The invention relates to the technical field of cranes, in particular to a closed-loop anti-swing control method of a crane, comprising transversely and symmetrically arranged sliding grooves and a lifting hook for lifting articles, the sliding grooves are vertically and slidably provided with the same portal frame, and the top of the lifting hook is provided with a lifting rope connecting piece; the top of the portal frame is provided with a trolley assembly used for controlling a lifting hook to move horizontally, the lower portions of the two ends of the portal frame are each provided with a first driving motor used for controlling the portal frame to move, the bottom of the portal frame is provided with a mounting base, mounting plates are vertically and symmetrically arranged at the bottom of the mounting base, and the same rotating shaft is transversely and rotationally inserted into the mounting plates. A winch assembly used for controlling the lifting hook to ascend and descend is arranged on the peripheral face of the rotating shaft, and second sliding sleeves are transversely and symmetrically arranged on the two sides of the mounting base. The output end of the electric push rod applies reverse thrust to the top plate to control the lifting rope connecting piece to move reversely, so that the lifting rope connecting piece is prevented from shaking, the shaking frequency is greatly reduced, used parts are simplified, and later maintenance is facilitated.

    本发明涉及起重机技术领域,具体涉及一种起重机闭环防摇控制方法,包括横向对称设置的滑动槽以及用于起重物品的吊钩,所述滑动槽竖向滑动设有同一龙门架,所述吊钩顶部设有吊绳连接件,所述龙门架顶部设有用于控制吊钩水平运动的小车组件,所述龙门架两端下部均设有用于控制龙门架运动的第一驱动电机,所述龙门架底部设有安装座,所述安装座底部竖向对称设有安装板,所述安装板横向转动插设有同一转轴,所述转轴外周面设有用于控制吊钩升降的卷扬组件,所述安装座两侧横向对称设有第二滑套。本发明通过设置的电动推杆输出端向顶板施加反推力控制吊绳连接件反向运动,从而防止其晃动,大大降低晃动频率,并且简化使用零件,便于后期维护。
