The invention discloses a control method for a steel wire rope compensation device of a hoisting mechanism, which comprises the following steps of: setting three working conditions: under the working condition 1, analyzing data of two load sensors of the same fixed pulley block 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, R1-R2 is less than or equal to 1 (0 < = 1 < = G/2), the total load G of the steel wire rope acting on the single fixed pulley block is equal to the tensile force of the single steel wire rope * the number of pulley pieces of the fixed pulley block * 2), and 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), an alarm is given, and the hoisting mechanism stops working. According to the method disclosed by the invention, the compensation device limiter is arranged through the hoisting mechanism of the crane, so that stable and efficient operation of the system is further ensured, the safety and reliability of equipment are improved, and a direction is pointed for subsequent product design.
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:设置三种工况,在工况1下:分析同一定滑轮组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,则作用于单个定滑轮组上的钢丝绳总载荷G=单根钢丝绳拉力×定滑轮组滑轮片数量×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),则报警,起升机构停止工作。本申请公开的方法通过起重机起升机构设置补偿装置限制器进一步保证了系统稳定高效运行,提高设备安全性、可靠性,为后续产品设计指明了方向。
