The invention relates to a working method of a multifunctional tower crane system integrated with an electric grab bucket, and belongs to the technical field of grab buckets of tower cranes. The tower crane system comprises a rotary platform, an electric grab bucket, a coil winder, a tower crane lifting hook, a display screen, a programmable controller and four operation keys installed in a cab. When the tower crane works and the tower crane function is used, the electric grab bucket is not used, and the electric grab bucket is hung below the rotary platform; when the grab bucket function is used, a tower crane lifting hook moves to a lifting ring to lift out the grab bucket, meanwhile, a cable connected with the electric grab bucket is released through buttons, and a driver controls a winding drum to rotate through two buttons in a cab and controls opening and closing of the grab bucket through a steel wire rope driving structure. The opening and closing limit positions are transmitted to the PLC through limiting and are displayed on the display screen to prompt a driver. The electric grab bucket is reasonable in structural design, safe, reliable, convenient to operate and intelligent, the electric grab bucket function is added, and the use requirement is met.

    本发明涉及一种集成电动抓斗的多功能塔机系统的工作方法,它属于塔机的抓斗技术领域。本发明塔机系统包括回转平台、电动抓斗、卷线机、塔机吊钩、显示屏、可编程控制器和安装在驾驶室的四个操作按键。本发明工作时,使用塔机功能时,电动抓斗不使用,该电动抓斗挂于回转平台下方;当使用抓斗功能时,塔机吊钩移动至吊环出吊出抓斗,同时通过按钮放出电动抓斗连接的电缆,驾驶员通过在驾驶室的两个按钮控制卷筒转动并通过钢丝绳带动结构控制抓斗的打开闭合,打开和闭合极限位置通过限位传输给PLC并在显示屏显示提示驾驶员。本发明结构设计合理,安全可靠,增加电动抓斗功能,操作方便,智能化,满足使用需求。
