The invention discloses a control method for a steel wire rope compensation device of a hoisting mechanism, which comprises the following steps of: respectively detecting load change signals of different hoisting mechanisms at the tail part of a winding drum by adopting two load sensors, and judging the load change condition of a steel wire rope; when the loads R1 and R2 of a left fulcrum and a right fulcrum are equal, namely R1-R2 is smaller than or equal to 1 (0 < = 1 < = G/2, and the total load G of the steel wire rope acting on the single winding drum is equal to the pull force of the single steel wire rope * 2), the hoisting mechanism is allowed to work normally; and when the load difference of the two fulcrums exceeds a deviation limit value, namely R1-R2 is greater than or equal to 2 (2 is greater than or equal to 0 and less than or equal to G), sending an alarm signal and controlling the hoisting mechanism to stop working.

    本发明公开了一种用于起升机构钢丝绳补偿装置的控制方法,包括:采用两个载荷传感器分别检测不同起升机构在卷筒尾部的载荷变化信号,并判断钢丝绳的载荷变化情况;分析不同卷筒尾部两个载荷传感器数据并判断钢丝绳的载荷变化情况:当左右两个支点的载荷R1、R2相等时,即|R1‑R2|≤△1(0≤△1≤G/2,作用于单个卷筒上的钢丝绳总载荷G=单根钢丝绳拉力×2),则允许起升机构正常工作;当两个支点载荷差超过偏差限值时即|R1‑R2|≥△2(0≤△2≤G),则发出报警信号并控制起升机构停止工作。
