The invention relates to the technical field of lifting devices, and discloses a high-safety lifting device which comprises a fixing table, a supporting frame is arranged at the top of the fixing table, a rotating rod is arranged on the outer surface of the supporting frame, a wire roller is fixedly connected to the outer surface of the rotating rod, and a rotating shaft is fixedly connected to one end of the rotating rod. And a motor is arranged at one end of the rotating shaft. The lifting rope winding device has the following advantages and effects that the motor enables the rotating shaft to drive the wire roller to rotate, the lifting rope is wound, the bottom end of the gravity sensor is connected with the outer portion of the hook, and when the hook or a hanging chain breaks or weightlessness occurs in the lifting process of the lifting rope, the lifting rope is wound up. The bottom of the gravity sensor can sense the change of the acceleration, so that the gravity sensor can give out a hoisting fault alarm, hoisting end assemblies such as a hoisting end motor and a wire roller stop running, namely hoisting of goods is stopped, and a breakage fault protection effect on a hoisting rope and a top connecting mechanism is achieved.

    本发明涉及起吊装置技术领域,公开了一种高安全性起吊装置,包括固定台,所述固定台的顶部设置有支撑架,所述支撑架的外表面设置有转杆,所述转杆的外表面固定连接有线辊,所述转杆的一端固定连接有转轴,所述转轴的一端设置有电机。本发明具有以下优点和效果:电机使转轴带动线辊进行转动,对起吊绳进行收卷,通过将重力传感器的底端与挂钩的外部进行连接,当起吊绳在起吊过程中如挂钩与或挂链发生断裂以及失重情况时,重力传感器的底部会感应到加速度的变化,从而可使其发出起吊故障警报作用,使起吊端电机以及线辊等起吊端组件停止运转即停止对货物的起吊,对起吊绳以及顶部连接机构起到断裂故障保护作用。
