The invention relates to the technical field related to hoisting, in particular to a crane anti-swing device which comprises a first mounting frame, a second mounting frame and at least three connecting rods for connecting the first mounting frame and the second mounting frame; a spherical connecting piece is arranged between the first mounting frame and the second mounting frame, one end of the spherical connecting piece is fixedly connected with a gripper connecting rod penetrating through a through groove formed in the second mounting frame, and the gripper connecting rod is further hingedto the second mounting frame through at least three elastic telescopic assemblies; a movable piece is fixed to the other end of the spherical connecting piece and connected with counterweight assemblies installed on the connecting rods in a sliding mode; and the arranged counterweight assemblies are matched with movable rods so as to achieve a certain anti-swing effect on the gripper connecting rod, gravity separation is adopted, the phenomenon that the restoring cannot be achieved due to the adoption of an elastic structure is effectively avoided, and practicability is high.
本发明涉及吊装相关技术领域,具体是一种吊车防摆装置,所述吊车防摆装置包括第一安装架和第二安装架及连接所述第一安装架及第二安装架的至少三个连接杆;所述第一安装架及第二安装架之间设置有球型连接件,所述球型连接件的一端与贯穿所述第二安装架上设置的通槽的抓具连接杆固定连接,所述抓具连接杆还通过至少三个弹性伸缩组件与所述第二安装架铰接;所述球型连接件的另一端固定有活动件,所述活动件与滑动安装在所述连接杆上的配重组件连接。设置的配重组件配合活动杆,进一步对抓具连接杆起到的一定的防摆作用,采用重力远离,有效的补充了采用弹性结构带来的无法复原现象,实用性强。
