The invention discloses a portal crane boom sling cable drum cable control take-up and pay-off system, which comprises a cable drum, a cable control system, a cable control system and a cable control system, the cable drum is mounted at one end, provided with a sling, of a boom, a cable is arranged on the sling, one end of the cable is mounted on the sling cable drum, and take-up and pay-off of the cable are realized through rotation of the cable drum; the lifting absolute value encoder is used for measuring the lifting height of the lifting appliance; the variable amplitude measurer is used for measuring the rotation angle of the cantilever crane; and the reel controller is used for controlling the rotation direction of the cable reel and obtaining the adjustment data of the cable reel according to the data of the lifting absolute value encoder and the variable amplitude measurer. The winding drum controller comprises a winding and unwinding prediction module and a winding and unwinding control module, and the winding and unwinding prediction module is used for obtaining prediction data according to the current motion state and controlling the winding and unwinding control module to control the cable winding drum. The operation safety and efficiency of the crane are effectively improved, and the maintenance cost is reduced.

    本发明公开了一种门座起重机臂架吊具电缆卷筒电缆控制收放系统,包括:电缆卷筒,安装在臂架设置吊具的一端,所述吊具上设置有电缆,所述电缆一端安装在吊具电缆卷筒上,通过电缆卷筒转动实现电缆的收放;起升绝对值编码器,用于测量吊具起升高度;变幅幅度测量器,用于测量臂架转动角度;卷筒控制器,用于控制电缆卷筒转动方向,根据起升绝对值编码器和变幅幅度测量器的数据得到电缆卷筒的调整数据。卷筒控制器包括收放预测模块和收放控制模块,所述收放预测模块用于根据当前运动状态得到预测数据,并控制收放控制模块,对电缆卷筒进行控制。有效提高了起重机的作业安全性和效率,降低了维护成本。
