The invention relates to the technical field of hoisting, in particular to a hoisting object braking method and braking device.The hoisting object braking method comprises the following steps that firstly, when a crane is static, the mass of hoisting goods and the mass of a hoisting chain are obtained; 2, when the crane moves in a certain preset direction, the movement speed of the crane and the movement speed of the goods are obtained; 3, after the crane moves to a preset position, the crane is braked for the first time, and the horizontal displacement and time of the cargo swinging to the highest point are calculated according to the obtained mass of the hoisted cargo and the hoisting chain and the movement speed of the crane and the cargo; and 4, according to the calculated horizontal displacement and time of the cargo swinging to the highest point, before the cargo swings to the highest point, the crane is controlled to run to the position above the highest point of cargo swinging. The crane 1 is controlled to move to the position above the highest swinging point of the goods before the goods fall, so that the goods do free falling motion downwards in the vertical direction under the action of gravity, the swinging amplitude of the goods is reduced, the goods stop swinging as soon as possible, and the swinging time is saved.

    本发明涉及吊运技术领域,尤其涉及一种吊运物体制动方法以及制动装置,包括以下步骤:步骤1:在吊机静止时,获取吊运货物和吊链的质量;步骤2:在吊机向某一预设方向运动时,获取吊机和货物的运动速度;步骤3:在吊机运动至预设位置后,吊机首次制动,根据获取的吊运货物和吊链的质量以及吊机和货物的运动速度,计算货物摆动至最高点的水平位移和时间;步骤4:根据计算得到的货物摆动摆动至最高点的水平位移和时间,在货物摆动至最高点前,控制吊机运行至货物摆动的最高点的上方。通过在货物下落前控制吊机1移动至货物摆动的最高点上方,使货物在重力作用下沿垂直方向向下做自由落体运动,减少货物的摆动幅度,使货物尽快停止摆动,节约摆动时间。
