Tension detection device for elevator wire rope

Abstract

The invention discloses a tension detection device of a steel wire rope of an elevator. The tension detection device comprises a regulating device and a pressure sensor. One end of the regulating device is arranged on the pressure sensor. Through holes are formed in the regulating device and the pressure sensor respectively so that a rope end combination can penetrate through the through hole in the regulating device and the through hole in the pressure sensor. The pressure sensor can sense the pressure on the other end of the regulating device. The height of the regulating device can be regulated in the direction of the center line of the through hole in the regulating device. Due to the scheme, the tension on the steel wire rope can be directly measured, and the accuracy is high. The regulating device can be used for regulating the pre-pressure on the pressure sensor, so that when multiple steel wire ropes are measured, the end of each steel wire rope is provided with the tension detection device of the steel wire rope of the elevator. Therefore, the pre-pressures on the pressure sensors on the tension detection devices of all the steel wire ropes of the elevator are consistent, and the accuracy of detecting the tension on each steel wire rope can be improved.

Description

technical field [0001] The invention relates to a tension detection device of an elevator steel wire rope, in particular to a tension detection device of an elevator steel wire rope which can detect the tension of the elevator steel wire rope installed on the elevator with high precision. Background technique [0002] At present, elevators at home and abroad usually use a traction machine to drive the elevator. The suspension hoisting system of the traction elevator is composed of main components such as a traction sheave, a wire rope set, a car, and a balance weight system; The friction force generated by each steel wire rope in the traction wheel winding in the groove of the traction wheel provides the power to lift or lower the car; under the adjustment of the continuous development of elevator drive technology, the lifting height and driving speed of the elevator have greatly improved. At the same time, it also puts forward higher requirements for the safety and reliabil...

AI Technical Summary

Problems solved by technology

Therefore, the steel wire rope with high force that has been used for a long time is easy to break during use, causing elevator safety accidents; , will also cause the breakage of the steel wire rope, resulting in elevator safety accidents; in order to avoid elevator safety accidents, the elevator needs to be inspected every year for safety. The detection accuracy of this method is not high
