The invention relates to a tension difference adjusting method for first ropes of an elevator, the elevator comprises a plurality of first ropes arranged at intervals and containers arranged at the two ends of the first ropes respectively, a plurality of oil cylinders are arranged on the containers, the two ends of each first rope are each connected with one oil cylinder, and the tension difference adjusting method comprises the steps that the oil pressure of the oil cylinders is adjusted, adjusting the lengths of the plurality of first ropes to enable the oil pressure difference value among the plurality of oil cylinders to be smaller than a first threshold value p1, and adjusting the lengths of the plurality of first ropes to enable the length difference value of the plurality of first ropes to be smaller than a second threshold value lz. The length of the multiple first ropes and the oil pressure of the oil cylinder are adjusted, so that the tension of the multiple first ropes is adjusted, the tension difference among the multiple first ropes is reduced, the operation requirement of the elevator is met, operation is stable, safe operation of equipment is guaranteed, the equipment accident occurrence probability is reduced, and the equipment maintenance and repair operation cost is reduced.

    本公开涉及一种提升机首绳的张力差调节方法,提升机包括多个间隔设置的首绳和分别设置在首绳两端的容器,容器上设置有多个油缸,每个首绳的两端分别连接一个油缸,张力差调节方法包括:调整多个油缸的油压,以使多个油缸之间的油压差值小于第一阈值p1,和调整多个首绳的长度,以使多个首绳的长度差小于第二阈值lz。调整多个首绳的长度以及油缸的油压,从而调整多个首绳的张力,减小多个首绳之间的张力差,满足提升机运行要求,运行平稳,保障设备安全运行,减少设备事故发生概率,以降低设备维护、保养、维修运行成本。
