The invention discloses an anti-swing device of a crane grab bucket, which comprises a mounting platform fixedly arranged on a crane, a lifting winding assembly arranged on the top surface of the mounting platform and used for lifting the grab bucket, and an opening and closing winding assembly arranged on the top surface of the mounting platform and used for controlling opening and closing of the grab bucket, and further comprises a multi-stage synchronous telescopic rod, one end is fixedly arranged at the bottom of the mounting platform; the positioning sleeve is fixedly arranged at the telescopic end of the multi-stage synchronous telescopic rod; the positioning column is fixedly arranged at the top of the grab bucket and is in insertion fit with the positioning sleeve; and the first driving assembly is fixedly arranged on the top surface of the mounting platform, is in transmission connection with the lifting winding assembly and is used for driving the multi-stage synchronous telescopic rod and the lifting winding assembly to synchronously ascend and descend. And the positioning column is inserted into the positioning sleeve at the telescopic end of the multi-stage synchronous telescopic rod, so that the grab bucket and the multi-stage synchronous telescopic rod form a flexibly connected whole, and the swing limiting effect on the grab bucket is achieved.
本发明公开了一种行车抓斗的防摇摆装置,包括:固定设置在行车上的安装平台、设置在所述安装平台顶面用于升降抓斗的升降卷绕组件和设置在所述安装平台顶面用于控制抓斗开合的开合卷绕组件,还包括:多级同步伸缩杆,一端固定设置在所述安装平台的底部;定位套筒,固定设置在所述多级同步伸缩杆的伸缩端;定位柱,固定设置在抓斗顶部并与所述定位套筒插接配合;第一驱动组件,固定设置在所述安装平台顶面并与所述升降卷绕组件传动连接,用于驱动所述多级同步伸缩杆与所述升降卷绕组件同步升降。定位柱插设在多级同步伸缩杆伸缩端的定位套筒中,使抓斗与多级同步伸缩杆之间形成一个柔性连接的整体,形成对抓斗摆动限位作用。
