Problems solved by technology

[0003] (1) For the detection and adjustment of the tension force of the steel wire rope, it is only possible to detect and adjust the tension force of the steel wire rope during installation, irregular maintenance or regular maintenance. Damage caused by unbalanced tension has occurred;
[0004] (2) During installation, maintenance and maintenance, the conventional method of testing the tension force of steel wire ropes is to use expensive special instruments or spring balance stretching methods with low precision, or even rely on visual inspection and hand feeling

Embodiment 1

[0026] like figure 1 As shown, the present invention relates to an elevator wire rope tensioning force online detection system, including a cloud server 1, a sensor 7, a handheld monitor 17, an intelligent decision-making terminal 4 and an elevator system; the elevator system in the detection system and the traditional elevator system The same, including the hoistway 3, the intelligent decision-making terminal 4, the counterweight 8, the car 9, the traction wire rope 10, the movable pulley 11, the rope groove 12, and the wire rope head fixing plate 13. The improvement lies in:

[0027] Sensors 7 are respectively installed on the rope heads A14 and B15 of the rope heads on both sides of the traction wire rope 10 for sensing the tension of the two rope heads;

[0028] The sensor 7 is provided with an information collection board 16, which collects the tension force data induced on the sensor 7 and displays it on the display screen of the sensor 7 in real time; the sensor is conn...

Embodiment 2

[0036] like figure 1 As shown in the figure, an on-line detection system for elevator wire rope tensioning force involved in the present invention includes a cloud server 1, a sensor 7, a handheld monitor 17, an intelligent decision terminal 4 and an elevator system; its basic structure is the same as that of the first embodiment, but different The point is that the sensor 7 is separately arranged at the wire rope head A14 to detect the tension data at the wire rope head A14.

Embodiment 3

[0038] like figure 1As shown in the figure, an on-line detection system for elevator wire rope tensioning force involved in the present invention includes a cloud server 1, a sensor 7, a handheld monitor 17, an intelligent decision terminal 4 and an elevator system; its basic structure is the same as that of the first embodiment, but different The point is that the sensor 7 is separately arranged at the wire rope head B15 to detect the tension data at the wire rope head B15.

Abstract

The invention discloses a real-time on-line detection system for tension of a steel wire rope for an elevator. The detection system comprises a cloud server, a sensor, an information collection board, an intelligent decision-making terminal, a hand-held monitor and an elevator system, wherein the sensor monitors the tension for dragging the steel wire rope in real time and online displays a numerical value of the tension received by the steel wire rope, so that all the tension for dragging the steel wire rope is conveniently adjusted to be uniform, the service life of the steel wire rope is prolonged, and the elevator running comfortableness is improved; by monitoring the change of the numerical value of the tension for dragging the steel wire rope in real time, whether there are persons in a car can be determined, and a weighing function of the elevator is realized; the intelligent decision-making terminal receives data, makes a local decision according to set logic, and controls the elevator to emergently stop running or stop running after the elevator stops nearby in an abnormal state, thereby avoiding sudden accidents; and the cloud server collects historical big data, performs comparison, analysis, judgment and depicts a change trend of the tension of the steel wire rope, and if the trend becomes bad, a preventive and targeted maintenance service can be performed, thereby improving a safety coefficient of elevator running.

Description

technical field [0001] The invention relates to a detection system, in particular to an online real-time online real-time elevator wire rope tension force which can monitor the tension value of the end of a wire rope, perform data analysis according to the tension force value, control elevator operation, and predict and prompt detection and maintenance. Detection Systems. Background technique [0002] As an integral part of the traction system, the traction wire rope is an important suspension device for modern elevators. On the traction sheave and the guide wheel, the traction machine drives the traction sheave to rotate, and the traction force is generated by the friction between the traction wire rope and the traction sheave, so as to realize the lifting movement of the car and the counterweight, and achieve the purpose of transportation. In order to ensure safety, in practical applications, multiple independent wire ropes work together in groups, and the tension balance...
