目前在对电梯的检测过程中,是通过用拉力计横向拉开钢丝绳的方式来得到其曳引力的偏差。这种方法精度低,而且人为操作因素大。在此引进一种新的测量方法,该方法利用应变片随自身伸长而增大电阻值的原理来求得钢丝绳所受张力的变化量,再利用电梯自身曳引的特性导出对钢丝绳所受张力求解的公式。进而得到钢丝绳张力的大小以及每根钢丝绳所受力的偏差。 At present, in the process of detecting the elevator, the deviation of the traction force is obtained by pulling the wire rope transversely with a tension meter. The accuracy of this method is low, and human factors are large. A new measurement method is introduced here. The method uses the principle that strain gauges increase their resistance as they elongate to obtain the change in the tension of the rope, and then uses the characteristics of the elevator itself to derive the resistance to the rope. Tension solution formula. In addition, the tension of the steel wire rope and the deviation of the force applied to each steel wire rope are obtained.
