The invention discloses a control method for a gantry crane container spreader. The control method comprises the steps that the inclination angle of a spreader structure body is obtained; judging whether the inclination angle is within a preset inclination angle range or not; if the inclination angle is not within the preset inclination angle range, obtaining an adjustment position and generating a moving signal; controlling the lifting appliance trolley to move to an adjusting position according to the moving signal; judging whether the inclination angle is within a preset inclination angle range or not; if yes, the lifting appliance trolley is controlled to stop; if not, the real-time position of the lifting appliance trolley is obtained, and then the inclination angle and the adjustment position are obtained again for adjustment; and if the real-time position is not the adjusting position, the lifting appliance trolley is controlled to move according to the adjusting signal. Therefore, the position of the lifting appliance trolley is adjusted according to the inclination angle, so that the levelness of the container is adjusted, the inclination angle is reduced, and the problems that a lifting appliance hydraulic system breaks down easily due to long-time operation, the service life is shortened due to uneven stress of a lifting appliance main body structure and a portal crane steel wire rope, and goods are damaged are solved.

    本发明公开了一种门机集装箱吊具的控制方法,获取吊具结构主体的倾斜角度;再判断倾斜角度是否与预设定倾角范围内;如果不在预设定倾角范围内,得到调整位置生成移动信号;根据移动信号,控制吊具小车移动至调整位置;再判断倾斜角度是否在预设定倾角范围内;如果在,控制吊具小车停止;如果不在,获取吊具小车的实时位置,再重新获取倾斜角度和调整位置,进行调整;如果实时位置不是调整位置,再根据调整信号控制吊具小车移动即可。可见,本发明根据倾斜角度调整吊具小车的位置,来调节集装箱的水平度,以减小倾斜角度,解决了偏重长时间作业易导致吊具液压系统故障,吊具主体结构及门机钢丝绳受力不均减少使用寿命,造成货损等问题。
