The invention provides a crane lifting rope position calibration method and system and a crane, and the crane lifting rope position calibration method comprises the following steps: S10, lifting a lifting hook to a cut-off action position of an anti-overwinding switch, enabling the lifting hook to stop moving, and obtaining the length LA of a lifting rope between a winch and the lifting hook in a current state; s20, according to the LA, the number NA of remaining winding turns and/or the number NB of remaining unwinding turns of the hoisting rope on the winch in the current state are/is calculated; and S30, according to the NA and/or the NB, the number of remaining turns of the lifting rope and/or the number of unrolling turns of the lifting rope in the current state are/is calibrated for a lifting rope position sensor on the winch. According to the crane lifting rope position calibration method, the lifting rope on the winch does not need to be completely released, the operation steps and the calibration mode are simplified, the consumption of manpower and material resources is reduced, the calibration cost is saved, and the operation is safer.
本发明提供一种起重机吊绳位置标定方法及系统和起重机,该起重机吊绳位置标定方法包括:S10:将吊钩起升至防过卷开关的切断动作位置,使吊钩停止运动,获取当前状态下卷扬与吊钩之间的吊绳的长度LA;S20:根据所述LA,计算当前状态下卷扬上吊绳的剩余卷绕圈数NA和/或放卷圈数NB;S30:根据所述NA和/或所述NB,对卷扬上的吊绳位置传感器标定当前状态下的吊绳剩余圈数和/或吊绳放卷圈数。该起重机吊绳位置标定方法无需将卷扬上的吊绳全部放出来,简化了操作步骤和标定方式,减少人力物力的耗费,节约了标定成本,而且操作更加安全。
