The invention discloses a swing arm type lifting gravity center adjusting lifting beam which comprises a main beam body used for lifting a lifted object in a balanced mode, a front lifting structure is arranged at the front end of the bottom of the main beam body, a rear lifting structure is arranged at the rear end of the bottom of the main beam body, and the front lifting structure and the rear lifting structure are connected with the lifted object below through rigging and a rope; the bottom end of the swing arm is connected to the middle of the main beam body through a pin shaft, and the top end of the swing arm is provided with a lifting point structure connected with a lifting hook; and the push-pull unit can linearly extend or contract, a pin shaft at the working end of the push-pull unit is connected to the side wall of the swing arm, and a pin shaft at the bottom end of the push-pull unit is connected to the top face of the main beam body. The invention further discloses a working method of the swing arm type lifting gravity center adjusting lifting beam. According to the technical scheme, the swing arm is pushed and pulled to rotate along the rotating shaft, the left-right position of a hoisting point relative to the hoisting beam is changed to achieve stable hoisting, and meanwhile the hoisting state of a hoisted object can be adjusted.
本发明公开了一种摆臂式调整起吊重心吊梁,包括:主梁体,用于平衡起吊被吊物,所述主梁体底部前端设置前吊结构且后端设置后吊结构,所述前吊结构和后吊结构通过索具和绳缆连接下方的所述被吊物;摆臂,所述摆臂的底端销轴连接在所述主梁体中部,所述摆臂的顶端设置连接吊钩的起吊点结构;推拉单元,所述推拉单元能够直线伸长或者收缩,所述推拉单元的工作端销轴连接在所述摆臂的侧壁上,所述推拉单元的底端销轴连接在所述主梁体的顶面上。本发明还公开了一种摆臂式调整起吊重心吊梁工作方法。本发明技术方案通过推拉摆臂沿转轴旋转,改变起吊点相对起吊梁的左右位置使得平稳起吊,同时能够实现被吊物起吊状态的调整。
