition, pulling force value measurement, tensionmeasurement and balance coefficient measurement are separately performed on the appearance of steel wire ropes through a flaw detection module, a pulling force detection module, a tension detection module and a balance coefficient detection module; then data is sent to an information collection unit for identification; then the data is sent to a calculation processing unit for calculation of a corresponding preset program after identification is finished; when calculation results of geometry image comparison, pulling force, tension and balance coefficients exceed preset values, the calculationprocessing unit transmits a signal to an abnormality alarming unit; the abnormality alarming unit transmits a signal to a terminal APP for alarming prompting in a wireless signal transmission mode; aworker is reminded to perform failure clearing off according to the corresponding alarming information in time; and therefore, safety of the elevator is greatly improved.

Description

technical field [0001] The invention belongs to the field of active safety elevators, and in particular relates to a wire rope monitoring device applied to active safety elevators. Background technique [0002] With the development of the economy, there are more and more elevator apartments in the city. In recent years, there have been frequent occurrences of elevator safety accidents. In the final analysis, there are two main reasons for such problems. The first is that the elevator system itself is defective, and the second is that the professional quality of the maintenance personnel is uneven. [0003] In the inspection of the elevator, the performance inspection of the elevator wire rope is one of the required inspection items. During the operation of the elevator, the performance of the elevator wire rope itself will be aged and worn, which will cause the elevator wire rope to break and wear.

Problems solved by technology

[0003] In the inspection of the elevator, the performance inspection of the elevator wire rope is one of the required inspection items. During the operation of the elevator, the performance of the elevator wire rope itself will be aged and worn, which will cause the elevator wire rope to break and wear. The operation of the elevator creates safety hazards, and there are generally multiple elevator wire ropes, which pull the elevator to move. During the operation of the elevator, the tension and tension on each wire rope are required to be even. If the tension gap is too large, it is easy to cause aggravated wear of the steel wire rope and cause safety hazards; the balance coefficient of the elevator determines the stability of the elevator operation. When the value of the balance coefficient of the elevator is inappropriate, it will affect the overall operation of the elevator and cause safety hazards. In view of the above problems, it is necessary to carry out regular inspection and maintenance of the elevator. Now most elevator management companies carry out the inspection and maintenance of the elevator through manual shutdown, which requires a lot of manpower and material resources. The inspection work is very cumbersome. Each working area of ​​the elevator is checked. This method of manual shutdown inspection cannot detect the real-time data of the elevator, and the real-time operation of the elevator cannot be known. Therefore, this method of regular manual inspection and maintenance still cannot guarantee the elevator in operation. It is absolutely safe, and at the same time, it is easy to cause elevator failure due to incomplete manual investigation or work mistakes. Therefore, an active and safe elevator monitoring device is needed to monitor the real-time operation data of the elevator.
