An anti-play mechanism for a cargo boom comprises a locking part and a gravity center adjusting part, the first end of the locking part is used for being rotationally connected with a knuckle arm, the second end of the locking part forms a hooking end, the gravity center adjusting part is fixedly connected to the side, away from the hooking end, of the locking part, and a balance weight piece is arranged on the gravity center adjusting part. The counterweight part can be movably arranged relative to the locking part so as to adjust the gravity center position of the locking part. According to the anti-movement mechanism of the cargo boom, the gravity center of the locking part moves on the two sides of the rotating center point of the locking part at different angles, the functions that the anti-movement mechanism is unhooked when the cargo boom is lifted, the cargo boom freely stretches out and draws back, and the anti-movement mechanism locks the telescopic joint arm when the cargo boom runs on a road are achieved, the structure is simple, operation is convenient and fast, and the service life is long. The invention further provides a cargo boom and a crane.
一种起重臂防窜动机构,包括锁止部和重心调节部,其中,锁止部的第一端用于与节臂转动连接,锁止部的第二端形成钩挂端,重心调节部固定连接于锁止部上远离钩挂端的一侧,重心调节部上设有配重件,配重件可相对锁止部移动地设置以调节锁止部的重心位置。该起重臂防窜动机构,通过不同角度时锁止部的重心在其转动中心点两侧的移动,实现起重臂起吊时防窜动机构脱钩、起重臂自由伸缩,道路行车时防窜动机构锁住伸缩节臂的功能,结构简单,操作便捷,使用寿命长。本发明还提供一种起重臂和一种起重机。
