The invention provides an automatic protection device for preventing hoisting equipment from being obliquely pulled and hoisted. Comprising a bearing part used for bearing a lifted object; the power unit is used for controlling the bearing part to ascend or descend; the radar component is arranged at the bottom of the power unit, and the detection area of the radar component is a conical area with the radar component as the top and the ground as the bottom face; the radar component is used for sensing the distance between the bearing part and the bottom of the power unit, and when the distance between the bearing part and the bottom of the power unit is smaller than a first threshold value or larger than a second threshold value, a power-off instruction signal is generated; the power-off module is also used for generating a power-off instruction signal when sensing that the bearing piece exceeds the detection area of the radar component; and the power-off execution unit is electrically connected with the power unit and the radar component and is used for carrying out power-off operation on the power unit after receiving the power-off instruction signal of the radar component.

    本发明提供一种防止起重设备歪拉斜吊的自动保护装置。包括承载件,用于承载被起重物体;动力单元,所述动力单元用于控制承载件上升或下降;雷达部件,设置在所述动力单元的底部,所述雷达部件的探测区域为以所述雷达部件为顶部、以地面为底面的锥形区域;所述雷达部件用于感应所述承载件与所述动力单元的底部之间的间距,在所述承载件与所述动力单元的底部之间的间距小于第一阈值或大于第二阈值时,生成断电指令信号;还用于在感应到所述承载件超出所述雷达部件的探测区域时,生成断电指令信号;断电执行单元,所述断电执行单元与所述动力单元、所述雷达部件电连接,用于在接收到所述雷达部件的断电指令信号后,对所述动力单元进行断电操作。
